Red iron oxide in the development and application of coatings

Our iron oxide red, the economic environment, the raw material used as a pigment, a perfect fit. Next, we take a look to understand that the development of environmentally friendly and red iron oxide in the coating application bar.
Development and red iron oxide in the  plastic additive coating in the application:
In the oxygen steel converter process, high temperature steam iron in an oxygen rich conditions, the oxidation condensation aerosols or cohesion quickly oxidized to fine spherical oxide particles (spherical surface with minimal free energy), the time to conversion of α-Fe2O3'll be blown or pulled out of the high temperature zone, the gas phase of Fe3O4 and FeO forms preserved to show its ferromagnetic properties. This process is similar to the formation of the production process of synthetic iron oxide red ferric hydroxide gel is dehydrated crystalline α-Fe2O3, and thereby gives the pigment properties.
BOF dust and sludge produced in the polyethylene oxide  process of red iron oxide, is essentially a process of removing impurities to the thick, which is due to formation of dust and mud determined complex environment, the environment in the oxygen steel converter, there must be refractory debris, alkaline flux of dust and splashing droplets of molten steel into the inside of the flue dust mixed with mud and become part of it. Subtle temperature materials often also a steam iron core cohesion, while molten droplets larger than 20 microns can not fully oxidized and become black particles must be removed. Therefore, the processing of dust and mud out of coarse screening, mainly to remove refractory, metallurgical flux debris and small steel particles, hydraulic classification is not fully oxidized primarily to remove  tin stabilizer particles or low iron oxides.
BOF dust and sludge production of iron oxide red paint with good performance, small size, easy to disperse, with a stable nature, several Baidu can withstand high temperatures, especially with excellent anti-settling properties, mainly from two aspects: One converter iron red with good magnetic properties, the magnetic domain of the magnetic proximity unit will be arranged in a certain orientation of the magnetic force of the magnetic gel, excluding the caking tendency of sink to the bottom; the other hand, the pigment fine particle size, large specific surface area, surface free energy large, fully wetted by the resin wrapped, suspension excellent, not easy to sink to the bottom, thereby enhancing the stability of the paint.
