摘要
提出了喷射载冷剂HCFC123动态制冰的基本原理和制取冰浆的方法,分析了乙二醇、Tween-80、十二烷基硫酸钠及十二烷基硫酸钠+丙三醇复配溶液等4种添加剂在制取冰浆过程中的特点,以冰浆的流动性、含冰率(IPF)、HCHFC123能否从冰浆和含添加剂的溶液中析出作为判断依据,找到了十二烷基硫酸钠和丙三醇复配溶液是制取冰浆的最佳添加剂。
The principle of dynamic making ice by spraying secondary refrigerant HCFC123 and the method of making ice slurry were presented. The characters of four additives--ethylene glycol, Tween-80, sodium dodecyl sulfate, mixed liquor of sodium dodecyl sulfate ＆ glycerin were analyzed in the course of making ice slurry. The results show that the mixed liquor of sodium dodecyl sulfate ＆ glycerin is the best additive for making ice slurry based on the liquidity of ice slurry, ice percent factor （IPF） , and whether HCFC123 can be separated out from ice slurry and the solution containing additives or not.
