Research on optimal formula of dustfall agent to remove blasting smoke
Abstract：The experiment adopted a number of base materials and surface-active agents to reduce the dust in smoke.Besides,corresponding additives were adopted to reduce poisonous and harmful gases during the blasting.Experiments focused on wettability and surface tension,using contrast experiment to determine optimal base material and surface-active agent,and also studied the influence of additives on their performance.The experimental results show that sodium chloride is the optimal base material,sodium dodecyl benzene sulfonate is the optimal surface-active agent,and copper sulphate and ammonium chloride as additives have almost no influence on performance of surface-active agent and base material.Therefore,adding this dustfall agent to the water bag during the blasting can effectively reduce the smoke concentration.
