    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.

    Oxidation Reaction

    Utilizes controlled high temperature and an oxidizing atmosphere specifically designed for asphalt-based carbon fiber precursor processing.

    Macromolecular Linking

    Realizes the critical cyclization and cross-linking process within the macromolecular chain structure.

    Thermal Stability

    Converts the material into a non-plastic, heat-resistant trapezoidal structure to prevent melting during carbonization.

    Frequently Asked Questions

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

    Its primary purpose is to trigger an oxidation reaction in the asphalt-based carbon fiber precursor, preparing it to withstand subsequent high-temperature carbonization processes.

    Q: What conditions does the furnace use to cause the oxidation reaction?

    The furnace achieves the oxidation reaction by utilizing a combination of high temperature and a controlled oxidizing atmosphere.

    Q: What happens to the macromolecular chain during this process?

    The pre-oxidation process successfully realizes both the cyclization and cross-linking of the precursor's macromolecular chain.

    Q: What is the benefit of converting the precursor into a trapezoidal structure?

    Converting it into a non-plastic, heat-resistant trapezoidal structure ensures that the material will not melt or burn when subjected to higher carbonization temperatures.

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

    By forming a heat-resistant trapezoidal structure, the fiber is stabilized chemically, allowing it to maintain its physical shape and morphology throughout the subsequent carbonization stage.
