Benefits
1. The length of PAN fiber is neat and standard, with excellent dispersion and processability.
2. The single PAN fiber has fine fineness, high strength, and a large number of fibers added with the same weight. The mesh structure is more stable, significantly reducing plate cracking, chipping, and powder removal.
3. Good temperature resistance, suitable for the high temperature at the instant of adding acid to the paste and the high temperature requirements during the drying process, without softening and deformation.
4. Good acid resistance, chemical and electrochemical corrosion resistance, anti-aging, normal scrapped battery plate. After anatomical inspection, the PAN fiber is basically unchanged.
