ʻI he taimi ni, many daily necessities are made of materials such as copper, ukamea, stainless ukamea, mo e alā meʻa pe. ʻOku ʻi he ngaahi naunau ko ʻeni ha ngaahi ʻelemeniti ukamea mamafa, which may cause excessive standards if not handled properly.
Hange ko ʻeni, the main element of stainless steel contains manganese, chromium, mo e seniti ʻe nima. To maintain corrosion resistance, kuo pau ke ʻi stainless ukamea ha lahi ʻo e chromium. 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, foila, pea taki. Kapau ʻoku ʻikai ke ʻi ai ha taki, ʻOku faingataʻa ke faʻu lolotonga hono laku. Ko e maʻolunga ange ʻa e meʻa ʻi loto, the easier the casting process is. Ko ia, 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.
Ko e ʻuhinga ʻe taha he ʻoku motuʻa e tekinolosia mo e meʻangaue ʻa e kautaha, resulting in the control of trace elements. ʻOku faʻa, ʻi he taimi ʻoku fuofua fokotuʻutuʻu ai ʻa e meʻangaue foʻou, ʻoku feʻunga hono koloa, ka ʻi he taimi ʻoku fakaʻaongaʻi ai ʻa e meʻangāué ʻi ha taimi lōloa, 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. Neongo ia, 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. ʻOku tupu ʻeni he ʻoku ʻi ai ha niʻihi ʻoku ʻikai ke nau fakatau ʻa e alloys palasa angamaheni kae lava ke mapuleʻi ʻa e fakamole, 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.
Founga hono fakafaikehekeheʻi ʻo e paipa vai maʻulalo mei he totongi? Some insiders told reporters that a copper faucet with a formal process should cost more than 100 ʻIuani, while tens of faucets are likely to use lead brass.
“Fakafehoanaki ki he ngaahi koloa lalahi, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, pea he ʻikai ke ne tokanga ki he palopalema ʻo e fuʻu totuʻa ʻa e meʻa ʻoku tataki.” A Shanghai resident who is renovating at home told reporters.
ʻI he meʻa ni, 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.
