Hal hazırda, many daily necessities are made of materials such as copper, dəmir, paslanmayan polad, və s. Bu materiallarda ağır metal elementləri var, which may cause excessive standards if not handled properly.
Misal üçün, the main element of stainless steel contains manganese, xrom, və nikel. To maintain corrosion resistance, paslanmayan poladda müəyyən miqdarda xrom olmalıdır. If the chromium is not handled properly, it may lead to excessive chromium. Eynilə, 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, alüminium, və rəhbərlik edir. Qurğuşun yoxdursa, tökmə zamanı formalaşması çətindir. Qurğuşun tərkibi nə qədər yüksəkdir, the easier the casting process is. Buna görə də, 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.
Digər səbəb isə şirkətin texnologiya və avadanlıqlarının köhnəlməsidir, resulting in the control of trace elements. Adətən, yeni avadanlıq ilk dəfə istehsala buraxıldıqda, onun məhsulları keyfiyyətlidir, lakin avadanlıq uzun müddət istifadə edildikdə, 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. Lakin, 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. Bunun səbəbi, bəzi istehsalçıların xərcləri nəzarət etmək üçün standart pirinç ərintiləri almamasıdır, 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.
Aşağı keyfiyyətli kranları qiymətdən necə ayırd etmək olar? 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.
“Böyük məhsullarla müqayisədə, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, və həddindən artıq qurğuşun məzmunu probleminə diqqət yetirməyəcək.” A Shanghai resident who is renovating at home told reporters.
Bu mövzuda, 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.
