水表壳铜铸件的铅析出问题探讨

Pb Precipitation in the Water Watch Copper Castings

随着社会的进步,环境意识的增强,水表作为涉及饮用水卫生安全有关的产品引起了人们的关注。通过分析水表行业当前表壳材料的使用状况,针对面临的困惑和问题,提出了几条建议:开展水表涉水零部件金属材料浸泡后元素溶出的研究,开展涉水零部件无毒、无污染、无生物活性的新材料、新防护材料和涉水零部件制造新工艺的研究,制订、修订相关标准与先进国家相关标准接轨等。

With the social development and the raising environmental awareness, it appears to be more and more important for people to be conscious about their own health and safety. The attention towards the water meter, which is closely relevant to the hygiene of drinking water, as well as how to face this issue properly, are the main projects of the article. It also proposes several suggestions to the difficult problems by analysing the current situation of using existing case material of the water metre.
