The Effect of Nanoclay Montmorillonite on Properties of Paper From CMP Pulp

This study aimed to investigate the effect of nanoclay on physical, mechanical, optical properties and morphological characteristics of the paper from CMP pulp was performed. The amount of nanoclay in six levels of 0, 2, 4, 6, 8 and 10 percent and for retention of the cationic starch 1 percent of all pulps used. After the addition of additives, the handsheets was 60 g/m2 and the physical, mechanical, optical properties and morphological papers made was examined. The results showed that with the increase of nanoclay to 2% increase of the tensile strength and up to 10% reduced. With increasing nanoclay to 4% roughness increase and with 10% reduced. Decreasing trend in average tear strength, burst strength and brightness with nanoclay increasing to the level of 10% was observed. Uptrend in average air resistance, opacity and yellowness by increasing nanoclay the level of 10% was observed. SEM images showed that with increasing levels of nanoclay, somewhat coarse fibers by nanoclay pores are filled why increased air resistance. XRD results showed that the peak of the crystalline area disappeared and morphology of the intercalation formed.
