​Alkali Resistant Basalt Fiber Yarn Environmental Protection For Military Applications​

​​​​Basalt Fiber Civil Engineering Transportation Infrastructure Environmental Protection And Military Applications​​

​​1. Product Introduction​​

Basalt Fiber Material is an advanced inorganic composite derived from natural volcanic basalt rock. Melted at 1,450–1,500°C and drawn into continuous filaments, it offers exceptional mechanical strength, thermal stability, and corrosion resistance. Key features:

• ​​Eco-Friendly​​: 100% natural, recyclable, and free of carcinogens

  .

• ​​Extreme Temperature Tolerance​​: Operates in -269°C to 800°C environments

  .

• ​​Chemical Resistance​​: Impervious to acids, alkalis, and solvents

  .

• ​​Lightweight​​: 20–30% lighter than fiberglass with equivalent strength

  .

• ​​Applications​​: Structural reinforcement, thermal insulation, automotive parts, aerospace components, and fireproof textiles

  .

​​2. Manufacturing Process​​

1. ​​Raw Material Processing​​:

   • Basalt rock is crushed and melted in a platinum-rhodium alloy furnace at 1,450–1,500°C

     .

2. ​​Fiber Drawing​​:

   • Molten basalt is extruded through spinnerets to form 7–25 µm diameter filaments

     .

3. ​​Textile Production​​:

   • Filaments are woven into unidirectional (UD), plain, twill, or satin fabrics using precision looms

     .

4. ​​Surface Treatment​​:

   • Coated with sizing agents (e.g., silane) to enhance adhesion and UV resistance

     .

5. ​​Quality Control​​:

   • ISO 9001-certified testing for tensile strength (3,800–4,800 MPa) and thermal stability

     .

​​3. Usage Precautions​​

• ​​Mechanical Handling​​:

  • Avoid sharp tools or excessive bending to prevent fiber breakage

    .

• ​​Chemical Exposure​​:

  • Resistant to most chemicals but avoid prolonged contact with strong oxidizers (e.g., concentrated sulfuric acid)

    .

• ​​Thermal Management​​:

  • Prevent rapid temperature shifts to avoid thermal shock cracking; use in dry conditions

    .

• ​​Storage​​:

  • Store in ventilated, dry areas; avoid folding under tension

    .
