在Lyocell技术中,原液的综合特性是非常重要的。激光衍射法对颗粒的分析是微型照片和流变学分析方法之外的一种对纤维素/NMMO溶液溶解状态的描述方法。——微小粒径,微型照片法; ——亚微小粒径,激光衍射法; In Lyocell technology, the comprehensive nature of the stock solution is very important. The laser diffraction method for particle analysis is a method of describing the dissolution state of the cellulose / NMMO solution in addition to the micro photo and rheological analysis methods. - small particle size, micro photo method; - submicron particle size, laser diffraction method;
