BS-Ⅰ型乳液抑尘剂防治矿山运输路面扬尘

Spray of Emulsion Suppressant for Controlling Dust in the Roadway of the Shangrdong Aluminium Mine.

由2.0—5.0％乳化油、0.05％乳化剂和水制备而成的BS-Ⅰ型乳液抑尘剂,在山东铝厂矿山公司使用表明,一次喷洒0.8—2.0kg/m^2,能使砂土或砂石运输路面粉尘从9.6—33.3mg/m^3(平均19.5mg/m^3)。在10—15昼夜内降至10mg/m^3以下(平均4.3—5.8mg/m^3)。使用该抑尘剂,大大减轻了路面扬尘污染,同时降低了车辆磨损和油耗。乳液抑尘剂良好的防尘效果主要是由其自身的物理化学性质决定的。

Spray with a dosage of 0.8-2.0 kg/m2 of the emulsified suppressant prepared from 2.0-5.0% pre-treated heavy oil, water and 0.05% emulphor could make the concentration of dust in the atmosphere above the roadway of the Shandong Aluminium Mine reduced from 9.6-33.3 mg/m3 to lower than 10 mg/m3 (average 4.3-5.8 mg/m3) within 15 day. Fu-ther exploration found that the excellent dust suppressing effect resulted from the physicochemical characters of the emulsion.
