Abstract
The invention discloses a spraying method of an aluminum alloy door/window section. The spraying method includes adopting a chromaking method to form a chromium film 800 mg/m2-1000 mg/m2 in thickness on the surface of the aluminum alloy section; subjecting the aluminum alloy section preprocessed to drying at 50-60 DEG C; coating the surface of the aluminum alloy section with powder coating through a powder spray gun to form the organic polymer membrane with protection and decoration functions, to be specific, spraying voltage is 70 KV, and spraying distance is 250-280 mm, and then performing solidification to the aluminum alloy section to form a coating. The spraying method is simple, the coating is uniform and firm, and protection function is achieved.
Description
Technical field
The invention belongs to aluminium section bar processing technology field, be specifically related to the spraying process for treating of a kind of aluminium alloy door window profile.
Background technology
Aluminum alloy building section is the main structural material of current door and window and curtain wall, extensive use in worldwide.Not surface treated aluminum alloy extrusion section bar outward appearance is single, and easily corrodes in moist atmosphere, is thus difficult to the requirement meeting construction material high-decoration and corrosion resistance.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, provide the spraying process for treating of a kind of aluminium alloy door window profile, method is simple, has good means of defence.
The spraying process for treating of aluminium alloy door provided by the invention window profile, comprises the following steps: (1) surface preparation, and adopt chromaking processing method, make Surface of profile form one deck chromaking film, the thickness of chromaking film is 800 mg/m
2-1000mg/m
2; (2) step (1) pretreated aluminium section bar is carried out drying under the temperature conditions of 50-60 DEG C; (3) powdery paints is coated to aluminium alloy section surface by powder spray rifle, form one deck and have protectiveness and ornamental organic polymer films, spray voltage is 70KV, and spray distance is 250-280mm, after spraying, through overcuring process, forms coating.
The spraying process for treating of aluminium alloy door provided by the invention window profile; its beneficial effect is, adopts chromaking processing method, makes Surface of profile form one deck chromaking film; effectively enhance the tack between aluminium section bar and coating, to aluminium section bar, there is good protective effect.
Detailed description of the invention
Below in conjunction with an embodiment, the spraying process for treating of aluminium alloy door provided by the invention window profile is described in detail.
Embodiment
The spraying process for treating of aluminium alloy door's window profile of the present embodiment, comprises the following steps: (1) surface preparation, and adopt chromaking processing method, make Surface of profile form one deck chromaking film, the thickness of chromaking film is 1000mg/m
2; (2) step (1) pretreated aluminium section bar is carried out drying under the temperature conditions of 60 DEG C; (3) powdery paints is coated to aluminium alloy section surface by powder spray rifle, form one deck and have protectiveness and ornamental organic polymer films, spray voltage is 70KV, and spray distance is 280mm, after spraying, through overcuring process, forms coating.
