Title:
PROCESSING TECHNOLOGY FOR REMOVING ADHESIVE SUBSTANCES FROM PAPER PULP
Document Type and Number:
WIPO Patent Application WO/2021/057159
Kind Code:
A1
Abstract:
The present invention relates to the field of paper pulp processing. Disclosed is a processing technology for removing adhesive substances from paper pulp. A preparation method mainly comprises: first performing heat dispersion on a pulp, diluting same, and adding cleaning enzymes, before milling and pulping, and then adding cationic organic polymers to obtain processed pulp. In the method, the combining of biological enzymes and cationic organic polymers is used to effectively control the negative impact that adhesive substances in waste paper pulp have on production, and the obtained product is of quality high. During the preparation process, no pollution is generated, the energy consumption is low, the operation is simple, and the removal effect of adhesive substances is obvious. The processing technology may be applied to industrial production and has good application prospects.
