Trenutno, many daily necessities are made of materials such as copper, gvožđe, nerđajući čelik, itd. Ovi materijali sadrže elemente teških metala, which may cause excessive standards if not handled properly.
Na primjer, the main element of stainless steel contains manganese, hrom, i nikla. To maintain corrosion resistance, nehrđajući čelik mora sadržavati određenu količinu hroma. If the chromium is not handled properly, it may lead to excessive chromium. Slično, 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, aluminijum, i olovo. Ako nema olova, teško se formira tokom livenja. Što je veći sadržaj olova, the easier the casting process is. Stoga, 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.
Drugi razlog je to što tehnologija i oprema kompanije stari, resulting in the control of trace elements. Obično, kada je nova oprema prvi put puštena u proizvodnju, njegovi proizvodi su kvalifikovani, ali kada se oprema koristi duže vrijeme, 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. kako god, 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. To je zato što neki proizvođači ne kupuju standardne legure mesinga kako bi kontrolirali troškove, 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.
Kako razlikovati inferiorne slavine od cijene? 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.
“U poređenju sa velikim proizvodima, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, i neće obraćati pažnju na problem prekomjernog sadržaja olova.” A Shanghai resident who is renovating at home told reporters.
U tom pogledu, 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.
