Abstract

UN METODO Y UN APARATO PARA EMPLEAR UN SURFACTANTE QUE ESTA PREVISTO CON EL FIN DE AYUDAR A LA LIBERACION DE CADA UNO DE LOS COMPONENTES DE MOLDE DE UN MOLDE CON MULTIPLES PARTES EMPLEADO EN EL MOLDEADO DE ARTICULOS POLIMERICOS, POR EJEMPLO, LENTES DE CONTACTO HIDROFILICAS, EN LA REALIZACION DEL PROCEDIMIENTO DE MOLDEADO DE ARTICULOS POLIMERICOS. EL SURFACTANTE SE APLICA EN FORMA DE PELICULA O REVESTIMIENTO SOBRE PARTES DE SUPERFICIE DE UNO DE LOS COMPONENTES DEL MOLDE CON EL FIN DE FACILITAR LA LIBERACION ENTRE LOS COMPONENTES DE MOLDE DURANTE EL DESMOLDEADO, Y LA RETIRADA DEL MATERIAL DE MOLDEADO POLIMERICO SOBRANTE DEPOSITADO ADHESIVAMENTE SOBRE SUS SUPERFICIES.
