Ar hyn o bryd, many daily necessities are made of copper, haearn, stainless steel and other materials. Mae'r deunyddiau hyn yn cynnwys elfennau metel trwm. If they are not handled properly, they may exceed the standard.
Er enghraifft, the main elements of stainless steel include manganese, cromiwm, a nicel. In order to maintain corrosion resistance, rhaid i ddur di-staen gynnwys rhywfaint o gromiwm. If the chromium is handled improperly, it may cause excessive chromium. In the same way, improper handling of manganese may lead to excessive manganese.
The copper alloy used to make faucets contains traces of metal elements such as iron, alwminiwm, ac arwain. Os nad oes plwm, mae'n anodd ei ffurfio yn ystod castio. Po uchaf yw'r cynnwys arweiniol, the easier the casting process. Felly, copper faucets on the market generally contain a certain amount of lead. If the factory does not do a good job of removing lead during manufacturing, it will cause excessive lead.
Rheswm arall yw bod technoleg ac offer y cwmni yn heneiddio, causing trace elements to be uncontrollable. Fel arfer, pan fydd yr offer newydd yn cael ei gynhyrchu gyntaf, ei gynhyrchion yn gymwys, ond pan ddefnyddir yr offer am amser hir, the products will exceed the trace elements. This situation cannot be repaired from a technical point of view and can only be replaced with new equipment. Fodd bynnag, some factories continue to use them in order to save money. This is a technical and cost issue.
A seller of bathroom equipment told reporters that most faucets on the market now have copper cores, but the quality varies. Faucets from small manufacturers and cheaper prices are likely to exceed the lead. Mae hyn oherwydd nad yw rhai gweithgynhyrchwyr yn prynu aloion pres safonol er mwyn rheoli costau, but purchase cheap lead brass as raw materials from small workshops. This kind of lead brass tends to have a high lead content, but the price is only half of the brass alloy.
Sut i wahaniaethu faucets israddol o'r pris? An industry insider told reporters that a copper faucet with formal craftsmanship should cost more than one hundred yuan, while a faucet worth tens of yuan is likely to use lead brass.
“O'i gymharu â chynhyrchion mawr, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, ac ni fydd yn rhoi sylw i broblem cynnwys plwm gormodol.” A Shanghai citizen who is decorating his home told reporters.
Yn hyn o beth, some people in the industry said that domestic consumers did not pay enough attention to the quality and safety of faucets, which also gave many unqualified and low-quality faucets an opportunity.
