Product Properties:
1. Fire proofing:withstand at least 1000ºC high temperature without melting, conforming to GB8624-2012 A1 class.
2. Thermal insulation:thermal conductivity coefficient is 0.032-0.040 for rockwool panel and under 0.045 for rockwool belt.
3. Weather resistance:acidity coefficient above 2.0, non-corrosive to all kinds of material.
4. Hydrophobicity:hydrophobicity above 99%, preventing moisture absorption effectively.
5. High strength:high compressive and tensile strength at the same density.
Production Process:
Use natural rock as raw material→ At a constant temperature of 1500ºC ,with remarkable fire resistance performance; Sustainable,stable and high-efficient produce; low carbon and environment-friendly, without solid waste and smoke discharge→ Well- distributed wool;Capable of extra-width produce→ Three-dimension crimping process; with high compressive and tensile strength→ With accurate dimension; Achieve clean produce.→ Multi-point on-line monitoring; ensure stable quality.
