Product Description
膨張黒鉛
膨張黒鉛は、加熱すると膨張または剥離する黒鉛の合成インターカレーション化合物です。加熱すると、体積が最大400倍に増加し、かさ密度が低下し、表面積が約10倍に増加します。その後、高度に凝集した柔軟なシートに圧縮されます。
もう一つの主な用途は、難燃剤としての使用です。火災の熱により黒鉛が膨張し、材料の表面に膨張性層が生成されます。これにより、火災の拡大が抑制され、燃焼の最も有害な影響の1つである有毒ガスや煙の発生が最小限に抑えられます。
難燃剤としての膨張黒鉛の利点:
- 熱放射シールドを備えた膨張性層を形成し、優れた熱拡散性を実現。
- 火災と有毒ガスの拡散を阻止または遅延。
- 塗布が容易で、費用対効果が高く、添加量が少なくても性能が満足。
- 無毒で、ハロゲンを含まない防火添加剤。
- 中性の表面pHにより、あらゆる触媒システムと互換性があります。
