Definitions
- Chemical mechanical pulp is a method of separating fibrous raw materials by chemical, thermal, mechanical methods or a combination of the three. Chemical mechanical pulp is mainly used in the intercellular layer due to the exfoliation of lignin by chemicals such as alkali. The long fibers are high and the content of fine fibers is low, and the lignin content is high, and the light scattering coefficient is high. Chemical mechanical pulp is used as a supplement to pulp raw materials, and the effective utilization of wood scraping corner scrap has certain potentials for development and application in the pulping industry.
- the present invention is a chemical pulping method developed based on the above basics. This method inherits the technical characteristics of one of the four ancient inventions of papermaking, combined with the research results of our previous strong alkali pulping, not only greatly improved the pulping efficiency, but also made the pulp reach the yield close to the mechanical pulp, and at the same time Minimizes fiber breakage and maintains fiber strength. Summary of the invention
- the bursting index was 2.39 kPa-m 2 /g
- the folding resistance was 54 times
- the tensile index was 26.9 Nm/g
- the tear index was 15.1 mN-m 2 /g
- the filtrate COD was 80400
- the pH was 9.82.
