Description

(54) СПОСОБ ПРКССОВАКИЯ КОМПОЗИЦИЙ, СОДЕРЖАЩИХ РЕЗИНОВУЮ КРОШКУ(54) METHOD OF PRESSING COMPOSITIONS CONTAINING RUBBER CRUM

2СОО кгс/см, при времени формовани  и вулканизации от 3 до 15 мин возможна также деструкци  поверхностного сло  час1иц, что обеспечивает лучшие услови  дл  взаимной диффузии сегментов каучука совулканизуемых фаз.2COO kgf / cm, at the time of molding and vulcanization from 3 to 15 minutes, destruction of the surface layer of particles is also possible, which provides better conditions for mutual diffusion of the rubber segments of the vulcanized phases.

Предлагаемый способ переработки формуемо резиновой композиции в изделие опробован на термопластавтомате ТП-63Х.The proposed method for processing a formable rubber composition into a product was tested on an injection molding machine TP-63X.
