一种复合打浆酶在水松原纸中的应用

The Invention Relates to the Application of a Compound Beating Enzyme in Larch Base Pape

当前造纸行业竞争激烈,除了市场对产品质量的要求不断提高外,浆价的上涨也导致各生产企业利润的降低,当前各生产企业均在积极寻找降低生产成本的方法,打浆酶作用机理是通过对纤维进行改性,对纤维末端进行处理,促进纤维的润胀,使纤维表面和末端的羟基和羧基增多,从而提高纤维之间的结合力,达到提高纸张性能,改善纸页品质的作用;并且通过对纤维内部进行分解,促进打浆过程中的分丝和帚化,使打浆变得相对容易,节约打浆能耗。研究结果结果表明,采用打浆酶进行打浆是可行的,且成本节约较明显,对成纸指标也有一定的积极作用,但加量不宜过大,否则会对纸面状态及系统造成负面影响。

At present, the paper industry is facing fierce competition. In addition to the continuous improvement of the market's requirements on product quality, the rise in pulp price also leads to the reduction of profits of all production enterprises. Currently, all production enterprises are actively looking for ways to reduce production costs. The action mechanism of beating enzyme is to modify the fiber, treat the fiber end, promote the swelling of fiber, increase the hydroxyl and carboxyl groups on the fiber surface and end, so as to improve the binding force between fibers, improve the paper performance and improve the quality of the paper. And through the fiber internal decomposition, promote the pulping process of silk and broom, pulping becomes relatively easy, save energy consumption. The research results show that the use of beating enzyme for beating is feasible, and the cost saving is obvious, and has a certain positive effect on the paper index, but the amount should not be too large.
