摘　　要：扬尘会造成城市灰霾天气,对空气质量产生重大影响。将以农作物废料为原料制备的新型环保抑尘剂LM应用于金沙水电站施工过程扬尘控制。实验结果表明:抑尘剂LM质量浓度在1%~1.5%时,对金沙水电站施工现场红、黄、灰三大类主要扬尘均能起到有效抑尘作用,保湿时间可达10 h以上,且能较快渗透,尤以在红尘中的渗透速率最快。SEM结果显示,喷洒抑尘剂尘样表面能形成均匀光滑固结层。Dust will cause ash haze weather in city and have a significant impact on air quality.A new environmentally-friendly dust suppressant LM prepared from crop waste was applied to Jinsha hydropower station.The experimental results showed that when the quality concentration of the new type of environmentally-friendly dust suppressant LM was 1%to 1.5%,it can effectively suppress dust in the three major categories of red,yellow and gray dust on the construction site of the Jinsha hydropower station.The moisturizing time can reach more than 10 h,and it can penetrate quickly,especially in the red dust the penetration rate was the fastest.The SEM results showed that a smooth and uniform consolidation layer could be formed on the dust-like surface.
