Mercury switch contacts are impractical to build in large sizes, and so you will typically find such contacts rated at no more than a few amps, and no more than 120 volts. A switch may be directly manipulated by a human as a control signal to a system, such as a computer keyboard button, or to control power flow in a circuit, such as a light switch Automatically operated switches can be used to control the motions of machines, for example, to indicate that a garage door has reached its full open position or that a machine tool is in a position to accept another workpiece. These other types of contacts are sealed from contact with the outside air, and therefore do not suffer the same exposure problems that standard contacts do. A puffer may be used to blow a sudden high velocity burst of gas across the switch contacts, which rapidly extends the length of the arc to extinguish it quickly. Many are designed to provide the simultaneous actuation of multiple sets of electrical contacts , or the control of large amounts of electric current or mains voltages. Bounce in SPDT switch contacts signals can be filtered out using a SR flip-flop (latch) or Schmitt trigger All of these methods are referred to as 'debouncing'. Switches are made in many different configurations; they may have multiple sets of contacts controlled by the same knob or actuator, and the contacts may operate simultaneously, sequentially, or alternately wall sockets manufacturer. 1 2 The most common type of switch is an electromechanical device consisting of one or more sets of movable electrical contacts connected to external circuits. There are many different types of switches, and we will explore some of these types in this chapter. Electrical switches.
Accelerometer Basics - Motion-sensing accelerometers - like those in most smartphones and new video game controllers - are fast-replacing these boring switches as human input devices. Conversely, if a button usually acts like a short circuit unless actuated, it's called a normally closed (NC) switch. A push button is a simple type of switch that controls an action in a machine or some type of process. When the contacts are separated by an insulating air gap , they are said to be "open", and no current can flow between them at normal voltages. With low-energy LED bulbs, there's really no reason not to. The dimmer switches do cost more, so we don't have them throughout, but we're pleased with the distribution. The "poles" of a switch refers to the number of moving contacts, while the "throws" of a switch refers to the number of stationary contacts per moving contact. Ordering: For colored illumination, order the Pushbutton, Case, Lamp, and Switch separately. Push Button Switch Operation Push button switches typically have two key parts, an actuator and the contacts. Being a liquid, it can be brought into contact with metal probes (to close a circuit) inside of a sealed chamber simply by tilting the chamber so that the probes are on the bottom. Aesthetic of switch: Push buttons often come with a couple of options for the button. Heat generated by current through metal contacts (while closed). Momentary switches require the user to keep holding the button for an action to take place, this action is then reset once the button is released. One or more positions of the switch may be momentary (biased with a spring), requiring the operator to hold the switch in the position. Therefore, contacts that are open in this position are called normally open and contacts that are closed in this position are called normally closed. These types of light switches are usually found at the top and bottom or a hall way of a flight of stairs. In control logic symbology, this capacitor symbol is used for any type of capacitor, even when the capacitor is not polarity sensitive, so as to clearly distinguish it from a normally-open switch contact. Basically two SPDT switches, which can control two separate circuits, but are always switched together by a single actuator. The Arduino Pro has two SMD switches: a slide switch for power control, and a push-button for reset control. Transistors - These can be used (among many other things) as sort-of electronically controlled switches. Toggle switches have a long lever, which moves in a rocking motion. Switch contacts may be debounced electronically, using hysteretic transistor circuits (circuits that "latch" in either a high or a low state) with built-in time delays (called "one-shot" circuits), or two inputs controlled by a double-throw switch. You're possibly looking for the most common of switches, which most electricians refer to as a single-pole light switch. Note: If the Pushbutton is pure yellow (PY), use white (W) for the Switch Unit. Using mercury to "wet" the contacts is a very effective means of bounce mitigation, but it is unfortunately limited to switch contacts of low ampacity. A toggle switch in the "on" position. Some switches are used to isolate electric power from a system, providing a visible point of isolation that can be padlocked if necessary to prevent accidental operation of a machine during maintenance, or to prevent electric shock. Another common switch-type is the SPDT. Reed switches are another type of sealed-contact device, contact being made by two thin metal "reeds" inside a glass tube, brought together by the influence of an external magnetic field. Toggle switches are commonly SPST (two terminals) or SPDT (three terminals), though you can find them in other flavors as well. Rotary switches were used as channel selectors on television receivers until the early 1970s, as range selectors on electrical metering equipment, as band selectors on multi-band radios and other similar purposes. A wireless light switch allows remote control of lamps for convenience; some lamps include a touch switch which electronically controls the lamp if touched anywhere. The effect is usually unimportant in power circuits, but causes problems in some analogue and logic circuits that respond fast enough to misinterpret the on‑off pulses as a data stream. This is a switch where when the user flips the lever up, the electrical circuit is complete and the light switches on and when the lever is flipped down the circuit is broken and the light turns off. For example, a radio controlled overhead crane may have a large multi-circuit rotary switch to transfer hard-wired control signals from the local manual controls in the cab to the outputs of the remote control receiver. NC switches are push-to-break”; actuating the switch creates an open circuit. Commonly you'll see switches defined as single-pole, single-throw”, single-pole, double-throw”, double-pole, double-throw”, which are more often abbreviated down to SPST, SPDT, and DPDT, respectively. Unlike the mercury switch which uses liquid metal as the contact medium, the reed switch is simply a pair of very thin, magnetic, metal strips (hence the name "reed") which are brought into contact with each other by applying a strong magnetic field outside the sealed tube. A "push-to-break" (or normally-closed or NC) switch, on the other hand, breaks contact when the button is pressed and makes contact when it is released. This means that our customers can match their style of switch to the room they are placing it. We also offer a few different plate fixings which are clip-in, screws or also offer light switches that are illuminated, neon or LED, these are a great solution for when you are looking to see where the switch is when the switch is off of dimmed down low. The Digital black can be easily mounted in a standard flush-mounting box and is powered on 230V AC. This 230V AC variant is equipped with a switching contact 10 A (resistive), meaning that it can easily be replaced with a conventional single-pole switch. The bending of the strip can then be used to actuate a switch contact mechanism. The parts of a switch responsible for making and breaking electrical continuity are called the "contacts." Usually made of corrosion-resistant metal alloy, contacts are made to touch each other by a mechanism which helps maintain proper alignment and spacing. Push-button switches are two-position devices actuated with a button that is pressed and released. This last type of push-button switches usually have a mushroom-shaped button for easy push-pull action. The term 'switched' is also applied to telecommunications networks , and signifies a network that is circuit switched , providing dedicated circuits for communication between end nodes, such as the public switched telephone network The common feature of all these usages is they refer to devices that control a binary state : they are either on or off, closed or open, connected or not connected. Ceramet produces G-METAL, a unique, self lubricating material for wear surfaces. We can produce small to very large bearings from bronze, stainless steel, and steel alloys with outer diameters up to 124” and assembly weights up to 35 tons. 1 relative to a prior art journal bearing 9 fabricated with a metal housing 11 and a maintenance free bearing 10 including a plastic load bearing layer as generally described hereinabove. For bearings and shoes, this self-lubricating material consists of a bimetal structure — a stainless steel support and a bronze sliding layer with small particles of graphite solid lubricant homogenously distributed. The self-lubricating segments of the shoes and the flanges of the bronze bearings are fixed with countersunk screws. Oilite bearings are manufactured in three standard materials. LUBRON AQ's low friction and abrasion resistant properties help minimize wear and extend bearing life.

LUBRON AQ self-lubricating bearings feature a combination of properties and capabilities unsurpassed by other maintenance-free bearings. 9. The method of claim 8, wherein said load bearing layer is selected from the group consisting of fluoropolymers, polyimide and aromatic ketones, and combinations thereof. Smoother finishes are normally required for harder materials, higher loads, and higher surface speeds. 2 is the side view of the described a kind of oil-less self-lubricating bearing of the utility model embodiment. Throughout this disclosure, the terms "self-lubricated" or "self-lubricating" shall refer to use of a material that exhibits sufficient lubricity to nominally eliminate the need for application of a discrete lubricant to a bearing surface. This invention relates to bearings, and more particularly to a maintenance free bearing having a lubricious wear layer that is resistant to creep. 11 S.Q. Niu, J.P. Zhu, J.L. OuYang: Study of Several High Temperature Self-lubricant Materials Vol. They offer a greater lifetime than the other bearings types an materials. A further objective of the present invention is to provide a self-lubricating bearing, wherein the bearing is made of bronze. Just enter your requirements, including design, load, speed, shaft material and housing, and instantly see how many hours each suitable material could last inside your application. Such bearings provide convenient means for rotatably, pivotably or slidably fastening multiple members to one another in a maintenance free manner. Advances in technology coupled with the need for energy-efficient and high-performance bearings in industrial equipment and machinery will further assist in the growth of the self-lubricating bearings market. Our range of oil-impregnated sintered bronze bushings is intended for use in maintenance-free operations, under moderately high speeds and low loads. 2. Bearing material according to claim 1, characterized in that the Kumtstoffmatrix besides PTFE also PEEK, PPS, PA, PVDF, PSU, PES or PEI individually or in combination. The article highlights a lower cost, easier-to-maintain machine component that eliminates the total cost of bearing lubricants: high-performance, dry-running plastic bearings. Bronze bearings are cast, machined & lubricated & are available with maximum pressure up to 1,000 psi at 800 degrees F temperature. When self-lubricating bearings are custom designed, you can specify what material and oil should be used, as well as the shape, tolerance, and assembly method that you require. The self-lubricating block, for example, uses a solid lubricant that is a mixture of polymers, oils, and select additives that reduce the penetration of dirt, grit, and liquids into the ball path, preventing premature failures. The creep and delamination problems may be addressed by roughening the metal backing surface, such as by sandblasting, etc., prior to application of the bearing surface. Applications with high loads and high speeds—these lead to excessive frictional heat build-up and wear. Oilite bearings are the most popular self-lubricating bearings in the UK, but they are also in high demand in Europe. Custom manufacturer of self-lubricating ball bearings, linear motion systems and components. Solid plugs of graphite are usually inserted into holes in the base bronze material. Oilless bearing , Oilless bush ,Graphite embedded bearing, self lubricating bearing, Non ferrous bearing , liners , wear pad etc. When circumstances necessitate field machining the lubricated bearing surface, consult a LUBRON engineer for specific recommendations.
36 Y.H. Xia, Z.R. Jin, J.G. Cheng: The Use of Gradient Self-lubricating Bearing Materials in Engineering Materials Vol. Total cost of ownership — While purchase price of a self-lubricating bearing might be 10 to 30 per cent higher than the cost of a bearing requiring manual lubrication, the reduced labour costs, elimination of need for lubrication assemblies, improved performance, and reduced downtime compensates for it. Poor lubrication is implicated in half of all bearing failures. 2. A bearing as set forth in claim 1 wherein the capillary flow suction action applied to the lubricant to cause it to flow into said bearing clearance is adapted to the relationship S12 >S13 >S3, wherein S12 is the suction capability of the bearing clearance between the shaft and the bearing surface means, S13 is the suction capability of said clearance between the shaft and the porous member, and S3 is the suction capability of the porous member. For more than 10 years, self-lubricating, or lube-for-life, designs have used oil-saturated polymers in linear bearing applications ranging from food processing to automotive assembly. For water treatment plant or any other industrial process using water, Thordon Bearings have been developed to offer an exceptional abrasion wear resistance. Thereafter, load bearing layer 114 may be applied to the tube in any convenient manner, such as, for example, by spray coating or dipping. In such cases, LUBRON AQ bearings can be furnished with one of several groove patterns to accommodate most types of loading, movement and lubricating requirements. The utility model relates to an oil-free self-lubricating bearing, which comprises a bearing body, the top end of the bearing body is provided with a bearing house; the bearing housing is internally provided with a steel ball, and a layer of self-lubricating layer is arranged between the steel ball and the inner surface of the bearing housing. The good mechanical properties of the sintered bronze along with the good sliding and lubricating properties of a PTFE mixture are optimally combined in the case of the GLYCODUR F slide bearings. The entire laminate is then preferably inserted into a conventional press under heat and pressure wherein load bearing layer 114 is provided with outermost surface 122 as shown in FIG. The material is then subjected to a heat treatment in an oven, in which the PTFE it contains is sintered at 380 ° C. for 3 minutes in order to achieve a final rolling step to produce the final composite and the required gauge block. The solution adopted — to implement the use of self-lubricating material replacing grease lubricated bearings and PTFE foil — has provided better safety for energy production in a sustainable manner following company concerns with the social and environmental aspects of its business. The material can be formed into many shapes and sizes including wear plates, rolled bushings, cylindrical bearings, spherical bearings, split bearings, sleeves, liners, guides and other customizable shapes. In the event that your requirements cannot be met by stock items, our bespoke service enables us to produce both bronze and iron Oilite bearings and customer specific structural parts that are specifically designed to meet individual requirements. The lubrication is consistently applied to the shaft surface. A 1989 report described the friction and wear at an elevated temperature (300°F-500°F) of several thermoplastics compounded with PTFE, other lubricants, and CF.70 The thermoplastic resins that were evaluated were PEEK, PEK, PES, and PPS. 2 and 3, the present invention comprises a bearing 110 having a backing or substrate 112 fabricated from a metallic or other material capable of providing bearing 110 with requisite structural integrity for an intended application. Deva.glide is a self-lubricating bearing material that consists of a high quality bearing bronze with solid lubricant pockets. Highly porous materials have a high stiffness combined with a very low specific weight due to very high porosities. I understand these are a composite construction bearing made from a combination of PFTE (better known as Teflon), Lead, Bronze, Steel and a copper plating, not being a metalurgist and these coming from china though, who really knows. ISO 9001:2000 & AS 9100B certified manufacturer & distributor of standard & custom bearings including oilless or self-lubricating bearings. Self-lubricating pillow block assemblies, open or closed, are commonly available for shaft sizes ranging between ½” and 1½”, with loads ranging from 250 to 4,000 pounds, but can be customized. Graphite is used in products for the following reasons: conductivity, EMI shielding, lubricating coatings, self-lubricating bearings, lubricants, heat, chemical, and water resistance, flame retardancy, release properties, and pigmentation. 7 M.M. Shi: Solid Self-lubricating Materials Vol. The main advantages of material when compared to PTFE foil are its higher load capacity, as PTFE foils can be deformed when submitted to high loads, and its longer lifetime. In this regard, the bearings are provided with a relatively low coefficient of friction, long bearing life, resistance to creep and mechanical stresses, and are electrically and thermally conductive. One form of self-lubricating plain bearing comprises a metal capillary bearing member formed from metal powder with or without graphite by pressing under a high pressure in a mold, followed by sintering in a hydrogen atmosphere. Whenever reference is made to bronze with graphite, it is safe to assume that bronze plugs have been embedded in the bronze bearings. Moreover, the coefficient of friction of the NORGLIDE bearing may be lower than other prior art bearings due to the ability to utilize reduced filler content or fillers that have less negative impact on the coefficient of friction. In operation of the bearing the lubricant is sucked out of the pores of the bearing member and supplied to the bearing surface of the sintered member and the shaft, by the rotating shaft, as a result of suction and an increase in temperature, due to capillary action, according to the speed of rotation of the shaft. Bearings should be sized to accommodate the total applied load without exceeding the maximum design load. 11. A bearing as set forth in claim 10 wherein said porous member comprises spheroidal sintered bronze. The advantages conferred by this self-lubricating layer include a low coefficient of friction and high load capacity — up to 36,260 pounds per square inch (psi) compared to the 1,450 psi achievable with sintered bronze bearings. 7. A bearing as set forth in claim 1 wherein the porous member comprises spheroidal sintered bronze. A preferred material for the member 1 is a sinter material comprising spheroidal particles, more particularly bronze, thereby making it possible to produce porosity which is uniformly distributed throughout the sintered member so that there is substantially no possibility of regions of different suction capability within the porous member. In another application, a swinging hinge assembly used to support PVC swinging strip doors — used for quick loading bay access — has been using maintenance-free, all-plastic plain bearings since 1998 with no problems. In the rolling process, the pores of this layer are filled with polytetrafluoroethylene (PTFE) mixed with friction and wear-reducing additives. The third, lubrication-free option is to use injection-molded solid polymer bearings. In order to properly integrate the bearing into a linear motion system, the linear shafting needs to be cleaned with a 3-in-1® type of oil to ensure a clean transfer of material. 16. The method of claim 15, wherein said load bearing layer is applied to said substrate by heat and pressure. These are porous, sintered-metal bearings. A method is provided for fabricating a self-lubricating bearing as a laminate of a metallic substrate and a series of raised structures formed integrally therewith and extending orthogonally therefrom. With the correct lubrication, slide bearings almost non-wearing. The lubrication (typically oil or grease) is NOT added to the original bearing design. Proper lubrication delivery is critical for the operation of ball bearings, and most require continued maintenance for re-lubrication. 33 T.S. Li: The Development of Gradient Self-lubricating Bearing Materials Vol. Reinforcing fillers are added to increase the lubricant's resistance to deformation under load and distortion due to elevated temperatures. 2. Bearing layer 114 may be subsequently formed by laminating a conventional sheet of lubricious material, such as PTFE, using a suitable adhesive as described hereinabove. It is a self-lubricating bearing with graphite plugged to base metal. Self-lubrication allows this type of sliding bearing to work under hydrodynamic conditions, resulting in a very low friction coefficient. A bearing surface means such as a sleeve for supporting the shaft is disposed in the bore adjacent to the porous member and extends outwardly of the bore from the porous member. The study provides a decisive view on the self-lubricating bearing market by segmenting the market based on applications. The effect normally produces very fine scale porosity when the interdiffusion rates of the two metals are not equal and has been observed to occur at a sufficient level to generate a porous material with NiTi and Ni3Al (He et al., 2007; Dong et al., 2009; Wen et al., 2010; Liang et al., 2011), but has also been used as a means of increasing porosity by adding to the pore fraction (Wang et al., 1998) or by expanding a percolating network of particles (Ismail et al., 2011). The shaft 2 does not touch the porous member 1 so that no metal-to-metal friction occurs, even at low speeds of shaft rotation. Products include bearing pads cut or stamped from glass-filled PTFE materials. First and foremost, the presence of lubrication minimises the risk of seizure and thus makes these bearings more reliable than many other types. GLYCODUR F slide bearings have a copper-plated steel backing and a porous 0.2 to 0.4 mm thick, sintered-on layer of tin bronze. The DU bearing consists of a composite material in which a porous bronze layer is bonded to a metal backing. Further, sliding friction resulted from point contact occurs between the bearing according to the present invention and the shaft, leading to a small friction coefficient and consequently less wear. You will find that these bearings are typically available in several standard sizes or in solid or hollow cylinders that must be machined to the desired dimensions. Simplicity bearings can be configured with an optional lubrication system machined-in for extra lubrication. The "NX" prelubricated bearings also exhibit high load carrying capacity and extremely low friction during use. Deva.metal® is provided with an evenly distributed solid lubricant throughout its metallic matrix. ISO 9001:2000 certified manufacturer of metric, sleeve type & oilless or self-lubricating sleeves & bushings used as bearings. The minimum and maximum values shown in Tables 2 and 3 are suitable for most applications, and are based on the permissible shaft load, bushing diameter and yield strength of the bearing material. Agricultural machinery, hydraulic systems, bearings for impact loading and shock stress applications, construction machinery, bearings used in handling and conveyor technology and many more. 15 X.L. Wang, X.L. Ying, L. Gao: The Development and Trends of Solid Self-lubricant Materials Vol. As can be seen from the drawing, the clearance 5 between the surface of the member 1 and the shaft is larger than the clearance 6, although the clearance 5 is smaller than the size of the pores in the porous member 1. The above-described relative dimensions in respect of the clearance 5 and 6 and the pores in the member 1 give a graduated suction action on the lubricant, which is also of a given viscosity or viscosity range, as referred to below, in such a way that the suction capability or action of the clearance 6 on the lubricant is greater than the suction capability or action of the clearance 5 which in turn applies to the lubricant a greater suction action than the porous member 1. This arrangement therefore ensures continuous lubrication of the surfaces at the bearing clearance 6, even at low speeds of rotation as frequently occur for example in a disc record player. 13. The method of claim 2, wherein said intermediate layer comprises a metallic material. Friction is of less practical importance than the rate of wear, which is defined in terms of volumetric loss of material over time. Referring to the drawing, the bearing comprises a bearing body portion in the form of a block 7 having therein a receiving bore 4 which is closed at one end and at the bottom or closed end of which is arranged a plain support or thrust bearing member 8. A porous member 1 which may be for example a sintered member is disposed on the bearing member 8 in the bore 4, in the vicinity of the inner closed end of the bore 4. As can be readily seen from the drawing, the member 1 occupies only part of the axial length of the bore. Distributor of self-lubricating bearings. Because NG does not utilize bronze in the bearing layer and is homogeneous, the friction coefficient does not vary during its life. These self-lubricating bearings have high load capacity and are able to operate at -328 to 536 degrees F. They can be used with rotational, oscillatory and axial sliding motion. Wear rate and operation under specific loads, temperatures and speeds are all important considerations when selecting the best bearing for your application. Sintered bronze bearings function best on very hard, expensive precision-ground shafts. With too much idle time, lubricants can be pushed out of the contact area or solidify, which means friction and galling at start up. 1-2, the described a kind of oil-less self-lubricating bearing of the utility model embodiment comprises bearing main body 1, and the top of described bearing main body 1 is provided with bearing housing 2, the inside of bearing housing 2 is provided with steel ball 3, is provided with one deck self-lubricating layer 4 between the internal surface of steel ball 3 and bearing housing 2. Bowman International offers the widest choice of Oilite bearings anywhere in Europe with standard stock ranges available in metric and imperial. LUBRON AQ bearings will operate against most metals, but best performance is achieved with the hardest possible mating surface. LUBRON AQ bearings are frequently used where oil and grease lubrication are impractical. The technical training division of Life Cycle Engineering conducted a study that found 80% of maintenance workers surveyed scored less than 50% when it came to the basic technical skills needed to perform their job; and bearing lubrication was noted first on their list of tasks. LUBRON AQ bearings are constructed of high strength bronze alloys permanently embedded with PTFE solid lubricants, and are unequaled for toughness and durability. Capable of very low friction and high wear resistance, LUBRON TF bearings offer exceptional performance for hydro turbine wicket gate, control linkage, butterfly valve and dam gate applications. Self-lubricating plastic plain bearings offer technical advantages in comparison to metal or metal-backed bearings. In general, four categories of self-lubricating bearings can be distinguished and within each category further subcategories can easily be identified. LUBRON AQ bearings should be wiped clean and free of all debris prior to installation of the shafts. 1, bearing main body; 2, bearing housing; 3, steel ball; 4, self-lubricating layer. 29 X.L. Kong, Y.B. Liu, Y. L: Powder Metal Self-lubricant Materials Vol. CESP decided to eliminate the oil through the use of self-lubricating materials, and the PTFE foils solution was adopted. The beneficial effects of the utility model are: adopting metal material (being generally tin bronze, high-tensile strength brass, cast iron) is matrix, according to different motion mode inlaid solid lubrication agent, can under oil-free lubrication conditioned disjunction water lubrication condition, work for a long time, break through the narrow limitation that general bearing relies on film use; make solid lubricant and axle friction by frictional heat; form oil, powder and deposit lubricated excellent condition; both protected axle not wear and tear, and made the solid lubrication characteristic eternal again, the general copper sheathing of hardness ratio doubles; wear-resisting property also doubles; be more suitable in the heavy-duty low-speed working condition, back and forth, rotate, wave the occasion that is difficult to form with oil film such as intermittent movement, have good wear resistance, corrosion-resistant, anti-chemistry and extremely low friction factor. The current study of metal matrix self-lubricating bearing materials is summarized. LUBRON AQ bearings will perform best when the bearing assembly is designed for maximum heat dissipation and the recommended mating materials are used. For larger sizes, LUBRON AQ bearings can be refrigerated or packed in dry ice prior to installation. The technical knowledge and manufacturing expertise behind Oilite bearings have resulted in a vast array of sophisticated, high quality components that are supplied to across a wide range of industries throughout the world. Further, when compared with the conventional bearings made from the powder metallurgy process, the present bearing does not require the steps of press forming and vacuum oil-impregnation along with additional advantages, including a larger amount of oil impregnated, smaller friction coefficient, and cooling lubricant circulation. Thus the application of the conventional bearings has been restricted significantly, and further improvements are needed to achieve low friction coefficient, high wear resistance, enhanced oil storing capacity, and extend the service life of bearings. Since the bearing layer is fabricated as a discrete sheet, rather than a dispersion as in the case of the aforementioned DU bearings, the NORGLIDE bearing layer is homogeneous. A second temperature-related factor is that self-lubricating bearings tend to run faster and thus hotter because there is better control over lubricant buildup, which minimizes dripping. Mahogany furniture refers to furniture made of rosewood, rosewood and other classic mahogany wood, The high-end solid wood furniture made of mahogany, after many years of history, now has many unique advantages, such as good quality and competitive price, set practical, ornamental and value preservation in one. so everyone loves it.
