目前,国内熔模铸造所应用的模料,主要是石蜡、硬脂酸。这种模料由于硬脂酸是由动植物油加工制成的,不但阶格昂贵,而且资源缺乏。经常出现供不应求的现象,成为正常生产和进一步发展生产的主要障碍。同时,这种模料软化点低,强度差,不能满足交替硬化制壳新工艺的要求。为解决这 At present, the mold used in domestic investment casting, mainly paraffin, stearic acid. Since this stearic acid is made from animal and vegetable oils, stearic acid is not only expensive but also lacking in resources. Often the phenomenon of short supply has become a major obstacle to the normal production and further development of production. At the same time, the low softening point of this material, the strength is poor, can not meet the requirements of alternative hardening shell process. To solve this
