ポリエチレン（PE）道路マット used in underground coal mines are engineered ground covering materials designed for harsh and hazardous mining environments. These mats are made primarily from high-density polyethylene (HDPE) combined with specific additives, offering a range of properties ideal for industrial use.
PE Material Characteristics:
PE sheets exhibit excellent resistance to both heat and cold, with performance maintained even at -100°C. HDPE in particular offers outstanding electrical properties, especially high dielectric strength, making it highly suitable for use in electrical insulation such as wire and cable applications. Medium to high molecular weight grades have exceptional impact resistance.
The unique performance of HDPE arises from the optimized combination of four basic variables: density, molecular weight, molecular weight distribution, and additives. Different catalysts are used to tailor the polymer for specific performance requirements, resulting in various HDPE grades that provide a well-balanced performance profile. HDPE also has excellent chemical stability, showing resistance to most acids, alkalis, organic solvents, and hot water. Additionally, it provides excellent electrical insulation.
Flame-Retardant, Anti-Static PE Road Mats for Coal Mines
These road mats are specially designed for use in coal mine environments, where fire resistance, anti-static properties, corrosion resistance, and wear resistance are essential. They are primarily composed of polymer materials and functional fillers, ensuring safety and durability in mining operations.
主な機能:
- Flame Retardant: Special chemical formulations and processing methods allow the mats to meet Class A non-combustible material standards, significantly reducing fire hazards.
- Anti-Static: Conductive fillers are added during production to effectively dissipate static electricity, enhancing operational safety.
- Corrosion Resistant: The use of high-performance polymer materials ensures stability even in highly acidic or alkaline environments.
- Wear Resistant: Surface treatment technology increases surface hardness and abrasion resistance, extending the service life.
- Easy to Clean: The smooth and flat surface prevents the buildup of contaminants, making cleaning and maintenance simple.
Thanks to these advantages, polyethylene road mats are widely used in the coal industry, particularly in areas such as underground tunnels, locomotive depots, stockpiles, and loading zones.
