faucet is a necessity of daily life. People will have close contact with the water dragon every day, at least a few times, as many as dozens of times, which shows the closeness between this small necessity and people's life! Therefore, in the autumn home decoration, the purchase of faucets has become a necessary course for home owners. So how can we choose a faucet that is water-saving, beautiful and of good quality
turn the handle: it feels light and the valve core is good.
common faucet valve cores include steel ball valve core and ceramic valve core. The steel ball valve core has good pressure resistance, but the disadvantage is that the rubber sealing ring that plays the role of sealing is easy to wear out and will soon age. Compared with the steel ball valve core, the ceramic valve core is more heat-resistant and wear-resistant. At the same time, the ceramic valve core itself has good sealing performance, so it can achieve a high number of opening times and will not cause water nozzle leakage due to the wear of the valve core. The faucet with ceramic valve core makes it feel more comfortable and smooth, and can be opened and closed quickly. Because the valve core is inside the faucet, consumers can't see the valve core when shopping, but consumers can simply judge the quality of the valve core according to the hand feeling when turning the handle. Generally speaking, consumers turn the handle up, down, left and right. If it feels light and no blockage, it means that the valve core is better
look at the appearance: the coating should be as bright as a mirror
after the faucet is polished and formed, the surface should be nickel plated or chromium plated, and the waterproof faucet should be oxidized. After nickel plated or chromium plated, the faucet should be subject to medium-sized hydrochloric acid test. After the test, the coating should be free of rust within a certain period of time. It is understood that only faucets that pass the neutral salt spray test can leave the factory. When shopping, it is best for consumers to place the faucet in a place with sufficient light. The surface of the faucet should be as bright as a mirror, without any oxidation spots, burning marks, pores, bubbles, missing plating, and uniform color; Touch with hands without burrs and sand particles; After pressing the faucet with your fingers, your fingerprints will spread out quickly and it is not easy to attach dirt
to be tested: quality is more guaranteed
& nbsp;& amp; nbsp;& amp; nbsp; The main body of the faucet is usually brass. The electroplating quality of products made of brass is the best guarantee. The higher the purity of brass, the better the electroplating 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 to replace brass. Although the state allows the use of zinc alloy materials to replace brass, the zinc alloy electroplating quality is poor and the corrosion resistance is not strong. Generally speaking, consumers can use the method of estimating the weight to identify when purchasing. Brass is heavier and harder, while zinc alloy is lighter and softer. Experts remind that the quality of the faucet should not be judged by its weight alone, because some manufacturers can also make the faucet heavier by increasing the wall thickness of the faucet or adding other metal materials. Consumers had better ask the salesperson for the test report of the product. If the test report confirms that the product is qualified, then “ It's not a big problem &rdquo
