水玻璃砂 Ｃ Ｏ２ 吹气硬化工艺， 采用脉冲送气代替连续送气有助于 Ｃ Ｏ２ 气体的弥散， 提高了 Ｃ Ｏ２ 气体的有效使用率， 防止减压阀因 Ｃ Ｏ２ 气化时吸热而冻结阀嘴， 节约 Ｃ Ｏ２ 气体。
Water glass sand C O2 inflatable sclerosis process, the use of pulsed gas instead of continuous aspirated C O 2 gas to help disperse the gas to improve the effective use of C O 2 gas to prevent the pressure relief valve due to C O2 vaporization and freeze valve Mouth, save C O2 gas.
