What are the color matching skills of paint toner?

How can you draw without paint? There are many colors of paint. At first, there were only monotonous colors. Now people have blended many colors. The color of the pigment must be mixed with the toner. Mixing colors is not as simple as people think. First of all, people need raw materials of color. Therefore, the color matching method is very important, and the paint toner is different from the general color matching method. Bian Xiao will show you the color matching technology of paint toner.

Color matching skills of paint toner

1, color matching needs to be cautious. Generally, samples should be taken first, and the amount of color matching paint can be preliminarily obtained, and then it can be prepared according to the sample results.

Overall situation. First, adjust the secondary color and secondary color in a small container.

2. First add the main color (the color with large dosage and low tinting power), then slowly and intermittently add the dark color (or tinting) with high tinting power, constantly stir and observe the color change at any time.

3, "from shallow to deep", especially when adding pigments with strong coloring power, don't overdo it.

4. When matching colors, the colors of paint and dry film will be slightly different. The colors of various paints are generally light when wet, and dark when dry. Therefore, if the sample is a dry sample, the color matching paint needs to be dried before it can be compared. If the sample is wet, you can drop a drop of the sample in the color-matching paint to see if the two colors are the same.

5. It is necessary to know in advance the floating degree of primary colors and the changes of coating materials in colorful coatings, especially amino coatings and perchloroethylene coatings.

6. When preparing colorful coatings, the coatings with the same selectivity should be mixed with each other, and the solvent system should also be mutually soluble. Otherwise, due to the poor miscibility of the coating, the quality will be affected, and even delamination, precipitation or gelation will occur, so it cannot be used.

7. Because colors often have different color heads, if they are paired with positive green, they are generally yellow with green heads and blue with yellow heads; When purple and red are matched, blue with red head and red with blue head should be adopted; When matching orange, use red with yellow head and yellow with red head.

8. Pay attention to the color of auxiliary materials such as drier, curing agent and diluent, so as not to affect the color.

9. When preparing multi-color paints such as gray and green, it is easy to appear "floating color" and "halo color" because of the different densities and oil absorption of various pigments. At this time, a small amount of surfactant, leveling agent and anti-floating agent can be added as appropriate to solve the problem. Add 0. 1% silicone oil as usual for prevention. Various surfactants produced by foreign companies need to be used in different solvent systems, and the addition amount is generally 0. 1% ~ 1%. (10) Using the slightly transparent characteristics of the paint film and choosing a suitable background color, the color of the top coat can be more vivid than the original paint. This is a color produced by the superposition of background color and primary color according to the principle of natural light reflection and absorption, which is called "transparent color" in coating engineering. For example, yellow primer can make red more vivid, gray primer can make red more vivid, positive blue primer can make black more vivid, and water blue primer can make white more clean and innocent.

After mastering the skills, you can easily match colors and freely use toners to mix the colors you want. There are many matters needing attention in the process of mixing paint toner, which need people's special attention. If you are not sure whether the mixed color is what people want, try to mix it with a little toner first, and then mix it in large quantities with the right color. The quality of paint toner will also affect its color, so we try to choose high-quality paint toner.
