The working process of the powder surface modification machine usually involves sending the powder raw materials through the feeding and conveying system.In the modification chamber., during the conveying process, the powder is heated and dried. At the same time, the modifier isatomized and sprayed into the modification chamber.This allows it tofully mix with thematerial.In the high-speed operating modification chamber,the material is subjected to impacts, friction, shear, and other effects, allowing the powder particles to fully contact and mix with the modifier, thereby achieving the coating modification of the powder.This is an empty input.

1.The role of the powder surface modification machine in the fine processing of paper fillers.

  1. Improving the compatibility between fillers and paper fibers.: The compatibility between unmodified paper fillers and paper fibers is poor, which affects the strength and uniformity of the paper. The powder surface modification machine treats the surface of the fillers, changing their surface properties, allowing them to better combine with paper fibers, significantly improving the compatibility between inorganic mineral fillers and organic polymer (paper fibers can be seen as organic polymers), enhancing the interfacial bonding strength. This enhances the mechanical strength and overall performance of the paper. For example, modified calcium carbonate fillers used in papermaking can significantly improve indicators such as the tensile strength and tear strength of the paper.
  2. Improving the dispersibility of fillers.: In the papermaking process, the dispersibility of fillers directly affects the quality uniformity of the paper. The powder surface modification machine can ensure that fillers are evenly dispersed in the paper, avoiding agglomeration. This is because the surface energy of the modified fillers is reduced, the viscous resistance between particles is decreased, and the flow performance is improved, similar to the fluidity of liquids, allowing for a more uniform distribution in the paper, making it smoother and more even. This also reduces wear on the paper machine.
  3. Reducing production costs.: On one hand, the powder surface modification machine can significantly increase the filling amount of powder fillers. Due to the improved performance of the modified fillers, the amount of fillers used can be increased while ensuring the quality of the paper, reducing the use of fibers and other expensive raw materials, thereby lowering production costs. On the other hand, the usage rate of the modifying agents is high and the amount used is small, which also reduces costs to some extent.
  4. Enhancing the special properties of paper.: According to different modification needs, the powder surface modification machine can endow paper fillers with some special physicochemical properties, thereby enhancing the special properties of the paper. For example, it can give the paper better oil absorption and printing suitability. Modified fillers can increase the adhesion of the paper to inks and colored pigments, making printed materials bright, vivid, and aesthetically pleasing. This meets the high requirements of the modern printing industry for paper.

2.Performance advantages of the powder surface modification machine.

  1. Continuous operation and large processing capacity.: It can operate continuously for production and has a large processing capacity, making it suitable for various scales of industrial papermaking production, meeting the needs of paper enterprises for large-scale production.
  2. High efficiency and energy saving.: The usage rate of modifying agents is high, the amount used is small, the powder coating rate and activation index are high, and energy consumption is low.
  3. Multifunctionality.: The equipment has functions ofdepolymerization, spheronization,and dispersion, making it suitable for materials of various fineness and achieving good modification and activation effects for different types of paper fillers.

Environmental protection and ease of operation.: The material operates under negative pressure, has good sealing, and dust does not leak, which basically does not cause pollution to the environment, while also improving the operating environment and reducing labor intensity.
