Manufacturing method of mine blow dryer

Abstract

The invention relates to a manufacturing method of a mine blow dryer, and the method comprises the following steps: manufacturing a foundation, namely weaving and expanding 1300D or 1500D ultralow contraction twisted polyster fiber filaments serving as warps and wefts by use of a braiding machine to form the gridded foundation; manufacturing a PVC (polyvinyl chloride) rolling film; and laminatinga film on the PVC rolling film and foundation, which are subjected to high temperature plasticizing, by a film laminator to obtain the mine blow dryer. The mine blow dryer manufactured by adopting the method provided by the invention has the advantages of good abrasive resistance and tear resistance, light weight, good water-proof, anti-fouling, mildew-proof, anti-flaming and anti-static effects and long service life, is ageing-resistant and can be formed singly.

Description

[0001] This patent application is a divisional application of the invention patent with the application number "200910101573.2", the application date is August 17, 2009, and the title is "A Coal Mine Air Duct and Its Manufacturing Method". technical field

[0002] The invention relates to a manufacturing method of a coal mine air duct, in particular to a manufacturing method of a coal mine underground single-formed high-strength flame-retardant and antistatic integral air duct. Background technique

[0003] At present, the overall air duct used in coal mines in my country is based on glass fiber fabric, which is processed by rubber calendering and treated with surface talcum powder. Existing air ducts for coal mines have low strength and are easy to blow open and leak air. They are not good in flame retardancy, antistatic, and soft. It needs to be spliced ​​and formed, the processing and manufacturing process is simple, and the warp and weft tearing strength is not up to sta...
