How long does it take to learn car paint toning?

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.

No matter what color paint is, its pigment will fade in the sun. In fact, not only paint, but anything with color can fade in the sun. At this time, the additives added to the paint are very important.

For example, light stabilizers, such as antioxidants, etc. Unfortunately, good additives are expensive and expensive. Many times, the quality of the additives determines how the paint feels.

One would surely think that some kind of paint that starts to fade significantly after 2 years is worse than a paint that is shiny as new after 5 years. But in reality, there is no paint that does not fade. In many cases, the factory is more concerned about:

Fade evenly. Try not to make color differences in different parts of the car.

How long it depends on yourself, and the more hard work you have, the faster you learn.

Hello, it depends on where you go to learn, and it may take a year or two for the outside store to learn dry goods. It is recommended that you find a professional auto repair school to study, where there are many practical classes, and you can learn it in about a month or two.

Coloring is a friend who does not have textbooks, and the textbooks are explored by themselves, explained by the master, and then accumulated time. Let me tell you about my experience in learning color grading, you can refer to the colorists know the most basic color composition: red, yellow, blue.

These three colors are called primary colors, and the colors that are blended in different proportions of these three colors are called compound colors. Each color can be determined using three parameters: hue, lightness, and saturation. Hue is the characteristic of colors that distinguish them from each other, and the chromatographic composition of the Liangding light source and the perception of the wavelength reflected by the surface of the object can distinguish red, yellow, blue, green, violet and other characteristics.

Luminosity, known as luminance, is a characteristic value that indicates a change in the sensitivity of an object. Saturation, also known as chroma, is a characteristic value that indicates the intensity of color on the surface of an object. Add white to the color palette to dilute the primary or compound colors to get different colors of "saturation and delay";Add different amounts of black to get different colors of "brightness".

There is no textbook, but you can look for a textbook for drawing, because you have to be sensitive to color before you can quickly and accurately tune it.

Hello, it's not difficult, it is recommended that you find a professional auto repair school to learn, there are many practical classes, and it is easier to learn more hands-on operations.

You can go to the school to study, you can first look at the teaching environment and teaching facilities.

Not necessarily, some people are very smart and may only take a few months to master, while others are not very sensitive to color and may take several years to get it. Of course, if you want to learn well, it is definitely impossible to learn without three or five years.

Automobile paint mixing is a technical activity, especially when repairing paint, it can reflect the hail excavation, because the original car paint is sprayed under aseptic conditions, and then the car can not be the same as the original car paint when the car is scratched and repaired, and the car paint can only be close to the color of the original paint through paint mixing.

Friends who have touched up paint on this point should know that some repair shops can not see it after repairing the paint, and some repair shops have repaired the paint color and the car itself The difference between the paint is very large, so if you want to learn to mix paint well, if you want to learn fine, then the time required is definitely not a few months to do, it takes time and experience to accumulate.

Although there are a variety of colors of paint, due to the different design and decoration styles during construction, many colors can not meet the needs of use, so we need to configure it ourselves. So how to mix paint, what are the tips for paint mixing? Don't worry, I'll introduce some of the noodles to you, and those who don't know should take a serious look!

1. Paint tinting skills 1.

Debugging the sample is a necessary process before we match the color, first determine how many colors of the paint sample contains the secondary color paint, calculate the color types involved in the color matching, and then adjust the secondary color and secondary color in the small container.

2. Paint tinting skills two.

The main color paint is the color paint with a large amount in use, but the coloring amount is small, add the secondary color paint with strong color strength in the main color paint, stir evenly, compare the sample and the color plate, from light to dark, check at any time until the satisfactory effect is achieved. For example, with beige paint, you should first add an appropriate amount of white paint, slowly add yellow paint, and keep stirring until you reach the desired color.

3. Paint tinting skills three.

The color of the paint is light when it is toned, but the color will become relatively dark after drying, so the color of the wet paint should be slightly lighter than the color on the sample, and it is necessary to grasp the floating and other properties of a primary color in the color matching in advance, especially amino coatings and perchloroethylene coatings.

4. Paint tinting skills four.

Add some auxiliaries appropriately, such as varnish, curing agent, desiccant, etc., and add desiccant to the container in winter before starting to match the color, so as not to affect the tone.

The paint of the compound color paint needs to choose the paint with the same nature, and the solvent system should also be miscible, otherwise the quality of the paint will be affected, and there will be delamination and gelatinization in serious cases.

5. Paint tinting skills five.

Colors generally come with different color heads, and so on according to the following color matching principle:

When matching green, yellow with a green head and blue with a yellow head are generally used.

When paired with purple red, blue with a red head and red with a blue head should be used.

When paired with orange, use red with a yellow head and yellow with a red head.

When blending gray, green and other compound color paint, a variety of pigments are needed, the oiliness and density of various pigments are different, and there are often phenomena such as "floating color" and "flowering", at this time, a trace amount of surfactant or leveling agent and anti-floating agent can be added as appropriate to solve, and the amount of addition is generally in.

Paint tinting is a technical job, not a day or two can be learned, it is best to find a furniture factory to start with the basic workers, see more, do more, slowly ponder, find a way, and slowly get started.

Hello! There are no shortcuts to tinting techniques, and if you want to learn how to tone automotive paints, you have to start with the basics of color.

The three primary colors of pigment color are yellow, magenta, and cyan. In paint, with black and white, you can bring up any color.

A color contains three elements, namely hue, lightness, and purity.

When you want to tune into a certain model color, you first have to judge the hue of the color, when you tune out the hue of the color, then you have to observe the brightness of the color, if it is too dark, you add white, if it is too bright, you add black. Finally, you need to compare the purity of this color with the sample color. If the color is not bright enough, you want to add the pure color of the color, and if the color is too bright, you need to add the brightness value of the color gray.

In short, color adjustment is not an easy task. However, it is not difficult if it will, but it will not be difficult if it is difficult. As long as you continue to study and practice, there is nothing difficult in the world, but I am afraid of people with hearts! I'm sure you'll become a master of color grading.

Hello, you can find a professional school to learn, the professional school has three points of theory and seven points of practice, listen carefully in class, ask if you don't understand, and it is easy to learn if you get started.

Go to a professional place, find a master, and concentrate on learning.
