城市道路抑尘剂的作用与应用简析

Brief Analysis on Action and Application of Urban Road Dust Depressor

摘要:

从城市道路颗粒物、扬尘来源、抑尘剂的角度，介绍颗粒物现状、扬尘来源、产品性能现状、感官、理化指标检测（PH值为7.12、亚硝酸盐氮0.000 059%、硝酸盐氮0.003 09%、氯化物0.094%）。PM2.5、PM10平均抑尘效率分别为95.8%和96.7%。从而，为城市道路抑尘技术的发展、推广、应用，积累经验，提供参考。

Abstract:

From the points of urban road particulate matter, flying dust source and dust depressor, the current situation of particulate matter, the flying source, the current situation of product performance, the sense organ and the detection of physicochemical indexes (PH value 7.12, nitrite nitrogen 0.000 059%, nitrate nitrogen 0.003 09% and chloride 0.094%) are introduced. The average dust depressing efficiencies of PM2.5 and PM10 are 95.8% and 96.7% respectively. Thereby, the experience is accumulated and the reference is provided for the development, promotion and application of urban road dust depressing technology.
