Abstract

método de eliminação de defeitos durante o revestimento de extrusão de filme com o uso de controle de velocidade de cilindro de estrangulamento. determinou-se agora que um defeito óptico interno pode ser eliminado mediante o controle da diferente da velocidade relativa entre o clindro resiliente e o cilindro de fundição em um processo de revestimento de extrusão de um filme. em particular descobriu-se que reduzir a velocidade de superfície da cilindro resiliente, em relação ao cilindro de fundição durante o revestimento de um filme orientado biaxialmente, remove o defeito óptico. ao contrário, descobriu-se que aumentar a velocidade de superfície do cilindro resiliente, em relação ao cilindro de fundição durante o revestimento de um filme orientado unixialmente, remove o defeito óptico.
