PREPARATION OF ROAD DUST SUPPRESSANT WITH AGRICULTURAL WASTE STRAW

Beijing Key Laboratory of Regional Air Composite Pollution Prevention and Control, Beijing University of Technology, Beijing 100124,China

摘要

摘要: 以玉米秸秆为主要原料,采用纤维素酶对其进行酶解,通过添加环境友好型助剂,制备出一种可用于道路扬尘控制的环保型道路抑尘剂。采用响应面法优化制备了该抑尘剂,并对所制备抑尘剂产品的吸湿保湿性能及表面张力等参数进行了测试表征;以抑尘剂吸水率为评价指标,确定木聚糖酶、酸性纤维素酶、纤维二糖酶和β-葡聚糖酶的最佳质量比为2∶2∶1∶1;以抑尘剂物化性能和实际性能确定出秸秆∶丙三醇∶氯化镁∶α-烯基磺酸钠∶聚丙烯酰胺的最佳质量比为1∶4∶3∶0.05∶0.001(干重)。所开发抑尘剂具有良好的润湿性能及抗蒸发性能,在7.8 m/s风速下,2 h内抑尘率达到100%。

Abstract: An environment-friendly road dust suppressant was prepared by using corn straw as the main raw material, enzymatic hydrolysis of straw with cellulase and environmental-friendly additives. The moisture absorption, moisture retention and surface tension of the dust suppressor were tested and characterized. The response surface methodology was also used to optimize the formula of dust suppression agent and prepare the samples of dust suppression agent. The optimal mass ratio of xylanase, acid cellulase, cellulobiase and β-glucanase was 2∶2∶1∶1, in which the water absorption rate of dust suppression agent was used as the evaluation index. The optimal mass ratio of straw∶glycerol∶magnesium chloride∶α-enyl sulfonate∶polyacrylamide was 1∶4∶3∶0.05∶0.001 based on the physical and chemical properties and practical performance of dust depressant. The developed dust suppressant had good wettability and anti-evaporation performance while the dust suppression rate could reach 100% within 2 hours at the wind speed of 7.8 m/s.
