    Technical Parameters

    Working Principles

    The asphalt-based pre-oxidation furnace mainly uses high temperature and oxidizing atmosphere to cause an oxidation reaction of the asphalt-based carbon fiber precursor, realize the cyclization and cross-linking of the macromolecular chain, and convert it into a non-plastic heat-resistant trapezoidal structure, so that it will not melt or burn under the subsequent carbonization high temperature, and maintain the fiber morphology.

    Frequently Asked Questions

    Q: What is the primary function of the asphalt-based pre-oxidation furnace?

    It uses high temperatures and an oxidizing atmosphere to trigger an oxidation reaction in the asphalt-based carbon fiber precursor.

    Q: What molecular changes occur during the pre-oxidation process?

    The process facilitates the cyclization and cross-linking of the macromolecular chain within the precursor material.

    Q: What type of structure is the precursor converted into?

    The precursor is transformed into a non-plastic, heat-resistant trapezoidal structure.

    Q: Why is the creation of a heat-resistant trapezoidal structure necessary?

    This structure ensures that the material does not melt or burn during the subsequent high-temperature carbonization phase.

    Q: How does the pre-oxidation furnace help maintain fiber morphology?

    By converting the fiber precursor into a non-plastic and thermally stable structure, it preserves the physical shape of the fiber throughout subsequent thermal processing.
