Pulp is an important material required for papermaking. Commonly used raw materials include wood, bamboo, wheat straw, straw and other cellulose-based simple substances and recycled chemical cellulose fibers such as waste paper. In the process of making paper, pulp needs to be processed first, including steps such as crushing, cleaning, cooking, bleaching and pulping, and then the finished paper is obtained through processes such as screening and pressing. A large amount of foam is likely to be generated in these processes. Nanhui's pulp defoamer agent can effectively solve the foaming problem in pulp production.
Why eliminate foam in pulp?
1. Affect product quality: Foam can affect the quality of pulp, papermaking equipment, and finished products. If too much foam is generated and enters the subsequent processing process, it will pollute the pulp, and even affect the gloss, smoothness and other appearance indicators of the paper, resulting in The quality of the product is reduced.
2. Reduce production efficiency: Too much foam will lead to clogging of paper machine tank chimney and filter, resulting in abnormal operation of equipment, increasing maintenance time and cost, and also making pulp processing more difficult and reducing production efficiency .
3. Pollution of the environment: Since the foam usually absorbs a lot of impurities, such as pigments, resins, etc., if the foam overflows the container, it will pollute the working environment.
What are the functions of pulp defoamer:
1. By inhibiting the generation and diffusion of foam, controlling the impact of foam on pulp and papermaking equipment, improving the stability and uniformity of pulp liquid, thereby improving the quality, gloss and flatness of paper.
2. By controlling the formation and diffusion of foam, reduce the content of organic matter and chemical elements such as nitrogen and phosphorus in wastewater, reduce the discharge of pollutants, and reduce environmental pollution.
3. It can effectively reduce the splashing phenomenon that may occur when the closed cylinder liquid is located above the foam, and prevent workers from being scalded.
