Abstract: Compared with APMP and HBKP, the BECMP wet-end chemistry characteristics including fines content, Zeta potential, water retention value, carboxyl group content and DCS content were investigated. The results showed that BECMP had some inherent characteristics of high yield pulp, such as higher contents of fines, DCS, as well as carboxyl groups. Meantime, AKD sizing of BECMP was investigated, and the results showed that the sizing effect of BECMP was better than that of HBKP and APMP when the AKD dosage was over 0.2%. Fines and DCS of BECMP had negative effect on AKD sizing, but it was smaller than APMP.
