Iron Oxide Black Pigment For Construction Materials
Property:
As a common pigment, iron oxide black is a small black granular solid. Iron oxide black is widely used, widely used in coatings, construction and marble, ground ceramics, paint, ink, rubber, plastics and other fields In industrial coloring, the product has good physical and chemical properties, strong coloring power, high hiding power, and good light and weather resistance. It is very suitable for outdoor equipment coloring and can ensure long-term bright color. It is easy to be oxidized when exposed to high temperature, and it will not cause any environmental pollution during use, and iron oxide black can be perfectly mixed with most solvents and media, which is convenient to use.
Iron oxide black has excellent physical and chemical properties. Strong hiding power, high tinting power, soft color, stable performance, and non-toxic. It is a green and environmentally friendly pigment; alkali resistant, stable to weak and dilute acids, excellent light resistance and heat resistance, soluble in water , Has excellent anti-rust and anti-ultraviolet effects. Mainly used in colored cement parts, plastics, rubber, ceramics, paint, building materials, etc.
The full name of iron black is iron oxide black, which is a black inorganic pigment with ferroferric oxide as the main component, and its chemical formula is Fe3O4 or Fe2O3·FeO. The appearance is black powder, the refractive index is 2.42, the particles are cubic, the coloring power and hiding power are high, ACID, alkali, light and easy to disperse, heat-resistant to 100 ℃, burned at 200 ~ 300 ℃ to form γ-trioxide Second iron, high temperature oxidation to red α-iron trioxide. Iron oxide black can be prepared with ferrous solution, alkali and oxygen (ferrous oxidation method), or ferrous sulfate can be made from iron filings and sulfuric acid, and then made into ferrous hydroxide with caustic soda at a certain temperature and pH It is formed by adduct with ferric oxide, and can also be prepared by aniline method. It is mainly used for the coloring of paints, inks, and building materials, and can also be used in the electronics and telecommunications industries.
