Abstract

DC60 (26/11/41) dehydrator, uncompressed design Will generate air currents Which can be It can be used to remove water from cellulose membranes. In an energy-efficient manner. In addition, the wet press Can also be modified to produce Economically low density tissue paper with significant energy / cost consumption. More efficient than the entire drying process. For example, cellulose fibers can be removed. The water can be removed in a manner that does not compress. From post-formed toughness to toughness ranging from approximately 25% to water retention toughness by air transmission through fibers with at least 10% or more Energy Efficiency attained by vacuum dehydration. that The same speed in a particular configuration system Might be right Dehydrated in an uncompressed manner to a ductility equal to at least 70% of the water retention stickiness, using approximately 13 horsepower or less per width Of the sheet in inches, or to a toughness equal to at least 80 percent of the water retention ductility, using approximately 30 horsepower or less per inch sheet width, both of which do. Rises at speeds of 2500 feet per minute or more. Dehydration device, uncompressed design It produces air currents that can be used to remove water from cellulose fibers. In an energy efficient manner.In addition, the wet press Can also be modified to produce Economically low density tissue paper with more energy / cost efficiency than the constant drying process, for example cellulose fiber. Can be eliminated The water can be removed in a manner that does not compress. From post-forming toughness to about 25 percent toughness to water retention toughness. By delivering air through fibers with an Energy Efficiency of at least 10% or more achieved using vacuum dehydration at The same speed In a particular skeletal system Might be right Removes water in a manner that does not compress. Until having a toughness equal to at least 70 percent of the ductility in water retention Using approximately 13 horsepower or less per width Of sheet in inches Or to an escape equal to at least 80% of the water retention ductility using approximately 30 horsepower or less per inch width of the sheet, in both cases. It will be done at speeds of 2500 feet per minute or more.

Claims (1)

1. Methods for producing cellulose membranes consist of a) the impregnation of a water-containing suspension of the paper fibers. Accumulates on the endless forming cloth To form a wet pulp where the paper fibers should be tough in Water retention and b) removal of water from the web in an uncompressed manner since its toughness after molding. Its toughness ranges from approximately 25% to the ductility in water retention by means of air through the membrane, with at least 10% more energy efficiency than achieved. By using the dehydration in the tag:
