Embodiment Construction

[0009] The pulp treatment method provided by the present invention and the coated paper manufacturing method related to the pulp treatment will be further described in detail below with reference to the accompanying drawings and multiple embodiments.

[0010] see figure 1 , the first embodiment of the present invention provides a pulp treatment method, which includes the following steps:

[0011] In the first step, pulp is provided. The pulp can be commercially available hardwood pulp, specifically, eucalyptus pulp, acacia pulp, and miscellaneous hardwood pulp. Of course, the pulp can also be implemented as straw pulp.

[0012] In the second step, compound cellulase is added to the pulp for treatment, and the compound cellulase is a compound enzyme of cellulase and hemicellulase.

[0013] In the composite cellulase, the corresponding enzyme activity ratio of cellulase and hemicellulase is 8:1 to 4:1, and the enzyme activity of the composite cellulase is 4800 HCU / g. In this...

Abstract

The invention discloses a paper pulp processing method. The paper pulp processing method comprises the following steps of: providing paper pulp; and adding composite cellulase into the paper pulp, and processing, wherein the composite cellulase is composite enzyme of cellulase and hemicellulase. The invention also provides a coated paper manufacturing method.

Description

technical field [0001] The invention belongs to the technical field of pulping and papermaking, and in particular relates to a paper pulp treatment method capable of improving the drainage performance of paper pulp and a coated paper manufacturing method related to the paper pulp treatment. Background technique [0002] At present, people's demand for paper is increasing day by day, leading to the shortage of papermaking raw materials, energy shortage and environmental pollution. These problems seriously restrict the development of papermaking industry. [0003] Due to limited timber resources, people are gradually turning their attention to fast-growing, wide-growing hardwoods such as eucalyptus and acacia, or grasses to make pulp. However, the water drainage of hardwood pulp and straw pulp is poor, and the water drainage performance of pulp is one of the important indicators of papermaking performance. Poor performance will bring inconveniences such as low output and high...
