The Influences of the Structure of Nozzle on Coating Effect in Particle Coating by Fluid-Rapid Expansion of Supercritical Solutions

Abstract:

Red phosphorus microencapsulation flame retardant was prepared by Supercritical Fluid-Rapid Expansion of Supercritical Solutions (SCF-RESS),using a self-made special nozzle. The influences of the reversed gyrator, and the rotation angle of the front revolvable tie-in on coating effect were discussed. The results showed that the coating effect which the reversed gyrator was installed on the nozzle was better than it which the reversed gyrator was not installed on the nozzle.The coating effect is the best when the rotation angle of the front revolvable tie-in is 10°,and the coating effect is worse when the rotation angle of the front revolvable tie-in is exceed 10°.
