sodium silicate-bonded sand

The Technology of Sodium Silicate Sand Hardened by Ester and the Reclamation of the Used Sand

酯硬化水玻璃砂工艺及其旧砂再生

As the bending strength of sodium silicate sand cured by ester method is much higher than that cured by CO_2 method the analysis shows that the key point is the refinement of grains of silicate gel.

分析了酯法比CO2法水玻璃砂强度高的原因，指出充分发挥水玻璃粘结效率的关键在于细化水玻璃凝胶胶位。
