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

Šiuo metu, many daily necessities are made of materials such as copper, geležies, nerūdijančio plieno, ir tt. Šiose medžiagose yra sunkiųjų metalų elementų, which may cause excessive standards if not handled properly.

Pavyzdžiui, the main element of stainless steel contains manganese, Chromas, ir nikelio. To maintain corrosion resistance, nerūdijančiame pliene turi būti tam tikras chromo kiekis. 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, aliuminio, ir švino. Jei švino nėra, liejant sunkiai susidaro. Kuo didesnis švino kiekis, the easier the casting process is. Todėl, 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.

Kita priežastis – įmonės technologijos ir įranga sensta, resulting in the control of trace elements. Paprastai, kai nauja įranga pirmą kartą pradedama gaminti, jos produktai yra kvalifikuoti, bet kai įranga naudojama ilgą laiką, 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. Tačiau, 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. Taip yra todėl, kad kai kurie gamintojai neperka standartinių žalvario lydinių, kad galėtų kontroliuoti išlaidas, 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.

Kaip atskirti prastesnius maišytuvus nuo kainos? Some insiders told reporters that a copper faucet with a formal process should cost more than 100 juanių, while tens of faucets are likely to use lead brass.

“Palyginti su dideliais gaminiais, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, ir nekreips dėmesio į per didelio švino turinio problemą.” A Shanghai resident who is renovating at home told reporters.

Šiuo atžvilgiu, 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.
