Detailed introduction
Iron oxide brown is an inorganic pigment with excellent tinting strength and hiding power, which is widely used in many fields. The following is a detailed description of Iron oxide brown:
1. basic information
Chinese Name: Iron oxide Brown
English name:FE2O3 AS BROWN PIGMENT,Iron oxide,brown
Molecular formula: usually expressed as (Fe2O3 FeO)· nH2O, but the specific molecular formula may vary depending on the production process and product.
2. chemical properties
Appearance: Brown powder.
Solubility: insoluble in water, alcohol, ether, but soluble in hot acid.
Tinting power and hiding power: high, can give the material deep brown.
Light resistance, alkali resistance: good, able to maintain a stable color under a variety of environmental conditions.
Other characteristics: water permeability and oil permeability, color phase with different processes, there are yellow brown, red brown, black brown and other changes.
3. production methods
Ferrous sulfate oxidation method: Iron oxide brown is prepared by reacting ferrous sulfate with soda ash, washing, filtering, drying, crushing, mixing and other steps. The specific reaction equation is: FeSO4 Na2CO3[H2O]→(Fe2O3 FeO)· nH2O Na2SO4 CO2 ↑.
Mechanical mixing method: Iron oxide red, Iron oxide yellow, Iron oxide black and other pigments are mechanically mixed, and Iron oxide brown with different hues can be obtained by adjusting the proportion of different pigments.
4. use
Paint, ink: as a colorant, give paint, ink and other products rich brown.
Plastic, shoe powder: in plastic, shoe powder and other products play a coloring role, increase the beauty of the product.
Paint, building: used for paint and building materials coloring, such as interior and exterior wall paint, floor paint, ceramic tile, etc.
Rubber: As a colorant in rubber products, such as automobile tires, rubber tubes, etc.
5. Security and Storage
Safety: Iron oxide brown itself has low toxicity, but long-term inhalation of its dust may cause damage to the respiratory system, so you should pay attention to dust prevention measures when using it. The maximum allowable concentration of iron oxide aerosol (soot) is 5 mg/m ³.
Storage: should be stored in ventilated, dry warehouse, avoid high temperature and humid environment. At the same time, it should be stored in isolation with acid, alkali and other items to prevent chemical reactions. According to the correct storage conditions, the effective storage period of unpacked products can reach 3 years.
In summary, Iron oxide brown as an important inorganic pigment, has a wide range of applications in many fields. Its unique chemical properties and diverse production processes enable it to meet the needs of different fields and applications. During use and storage, attention should be paid to its safety and stability to ensure the quality and safety of the product.
