According to the cross-section of the air duct, the air duct can be divided into annular air duct, rectangular frame air duct, flat and circular air duct, etc., and it is complicated to make. Therefore, the rectangular air duct is used to dominate. According to the material, the air duct can be divided into metal material duct, composite duct and polymer material duct. Galvanized air duct is the end of the flange groove inserted into the hose board and glued together with the adhesive. If nothing is left, there will be a gap between the slot and the end of the hose so that they cannot stick together. 1. When the gas galvanized air duct is installed on the road surface with its own fittings, because of the bending of the self-acting force, the length of its own fittings is relatively limited, so as to avoid the damage of the gas galvanized air duct. 2, shaft vertical natural ventilation galvanized air duct installation, because the indoor space is small, is not conducive to maintenance, so the Angle iron flange duct is generally selected to enhance the horizontal and compressive strength of the advantages of coat connection, and make the flange "um" way, steel clothes rack hanging on the ear Angle iron flange immediately does not set the applicable. 3. Installation and installation of glass fiber polymer material board with non-flange connection installed vertically. 4. The joint between the tenon and the air duct is connected to the tenon, and the adhesive is used to improve the compressive strength of the receiver. 5. The galvanized air duct for natural ventilation should avoid being damaged in the whole process of transportation. 6. When the terminal number of the galvanized air duct of the glass fiber sandwich board is laser cutting surface, the use of adhesive tape or strong glue sealing, to avoid the exposure and dispersion of the glass fiber before installing the flange connector.
