Application analysis of defoamer for paper color pulp
Color paste is one of the key raw materials in the process of making paper. It is a mixture of cellulose, fillers, additives, etc.
Cellulose is the most important component in papermaking process. It is used to improve the gloss, strength and printability of paper. In order to solve this problem, scientists and engineers have developed a paper color pulp defoamer. Paper color pulp defoamers have excellent defoaming effect, they can destroy the surface film in the foam and make it break, and reduce the formation and accumulation of bubbles in the liquid. By changing the surface tension and viscosity of the liquid, defoamer can prevent the entry of air and effectively reduce the formation and durability of foam. In addition, the defoamer can improve the stability of the color paste, prevent the deposition and aggregation of particles, and make the color paste suspension more uniform and stable.
The defoamer is widely used in every link of paper industry.
1. In the process of pulp preparation, by adding proper amount of defoamer, the formation of foam can be effectively reduced, and the introduction of air bubbles in the process of stirring can be reduced, so the quality and stability of pulp can be improved.
2. In the process of pulp transportation and filtration, the use of defoamer can prevent the clogging and erosion of foam equipment, improve the process reliability and stability. 3. In the paper coating and printing process, the application of defoamer can also reduce the foam on the surface of paper, improve the coating and printing effect. The amount of defoamer should be controlled reasonably, and proper amount of defoamer should be added without affecting the paper quality, so as to avoid other problems caused by overuse. Finally, regularly check and evaluate the effect and performance of defoamer, according to the actual situation to adjust and improve to ensure its continued effectiveness.
