Abstract

TECIDO COM PROPRIEDADES FILTRANTES APRIMORADAS PAR A FILTRAÇÃO DE GASES QUENTES E SACO FILTRANTE. Tecido filtrante que apresenta propriedades filtrantes para filtração de gases quentes contendo uma manta de aramida não tecida. A manta apresenta um peso base de pelo menos 9,7 onças por jarda quadrada (330 gramas por metro quadrado) e é caracterizada por uma distribuição de tamanho de poro na qual o número de poros em uma certa faixa conforme medido pelo método de teste ASTM F316-03 é lotado contra o tamanho de poro. Em uma concretização preferida, a porcentagem de poros que apresentam um tamanho entre 10 e 26 (Mi)m é superior a 50%, enquanto a porcentagem de poros que apresentam um tamanho superior a 50 (Mi)m é menos de 0,5%.
