我厂自建厂以来,一直使用石蜡、硬脂酸模料,尽管这种低温模料经电解处理,能充分回用,但炎夏易软化变形,同时不适应硅溶胶制亮新工艺发展的需要,为此我厂研究试验出一种热稳定性高,化学稳定性好,不易沾污的中温模料,经近一年的试生产考验,证明是一种经济适用的好模料。一、原材料的选择 Since the establishment of our factory, we have been using paraffin and stearic acid molds. Although this kind of low-temperature mold material can be fully reused after being electrolyzed, it can soften and deform in summer and not meet the needs of the development of the bright and new process of silica sol. To this end, I plant to test a high thermal stability, good chemical stability, not easy to stain in the temperature mold, after nearly a year of trial production test proves to be an economical and good mold. First, the choice of raw materials
