我厂熔模铸造采用氯化钙做制壳硬化剂,用此新工艺已生产出合格铸钢件十四个品种一万多件。下面就氯化钙的有关问题作简要介绍。一、氯化钙的性能氯化钙是氨碱法的付产物,可由碳酸钙和盐酸作用结晶而制得。通常用作脱水剂、食物保存剂、防冻剂等。其分子式有CaCl_2、CaCl_2、H_2O、CaCl_2·2H_2O、CaCl_2·6H_2四种,市面上出售的只分无水的和含水的两类。熔模
I plant investment casting using calcium chloride as shell hardener, with this new technology has produced qualified castings fourteen varieties of more than 10,000 pieces. Below on the calcium chloride related issues for a brief introduction. First, the performance of calcium chloride Calcium chloride is a byproduct of ammonia-alkali law, by the role of calcium carbonate and hydrochloric acid crystallization obtained. Usually used as a dehydrating agent, food preservative, antifreeze and so on. Its molecular formula CaCl 2, CaCl 2, H 2 O, CaCl 2 · 2H 2 O, CaCl 2 · 6H 2 four kinds of available on the market only divided into two types of anhydrous and aqueous. Fused
