ABOUT THE POSSIBILITY COATING OF PAPER IN THE PROCESS OF AERODYNAMIC FORMING
Abstract
Forming a paper web by an aerodynamic method is carried out by deposition of fibers and paper components from a stream of air on a forming wire. Necessary properties of written and printed types of paper are ensured by the introduction of mineral fillers into the composition of the paper. The method used allows you to enter the filler both in the process of forming a fibrous layer, and as a coating on one side of a sheet of paper. Mineral fillers improve the printing properties of the paper, but reduce the strength of the paper.
The analysis of the negative effect of the filler on the tensile strength of paper was carried out. The theoretical understanding of the mechanism of retention of filler in the structure of the paper web are given. The dependences of the degree of retention of the filler on the specific weight of the fibrous layer and the diameter of pores in the paper web are considered. The main factor in the retention of the filler in the process of surface coating is the ratio of the average particle diameter of the filler and the diameter of the through interfiber pores. These data can be used in experimental and practical work with new types of fillers, with natural and synthetic fibers.
With the method of aerodynamic molding, paper samples were obtained when the filler was applied both to the structure and to the surface of the paper web. To increase the adhesion strength, the surface of the filler particles is modified with a solution of Na-carboxymethyl-cellulose. A comparative assessment of coated paper samples from various wood species by optical indicators, values of roughness and air permeability values of paper is given. A method for introducing a filler into the paper structure during aero molding is proposed. The developed method of paper coating in the process of aerodynamic formation can be applied in the manufacture of printing paper and containerboard.
