The main component of iron oxide blue pigment is magnetite, and the crystal belongs to the oxide mineral of the equiaxed crystal system. Because of its magnetism, it was also called Cishi, Magnet, and Xuanshi in ancient China. It has strong magnetism, which is the strongest among minerals and can be attracted by permanent magnets. Iron oxide blue is a dark blue and light blue powder, bright color, strong tinting power, and slightly poor hiding power. The powder is harder. Quality standard: coloring power 95-105%, oil absorption 15-30%, moisture 1.0%, sieve residue (200 mesh sieve) ≤ 1.0%, water-soluble matter 1.0%.

Feature of Iron Oxide Blue Pigment:

Dark blue or light blue powder, bright color, strong coloring power, slightly poor hiding power. The powder is harder. Quality standard: coloring power 95-105%, oil absorption 15-30%, moisture 1.0%, sieve residue (200 mesh sieve) ≤ 1.0%, water-soluble matter 1.0%.

Iron oxide blue has high tinting strength, good light resistance, poor alkali resistance, and high heat resistance. The temperature exceeds 150 degrees and loses crystal water and begins to decompose. Uses: paint, ink, painting, paint and crayons, paint varnished cloth, lacquer paper, plastic products coloring, building floors, floor tiles, etc.

Application

1. Iron oxide blue pigment is suitable for the coloring of plastic products, such as thermosetting plastics and thermoplastics, and the coloring of rubber products, such as automobile inner tubes, airplane inner tubes, bicycle inner tubes, etc.

2. In other industries, such as ceramics, enamel, rubber, plastics, leather polishing paste, etc., iron oxide blue is used as a colorant and filler.
