摘要
氯盐融雪剂因其融冰除雪性能优异、价格低廉、易于获取而得到广泛应用.为探究氯盐融雪剂的温度适用性不同、标准不统一、撒布方式粗略等问题,该文通过改进的SHRP融冰试验,分析了温度、固液态及撒布方式对NaCl、CaCl2、MgCl2 3种常用氯盐融雪剂除冰性能的影响.试验结果表明:氯盐融雪剂的除冰性能对温度具有显著的敏感性;MgCl2、CaCl2两种融雪剂在融化过程中存在"放热"效应;同种氯盐融雪剂在固态下的融冰效率高于液态下的;同种氯盐融雪剂在不同撒布方式下融冰效率不同,其中,在线性撒布下除冰能力最强.根据试验结果,建议使用固态线性撒布的方式,并根据环境温度选择适宜的融雪剂.
Abstract
Chlorine salt snow-melting agent has been widely used because of its excellent ice-melting and snow-removing performance,low price,and easy access.In order to explore the problems of different temperature applicability,non-uniform standard,and rough spreading methods of chlorine salt snow-melting agents,this paper analyzed the influence of temperature,solid and liquid state,and spreading methods on the ice-melting performance of three commonly used chlorine salt snow-melting agents,namely NaCl,CaCl2,and MgCl2,through an improved SHRP ice-melting test.The test results show that the ice-melting performance of the chlorine salt snow-melting agent has strong temperature sensitivity.MgCl2 and CaCl2 snow-melting agents have an exothermic effect during the melting process.The ice-melting efficiency of the same chlorine salt snow-melting agent in the solid state is higher than that in the liquid state.The ice-melting efficiency of the same kind of chlorine salt snow-melting agent is different under different spreading methods,and the linear spreading shows the strongest ice-melting performance.Based on the test results,it is suggested to use the solid-state linear spreading method and select the appropriate snow-melting agent according to the ambient temperature.
