摘要
介绍了我国硬聚氯乙烯给水管材配方体系的沿革,从国家标准导向、加工性、经济性等方面对铅盐、钙锌、有机锡、稀土配方体系进行了分析比较,并对铅盐配方体系的转换方向提出了建议。
Course of change and development of formula systems for unplasticized polyvinyl chloride pipes for water supply is described. Comparison and analysis of lead-based stabilizer, Ca-Zn compounded stabilizer, organotin-rare-earth compounded stabilizer are carded out with regard to national standard guidance, processing and economic benefits. Proposal for change orientation of lead-based stabilizer is presented.
