摘要
本文利用直接湖蓝6B染料用染色法测定三种速生材木浆纤维的表面积.用丝光化方法和超声波技术对漂白桉木硫酸盐浆进行了活化处理,研究活化处理对纸浆纤维比表面积和保水值的影响.研究结果表明,染色法是一种操作简单方便、有效的测定纸浆纤维表面积的方法;超声波处理及丝光化处理可以显著提高纤维素纤维的表面积和对试剂的可及度.
The surface area of three kinds of bleached fast - growing wood pulp fibers was determined by the method of dye adsorption with C. I. Direct blue 1 ( Direct sky blue 6B ) . The surface area and water retention value (WRV) of the bleached sulfite pulp fibers from Europhylla after or before being treated by the ultrasonic and mercerized in the slack, were also studied. From both the dye adsorption and WRV data, it was concluded that the accessibility of the pulp fibers was improved by both such treatments.
