Coating technology: basis of powder coating color matching

Core tip: in recent years, with the continuous expansion of the application field of high-performance powder coating, different coloring styles also show a trend of diversification, and decorate a good space for people's life Powder coating formulators should select colors according to different environment, different conditions, different coating brands and requirements, and use a variety of methods To be consistent with the sample to achieve a more perfect color The color matching principle of powder coating is the same as that of common coating The color is a kind of visual angle nerve feeling after the human eye is stimulated by the radiation energy of certain wavelength and intensity of the object Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: in recent years, with the continuous expansion of the application field of high-performance powder paint, different color styles are also diversified, and people's lives are decorated with beautiful space Powder paint formulators are engaged in color design or pigment When matching, color selection should be carried out according to different environment, different conditions, different paint brands and requirements, and various methods and means should be used to achieve consistency with the sample and a more perfect color The color matching principle of powder coating is the same as that of common coating Color is a kind of visual angle nerve feeling that human eye is stimulated by radiation energy of certain wavelength and intensity Although the colors vary greatly, the most basic colors are only red, yellow and blue, which are commonly called three primary colors The two primary colors are mixed into two secondary colors (intermediate colors) and two secondary colors It is mixed with the primary colors to form a multi color, as shown in the figure: when the three primary colors of red, yellow and blue are mixed together, they will become black As a toner of powder coating, it is necessary to master these basic knowledge Generally, a pigment has three parameters of hue, saturation and lightness to determine, also known as the three elements of color Hue refers to the color difference among different colors, such as red, yellow, blue, etc., which determines the spectral composition of the light source and the feeling of the proportion of various wavelengths of radiation reflected (or transmitted) on the surface of the object to the human eye Lightness (also known as brightness), refers to the difference between the light and shade of the color, which is the brightness feeling of the human eye on the object Generally, the hand perspective perception and the influence of past experience, the higher the reflectivity of the object to the light, the higher its brightness Saturation (also called purity), refers to the saturation degree of color, sometimes called chromaticity, which is the color purity displayed on the basis of hue The monochromatic light of visible light is the most saturated color When these pigments are mixed with white light, the more unsaturated they are, the worse the reflection selectivity of light wave is, and the stronger the selectivity of light wave is, the more saturated they are Single color is pure color without adding other colors, and other colors are added to change into intermediate color or polychrome When two painted workpieces of the same color are illuminated by different lights or sunlight, the two objects show different colors and colored lights This is the nature of brightness Colors of a certain color have different strengths and weaknesses, which is the difference in saturation The three elements of color can be used to distinguish the difference of colored powder coating, that is, only when the three characteristic values of hue, brightness and saturation of two colors are the same, the two colors can be exactly the same If one of the parameters is not equal, the two colors are not the same With the information of colorimetric conditions and color difference range, we have a full grasp of the performance of the pigment Due to the limitations of instrument color matching, the final effect of instrument color matching depends on visual inspection, so artificial color matching is still the main method of color matching in the near future Home of coatings is specialized in
