中文摘要: 覆铜板废边角料是一种具有明显“高硼低铁”特征的电子废料,为获得适合覆铜板废边角料回收工艺的黏度特性,用分析纯化学试剂配制合成覆铜板废边角料熔炼渣,采用RTW-10型熔体综合物性测定仪测定熔炼渣的黏度,并探索了FeO含量( )、Fe3O4含量( )、Al2O3含量( )、B2O3含量( )及钙硅比( )等炉渣组成对黏度的影响规律。结果表明,熔炼渣黏度随熔炼温度T、 、 和 增大而减小;随 或 增大而增大;在工业生产熔炼温度下(1 100~1 200 ℃),黏度在0.1~0.5 Pa?s之间波动,流动性较好,能满足冶炼要求。

Abstract:Copper clad laminate scrap (CCLS) is a kind of electronic waste containing low iron and high boron. To get suitable viscosity property for CCLS recycling process, several smelting slags were prepared with analysis pure chemical reagent and their viscosities were measured with RTW-10 synthetic test instrument through rotating cylinder method. Effects of , , , ,and on viscosity were investigated. The results show that viscosity of smelting slag rises with increase of and , and drops with increase of T, , and . Under actual industrial melting temperature (1 100-1 200 ℃), viscosity fluctuates within 0.1-0.5 Pa?s, which can meet the smelting requirements.
