Flame retardant and anti-static air door and mining electric control pneumatic automatic device

The PVC polymer composite material air door for mining is a flame-retardant and anti-static air door that can be safely used underground in coal mines. Common fireproof board material specifications include 40x300, 35x250, etc; It combines with remote intelligent automatic electronic pneumatic devices (systems) to become a relatively complete and advanced ventilation equipment.

Compared with iron non pressure air doors or forward and backward doors, the production cost of flame-retardant and anti-static air doors for mining is relatively high. However, there are also anti-static properties that steel balance air doors do not have. Iron non pressure regulating air doors or ordinary two-way doors are generally designed with square steel door frame welded with Q235 steel plate on the outside. Mining polymer composite air doors generally have iron material as the outer skeleton of the door leaf, and polyvinyl chloride fireproof door panels are embedded in grooves and fixed with high-strength screws. During use, if the door leaf of a coal mine electric controlled pneumatic automatic flame-retardant and anti-static air door is damaged by collision, the screws can be loosened to replace the old damaged door panel with a new polymer composite fireproof door panel, which does not affect the normal use in the later stage. This is what iron balance air doors are used for. Not available.

Mining flame-retardant and anti-static air doors have high strength and wear resistance, can withstand complex conditions and frequent use in mining environments, and have excellent chemical corrosion resistance. They can resist the erosion of various common chemical substances in mines, which is beneficial for extending the service life of ventilation equipment and reducing production and operation costs.
