Faucet is the most commonly used material in the home. Faucet materials are divided into stainless steel, plastic, copper, ceramic, zinc alloy, etc. It is often heard that the lead in the faucet exceeds the standard, which brings safety hazards to family life. In home decoration, copper faucets are used more. Copper has antibacterial, corrosion resistance, and sterilization effects, but it contains a small amount of lead and is not bright enough. It is used more in home decoration and is at a moderate price. Ceramic faucets are more expensive than copper faucets. These faucets are high-end, durable, corrosion-resistant and can be used by families with good economic conditions. So how to choose a faucet to avoid this problem?
The harm to the human body caused by excessive lead in the faucet is unimaginable, so we must learn to protect ourselves. In order to prevent the faucet from being oxidized, the surface of the faucet will be plated with a layer of nickel or chromium after being polished and shaped. The nickel or chromium has the function of resisting neutral hydrochloric acid and protects the faucet from corrosion for a long time. When purchasing, check in a well-lit place. The faucet surface has no oxidation spots, no pores, no leakage of plating, bubbles, and burn marks, and a good product is a product with a uniform color and no burrs and sand.
Secondly, when buying a faucet, you must look at the faucet’s inspection certificate to see whether the lead content of the faucet meets national regulations; secondly, in daily life, you must take in more trace elements, such as copper, iron, magnesium, zinc, etc. Because these trace elements can interact with lead to reduce the harm of lead to the human body; finally, you must have a sense of self-protection and safety in your life, and you must not buy unqualified faucet products cheaply. If you buy a well-known brand faucet, you must check whether the lead exceeds the standard, so that you can be more sure of its safety.
Develop and clean the outer coating to protect the coating of the faucet. When cleaning, you should wipe it with a wrung soft cotton cloth. Do not wipe it directly with a wet towel to avoid leaving limescale. Do not wipe with burrs to damage the coating. Avoid letting the faucet come into contact with acid-base liquids. You can spray a neutral detergent on a soft cloth and then gently wipe the faucet.
Clean up the impurities in the screen in time. If after a period of use, the water output is found to decrease, or even the water heater is turned off, it may be that the screen is blocked by water and sand. At this time, gently unscrew the screen cover at the water outlet of the faucet to remove impurities. Generally speaking, cleaning the impurities of the screen regularly, once every three months at the longest, is better for the water quality and the health of the family.
Replace the faucet regularly. Nowadays, chlorine is often used as a disinfectant in tap water, and the residual chlorine compounds in the water will aggravate the precipitation of lead in the tap. Generally speaking, if the copper alloy faucet is used for more than 5 years, the amount of lead precipitation will greatly increase. Therefore, it is recommended that the faucet in residents' homes should not be used for too long.
