Introduction of Pigment Manufacturers

Huihong pigment is a colored fine particle powder material, generally insoluble in water, oil, solvent and resin and other media, can be dispersed in various media. It has hiding power, tinting power, and is relatively stable to light. It is often used to formulate coatings, inks, and color plastics and rubber, so it can also be called a colorant.

Pigments are different from dyes in that general dyes are soluble in water (the old distinction), while pigments are generally insoluble in water. Dyes are mainly used for dyeing textiles and other materials. However, this distinction is not very clear, because some dyes may also be insoluble in water, and pigments are also used for pigment printing and puree coloring of textiles. The chemical structure of pigments is similar to that of dyes, so it is usually regarded as a branch of dyes.

Pigment is a powdery substance used for coloring. It is insoluble in water, grease, resin, solvent and other media, but can be uniformly dispersed in these media and can color the media, and has excellent covering power. The basic requirements of pigments for art are that the finer the particles, the better, the brighter the color, the better, and the less discolored, the better (the stability is better). Watercolor paints are almost all transparent except for white. This can meet the needs of watercolor over-dyeing. Gouache paint was originally invented by adding white powder to watercolor paint to make the color opaque. Because watercolor paint is transparent, it is difficult to correct if you make a mistake. And gouache paint can be easily modified due to its opacity. Later, raw materials such as gum arabic were added to the gouache pigment to further improve its performance. Gum arabic gives gouache paint a glossy finish when it dries, but in special occasions that require flat application (such as renderings and coloring animations), the glue can form irregular spots on the surface of the paint, or cause the color to fade. Not uniform, so there are special degumming pigments.

Oil paints are paints diluted with oil. Chinese painting pigments are very rich, there are various types, from mineral powder to plant extraction to animal extraction, the types are complex. In theory, as long as there are three primary colors of red, yellow and blue, other colors can be adjusted, but the color purity is always not high enough, so modern art pigment manufacturers produce high-purity pigments for colors of various hues and lightness. Meet various needs. From the basic 12 colors of Z to the usual 24 colors or even 48 colors to more than 60 colors. Not including special metallic colors.

Pigments usually have the following properties: 1. Color. Color pigments are pigments that selectively absorb and scatter visible light energy, and can present yellow, red, blue, green and other colors under natural light conditions. 2. Tinting strength. The ability of a coloring pigment to absorb incident light. It can be expressed as a relative percentage of the tinting strength of a standard pigment sample. 3. Hiding power. The ability to cover the surface color of a substrate in a film-forming substance. It is usually expressed in grams of pigments contained in a paint covering an area of 1 square meter. 4. Light fastness. The ability of pigments to maintain their original color in the presence of light. Generally, the eight-level system is used, and the eight-level is the best. 5. Weather resistance. The ability of a pigment to maintain its original properties under natural or artificial climatic conditions. Generally, the five-level system is used, and the five-level system is the best. 6. Volatile matter. Mainly refers to moisture, generally not more than 1%. 7. Oil absorption. Refers to the number of grams of refined linseed oil required for 100 grams of pigment to form a uniform agglomerate. 8. Water-soluble matter. The water-soluble substances contained in the pigment are expressed as the mass percentage of the pigment. For paints used in paint, the water-soluble content is usually controlled below 1%.

Pigments can be divided into inorganic pigments and pigments from the chemical composition, and can be divided into natural pigments and synthetic pigments according to their sources. Natural pigments are derived from minerals, such as: cinnabar, laterite, realgar, malachite green and heavy calcium carbonate, wollastonite, barite powder, talc powder, mica powder, kaolin, etc. Biological sources, from animals: cochineal red, natural fish scale powder, etc.; from plants: garcinia cambogia, alizarin red, indigo, etc. Synthetic pigments are artificially synthesized, such as inorganic pigments such as titanium dioxide, zinc barium white, lead chrome yellow, iron blue, and pigments such as scarlet powder, even light yellow, phthalocyanine blue, and quinacridone. Classified by the function of pigments, such as anti-rust pigments, magnetic pigments, luminescent pigments, pearlescent pigments, conductive pigments, etc. Sorting by color is a convenient and easy to use method. Pigments can thus be classified as white, yellow, red, blue, green, brown, violet, black, regardless of their origin or chemical composition. Pigments can be classified according to the type of compound they contain: inorganic pigments can be subdivided into oxides, chromates, salts, silicates, borates, molybdates, phosphates, vanadates, ferricyanates, Hydroxides, sulfides, metals, etc.; pigments can be divided into azo pigments, phthalocyanine pigments, anthraquinone, indigo, quinacridone, dioxazine and other polycyclic pigments, arylmethane pigments according to the chemical structure of the compound Wait. From the perspective of production and manufacturing, it can be classified into titanium-based pigments, iron-based pigments, chromium-based pigments, lead-based pigments, zinc-based pigments, metal pigments, and synthetic pigments. This classification method has practical significance, and often a system can represent A pigment professional production industry. From the application point of view, it can be divided into paint pigments, ink pigments, plastic pigments, rubber pigments, ceramics and enamel pigments, pharmaceutical and cosmetic pigments, art pigments and so on. A variety of specialty pigments have some unique properties to meet the requirements of the application. Pigment manufacturers can also recommend a series of pigment products to professional users.
