Coating technology: basic knowledge of color matching

Core tip: the mixing color matching of the coating follows a principle of subtraction The three primary colors are yellow, green and purple, and their complementary colors are blue, red and green The so-called complementary color is that two kinds of color light are mixed to get white color light according to a certain proportion The complementary color of red is cyan, the complementary color of yellow is blue, and the complementary color of green is purple The results of subtractive mixing are summarized as follows: Yellow = white blue Purple = white green Cyan = white red Yellow + Purple = white blue green = red Yellow + cyan = white blue red Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: the mixing and matching of paint follows a principle of subtraction The three primary colors are yellow, green and purple, and their complementary colors are blue, red and green The so-called complementary color is that two kinds of color light are mixed to get white color light according to a certain proportion The complementary color of red is cyan, the complementary color of yellow is blue, and the complementary color of green is purple The results of subtractive mixing are summarized as follows: Yellow = white blue purple = white green cyan = white red yellow + Purple = white blue green = Red Yellow + cyan = white blue red = green purple + cyan = white green red = Blue Yellow + Purple + cyan = white blue green red = black Add the relationship in turn, after mixing the color, its lightness is reduced The color mixing technology of paint mainly includes solid color paint and transparent paint Usually, before the color mixing formula is drawn up, it needs to be analyzed according to the color template or the color of a real object First of all, understand the color range, which is composed of several colors, which is the main color, which is the secondary color, how the relationship between color and color, and how much each proportion is about; secondly, according to experience, preliminarily draw up the color matching formula, and then after small sample debugging, when color mixing, first add the main color, then take the color with strong coloring power as the secondary, slowly and intermittently add and constantly stir To observe the change of color at any time, sample, brush, spray or stick on the clean sample plate, after the color is stable, compare with the original sample plate, and master the principle of "from light to deep" in the whole color mixing process Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
