Embodiment Construction

[0010] The production and installation process of phenolic aluminum foil composite air duct, the process steps are:

[0011] In the early stage, the engineering drawings were drawn according to the construction site, and the engineering drawings were disassembled to determine the installation positions of the air-conditioning equipment and air duct components. The quantity of air duct specifications, that is, the reasonable length and quantity of straight air ducts and special-shaped ducts, is measured and marked on the plate, and rectangular straight air ducts and T-shaped rectangular air ducts are staked out. Measure with a steel ruler, use a paintbrush and square aluminum Draw the cut-off line, V-shaped groove line, and 45-degree slope line with the alloy ruler, make the lofting of rectangular bend pipe, rectangular reducer pipe and rectangular bifurcated pipe, and draw the cut-off line, 45-degree slope line, and bending line Or V-shaped groove line, move the knife along th...

Abstract

The invention provides a manufacturing and mounting process for composite phenolic aldehyde aluminum foil air pipes. The process comprises the steps of decomposition of an engineering drawing, and setting of the specification and the number of the air pipes; measuring and scribing of plates, blanking through a cutter, and gluing of notches of the plates; splicing of the air pipes, pasting of aluminum foil adhesive tape on the splicing joints of the air pipes, gluing of the pipe openings of the air pipes, and mounting of zinc-iron compensation corners on the pipe openings; blanking and gluing of flanges, mounting of the flanges on the pipe openings of the air pipes, and coating of sealants at the splicing joints; adding of a fixing support to one large air pipe, and inserting in the positions, connected with the flanges, of the air pipes; and blanking and manufacturing of a cross beam before hoisting of the air pipes, mounting of suspenders and the cross beam, and hoisting of the air pipes. According to the manufacturing and mounting process for the composite phenolic aldehyde aluminum foil air pipes, the phenolic aldehyde air pipes and aluminum foil are composited, the pipe openings and the notches are subjected to gluing and aluminum foil adhesive tape pasting, the manufacturing process is exquisite, and the manufacturing and mounting speed is high.

Description

technical field [0001] The invention relates to a production and installation process of a composite air duct, in particular to a production and installation process of a phenolic aluminum foil composite air duct. Background technique [0002] At present, domestic ventilation and air conditioning pipes are mainly made of galvanized steel sheets, and the pipes are sometimes covered with insulation layers such as glass wool, polyethylene foam or rubber sponge. This kind of traditional air duct has long installation period, high production cost, heavy weight, poor heat insulation performance and poor appearance, which makes the users and designers of central air conditioners eagerly hope for the emergence of new air duct materials. [0003] The application of phenolic composite air ducts is relatively concentrated in the fields of large-scale commercial buildings, public buildings, and industrial buildings. Phenolic foam board and aluminum foil are composited into a sandwich p...
