Therefore, stopping the hardening process of particles from growing is the key of increasing CO2 sodium silicate sand bond strength. 所以,提高CO2水玻璃砂粘结强度的关键在于抑制硬化过程中胶粒的过于长大。
Study and Application of GS-ⅱ Strengthen-collapsing Agent for Sodium Silicate Bond GS-Ⅱ型水玻璃增强溃散剂的应用研究
The bending strength with 2% borax as bond was higher than that of samples with 1% sodium silicate as bond. 经与硅酸钠粘结剂比较,加入2%硼砂试样的抗弯强度高于1%硅酸钠试样的抗弯强度。
The viscosity of sodium silicate may be reduced, thus the bond strength may be increased by magnetization. The magnetization result differs in different magnetic fields. 水玻璃经磁场处理可以降低粘度,提高水玻璃砂的粘结强度,不同磁场强度下的磁化效果不同。
