How are organic pigments classified? Pigments made from colored organic compounds are called organic pigments. A class of pigments made of organic compounds that have color and a range of other pigment characteristics. The characteristics of the pigment include light resistance, water resistance, acid resistance, alkali resistance, organic solvent resistance, heat resistance, crystal stability, dispersion and hiding power. The difference between organic pigment and dye is that it has no affinity with the colored object, and only the organic pigment is attached to the surface of the object by adhesive or film-forming material, or mixed inside the object, so that the object is colored. The intermediates, production equipment and synthesis process required for its production are similar to the production of dyes, so organic pigments are often organized in the dye industry. Compared with general inorganic pigments, organic pigments usually have higher tinting strength, particles are easy to grind and disperse, not easy to precipitate, and the color is bright, but the light resistance, heat resistance and weather resistance are poor. Organic pigments are widely used in ink, paint, rubber products, plastic products, stationery and building materials and other materials coloring. According to the structure classification: (1) azo pigments account for 59% (2) phthalocyanine pigments account for 24% (3) triarylmethane pigments account for 8% (4) special pigments account for 6% (5) polycyclic pigments account for 3% organic pigments with bright colors and strong coloring power; The density is small and non-toxic, but the light resistance, heat resistance, solvent resistance and migration resistance of some varieties are often inferior to inorganic pigments. The variety of colors is endless and colorful, but there is a certain internal relationship between the various colors. Each color can be determined by three parameters, namely hue, lightness and saturation. Tone is the color of the characteristics of the difference between each other, determined by the color spectrum of the light source and the surface of the object emitted by the wavelength of the human eye to produce the feeling, can distinguish red, yellow, green, blue, purple and other characteristics. Brightness, also known as brightness, is the characteristic value that indicates the change of brightness and darkness on the surface of an object. By comparing the brightness of various colors, the color has the distinction of brightness and darkness.

Selection and function of high temperature resistant pigments

Pigments not only play the role of coloring in high temperature pigments, but also play a reinforcing role in the base material. Common pigments are mostly inorganic compounds, such as titanium dioxide, carbon black, iron oxide red, chrome green, ultramarine, chrome yellow, etc. Organic pigments toluidine red, phthalocyanine blue and phthalocyanine green are also very stable pigments. Carbon black is the most commonly used pigment in high temperature resistant paint. It has reinforcing effect on most rubber base materials and can greatly improve the physical and mechanical properties of the base materials without any compounding agent. This shows that the base materials and carbon black are only a physical process of lubrication, dispersion and wrapping, and there are chemical bonds in combination, thus increasing the strength of the base materials. Silicates such as high temperature pigment clay, talcum powder and diatomite can be used as fillers for high temperature resistant protective coatings. Fillers can improve the process performance of the base material, improve the heat resistance, wear resistance and chemical resistance of the coating. At the same time, the filler is cheap, which can reduce the cost of the coating, and can improve the tensile strength and physical and mechanical properties of the coating. high temperature pigment

Art paint "money" scene trend, clay figurine tribe take you "wall" to take the lead!

The eagle galloping on the prairie has not sounded for three years. Once it suddenly realizes, it is a blockbuster, and there are also three years of not flying. right time, right place, with right people., it will soar into the sky, which is amazing! Many people firmly believe that they are also heroic eagle, but suffer from the lack of a good platform to let them do their best. They lament that they have the age of childhood envy, but they have not become the envy of childhood. Today, there is no need to be sad. The little editor takes your "wall" to take the lead and find the dawn of life! From "0" to "1" in the 21st century-where does our business begin? Some people used to ask why the United States is a developed country, while China is now very prosperous, and why
