አህነ, many daily necessities are made of copper, ብረት, stainless steel and other materials. እነዚህ ቁሳቁሶች ከባድ የብረት ንጥረ ነገሮችን ይይዛሉ. If they are not handled properly, they may exceed the standard.
ለምሳሌ, the main elements of stainless steel include manganese, ክሮሚየም, እና ኒኬል. In order to maintain corrosion resistance, አይዝጌ አረብ ብረት የተወሰነ የ Chromium መጠን መያዝ አለበት. 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, አሉሚኒየም, እና ይመራሉ. መሪ ከሌለ, በመሸሽ ወቅት ለመቅረጽ አስቸጋሪ ነው. የመሪነት ይዘት ከፍ ያለ ይዘት, the easier the casting process. ስለዚህ, 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.
ሌላኛው ምክንያት የኩባንያው ቴክኖሎጂ እና መሳሪያዎች እርጅና ናቸው, causing trace elements to be uncontrollable. አብዛኛውን ጊዜ, አዲሱ መሣሪያዎች ለመጀመሪያ ጊዜ በማምረት ውስጥ ሲገባ, ምርቶቹ ብቁ ናቸው, ነገር ግን መሣሪያው ለረጅም ጊዜ ጥቅም ላይ ሲውል, 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. ቢሆንም, some factories continue to use them in order to save money. This is a technical and cost issue.
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. ይህ የሆነበት ምክንያት አንዳንድ አምራቾች ወጪዎችን ለመቆጣጠር መደበኛ የናስ መድኃኒቶችን ስለገዙ ነው, 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.
ከድዋይ በታች የሆኑ ጥቃቅን ነገሮችን እንዴት መለየት እንደሚቻል? 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.
“ከትላልቅ ምርቶች ጋር ሲነፃፀር, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, እና ከመጠን በላይ የመሪነት ይዘት ችግር ትኩረት አይሰጥም.” A Shanghai citizen who is decorating his home told reporters.
በዚህ ረገድ, 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.
