METHOD OF CONTINUOUS PRODUCTION OF CYLINDER OR HOLLOW BODIES OF OTHER CONVEX SECTION

摘要

FIELD: production of polymeric articles, for instance glass plastic ones, obtained by application of winding of glass fibre filler impregnated with binder. SUBSTANCE: the method consists in application of winding of glass fibre filled preliminarily impregnated with binder on a rotating mandrel, curing at a high temperature with the aid of a high-frequency electromagnetic field and subsequent cooling to the ambient temperature. The high-frequency electromagnetic field at a frequency of <EMI ID=0.114 HE=6 WI=21 TI=CHI> Hz is induced by a working inductor, whose length is selected with due account made for the rate of runoff of cured glass plastic from the mandrel and the optimum time of treatment in the working inductor. Curing is conducted at a temperature of 155 to 165 C. EFFECT: facilitated procedure.
