GROUND PAPERS USED TO MANUFACTURE TAPES TO COVER JOINTS BETWEEN FACING SHEETS

摘要

FIELD: construction.;SUBSTANCE: ground contains cation water-fast additive, alkaline glueing agent and anion activator in specified amount. Anion activator it contains is a component selected from group, including polyacrylate, sulfonate, carboxymethylcellulose and galactomannan hemicellulose. Ground paper has pH from approximately 7.0 to approximately 10, and strength of internal link from approximately 25 to approximately 350 millifeet per pound per square inch. This ground paper is produced by contact of a certain amount of cellulose fibres with water-fast additive, alkaline gluing agent and anion activator, serially and/or simultaneously.;EFFECT: improved physical properties of ground paper and expanded assortment of paper tapes to cover joints.;22 cl, 1 dwg, 1 ex
