They are used to obtain all kinds of paint and enamel coatings, as well as for the production of fire-resistant materials. today iron oxide pigments https://moskva.roshimprom.ru/products/pigments/ incredibly in demand in the industry
Production of iron oxide pigments
The production of iron oxide pigments is a whole technological process consisting of several stages. Iron oxide pigment is a powder made on the basis of iron oxide with impurities that improve its properties. According to their properties, iron oxide pigments are divided into coloring and auxiliary. Coloring pigments are used to produce paints, enamels, varnishes, fillers and primers. They contribute to obtaining a uniform color.
Depending on the purpose, three types of iron oxide pigments are distinguished:
- pigments for paints intended for painting metal;
- pigment for water-based paints;
- pigments in the form of powder, intended for use as an additive to clay, included in the composition of paints for wood.
The color of the iron oxide pigment depends on its composition and can be white, yellowish and red, as well as have other shades. Currently, black, red, and yellow iron oxides are used as iron oxide pigments. Due to low resistance to atmospheric effects, these pigments have not been widely distributed. But green iron oxides (sodium and potassium salts of ferrous potassium) and orange iron oxides (iron salts of sodium) are widely used in industry, as they retain their color for a long time.
What should be considered when choosing pigments
When mixed with organic solvents and water, iron oxide pigments form a suspension that is applied to the surface to obtain a paint coating. Depending on the composition, iron oxide can have different shades (from light red to dark brown). Iron oxide is an active dye and gives different colors as a result of chemical reactions. Depending on the type of oxides that make up the pigment, zinc, aluminum, magnesium, iron oxide and silica pigments are distinguished.
The use of pigments depends on the purposes for which they are used. For example, pigments for printing on paper are used as a binder when making printing forms.
