In the bleaching of E. Urpphylla kraft pulp with Z 1Z 2P bleaching process, total ozone 1.7% and 2.0% hydrogen peroxide are being charged, the pulp brightness of 87.6%(SBD) is claimed for, and when the ZEpP sequence is employed for the same species with 1.2% ozone, 1.0% NaOH and 1.5% hydrogen peroxide, the pulp are being bleached to 84.8%(SBD) brightness. Although the viscosities of the pulps bleached with the both processes are lower than that bleached with conventional CEHP process, the comparable strength properties can be observed. IR analysis shows that the crystallinity index of the bleached pulp is lower than that of unbleached pulp. Electronic microscope observation of a number of the ozonated fibres reveals the existence of ridges and valleys on the structural surfaces.

对尾叶桉改良硫酸盐浆采用Z1Z2P流程漂白,O3总用量17%,H2O2用量20%,可漂至876%白度。采用ZEpP流程漂白,O3用量12%,NaOH用量10%,H2O2总用量15%,可漂至848%白度。虽然纸浆粘度较低,但其强度略优于CEHP漂白浆。IR分析表明:臭氧漂白引起纤维素结晶指数下降。电镜显示:臭氧漂后,纤维表面出现明显的峰和谷。

Four Modified kraft (extended delignification) pulpings of plantation eucalyptus wood were carried out in laboratory. The results demonstrate that modified kraft pulping has higher pulping selectivity than conventional kraft pulping. Modified kraft pulping can produce very low Kappa number pulp with good pulp strength. Compared with the conventional kraft pulp, the Kappa number of modified kraft pulp of eucalyptus wood is 5~6 units lower, but its viscosity is more than 2.8 mPa·s higher. Modified kraft pulp...

Four Modified kraft (extended delignification) pulpings of plantation eucalyptus wood were carried out in laboratory. The results demonstrate that modified kraft pulping has higher pulping selectivity than conventional kraft pulping. Modified kraft pulping can produce very low Kappa number pulp with good pulp strength. Compared with the conventional kraft pulp, the Kappa number of modified kraft pulp of eucalyptus wood is 5~6 units lower, but its viscosity is more than 2.8 mPa·s higher. Modified kraft pulp has higher yield and lower rejects than its corresponding conventional kraft pulp. However, due to the slow reaction, modified kraft pulping needs greater H_factor value than conventional kraft pulping to achieve a given Kappa number.

Laboratory modified kraft pulping (extended delignification) of Pinus elliottii and Pinus caribaea as well as its principles were studied. It was discovered that the modified kraft extended pulping process (MK) had a higher pulping selectivity than the conventional kraft cooking process (CK). Compared to the CK pulps, MK pulps had similar screened yield, lower rejects and higher viscosity at the same kappa number. And they showed a better tear strength at the same tensile.
