Do you know what aluminum pigments are? Speaking of aluminum pigments, many people think of pigments used in painting, in fact, aluminum pigments are not what we often say painting pigments, but an industrial raw material. However, with the development of plastics, coatings and other industries, many people have begun to understand aluminum silver paste and aluminum powder. Therefore, people have such an idea, aluminum silver paste, aluminum powder is not aluminum pigment?

Do you know what aluminum pigments are? According to Xiaobian understanding, aluminum pigments are mainly aluminum silver pulp, aluminum silver powder and spherical aluminum powder three categories, let Xu Yang Xiaobian to tell you about it.

1. Aluminum silver paste

Aluminum silver paste is also known as aluminum paste, silver paste, etc., the main components of the snow flake aluminum particles and petroleum solvents, generally showing a paste. The characteristics of distinguishing the high-quality aluminum silver paste are mainly manifested in: its aluminum sheet surface is smooth and flat, the particle size distribution is concentrated, the shape is regular, and has excellent light reflection ability and metal luster. In life to distinguish the excellent aluminum silver paste, can be identified by the aluminum silver paste "with the Angle of the color effect" principle, general aluminum silver paste and transparent color pigments mixed when used, will let the paint film reaction, through the display of decorative effect to distinguish. Generally gorgeous and beautiful, that is, better quality aluminum silver paste.

2, aluminum silver powder  

Aluminum silver powder is usually referred to as silver powder, in fact, it is flaky silver powder, so it is commonly known as aluminum silver powder or silver powder, and its chemical composition is mainly aluminum, non-silver. Powder coatings, inks, coatings and other special aluminum silver powder is composed of flat, bright, shear resistance, weather resistance, acid and alkali resistance good aluminum flake, because of its zero VOC emissions, in the furniture wood, cabinet supplies and other industries are widely used.

3, spherical aluminum powder

The spherical aluminum powder is named mainly because of its silver-white metallic luster, aluminum is a active metal, and a dense oxide film about 50 microns thick is immediately formed on the surface of aluminum in dry air, so that aluminum will not be further oxidized. Aluminum powder is an important and widely used industrial raw material in modern industry, and its application fields cover refractory materials, pigment coatings, ceramic alloys, chemical metallurgy, military industry and other industries. Raw aluminum powder according to the production process is different, the appearance of the electron microscope is mainly droplets and irregular two, aluminum purity is generally between 98-99.9%, the activity is generally between 96-99%, aluminum purity and active aluminum content are the two most important indicators to measure the quality of raw aluminum powder.
