CMA类环保型融雪剂的应用研究进展

Research Progress on Application of CMA Environmentally Friendly Deicer

醋酸钙镁盐(CMA)可替代氯盐,用于机场、高速公路等道路除雪,根除氯害,是一种环保型融雪剂。介绍了国内外融雪剂的品质指标和应用研究进展,重点是利用生物质热解废液替代冰醋酸制备CMA类融雪剂的工艺方法,经济可行。与传统氯盐融雪剂相比,CMA环保型融雪剂腐蚀性低、毒性低、融雪效率高、冰共熔点低、可生物降解等。

Calcium magnesium acetate（CMA） is a kind of environmentally friendly deicer without elemental chlorine,which can be used for snow melting in airports,highways and other public roads.Introduces the research progress and quality specifications of deicers at home and abroad,highlighting a cost-effective process of using biomass pyrolytic wastewater instead of glacial acetic acid to produce CMA deicer.Compared to traditional chloride salts,CMA has advantages of low corrosivity,low toxicity,high snow melting efficiency,low melting ice point,biodegradable and so on.
