Abstract

This study was aimed to investigate the effect of different charges of SODIUM SILICATE on CHEMICAL DEINKING of OLD NEWSPAPER. CHEMICAL DEINKING process was accomplished with 1% hydrogen peroxide, 1% sodium hydroxide, 0.3% DTPA and 0.15% surface active agent at different charges of 0, 1, 2 and 3% SODIUM SILICATE on the basis of oven dry waste paper. The results of the OPTICAL PROPERTIES of produced paper showed that the brightness of paper improved (50.9%) and the yellowness decreased (11.33%) with increasing of SODIUM SILICATE charge to 2%. Increasing of SODIUM SILICATE use from 0.3% did not indicate significant effect on opacity values. The highest opacity (98.8%) was achieved by 1% SODIUM SILICATE. The results of the PHYSICAL PROPERTIES indicated that increasing of SODIUM SILICATE use up to 2% resulted the paper with the highest bulk (2.75 cm3/g). Totally, the consequences of this research in relation to CHEMICAL DEINKING of OLD NEWSPAPER at different charges of SODIUM SILICATE showed that use of 2% SODIUM SILICATE would lead to produce the paper with higher brightness, caliper and bulk along with desirable opacity.
