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. Šobrīd, many daily necessities are made of copper, dzelzs, stainless steel and other materials. Šie materiāli satur smago metālu elementus. If they are not handled properly, they may exceed the standard.
Piemēram, the main elements of stainless steel include manganese, hroms, un niķelis. In order to maintain corrosion resistance, nerūsējošajam tēraudam jābūt noteiktam hroma daudzumam. 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, alumīnija, un svinu. Ja nav svina, ir grūti veidot liešanas laikā. Jo lielāks svina saturs, the easier the casting process. Tāpēc, 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.
Vēl viens iemesls ir uzņēmuma tehnoloģiju un aprīkojuma novecošanās, causing trace elements to be uncontrollable. Parasti, kad jaunā iekārta pirmo reizi tiek nodota ražošanā, tās produkti ir kvalificēti, bet kad iekārta tiek lietota ilgstoši, 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. Tas ir tāpēc, ka daži ražotāji nepērk standarta misiņa sakausējumus, lai kontrolētu izmaksas, 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.
Kā atšķirt zemākas kvalitātes jaucējkrānus no cenas? 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.
“Salīdzinājumā ar lieliem produktiem, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, un nepievērsīs uzmanību pārmērīga svina satura problēmai.” A Shanghai citizen who is decorating his home told reporters.
Šajā sakarā, 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.
