What is Automotive Painting? When is car painting used?

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.

The forms are ordinary paint, metallic paint, and pearlescent paint. Automobile painting process: putty scraping, grinding, painting, etc.

1.When the paint surface is seriously aged and cannot be solved by polishing and reduction process; 2.When the paint surface is eroded by the lens effect and the light is seriously lost; 3.

When the oxide layer of the paint surface is thick, local corrosion occurs, and it cannot be polished and reduced; 4.When the paint surface is deeply scratched and cannot be removed by polishing; 5.When the paint surface is partially or partially damaged.

2. What are the common problems in the process of automobile painting?

1.Sag. When the surface paint flows downward due to excessive spraying, it is necessary to polish off the sagging part at a specific position and re-enter the spray booth for spraying.

2.Lacquer thin. Due to too little painting, the surface does not meet the thickness requirements and causes color difference, which must be re-sprayed to ensure that the process requirements are met.

3.Wet spots. This phenomenon is the contour of the surface of the paint layer along the contaminated area of the underlying layer, with many uneven pits. The remedy is to remove the paint layer from the affected area and re-paint it in strict accordance with the process requirements.

4.Water spots. This condition is characterized by etched spots on horizontal surface areas such as the hood, roof and trunk lid, most noticeably on the dark surface of the stone.

In order to prevent the occurrence of water spots, coatings with excellent water resistance can be selected according to the climatic characteristics of the area where the car is used before spraying, and silane additives can be added if necessary. After the appearance of water spots, the surface of the paint layer can be polished with coarse wax or polish, and if the condition is severe, the affected area should be sanded with sandpaper and repainted.

Every one of our car owners in the process of using the car will definitely encounter the car is scratched, or there are various traffic accidents caused by the deformation of the car paint situation, once such a situation occurs, if you do not want to let your car appearance be affected, you must need to paint the whole car. If there are only some slight scratches, or there is some small paint loss in the car, it may not be necessary to paint the whole car at this time, only local treatment is required.

1. Under what circumstances do you need to paint the whole car?

Not long ago, there were some cracks in the paint on Mr. Gao's car, because Mr. Gao's car had been spray-painted before, but the quality of the previous paint was very unsatisfactory, and cracks appeared in many places. For this reason, Mr. Gao decided to paint the whole car again. In fact, the situation of Mr. Gao's car does need to be painted throughout the car.

In addition, when the paint surface of the car has fallen off in a large area, or when rust has occurred, it is also necessary to spray the whole car with paint.

The car paint is sprayed all over the car.

2. How much does it cost to paint the whole car?

If you need to carry out a comprehensive painting treatment on the car, due to the different paints used, plus different places, the price of this treatment is often different, generally speaking, those ordinary paints, about 1000 yuan, and those *** some paints, may need two or three thousand yuan, or higher prices.

Summary. In fact, if you want to carry out a comprehensive painting treatment for the whole car, the most important thing is to choose those more professional places to complete this work, because if it is not professional, it is possible that the concocted paint will have color difference and affect the overall painting effect.

As the outer coat of the car, the automobile paint coating mainly has the following functions. (1) Protective effect: As an outdoor transportation tool, the automobile has been eroded by various corrosive media in the atmosphere for a long time, such as moisture, oxygen, industrial atmosphere, sulfur dioxide, carbon dioxide, nitrogen dioxide, etc. in the atmosphere.

Automobile paint forms a continuous film that is firmly attached on the automobile, can avoid the chemical or electrochemical reaction between its surface and the surrounding medium, and prevents or delays the occurrence and development of the phenomenon of damage to the automobile. (2) decorative effect car surface is coated with a variety of brightly colored paints, appears beautiful and generous, bright and comfortable, gives people a feeling of beauty, also highlights the personality of the vehicle.

A plump paint film can also improve the grade of the car. (3) the color of the logo effect car paint can be used as the type and function of the car signs, such as postal car is green, ambulance is generally white and so on. Other FunctionsSome automotive coatings can improve the comfort and tightness of the car and prevent noise from vibration.

The first is to reduce the residual value of second-hand goods, and the second is that no matter how good the material is, no matter how good the technical level is, it cannot meet the standard of the original paint. The disadvantages are:

Chromatic differences are unavoidable, and what is unacceptable is that it is obviously a small piece, but it is necessary to spray as a whole to cover up the color difference.

The repair paint can not reach the hardness of the original car paint at all, because many repair shops will not use the paint room in order to reduce costs, even if the real paint is baked, it cannot reach the temperature of the original car paint, so it is normal to crack and peel after two years.

After touching up the paint, due to the thickness and quality of the putty, a small bump will fall off a large piece.

If the bottom sill is not deformed by collision, it is not recommended to go to the sheet metal paint, because the steel plate will oxidize after overheating, and it will inevitably rust and rot in the humid environment in the rainy season.

If the front and rear bumpers are partially damaged by impact, it is recommended that you replace them with new ones, and if you repaint, you can repair the paint on the original paint surface for the second time, and the firmness is very poor, and it is difficult to avoid paint loss in the future.

If you do want to repair the small scratch, it is recommended to pay for it, because the insurance will increase the premium in the second year.

Summer is the best, did you break down your own car or what? Here I will tell you specifically: the temperature is relatively high in summer, because the paint is in a liquid state, and a layer of bright light on the surface of the paint is no different from water, compared to water, it is thicker After adjustment, it can be added to the spray gun to spray paint operations, if it is winter, because it is a liquid state, it dries slowly, the most prominent, and the most common phenomenon, that is, the "flow point" is the same as **tears, ugly, serious may have to be reworked In summer, it dries faster, So there is no such phenomenon, which is the main thing.

When does the car have to be painted?

1.When the paint surface is seriously aged and cannot be solved by polishing and reduction process; 2.When the paint surface is eroded by the lens effect and the light is seriously lost; 3.

When the oxide layer of the paint surface is thick, local corrosion occurs, and it cannot be polished and reduced; 4.When the paint surface is deeply scratched and cannot be removed by polishing; 5.When the paint surface is partially or partially damaged.

Small scratches and not very serious.

421 2017-12-16 Is there a difference between the 4S painting and the original painting? 74 2013-09-21 4s Hello everyone! Today I will talk to you about the problem of automobile sheet metal painting.

There are always bumps and bumps in the process of driving, and it is inevitable that there will be some places, especially the iron sheet of the body, to wipe off a piece or lose the paint. Just the day before yesterday, the little car saw a scene on the road where a sedan rode to the green belt during a U-turn, and the driver....

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.

Hello 1, car primer is also called anti-rust primer, that is, the paint for the primer, which is generally directly applied to the surface of the object or coated on the surface of putty. Its function is to prevent oxidation and corrosion of the metal surface, and enhance the adhesion of the metal surface to putty or intermediate coat and topcoat.

2. A good anti-rust primer is the premise of durability and beauty of the topcoat. If the anti-rust primer is not good, the appearance of the topcoat will be affected, and even cracks or peeling will appear.

The above two points are very important, spraying anti-rust primer is the basis of paint, the foundation is not laid, it is difficult to do a good job in the follow-up, so the anti-rust primer is very important, and you need to spray anti-rust primer to do spray paint.

Answer: The main function of car painting is to prevent metal rust and corrosion, and another reason is for aesthetics, which is equivalent to wearing a beautiful dress.

Automobile paint is divided into original car paint and car refinish paint according to different coating objects

1.The original car paint is generally coated with at least five layers of paint film, which are primer (mostly electrophoretic paint and has anti-rust function), middle paint layer (the purpose is to cover the electrophoretic paint layer), primer paint (also known as color paint), topcoat (the body color we see), and clear coat (colorless and transparent mainly used to protect the topcoat).

2.The biggest difference between the repair paint, which is the paint we go to the general repair shop and the 4S shop every day, and the original car paint is that there is no electrophoretic paint layer, and some unscrupulous car repair shops even save the anti-rust paint layer.

Automobile paints are divided into domestic paints and imported paints according to different origins

1.Domestic paint: The general repair shop will not tell you the brand of domestic paint in the process of painting, in fact, domestic paint also has advantages and disadvantages, but most of the domestic paint ** is cheaper than imported paint, which dilutes people's understanding of domestic paint brands.

2.Imported paint: We focus on imported paint, the current high-end models on the market are imported paint, there are two main types of paint parrots imported from Germany, Ash, Schbikuai, the United States imported paint ppg, DuPont, Valspar.

Imported paint is much more expensive than domestic paint, but the quality is excellent.

Auto paints are divided into oil-based paints and water-based paints according to the different properties of the paints

1.Oil-based paint: commonly found in low-end models, models below 200,000 are basically oil-based paint, and water-based paint is different in that oil-based paint is insoluble in water and needs to be diluted with Tianna water (also known as banana water or rosin perfume).

The main component of Tianna water is xylene, which is extremely volatile, flammable, explosive and toxic, and belongs to dangerous goods. It will cause great damage to the environment and the human body (Shenzhen will ban the use of oil-based paint at the end of the year).

2.Water-based paint: common in high-end models, and oil-based paint is different in that there is no need to use Tianna water as a thinner, the paint dries faster, and the direct use of water can not cause harm to the environment and the human body.

However, the cost is more expensive than oil-based paint, and at the same time, it also has higher requirements for the spraying environment and paint baking room, and the input cost is high.
