Prečo stúpa poruchovosť faucetov?

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. V súčasnosti, many daily necessities are made of copper, železo, stainless steel and other materials. Tieto materiály obsahujú prvky ťažkých kovov. If they are not handled properly, they may exceed the standard.

Napríklad, the main elements of stainless steel include manganese, chróm, a niklu. In order to maintain corrosion resistance, nehrdzavejúca oceľ musí obsahovať určité množstvo chrómu. 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, hliník, a viesť. Ak nie je olovo, pri odlievaní sa ťažko formuje. Čím vyšší je obsah olova, the easier the casting process. Preto, 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.

Ďalším dôvodom je, že technológie a vybavenie spoločnosti starnú, causing trace elements to be uncontrollable. Zvyčajne, pri prvom uvedení nového zariadenia do výroby, jej výrobky sú kvalifikované, ale keď sa zariadenie používa dlhší čas, 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. Je to preto, že niektorí výrobcovia nenakupujú štandardné zliatiny mosadze, aby mali pod kontrolou náklady, 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.

Ako rozlíšiť podradné vodovodné batérie od ceny? 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.

“V porovnaní s veľkými výrobkami, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, a nebude venovať pozornosť problému nadmerného obsahu olova.” A Shanghai citizen who is decorating his home told reporters.

V tomto ohľade, 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.
