I. Core Performance: A classic choice for industrial and building insulation**
1. **Efficient insulation and stable temperature control**
-The thermal conductivity coefficient is as low as 0.032W/(m · K), which can effectively block heat conduction at room temperature (25 ℃). The insulation effect of a 10cm thickness is equivalent to the insulation performance of a traditional red brick wall of 1.2m, suitable for a wide temperature range of -268 ℃ to 600 ℃.
-Outstanding performance in high temperature scenarios: In working conditions such as power plant steam pipelines (350 ℃) and metallurgical furnaces, the surface temperature can be controlled below 50 ℃, reducing heat loss by 40% -60%.
2. **High strength anti vibration, structurally reliable**
-* * Compressive strength ≥ 0.08MPa * *, tensile strength ≥ 0.05MPa, able to withstand vibration and negative pressure impact during pipeline operation (such as negative pressure ≤ -5kPa in air conditioning systems), avoiding insulation layer detachment.
-Excellent flexural performance: No cracking after 1000 cycles of bending test, suitable for industrial pipelines that frequently start and stop (such as chemical reactor heat tracing pipelines).
3. **A-level fireproof, moisture-proof and corrosion-resistant**
-The non flammability meets the A-level standard, and it does not burn or melt when exposed to open flames. The smoke density during combustion is ≤ 5, and the toxicity index is 0. It complies with the highest level certification of GB8624-2012 "Classification of Combustion Performance of Building Materials and Products".
-The hydrophobicity rate is ≥ 98%, and the surface composite aluminum foil moisture-proof layer can isolate more than 95% of water vapor penetration. Its service life can reach 15-20 years in humid environments (such as underground pipe galleries and coastal areas).
4. **Green and environmentally friendly, circular utilization**
-Using natural basalt as the main raw material (accounting for ≥ 70%), the production process does not emit fluorine, and the waste can be crushed and melted for secondary utilization. It has obtained China Environmental Labeling Product Certification (Ten Ring Certification).
II. Diverse Scenarios: Full Scene Coverage in the Industrial and Architectural Fields**
