Paint knowledge: grasp the steps and skills of paint color matching, easily mix colors

Core tip: in home decoration, paint is a common material With people's pursuit of life, the general color can't meet people's needs At this time, we need to color the paint Now let's learn about the steps and skills of paint color matching 1 The principle of paint color matching is that the variety of colors is endless and colorful, but there is a certain internal relationship between various colors Each color can be determined by three parameters, that is, hue, lightness and saturation Hue is the characteristic of color which is different from each other It depends on the color composition of the light source and the feeling of each wavelength emitted by the surface of the object to the human eye It can distinguish red, yellow, green, blue and purple 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: home decoration, paint is more commonly used materials With people 's pursuit of life, the general color can no longer meet people' s needs, at this time, we need to color paint Now let's learn about the steps and skills of paint color matching 1 The principle of paint color matching is that the variety of colors is endless and colorful, but there is a certain internal relationship between various colors Each color can be determined by three parameters, that is, hue, lightness and saturation Hue is the feature that colors are different from each other It depends on the color composition of the light source and the feeling of each wavelength emitted by the surface of the object to the human eye It can distinguish red, yellow, green, blue, purple and other features 2、 Paint color matching steps: paint color matching technology mainly includes solid color paint color matching, transparent paint color matching, etc usually before the formulation of color matching formula, it is necessary to analyze according to the paint color card or the color of a certain 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 Then, according to experience, preliminarily draw up the color matching formula, and then through small sample debugging, when color matching, first add the main color Then take the color with strong coloring power as the secondary color, slowly and intermittently add and continuously mix, observe the change of color at any time, sample and wipe, brush, spray or stick on the clean template, after the color is stable, compare with the original template, and master the principle of "from light to deep" in the whole color mixing process It can be seen from the principle of subtraction that if the sample is compared with the standard plate, the method of subtraction or cyanation can be used for over red, the method of subtraction or cyanation can be used for over green, and the method of subtraction or cyanation can be used for over blue, and vice versa, because yellow, blue, purple and blue, red and green are complementary colors, but the pigment This kind of mixing will lead to the decrease of lightness You can use black and white to adjust the lightness of the mixed color 3、 Some auxiliary agents, such as varnish, curing agent, desiccant and so on, can be added properly in the process of color matching In winter, desiccant should be added into the container before color matching to avoid affecting the color Paint with the same properties shall be selected for the preparation of multi-color paint, and the solvent system shall also be soluble, otherwise, the paint quality will be affected, and serious delamination, gelation and other phenomena will occur When preparing grey, green and other multi-color paints, a variety of pigments are required Due to different oil properties and densities of various pigments, "floating color" and "blooming" often occur At this time, a small amount of surfactant, leveling agent and anti floating agent can be added as appropriate to solve the problem The addition amount is generally 0.1% - 1% Home of coatings focuses on coatings, paint coatings, coating technology, news and information of fire retardant coatings, coatings, coating technology, decoration knowledge and decoration renderings of fire retardant coatings,
