Polymer composite material air door

Mining grade polyvinyl chloridePolymer composite material air doorIt is a ventilation equipment used in underground mines such as coal mines and iron mines. It is mainly used for isolating air flow, remote fully automatic intelligent control ventilation, and polymer composite fireproof board with flame retardant and anti-static properties. It can effectively prevent fires and static electricity accumulation, reduce explosion risks, and meet the safety requirements of coal mines.

coal minePolymer composite material air door(Non pressure balance damper) Corrosion resistance and aging resistance: it can resist underground moisture, acid and alkali and other corrosive media, with good aging resistance and extended service life; High strength, able to withstand certain pressure, and lightweight, easy to handle, install, and disassemble.

polyvinyl chloridePolymer composite material air doorThe door leaf is usually framed with iron keel, and the polymer composite fireproof board is sandwiched in the middle with a U-shaped groove. If one of the pieces is damaged, it can be disassembled and replaced with a new PVC board for continued use. This feature is not available for iron positive and negative air doors or balance doors. Compared to traditional steel or wooden balanced non pressure dampers, it has the advantages of corrosion resistance and long service life, reducing maintenance and replacement work and lowering costs.
