水玻璃砂高效溃散剂的实验研究

Study of an Efficient Silicate Sand Collaps Agent

研究了一种水玻璃砂高效溃散剂Ａ，当水玻璃加入量为５％～８％时，在保证生产所需的常温性能的条件下，使ＣＯ２－水玻璃石英砂的溃散性得到极大的改善。

An efficient sodium silicate sand collaps agent was studied. When sediurn silicate concent was 5 %- 8 %,the collaps agent significantly improved the sodium silicate - sand collapsibility,and the properties at atrnospheric temperature also met the need of casting production.
