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. ©KIPO&WIPO 2008

본 발명은 (a) 종이 원료 시스템을 제공하는 단계; (b) 고전단력이 없을 때 알케닐 숙신산 무수물 성분을 포함하는 수성 사이징 에멀션을 형성하는 단계; (c) 단계 (b)로부터 형성된 에멀션에 대해, 고전단력의 부재시에 개선된 사이징 효능을 가지는 후-희석된 에멀션을 생성하는 조건하에서, 양이온성 성분의 존재하에 후-희석을 수행하는 단계; (d) 후-희석된 에멀션을 종이 원료에 첨가하는 단계; 및 (e) 종이 웹을 형성하는 단계로 이루어지는 종이 제품을 사이징하는 방법에 관한 것이다.
