Insulating paper machine is to make insulating paper with specific properties and specifications by making paper raw materials through a series of processes.It has good electrical insulation properties, high temperature resistance, etc., used in transformers, motors, generators and other electrical equipment.

Production process and technology of insulation paper

The production process of insulation paper is a complex and delicate process, involving multiple links and technologies. Firstly, the selection of raw materials is crucial for producing high-quality insulation paper. Traditional insulation paper mainly uses wood pulp as raw material, while modern insulation paper uses more polymer materials such as polyester and polyimide. These materials not only have excellent electrical properties, but also maintain stability in high temperature and high voltage environments.

In the raw material preparation stage, wood pulp or polymer materials need to undergo a series of processing steps, such as pulping, bleaching, and drying. Beating is the process of breaking down raw materials into fibers for subsequent processing. Bleach is used to remove impurities from raw materials, making them purer. Drying is to remove moisture from raw materials, improve their mechanical strength and electrical performance.

The next step is the preparation process of pulp. Pulp is a suspension composed of fibers and water, which is processed into thin sheets through a series of filtration and pressing techniques. This process requires strict control of temperature, humidity, and pressure to ensure the uniformity and stability of the pulp.

After the pulp preparation is completed, it enters the coating and rolling process. Coating is the process of applying a thin layer of resin or other chemical substance onto the surface of pulp to enhance its heat resistance and electrical properties. Rolling is the process of compressing pulp into the desired thickness and density through high temperature and high pressure. This process requires precise equipment and strict process control to ensure the quality of the insulation paper.

Finally, there is the cutting and packaging of insulation paper. Cutting is the process of cutting large rolls of insulating paper into the desired size and shape for subsequent use. Packaging is used to protect the safety of insulation paper during transportation and storage, usually using moisture-proof and dust-proof packaging materials.

Overall, the production process of insulation paper involves multiple stages and technologies, each of which requires strict control and precise equipment. Through continuous technological innovation and process improvement, the quality and performance of insulation paper have been significantly improved, providing a solid guarantee for the development of the electrical insulation field.

What are the steps involved in the production process of insulation paper

The production process of insulation paper usually includes the following steps:

1. Raw material preparation: Select suitable natural fiber materials such as wood pulp or bamboo pulp, and sometimes use chemical fibers such as glass fiber or synthetic fiber as reinforcement materials.
2. Beating: The raw materials are processed into a uniform slurry by a pulping machine.
3. Screening and Purification: Through the screening and purification process, impurities and uneven substances in the slurry are removed to ensure the quality of the slurry.
4. Slurry adjustment: Add various chemical additives such as adhesives, fillers, lubricants, etc. as needed to improve the performance of insulation paper.
5. Molding: Apply the blended slurry evenly onto a mesh or cloth substrate, and shape it into thin sheets through processes such as pressing and drying.
6. Drying: Remove moisture from paper using hot air, hot plates, or other drying methods to achieve a certain degree of dryness.
7. Polishing: The dried paper is treated with a calender to improve its surface smoothness and uniformity.
8. Cutting: Cut the paper into different shapes and sizes according to the required size.
9. Testing and classification: Conduct quality testing on the produced insulation paper, including thickness, density, electrical strength, heat resistance, and other indicators, and classify it according to standards.
10. Packaging: Pack the qualified insulation paper for transportation and sale.

The entire production process requires strict control of conditions such as temperature, humidity, pH value, etc. to ensure that the quality and performance of the insulation paper meet the standard requirements. With the development of technology, the production process of insulation paper is constantly improving to meet the ever-changing market demand.
