Color of metal powder

Color of metal powder
Metal is defined as: a material that has a characteristic luster and is opaque, malleable, ductile, thermally conductive, and electrically conductive.
Commonly used metal powders are aluminum powder, zinc powder, lead powder, metal powder in the form of alloys are copper zinc powder, zinc aluminum powder, stainless steel powder and so on.
Compared with other pigments, metallic pigments have their particularity. Because powdered metallic pigments are composed of metals or alloys, they have bright metallic luster and color. Many metal pigments are used as decorative pigments, such as copper and zinc. Powder, its hue from pale gold to red gold, makes the painted items colorful; aluminum pink phase silver, also used for decoration. In recent years, a new variety of aluminum powder flash aluminum powder and transparent pigments, the coating surface not only There are metal highlights, and colorful, the decorative effect is very good; the scaly zinc powder is slightly light metallic light, which can make the painting mixed with the surrounding scenery, with camouflage effect.
Most of the metallic pigments are scaly powders, which are transferred into the film-forming material and coated into a film, which is parallel to the object to be coated like a deciduous floor, which is connected to each other, covered with each other, arranged in multiple layers to form a barrier, and metal scales are blocked. The micropores of the film-forming material are broken, and the penetration of harmful gases or liquids in the coating film is prevented, and the coating film and the article to be coated are protected, which is the anti-corrosion ability of the physical shielding, and the zinc powder has the shielding ability. And cathodic protection, a large amount of zinc powder is connected to each other as a conductive layer in the coating film. When the coating encounters electrochemical corrosion, since zinc has a negative electrode potential difference than iron, it is first corroded, thereby protecting the steel. Substrate. Stainless steel powder has good chemical stability and can prevent chemical corrosion.
The light-colored, high-gloss metal powder also has the ability to keep warm. This type of metal powder absorbs almost no light and reflects visible light and ultraviolet light. It is also suitable for heat radiation. Therefore, it can be used on articles that require heat preservation and light and heat radiation. For example, in the storage of oil, gas tanks and towers, the metal powder can reflect more than 60% of the ultraviolet rays in sunlight, so it can prevent the coating film from aging due to ultraviolet light irradiation, which is beneficial to prolong the life of the coating film.
Metallic pigments are extremely fine powders, and are mostly scaly, but also spherical, teardrop-shaped, and dendritic, all related to their manufacturing methods. Metal powders must be surface treated to have pigment characteristics such as dispersibility and hiding power. Different surface treatments can make the metal lipophilic or hydrophilic to suit different coating requirements.
