VIGA takes you to reveal the faucet behind the failure rate.

現在のところ, many daily necessities are made of materials such as copper, 鉄, ステンレス鋼, 等. これらの材料には重金属元素が含まれています, which may cause excessive standards if not handled properly.

例えば, the main element of stainless steel contains manganese, クロム, そしてニッケル. To maintain corrosion resistance, ステンレス鋼には一定量のクロムが含まれている必要があります. 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, アルミニウム, そしてリードする. リードがない場合, 鋳造時に成形するのが難しい. 鉛の含有量が多いほど, the easier the casting process is. したがって, 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.

もう一つの理由は、自社の技術や設備の老朽化です。, resulting in the control of trace elements. いつもの, 新しい装置が最初に生産されるとき, その製品は認定されています, しかし、装置を長期間使用すると、, 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. しかし, 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. これは、一部のメーカーがコストを抑えるために標準の黄銅合金を購入していないためです。, 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.

粗悪な蛇口を価格から見分ける方法? 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.

“大型商品と比べて, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, そして過剰な鉛含有量の問題には注意を払わないでしょう。” A Shanghai resident who is renovating at home told reporters.

この点について, 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.
