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. Aktualisht, many daily necessities are made of copper, hekuri, stainless steel and other materials. Këto materiale përmbajnë elemente metalike të rënda. If they are not handled properly, they may exceed the standard.
Për shembull, the main elements of stainless steel include manganese, kromi, dhe nikelit. In order to maintain corrosion resistance, çelik inox duhet të përmbajë një sasi të caktuar kromi. 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, alumini, dhe plumbi. Nëse nuk ka plumb, është e vështirë të formohet gjatë derdhjes. Sa më e lartë të jetë përmbajtja e plumbit, the easier the casting process. Prandaj, 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.
Një arsye tjetër është se teknologjia dhe pajisjet e kompanisë po plaken, causing trace elements to be uncontrollable. Zakonisht, kur pajisja e re vihet për herë të parë në prodhim, produktet e saj janë të kualifikuara, por kur pajisja përdoret për një kohë të gjatë, 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. Kjo për shkak se disa prodhues nuk blejnë lidhje standarde prej bronzi për të kontrolluar kostot, 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.
Si të dalloni rubinetat inferiore nga çmimi? 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.
“Krahasuar me produktet e mëdha, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, dhe nuk do t'i kushtojë vëmendje problemit të përmbajtjes së tepërt të plumbit.” A Shanghai citizen who is decorating his home told reporters.
Në këtë drejtim, 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.
