Iron Oxide Red With Light-resistant High Temperature Performance
Red iron oxide, also known as red rust, is a red iron oxide powder, with light resistance, high temperature performance. Its appearance is orange to purple ternary crystal powder, there are two natural and synthetic.
Appearance: orange red to purple tripartite crystal powder. There are two kinds of natural and synthetic. Naturally known as red west, the relative density of 55.25. Fineness 0.4 ~ 20um. Melting point 1565 (decomposition). Release oxygen when burned, hydrogen and carbon dioxide can be reduced to iron. Do not dissolve in water, soluble in hydrochloric acid, sulfuric acid, slightly soluble in nitric acid and ferment. With excellent light resistance, high temperature, acid, alkali, rust-proof. Dispersion is good, strong coloring and hiding power, no oil permeability and water permeability. Non-toxic. Air maximum allowable concentration of 5mg / m3.
The main purpose
1, Mainly used in building materials industry for color cement, colored cement floor tile, colored cement tile, imitation glazed tile, concrete floor tile, color mortar, colored asphalt, terrazzo, mosaic tile, artificial marble and wall painting;
2, for a variety of paint coloring and protection of materials, including water-based interior and exterior coatings, powder coatings, etc .; also apply to the oil paint, including epoxy, alkyd, amino and other primers and topcoats; , Decorative paint, furniture paint, electrophoretic paint and enamel. Iron-red primer with anti-rust function, can replace the expensive red lead paint, save non-ferrous metals.
3, for the coloring of plastic products, such as thermosetting plastics and thermoplastics, and rubber coloring, such as automobile inner tubes, aircraft inner tubes, bicycle tubes and so on.
4, for advanced refining materials, used in precision metal instruments, optical glass polishing. High purity powder metallurgy is the main base for the smelting of various magnetic alloys and other high alloy steel. Ferrous sulfate or iron oxide yellow or iron mixed by calcination at high temperature, or directly from the liquid medium.
