Problems solved by technology

At present, electrophoretic spraying is mostly used in the market to realize the surface treatment process of aluminum profiles for doors and windows. This method is likely to cause environmental pollution. The quality of the spraying process directly affects the adhesion, appearance, and moisture resistance of the coating. and corrosion resistance, as the best coatings adhere to carefully cleaned surfaces

Embodiment 1

[0019] A surface spraying process for door and window profiles, comprising the steps of:

[0020] S1. Use a grinder to polish the surface of the qualified door and window profiles. Immediately after grinding, put the door and window profiles into the acid solution at room temperature, soak for 3 minutes, lift the door and window profiles, drain the residual liquid, and quickly hang them into the washing tank for cleaning ;

[0021] S2. At room temperature, rinse the door and window profiles treated in step S1 with 100g / L NaOH solution. The NaOH solution is sprayed to the surface of the door and window profiles through the nozzle. The injection pressure of the nozzle is: 20MPa, and the flow rate is 50L / min;

[0022] S3. Hoist the door and window profiles treated in step S2, drain the residual liquid, quickly hoist them into the washing tank and soak for 20 minutes, then hoist them again, and rinse with clean water at a pressure of 20 MPa, and then in an environment of 40°C, Dr...

Embodiment 2

[0030] A surface spraying process for door and window profiles, comprising the steps of:

[0031] S1. Use a grinder to polish the surface of the qualified door and window profiles. Immediately after grinding, put the door and window profiles into the acid solution at room temperature, soak for 5 minutes, lift the door and window profiles, drain the residual liquid, and quickly hang them into the washing tank for cleaning ;

[0032] S2. At room temperature, rinse the door and window profiles treated in step S1 with 150g / L NaOH solution. The NaOH solution is sprayed to the surface of the door and window profiles through the nozzle. The injection pressure of the nozzle is: 140MPa, and the flow rate is: 160L / min;

[0033] S3. Hoist the door and window profiles treated in step S2, drain the residual liquid, quickly hoist them into the washing tank and soak for 30 minutes, then hoist them again, and rinse them with clean water at a pressure of 140MPa, and then in an environment of 5...

Abstract

The invention discloses a surface spraying process for a door window profile. The surface spraying process includes following steps: S1, polishing the surface of the door window profile, and putting the door window profile into normal-temperature acid liquid; S2, spraying a NaOH solution to the surface of the door window profile through a nozzle; S3, hanging up the door window profile after beingtreated in the S2 to drain residual liquid, hanging the same into a water washing tank for soaking for 20-30min, hanging up again, using clear water to flush at flushing pressure of 20-140MPa, dryingin environment of 40-50 DEG C for draining residual water; S4, spraying protection paint onto the surface of the surface of the door window profile to obtain a film of 5-15um in thickness, and curingthe protection paint, wherein air after being polluted by the protection paint needs to be filtered and purified in the process of spraying the protection paint. By polishing the surface of the door window profile to remove oxide thereon, the protection paint can be in close fit with the surface of the door window profile, thereby being less prone to shedding, so that waterproofness, wear resistance and corrosion resistance of the door window profile are improved effectively.

Description

technical field [0001] The invention belongs to the technical field of surface spraying of door and window profiles, and more specifically relates to a surface spraying process of door and window profiles. Background technique [0002] Because of its advantages in strength and processing, profiles have been widely used in the fields of building structures and manufacturing and installation. At present, electrophoretic spraying is mostly used in the market to realize the surface treatment process of aluminum profiles for doors and windows. This method is likely to cause environmental pollution. The quality of the spraying process directly affects the adhesion, appearance, and moisture resistance of the coating. And corrosion resistance, etc., because the best coatings are those that adhere to carefully cleaned surfaces. Contents of the invention [0003] The object of the present invention is to propose a surface spraying process for door and window profiles in order to so...
