该文采用动态干燥模拟器.对添加了胶粘物的漂白硫酸盐浆纸幅如何从烘缸上分离进行了研究。胶粘物的存在提升了黏附功(the work of adhesion),进而带来了运行问题。提升入口纸幅的固含量和干燥温度可以改善纸幅的剥离性能。同时,该文采用静态干燥模拟器进行粘缸测试。对静态干燥模拟的研究表明:虽然硫酸盐浆纤维纸幅比新闻纸纤维保留的胶粘物要少,但是在金属干燥表面释放的胶粘物比例仍然较高。使用新闻纸进行静态测试中,由于木素和胶粘物的亲和力,所以从纸胎(mat)转移到金属表面的多数胶粘物伴随有纤维。
In this paper, a dynamic dry simulator was used to study how the bleached kraft pulp web with the addition of stickies was separated from the dryer. The presence of stickies enhances the work of adhesion, leading to operational problems. Increasing the solids content and drying temperature of the inlet web improves the release properties of the web. In the meantime, this paper uses a static dry simulator to test the viscous tank. Studies of static drying simulations have shown that although the kraft pulp fiber web retains less stickies than the newsprint fiber, the percentage of stickies released on the metal drying surface is still high. In static tests with newsprint, most of the stickies transferred from the mat to the metal surface are accompanied by fibers due to the affinity of the lignin and the stickies.
