Title

Effect of calendering on physical and mechanical properties of coated papers

Pages

  273-285

Abstract

 The purpose of this study was to improve the properties of the coated papers by paper/calendering/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">calendering. Two types of printing and writing paper (75 and 125gsm) and five coating suspensions (the first suspension with 22. 9% binders and 50% solids content, the second with 24. 73% binders and 50% solids, the third one with 22. 9% binders and 30% solids, fourth suspension with a 24. 73% binders and 30% solids and the fifth suspension with 42. 3% binders and 50% solids content) were used. The coatings were composed of 80% kaolin clay, 20% ground calcium carbonate, dispersant and different ratios of polyvinyl acetate and lactic acid. The base and coated papers were dried after coating. The paper/calendering/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">calendering treatment was carried out at a temperature of 55° C and 60 kg/cm linear pressure. Air resistance, thickness, water absorption, tearing resistance and bursting strength of papers were determined. The paper/calendering/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">calendering operation was effective in reducing the thickness and increasing the air resistance. Water absorption was decreased only in 75gsm samples. As a result of calendaring, the mechanical properties were improved slightly, but in most cases, this treatment had an adverse effect on the mechanical indexes.
