Description
The overall core flame-retardant conveyor belt (PVC-PVG) is mainly used in underground coal mines. Features of this belt: the belt body does not delaminate, small elongation, impact resistance, and tear resistance.
(1) PVC flame-retardant conveyor belts are suitable for material conveying under dry conditions with an inclination angle of less than 16 degrees.
(2) PVG flame-retardant conveyor belts are suitable for conveying wet materials with an inclination angle of less than 20 degrees.
1. Model N/mm (tensile strength):
| Level | Level 4 | Level 5 | Level 6 | Level 7 | Level 8 | Level 9 | Level 10 |
| Model | 680s | 800s | 1000s | 1250s | 1400s | 1600s | 1800s |
2. Flame-retardant performance:
(1) Roller abrasion number: The surface temperature of the roller is not more than 325℃.
(2) Blowtorch burning: The average flameless time of the full-thickness specimen without a blowtorch is not more than 3.0S, and the average flameless time without the covering layer is not more than 5.0S.
(3) Propane burning: The undamaged length is greater than 250mm
3. Surface resistance value:
The average value of the upper and lower surfaces is not more than 3.0 × 108Ω
4. Performance:
This conveyor belt has passed flame-retardant tests and electrostatic tests and has obtained a qualified certificate, coal mine safety mark, and customer recognition.
5. Mechanical properties:
Excellent mechanical properties can provide users with a longer service life and economical installation and use.
Service life: The service life of the belt is determined by the following factors: the warp and weft filaments are woven into a dense belt core; the specially formulated PVC material makes the belt core and cover rubber achieve high bonding strength; specially formulated cover rubber; thus making the belt body impact-resistant, tear-resistant, and wear-resistant.
This product has excellent performance such as wear resistance, anti-static, waterproof, flame retardancy, and high strength of the whole-core flame-retardant belt, and is lower in cost and price compared to other flame-retardant conveyor belts. It is one of the more common and popular flame-retardant conveyor belt varieties at home and abroad, especially suitable for conveying places with small slopes such as underground coal mines.
6. Product structure:
This product uses a whole-core as the skeleton material, which is made by impregnation and coating with PVC materials with anti-static and flame-retardant properties.
7. Joint performance:
According to the belt strength and core structure, mechanical buckle connection is used, and its strength can reach 50%-100% of the belt strength; vulcanized joints are used, and their strength can reach 60%-100% of the belt strength. Various types of joints can meet the different needs of customers and ensure the safe and efficient operation of the system.
