铁路煤炭运输用抑尘剂的研究与应用

Nowadays,the coal transportation of the railway generally used the flatcar in China.Because the jolting which the roadbed,the rail switch and the rail facility created,in addition the wind action and so on each kind of reason enabled in the vehicles the coal surface layer coal to scatter the ground,which not only led to the loss of coal and coal dust pollution,but also to the rail transport have serious safety incidents and hidden dangers.There were many wanys to prevent the coal scatters,for example:The machinery capping,the canvas cover,sprays the dust suppression and so on.Chemistry dust suppression is one of the most effective way to dust prevention and it was developing since had appeared.My thesis was to apply chemistry dust suppression technology in the coal dust control domain. The prime task of my thesis was to develop one kind of appropriate dust suppression,which could reduce the coal loss in the transportation through the way that sprayed the dust suppression to cover the coal surface.We decided to synthesize lignosulfonate grafted acrylic dust inhibitor,the acrylic acid modified lignosulfonate from dust suppression preparation craft,the dosage,the exploitation condition was determined according to several field experiments.The dust suppression not only had the economic efficiency also had the environment benefit.
