The copper faucet has occupied a large part of the hardware industry market so far, and the reasons are obvious: 1 mature processing technology, lower processing cost; 2 material determines the ease of processing, and can shape and color at will; 3 copper is easy Electroplating, the appearance brightness can be controlled at will. After the test of time, the inside of the copper faucet cannot withstand the corrosion of 'rustYes, copper will rust, commonly known as patina. The patina contains lead, which can cause an impact on the human central nervous system and affect intelligence. In addition, China's better electroplating technology can only prevent the surface of the copper faucet from peeling for 5 years, and the patina will become the surface of the faucet after peeling. what does that mean? The copper faucet will be replaced in about 5 years.
With the improvement of quality of life and increased awareness of environmental protection, people began to reject copper faucets that produce lead and electroplating techniques that discharge heavy metals. As early as 5 years ago, 304 stainless steel sanitary wares have emerged in European and American countries. 304 stainless steel is a metal that can be implanted in the human body. It is healthy, does not rust, and has zero lead. The surface layer does not need to be electroplated, and the gloss of the surface can be preserved for 10 years, 20 years or even longer by drawing and polishing. It is easy to clean and only needs to be wiped with water.
Some domestic 'copper' bosses are also aware that copper faucets are beginning to go downhill, and they have begun to transform the production of stainless steel faucets. However, the production technology of stainless steel faucet is very demanding, which is not completely consistent with the production line of copper faucet. Therefore, many manufacturers have been unable to withstand the production process-the pressure of low yield due to low technology, 'repeated mistakes.' Taking into account the health of the people in the country. China cannot fundamentally lag behind with others.
