Applications & Industries
Power Plants and Utilities
Safe handling of coal and other flammable powdery materials in exposed environments.
Chemical Industries
Eliminates ignition risk when conveying corrosive and potentially explosive chemicals.
Coal Mining (Above Ground)
Used in surface preparation plants where $\text{GB/T}$ fire-resistance certification is mandated.
General Hazardous Areas
A highly reliable solution for any industrial site with flammable or explosive atmosphere.
As a specialized custom solution provider, Hebei Boao views these figures as performance benchmarks. We provide precision engineering, meaning the following parameters are fully negotiable and will be fine-tuned to your exact project needs: Belt Width, Cover Thickness, Carcass Fabric Type (EP or NN), Rubber Grade (H,D or L), and the required Fire Resistant Grade (K1，K2 or K3). Our final product is certified to meet your unique specifications, ensuring optimized performance and longevity.

FAQs
1. What does the K grade certification mean for fire safety?
The K grade refers to the strict flame resistant classification under the Chinese national standard GB/T 10822-2014, indicating the belt's performance in preventing flame spread.
2. What is the difference between H,D, and L cover property grades?
These grades denote the physical strength and abrasion resistance of the cover rubber. H is the highest grade for tensile strength (24.0 MPa) and D offers the lowest abrasion loss (100 mm³).
3. How is the anti-static property guaranteed?
The belt is formulated with conductive materials to ensure the static conductive property remains at or below 3×10⁸ Ohms across all K grades.
4. Is this belt suitable for use in areas with high explosives?
Yes, its anti-static and non-flame reappearance properties make it suitable for flammable and explosive environments on the ground.
5. Can the cover grade and fire grade be combined?
Yes, we customize the belt by
combining the required abrasion resistance (H/D/L) with the mandated fire resistance
level (K1/K2/K3) for optimal performance.
6. What type of fabric core is used for this belt?
We typically use EP (Polyester/Nylon)
fabric cores due to their low stretch and stability, ensuring thebelt maintains excellent
tracking and dimensional integrity.
7. Is there any risk of flame reappearance after the test?
No, the GB/T standard
explicitly requires that the reappearance of flame is not allowed in any sample tested,
guaranteeing maximum safety.
