På nuværende tidspunkt, many daily necessities are made of materials such as copper, jern, Rustfrit stål, etc. Disse materialer indeholder tungmetalelementer, which may cause excessive standards if not handled properly.
For eksempel, the main element of stainless steel contains manganese, krom, og nikkel. To maintain corrosion resistance, rustfrit stål skal indeholde en vis mængde krom. 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, aluminium, og bly. Hvis der ikke er bly, det er svært at danne sig under støbning. Jo højere blyindhold, the easier the casting process is. Derfor, 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.
En anden grund er, at virksomhedens teknologi og udstyr ældes, resulting in the control of trace elements. Som regel, når det nye udstyr først sættes i produktion, dets produkter er kvalificerede, men når udstyret bruges i længere tid, 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. Imidlertid, 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. Dette skyldes, at nogle producenter ikke køber standard messinglegeringer for at kontrollere omkostningerne, 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.
Hvordan man skelner ringere vandhaner fra prisen? 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.
“Sammenlignet med store produkter, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, og vil ikke være opmærksom på problemet med overdreven blyindhold.” A Shanghai resident who is renovating at home told reporters.
I denne forbindelse, 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.
