How to deal with particles on the surface of paint, and what are the reasons for the appearance of g

If there are particles on the surface of the paint, it means that you did not mix evenly when mixing, if there are particles if you do not mix evenly, you can sand it off, and then repaint the topcoat to make up for it.

There are particles on the surface of the paint, and it should be polished and polished with 220 mesh fine sandpaper after it is completely dry.

This is generally a pollutant in the air.

You can do it in a polishing way.

Or treat the sanding with fine water matte paper.

In particular, there are particles on the surface that can be removed by shoveling.

Especially if there are grains on the surface, then you can buy that frosted troll.

The paint surface is gritty, which may be due to uneven spraying, or the surface of the component is smooth.

If there are particles on the surface of the paint, it is best to treat it with sanding.

1. Before the construction of the prepared paint, the paint should be filtered with a filtering tool to avoid the paint containing more impurities and affecting the construction quality of the paint.

2. After the paint is prepared, place it in a ventilated place for 10-20 minutes, and wait for the bubbles to disperse before use.

3. Choose the right construction weather, do not choose windy weather or dusty construction environment to construct, and do a good job of dust pollution prevention treatment for the paint that has just been constructed.

4. Before painting, treat the base layer of the paint well, such as filling the uneven places with putty, and then polishing them with sandpaper to smooth them, wipe off the dust, and then brush the paint.

5. During construction, choose the thinner and curing agent that match the paint to avoid the diluent or curing agent not fusing with the paint.

6. If the surface of the paint is rough, first polish it smooth with sandpaper, and then brush the topcoat again. If necessary, the polished paint film can be waxed and polished.

1. Grinding and dust removal are not clean.

Solution: Increase the grinding and dust removal efforts.

2. The compressed air of the compressor is not clean.

Solution: Compress all the air when compressing it.

3. The paint itself has particles.

Workaround: Replace the paint.

4. The spray gun is not cleaned in time.

Solution: Clean the spray gun.

Extended information: safety and environmental protection measures (1) A herringbone ladder should be erected according to the regulations when the height of the operation exceeds 2m. Inspections should be carried out before construction.

The herringbone ladder used should be placed in four corners and placed smoothly, and the corners of the ladder should be equipped with non-slip rubber pads and safety chains. Scaffold board is laid on the herringbone ladder, and the length of the scaffold board at both ends shall not be less than 20cm, and two people shall not operate at the same time in the middle of the scaffold board. When the ladder is moved, the operator must come down, it is strictly forbidden to stand on the ladder and step on stilts, and the hinge at the top of the herringbone ladder is not allowed to stand people, and the scaffold board is not allowed to be laid.

The herringbone ladder should be checked frequently, and it should not be used if it is found to be cracked, rotten, loose, or lacking. (2) Before construction, workers should be concentrated on safety education and made a written disclosure. (3) It is strictly forbidden to set up a paint material warehouse at the construction site, and the paint warehouse outside the site should have sufficient fire protection facilities.

4) There should be no fireworks safety slogans on the construction site, and a full-time safety officer should be set up on the site to supervise and ensure that there is no open flame at the construction site. (5) Try not to leave paint materials after finishing work every day. The remaining paint is not allowed to be dumped indiscriminately, and should be collected and disposed of centrally.

Waste is classified and consumed according to environmental protection requirements. (6) The on-site cleaning shall be carried out by a special person to sprinkle water, and there shall be no dust pollution. Grinding dust.

Solution (1) Before blending the good paint, it must be filtered through a filter cloth to remove debris. (2) After the paint oil is blended, it should stand for 10-20 minutes. (3) The uneven part of the base layer should be filled with putty, and then sandpaper should be used to polish it smoothly, and then the paint should be brushed after the dust is wiped off.

4) Use a matching diluent and curing leakage. (5) The surface of the coating film has been rough, which can be sanded smooth with sandpaper, and then brushed with topcoat.

What should I do if there are always small particles on the paint surface after painting? The spray paint is not smooth and grainy, which may be that the bottom layer is not polished and smooth; It may also be that the sprayed paint layer is too thin or the construction environment is poor, and dust falls after spraying; It can also be that the paint is not suitable for viscosity, resulting in poor spraying results. For the painted particles, the formal treatment is polishing and waxing.

The following is the relevant information: 1. There are reasons for small particles: generally there are several reasons for this situation, the base layer is not well handled, there is no polishing and smoothing, the paint quality is wrong, the construction method is wrong, and the spray gun is not cleaned.

2. Self-spraying paint: aerosol paint, usually composed of aerosol cans, aerosol valves, contents (paint) and projectiles, is a kind of paint that is filled with high pressure after the paint is processed by a special method to facilitate spraying, also known as manual painting. 2019

Summary. The solution to spraying paint with particles: 1. Clean and wipe the surface of the body; 2. Use a polishing machine with polishing powder for polishing; 3. Wax the car.

Usually should develop the habit of regular maintenance, should pay more attention to paint maintenance, some paint maintenance items such as: waxing, glaze, coating, crystal plating, etc., can protect the paint to a certain extent. The spray paint is not smooth and grainy, it may be that the bottom layer is not polished and smooth, or it may be that the sprayed paint layer is too thin or the construction environment is poor, and the dust falls after spraying, or it may be that the paint viscosity is not suitable and the spraying effect is not good.

For the particles after painting, the formal treatment is local grinding, and the painting is re-painted after the treatment is flat, and then polishing and waxing can be carried out.

Usually should develop the habit of regular maintenance, should pay more attention to paint maintenance, some paint maintenance items such as:

Waxing, glazing, coating, crystal plating, etc., can protect the car paint to a certain extent. The spray paint is not only slow and smooth, but it may be that the bottom layer is not polished and smooth, or it may be that the sprayed paint layer is too thin or the construction environment is poor, and dust falls after spraying, or it may be that the paint viscosity is not suitable resulting in poor spraying effect. For the particles after painting, the formal treatment is local grinding, and the painting is re-painted after the treatment is flattened, and then the polishing and waxing treatment can be called.

Hope it helps.

Dear, hello, I've kept you waiting, I'm happy to answer for you, hello, there are several reasons for spraying paint particles: 1The paint is too thick or too thin:

If the paint is too thick, the nozzle channel will be blocked, and the sprayed paint particles will become larger; If the paint is too thin, the sprayed paint particles will become smaller. Therefore, the ratio of thinner should be adjusted appropriately according to the viscosity of the paint. 2.

Bad nozzles: If the nozzles are broken or not cleaned, the paint will be sprayed out and turned into pellets. Therefore, the nozzle should be cleaned frequently to ensure that the paint is sprayed smoothly.

3.Insufficient gun pressure: If the pressure of the spray gun is not enough, the paint will drip down like water, forming particles.

The pressure of the spray gun should be adjusted to ensure that the speed and pressure of the paint are sprayed consistently. 4.Impurities on the surface of the paint:

If there are impurities on the surface of the paint, such as dust, grease, etc., the sprayed paint particles will also be affected. Therefore, before painting, the working surface should be cleaned to ensure that the paint surface is smooth. 5.

Too high or too low a temperature difference: A temperature that is too high or too low will affect the effectiveness of the paint. Before painting, you should choose the appropriate ambient temperature according to the requirements of the paint.

In order to avoid particles in the spray paint, we can also test the spray before painting, and adjust the parameters of the spray paint according to the effect of the test spray to ensure that the effect of the spray paint meets the requirements. In addition, in the process of painting, you should pay attention to safety and wear protective equipment to avoid the harm caused by spraying paint to the body.
