Pada masa ini, many daily necessities are made of materials such as copper, besi, keluli tahan karat, dan lain-lain. Bahan ini mengandungi unsur logam berat, which may cause excessive standards if not handled properly.
Sebagai contoh, the main element of stainless steel contains manganese, Chromium, dan nikel. To maintain corrosion resistance, Keluli tahan karat mesti mengandungi sejumlah kromium. If the chromium is not handled properly, it may lead to excessive chromium. Similarly, 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, aluminium, dan memimpin. Sekiranya tidak ada petunjuk, sukar dibentuk semasa pemutus. Semakin tinggi kandungan plumbum, the easier the casting process is. Oleh itu, 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.
Sebab lain ialah teknologi dan peralatan syarikat sedang menua, resulting in the control of trace elements. Biasanya, Apabila peralatan baru mula -mula dimasukkan ke dalam pengeluaran, Produknya layak, Tetapi apabila peralatan digunakan untuk masa yang lama, 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. Namun begitu, 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. Ini kerana sesetengah pengeluar tidak membeli aloi tembaga standard untuk mengawal kos, 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.
Cara membezakan keran yang lebih rendah dari harga? 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.
“Berbanding dengan produk besar, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, dan tidak akan memberi perhatian kepada masalah kandungan plumbum yang berlebihan.” A Shanghai resident who is renovating at home told reporters.
Dalam hal ini, 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.
