BR602 / BR604 titanium chrome yellow (PigmentBrown24)

Yellow pigment composed of titanium, chromium and antimony, with high tinting strength, hue from red phase to green phase, excellent chemical resistance, outdoor weatherability, thermal stability, light fastness and impermeability , No migration, and high solar reflectance for use in RPVC, polyolefins, engineered resins, high temperature coatings and industrial coil coatings, as well as blends with high performance organic pigments.

structure

Titanium yellow is a high-temperature inorganic pigments, often xTiO2-yCr2O3 or (NiO) -zSb205 to indicate its chemical composition.

Titanium yellow crystal structure and rutile TiO2 the same.

Compared with the traditional inorganic pigments, rutile titanium pigment has a series of advantages in the chemical structure, the rutile titanium pigment is a solid solution, that is, a variety of metal oxides evenly distributed in the new chemical complex lattice As if in solution, but in a solid state.

Titanium yellow pigments are highly inert chemical compounds and are non-toxic pigments. They are completely suitable for safety systems requiring no poison to human body, such as children's plastic toys and coatings, food packaging materials, medical supplies, cosmetics and sanitary appliances.

Due to the high temperature calcination reaction, the titanium yellow pigment has a stable crystal form and lattice structure. Its properties of light resistance, heat resistance, weather resistance and resistance to various chemical medias are very good, and its anti-chalking properties surpass that of rutile titanium dioxide.

Determination of titanium chromium yellow powder by X-ray powder diffraction, the product of a high degree of crystallization. The presence of impurity peaks containing chromium and an antimony-containing phase is substantially absent in the spectrum because chromium and antimony are uniformly and stably dispersed in the lattice of titanium dioxide rather than independently.

Manufacturing process

By metal oxides or metal salts such as: titanium white, antimony white powder, chromium oxide, nickel carbonate and a small amount of additives, mixed, high temperature calcination crystal, and then ultrafine grinding, fight and prepared.

The calcination process is carried out continuously in a kiln or tunnel kiln, or in a batch furnace. Add mineralizer can reduce the reaction temperature of the pigment, and other additives used in the formula on the color brightness has a greater impact. After calcination, the final product must be micronized to a particle size of about 1 micron.

Before the packaging must be spelled to ensure that the total color difference between each batch of products? E ≤ 0.5.
