| 摘 要： | 通过对4种试样初始粘度和可使用时间的测定，发现氧化铝晶粒太细，使体系的初始粘度增大。可使用时间延长；粒度分布过窄。造成可使用时间太短，固化太快。不利于浇注。只有当氧化铝晶粒大小匹配、粒度分布均匀。才能使浇注体系的初始粘度、可使用时间达到要求，浇注件的机电性能达到最佳。

| Abstract: | This paper expounds the fact that crystalline grain size and distribution of alumina filler affect the viscosity of epoxy pouring system.According to determinating initial viscosity and pot life of four kinds of sample,It can be seen that if grain size is much too small,the initial viscosity of the system will be very high and pot life will be very long.On the other hand,if crystal line size distribution is very narrow,pot life will be too short to pour easily.Only when grain size is suitable and distribution of size is even,it can make the initial viscosity of pouring system and pot life reach its request,electrom echanical properties of materials can get to better. |
