环氧化物固化废树脂过程中第三组分对固化体温度的影响

EFFECT OF THE THIRD COMPONENT ON SOLIDIFICATION HEAT OF SPENT RESIN IN SOLIDIFICATION PROCESS WITH EPOXIDE

一、前言离子交换树脂在核工业中被广泛地用于纯化、浓缩和分离过程。因受辐照影响和达到饱和等原因,树脂的物化性能变坏而成为放射性废物。由于其颗粒小,易分散,有引起污染和着火的危险,对它的处理成为人们十分关心的问题。将树脂转化成稳定的固化体被认为是一种理想的方法,现已开发多种固化工艺。

Effect of the third component on solidification heat of IER-epoxide system is described in this paper. In order to decrease solidification heat (or temperature) ,the Fontainnebleau sand is chosen as inert filling agent. According to measurement of solidified form properties (including hardness and inflation in water and solidification heat), optium constituent is determinated, that is: IER——50%;Epoxide ——40% ;Sand——10%. It can meet the temperature requirment in solidification process.
