摘要
研究了几种提高蛭石膨胀度的制备方法 :离子浸渍处理、喷油处理后煅烧和瞬时减压法煅烧。实验结果表明 ,对蛭石进行离子浸渍、喷油处理改性 。
Several methods for increasing the volume yield of vermiculite were research. The methods comprise of impregnating vermiculite ore by magnesium or aluminum ion solution,oil treatment of vermiculite and calcining of vermiculite under the condition of high pressure,then instantaneous decompression. Experimental results indicated that after modification of vermiculite by ion impregnating or oil treatment,the volume yield of expanded vermiculite can be obviously increased.
