Now iron oxide red has been widely used in various industries
Iron oxide (ferric oxide), chemical formula Fe2O3, also known as burning limonite, burning ocher soil, iron Dan, iron red, red powder, etc. It looks like red powder. Iron oxide soluble in strong acid, strong acid, its red brown powder for a low pigment, industrial called iron oxide red, used in paint, ink, rubber and other industries, can be used as a catalyst, glass, gems, metal polishing agent, can be used as raw materials for ironmaking.

Why iron oxide red is widely used in coatings
When the particle size of iron oxide red is 0.2μm, the particle size is yellow, and the specific surface area and oil absorption are also large. When the particle size increases, the hue moves from red to purple. The specific surface area and oil absorption also become smaller. Iron oxide red is widely used in antirust coatings with physical antirust function. Water in the atmosphere cannot penetrate into the metal layer and can increase the compactness and mechanical strength of the coating.

Iron oxide red color test techniques and detailed test methods
At present, iron oxide red is mainly divided into two categories, one is the color comparison method, that is, with the reference sample visual or instrument test to give the results; the other is the direct color measurement method, that is, the use of instruments or visual directly give the color of the value or sample number. According to these test methods, we can know whether the color value of iron oxide red is in line with the national standard culture for production, which provides an important reference basis for purchasing iron oxide red or judging the quality of iron oxide red.
