　　Introduction to 800mm mining positive pressure negative pressure flame retardant air duct:

　　It adopts a one-time heat sealing process with no longitudinal seams, and is a commonly used air duct in coal mines and tunnels. Its main features include anti-static, flame retardant, low air resistance, low air leakage, and high strength

　　Introduction to 800mm mining positive pressure negative pressure flame retardant air duct:

　　Made of seamless tube blank and carbon spiral spring steel wire, using advanced heat sealing technology. Negative pressure air ducts have the following characteristics: good suction effect, easy turning, convenient transportation and storage (foldable), long service life, etc

　　Variety and Material: The 600mm mining positive and negative pressure air duct has the characteristics of no air leakage per kilometer, beautiful appearance, wear resistance, corrosion resistance, and high adhesion strength between the inner ring pressure strip of the air duct spring and the coating cloth.

　　The quality of 800mm mining positive and negative pressure air ducts depends entirely on the materials used. Affordable positive and negative pressure air ducts are made of fiberglass cloth, while high-quality ones are made of coated cloth material, which is also used for explosion-proof water bags in coal mines. This material is sturdy and wear-resistant, mainly due to its high strength. This type of coated cloth positive negative pressure air duct is generally used in coal mines, iron mines, tunnel factories, and other places. According to different materials, positive and negative pressure air ducts are also divided into flame retardant and anti-static, non flame retardant and anti-static, flame retardant ones are expensive, and non flame retardant ones are moderately priced.

　　Technical specifications of 800mm mining positive pressure negative pressure flame retardant air duct:

　　Longitudinal tensile strength: ≥ 2500 N/50 mm, latitudinal tensile strength: ≥ 2000N/50 mm

　　Longitudinal and latitudinal tearing force: ≥ 190 N, adhesion strength:>22 N/25mm
