Hydroxyethyl cellulose*Papermaking

The papermaking industry is an important industry, and hydroxyethyl cellulose (HEC), as a common thickener, plays an important role in the papermaking process.

1. Hydroxyethyl cellulose can increase the viscosity of papermaking pulp and retain moisture. In the process of pulping and papermaking, adding an appropriate amount of hydroxyethyl cellulose can make the pulp more evenly distributed on the net, and can effectively adsorb on the surface of lignin particles, thereby improving the binding force between the pulp and water, reducing water loss, and helping to improve the yield and product quality.

2. Hydroxyethyl cellulose also has good protective colloid properties. Due to its strong adsorption properties and porous structure, it can form a uniform, dense, soft, breathable and not easy to break or deform film in the papermaking process. Cover the surface of the original ecological suspension agglomerate, and wrap the suspension agglomerate particles to conceal them, so as to prevent the suspension agglomerate particles from contacting each other and undergoing cross-linking reactions, prevent the suspension agglomerate particles from being polluted and damaged by the external environment, and extend the service life.

3. Adding an appropriate amount of hydroxyethyl cellulose can also improve the quality of papermaking. It can not only enhance the coiling force between the base and the surface, as well as between the same base or surface; it can also significantly improve the base tension index value; in addition, it can also significantly improve the color saturation of printed graphics; thereby greatly improving the overall visual experience of the product; at the same time, it can also greatly reduce the operating pressure of machinery and equipment; thereby achieving the goal of saving resource consumption.

4. Adding an appropriate amount of hydroxyethyl cellulose in the papermaking industry plays a positive role in increasing production capacity, improving product quality and saving resources.
