用多种现代测试方法,分析研究了三元乙丙橡胶Keltan312和Keltan378的十一种胶料及俄产СКЭПТ-50橡胶在模压硫化和模型模压硫化中在模具上形成污垢的原因及影响因素。胶料中的增塑剂和浅色填料是生成污垢的重要原因。胶料工艺参数及组成对污垢的组成没有影响,但影响其生成的速率。
A variety of modern test methods were used to analyze the causes and influencing factors of the formation of fouling on the mold during the eleven kinds of rubber compounds of Keltan312 and Keltan378 and the Russian-made СКЭПТ-50 rubber in the molding vulcanization and molding press vulcanization. Plasticizers and light-colored filler plastic filler is an important reason to generate dirt. Rubber processing parameters and composition of the composition of the dirt has no effect, but affect the rate of its generation.
