[Outline]
The development points of the high-grade copperplate paper coating preparation system include: key technologies for localization of coating raw materials, key technologies for automatic control of coating preparation systems, and industrialization technologies for coating preparation systems. The key technologies for localization of coating materials are mainly white dyes (including kaolin, calcium carbonate, satin white, barium sulfate, etc.), adhesives (including latex, starch, casein, polyvinyl alcohol, etc.), small amounts of additives, and water. Four parts. After research and development, small-scale trials, pilot tests and more than one year of operation on paper machines, the localization rate of raw materials has reached 92%. The key technology of automatic control of the paint preparation system realizes continuous, automatic, and interlocking additions to ensure consistent and consistent coating quality. The bulk materials are measured using an electronic weight sensor and the small items are measured volumetrically. Based on the development of the above two key technologies, the process of industrializing the paint preparation system has been accelerated. Through the optimization and screening of domestically produced raw materials, different formulations for one coat, two coats and three coats were determined, the process flow and equipment configuration were optimized, and a complete coating preparation system was formed, thus ensuring the satisfaction of production. High-quality coating for coating operations. 
