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. Am Moment, many daily necessities are made of copper, Eisen, stainless steel and other materials. Dës Materialien enthalen schwéier Metal Elementer. If they are not handled properly, they may exceed the standard.
Zum Beispill, the main elements of stainless steel include manganese, chrom, an Néckel. In order to maintain corrosion resistance, Edelstol muss eng gewësse Quantitéit Chrom enthalen. 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, Aluminium, a Féierung. Wann et kee Lead ass, et ass schwéier ze bilden während dem Casting. Wat méi héich ass de Bläi Inhalt, the easier the casting process. Dofir, 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.
En anere Grond ass datt d'Technologie an d'Ausrüstung vun der Firma alternd sinn, causing trace elements to be uncontrollable. Normalerweis, wann déi nei Ausrüstung fir d'éischt a Produktioun gesat gëtt, seng Produkter sinn qualifizéiert, mee wann d'Ausrüstung fir eng laang Zäit benotzt gëtt, 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. Dëst ass well e puer Hiersteller keng Standard Messinglegierungen kafen fir d'Käschte ze kontrolléieren, 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.
Wéi ënnerscheeden schlëmmen faucets aus dem Präis? 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.
“Am Verglach mat grousse Produkter, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, a wäert net op de Problem vum exzessive Leadinhalt oppassen.” A Shanghai citizen who is decorating his home told reporters.
An dëser Hisiicht, 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.
