The Experimental Research Of Coal Ash Fused Fiber Composite Paper

Because of the environmental pollution and water waste and take a lot of farmland caused by fly ash emissions, and the utilization of fly ash only 70% ,we should find a new way of utilizing its urgently; China's paper industry is also facing higher raw material prices, pollution and other issues, so this study was to partially replace plant fiber as fiber resource after changing fiber property, enhancing fiber flexibility and strength.1) The experimental research of dispersion of coal ash fused fiber in water:0.5% HC1 with fiber, the fiber can significantly reduce the velocity; Also available on various concentration slurry adding 0.1% to 1% cationic surfactant, the same can be effectively dispersed the medium fly ash superfine fiber.2) Methods for property change of coal ash fused fiberlf the fiber's surface is no longer smooth, the sheet strength will enhance because the bonding between the fibers enhancd, so we should change the fiber's structure. After Ca(OH)₂, CO₂ treatment, optimized treatment method was determined by comparing the property of composite paper made with coal ash fused fiber before and after treatment experiment, their white and tensile strength increased significantly.HF acid, sodium hydroxide solution on the surface of fly ash have different corrosion, but also a very good fiber modification methods.3) The experimental research of Softening the coal ash fused fiber:to improve the crisp hard features of the coal ash fused fiber, serous add cationic surfactant or fiber acidification and heating, can improve the strength of the sheet in different degree.4) The experimental research of the methods to enhance strength of composite paper made with coal ash fused fiber: the strength of composite paper made with coal ash fused fiberis low, there are many ways to enhanceit and they are very good, through internal method or external method, all can be enhanced sheet strength.Coal ash fused fiber composite paper has very good thermal, humidity, and radiation resistance as well as very good property of mold and corrosion prevention. It can be used in manufacturing corrugated paper, packing paper and high and medium quality writing paper. Pure coal ash can also be used in producing filter paper.The use of coal ash and coal ash fused fiber in paper-manufacturing creates new resource from the waste and helps us keep a better environment.
