3. -40°C to 120°C operational range.
Product Introduction:
Haoyang Environmental's innovative prefabricated bentonite panels revolutionize containment system installation with their modular 1m×2m sections featuring advanced peel-and-stick seam technology. These factory-assembled units incorporate a high-swelling sodium bentonite core (≥24mL/2g) bonded between reinforced polypropylene geotextiles, enabling rapid deployment at rates exceeding 300m²/hour - ideal for emergency spill containment, flood protection barriers, and time-sensitive remediation projects. The pre-applied pressure-sensitive adhesive strips eliminate traditional seaming requirements while maintaining ≤5×10⁻¹¹ m/s permeability, with field validation showing 98% seam integrity even under 50kPa shear stress.
Product Applications:
1. Landfill liners - Prevent leachate contamination using high-density geomembranes with excellent chemical resistance.
2. Road construction - Reinforce weak subgrades and separate soil layers with durable woven geotextiles.
3. Erosion control - Stabilize slopes using permeable geotextiles that allow vegetation growth.
