إزالة الغموض عن السبب وراء زيادة معدل فشل الحنفيات

في الوقت الحالي, many daily necessities are made of copper, حديد, stainless steel and other materials. تحتوي هذه المواد على عناصر معدنية ثقيلة. If they are not handled properly, they may exceed the standard.

على سبيل المثال, the main elements of stainless steel include manganese, الكروم, والنيكل. In order to maintain corrosion resistance, يجب أن يحتوي الفولاذ المقاوم للصدأ على كمية معينة من الكروم. 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, الألومنيوم, والرصاص. إذا لم يكن هناك الرصاص, من الصعب أن تتشكل أثناء الصب. كلما زاد محتوى الرصاص, the easier the casting process. لذلك, 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.

سبب آخر هو أن تكنولوجيا الشركة ومعداتها أصبحت قديمة, causing trace elements to be uncontrollable. عادة, عندما يتم وضع المعدات الجديدة في الإنتاج لأول مرة, منتجاتها مؤهلة, ولكن عندما يتم استخدام المعدات لفترة طويلة, 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. لكن, 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. وذلك لأن بعض الشركات المصنعة لا تشتري سبائك النحاس القياسية من أجل التحكم في التكاليف, 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.

كيفية التمييز بين الحنفيات الرديئة والسعر? 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.

“بالمقارنة مع المنتجات الكبيرة, faucets worth tens of yuan are really not worth spending so much time and energy to choose one by one, ولن ينتبه لمشكلة المحتوى الزائد من الرصاص.” A Shanghai citizen who is decorating his home told reporters.

في هذا الصدد, 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.
