Physical properties: there are two kinds of iron oxide, natural and man-made. Natural is called Xihong. It is basically pure iron oxide and is a red powder. Due to different production methods and operating conditions, their crystal structure and physical properties are very different, and their color changes from orange light to blue light to purple light. Covering power and coloring power are great. Density 5-5.25. It has excellent light resistance, high temperature resistance, atmospheric influence resistance, dirty gas resistance and all alkalis resistance. Only when heated in concentrated acid will it gradually dissolve.
Main uses: in the building materials industry, iron oxide is mainly used for color cement, color cement floor tiles, color cement tiles, imitation glazed tiles, concrete floor tiles, color mortar, color asphalt, terrazzo, mosaic tiles, artificial marble and wall painting; Used for coloring and protecting various coatings, including water-based interior and exterior wall coatings, powder coatings, etc; It can also be applied to oily paints, including epoxy, alkyd, amino and other primers and topcoats; It can also be used for toy paint, decorative paint, furniture paint, electrophoretic paint and enamel paint. Iron red primer has anti rust function, which can replace high priced red lead paint and save non-ferrous metals.
