It is reported that Shanghai has conducted random inspections on the quality of faucets, and the unqualified rate has reached 40%. What causes such a low pass rate of faucets?
This is firstly caused by technological reasons. Sa kasalukuyan, many daily necessities are made of copper, bakal, stainless steel and other materials. Ang mga materyales na ito ay naglalaman ng mabibigat na elemento ng metal. If they are not handled properly, they may exceed the standard.
Halimbawa, the main elements of stainless steel include manganese, Chromium, at nikel. In order to maintain corrosion resistance, Ang hindi kinakalawang na asero ay dapat maglaman ng isang tiyak na halaga ng kromo. 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, aluminyo, at tingga. Kung walang tingga, Mahirap na mabuo sa panahon ng paghahagis. Ang mas mataas na nilalaman ng tingga, the easier the casting process. Samakatuwid, 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.
Ang isa pang kadahilanan ay ang teknolohiya at kagamitan ng kumpanya ay tumatanda, causing trace elements to be uncontrollable. Karaniwan, Kapag ang bagong kagamitan ay unang inilalagay sa paggawa, Ang mga produkto nito ay kwalipikado, Ngunit kapag ang kagamitan ay ginagamit nang mahabang panahon, 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, but some factories continue to use it to save money. This is a technical problem and also a cost problem.
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. Ito ay dahil ang ilang mga tagagawa ay hindi bumili ng karaniwang mga haluang metal na tanso upang makontrol ang mga gastos, 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.
Paano makilala ang mga mas mababang mga gripo mula sa presyo? 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.
“Kumpara sa malalaking produkto, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, at hindi bibigyan ng pansin ang problema ng labis na nilalaman ng tingga.” A Shanghai citizen who is decorating his home told reporters.
Kaugnay nito, 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.
