摘要
为了有效抑制汽车运输路面的扬尘，选择低浓度渣油－水乳化液作为抑尘剂，通过在实验室大量的试验，掌握了一组渣油乳化的最佳配方及其制备工艺，即渣油３％－６％，乳化剂约０．５％，水９３．５％－９６．５％，制备温度＞７０℃．经过室内和现场大规模试验表明，当路面喷洒量达到２．２ｋｇ／ｍ２时，其有效抑生时间达到１０ｄ以上，并且在一定程度起到养路的作用，长期使用可取得显著的综合经济效益．
In order to control the dust raising on the dirt roads efficiently,the tar emulsified liquid with low concentration was taken as the dust suppressant. Based on a great nUmber of experiments in laboratory,the optimum compositions of surfactants and the prepared condition for emulsifying tar were achieved, tar is 3%-6%,surfactants is 0.5% and water is 93. 5%-96.5 Wt.%.The prepared temperature is greater than 70℃.Depended on a lot of tests both in laboratory and field, the results showed that the liquid is very efficient for binding dust and maintaining the dirt roads. The active time can reach more than 10 days,when the liquid is sprinkled on the road in 2.2 kg/m2.A rational profit can also be achieved after it is used for years.
