In paper production, there is an additive that is indispensable and irreplaceable and plays an important role. It is PAM polyacrylamide, which is used as a retention aid in papermaking.

During the papermaking process, fibers and fine particles are easily lost, resulting in a decline in paper quality. Using polyacrylamide as a retention aid can effectively improve the retention rate of fibers and fine particles in paper, thereby improving the quality of paper.

Polyacrylamide (pam) is a linear polymer with the advantages of good solubility and high molecular weight. It is a commonly used additive in the paper industry to reduce fiber flocculation and improve paper formation. The application effect of polyacrylamide in the paper industry is mainly determined by molecular weight, charge density, ionization degree and functional group activity. Cationic polyacrylamide is used as a retention and filter aid in the wet end of the paper machine, which can improve the uniformity of the paper and the dewatering performance of the slurry. It can also improve the retention rate of fine fibers and fillers and reduce raw material consumption.

Principle of use:

The principle of use of polyacrylamide is to directly adsorb on negatively charged fibers, small fibers and fillers. In addition to retention aids and filter aids, it is also the best representative of humidification enhancers. Can be used in acid sizing and neutral sizing papermaking systems. This product is used in the production of writing and printing, newsprint, offset paper, paper with mechanical pulp and boxboard, letterpress and corrugated board. Usually added after the pressure screen of the paper machine, the dosage is 0.01%-0.03% (according to the output (calculation)); it can be used as a monomer, dimer or granular retention aid, and can also be used as a flocculant to improve the efficiency of the paper machine. White water recovery rate. efficiency.

Usage:

Cationic polyacrylamide is used in paper industry. The main component is polymer electrolyte, which is used to improve the retention of fiber and ash during the papermaking process. When added to paper pulp, this product produces excellent retention and drainage effects while maintaining good paper uniformity. This product can produce a synergistic effect when used in conjunction with other additives such as organic particles or/and color fixing agents.

Properties:

Cationic amides are used as retention aids in the wet end of paper machines. When used as a retention aid, it has the characteristics of low dosage and significant effect. It can also be used in acid sizing and neutral sizing papermaking systems. Cationic PAM utilizes the bridging flocculation effect to significantly improve the retention rate of fillers and fine materials during the papermaking process and accelerate the water filtration of paper materials in the mesh of the paper machine. In the granular system, adding cationic PAM can form large flocs, thereby improving the uniformity and quality of the paper.

Polyacrylamide has become one of the indispensable and important chemicals in modern papermaking technology. At the same time, the polyacrylamide produced by Hengfeng Chemical can also be customized according to different needs to meet the needs of different customers.

How does Retention Aid improve the retention of fibers and chemicals?
Retention aid is a crucial component in the papermaking process, playing a key role in improving the retention of fibers and chemicals. The primary objective of Paper Making Retention Aid is to enhance the efficiency of paper production by preventing the loss of valuable materials during various stages of the manufacturing process.
Mechanism of Action:Retention aid operates through a combination of mechanisms that contribute to the effective retention of fibers, padding, fiber fines, and other chemicals used in the papermaking slurry. One of the key functions is its ability to act as a flocculant, promoting the aggregation of fine particles into larger, more easily retained flocs. This aggregation prevents the dispersion and subsequent loss of these particles during drainage and formation of the paper sheet.
Flocculation and Particle Retention:The flocculation process involves the binding together of individual particles, creating larger clusters that are less prone to being washed away. In the context of papermaking, this is particularly important during the formation of the paper sheet on the paper machine. Retention aid facilitates the formation of well-structured flocs that entrap fibers and other components, preventing their escape with the water.
Creating a Stable Environment:Retention aid contributes to the establishment of a clean and steady wet chemical environment within the papermaking system. By stabilizing the dispersion of particles and preventing their unwanted migration, it ensures a consistent and controlled environment for the paper-forming process.
Reducing Chemical and Fiber Loss:Through effective flocculation and stabilization, retention aid minimizes the loss of fibers and chemicals. This has significant implications for both cost reduction and environmental impact. Lower chemical and fiber consumption translates to reduced production costs, as fewer raw materials are required to achieve the desired paper quality.
