The effect of faucet material on water quality
April 13 , 2022
The faucet is in direct contact with the water source. Especially when not in use, part of the water in the water supply pipe is in relatively static contact with the faucet. If the faucet contains substances that affect water quality, this part of the substance will slowly melt into the water. If this part of the quality is beneficial, it can improve the water quality. If this part of the substance is harmful, it will form a water quality that is harmful to the body.
Now there are copper, zinc alloy, cast iron, plastic and other raw materials on the market. Cast iron does not need to be introduced too much, just think about the yellow water flow from the faucet in the early years, and you will know. As a chemical raw material, plastic has only a few toxic substances, and it is impossible to completely eliminate it. The zinc alloy is less harmful, but the material itself has poor strength. Materials that cannot guarantee tightness are also not suitable for faucets. Once water comes into contact with air, it is more likely to deteriorate.
Even copper is not 100% suitable for faucets. Only high-quality brass can be used as the base material for the faucet. What is Premium Brass? Brass is an alloy of copper and zinc. If it is only composed of copper and zinc, it is called ordinary brass. If it is a variety of alloys composed of two or more elements, it is called special brass. Such as copper alloys composed of lead, tin, manganese, nickel, lead, iron, and silicon. Brass has strong wear resistance. Special brass is also called special brass, which has high strength, high hardness and strong chemical corrosion resistance. In order to improve the corrosion resistance, strength, hardness and machinability of brass, a small amount (generally 1% to 2%, a few up to 3% to 4%, and very few up to 5% to 6%) is added to the copper-zinc alloy. %) Elements such as tin, aluminum, manganese, iron, silicon, nickel, lead, etc., form ternary, quaternary, and even quinary alloys, which are complex brass, also known as special brass. The best material for faucets is one of these specialty brasses.
In addition to the base material, there is also a part that is in contact with the water source and determines the quality of the seal, which is the cartridge. The best faucets available today all use ceramic cartridge. This part has an impact on the quality of the strength of the ceramic, which will not reduce the sealing due to frequent use.
