HC plastic mesh information: Coal dust is the chronic safety of the major disaster, not only prone to explode under prolonged exposure can lead to pneumoconiosis. Has become the number one occupational pneumoconiosis. To reduce the dust hazard, protect the safety production, Shandong University of Technology, Professor Tan Yun-Zhen, Yang Jing, who associate professor in the depth of the research team composed of physical and chemical characteristics of coal dust and the wetting mechanism of the foundation, after repeated experiments, successfully developed a new types of coal dust Flame Retardant . According to reports, the original use of coal mine dust suppression equipment to such a coal dust flame retardants added to the water spray dust, not only can effectively capture the dust, coal dust suppression secondary flying, you can also burn and to prevent coal dust explosion Mine operating environment to improve and enhance resilience mine, coal mine production safety is of great practical significance.





Dust Control Technology has been the research focus of coal mining at home and abroad. Domestic and foreign research workers in the comprehensive work done a lot of dust and dust, also made many achievements, but the previous Comprehensive dust prevention measures often treat only the symptoms, not the root cause, mainly depend on the means of water, coal dust on the respiratory low capture rate, and dust while not prevent coal dust explosion, causing coal dust explosion occur.

Shandong University of Technology over the years successfully developed the new coal-dust flame, not only effectively reduce the coal dust, coal dust and change the traditional physical proof of chemical explosions, coal dust control technology is a major breakthrough.





Reporter learned this from a number of flame retardants in the optimization of the flame retardant polymer dust and dust toxic, non-irritating taste, on human skin and no corrosion of equipment, use of less efficient High, low cost per ton of coal is only 5-7 yuan, without adding new equipment, as long as the dust in the mine water can be added to the fire retardant spray, easy to operate. Experimental results show that adding the flame retardant in the coal dust, the dust explosion flame length shortened, even without a flame, explosive coal dust significantly reduced.





In the Shandong Province Science and Technology Department of the expert appraisal meeting, the Chinese Academy of Engineering, Yuan Shi Hongbo, director of the identification of potential for the Committee considers that the project put forward a quantitative characterization of particle size distribution of dust structure of the target surface to determine the existence of fat coal dust hydrocarbons, aromatic hydrocarbons and oxygenated functional groups the three groups to study the dust composition, physical and chemical structure and wettability of the relationship between coal dust, from the microscopic exploration of the respirable dust wetting mechanism is difficult to determine the impact of coal dust wettability of the main factors that optimized the coal dust flame retardants, developed a flame retardant polymer dust and dust, successfully coal dust dust, dust proof and the combination of project objectives international advanced level.





It is understood that coal dust and dust flame retardant polymer research and application of technology development projects in Shandong Province, the project has a broad application of the results and prospects of the market, economic and social benefit.
