采用干法工艺,利用半沸腾旋转式反应器,在碱(酸)催化作用下,将普通天然淀粉改性,使其结合阳离子官能团、阴离子官能团及近似中性的官能团并最终控制产品呈阳离子型,制成造纸用多功能助留增强剂。多家纸厂使用情况表明,该助剂与阳离子淀粉相比,可明显提高成纸物理强度和细小纤维与填料的留着率,并且能够显著改善成纸表面性质。
Using a dry process, using a semi-boiling rotary reactor, the common natural starch is modified under alkaline catalysis to incorporate cationic, anionic, and nearly neutral functional groups and ultimately to control the product to be cationic , Made of paper with a multi-function retention enhancer. The use of a number of mills shows that the additives, compared with cationic starch, can significantly increase the physical strength of the paper and the retention of fines and fillers, and can significantly improve the surface properties of the paper.
