Calcium acetate eco-friendly deicer was prepared using waste oyster shell as a raw reactant material and its physicochemical properties were investigated. The waste oyster shells were converted to a calcium acetate deicer by reaction with acetic acid at ambient temperature. The physicochemical properties of the prepared calcium acetate deicer were analysed using various analytical method. The ice melting and metal corrosion characteristics of the calcium acetate deicer synthesized from the waste oyster shell were evaluated by comparison with those of the calcium chloride and sodium chloride deicers. The chloride deicers severely corroded the metal, but the calcium acetate deicer prepared from the waste oyster shell did not cause metal corrosion. The ice melting performance of calcium acetate prepared from the waste oyster shell was lower than that of calcium chlorides, however, the addition of sodium hydroxide could significantly improve the ice melting capacity.
以废弃牡蛎壳为原料制备环保型醋酸钙融雪剂，并对其理化性质进行了研究。在常温下，用醋酸将废弃牡蛎壳转化为醋酸钙融雪剂。采用多种分析方法对制备的醋酸钙融雪剂的理化性质进行了分析。通过与氯化钙和氯化钠融雪剂的比较，评价了由废弃牡蛎壳合成的醋酸钙融雪剂的融冰和金属腐蚀特性。氯化物融雪剂严重腐蚀金属，而由废弃牡蛎壳制备的醋酸钙融雪剂则不会引起金属腐蚀。由废弃牡蛎壳制备的醋酸钙的融冰性能低于氯化钙，但加入氢氧化钠可显著提高其融冰能力。
