The application of coating modifier in papermaking filler is an important direction of technological innovation in papermaking industry in recent years. By coating modification, the surface properties of the filler can be improved, and its retention rate and distribution uniformity in the paper can be improved, thereby enhancing the performance of the paper and reducing the production cost. The following is the specific application and advantages of the coating modification machine in papermaking filler:

Purpose and Advantages of 1. Coating Modification Technology

1. Increase filler retention rate:Both the pulp fibers and the filler particles have a negative charge on the surface, making it difficult for the filler to be effectively retained in the paper sheet during the papermaking process. By coating modification, the filler can be given a positive charge or improve its surface characteristics, thereby increasing the binding force between the filler and the pulp fiber and improving the retention base of the filler..

2. Improve paper performance:The uniform distribution of fillers in the paper helps to improve the optical properties of the paper such as smoothness, opacity, whiteness and gloss. At the same time, the appropriate coating modification can also reduce the negative impact of the filler on the strength performance of the paper and even improve the physical strength of the paper.

3. Reduce production costs:By increasing the amount of filler and reducing the amount of fiber, the cost of raw materials in the papermaking process can be reduced. In addition, the coating modification may also improve the dewatering and drying properties of the pulp, thereby reducing energy consumption.

2The development trend of coating modification technology With the continuous improvement of product quality and environmental protection requirements in the paper industry, coating modification technology will be further developed in the following aspects:

1. Green:Develop environmentally friendly coating materials and modification methods to reduce environmental pollution.

2. Efficiency:Improve the efficiency and effect of coating modification and reduce production costs..

3. Functionalization:The special functionality of the fuzi filler, such as antibacterial, fireproof, oil proof, etc., to meet the market demand for functional paper.

In summary, the application of coating modification machine in papermaking filler is of great significance, which can not only improve the performance of paper and reduce costs, but also promote the sustainable development of the paper industry.
