Researches of structural-mechanical properties of coal tailings as disperse systems

Ver/

Justification of physic mechanical parameters of preforming composite fuel requires research of structural and mechanical properties of coal tailings as disperse systems. Researches were conducted by means of methods of measurement of structural and mechanical properties of disperse systems. Coal tailings (fraction of 0-1 mm) as the disperse breeds including a disperse phase and the disperse environment, represent the system based on physical and chemical interaction of its components. Existence of structure gives to system peculiar mechanical properties. These properties – elasticity, durability, plasticity, viscosity – depend on the chemical nature of the substances forming this system; decide by molecular forces of adhesion between structure elements, their interaction on the dispersive environment and extent of development of structure in all volume of system. Therefore the improvement of structural and mechanical properties necessary for process of their preforming demands research. (266.6Kb)
