Faucets are the necessities of family life. Every household uses them. Every day, people are in close contact with the faucets, at least several times, many dozens of times. It can be seen that the intimacy between the faucets and people's life is a small accessory, but it contains University questions. Therefore, in family decoration, the purchase of faucets becomes a compulsory course for home owners. So how can we choose a faucet that is water-saving, beautiful and of good quality?
Rotary handle: feel light valve spool is good
Common tap spools are steel ball spools and ceramic spools. The steel ball valve core has good pressure resistance, but the disadvantage is that the rubber sealing ring which plays a sealing role is easy to wear out and will soon aging. Compared with the steel ball spool, the ceramic spool is more heat-resistant and wear-resistant. At the same time, the ceramic spool itself has good sealing performance, so it can achieve a high number of open times, and will not cause water nozzle leakage due to the wear of the spool. The faucet with ceramic spool is more comfortable and smooth in handle, and it opens and closes quickly. Because the valve spool is inside the tap, consumers can not see the valve spool when choosing to buy, but consumers can simply judge whether the valve spool is good or bad according to the feeling of turning the handle. Generally speaking, consumers turn the handle up, down, left and right, if it feels light and non-blocking, then the valve core is better.
Look at the appearance: The coating should be as bright as a mirror.
After grinding and polishing the faucet, the surface should be plated with nickel or chromium, oxidized by the waterproof faucet, and tested with medium hydrochloric acid after nickel or chromium plating. After the test, the coating should be free of rust for a certain period of time. It is understood that only through the neutral salt spray test faucet can leave the factory. When choosing and purchasing, consumers should place the faucet in a place with sufficient light to observe. The surface of the faucet should be bright as a mirror, without any oxidation spots, charred marks, no air holes, no blistering, no leakage plating, uniform color; touch the faucet with hands without burrs and sand grains; press the faucet with fingers, the fingerprints will quickly disperse, and dirt will not be easily adhered to.
Testing: Quality is more assured
The main body of the tap is usually brass. The plating quality of products made of brass can be guaranteed the best. The higher the purity of brass, the better the plating quality, and the less likely the electroplating layer on the surface is to be corroded. In order to reduce costs, some manufacturers choose zinc alloy instead of brass. Although the state allows the use of zinc alloy instead of brass, the quality of zinc alloy plating is poor and the corrosion resistance is not strong. Generally speaking, consumers can use the method of weight estimation to identify when choosing and purchasing. Brass is heavier and harder, and zinc alloy is lighter and softer. Experts caution that the quality of faucets should not be judged by weight alone, because some manufacturers can make faucets heavier by increasing the wall thickness of faucets or adding other metal materials. Consumers had better ask the salesperson for the product test report. If the test report confirms that the product is qualified, the "problem is not big".
Water flow test: rich foaming is the criterion
When choosing and purchasing, consumers should try to choose the faucet with foamer, and feel the water flow with hand touch. The soft and rich water flow (water bubble content) indicates that the quality of the foamer is better. Bubblers usually have six layers, usually consisting of a metal mesh cover (partly plastic). When water flows through the mesh, it will be cut into a large number of small water columns with air in the middle, so that the water will not split.
