两性聚丙烯酰胺干强剂在牛皮箱板纸机上的应用

Application of Amphoteric Dry-strength Agents on Kraft Liner Machine

生产原料中二次纤维的大量使用，严重影响了成纸的强度。景兴纸业股份有限公司通过在PM10中添加两性聚丙烯酰胺（AmPAM）干强剂，不仅维持了纸张强度，而且还提高了纸料的留着率，改善了滤水，提高了纸张灰分。

The use of a large number of secondary fibers,seriously affects the strength of paper. By using amphoteric dry-strength agent, Jingxing PMIO not only maintains the strength of the paper, but also improves the retention drainage , and paper ash content.
