Why is the failure rate of faucets rising?

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. Ayni paytda, many daily necessities are made of copper, temir, stainless steel and other materials. Ushbu materiallarda og'ir metall elementlar mavjud. If they are not handled properly, they may exceed the standard.

Masalan, the main elements of stainless steel include manganese, xrom, va nikel. In order to maintain corrosion resistance, Zanglamaydigan po'latda ma'lum miqdorda xrom bo'lishi kerak. 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, alyuminiy, va etakchilik. Agar qo'rg'oshin bo'lmasa, quyish paytida shakllanish qiyin. Qo'rg'oshin tarkibi qanchalik yuqori bo'lsa, the easier the casting process. Shuning uchun, 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.

Yana bir sabab shundaki, kompaniya texnologiyalari va uskunalari qarish, causing trace elements to be uncontrollable. Odatda, Yangi uskunalar birinchi bo'lib ishlab chiqarishga kiritilganda, Uning mahsulotlari malakali, Ammo uskunalar uzoq vaqt davomida ishlatilganda, 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. Buning sababi, ba'zi ishlab chiqaruvchilar xarajatlarni nazorat qilish uchun standart shtat qotishmalarini sotib olmaydilar, 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.

Narxdan past kamerani qanday ajratish kerak? 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.

“Katta mahsulotlar bilan taqqoslaganda, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, va haddan tashqari qo'rg'oshin tarkibiga e'tibor bermaydi.” A Shanghai citizen who is decorating his home told reporters.

Ushbu munosabatda, 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.
