Fornecedor de fábrica de torneiras iVIGA
Atualmente, many daily necessities are made of materials such as copper, ferro, aço inoxidável, etc.. Esses materiais contêm elementos de metais pesados, which may cause excessive standards if not handled properly.
Por exemplo, the main element of stainless steel contains manganese, cromo, e níquel. To maintain corrosion resistance, o aço inoxidável deve conter uma certa quantidade de cromo. If the chromium is not handled properly, it may lead to excessive chromium. Similarly, improper handling of manganese may result in excessive manganese.
The copper alloy used to make the faucet contains trace amounts of metal elements such as iron, alumínio, e liderar. Se não houver chumbo, é difícil formar durante a fundição. Quanto maior o conteúdo do lead, the easier the casting process is. Portanto, the copper faucet on the market generally contains a certain amount of lead. If the lead-free process is not done well when the factory is manufactured, it will lead to excessive lead.
Outra razão é que a tecnologia e os equipamentos da empresa estão envelhecendo, resulting in the control of trace elements. Geralmente, quando o novo equipamento é colocado em produção pela primeira vez, seus produtos são qualificados, mas quando o equipamento é usado por muito tempo, the trace elements of the product will exceed the standard. This situation cannot be repaired from a technical point of view, and only new equipment can be replaced. No entanto, some factories continue to use it in order to save money. This is a technical problem and a cost issue.
A bathroom equipment seller told reporters that most of the faucets on the market today are copper cores, but the quality is not good. Small manufacturers, cheap faucets, the possibility of lead exceeding the standard is very large. Isso ocorre porque alguns fabricantes não compram ligas de latão padrão para controlar custos, but purchase cheap lead brass from small workshops as raw materials. This lead brass is often high in lead but at half the price of brass alloy.
Como distinguir torneiras inferiores do preço? Some insiders told reporters that a copper faucet with a formal process should cost more than 100 yuan, while tens of faucets are likely to use lead brass.
“Em comparação com produtos grandes, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, e não prestará atenção ao problema do conteúdo excessivo de chumbo.” A Shanghai resident who is renovating at home told reporters.
A respeito disso, some insiders said that domestic consumers pay insufficient attention to the quality and safety of faucets, which also makes many unqualified inferior faucets have opportunities.
