Abstract

Un procedimiento para vulcanizar caucho en hojas, que comprende formar un rollo de capas alternadas de caucho en hojas sin vulcanizar que contiene agentes vulcanidazores y una hoja de material dieléctrico diferente de dicho caucho, estando dicho material dieléctrico en hoja incorporado en dicho rollo bajo una tensión de por lo menos, 0,18 kgrs/cm lineal de su anchura. calentar dieléctricamente el caucho no vulcanizado en dicho rollo a la temperatura de vulcanización disponiendo dicho rollo en un campo eléctrico de alta frecuencia, mantener en torno de dicho rollo una atmósfera a una presión de por lo menos 0,3 Kgrs/cm2 y elevar dicha atmósfera en temperatura simultáneamente con dicho caucho por medios calentadores independientes de dicho campo; terminar dicho calentamiento dielectrico cuando la temperatura de dicho caucho ha sido elevada aproximadamente a temperatura de vulcanización y utilizar luego solamente dichos medios calentadores independientes para mantener dicho cauchoen dicho rollo a dicha temperatura de vulcanización durante un periodo de tiempo rquerido para conseguir la vulcanización.
