VIGA te duce să dezvălui robinetul din spatele ratei de eșec.

În prezent, many daily necessities are made of materials such as copper, fier, oţel inoxidabil, etc. Aceste materiale conțin elemente metalice grele, which may cause excessive standards if not handled properly.

De exemplu, the main element of stainless steel contains manganese, crom, și nichel. To maintain corrosion resistance, oțelul inoxidabil trebuie să conțină o anumită cantitate de crom. 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, aluminiu, și plumb. Dacă nu există plumb, se formează greu în timpul turnării. Cu cât este mai mare conținutul de plumb, the easier the casting process is. Prin urmare, 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.

Un alt motiv este că tehnologia și echipamentele companiei sunt îmbătrânite, resulting in the control of trace elements. De obicei, atunci când noul echipament este prima dată în producție, produsele sale sunt calificate, dar când echipamentul este folosit mult timp, 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. Cu toate acestea, 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. Acest lucru se datorează faptului că unii producători nu cumpără aliaje standard de alamă pentru a controla costurile, 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.

Cum să distingem robinetele inferioare de preț? Some insiders told reporters that a copper faucet with a formal process should cost more than 100 yuan, while tens of faucets are likely to use lead brass.

“Comparativ cu produsele mari, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, și nu va acorda atenție problemei conținutului excesiv de lead-uri.” A Shanghai resident who is renovating at home told reporters.

În această privinţă, 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.
