iVIGA Tap Factory Verskaffer
Huidiglik, many daily necessities are made of materials such as copper, strykyster, vleklose staal, ens. Hierdie materiale bevat swaar metaalelemente, which may cause excessive standards if not handled properly.
Byvoorbeeld, the main element of stainless steel contains manganese, chroom, en nikkel. To maintain corrosion resistance, vlekvrye staal moet 'n sekere hoeveelheid chroom bevat. If the chromium is not handled properly, it may lead to excessive chromium. Net so, 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, aluminium, en lei. As daar geen lood is nie, dit is moeilik om te vorm tydens giet. Hoe hoër die loodinhoud, the easier the casting process is. Daarom, 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.
Nog 'n rede is dat die maatskappy se tegnologie en toerusting verouder, resulting in the control of trace elements. Gewoonlik, wanneer die nuwe toerusting die eerste keer in produksie geplaas word, sy produkte is gekwalifiseer, maar wanneer die toerusting vir 'n lang tyd gebruik word, 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. Egter, 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. Dit is omdat sommige vervaardigers nie standaard koperlegerings koop om koste te beheer nie, 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.
Hoe om minderwaardige krane van die prys te onderskei? 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.
“In vergelyking met groot produkte, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, en sal nie aandag gee aan die probleem van oormatige loodinhoud nie.” A Shanghai resident who is renovating at home told reporters.
In hierdie verband, 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.
