Iron oxide red has strong covering and coloring power, is stable in the atmosphere and sunlight, and is resistant to dirt, high temperature, and alkali. How to clean the residue left after the preparation of this substance?
1. After dilution and stirring, the sludge from iron oxide red is pumped by a mud pump to a plate and frame filter. The filtrate enters the sedimentation tank, and the filter cake is kept under pressure for about 40 minutes before being washed with water. The washing solution enters a small water storage tank. After being dried with compressed air for about 20 minutes, the filter cake is guided by a guide plate to a belt conveyor and then manually transported to the slag yard.
The dilute waste acid in the mud storage tank is used to adjust the sludge concentration, and the water is used to clean the mud storage tank. Heat resistant iron oxide pigments are particularly suitable for automotive coatings, automotive repair coatings, coil coatings, industrial coatings, various colorants, high gloss white coatings, and ceramic blanks.
2. The excellent heat resistance keeps the iron oxide red powder particles in a relatively stable state at high temperatures, which makes the product have a wider range of applications.
3. Good weather resistance. When applied to iron oxide red coating, it can improve the glossiness of the coating and make the color more stable with temperature changes.
