Investigation of low temperature decomposition process of asbestos using salts

水泥-石棉复合物的分解过程，当盐的少量数量被添加到调查中。最有效的补充剂， CaCl_2，使分解产品的原始材料在C_2SiO_4和CaCl_2的形成中增加了大量的Cl内容。这种化合物是合成的和热的性质是可以测量的。去除实际处理过的材料中的Cl含量很差，因此我们在没有Cl含量和减少处理时间的方法的情况下对分解添加物进行了调查。

The decomposition process of cement-asbestos composites when a small amount of salt is added was investigated. The most effective additive, CaCl_2, makes recycling of decomposed products into raw materials for cement difficult due to increase in Cl content from formation of Ca_2SiO_4・CaCl_2. The compound was synthesized and thermal properties were measured. Removal of Cl content in the actual processed material was difficult, thus we investigated decomposition additives without Cl content and methods to reduce processing time.
