水玻璃自硬砂复合溃散剂的研究

The Study on the Compound Disperser of Cold-Setting Sodium Silicate Sand

研究了硬化剂炉渣粉、溃散剂滑石粉单独及复合使用对水玻璃砂初始强度、残留强度、可使用时间及抗吸湿性的影响。结果表明 :该复合溃散剂能大幅度降低水玻璃砂的残留强度 ,溃散性优良 ,成本低廉 ,具有一定的推广价值。

The influece of adding the deoxidizing slag as a curing agent for making steel and french chalk as a disintegration agent respectively or together on the original and residual strength ,bench life and moisture resistance of the sodium silicate sand was studied.The results show that the compound disperser can remarkably reduce the residual strength and has good collapsibility and low cost.Therefore,it has the value for itself to be popularized.
