VIGA帶你揭秘故障率背後的水龍頭.

現在, many daily necessities are made of materials such as copper, 鐵, 不銹鋼, ETC. 這些材料含有重金屬元素, which may cause excessive standards if not handled properly.

例如, the main element of stainless steel contains manganese, 鉻, 和鎳. To maintain corrosion resistance, 不銹鋼必須含有一定量的鉻. If the chromium is not handled properly, it may lead to excessive chromium. 相似地, 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, 鋁, 並領導. 如果沒有鉛, 鑄造時很難成型. 鉛含量越高, the easier the casting process is. 所以, 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.

另一個原因是公司技術和設備老化, resulting in the control of trace elements. 通常, 新設備首次投產時, 其產品合格, 但當設備長時間使用時, 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. 然而, 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. 這是因為有些廠家為了控製成本，不購買標準的黃銅合金, 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.

如何從價格上辨別劣質水龍頭? Some insiders told reporters that a copper faucet with a formal process should cost more than 100 元, while tens of faucets are likely to use lead brass.

“與大型產品相比, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, 也不會去關注鉛含量超標的問題。” A Shanghai resident who is renovating at home told reporters.

對此, 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.
