Can the surface of aluminum alloy be painted, and can aluminum alloy doors and windows be painted?

1. Preparation and conditions before spraying:

1.Weather conditions: The coating must be applied under the conditions of fine weather, the construction is prohibited under the conditions of rain, fog, snow and large dust, the optimal temperature for spraying application is about 25, and the humidity is below 80%RH.

2.Substrate treatment: Aluminum alloy substrate should be polished, oxidized and other treatments. The surface should be derusted and degreased, and ensure that it is clean and dry without dirt, and the dust should be removed and filled before the paint can be sprayed, and the substrate should be dried before spraying.

3.Spray gun standard: spraying can be selected with a spray gun of caliber, and the pressure of the spray gun should be adjusted to 3-4kg cm2. The fog amplitude is adjusted to medium air pressure to 3-4kg cm

2. Spray the surface of the workpiece as much as possible and spray it evenly 2-3 times. Adjust the amount of oil appropriately, the amount of oil is too small, and particles are easy to appear on the surface of the paint film.

4.Air compressor: Before construction, the air compressor and filter should be dewatered to avoid pinholes in the paint film.

Second, the primer spraying:

1.After achieving good surface treatment effect on the surface of aluminum alloy, (no oil, no dust, and a certain roughness on the surface), you can spray a special epoxy zinc-rich primer for aluminum alloy. The primer has good adhesion to aluminium alloy surfaces, especially the two-component zinc epoxy yellow primer.

The paint has the unique high adhesion, toughness, hardness and other excellent epoxy paint, and good supporting performance.

2.Mixing ratio: Primer:

Primer Curing Agent: Thinner 4:1:

Amount. Stir the paint for 5 minutes until homogeneous before mixing. Use a more accurate electronic scale to weigh according to the mixing ratio to ensure the accurate proportion.

Once the paint is mixed, stir it with a clean aluminum strip or iron rod until it is completely homogeneous. Be careful not to mix other kinds of paints and solvents during construction, and pay attention to keeping the spraying environment clean. After mixing, it can be used up within 2 hours, and the ambient temperature is greater than 30, and the usable time after mixing should be shortened.

OK! The role of paint is anti-rust, anti-corrosion and decoration, why the surface of the general aluminum plate is not painted is because aluminum is more difficult to oxygen and corrosion, plus the white is not ugly, so it is not painted! But if you like other colors, you can paint it!?

Hello, dear, the oxide paint on the surface of the aluminum is easy to fall off the aluminum surface adhesion is poor, it is difficult to spray paint directly and have good adhesion to the aluminum surface, even if it is barely painted, it will soon fall off. Then you need to make a layer of primer on the aluminum alloy substrate to increase the adhesion of the paint, and then you can use ED1000 epoxy primer in the spraying topcoat, which is a special primer for aluminum alloy, with very good adhesion and a variety of characteristics: 1. Strong adhesion to aluminum alloy, and can also be used for smooth surface substrates such as stainless steel, aluminum plate, galvanized sheet 2, no need to blast or polish the metal surface, just use organic solvent to wipe and remove oil stains, which can be constructed, saving time and effort 3, salt spray resistance up to 1000 hours, good anti-corrosion and rust ability 4, It can be used with fluorocarbon paint, polyurethane paint, epoxy paint, acrylic paint and other topcoats5, with different types of water-based paint and oil-based paint, and different coating requirements.

The aluminum alloy surface can be painted.

It can improve the surface decoration of aluminum alloy, as well as anti-corrosion. The surface of the aluminum alloy needs to use a special primer to improve the adhesion, because the surface of the substrate is smooth, and most paints do not adhere firmly, which is prone to the problem of paint falling off. ED1000 epoxy bottom Wushan jujube paint is a special paint for aluminum alloy, with strong adhesion to smooth metal surfaces.

Treatment method: ED1000 epoxy primer can be used for aluminum alloy, aluminum plate, galvanized sheet, stainless steel and other smooth substrates, the paint film and the substrate adhesion is strong, can effectively ensure that the coating film does not fall off, does not remove the paint, salt spray resistance up to 1000 hours, excellent corrosion resistance, can well protect the substrate, aluminum alloy surface does not need to be sandblasted or sanded, only need to remove oil stains can be constructed, saving time and effort.

The coating does not contain heavy metals such as lead and chromium, and there is no harm to the environment and health, the surface of the aluminum alloy is removed from the oil stain first, and the ED1000 epoxy primer is painted, and the topcoat is used after the primer is dried, and the polyurethane topcoat and acrylic polyurethane topcoat can be selected, the gloss of the topcoat is high, the color is diverse, and it is not easy to change color, which can protect the aluminum alloy and play a good decorative effect.

Of course, the outside of the aluminum alloy can be painted or sprayed, if it is used in a small area, it is recommended to use Chenyang's multi-functional paint water-based blending paint. At the same time, due to the material, the foundation needs to be treated before painting or painting, otherwise it is easy to lose the paint. Substrate Treatment:

The aluminum alloy substrate should be polished, oxidized and other treatments. <>

Summary. Alloys based on aluminum with a certain amount of other alloying elements added are one of the light metal materials. In addition to the general characteristics of aluminum, aluminum alloys also have some specific characteristics of alloys due to the different types and quantities of alloying elements.

Is it OK to base with epoxy paint.

Dear, no, epoxy paint Chongshi Town is suitable for painting the inner wall of the oil tank, the surface of various light metals and cement structures indoors and outdoors, and it is not recommended that you use it as a primer.

Aluminum alloy doors and windows.

The surface of the profile is sprayed with electrophoresis and painted, and the material is powdered with powder.

Profiles, fluorocarbon paint.

Spraying profiles. Electrophoresis coated with hail coarse material.

As a new type of low-pollution, energy-saving, resource-saving, start-up protection and anti-corrosion coatings, it has the characteristics of smooth coating film, good water resistance and chemical resistance, etc., and is easy to realize the mechanization and automation of the coating industry, suitable for coating workpieces with complex shapes, edges and corners, and holes, and is widely used in the coating of hardware such as automobiles, automatic vehicles, electromechanical, and home appliances.

Electrophoretic coating can be fully mechanized and automated, which not only reduces labor intensity, but also greatly improves labor productivity.

It is suitable for a large number of assembly line operations.

The electrophoretic coating has high permeability and is completely dissolved or emulsified in water.

The formulated tank liquid has a very low viscosity and can easily penetrate into the bag-like structure and crevices of the coated object, which is especially suitable for the surface coating of special-shaped conductive materials.

Aluminum alloy can not be coated off the method:

1.First, buy a suitable paint. The quality of paint used for spraying aluminum alloy surface should be good. Before use, it is necessary to see if it is suitable for aluminum.

2.Before spraying, inspect the aluminum surface. When spraying, there must be no water and dust on the surface, otherwise the overall effect will be affected.

3.Also, after spraying, avoid water and allow it to dry for about 72 hours before use.

Parts that can be made of aluminum alloys in automobiles:

1.Car wheels.

The use of aluminum alloy wheels has a very obvious effect on reducing the fuel consumption of automobiles.

The car has four doors and two lids.

1.The four doors are four doors, and the two covers are the hood and the trunk lid, which are all parts of the body that are easily damaged. The aluminum plate has excellent deformation ability, and can absorb the impact force well when it is impacted by external forces, which protects the driver and passengers to a large extent.

Therefore, it is safer to use aluminum alloy for four doors and two covers.

2.Car chassis.

3.Aluminum alloys can also be used for bottom guard parts such as automobile suspension swing arms.

4.The fuel tank, radiator, and battery floor of new energy vehicles can also be made of aluminum alloy.

What kind of paint can be sprayed on the surface of aluminum alloy? Is fluorocarbon paint OK?

The surface of the aluminum alloy can be sprayed with fluorocarbon paint, and I will give you a complete fluorocarbon paint construction work. fluorocarbon coating in aluminum profiles. The process is mainly divided into 6 steps:

Pre-treatment-primer-coat--topcoat layer, a cover, a varnish layer, a curing treatment, and a quality inspection 1Before spraying the aluminum alloy profile, the surface of the workpiece should be degreased, decontaminated and chemically treated to produce a chromized film, which increases the adhesion and anti-oxidation ability of the coating and the metal surface, which is conducive to prolonging the service life of the paint film. 2.

Primer coating: As a primer coating for sealing the substrate, its function is to improve the anti-penetration ability of the coating, enhance the protection of the substrate, stabilize the metal surface layer, strengthen the adhesion between the topcoat and the metal surface, and ensure the color uniformity of the topcoat coating, and the thickness of the paint layer is generally 5-10 microns. 3.

Topcoat coating: The topcoat coating is a key layer of spray coating, which protects the metal surface from the erosion of the external environment, acid, rain, and pollution, and prevents ultraviolet rays from penetrating. In order to provide the decorative color required by aluminum, so that the appearance of aluminum meets the design requirements, greatly enhance the anti-aging ability, the topcoat coating is the thickest layer of paint in spraying, and the thickness of the paint layer is generally 23-30 microns.

4.Overprint coating: The main purpose is to more effectively enhance the ability of the paint layer to resist external erosion, protect the topcoat coating, increase the metallic luster of the topcoat color, and make the appearance more colorful and dazzling, and the coating thickness is generally 5-10 microns.

The total thickness of the three-spray coating - generally 40-60 microns, can be thickened if required. Overprint coat coating, also known as varnish coating, 5Curing treatment:

The three-spray coating generally needs to be cured twice, the aluminum enters the curing oven for processing, the curing time is 15-25 minutes, and the curing temperature is generally between 180 °C-250*C. Chlorine and carbon spraying plants (curium oil factories) have also changed the two curing during three sprays to one curing according to their own experience. 6.

Quality inspection: The quality inspection should be according to AAMA-605 standard. Strict quality inspection can ensure high-quality sprayed products.
