制浆,是决定纸张质量的重要环节。化学法制浆,是利用化学药品的水溶液在一定温度和压力下处理植物纤维原料,使原料纤维彼此分离成浆。最早采用化学制浆方法是亚硫酸制浆法,后经工艺技术的不断改进,化学制浆的工艺技术日益科学,适用范围日益广泛,废物回收技术日益完善,环保理念日益丰富,使化学制浆法具备其它方法无法媲美的优势。
Pulping is an important part of the quality of the paper. Chemical pulping, is the use of chemicals in aqueous solution at a certain temperature and pressure processing of plant fiber raw materials, the raw fibers separated from each other into a slurry. The earliest use of chemical pulping method is sulfite pulping method, after continuous improvement of process technology, chemical pulping process technology increasingly scientific and wider scope of application, waste recycling technology is increasingly perfect, the concept of increasingly rich environmental protection, chemical pulping Law has the advantage of other methods can not be comparable.
