| Abstract: | Analysis of common paper making fillers indicated that
TiO2 (Anatase) has highest negative charge whereas GCC has slightly positive
charge. Hypo chlorite bleached pulps have higher negative charge than pulps
obtained by other bleaching sequences employed by paper mills. Increment in
negative surface charge in pulps caused negative effect on filler retention, specific
scattering co-efficient and print density of paper, however print through
tendency increased causing poor print quality. |
