中文摘要:

      目前融雪剂主要有两大类,第一类是氯盐系,通常指氯化钠、氯化钙、氯化镁、氯化钾等,其融雪效果好,原料易得,价格便宜。第二类是非氯盐有机物系,通常指醋酸钙、醋酸镁、醋酸钾和特殊有机物等为主要成分的融雪剂,这类融雪剂冰点高、融雪效果较差、价格昂贵不易推广,只局限于机场、跑道、大桥等特殊地段使用。随着各地区对环境保护力度的加大,出现混合型融雪剂_[1-3],其在上述两类融雪原料中添加缓蚀剂以减小对道路、设施、植被、土壤的侵蚀。本文利用盐湖提钾后的尾矿氯化镁(MgCl₂.6H₂O)在110℃—127℃干燥后作为融雪原料,研究不同低温段的融冰效果,与传统融雪剂氯化钠的融冰能力进行对比,得到了理想结果,为尾矿氯化镁开辟了新的利用方向。

英文摘要:

      Currently there are two major categories of deicing salt, The first category is usually refers to sodium chloride、 calcium chloride、 magnesium chloride、 potassium chloride, etc. Its snow effect is good, cheap and readily available raw materials. The second category is often referred to the Department of organic chloride, calcium acetate, magnesium acetate, potassium acetate, and special organic matter as the main ingredient of deicing salt, deicing salt such high freezing point, the effect of poor snow expensive not easy to promote, confined special section of the airport runway bridge like. With the various regions of increasing the degree of environmental protection, appears mixed deicing salt,Add inhibitor in the above types of raw materials to reduce the melting snow on roads, facilities, vegetation, soil erosion. In this paper, the use of tailings Salt Lake potassium chloride(MgCl2.6H2O) after,After drying at 110 ℃ -127 ℃ snowmelt as raw material,,Study the effect of different low temperature melting ice segment, compared to the traditional ice-melting capacity of sodium chloride deicing comparative study to obtain the desired results for the tailings using magnesium chloride to open up new directions.
