摘要
适当的挤压作用,有利于凹凸棒石的水化和粘结性能、胶体性能的发挥,这是凹凸棒石粘土加工必须的一道或多道工艺过程。但是过多的挤压作用,对其显微结构会产生一定的纤维断裂及Si-O-Si键断裂破坏,从而降低了凹凸棒石的粘结性能。
The proper squeeze which is a or repeated essential technological process before processing the attapulgite clay can make it dissolved and make it more viscid and colloidal. But the excessive squeeze can break the micro-structure and the Si-O-Si band, thus,the viscidity is weakened.
