Graphite paper is a material made of high-carbon phosphorus flake graphite through special processing and high-temperature expansion rolling. Because of its good high-temperature resistance, thermal conductivity, flexibility, and lightness, it is widely used in the manufacture of various graphite seals, thermal conductive elements of micro devices, and other fields.
1. Raw material preparation
- Select high-quality high-carbon phosphorus flake graphite as raw material, check its composition ratio, impurity content and other quality indicators,
According to the production plan, pick up the raw materials and stack them in categories to ensure that they are consistent with the production plan requirements.
2. Chemical treatment
- Chemical treatment of the raw materials to convert them into worm-like graphite that is easy to process.
3. High-temperature expansion
- Put the treated raw materials into a high-temperature expansion furnace to fully expand them into graphite paper.
4. Spreading
- Pre-pressing and precision pressing are automated through manual operation with keyboard, and finally qualified graphite paper products are produced on the paper roll.
5.Quality inspection
- Quality inspection of graphite paper to ensure that the product meets various performance indicators.
Packaging and storage
Packaging qualified graphite paper and stacking it neatly in the warehouse
The above is the production process of graphite paper. Strict control of each link directly affects the performance and quality of the final product.
