Abstract

L'invention a pour objet un appareil pour la vulcanisation en continu d'un matériau élastomère qui comprend une chambre de vulcanisation pourvue d'une entrée et d'une sortie pour ledit matériau élastomère, agencée pour contenir un sel liquide de vulcanisation stable, des moyens étant prévus pour faire circuler le liquide dans la chambre à la température et à la pression de vulcanisation requises, une chambre de refroidissement étant reliée à la sortie de la chambre de vulcanisation et étant équipée de moyens pour faire circuler sous pression un agent de refroidissement gazeux tel qu'il n'interfère pas avec l'action de réticulation et qu'il ne réagisse pas avec le matériau d'isolation, lesdits moyens comprenant une unité de refroidissement à gaz et une pompe de circulation des gaz.The invention relates to an apparatus for the continuous vulcanization of an elastomeric material which comprises a vulcanization chamber provided with an inlet and an outlet for said elastomeric material, arranged to contain a stable liquid vulcanization salt, means being provided for circulating the liquid in the chamber at the required vulcanization temperature and pressure, a cooling chamber being connected to the outlet of the vulcanization chamber and being equipped with means for circulating a cooling agent under pressure gaseous such that it does not interfere with the crosslinking action and that it does not react with the insulation material, said means comprising a gas cooling unit and a gas circulation pump.
