磷酸盐作为粘结剂,已在粘结剂工业中自成一个体系。它耐高温、耐热冲击、耐腐蚀,可望在铸造生产中得到有效利用。 本文详述磷酸盐的粘结机理,分析其在铸造过程中作为粘结剂使用的可能性和碍障。并根据苏联关于钙—铝—铬磷酸盐用于熔模铸造的报导,介绍实验室配制钙—铝—铬、铝—铬磷酸盐的有效方法。 Phosphate as a binder has been a system in the binder industry. It is high temperature, heat shock, corrosion resistance, is expected to be effective in the casting production. This article details the bonding mechanism of phosphates and analyzes the possibilities and obstacles of using them as binders in the casting process. According to the report of the Soviet Union on calcium-aluminum-chromium phosphates for investment casting, an effective method of preparing calcium-aluminum-chromium and aluminum-chromium phosphates in laboratories was introduced.
