During transportation and storage, coal produces a lot of dust, which pollutes the environment threatens occupational health workers. Although many dust suppressants have been developed for prevention at work, implementation current does not meet requirements due to various factors such as hydrophobic nature harsh external environment. In this study, hydroxyethyl cellulose, acrylamide, stearyl methyl acrylate were used micelle polymerization prepare an environmental protection suppressant...
The flammability limits are essential parameters that reflect the risk of a gas explosion and affected by temperature, pressure, inert gas. Many industrial processes run at high temperatures pressures. Incidents involving combustible explosions frequent; however, issues with safety pressures never addressed. There have been no substantial advances in theoretical prediction for long time dearth perfect theories systematic data collection. factors, such as thermal decomposition slow oxidation,...
Recent research on liquid spray additives for coal dust suppression has been focused enhancing the wetting ability while neglecting mitigation of re-entrainment issue. The present study employs free radical polymerization approach to conduct graft co-polymerization involving sodium alginate, acrylamide, and caprolactam. Meanwhile, dodecyldimethyl betaine, as a surfactant, is introduced process prepare suppressant with cementing effects. FTIR XRD techniques are utilized microscopic...
The sprayed concrete in mine roadways suffers from a prolonged exposure to the harsh environment underground mine, leading its detachment which may compromise supporting strength. Besides, dust-cementing effect of conventional is poor, providing very limited contribution suppress dust-laden airflow. As such, present experiment uses sodium carboxymethyl cellulose as base produce novel thin spray material through graft copolymerization based on acrylic acid and polyaluminum chloride. This new...
ABSTRACT In the process of coal transportation and storage, a large amount dust is inevitably generated, which seriously threatens health miners causes waste resources. How to prevent control generated during storage key issue mine occupational safety research. this study, sodium alginate reacted with 2‐acrylamide‐2‐methylpropanesulfonic acid, resulting intermediate graft copolymerized acrylic acid prepare an environment friendly suppressant product suitable for storage. The microscopic...
