Mining polymer composite material air door

underground coal mineMining polymer composite material air doorThe door leaf is generally made of iron keel, and the door leaf panel is processed and made of polyvinyl chloride fireproof board. The coal mine polymer composite material balanced air door (pneumatic positive and negative non pressure air door) has anti-static, flame retardant and high compressive strength.

Mining polymer composite material air doorMainly used in each connecting lane between the intake and return lanes and the main intake and return air lanes, conventional iron non pressure dampers have their drawbacks, such as rusting and deformation over time, leading to stable descent of positive and negative balance dampers, and sparks generated by friction between irons, causing major safety hazards; Polyvinyl chloride polymer pressure free air door eliminates this contradiction.

underground coal mineMining polymer composite material air doorLightweight, fire-resistant, and moisture-proof. Due to the fact that the PVC non pressure balanced air door is made of spliced materials and comes with its own color at the factory, production is also relatively fast and has good environmental performance. In addition, the coal mine polymer composite material air door is beautiful, generous, and durable. Its material properties are stable and reliable, reducing the frequency of air door maintenance and greatly improving the operational efficiency of the mine.
