摘　　要：研究稀土稳定剂加入量对钙锌/稀土复合稳定体系热稳定效果的影响。结果表明:复合稳定体系的热稳定性能比单一的钙锌稳定剂稳定效果有很大提高,在稀土稳定剂用量为3.5份时,复合稳定体系的稳定效果最佳。Influences of the adding amount of rare- earth stabilizer in the Ca - Zn/rare- earth compound stabilizer on the thermal stabilization effects were studied. The results showed that the thermal stability of the complex stabilization system was greatly improved as compared with a single Ca- Zn stabilizer,and the best stabilization effects could be obtained when 3.5 parts of rare- earth stabilizer were used in the complex stabilization system.
