It is understood that in recent years the most complaints of the bathroom industry is the hardware accessories, the lack of adequate attention to the company is also one of the main reasons for the low pass rate of bathroom hardware parts sampling inspection over the years. According to industry sources, at present, domestic sanitary ware products can be compared with international brands in terms of product appearance, function setting and overall quality. The only regret is that there is still a certain gap in service life. For bathroom products, the key factor that determines the service life is hardware and water.
Nowadays, various types of sanitary plumbing hardware accessories on the market have various types and different functions, which make many consumers pay attention. Taking the most common faucets as an example, there are many appearances of faucets on the market, and the surface sealing is very good. In addition to the brand and price, it is difficult for consumers to truly understand the internal structure of the faucet and the valve core when purchasing. The quality of the situation. So how do you choose a faucet with better quality without opening the faucet? How do you do a good job of maintaining it and extending its service life on weekdays?
A: The Tips When You Buy 1. Look at the appearance: The chrome plating process on a good faucet is very particular about the process. Generally, it takes several steps to complete it. Resolving a faucet depends on its brightness. The smoother and brighter the surface, the better the quality.
2. Turn the handle: When the faucet turns the handle, there is no excessive clearance between the faucet and the switch, and the opening is easy and unrestrained. Poor quality taps not only have large gaps, but also have a large sense of obstruction.
3. Listen to the sound: The leading material is the most difficult to distinguish. A good faucet is cast copper as a whole and it sounds boring when struck. If the sound is very brittle, it must be stainless steel, and the quality will be worse.
4. Recognition Mark: If you can't tell, you can choose a regular brand. General regular goods have manufacturer's brand identity, and some non-regular products or some quality products often only stick some paper labels, and even without any mark, must pay attention to when purchasing.
II: Maintenance Precautions If the faucet is selected, improper maintenance can affect its service life. This is also the most troublesome thing for many people. The frequency of use of the faucet is quite high. Basically, the faucet is used every day in daily life. With such a high frequency of use, how can the faucet be maintained so that it can last longer? In fact, this is not a difficult task. As long as the correct installation, use, and maintenance of the faucet are used, the actual service life of the faucet can be extended and it can always be bright as new.
1. When the gas temperature is lower than zero, if you find that the handle of the water tap has an abnormal feeling, you must use hot water to shower the sanitary product until it feels normal. Otherwise, it will affect the service life of the valve core.
2. The phenomenon of water dripping after the faucet is turned off is due to the presence of water in the cavity after the faucet is closed. This is a normal phenomenon. If there is a dripping situation for more than ten minutes, it is a leak, indicating that the product has quality problems.
3. As the water contains trace amounts of carbonic acid, it will easily form scale on the metal surface and cause scale corrosion on the faucet surface, which will affect the cleaning and service life of the faucet. So always use a soft cotton cloth or sponge with neutral soap water to wipe the surface of the faucet, (Caution: do not wipe with corrosive or acidic substances), then dry the surface with a soft cloth. Do not use metal filaments or scouring pads with hard particles. In addition, must not hit with the hard object so as to damage the surface of the nozzle.
4. Do not use too much force to switch the tap. Gently turn the tap. Even traditional taps don't need to be screwed to death. In particular, do not use the handle as a handrail to support or use it. Many people are accustomed to making certain efforts to close the tap after using the faucet. This is very undesirable. This will not only prevent water leakage, but will also cause damage to the sealing valve, leading to lax closure.
5. Smaller water flow to clear impurities. In the case of water pressure not lower than 0.02mpa, if the amount of water found is reduced, it may be blocked inside the faucet. The solution is to use a wrench to gently unscrew the water nozzle screen cover at the water outlet of the faucet. After cleaning the impurities, carefully install it. Generally, it can be restored.
Flap Disc
Flap disc, commonly known as flat emery cloth wheels, emery discs, flower impellers or elastic grinding discs, are a large variety of coated abrasive conversion products, which press the cut coated abrasive sheets one by one. It is formed by sticking adhesive to the back cover plate along the circumference. The flap disc are called strong elastic grinding discs. They are made of calcined emery cloth, which uses mesh, nylon, plastic, steel paper and other materials as the base. Attached abrasive tools, evenly distributed in a fan shape to ensure the best grinding effect. The particle size is 36#-320#, 60# and 80# are the most common, and the outer diameter is 4"-7" installed on the angle grinder. Angle grinders are mainly installed on hand-held Power Tools to polish and polish welds, burrs, chamfers, surface rust removal, and surface polishing of various metal and non-metal parts.
The flat emery cloth wheel (flap wheel) is formed by sticking multiple emery cloth sheets on the tray in a fan-shaped superimposed arrangement, and the bonding angle between each emery cloth and the tray plane is 10°-30°. The emery cloth arrangement of the utility model can make When the abrasive cloth wheel grinds and polishes the workpiece to be processed, the cutting angle is optimized to ensure that the base material of the abrasive cloth wheel and the grinding are consumed simultaneously, which obviously improves the overall wear resistance and grinding efficiency of the flat abrasive cloth wheel, and prolongs the service life of the abrasive cloth wheel. Grind the surface of metallic and non-metallic materials.
product advantages:
Compared with the resin grinding wheel for fixed abrasives, it has the advantages of polishing and polishing at one time, shortening the operation time, saving the grinding cost, high efficiency, good heat dissipation, high grinding efficiency, reducing operator fatigue, increasing machine life, etc. It has strong elasticity, High tensile and bending strength and good grinding effect. The grinding speed is fast, the effect is good, and the noise during grinding is low. It is suitable for various industries or fields of manufacturing such as major metal parts factories and machinery factories. Good weather resistance, salt spray resistance and heat resistance, suitable for use in different regions.
Scope of application:
It is suitable for polishing of stainless steel, metal, metallurgy, automobile, wood, marble and other industries. It is especially suitable for the processing of stainless steel and can replace the resin-shaped grinding wheel. It has strong elasticity, high tensile and bending strength, good self-sharpening, high grinding rate, and low noise. It is suitable for welding seams in the box. Polishing of the edges.
There are different classifications of louvers according to different angles. The following are two common classifications:
According to the appearance: T27 VS T29
Flap disc generally have two shapes, curved and flat.
The flap disc type is also called the T27 type, and the curved type generally refers to the T29 type.
The flap disc type (T27) has a flat surface. It is mainly used to polish the flat surface and the external edges and corners. The flap disc and the workpiece are angled during work, which can complete the grinding and polishing at one time, reducing the work flow.
The curved surface of the curved louver (T29) has an upward arc, which makes the T29 flap disc have a better cutting ability on the plane. When working, the T29 type grinding wheel forms an angle of 15° to 25° with the grinding surface, which is mainly used to deal with the grinding of contours and edges. When there are higher requirements for speed and cutting ability, T29 flap disc is undoubtedly the best choice.

According to the type of abrasive particles: ceramic alumina VS zirconium corundum VS alumina
According to the type of abrasive selected, the flap disc can be divided into three types: ceramic alumina, zirconium corundum and alumina.
Because ceramic alumina itself has many crystals, it has good self-sharpening, relatively neat edges, good heat dissipation, and long service life. Therefore, ceramic alumina louvers are mainly used for the grinding of stainless steel, aluminum and other hard metals.
Zirconium corundum itself is a polycrystalline crystal, with fast cutting speed, good self-sharpening, and strong resistance to high pressure and high temperature. Therefore, zirconium corundum louver blades have strong cutting ability and long service life.
Alumina: single crystal, the cutting ability begins to decline at the beginning of grinding, and the abrasive grains are not easy to break, so the alumina flap disc is suitable for the processing of common metals.
