摘要
通过正交试验研制出了新型液体硬化剂,用此配制的水玻璃自硬砂,具有较高的24h 强度和较低的残留强度。此种硬化剂价格低、无毒无味。
A new kind of liquid hardener is studied out through orthogonal test.Sodium silicate hardened by this hardener has higher 24h strength and lower remained strength.Other ad- vantages of the liquid hardener are that it is cheaper,nonpoisonous and smelless.
