摘要
本文制备了醋酸钙美(CMA) 冰雪融化剂并在实验室小试了其融冰能力,并与氯化钠和氰化钙进行了比较。结果表明,CMA组成和环境温度对CMA融冰效果有很大影响。CMA适宜在环境温度-11℃以上使用,CMA中钙镁比为7:3时,融冰能力可以达到氯化钠和氯化钙的75％～80％,是一种优良的冰雪融化剂。
Calcium Magnesium Acetate(CMA) was kprepared as snow and ice melting agent and tested for ice-melting in small scale, and compared with sodium chloride and calcium chloride. The results show that the ingredient of CMA and environment temperature determine the ice-melting resulto CMA should be used at above -11℃. When Mg/Ca molar ratio in CMA is 7/3, the capability of CMA for ice-melting is up to 75%-80% of sodium chloride or calcium chloride. CMA is effective for ice-melting.
