Just learning how to spray car paint as quickly as possible? What is the difference between plain pa

Spraying with water does not practice technique. The only shortcut to learning to paint quickly is to spray more, whether it's plain or metallic. At the beginning of the lesson, you first practice with a primer.

The difference between plain color and metal is metal bands, particles, and pearls. The general plain color does not have varnish, and the metal Qi basically has varnish. Metal is not plain and easy to spray.

If you spray the primer freely, the plain color is basically the same. Don't use plain color as a primer. The primer is air-dried and dries relatively quickly.

Plain drying is relatively slow, plain 10 15 minutes spray once. Metallic paint must be sprayed in the case of someone guided. When you finish spraying the base color, you must ask the master to see if you are spraying varnish.

It's good to spray it twice. Painting is not very difficult .

Metallic paint dries quickly, while plain paint dries slowly.

Wait a little after the plain paint is sprayed once. In the next spraying, to prevent sagging, the cover should not be too thick, spraying too much will lose light, generally 1-2 times on the line.

Metallic paint can be flash sprayed, using the process of dry spray drying, the front treatment must be fine, and the glaze must be covered with primer when it is red and gray, otherwise it will produce edge marks or pan bottom.

You first take the water spray practice, so that it does not flow down, relying on more practice, the metallic paint has pearls in it, it will flash in the sun, and it looks better than plain paint.

How to spray metallic paint so that it won't spent.

1. Look at the appearance: the appearance of the paint directly affects the decorative effect, if the appearance of the paint is not smooth, uneven, and even the pattern is not clear, spray it on the body, it is easy to reduce the temperament and grade of the car. Therefore, when choosing a car paint, you can try the effect first to see if the appearance effect of the decoration meets the requirements.

2. Look at the hardness: high-quality car paint has enough hardness to avoid scratching the surface paint of the car because of the sand and gravel on the road surface during the driving process.

3. Look at the color: the color of the car paint is very important to the car, and the color is not selected well not only will affect the appearance of the car, but also can not reflect the owner's taste. In terms of color selection, you can choose according to your preferences or the current trend.

4. Look at the weather resistance: the use environment of the car is not static, and you can't rest in sunny, rainy and snowy days, and you have to serve the owner diligently. Therefore, automotive paint should withstand the alternation of hot and cold temperatures and have good weather resistance.

Otherwise, the paint surface is prone to cracking due to temperature changes.

In addition, remind new car owners, if you have just started a new car, don't be in a hurry to wax first, because there are many new cars that are basically a few days after leaving the factory, and the paint is baked, and it takes a while to become firm and hard, so the waxing of the new car generally has to wait until three months later. If you want to touch up the paint on a daily basis, it is best not to wash the car for less than a week.

Ordinary paint, ordinary paint is also known as solid color paint, as the name suggests, this is the most basic car paint. The common colors of ordinary paint are black, red, white, etc., the biggest feature of this kind of paint is that the color is single and pure, and the production cost is generally relatively low, which is suitable for the majority of ordinary household economic models.

Metallic paint, metallic paint, in fact, is a car paint with metal powder in the car paint, so as to make the body look shiny and enhance the visual effect of the paint. Metallic paint has a feature, under different angles, under the illumination of light, the whole car color and even the contour of the model will show different shapes. As a higher-grade level of paint, metallic paint is generally used for models with a price of about 200,000 yuan or more.

First of all, the most basic requirement for automobile spraying is that the air pressure is basically stable, and the barometer is 6-8! Then adjust the spray gun sector size according to your habits! When spraying again, each spraying direction should be 1 3 in the previous direction, and the spraying can be uniform. The specific steps are as follows.

1.For the first time, the varnish should be completely sprayed and should glow, with a slightly longer flash in the middle. In this way, the first pass mainly plays the role of polishing the paint surface, paving the way for the second coat of varnish, so that the second pass of slightly thicker varnish is sprayed evenly to achieve the best leveling effect.

Some people say the first spray: don't spray the first time, the varnish should be thinner, the gun should go evenly, and the light should come out for the first time. If you are afraid of flowing, you should stay away from the gun (the purpose of the longer distance is to be afraid of walking unevenly or slowly, the paint is easily sprayed into a pile, so it will flow, of course not too far, usually 10 cm to 25 cm, this is your control).

In the middle, wait for the flash drying time and barely the same (about 5 to 10 minutes) when the fingers are pressed without stretching.

2.The second time can be sprayed in two parts. Spray 80% first.

Don't stop. Pull the gun apart and spray it directly, once with 30% varnish. If you are afraid of flowing out of the gun, you should slowly grasp the feel, and when spraying the handle position, you should sweep the gun quickly, otherwise the handle position is easy to flow out.

When spraying, it is about 20 cm away from the object to be sprayed. Press the nozzle to spray evenly, and the effect of multiple spraying is better. When spraying multiple times, remember to keep the interval between the second spray at least 10 minutes, and let the paint dry before spraying to avoid sagging.

If sagging occurs, the sagging is sanded with sandpaper after drying, and covered with long-distance spray paint after sanding. Once the paint is completely dry, a coat of varnish can be sprayed to increase brightness, protect the painted surface and make it wear-resistant. The correct spray trajectory is perpendicular to the surface of the workpiece and can be closer together for a wetter, deeper and thicker coating.

For a drier, lighter, thinner coating, the distance can be longer. When a high uniformity of paint thickness is required, the cross-spraying method should be used, followed by horizontal spraying.

Finally, the most important thing is the order of drawing. The best effect is that the orange peel of the whole vehicle is uniform and the residue is small. If the order of the guns is not reasonable, even if it is sprayed well, it will be scratched by fake paint. Keep the door active (this door is on fire) and finally reduce the air pressure.

Car painting requires specialized skills, and it is best to have a professional do the painting to protect the car body. Polishing techniques are also required after painting.

You can go to some professional stores for the corresponding painting, the effect can be said to be very good, you should choose the price of about 3000 yuan.

When the car is painted, it should be paid attention to uniformity, and it should be sprayed evenly on the surface of the car, so that the effect will be better.

Today, the car maintenance socks technology network will give a brief introduction to friends. What about car painting? Pay attention to the car livery.

When a car is exposed to sunlight, wind and rain for a long time, the paint will inevitably fade. Sometimes cars are unavoidable. At this time, the paint can be restored by painting the vehicle.

What are the precautions for car painting? The following car maintenance technology network will give friends a brief introduction.

What to pay attention to in car painting - choose a better old imitation car repair shop.

To paint and finalize the car, you should choose an auto repair shop with a good reputation and good technology, not necessarily a 4S shop. **It's outrageous, some of the experienced repair shops I opened myself are good.

What to pay attention to in car painting Introduction: The composition of paint.

Most automotive paints have four basic components: film-forming substances (resins), pigments (including body pigments), solvents, and additives.

1) Film-forming substances are the main components of coatings. Its function is to keep the pigment shiny, strong, long-lasting, and adhere to the surface of the object. It is this substance that determines the type of paint.

It is made from most natural resins (such as rosin), artificial resins (such as dehydrated malic acid resin), and synthetic resins (such as methyl methacrylate, polyurethane, polystyrene, polyvinyl chloride, etc.). ) modified with dry or semi-dry oil. Plasticizers and catalysts are often added to regulate and improve their durability, adhesion, corrosion resistance, abrasion resistance and toughness.

2) Pigment is one of the two non-volatile substances in coatings, which gives color and durability to the topcoat, and at the same time makes the paint have hiding power, improve strength and adhesion, change gloss, improve fluidity and coating performance.

3) The solvent is a volatile component in the paint, and its main function is to fully dissolve the resin in the paint film, so that the paint can be applied normally. High-quality solvents can improve the coating performance and film properties of the topcoat, enhance the gloss, and reduce the moiré of the paint, thereby reducing the polishing effort while contributing to more accurate color matching. In addition to the solvents already present in the paint, it also acts as a thinner to dilute the paint so that its viscosity is suitable for the coating requirements.

4) Additives. Coating technology has changed a lot in the last decade, and the use of additives is becoming more and more common. Although additives make up less than 5% of coatings, they play a variety of important roles.

Some hardeners can speed up drying and improve gloss, some retarders will slow down drying, and some matting agents will reduce gloss. Some additives have a combination of functions: reduce wrinkles, speed up drying, avoid whitening, and improve chemical resistance.

There are some things in this world that can't be done, but you must know that these things you know may become your capital in the future, so don't pay attention to car paint. That's all for today's introduction to Shihao Fiber, so how much do you know about car painting?

At present, there are more and more car production, and many car lovers will choose to paint the car to protect the car, so how to spray the car paint to have a good effect?

1. Before painting the car, it is necessary to ensure that the surface of the car has a certain roughness, if the surface of the car is too smooth, you can use 600 sandpaper to rub the body to make the body rough, the purpose is to facilitate the car painting, the adhesion of the paint is stronger, and the paint is not easy to fall off.

2. Don't be too close to the car body when painting, about 20 cm away from the car under normal circumstances, so as to ensure that the painting is more uniform, and the effect of a small number of multiple paint spraying is better.

3. When spraying paint for the second time, it is necessary to pay attention to the interval between the two spraying should not be too short, at least more than ten minutes, and wait until the paint is all dry before the second spraying.

4. After spraying the car paint, in order to make the car paint more durable and durable, you can apply a layer of oil after the paint is dried after the painting is completed, and the oil can also increase the luster of the body.

Car paints are generally baked paints. In the depot, after the frame and body are welded (and sometimes repaired by hand), the next process is painting. In general, the first is the primer.

Dip the bare car shell into a syrup-like paint tank and remove the drying primer; Then send it to the dust-free workshop and spray the paint with the electrostatic spraying process. It is then dried at a temperature of around 200 degrees. If you are elegant, you will apply another layer of varnish.

In this way, the painting process is complete. There are several types of general topcoats: ordinary paint; metallic paints; Pearlescent lacquer.

Needless to say, ordinary lacquer, resins, pigments and additives. Metallic paint has more aluminum powder; So it looks bright when it's done. The pearlescent lacquer is added with mica grain.

Mica is a very thin piece of things, so the reflection is directional, and it has a colorful effect. If it is metallic paint with a varnish layer, the paint of the car will look very bright and beautiful. In terms of color, white is undoubtedly the cheapest.

For example, world-class brand red pigment is about 25 times more expensive than world-class brand titanium dioxide; The amount of titanium dioxide in white paint is about 5 times that of red pigment. As a result, red paint costs up to 5 times more for color than white paint. That's why there are so few varieties of colors in some domestic cars:

Simple and low at the same time.

The so-called solid color paint is a colored paint (white and various toning paints) with hiding power, and the hiding power in the solid color paint is nothing else, it is organic and inorganic pigments, such as titanium dioxide, benzidine yellow, phthalocene blue, permanent red, lisol red, carbon black and so on. It is composed of resins, pigments and fillers, additives and solvents. In addition, there are certain ingredients such as leveling agent, defoamer, anti-ultraviolet and so on.

Different paints have different functions and functions due to the different resins they compose. For example, car refinish paint is composed of acrylic acid polyurethane, so it is also called acrylic acid polyurethane paint.

Solid color paint is made of pigments, and there is a distinction between colors; Plain paint, on the other hand, is made with metal powder, including aluminum powder or aluminum powder alloy, which replaces the pigment to form a special effect, which cannot be replaced by solid paint. The difference in metal composition, the size of the particles, and the characteristics of the resin determine the final effect of the metallic paint.

It can be expressed like this: silver powder is also aluminum powder, and when it is added to the paint as a special pigment, it gets a plain paint. Due to its special glitter effect, it is possible to control the glitter of the metal glitter paint film by changing the shape and size of the aluminum particles.

On the outside of the metallic paint, a layer of varnish is added to protect it.

Plain paint is the first spray of paint, also called primer, and the last spray of solid paint.

The car self-spraying effect is quite average, not durable, and suitable for black or mica silver cars.

1. Performance.

There is a difference between the performance of automotive paint and self-spraying paint, we don't know much about paint, but we can also feel that the durability, gloss, adhesion of self-spraying paint and automotive paint is still a little different, if it is a more conspicuous place of the car, the difference is more obvious. I have used it, because the color is just right, so the color difference is not obvious, the main difference is that if you no longer spray the varnish after spraying the paint, the gloss is not good, and it is not wear-resistant, and it will peel slightly after a long time of exposure.

2. Choose a paint.

There is a color code of the car in the receipt and information of the car (also found on the Internet), use this code to go to the auto parts specialty store (not the general paint shop), you will generally find a spray paint can, ** of course it will be more expensive than the general spray paint, if there are several options, it is recommended to use the best high-end, but never buy a spray paint can without the corresponding code of the car.

3. Choose the climate.

Choose that the weather should not be too hot, not too cold, and the humidity should not be too high, and it should be done as much as possible in the garage room, without strong winds. It is best to spray paint without rain or sun exposure immediately, and let it dry naturally for a few days.

4. Precautions.

Keep away from children; When spraying, the aerosol can must be kept upright and the angle between it and the horizontal plane shall not be less than 45°; Please work in a well-ventilated area; If it splashes into the eyes, rinse immediately with water and then consult a doctor**; If swallowed, vomiting should be triggered immediately and a doctor should be required**; This product is flammable, please store it in a place lower than 40, do not put it in the car, keep away from heat sources and open flames, and it is strictly forbidden to expose to the sun, puncture or burn the can.
