Proveedor de fábrica de grifos iVIGA
Actualmente, many daily necessities are made of copper, hierro, stainless steel and other materials. Estos materiales contienen elementos metálicos pesados.. If they are not handled properly, they may exceed the standard.
Por ejemplo, the main elements of stainless steel include manganese, cromo, y níquel. In order to maintain corrosion resistance, El acero inoxidable debe contener una cierta cantidad de cromo.. If the chromium is handled improperly, it may cause excessive chromium. In the same way, improper handling of manganese may lead to excessive manganese.
The copper alloy used to make faucets contains traces of metal elements such as iron, aluminio, y liderar. Si no hay pista, es difícil de formar durante el lanzamiento. Cuanto mayor sea el contenido de plomo, the easier the casting process. Por lo tanto, copper faucets on the market generally contain a certain amount of lead. If the factory does not do a good job of removing lead during manufacturing, it will cause excessive lead.
Otra razón es que la tecnología y los equipos de la empresa están envejeciendo., causing trace elements to be uncontrollable. Generalmente, cuando el nuevo equipo se pone en producción por primera vez, sus productos están calificados, pero cuando el equipo se utiliza durante mucho tiempo, the products will exceed the trace elements. This situation cannot be repaired from a technical point of view and can only be replaced with new equipment. Sin embargo, some factories continue to use them in order to save money. This is a technical and cost issue.
A seller of bathroom equipment told reporters that most faucets on the market now have copper cores, but the quality varies. Faucets from small manufacturers and cheaper prices are likely to exceed the lead. Esto se debe a que algunos fabricantes no compran aleaciones de latón estándar para controlar los costes., but purchase cheap lead brass as raw materials from small workshops. This kind of lead brass tends to have a high lead content, but the price is only half of the brass alloy.
Cómo distinguir los grifos inferiores del precio? An industry insider told reporters that a copper faucet with formal craftsmanship should cost more than one hundred yuan, while a faucet worth tens of yuan is likely to use lead brass.
“En comparación con productos grandes, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, y no prestará atención al problema del contenido excesivo de plomo.” A Shanghai citizen who is decorating his home told reporters.
A este respecto, some people in the industry said that domestic consumers did not pay enough attention to the quality and safety of faucets, which also gave many unqualified and low-quality faucets an opportunity.
