Color matching and method of pigment color in the paint production plant

color colorcolor preparationcolor color preparation of the wits: the use of a variety of color materials for color matching, to the standard color card or standard swatch as the benchmark, first of all to find out the color to be formulated on the color card name, and then find out the standard color card consistent with the basic color of the blend color, to determine the color of the main color and auxiliary color, color clarity and puritySeveral color tints need to be leveled to clarify the order in which the primary and secondary colors are added, the proportion (i.eratio) and the amount requiredThen choose to use performance and color (i.ecoloring force) are better color, ready to provision equipment and tools, you can be color blendingWhen the coating operator uses the color material to color, when the color coating is too late, the main color phase that has been formulated by the primary color coating can be usedThe so-called main color, is two or more of the primary color paint to blend out the basic tone, and then use pigment color paste to adjust the hue, clarity and purityPaint production plant pigment color is the formulation of paint components of the resin, oil, pigments (according to the proportion of color matching), drying agent and organic solvent mixing, first grinding and dissolving after refining into a certain color of finished coatingcolor matching method
according to the basic knowledge of color theory, color matching method can be divided into color and color reduction method of two color matching methods for color matching, as described below:(1) color matching method: a variety of different wavelengths of color light on the object, a variety of objects reflected out of the color wavelength is not the same, the color seen by the human eye is a certain wavelength range of color can be rendered in the color range, such as blue is in the wavelength range of 450-5000mThis blue color, clarity and purity are standardIf two different colors of light, they are irradiated at the same point (on the white curtain) then reflect (refracted) the reflected (refraction) of the color light stimulates the human eye, the color of the color visible to the eyes of the people is more bright and bright than the single color of the human eye visible color light (color)This means that the addition of colors results in a blend of brighter and brighter colorsAdd up to color to get more different bright blendcolorsA method of adding colors to get more mixed colors with different brightness is called the color-adding method(2) color-reducing: there are six main colors in the spectrum of sunlight, namely red, orange, yellow, green, blue, and purpleFrom the knowledge of color theory, it can be seen that the pigment in the object can absorb certain color light, but reflect the color light can not be absorbed, thus presenting the color given to the object by the reflected color light (but also a color within a certain wavelength range of color beam can present a color), the color material is also the same, when the sun shines on the blue pigment, blue pigment absorbs all the orange light, most of the red and yellow lightYellow pigments absorb all the purple light, the blue light, and the majority of the red light absorbed by the blue light, leaving a small amount of the red light, so the yellow and blue pigments mix to absorb the other color light and the rest is only green lightSo green is a blend of colors in which other colors are absorbedThat is, yellow and blue mixed color, it is concluded that several color phase shimimumation to get a composite color, is to absorb the other colors used to blend this color, and reduce those color originally very bright color, brightness and color, that is, to varying degrees to reduce the color, clarity and purityThis color matching method is called the color-despering method
