新型微聚合物技术在提高木浆和非木浆滤水和留着方面的应用

New micropolymer technologies for increased drainage and retention for both wood and non wood containing furnishes

新一代阳离子和阴离子微聚合物(Micropolymer)已经问世。这种微聚合物不含挥发性有机化合物(VOC)和烷基酚聚氧乙烯醚(APE)。将这种新的微聚合物与线型的聚丙烯酰胺一起使用或者和无机微粒技术(如胶体硅和可润胀矿物质)协同使用,可以显著提高滤水、纤维留着和灰分留着。这种协同使用适合用于原料为木浆或非木浆的高加填文化纸、超级压光纸和低加填的新闻纸。尤其是当阳离子微聚合物与聚丙烯酰胺一起应用在未漂包装纸种的生产中时,会显著提高滤水性能。

A new generation of both cationic and anionic micropolymer technologies has been developed.These water based chemistries are volatile organic compound （VOC） and alkyphenol ethoxylate （APE） free. When these novel micropolymers are applied with linear poly-acrylamide or in conjunction with inorganic microparticle technologies （such as silica or swellable minerals）, substantial increases in drainage, fibre retention and ash retention are observed. These improvements have been observed not only in high filled wood and non wood containing grades such as fine paper and super calendared sheets （SCA）, but also in low filled newsprint grades. Of particular note is the drainage improvement seen with the application of the cationic micropolymers in unbleached packaging grades with polyacrylamide.
