水玻璃磁化改性对水玻璃砂性能的影响研究结果表明，磁化改性水玻璃砂可延长可使用时间２５％左右。由于提高了水玻璃粘结强度，使水玻璃加入量降到２．５％左右，并改善了水玻璃砂溃散性。指出磁化改性效果会在２４小时后消失。发现水玻璃输导管材料对磁化改性效果有影响。
The effect of water glass magnetization modification on the performance of sodium silicate sand The results show that the magnetizable water glass sand can be extended for about 25% of the usable time. As the water glass to improve the bonding strength, the amount of water glass dropped to 2.5%, and to improve the water glass sand collapsible. Pointed out that the effect of magnetization will disappear after 24 hours. It was found that the material of the water glass tube has an influence on the magnetization modification effect.
