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. Во моментов, many daily necessities are made of copper, железо, stainless steel and other materials. Овие материјали содржат тешки метални елементи. If they are not handled properly, they may exceed the standard.
На пример, the main elements of stainless steel include manganese, хром, и никел. In order to maintain corrosion resistance, нерѓосувачкиот челик мора да содржи одредена количина на хром. 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, алуминиум, и олово. Ако нема олово, тешко е да се формира за време на лиење. Колку е поголема содржината на олово, the easier the casting process. Затоа, 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.
Друга причина е што технологијата и опремата на компанијата стареат, causing trace elements to be uncontrollable. Вообичаено, кога новата опрема за прв пат ќе биде пуштена во производство, нејзините производи се квалификувани, но кога опремата се користи подолго време, 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. Тоа е затоа што некои производители не купуваат стандардни легури од месинг со цел да ги контролираат трошоците, 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.
Како да разликувате инфериорни славини од цената? 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.
“Во споредба со големите производи, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, и нема да обрнува внимание на проблемот со прекумерната содржина на олово.” A Shanghai citizen who is decorating his home told reporters.
Во овој поглед, 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.
