Description
Technical Field
The invention relates to the field of composite material surface treatment, in particular to a sand blasting method for a glass fiber reinforced composite door and window profile.
Background
The sand blasting process is a process of cleaning and roughening the surface of a substrate by using the impact action of a high-speed sand blasting medium, i.e., a sand flow. Compressed air is used as power to form a high-speed jet beam to jet a sand blasting medium to the surface of a workpiece to be processed at a high speed, so that the appearance or the shape of the outer surface of the workpiece is changed, and the surface of the workpiece obtains certain cleanliness and different roughness due to the impact and the cutting action of the sand blasting medium on the surface of the workpiece, so that the mechanical property of the surface of the workpiece is improved, the fatigue resistance of the workpiece is improved, and the adhesive force between the workpiece and a coating or an adhesive layer is increased.
Disclosure of Invention
The invention provides a sand blasting method for a glass fiber reinforced composite door and window profile, which comprises the following steps:
(1) uniformly mixing the corundum sand and the antistatic resin sand to obtain a sand blasting medium
(2) Fixedly placing the cleaned glass fiber reinforced composite door and window profile on a workbench, wherein the surface to be treated is upward;
(3) aligning a nozzle of an air sand blasting machine to the surface to be treated of the glass fiber reinforced composite door and window profile, starting the sand blasting machine, and performing sand blasting treatment on the surface of the glass fiber reinforced composite door and window profile by using uniformly mixed corundum sand and antistatic resin sand as sand blasting media;
(4) cleaning the glass fiber reinforced composite door and window profile subjected to sand blasting treatment;
(5) and drying to obtain the surface-treated glass fiber reinforced composite door and window profile.
The fineness of the corundum sand is 80 meshes.
In the step (2), the glass fiber reinforced composite door and window profile is cleaned by wiping the surface of the glass fiber reinforced composite door and window with non-cotton wadding cloth soaked with a solvent, and the glass fiber reinforced composite door and window profile is parked for 5-10 min after cleaning is finished, so that the solvent is completely volatilized.
The solvent is any one or more of isopropanol, acetone and ethanol.
A sand blasting method for a glass fiber reinforced composite door and window profile comprises the following steps:
1. the device is provided with a one-touch activation means. The starting sequence is a dust removal fan, sand is stirred upwards, sand is stirred downwards, a spray head swings, sand is blasted and is conveyed, and the stopping sequence is the reverse sequence.
2. Adjusting the parameters of the sand blasting machine: according to different processing materials, the amplitude of the spray gun is as follows: 40-50 times/min, the spraying amount of the corundum sand is as follows: the material processing speed of 20-25 kg/h (calculated by actual consumption) is as follows: 0.7-1 m/min. The normal operation cannot be performed when the air pressure is generally 0.8MPa and the operating pressure is 0.7MPa or less than 0.35 MPa.
3. The sprayed material is selected, and the front bracket, the rear bracket and the positioning wheel are corrected within a proper range, so that the material can pass through smoothly.
4. The transport frequency is typically set at 16Hz and the wobble frequency at 45 Hz.
5. And observing the sand adding hole, wherein the material of the inner sand is low, replenishing in time, cutting to note that the sand injecting hole cannot be exposed, and the consumption is generally 25 kg/h.
6. The blowing devices are additionally arranged at the front and the rear of the machine, and the blowing devices are arranged at the north side when the machine runs to the north, and are arranged at the south side when the machine runs to the south.
7. In order to prevent sand from accumulating in the bin, the four corners are provided with blowing devices.
8. The side of the cutting and recording lifting device is provided with an observation hole and a sand discharge hole, and sand is forbidden to be added at the observation hole and the sand discharge hole.
The invention adopts uniformly mixed corundum sand and antistatic resin sand as a sand blasting medium to perform sand blasting treatment on the surface of the composite material, the method improves the surface roughness of the composite material, does not damage fibers, and the obtained composite material has good antistatic, bonding and paint spraying mechanical properties on the surface and can be widely applied to high-performance structural materials.
Detailed Description
