【摘要】 <正> 前言 广东省竹类纤维资源丰富,现有竹林面积约600多万亩,大部分分布在肇庆、梅县、韶关、惠阳等地区,其中广宁县有竹林70万亩。广东省气候温和、雨量充沛,适于竹子生长,一般三年左右即可采伐。每公顷竹材收获量比针、阔叶林高6—7倍。随着塑料、钢铁工更多还原

【Abstract】 Factors affecting the yields and the Kappa numbers of unbleached bamboo pulps were investigated. The factors studied were alkaline charge, sulfidity, maximum cooking temperature, and time at temperature. Bamboo species concerned were Bambusa textilis McClure, Dendrocalamus latiflorus Munor and Ar-undinaria amabilis McClure. Results indicate that alkali charge is the most important factor. Kraft pulping results of these three bamboo species were compared. Bambusa textilis McClure and Dendrocalamus latiflorus Munor seemed to give better paper quality.Results obtained in this experiment suggest that the max. temperature period on kraft bamboo pulping could be reduced to 0.5 hour. Guangning Paper Mill, Guangdong Province, adopted the results of this investigation and had reduced its cooking duration of bamboo kraft pulping at 168℃ from 1 hour to 0.5 hour since August, 1984 and satisfactory results were obtained.更多还原
