Simply put. Otherwise, a lot of professional knowledge will be displayed … clean the surface of the shell with alcohol first. Dan sprayed your favorite background color with automatic spray paint. When the background color is dry, stick hot wax on it with a brush and draw the pattern you want. Spray another primary color! Remove the wax after drying. Finally, spray a clear surface oil to prevent paint from falling off after rubbing! Wish you success! Thank you.
How to color the plastic model? What do you use to color? How to color?
hello
The first thing to tell you is that the poster color is not a good choice, especially if you don't have a pen.
All paints are divided into oily and waterborne. The so-called oily paints, such as Junshi, Tiangong and Wang Mo paints, can only be diluted with organic solvents, such as banana oil or nitro thinner. Water-based paints such as Xianying can be diluted with water, and they are not afraid of water after painting.
The professional practice is to dilute the paint (oily or aqueous) with thinner and spray it on the surface of the model with a pen.
So for your question, 1 advertising color is not suitable for models to color.
2 professional methods are as above.
If the painting conditions are limited, you can consider industrial canned self-painting, which is available in chemical or building materials stores. Each can is 8- 16 yuan, with slightly thicker paint film and strong adhesion. Pay attention to stay away from the model when spraying, so as not to cause excessive accumulation and tearing of paint film.
How to color a plastic model for 30 points
It is difficult to achieve the effect of a small signboard by coloring. Ordinary models have their own water stickers. The so-called water sticker is a very thin sticker with a transparent background, which is not suitable for things that are often used to play, let alone four-wheel drive vehicles. All I can think of is to make up for them with coloring, but you are also a spray can. I can only talk about how to deal with this painting with a pen. First, it is impossible to achieve the effect by coloring too complicated patterns. Then,
First paint a layer of color, then cover the target part with another layer of color with masking tape, masking liquid and other consumables where it needs to be treated differently, and then remove the covered part after drying to achieve the effect.
Simply put, you cover a place, then color it, and then expose the covered part, so that you can achieve the desired effect. If you need very complicated patterns, you'd better keep waiting for others to come back and forth.

Coloring of plastics
The color matching of plastics is the key to plastic coloring. Only when the colors are well matched can the products with appropriate colors be prepared. In the process of color matching, we should first understand the application requirements of the product and choose the appropriate colorant according to the coloring efficiency of plastic materials. When selecting colors, technicians should strictly check the colors, tinting power, dispersibility, efficiency, processing balance stability, miscibility and cost of available pigments, and then select the pigments to be used and preliminarily determine the dosage. The effect of color selection and collocation depends not only on the professional technical knowledge of technicians, but also on their sound and visual functions. At the same time, it relies on high-tech color matching instruments and equipment. This paper discusses the color scheme and color matching method of plastics. Color matching is one of the important links of coloring. The first choice of color matching is to design a preliminary formula, and then adjust the preliminary formula to make it suitable for mass production and ensure the uniformity and consistency of plastic products. 1. 1 Preliminary Formula Design (1) According to the overall design requirements of plastic products, find samples similar to standard color samples as reference objects. Whether the reference object is selected properly is directly related to the coloring effect. In order to find a better coloring reference, we should accumulate and prepare more colored plastic swatches or plastic pigments for reference, and at the same time organize our own experience and lessons in color selection into corresponding coloring formulas for reference. (2) In the absence of reference, carefully observe and analyze the color, hue and lightness of plastic products (samples), determine the color attributes, determine whether the color used is transparent or opaque, and whether it contains other special pigments (such as fluorescent pigments and metal pigments), and then color it according to Munsell color system. (3) Repeatedly compare the differences with standard color samples and reference objects in hue, brightness, shade, etc. On this basis, the formula of reference colorant was modified and the preliminary formula was drawn up. Or design the required color according to Munsell color system calibration principle, and draw up the preliminary formula. 1.2 Adjust the formula according to the preliminary formula, carry out the physical color test, and compare the prepared color sample with the standard color sample and reference substance to further adjust the color formula. Then, according to the adjusted formula, real samples are prepared for comparison, and then the formula is adjusted and repeated for many times until the hue of the real samples is the same as that of the standard color samples or reaches a satisfactory level closest to the standard color samples. Finally, determine the coloring formula for production. However, in actual production, the selected color is usually different from the color of plastic products, and the reason for these differences is largely the color weighing error. So how to make the color matching accurate? How to keep the color matching consistent in continuous production? The accuracy of color matching is based on the selection of accurate pigments (dyes). The selection of pigment (dye) is based on the understanding of product effect and the observation of samples. The understanding and observation of samples depends on the experience and skills of color matching personnel. At present, many units use instruments to match colors, but some units still use manual visual inspection to match colors. Although the manual visual color matching method is simple, it requires rich experience of visual personnel. When two objects are viewed under the same light source (such as sunlight), their colors may be different. Similarly, for an observer, the colors of two objects may be exactly the same; For another observer, it may be different. We call these two objects allotropes or allotropes, and some of them are allotropes or allotropes. If two objects are required to look the same under any light source, it means that the spectral reflection curves of these two objects must be the same. This color matching is called unconditional color matching or unchangeable color matching. Constant color matching requires the use of the same colorant in the color matching sample. It is impossible to adjust the color of plastic to the same degree of color matching. There are many reasons for this, for example, the dispersion degree of the same pigment in different plastics is different; In a kind of plastic, sometimes it is necessary to decolor or color-adjust to remove other colors in the original plastic; In another plastic, this adjustment may not be necessary. Knowing these situations, we know fairly well in the actual color matching process and don't pursue unchangeable color matching. Since all the colors we match are variable, which condition should be taken as the standard? This requires specific analysis of specific issues. The principle is to observe the color matching by simulating the final use environment of the product as much as possible. If the product is finally used outdoors, you should also choose the color under natural light when matching colors. 2. 1 visual color matching An experienced color matching person must have a clear concept of the colorant he needs before color matching. To master the general law of mixed coloring of colorants, we should also handle it well. ......
What happened to plastic dyeing? What's the difference with plastic dyeing? What is the difference?
The raw materials for dyeing thermoplastics are mostly transparent or milky white, while precision plastic parts often require various colors. Parts in optical instruments need black to prevent light leakage and eliminate stray light, and appearance parts often use different colors according to design needs. Therefore, plastic products need to be dyed before processing, that is, different amounts of dyes are mixed in the plastic in proportion. Thermoplastics can be dyed in three ways:
(1) dry dyeing method: put a certain proportion of dye and plastic particles into a rotating drum, and add 0.0 %~0. 1% zinc stearate or white mineral oil as wetting agent, so that the plastic can easily adhere to the dye, and the plastic and the dye can be completely and evenly mixed through the rotation of the rotating drum.
(2) Extrusion Dyeing Method This method is to mix dyes and plastics by dry dyeing method, and then squeeze them into thin strips by a special extruder and cut them into particles. This method has good color mixing and is helpful for poorly dispersed pigments.
(3) Dry-dense dyeing This method is basically the same as the extrusion dyeing method, except that the proportion of dyes in plastics is more than 10 times higher than usual, and multiple primary color plastics can be added for dilution during injection molding.
