The most important factor is to select the valve core of the faucet, which is the key part in the faucet. Some taps leaked water soon after they were used, because the spool was not qualified. So should choose ceramic valve core. >>>Recommendation:PPR Water Pipe Selection and Installation When selecting specific items, the following points should be noted: 1, see the surface brightness. The valve body of the faucet is cast from brass and the surface is plated with nickel and chromium. When purchasing, pay attention to the surface luster, hands should be no burr, no pores, no oxidation spots. 2, gently turn the handle to see if it is light and flexible. 3, check the various components of the faucet, especially the main components are closely assembled, there should be no loose feeling. The valve body and handle of a good faucet are all made of brass and have a heavy weight and a sense of dignity. It is difficult for the faucet to identify whether there is leakage before it is connected to the water source. The quality of the faucet can be judged by checking whether there is any looseness in its connecting parts. Because this loose type can cause direct leakage of the faucet. 4, identify product tags. General regular goods have manufacturer's brand identity in order to identify and prevent counterfeiting. Some non-regular products or quality products are often affixed with only paper labels, even without any marking. Must pay attention to distinguish when purchasing. Sanitary ware purchase faucet
Resin bond is a kind of organic bond, the grinding wheel made of this bond has high strength, has certain elasticity, low heat resistance, good self-sharpening, easy production and short process cycle. It can manufacture Grinding Wheels with working speed higher than 50 m/s and very thin grinding wheels. Its application range is second only to ceramic binder, widely used in rough grinding, waste grinding, cutting and free grinding, such as grinding steel ingot, casting burr etc.. Can manufacture high speed, high finish grinding wheel, heavy load, cutting and various special requirements of grinding wheel.
In tool grinding, the cutting tool materials with high hardness, thermal hardness, wear resistance and enough strength and toughness, such as carbon tool steel, alloy tool steel, high speed steel, hard alloy, etc., are grinded with resin strong grinding wheel to achieve ideal accuracy. The surface roughness and correct geometry make the cutting edge have high sharpness and durability
