Walking around the walls of the school sports grounds, the airport runways and the tourist palaces, we see all kinds of reds, including iron oxide red, the crystallization of iron oxide red used in the concrete field. So, in the concrete field, how to use iron oxide red?
Iron oxide red in fabrication and construction products in all kinds of concrete material as a paint or stain, can be directly transferred to use, such as a variety of indoor and outdoor color concrete surface, such as metope, floor, ceiling, pillar, porch, roads, parking lots, ladder, station, etc., all kinds of building ceramics and glass ceramics, such as brick, floor tile, roof tile, panels, terrazzo, Mosaic tiles, artificial marble, etc. The specific application methods are as follows:
In concrete products, the amount of iron oxide red is limited to 1 ~ 10%, too high limit will reduce the mechanical strength of products, usually 5-8% is appropriate, iron oxide red contains lead, zinc oxide these two compounds will affect the setting time and setting strength.
Concrete products sometimes have cured at above 200 ℃ hot pressing, so about 180 ℃ can be converted into iron oxide red of black and brown iron oxide must first through thermal stability. If applied to terrazzo, the bottom layer is 2 ~ 3 cm thick, the surface layer is 15 cm thick.
Iron oxide red is used in the concrete field, is the use of iron oxide red excellent weather resistance, alkali resistance, light resistance, these functions are not other inorganic pigments or organic pigments can have.
It is understood that in order to protect land resources, our country to ban the use of clay brick and tile, these promote the development of the iron oxide red is used for concrete field, more and more get the welcome of vendor quality oxide red, iron oxide red manufacturers the bright paint manufacturing co., LTD., hebei province in the concrete application areas has nearly 10 years of accumulation of precipitation, in terms of "how to use iron oxide red is experienced.
