Development of Antifreezing High‐Efficiency Dust Suppressant for Railway Coal Transportation
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In the process of railway coal transportation, a large amount of coal dust is dispersed, causing serious economic loss and environmental pollution. In order to improve the low‐temperature dust suppression performance, the present study has developed an antifreeze‐type, high‐efficiency railway coal transportation dust suppressant (hereinafter ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Coal is a natural macromolecular substance composed of complex organic molecules and a small amount of minerals. Its chemical composition and microstructure are highly complex and variable, and no unified definition exists. This inherent structural complexity underscores the theoretical significance of constructing accurate macromolecular ...
