Problems solved by technology
Iron sheet air ducts have a short service life in humid and corrosive medium environments, and need regular maintenance and replacement; rubber cloth air ducts are made of thermoplastic composite materials composed of rubber, cotton threads or steel wires, and their impact resistance is poor. When in use, the wind resistance is large, the ventilation rate is relatively low, and the cylinder body is easy to expand and deform, which makes the ventilation unstable; the cylinder body is made of glass fiber reinforced plastic, and the flange is made of steel. It is made into a glass fiber reinforced plastic barrel, and then the steel flange is made, and then the steel flange is fixed on the glass fiber reinforced plastic barrel. Another disadvantage of this kind of air duct is that the weight is relatively increased, and the steel flange is still easy to use during use. Corrosion phenomenon, bring safety hazard

Embodiment Construction
[0012] One-piece plexiglass steel air duct, including the cylinder body and the flange, the flange and the cylinder body are of an integrated structure, and the material is glass fiber reinforced plastic. The production is completed by the following steps:
[0013] (1) Making a flat plate: Cut the glass fiber cloth into the size of the tube body, spread the bottom glass fiber cloth on the plastic paper first, and coat the surface of the glass fiber cloth with resin, so that the glass fiber cloth is covered layer by layer to make Thickness is required, a flat plate is formed after curing, and the plate is peeled off;
[0014] (2) Make the flat plate into a cylinder body: After cutting the flat plate according to the area requirements, roll it into a cylinder, use glass fiber cloth as a seal, coat the seal with resin, and seal it. After the seal is cured, it will become a cylinder body. ;The size and length of the seal is cut according to the size and length of the seal, the len...

The manufacturing method of the one-piece plexiglass steel air duct relates to the organic glass steel air duct used in underground mines. The flange and the cylinder body are of an integrated structure, both of which are made of glass fiber reinforced plastics. The outer surface of the body is made, and the steps of drilling the flange side of the fan after curing are completed. It has the advantages of light weight, high strength, corrosion resistance, long service life, simple maintenance, flame retardant and antistatic, easy installation, and not easy to leak air. Its weight Lightweight, good ventilation performance, especially suitable for underground use in mine engineering with large air volume, humid, acidic and gasy medium environments.
Description
technical field [0001] The invention relates to an organic glass steel air duct used in underground mines, in particular to an integrated organic glass steel air duct, and provides a manufacturing method of the air duct. Background technique [0002] The ventilation ducts used in underground mines are usually composed of a cylinder body and a flange. There are iron ducts, rubber cloth ducts, and ducts whose body is made of glass fiber reinforced plastic and the flange is made of steel. Iron sheet air ducts have a short service life in humid and corrosive medium environments, and need regular maintenance and replacement; rubber cloth air ducts are made of thermoplastic composite materials composed of rubber, cotton threads or steel wires, and their impact resistance is poor. When in use, the wind resistance is large, the ventilation rate is relatively low, and the cylinder body is easy to expand and deform, which makes the ventilation unstable; the cylinder body is made of gl...
