Pulp cleaning agent, pulp manufacturing method and pulp cleaning method |
| abstract |
The purpose of the invention is to provide a paper pulp cleaning agent extracting lignin fully from paper pulp raw material, a paper pulp preparing method, and a paper pulp cleaning method. A chelated compound and a water-soluble polymer are contained with effective quantity according to the paper pulp cleaning agent of the invention. Lignin extraction can be improved through adding the paper pulp cleaning agent into a clean area (212) and a paper pulp cleaning part (30). The paper pulp cleaning agent is preferable to be added to the upstream side of the clean area (212) and the paper pulp cleaning system (30), and the addition rate of the water-soluble polymer related to the chelated compound is increased. |
