摘要
本文通过对Epon812环氧树脂熟化(聚合)体系的应用和测试比较,报导了温度对Epon812环氧树脂熟化体系中的单体有影响,而对混合后的整个熟化体系几乎没有影响。极微量的水份对已混合的熟化体系的熟化交联有促进作用;已吸潮的单体置40～45℃烘箱3～5小时,其熟化性能可恢复到未吸潮状态。同时指出,通常应用于电镜包埋的Epon812熟化体系在45℃时即能达到完全熟化程度,这在免疫电镜应用过程中,对防止抗原生物活性的减少有一定的实用价值。
According to the use and comparative test of Epon 812 epoxy resin,this paper reports that humidity has an effect on the epoxy resin monomers hut mixed polymerized system of the epoxy resin.Extremely trace water can promote mixed polymerized system of the epoxy resin to polymerize;If moistened epoxy resin monomers are put in the baking oven at 40—45℃ for 3—5 hours.So,its characteristics of polymerzation can be recovered;And the paper also point out that the polymerization system of Epon 812 epoxy resin for electron microscopic sample may be polymerized completely at 45℃,which has some practical value for preventing reduction of bio-reaction of antigen in the field of immuno—electron microscopy.
