METHOD AND APPARATUS FOR SUBSTANCE CAPSULATION

摘要

FIELD: extrusion moulding. SUBSTANCE: method provides for production of substance flow, that is subjected to capsulation inside capillary tube, extrusion of the substance from the tube, axial coextrusion of polymeric solution on periphery of the tube to capsulate substance. Before extrusion of capsulated substance its flow is segmented by carrying liquid. Then temperature of capsule formation is decreased and final change of solvent from polymeric solution for setting stuff is exercised. There is description of apparatus to realize the method. EFFECT: increased efficiency.
