Introduction and main use of pigments
There are many kinds of pigments, which are tiny colored substances. They are a kind of pigment made of organic compounds. They are applied to the surface of the object to form a color layer, which can appear in certain colors. Generally divided into organic organic pigments and inorganic pigments, the difference between the two is that organic pigments have high tinting strength, and the particles are relatively easy to disperse and are not easy to precipitate. Generally used for coloring materials such as inks, coatings, plastic products, building materials, etc. . So where is the difference between pigments and dyes? Many people can't say it. The following is a professional introduction of chrome yellow Pengcheng Chemical Co., Ltd. to introduce you in detail.
Pigment is an indispensable raw material in the paint manufacturing process. It can make the coating have a certain hiding power, increase the color and protection, and make up for the defects of the paint. Not only that, but also in the coating, it can enhance it. The strength of the coating itself, by preventing the penetration of ultraviolet light, also promotes the anti-aging effect of the coating. A variety of different pigments have a variety of different uses.
In the coatings industry, coloring pigments enhance the durability, weather resistance, abrasion resistance and other properties of the film in addition to the color and hiding properties required for the film.
The anti-rust pigment mainly prevents the metal from rusting. In the atmosphere, especially in a humid environment or other corrosive gas, the steel is easily rusted and corroded, and in severe cases, the structure may be damaged or even not used. In order to prevent metal rust, there are many methods, such as pond porcelain, electroplating, etc., in which the use of paint is a relatively simple and common method. Commonly used pigments with good rust resistance are: red dan, iron red, zinc yellow, barium metaborate, silver calcium yellow and so on.
The above is the introduction and main use of pigments. It is also possible to select pigments of different nature according to different objects of use. In fact, pigments are used in many industries, such as some plastics industry, printing industry, paper industry, synthetic fiber industry, etc. It can be seen that the use of chrome yellow pigments is still relatively extensive.
