PROCESSO PARA APRODUCAO CONTINUA DE TUBOS DE HIDRATO DE CELULOSE,REFORCADOS COM FIBRAS,BEM COMO DISPOSITIVO PARA A REALIZACAO DO PROCESSO |
摘要 |
Disclosed is a process for the continuous manufacture of fiber-reinforced tubing based on cellulose hydrate, comprising the steps of impregnating and coating fibrous tubing with an aqueous akaline viscose solution; moving the viscose-treated tubing at a steady speed vertically in a straight line along its longitudinal axis; applying a viscose-regenerating fluid along at least one circular circumferential line to at least the outside of the viscose-treated fibrous tubing; immediately after the application step, passing the tubing with the film of regenerating fluid on its surface through at least one first air section, whereby there is produced a fiber-reinforced tubing based on cellulose hydrate; treating the cellulose hydrate tubing with an aqueous fluid containing a dissolved chemical plasticizer; and drying the plasticized tubing. Also disclosed is an apparatus for carrying out this process. |
