فی الحال, many daily necessities are made of materials such as copper, لوہا, سٹینلیس سٹیل, وغیرہ. ان مواد میں بھاری دھاتی عناصر ہوتے ہیں۔, which may cause excessive standards if not handled properly.
مثال کے طور پر, the main element of stainless steel contains manganese, کرومیم, اور نکل. To maintain corrosion resistance, سٹینلیس سٹیل میں کرومیم کی ایک خاص مقدار ہونی چاہیے۔. 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, ایلومینیم, اور قیادت. اگر کوئی لیڈ نہیں ہے۔, کاسٹنگ کے دوران تشکیل دینا مشکل ہے۔. لیڈ کا مواد جتنا زیادہ ہوگا۔, the easier the casting process is. اس لیے, 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.
ایک اور وجہ یہ ہے کہ کمپنی کی ٹیکنالوجی اور آلات عمر رسیدہ ہیں۔, resulting in the control of trace elements. عام طور پر, جب نیا سامان پہلی بار پیداوار میں ڈالا جاتا ہے۔, اس کی مصنوعات اہل ہیں۔, لیکن جب سامان طویل عرصے تک استعمال ہوتا ہے۔, 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. البتہ, 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. اس کی وجہ یہ ہے کہ کچھ مینوفیکچررز لاگت کو کنٹرول کرنے کے لیے معیاری پیتل کے مرکب نہیں خریدتے ہیں۔, 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.
قیمت سے کمتر ٹونٹی کو کیسے الگ کیا جائے۔? Some insiders told reporters that a copper faucet with a formal process should cost more than 100 یوآن, while tens of faucets are likely to use lead brass.
“بڑی مصنوعات کے مقابلے میں, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, اور ضرورت سے زیادہ لیڈ مواد کے مسئلے پر توجہ نہیں دیں گے۔” A Shanghai resident who is renovating at home told reporters.
اس سلسلے میں, 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.
