The car is painted all over the car, and if you don t dismantle something, you have to spray somethi

Gun outlet is lowered. The amount of paint is also lowered, first spray 1 time to each corner, walk slowly and then spray 4 door inner frames 3 times. Wait until it is completely dry. Increase the amount of air and paint, spray the whole car 3 times, and then polish it after 15 days!

No, you don't. Even if the scratches are small, when you go to the 4S shop or the outside repair shop, **will be the same as a large area of scratches**, because the 4S shop is to ensure that the car's car skills will not have the problem of color difference, so it will be sent to grind the whole part of the car shell where the scratches are located, to do the overall painting, then for small scars, it is not worth it to do the spray paint.

Car painting refers to the application of a layer of paint on the surface of a car to protect the car. Automobile painting is generally baked paint. In a car factory, the frame and body are welded, and the next process is painting.

Automobile painting includes: ordinary paint; metallic paints; pearlescent paint; Varnish; Matte lacquer.

There is no need to remove the paint. In other places, when you draw, you will cover it with newspaper. In one method, air pressure is passed through a spray gun to disperse uniform and fine droplets onto the surface of the coated object. Special attention should be paid to safety when painting to prevent inhalation and ** contact.

Automobile painting refers to the application of paint on the surface of the car to protect the car. Baking paint is generally used for car painting. In the car factory, the frame and shell are welded, and the next process is painting.

There are plain lacquers, metallic lacquers and pearlescent lacquers. Automobile coating process: scraping putty, polishing, painting, etc.

Ordinary paints are the simplest, resins, pigments and additives.

Metallic paint, also known as metallic glitter paint, is a popular automotive topcoat. Its lacquer base contains fine aluminum particles. After the light hits the Aluminium particles, it is reflected by the aluminium particles through the air film.

Therefore, it looks as if the metal is glowing. This metallic glitter paint gives a pleasant, light, and novel feel, so it's very common.

Pearlescent paint, also known as mica paint, is also a popular automotive topcoat. The principle is basically the same as that of metallic paint. It replaces aluminum particles with stove mica.

Mica pigments coated with titanium dioxide and iron oxide are added to its paint base. When the light hits the mica particles, it first takes on the colors of titanium dioxide and iron oxide, and then complex refraction and interference occur in the mica particles. At the same time, mica itself has a special and transparent color.

In this way, the reflected light has a pearl-like sparkle.

Car painting, spray does not spend the method of prudence:

1. The spray gun should be good, and the dilution of the paint should be diluted according to the temperature, slightly thinner in summer and slightly thicker in winter. When spraying, the fan shape should be adjusted to a moderate size, the width is large, and the cross spray is best sprayed diagonally.

2. First cover the part of the putty after repair, and then spray it evenly as a whole, the main thing is that the gun paint must be evenly sprayed, and the gun should be stable, pressed without omission, and not heavy gun.

3. The rarity of the paint, stir the paint when adjusting, and use the ruler to take it out, and the thin line of paint can be sprayed, and the distance is not too close to about 30 centimeters when spraying.

4. The ratio of paint should be accurate, don't look at the almost poured in, this is not good, the spray gun should be easy to use, the fan surface should be large, the amount of paint should be controlled and cracked, the air pressure of the environmental protection spray gun is 2, and the spraying distance is 160-180, and the speed of the gun should be uniform every second.

1) Purpose of configuration. The paint booth is one of the indispensable and important equipment for automobile repair and coating operations. The purpose of the equipment paint booth is to provide a clean, safe and well-lit painting environment for automobile painting construction, so that the spraying construction is not disturbed by dust, ensure the quality of painting, and limit the volatile paint mist to a limited space to reduce environmental pollution.

2) Technical requirements for the paint booth. The air entering the paint booth must be carefully filtered to ensure that the air is free of dust. The air flow in the paint booth must flow from the ceiling to the floor in the direction of gravity, and the air must be exhausted from the floor and filtered into cleaner air.

Ensure that the air in the paint booth is converted twice per minute, so the indoor air flow rate should be. The air flow rate is too large, the paint loss is too much, the coating condition is poor, and the air flow rate is too small, which affects the normal volatilization of the solvent. It has good lighting conditions.

Make sure there is no negative pressure in the paint booth. This can be achieved by controlling the amount of air entering the booth and slightly more than the amount of air being exhausted. The noise level in the paint booth is not allowed to exceed 85db.

Meets fire protection requirements. 3) Classification of paint booths. The paint booth can be divided into two categories: dry and wet according to the different ways of removing paint mist and preventing dust from mixing.

Dry paint booth. The dry paint booth is mainly composed of a chamber, a filter, an exhaust pipe and a ventilator. It is characterized by simple structure, small paint loss, high coating efficiency, due to the non-use of water, reducing water treatment equipment, low cost, and is widely used by domestic small and medium-sized repair enterprises.

Wet paint booth. The wet spray booth is divided into four types: spray type, water curtain type, text type and rotary type. For the coating of high-end automobile topcoats, foreign countries mostly use literary or water spin spray booths, and rarely use them in China.

4) Maintenance of the paint booth. All preparations before painting must be carried out outside the paint booth. The filter must be checked frequently and replaced at the prescribed time.

Check the barometer reading every day, grasp the air pressure range in the paint booth, and strictly prohibit negative pressure. The dry paint booth should moisten the ground before spraying to prevent dust. Regularly inspect the lighting and replace weak or burned light fixtures.

Lubricate and maintain the exhaust fan and motor regularly. Pay attention to personal hygiene, and it is strictly forbidden to wear dirty clothes into the paint booth. After each painting operation, it should be thoroughly cleaned, and the relevant equipment in the paint booth should be maintained and cleaned.

The car can be painted itself. The steps are as follows:

1.Wash the body with clean water, smooth it with sandpaper with skids, and sand the scratches with water until the edges are smooth and thick.

2.Use a pad to apply the patch evenly to the scratched surface until completely dry.

3.After drying, sand the patch with sandpaper dipped in water until the surface of the patch is parallel to the paint surface.

4.Plug the area around the scratch and start applying.

5.When spraying, the distance from the sprayed object is about 20cm. Press the nozzle to spray evenly, and the effect of multiple spraying is better.

What are the precautions for car painting:

1. Attention should be paid to identifying the color of the original brand car paint. The first thing to pay attention to when dispensing paint is to obtain the primary color according to the paint code of the automobile manufacturer, so as to reduce the difference between the maintenance paint and the finished paint formula used by the original automobile manufacturer.

2.Factors that affect the color of a car in automotive coatings. Different paint components have different colors, and the paint formula of automobile spray paint is not exactly the same as the pigment in the first paint formula used by automobile manufacturers.

At this time, it cannot be repaired in time to look the same as the original paint in sunlight or simulated sunlight, but there will be chromatic aberration when looking at another light source. Millions of car purchase subsidies.
