Effects of Cleaner Papermaking Additives WEC on Sizing Degrees in Neutral Papermaking with Mechanical Pulp

Abstract:

Influences of self-developed additives WEC02/WEC03 on sizing of mechanical pulp are analyzed in this study. The results indicated that the optimal dosage for paper sizing were 0.2% (w/w) for WEC02, with sizing degree of 33 s, and 0.8% for WEC03, with sizing degree of 52 s. In addition, the combined usage of WEC02 (0.2%) and WEC03 (0.6%) at pH7.0 could get better sizing performance than single application of WEC02 or WEC03 with sizing value of 77 s. It is obvious that WEC02/WEC03 have great potential to improve sizing efficiency in neutral paperrmaking, leading to saving the sizes dosage and cutting down the production cost.
