Application of iron oxide pigment in cement building materials
Nowadays, there are a lot of colors on the surface of indoor
and outdoor buildings, which beautifies people's visual life. What
pigments are used in building materials and how to use them?
Because
of its beautiful and durable color, strong sunlight exposure and
climate change, alkali resistance and mortar resistance, the properties
of cement are not damaged. It has strong coloring power, the most suitable particle size and structure, and good dispersion. Therefore, it is applicable to the coloring of the following building
structures and cement products, various indoor and outdoor color
concrete surfaces and building surfaces, such as walls, floors, floor
tiles, roof tiles, panels, flumes, blocks, towers, color mortar, colored
surface tiles, ridge tiles. Terrazzo and mosaic tiles are used to decorate indoor and outdoor walls, ground floors, stairs, porches, passageways, etc. Artificial stone such as artificial marble, artificial tufa stone and so on. Asbestos cement is used to decorate wall panel, floor slab, roof tile, window sill and ladder.
Usage:
in concrete products, the amount of iron oxide pigment is limited to
1-10%. If the high limit is exceeded, the mechanical strength of the
products will decrease, generally 5-8%. At the same time, the iron oxide
pigment does not contain lead and zinc oxide,
