羧甲基纤维素是一种纤维素的衍生物,在涂布纸与纸板的生产中它作为优良的保水剂,也可作为辅助胶粘剂。众所周知,涂布纸从涂布到干燥过程中不可避免地存在着胶粘剂的再分配问题—迁移现象。粘合剂迁移的结果对纸张的印刷效果有着致关重要的影响。CMC优良的保水性可有效地阻止胶粘剂不适当的迁移,改善纸张涂层对油墨的吸收性,避免印刷斑点,提高涂层强度。CMC所制涂料固含量高,流变性能好,在刮刀涂布中应用可减少刮刀条痕,提高涂布质量,有润滑刮刀的作用,延长刮刀的使用寿命,在气刀涂布中应用可提高
Carboxymethyl cellulose is a cellulose derivative that acts as an excellent water-retaining agent in the production of coated paper and paperboard, and can also be used as an auxiliary binder. As we all know, coated paper from drying to drying process inevitably exists the problem of redistribution of adhesive - migration phenomenon. The result of adhesive migration has a crucial effect on the printing quality of the paper. CMC excellent water retention can effectively prevent the improper migration of adhesive, paper coating to improve ink absorption, to avoid printing spots, improve the coating strength. CMC coatings made of high solid content, good rheological properties, the blade coating can be applied to reduce scraper marks, improve coating quality, the role of a lubricant scraper, extend the life of the scraper, air knife coating can be applied to improve
