Title
(EN) PROCESS FOR PRODUCTION OF FILM OR COATING COMPRISING CELLULOSIC NANOMATERIAL
(FR) PROCÉDÉ DE PRODUCTION DE FILM OU DE REVÊTEMENT COMPRENANT UN NANOMATÉRIAU CELLULOSIQUE
Abstract
(EN)
The present invention is directed to a process for manufacturing a film or coating comprising high amounts of cellulosic nanomaterial. According to the present invention, a screen printing press, such as a rotary screen press, is used to create a film or coating comprising cellulosic nanomaterial. One benefit of the present process is that the suspension used in the printing process has a high dry content and high viscosity, thereby facilitating the process for manufacturing a film or coating comprising high amounts of cellulosic nanomaterial.
(FR)
La présente invention concerne un procédé de fabrication d'un film ou d'un revêtement comprenant des quantités élevées d'un nanomatériau cellulosique. Selon la présente invention, une presse à sérigraphie, telle qu'une presse à cadre rotatif, est utilisée pour créer un film ou un revêtement comprenant un nanomatériau cellulosique. Un avantage du procédé selon la présente invention est que la suspension utilisée dans le procédé d'impression a une teneur en matières sèches élevée et une viscosité élevée, ce qui permet de faciliter le procédé de fabrication d'un film ou d'un revêtement comprenant des quantités élevées de nanomatériau cellulosique.
