Abstract

"PROCESSO PARA FABRICAçãO DE UM MEIO DE FILTRO E MEIO DE FILTRO PRODUZIDO DE ACORDO COM ESTE PROCESSO". A invenção se refere a um meio de filtro que é feito por meio de revestimento e impregnação de um substrato tecido ou não tecido com uma resina termoendurecível,1 de modo que os fios ou fibras do substrato são encapsulados e ligados em seus pontos de contato. A resina é diluída para menos do que 15 %, por exemplo, 10%, de sólidos, e um modificador de reologia, tal como celulose de hidróxi-etila, é adicionado antes da aplicação. A resina é curada por meio de aquecimento para um valor acima de sua temperatura de cura. A resina pode ser preaquecida para expulsar o solvente após a aplicação, mas antes da cura."PROCESS FOR MANUFACTURING A FILTER MEDIA AND FILTER MEDIA PRODUCED IN ACCORDANCE WITH THIS PROCESS". The invention relates to a filter medium which is made by coating and impregnating a woven or nonwoven substrate with a thermosetting resin, such that the strands or fibers of the substrate are encapsulated and bonded at their contact points. The resin is diluted to less than 15%, e.g. 10% solids, and a rheology modifier such as hydroxy ethyl cellulose is added prior to application. The resin is cured by heating to a value above its cure temperature. The resin may be preheated to expel the solvent after application but before curing.
