摘要

The pulping characteristics of the branches of triploid P. tormentors Carr. (hereinafter referred to as "triploid PTC")and P Nigra Italic (herein after referred to as "PAT"), as well as the bleachability of the pulps of the branches, were studied. The chemical compositions of both materials were analyzed. No substantial difference in chemical compositions between the branches was found. Hollocellulose and lignin contents of the branch of triploid P. tomentosa Carr. were slightly higher than those of the branch of P. Nigra Italic. Lignin and extractives of the branches were higher than those of stem woods. NaOH-AQ pulping was carried out at various pulping conditions. The results obtained under the optimuM pulping conditions indicated that the Kappa number and screened pulp yield were about 31.6 and 50.6% for the branch of triploid P. tormentors Carr., and 27.9 and 49.1% for the branch of P. Nigra Italic, respectively. The brightness resulting from the process of CEHP reached 76% ISO for the pulp of the branch of P. Nigra Italic and 83% ISO for the pulp of the branch of triploid P. tormentors Carr.. The bleached pulps can be used to substitute the commercial HBKP in producing offset paper.

Nigra Italic的分支略高。分支的木质素和提取物高于茎木。 NaOH-AQ制浆在各种制浆条件下进行。在最佳制浆条件下获得的结果表明，三倍体折磨假单胞菌Carr。的分支的Kappa数和筛分的纸浆产率分别为31.6和50.6％，黑斜纹假单胞菌的分支的Kappa数分别为27.9和49.1％。 CEHP工艺产生的白度为P. Nigra Italic分支的果肉达到76％ISO，三倍体P. tormentors Carr。的分支的果肉达到83％ISO。商业HBKP生产胶版纸。
