The colorful colors have always been an important element in the world. The paint in the decoration is no exception. The paint can also be used to reconcile various colors. It is mainly used for decoration and decoration, how to match the paint, and how the paint palette is. Friends may be interested, the following small series to introduce you!
How to paint color
1, pay attention to the principle of paint color matching
Do not use more than three types of color paint for general color. In the basic color, basically add white, you can get different colors of saturation (that is, different shades of color). On the basis of the primary colors, add black, you can get different colors (that is, different colors) with red, The three colors of yellow and blue are mixed in a certain ratio to obtain different intermediate colors (ie, colors with different tones).
There are two ways to match colors:
One is a color that is formulated according to text or verbal requirements, which is convenient and easy for the oiler. However, color selection is very important. If the color is not suitable, the color matching effect will not be ideal. For example, in the green, any yellow and blue can be adjusted to medium green, but only in the case of better yellow and blue purity, the green is more pure and vivid.
The other is to be deployed according to the requirements of the model. The requirements are high and the technology is strong. It is not easy for ordinary oil workers to do. Mainly relying on practical experience, and with the color swatches to compare, to identify which color of the excellent board is composed of several kinds of monochrome, the proportion of each color is roughly, and then use the same variety of paint for trial matching. After approval by the design and construction unit, and using the same or similar coating method as the sample, the same color as the sample is applied.
2. The consistency of the paint consistency may cause the consistency of the paint to be too large due to storage or climatic reasons. The appropriate amount of thinner should be added to the paint to reduce the consistency to meet the construction requirements. The amount of diluent should not exceed 20% of the weight of the coating. Exceeding it will reduce the film properties. The thinner must be used in conjunction with the coating and should not be abused to avoid quality accidents. For example, shellac must use ethanol, while nitrocellulose paint should use banana water.
3, the coloring agent is used for the blending of colorants on the wood surface is mainly the matching of water color, wine color and oil color.
Speaking of furniture paint coloring, we must first understand some of the relevant knowledge of color, the principle of color three primary colors is universal. We all know that the competition in the furniture industry is becoming more and more fierce. In addition to ensuring the novelty of quality and style, there is also a point to ensure the diversity of the color of furniture. This will be more competitive.
First, the method of furniture paint coloring
We said the color in the front, now we talk about the matching of the paint, the precautions; people with color blindness can't mix the paint and have to match the color under the natural light. The color of the paint should be according to the color of the sample. Try the sample first. For the sample board, determine the color paint in several colors, and then put these color paints in the tank, first weigh the hair, then use it to color, after the color is finished, weigh it once, this weighs once. The difference is to participate in the color matching of various color paints. As a reference when blending large samples, in the process of color matching, the color paints that participate in the color matching should be slowly added, and the stirring should be kept at any time to avoid making it too much. From shallow to deep until registration.
If the consistency of the paint is too large due to storage or climatic reasons, the coating should be mixed with an appropriate amount of thinner to reduce the consistency to meet the construction requirements. The amount of diluent should not exceed 20% of the weight of the coating. Exceeding it will reduce the film properties. The thinner must be used in conjunction with the coating and should not be abused to avoid quality accidents. For example, shellac must use ethanol, while nitrocellulose paint should use banana water.
Pay attention to the color of furniture paint:
1. When blending the multi-color paint, select the paint with the same performance to match.
2. When matching colors, first select the main color, and estimate the proportion of each color, then mix it from shallow to deep, and stir the country and Canada.
3. Pay attention to what auxiliary materials should be added during the preparation process, add the agent and thinner. Curing agent and so on.
4. When blending gray and green paint, it is made of medium color, which may occur (floating color). At this time, you can add a little trace of silicone oil to prevent, {1:1000} 5. To match the color under the sun, the color of the blend should generally be slightly lighter than the original.
Second, furniture paint coloring skills
1. Care should be taken when grading. Generally, try the sample first, and initially determine the quantity of the color matching paint, and then prepare the large sample according to the sample result. First adjust the secondary and secondary colors in a small container.
2. First add the main color (the color is large in the color matching, the coloring power is small), then add the dark color (or color matching) with large dyeing force slowly and intermittently, and constantly stir, and observe the color change at any time.
3, "from shallow to deep", especially when adding pigments with strong tinting strength, avoid excessive.
4. In the color matching, there will be slight differences in the color of the coating film after drying and drying. The color of each paint is generally shallow when wet, and the color is deepened when the paint is dry. Therefore, if the sample is a dry sample, the color paint needs to be dried and then compared for color measurement; if the sample is a wet sample, the sample can be dropped into the color paint to see if the two colors are the same.
5, in advance should understand the floating color of the primary color in the complex paint and the changes in the paint, especially the amino paint and perchloroethylene paint, need to pay more attention.
6. When blending multi-color coatings, the coatings with the same properties should be selected and the solvent system should be mutually soluble. Otherwise, the miscibility of the coatings is not good, which will affect the quality, and even delamination, precipitation or gelation may not be used.
7, because the color often comes with a variety of different color heads, if the matching green, generally with a green head with yellow and yellow with a yellow head; with purple, should use a red head with blue and blue with a red head When equipped with orange, red with yellow head and yellow with red head should be used.
8. Pay attention to the auxiliary materials, such as drier, curing agent, thinner, etc., in the process of blending colors, so as not to affect the color.
9. When blending gray, green and other complex paints, due to the preparation of various pigments, the density and oil absorption of the pigments are different, it is likely that "floating color" and "floating" may occur. At this time, a slight amount of surface may be added as appropriate. Active agent or leveling agent, anti-floating agent to solve. As usual, 0.1% of silicone oil is added to prevent and control. The various surfactants produced by foreign companies need to distinguish which solvent system is used, and the amount of addition is generally 0.1% to 1%. (10) The color paint film is slightly transparent, and the suitable base color can make the color of the top paint more vivid than the original paint. This is based on the principle of natural light reflection absorption, and the background color is superimposed with the original color. One color, the paint project is called "transparent color." For example, a yellow primer can make red more vivid, a gray primer can make red more red, a blue primer can make black blacker, and a water blue primer makes white whiter and clearer.
