Iron Oxide With Excellent Anti-rust Anti-infrared And So On
Iron oxide has excellent physical and chemical properties. Strong hiding power, high color strength, soft color, stable performance, alkali, weak acid and dilute acid has a certain stability, with excellent light resistance, weather resistance, insoluble in water and organic solvents, with excellent rust Anti-infrared and so on.
Iron oxide functional use
Heat-resistant grade iron oxide series is through the dispersant, powder pigments and other chemical synthesis through the interface, compared with ordinary iron oxide pigments in the application process has several advantages:
First, excellent anti-flocculation performance, easy to disperse, so that the stability of the dispersion increased;
Second, good weather fastness, used in coatings, can improve the coating luster, and with the temperature change color is more stable;
Third, the ultra-strong chemical resistance, product acid and alkali performance improved;
Fourth, the superior heat resistance, making the powder particles at a high temperature in a relatively stable state, making the product has a wider range of applications. Ferric oxide is the main component of rust. The main cause of rust is iron metal in the presence of impurity carbon, and the environment of water and oxygen reaction, iron metal will rust. Used in paint, ink, rubber and other industries, can do catalyst, glass, precious stones, metal polishing agent, can be used as iron ore raw materials. The largest application of iron oxide is used as a pigment. Iron oxide is composed of iron oxide red, iron oxide black (and iron oxide yellow) mixed; Iron oxide is composed of blue phthalocyanine blue and iron oxide yellow.
Stability: stable, soluble in hydrochloric acid, dilute sulfuric acid to produce +3 valent iron salts. The iron element forms ferrous ions in the displacement reaction.
Storage conditions: stored in a dry place, do not make moisture, to avoid high temperature, and acid and alkali isolation. According to the above conditions, the unpackaged product has an effective storage period of three years.
Solubility: insoluble in water, not with water. Dissolved in acid, and acid reaction. Not with NaOH.
Oxidation: high temperature by CO, H₂, Al, C, Si and other reduction.
