Title

Effect of different coating formulation on physical, mechanical, and optical properties of papers made from bleached CMP

Pages

  193-204

Abstract

 In this study, the effect of pigment composition on the properties of paper prepared from bleached CMP pulp was studied. The purpose of this research was to achieve the best combination for coating of the paper to improve physical and optical properties while maintaining strength properties. Three different pigment combinations (100% calcium carbonate (GCC), 70% calcium carbonate and 30% kaolin clay (70GCC30Clay) and 70% calcium carbonate and 25% gritty and 5% titanium dioxide (70GCC25Clay5TiO2)) were made with the addition of anionic starch, latex and dispersant and was used for coating. Physical properties included (surface roughness of the paper, ash content and apparent density) and the optical properties included (brightness, absorption and diffusion coefficient) and paper strength characteristics including tensile strength, bursting resistance, tear strength using standard TAPPI test methods. Factorial design, and analysis of variance was performed and the mean properties values were compared using Duncan's test. By adding clay and titanium dioxide to calcium carbonate, the roughness of the paper surface decreased the highest roughness of the surface of the paper was observed for the control paper and the lowest was seen in the treatment of 70GCC30Clay surface. Also, the highest degree of brightness is related to 70GCC25Clay5TiO2 treatment. The highest tensile strength and burst strength indices were related to gypsum treated paper (GCC) and also the highest tear strength index was measured on treated paper at level 2 (70GCC30Clay).
