Title
(EN) Reduced shear cellulose reactive sizing agent for wet end applications
(ZH) 应用于湿端的低剪切纤维素反应型施胶剂
Abstract
(EN)
The invention relates to a method for sizing a paper product that involves the steps of (a) providing a paper stock system; (b) forming, in the absence of high shearing forces, an aqueous sizing emulsion comprising an alkenylsuccinic anhydride component; (c) submitting the emulsion formed from step b to a post-dilution step in the presence of a cationic component under conditions, in the absence of high shearing forces, that produce a post-diluted emulsion having improved sizing efficacy; (d) adding the post-diluted emulsion to the paper stock; and (e) forming a paper web.

(ZH)

本发明涉及一种对纸品施胶的方法,其包括:(a)提供纸浆系统;(b)在不使用高剪切力条件下,形成含烯基琥珀酸酐组分的水性施胶乳液;(c)对步骤b形成的乳液进行后稀释工序,该工序中存在阳离子组分,不使用高剪切力,使用的工艺条件使所得后稀释乳液的效能改善;(d)将后稀释乳液加入纸浆中;以及(e)形成纸网。
