Type of GF is used for separating varous emulsion,especially for liquid-liquid separation with slight gravity difference and liguid-liguid-solid separation with a little foreigh matter,such as transformer oil,turbine oil,lubricant,fuel oil,dye,fat,saponification and various micropowder and for purifying span-80 liquid separating various oral liquid and medical liquid and "920"and plasma and biologic medicine,extracting palsma from animals'blood,refining phosphatide of bean,etc.and treating sewage and separating oil and water.Type of GQ is used for separation of various suspension which is difficult to be separated especially for separation of solid-liquid suspension which has low concentration,high viscosity,small granularity and very small difference of solid-liquid gravity,such as clarification of various oral liquid,desludgement of coal tar and graphite,extraction of protein,seaweed and jelly,refinement molasses,separation of blood and settlement of vaccine hypha and various dextroses and purifying paint,dye,various,resin and rubber solution molasses and refinement of regetable oil.
