3. Performance and use:Coal-water slurry dispersant is a new coal fuel instead of oil fuel, this product is an important composition of coal-water slurry. After adding M additive, the slurry will have lower viscosity, higher density, better dispersibility, fluidity and stability. This additive can improve the slurry and also increase the coal slurry’s combustion efficiency. It helps on environmental protection and energy conservation. It is applicable to most kinds of coal. Usually 0.3-1% by weight( of the dry coal’ weight) is needed to be added, then slurry of 62-68% will be formed. The viscosity is 900-1200Pa.S. it can be stable for 60days.
