Abstract

PROCEDIMIENTO DE FABRICACION DE UNA VEJIGA DE MATERIAL ELASTOMERO UTILIZADA EN UN APARATO MEDICO DE TRANSFUSION. SE MEZCLAN DE MANERA HOMOGENEA UN POLIISOPRENO SINTETICO QUE CONTIENE UN 90 A 98% DE ENLACES CIS-1,4, 3 A 10 PARTES POR 100 PARTES DE POLIISOPRENO SINTETICO DE DIOXIDO DE SILICIO O DE NEGRO DE HUMO EN PARTICULAS Y 1 A 2 PARTES POR 100 PARTES DE POLIISOPRENO SINTETICO DE UN AGENTE DE VULCANIZACION. SE SOMETE LA MEZCLA A CONDICIONES DE VULCANIZACION, A LA VEZ QUE SE LE DA FORMA DE UN CUERPO TUBULAR. SE EXTRAEN MEDIANTE UN SOLVENTE LOS PRODUCTOS DE DEGRADACION DEL AGENTE DE VULCANIZACION. SE PONE EN CONTACTO DICHO CUERPO CON 0,2 A 2 PARTES POR 100 PARTES DE POLIISOPRENO SINTETICO DE UNA SOLUCION LIQUIDA DE UN ANTIOXIDANTE NO TOXICO SUSTANCIALMENTE NO LIXIVIABLE, EL CUAL SE INTRODUCE EN EL CUERPO POR DIFUSION. SE RETIRA EL CUERPO DE LA SOLUCION Y SE ELIMINA EL SOLVENTE MEDIANTE SECADO.
