It is better to spray or powder the aluminum alloy door

Spray well.

Powder coating is to spray powder coating to the surface of the workpiece with powder spraying equipment, under the action of electrostatic, the powder will be evenly adsorbed on the surface of the workpiece, forming a powdery coating, the powder coating is baked and leveled and solidified at high temperature, and the effect is different.

Fluorocarbon spraying. It is a kind of electrostatic spraying, but also a liquid spraying method, called fluorocarbon spraying, called curium oil, belongs to high-grade spraying, so the highest is higher, the spraying effect of powder spraying is better than the painting process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the cost is also under the same effect of painting.

Fluorocarbon spraying has excellent resistance to fading, frosting, corrosion resistance to air pollution, and UV resistance.

Strong, crack resistant and able to withstand harsh weather.

The environment is beyond the reach of general coatings, and the excellent quality fluorocarbon coating has a metallic luster, bright color and obvious three-dimensional effect.

Summary. Hello, it's good.

The best coating should be regarded as fluorocarbon spraying, but the ** is higher, the oxide material should not be selected as much as possible, the color will be black and discolored for a long time, and the aluminum alloy used for doors and windows is generally electrophoresis or spraying.

How about aluminum alloy door and window metal spraying.

Hello, it's good. The best coating should be regarded as fluorocarbon spraying, but the highest is higher, the oxidation material should not be selected, the color will be black and collapsed after a long time, and the discoloration will be more serious.

Will it fade.

Will it fade.

Will the metal spray peel off.

Aluminum alloy exterior painting is generally not falling 1, classified by type: manual painting and automatic painting 2, classified by car paint varieties: alkyd paint, acrylic paint, water paint.

The standard of spray painting, according to the volume (European Paint USA company standard), can be divided into 200 and 400ml two different capacities of spray paint. 3.According to the brightness, it is divided into high gloss (also called bright light), semi-matte, and matte (also called full matte).

4. The metal surface of the aluminum alloy can be sprayed after oxidation treatment, and the cans are all treated with volcans 5. Chemical oxidation treatment is adopted, which is suitable for pure aluminum and alloys containing MG, MN and Si, and can also be used for alloys with less Cu content, gray. The surface of the aluminum alloy film layer with high duralumin and Cu content or other heavy metals forms a powder, which can be used as the bottom layer of oil and paint6, and the electrochemical oxidation treatment is adopted, and the sulfuric acid anodizing process can be applied to the anodizing of all aluminum and aluminum alloy workpieces, and the obtained oxide film has high adsorption capacity and corrosion resistance, strong adsorption force, and is conducive to dyeing; High hardness, corrosion resistance, wear resistance, and its properties are affected by various factors such as sulfuric acid concentration, temperature, current density, oxidation time, stirring, additives, aluminum alloy composition, etc. It is widely used, such as building aluminum, parts that require special color and bright appearance and certain wear resistance, protection of aluminum alloy with high copper content, butt gas welding parts, etc., the disadvantage is that the electrolyte temperature is low when oxidizing, and cooling devices are required.

If it is necessary to improve the corrosion resistance and insulation of the oxide film, it is also necessary to carry out proper filling and sealing treatment.

The surface treatment of aluminum alloy doors and windows is now more common: anodizing, electrophoresis, powder coating, fluorocarbon spraying, etc.

Fluorocarbon spraying is a kind of electrostatic spraying, which is also a liquid spraying method, which is called fluorocarbon spraying, and is called curium oil in Hong Kong. It belongs to high-grade spraying, so it is higher and has long been applied abroad. Fluorocarbon spraying has excellent resistance to fading, frosting, air pollution (acid rain, etc.), corrosion resistance, strong UV resistance, crack resistance and the ability to withstand harsh weather environments.

It is beyond the reach of general paints.

Generally speaking, the weather resistance of these surface treatments is gradually increased according to the previous arrangement, but it cannot be generalized and should be analyzed specifically, because there are many influencing factors such as the thickness of the coating, the coating material, and the process.

In addition, it depends on whether the project is located coastal or inland, the degree of corrosion of the surrounding environment and other factors to determine the type and thickness of the coating you choose.

I haven't heard of the aluminum alloy doors and windows sprayed on the spot, and they are all sprayed profile processing.

However, if you want to spray, it should only be sprayed with fluorocarbon paint.

Spray zinc yellow primer and then spray paint with better weather resistance.

1. Old-fashioned bare aluminum door and window spraying: clean the doors and windows with detergent - protect the wall, glass and non-painted surfaces with masking paper and protective film - spray DuPont epoxy primer - spray weather-resistant topcoat.

2. New broken bridge sprayed aluminum doors and windows: clean the doors and windows with detergent - protect the wall, glass and non-painted surfaces with masking paper and protective film - wipe the surface to be coated with DuPont special treatment solution (note: without special treatment liquid, the topcoat is easy to fall off) - spray DuPont topcoat.

I have tried many times, due to insufficient ordering, or maintenance without the same color of the material and need to spray themselves, asked a lot of peers and spraying manufacturers, tried a lot of varieties of paint, but none of them are satisfactory, not a few days on the peel off or the coating is not wear-resistant, the most important thing is that the site spray can not pickle, if not the construction period is too urgent, it is recommended not to spray yourself, a small amount can also find the manufacturer to spray, really want to spray must be baked with a sun lamp, so that it can be used for a period of time.

The mistake is that the powder can be sprayed on the spot.

In the home decoration, the aluminum door has high requirements for safety, and in order to keep the surface of the aluminum door from corrosion, it is often necessary to achieve it through painting, which can increase some decorative effects. In order to ensure the effect of aluminum door painting, special attention should be paid to the purchase of spray paint. Aluminum art gate is more common in the application of aluminum art gate, to ensure the effect of painting in addition to the selection of paint, the method of painting also has high requirements.

Next, I will introduce the detailed process of aluminum art door painting.

Aluminum art door painting process:

1. Grinding: Find a cuboid that can be held by hand. Wrap one of the relatively flat sides in sandpaper, press it with your hand and polish it.

The order of direction of the grinding plane is: first horizontal and then vertical. When sanding, it is necessary to go up and then down, first outside and then inside, and the selection of sandpaper is coarse and then fine.

The corners and shapes of the aluminum art gate and the details have to be used by hand. Why polish? On the one hand, it is to remove impurities from the ** paint and paint surface, and on the other hand, it is to increase the adhesion of the new paint.

2. Preparation before painting: After grinding, see if there is an uneven place in the aluminum art door, if so, use putty to level and polish it again to a flat state. The area around the gate and the floor are then protected to prevent paint from contaminating these areas.

And wipe the aluminum door with a wet towel with very little water. Stir the bucket paint well with a small stick, and do not move your hands too fast to prevent spilling.

3. Paint: When brushing the first wood paint, adjusting the primer is a very important process, and the primer should also know the density of the wood, those harder wood has a high density, the primer can be adjusted a little thinner, and the soft wood primer should be adjusted to be viscous. When you start to paint, you should paint evenly along the texture of the wood, don't paint too thickly, and wait until the wood paint is completely dry and sandpaper, polish until you feel smooth to the touch, and there is no protrusion, and then wipe it with a soft damp cloth several times, and finally wipe it dry.

The use of brushing can make the penetration depth of wood wax oil greater, and also speed up the speed of construction. After brushing, you can cover the wood paint of the first brush, and then use more than 500 mesh of water sandpaper to follow the direction of the paint, and polish it evenly. The use of scrubbing can save the amount of wood paint.

Wait until the second or last lacquer surface is dry, immediately wipe the surface of the wood with a clean cotton cloth to make the surface of the wood smooth. After brushing the third paint, it should be polished with finer water sandpaper, dipped in water and polished, and the strength of the polishing should be uniform, not too heavy or too light. There is no need to polish after the last paint, you can apply a layer of aluminium door protection wax.

Add the number of wipes, and polish with fine sandpaper after each coating, and wipe with a thin wipe and surface drying for the last time to get the effect of high-grade aluminum art doors.
