1 What is pickling Iron Oxide Red
Pickling Ferric Oxide red takes a large number of steel plate pickling waste liquid discharged by iron and steel enterprises as raw materials, and recycles valuable metals in the pickling waste liquid. The ferric oxide (Fe2O3) obtained from the wet treatment of pickling waste liquid with ferric oxide red is called pickling ferric oxide red.
The spray roasting method can also be used to treat pickling waste liquid pretreatment, impurity removal, synthesis, water washing, drying, calcination and other processes to prepare Iron Oxide red (a-Fe2O) without silicon, aluminum and other impurities, which has uniform particle size and consistent crystal form, namely high-purity iron oxide red. This iron oxide red is the main raw material of soft magnetic ferrite materials, accounting for about 70% of the total amount of raw materials. According to statistics, the production of soft ferrite in China will reach 400 kf4 by 2020.
2. What are the characteristics of acid washed iron oxide red?
Compared with iron oxide red prepared by other methods, acid washed iron oxide red contains more ferric oxide, has strong covering ability, high coloring rate, soft color and stable performance. Acid washed iron oxide red will not dissolve with water when it is immersed in water, so that iron oxide red will dissolve. Pickled iron oxide red has the characteristics and functions of maintaining its original performance in any climate, so it has the advantages of being more resistant to corrosion, ultraviolet radiation, etc.
As the raw material of acid pickling ferric oxide red comes from industrial waste liquid, it plays a positive role in waste reuse, environmental protection and national carbon neutralization.
3. Use of Pickled Iron Oxide Red
Pickled iron oxide red is mainly used in industrial production:
Pickled iron oxide red can be used as pigment or colorant in various kinds of cement and concrete. It is simple to use and can be directly mixed in cement;
Pickled iron oxide red can be used in walls, floors, ceilings, stations and other fields;
Pickled iron oxide red, especially the iron oxide red primer with antirust function, can replace some expensive paint tools, saving costs and metal minerals
The high-purity acid washed ferric oxide red with a purity of 99.3% can also be used to produce high-grade soft ferrite material 501.

Although the raw materials for the preparation of acid pickling ferric oxide red mainly come from the acid pickling waste liquid of the steel plant, with low raw material cost and relatively high cost performance, the market price is relatively higher than that of iron oxide red produced by other methods due to the complex production process and better quality of the finished product of iron oxide red.
