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. Gaur egun, many daily necessities are made of copper, burdina, stainless steel and other materials. Material hauek metal astunak dituzte. If they are not handled properly, they may exceed the standard.
Adibidez, the main elements of stainless steel include manganese, kromoa, eta nikela. In order to maintain corrosion resistance, altzairu herdoilgaitzak kromo kopuru jakin bat izan behar du. 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, aluminioa, eta beruna. Berunerik ez badago, galdaketan osatzea zaila da. Berun-edukia zenbat eta handiagoa izan, the easier the casting process. Horregatik, 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.
Beste arrazoi bat konpainiaren teknologia eta ekipamendua zahartzen ari direla da, causing trace elements to be uncontrollable. Normalean, ekipo berria lehen aldiz ekoizten denean, bere produktuak sailkatuta daude, baina ekipoa denbora luzez erabiltzen denean, 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. Hau da, fabrikatzaile batzuek ez dituztelako letoizko aleazio estandarrak erosten kostuak kontrolatzeko, 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.
Nola bereizi beheko txorrotak preziotik? 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.
“Produktu handiekin alderatuta, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, eta ez dio gehiegizko berun edukiaren arazoari erreparatuko.” A Shanghai citizen who is decorating his home told reporters.
Alde horretatik, 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.
