Light plastic-woven inner sticking film air duct

Abstract

The invention discloses a light plastic-woven inner sticking film air duct which comprises a polyethylene plastic mesh braiding layer (1) as a framework and an inner leakage preventing layer (2) bonded with the outer polyethylene plastic mesh braiding layer (1) to from a whole, wherein the inner leakage preventing layer (2) is a dual-layer co-extrusion blown film with the thickness of 0.005-0.04mm and is formed by selecting materials, braiding, hot melting and internally sticking. The light plastic-woven inner sticking film air duct disclosed by the invention has the beneficial effects that local quality and ventilation resistance of the air duct are reduced; ventilation energy consumption is reduced and energy sources are reasonably and fully utilized; and meanwhile, the handling difficulty is reduced and the operation efficiency is increased. Compared with a traditional air duct, the light plastic-woven inner sticking film air duct has the advantages that the cost of a fabric for local fan ventilation is reduced; the weight is light; the labor intensity during mounting is reduced; and repeated use and reproductivity are realized.

Description

technical field [0001] The invention relates to a lightweight plastic braided inner mucous membrane air cylinder, which belongs to the field of ventilation safety. Background technique [0002] Ventilation is an essential means for underground mine mining, dusty environment management on the ground, and ensuring the health of workers. As far as local ventilation is concerned, it is generally completed by connecting a fan to a section of air duct. At present, domestic mine partial fan ventilation mainly uses high-strength polymer Resin glass fiber is woven into a coated base fabric, and PVC, PE, and EVA are modified as a surface film and compounded. The production process is more complicated, the risk is high, and the price is high; the quality of the air duct is large, and the ventilation energy consumption is high; It is inconvenient to transport and requires the cooperation of equipment. The suspension and maintenance need to be completed by multiple people, and the labor ...
