iVIGA Tap Factory Kaiwhakarato
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. I tenei wa, many daily necessities are made of copper, haeana, stainless steel and other materials. Ko enei taonga kei roto i nga waahanga whakarewa taumaha. If they are not handled properly, they may exceed the standard.
Hei tauira, the main elements of stainless steel include manganese, numoana, me te nickel. In order to maintain corrosion resistance, Ko te kowiri tira me whakauru he nui o te kromium. 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, konumohe, me te arahi. Mena kaore he ara, He uaua te hanga i te wa e tukuna ana. Ko te nui ake o te kaupapa matua, the easier the casting process. No reira, 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.
Ko tetahi atu take ko te hangarau hangarau me nga taputapu a te kamupene he pakeke, causing trace elements to be uncontrollable. Ko te tikanga, A, no te mea ka tukuna tuatahi nga taputapu hou ki roto, Ko ona hua he tohu, Engari ka whakamahia nga taputapu mo te wa roa, 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. Na te mea kaore etahi o nga kaihanga e hoko i nga paerewa paerewa kia pai ai te whakahaere i nga utu, 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.
Me pehea te wehe i nga tiihi ngoikore mai i te utu? 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.
“Whakaritea ki nga hua nui, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, e kore ano e aro ki te raru o te ihirangi arahi nui.” A Shanghai citizen who is decorating his home told reporters.
Mo tenei whakaaro, 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.
