Problems solved by technology

Therefore, now most of the process of spraying powder first and then threading is used. However, the method steps adopted by various domestic processes are difficult to effectively guarantee the quality of the final product. Therefore, an excellent process of spraying first and then threading of aluminum profiles is now provided.

Embodiment Construction

[0025] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0026] An aluminum profile is first sprayed and then threaded. The process steps are as follows:

[0027] a. cutting: cutting the unsprayed aluminum alloy raw materials according to the proportion to form aluminum profiles;

[0028] b. Aluminum profile surface cleaning treatment: After grinding the aluminum alloy surface and rinsing with water; put in the mixed acid solution for 5-7 minutes, take it out and rinse with water;

[0029] c. Passivation treatment: After rinsing the aluminum alloy with pure water, place the aluminum alloy in the passivation solution. After 6-12 minutes, a colored passivation film is formed on the surface of the aluminum alloy;

[0030] d. Drying: place the passivated aluminum profile in a drying oven to dry;

[0031] e. Electrostatic spraying: put the punch mold in the aluminum profile, and then send it into the electrostatic spraying mac...

Abstract

An aluminum profile first-spraying and last-assembling process comprises the following process steps of a, cutting; b, cleaning of the surfaces of aluminum profiles; c, passivation treatment; d, drying; e, electrostatic spraying; f, paint-drying; g, punching; and h, assembling. The first profile and the second profile are regular in section shape and good in symmetry, and can be very tightly connected after being pressed tightly. According to the door and window aluminum profile surface powder electrostatic spraying method, the aluminum alloy profiles without spraying are cut and then subjected to powder electrostatic spraying, paint-drying, cooling and punching, color fading is avoided when the door and window aluminum profiles are punched, and colors are beautiful; and meanwhile, the strength of the door and window aluminum profiles can be improved, the production process procedures can be decreased, and the equipment cost is lowered.

Description

technical field [0001] The invention relates to an aluminum profile processing technology, in particular to a process of spraying and then threading an aluminum profile. Background technique [0002] In the prior art, most of the strip-type powder-sprayed heat-insulation profiles produced in the European Union are the process of threading the strips first and then spraying powder, using heat-insulation strips with hot-melt adhesive lines. Most of the strip-type heat-insulation profiles produced in China are sprayed with powder first and then threaded. The heat-insulation strips without hot-melt glue lines are used. Composite processing of heat-insulating profiles with ordinary heat-insulating strips without hot-melt adhesive lines can obtain high shear resistance as long as the process is proper. However, if the surface is to be powder-coated, after drying and curing processes , under the effect of high temperature, the outer chuck of the notch of the aluminum profile heat ...
