The company's ultra-fine series of iron oxide pigment is to meet the needs of customers, the introduction of the index of henchmann coefficient, elaborate production of ultra-fine, easy to disperse new iron oxide pigments.
It not only has the superior performance of general iron oxide pigment, but also effectively prevents the aggregation tendency of pigment particles after being treated and ground by auxiliary agent, reduces the surface attraction between pigment particles in the application system, makes the pigment easy to disperse and greatly improves the storage stability.
When used, it only needs to disperse. The Hungerman coefficient of iron oxide red and iron oxide yellow is about 6.0, and the fineness is about 25 μ m; the Hungerman coefficient of iron oxide black is about 4.0, the fineness is about 50 μ m, and the coloring power is increased by 15% - 20%. Customers can shorten the grinding time, or cancel the grinding process, and appropriately reduce the use of pigments, whose main technical indicators have reached or exceeded the international requirements for ultra-fine products.
The company's latest ultra-fine series of iron oxide: ultra-fine iron oxide red 110m, 130m, 190m; ultra-fine iron oxide yellow 313M, 920m; ultra-fine iron oxide black 330m.
