Ing saiki, many daily necessities are made of materials such as copper, wesi, baja tahan karat, lsp. Bahan kasebut ngemot unsur logam abot, which may cause excessive standards if not handled properly.
Contone, the main element of stainless steel contains manganese, kromium, lan nikel. To maintain corrosion resistance, stainless steel kudu ngemot jumlah tartamtu saka kromium. If the chromium is not handled properly, it may lead to excessive chromium. Semono uga, improper handling of manganese may result in excessive manganese.
The copper alloy used to make the faucet contains trace amounts of metal elements such as iron, alumunium, lan timbal. Yen ora ana timbal, iku angel kanggo mbentuk sak casting. Sing luwih dhuwur isi timbal, the easier the casting process is. Mulane, the copper faucet on the market generally contains a certain amount of lead. If the lead-free process is not done well when the factory is manufactured, it will lead to excessive lead.
Alasan liyane yaiku teknologi lan peralatan perusahaan saya tuwa, resulting in the control of trace elements. Biasane, nalika peralatan anyar pisanan sijine menyang produksi, produk sawijining qualified, nanging nalika piranti digunakake kanggo dangu, the trace elements of the product will exceed the standard. This situation cannot be repaired from a technical point of view, and only new equipment can be replaced. Nanging, some factories continue to use it in order to save money. This is a technical problem and a cost issue.
A bathroom equipment seller told reporters that most of the faucets on the market today are copper cores, but the quality is not good. Small manufacturers, cheap faucets, the possibility of lead exceeding the standard is very large. Iki amarga sawetara manufaktur ora tuku wesi kuningan standar kanggo ngontrol biaya, but purchase cheap lead brass from small workshops as raw materials. This lead brass is often high in lead but at half the price of brass alloy.
Carane mbedakake faucets inferior saka rega? Some insiders told reporters that a copper faucet with a formal process should cost more than 100 yuan, while tens of faucets are likely to use lead brass.
“Dibandhingake karo produk gedhe, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, lan ora bakal menehi perhatian marang masalah isi timbal sing berlebihan.” A Shanghai resident who is renovating at home told reporters.
Ing babagan iki, some insiders said that domestic consumers pay insufficient attention to the quality and safety of faucets, which also makes many unqualified inferior faucets have opportunities.
