In the field of metal surface color technology, aluminum profile is one of the most easily colored metals. In recent decades, with the application of aluminum profile in light industry, architecture and other aspects, the decorative requirements of aluminum profile surface are also higher and higher. The most commonly used decoration technology after aluminum profile oxidation is Aluminum profile Its purpose is to provide the surface of aluminum profile with colorful, light resistant, weather resistant and more exquisite surface decoration effect;


 Light duty, industrial aluminum profiles

According to the different distribution of coloring materials and pigment bodies in the oxidation film, the anodizing of aluminum profiles can be divided into three types: Dye Adsorption coloring (also known as chemical dyeing), electrolytic coloring and natural coloring or electrodeposition coloring. The mechanism of these three coloring methods is different, and the deposition part of chromophore in the oxidation film is different The results show that the chromophore is deposited on the upper part of the pore space of the oxide film by adsorption in dye adsorption method; the metal chromophore is deposited at the bottom of the pore of the porous film during electrolytic coloring; the electrolytic coloring method is much more complicated than the first two methods. According to the difference of electrolyte and aluminum profile, the chromophore is in the sandwich wall of the porous layer or the colloidal particles of the chromophore are in the sandwich wall of the porous layer In this chapter, we will discuss these three coloring methods;

 

Adsorption dyeing

The anodizing film of aluminum profile which needs to be dyed should be colorless and transparent, especially when it is dyed with light color. Among the common anodizing processes, sulfuric acid anodizing film has the best transparency, which is the most commonly used manufacturing method of adsorption dyeing oxidation film;

 

According to the different materials used, the adsorption dyeing method can be divided into inorganic dyeing method and organic dyeing method;

 

According to different requirements, dyeing methods can be divided into single dyeing and multiple dyeing; single dyeing is to obtain a single color effect to meet the requirements of product design to highlight the part of the logo or to provide a color appearance for the whole product; multiple dyeing can be divided into single dyeing and multiple dyeing Aluminum profile The product appearance provides a sense of hierarchy and dynamic composed of multi colors, and also provides color difference for product identification to facilitate identification. However, one problem should be noted here: Although the natural color of aluminum profiles also provides a hue, it does not belong to the color contrast formed by dyeing technology, but belongs to the primary color of profiles;

 

The first section: the basic knowledge of color

 

one Basic knowledge

Theoretically speaking, color can be divided into two categories: achromatic and colored;

(1) Achromatic system: achromatic refers to white, black and various shades of gray mixed by two basic colors of white and black; achromatic system can be arranged into white to light gray, medium gray, dark gray to black according to certain change rules, which is called black and white series in chromatics; the change from white to black in black and white series can be represented by a vertical axis, and one end is called black and white series White, one end is black, there are various transition gray; pure white is an ideal fully reflected object, pure black is an ideal fully absorbed object; however, there is no pure white or pure black object in real life, zinc white and lead white used in pigment can only approach pure white, coal black can only approach pure black; there is only one basic property of color without color system - lightness; they do not have the properties of hue and purity, that is to say, their hue and purity are equal to zero in theory; the lightness of color can be expressed by black and white, the closer to white, the higher the lightness; the closer to black, the lower the lightness; as pigments, black and white can adjust the reflectivity of aluminum profiles to improve or reduce the brightness of aluminum profiles;

 

(2) There are color system (hereinafter referred to as color system). The color system refers to red, orange, yellow, green, green, blue, purple and other colors; different lightness and purity of red, orange, yellow, green, green, blue, purple tones belong to the color system; color is determined by the wavelength and amplitude of light, the wavelength determines the hue, and the amplitude determines the hue; the color with color system has three basic characteristics: hue, purity, green, green, blue, and purple In chromatics, it is also called the three elements of color or the three attributes of color;

 

① Hue: hue is the biggest feature of the color system; the so-called hue refers to the name of a certain color, such as rose red, orange, lemon yellow, cobalt blue, wine red, emerald green and so on. In terms of optical physics, all kinds of hues are determined by the spectral composition of the light emitted into the human eye; for monochromatic light, the characteristics of the hue completely depend on the light For mixed color light, it depends on the relative amount of light of various wavelengths; Aluminum profile The color is determined by the spectral composition of the light source and the reflection characteristics of the profile surface;

 

② Purity (chroma, saturation): the purity of a color refers to the purity of the color, which indicates the proportion of colored components in the color; the larger the proportion of color components, the higher the purity of color; the smaller the proportion of color components, the lower the purity of color; all kinds of monochromatic light of visible spectrum is the purest color, which is the ultimate purity; when a color is mixed with black, black, and other color components, the purity of color is lower When white or other colors are added, the purity changes; when the mixed color reaches a large proportion, in the eyes, the original color will lose its original luster and become the blended color; of course, this does not mean that there is no original pigment in the blended color, but a large number of other colors are mixed to make the original pigment assimilated, and the human eye has already Can't feel it;

 

The color purity of colored profile is related to the surface structure of aluminum profile; if the profile surface is rough, its diffuse reflection will reduce the color purity; if the aluminum profile surface is smooth, then the total reflection will make the color more bright; for the surface treatment of aluminum profile, the polished surface color is more bright, while the sandblasted or matte surface color is softer;

 

③ Lightness: the lightness refers to the brightness of color; various colored objects produce the change of light and shade due to the difference of the amount of reflected light; the lightness of color has two situations: one is the same color with different lightness; the same color appears bright under strong light, but appears gray and dim under weak light; the same color can produce various kinds of color after adding black or white The second is the different lightness of different colors, each pure color has its corresponding lightness, yellow has the highest lightness, blue and purple has the lowest lightness, and red and green are the intermediate lightness; the change of color brightness often affects the purity, for example, the brightness of red decreases after adding black, and the purity also decreases; if red and white are added, the lightness is improved, but the purity is reduced;

 

two : basic properties of common colors

(1) Red: red is a warm color, strong and extroverted, exciting and can leave a deep impression; red represents life, enthusiasm and vitality, giving people a vigorous and vigorous induction; in the traditional concept, red is often associated with auspiciousness, good luck and happiness; at the same time, red can make people feel fear, danger and agitation Only those occasions that need to have eye-catching signs will use pure red, and more often it is the harmonious color of red and other colors; for example, adding a small amount of blue in red will weaken its heat and tend to be elegant and gentle; adding a small amount of white in red will make it soft, and tend to be subtle, shy and delicate;

 

With pure red as the graphic color and the natural color of aluminum profiles as the background color, if properly matched, it can also give people a passionate but not too exciting visual effect; this practice must make the graphic lines and the natural color of aluminum profiles match well in space, two thousand and eight The figure on the torch of the 2008 Olympic Games is composed of red and aluminum, which gives people a warm, energetic but peaceful feeling;

 

(2) Yellow: yellow is indifferent, arrogant and sensitive. It is a kind of happy color with a little excitement. It is a very bright and delicate color. It has a strong sense of light and has a strong visual effect. It represents bright, brilliant, eye-catching and noble, which makes people feel happy. Pure yellow is rarely used for Aluminum profile Dyeing, but yellow as the basic color of gold is very common, in yellow to add other colors into the harmony color is also widely used, many colors are based on yellow to mix; for example, adding a small amount of blue in yellow, will make it into a fresh green, its arrogant character will disappear, tend to a peaceful, moist feeling If a small amount of red is added to yellow, it will have an obvious orange feeling, and its character will change from indifference and arrogance to a kind of warmth and warmth with a sense of propriety; when a small amount of black is added to yellow, the color sense and color property change greatly, which becomes a complex color impression with obvious olive green, and its color nature becomes mature and easy-going;

 

(3) Blue: Blue belongs to cold color, simple and introverted, is a kind of color that helps people to sober up; the simple and introverted character of blue often provides a far-reaching, broad and peaceful space for those colors with active personality and strong expansion tension, and becomes a friendly and modest friend to set off the lively colors; blue is still a kind of color that can still be strong after being diluted In color matching, blue can be used as the background color, while patterns and characters can be matched with other colors;

 

(4) Green: green is a cool color, which is between yellow and blue. It has the clarity of yellow and the quietness of blue. The softness of the two makes green in peace, tranquility and vitality. Green is the color of nature, which has the function of balancing human heart. At the same time, green is the landmark color of environmental protection. When there are more yellow elements in green, its character will change They tend to be lively, friendly and childish;

 

(5) Orange: orange is a mixed color of yellow and red, which is also a warm color. It is easy to be accepted by people. It represents warmth, liveliness and liveliness, giving people a sense of happiness. Some mature fruits and nutritious foods are mostly orange, so this color is suitable for occasions related to nutrition and sweetness. If there are more yellow components in orange, the color can be easily accepted, It tends to be beautiful and fragrant;

 

(6) Purple: purple represents mystery, nobility and majesty; it gives people a sense of elegance and grace; improving its brightness can produce charming and elegant effects; otherwise, it will lose its luster; but when the surface of aluminum profile needs to use purple, it should not make the purple too deep, but should make the purple lighter, which will show more charm, otherwise it will produce dull feeling;

 

(7) White: white gives the impression of peace and purity, which can show any charm. In anodizing of aluminum profiles, silver is a widely used treatment, but silver does not represent white Aluminum profile The first is to obtain the white effect through dyeing, and the second is to obtain the whitening effect in advance through pretreatment; the whitening is a very elegant color, which is also a common processing method for many advanced electronic product shells, and it can also give the metal a soft feeling, which is popular among women;

 

eight )Black: on the one hand, black symbolizes sadness, solemnity, death and despair; on the other hand, it gives people a deep, solemn and resolute feeling; in anodizing of aluminum profiles, black with strong metallic feeling and no reflection is a very high-grade color, which is also a common dyeing scheme for many high-end cases;
