Why is the failure rate of faucets rising?

It is reported that Shanghai has conducted random inspections on the quality of faucets, and the unqualified rate has reached 40%. What causes such a low pass rate of faucets?

This is firstly caused by technological reasons. Ni asiko yi, many daily necessities are made of copper, irin, stainless steel and other materials. Awọn ohun elo wọnyi ni awọn eroja irin ti o wuwo ninu. If they are not handled properly, they may exceed the standard.

Fun apere, the main elements of stainless steel include manganese, chromium, ati nickel. In order to maintain corrosion resistance, irin alagbara, irin gbọdọ ni iye kan ti chromium. 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, aluminiomu, ati asiwaju. Ti ko ba si asiwaju, o jẹ soro lati dagba nigba simẹnti. Awọn ti o ga akoonu asiwaju, the easier the casting process. Nitorina, 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.

Idi miiran ni pe imọ-ẹrọ ile-iṣẹ ati ẹrọ ti ogbo, causing trace elements to be uncontrollable. Nigbagbogbo, nigbati awọn titun ẹrọ ti wa ni akọkọ fi sinu gbóògì, awọn ọja rẹ jẹ oṣiṣẹ, ṣugbọn nigbati awọn ẹrọ ti lo fun igba pipẹ, 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, but some factories continue to use it to save money. This is a technical problem and also a cost problem.

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. Eyi jẹ nitori diẹ ninu awọn aṣelọpọ ko ra awọn alloy idẹ boṣewa lati le ṣakoso awọn idiyele, 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.

Bii o ṣe le ṣe iyatọ awọn faucets ti o kere julọ lati idiyele naa? 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.

“Akawe si tobi awọn ọja, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, ati pe kii yoo san ifojusi si iṣoro ti akoonu asiwaju ti o pọju.” A Shanghai citizen who is decorating his home told reporters.

Ni asopọ pẹlu eyi, 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.
