Ferrous sulfate oxidation method. Sulfuric acid reacts with iron filings to produce ferrous sulfate. Sodium hydroxide is added and air is introduced to oxidize to prepare crystal nuclei. Then, ferrous sulfate and iron filings are added to the crystal nucleus suspension, heated and blown into air to oxidize. Press filtering, rinsing, drying, and crushing to obtain iron oxide yellow.

Product description

Ferrous sulfate oxidation method. Sulfuric acid reacts with iron filings to produce ferrous sulfate. Sodium hydroxide is added and air is introduced to oxidize to prepare crystal nuclei. Then, ferrous sulfate and iron filings are added to the crystal nucleus suspension, heated and blown into air to oxidize. Press filtering, rinsing, drying, and crushing to obtain iron oxide yellow. It is a kind of iron oxide hydrate, and its shade ranges from lemon yellow to orange yellow. Alkali-resistant, acid-resistant, and high-temperature resistant, it will be dehydrated into iron oxide red when heated over 150°C. Light resistance, weather resistance and foul gas resistance are strong, and the tinting strength is almost equal to that of lead yellow. Iron oxide yellow pigment is suitable for the coloring of plastic products, such as thermosetting plastics and thermoplastics, and the coloring of rubber products, such as automobile inner tubes, airplane inner tubes, bicycle inner tubes, etc.
