Iron oxide red has stable sunlight, particles, and a stable structure in the atmosphere. It can react with many chemicals, such as iron oxide red and stearic acid.
Iron oxide red reacts with stearic acid in animals and plants to produce sodium stearate. When its concentration is low, it will be defatted; If its concentration is too high, the solubility of sodium stearate and surfactants will deteriorate washability, and it will also be difficult to wash after degreasing.
1. Alkali resistance: Stable to soda ash and other types of alkaline substances, especially steel and lime sand slurry used in construction. In addition, it will not act as building powder on steel structures, nor will it affect their strength.
2. Acid resistant: Has a certain tolerance to common weak and dilute acids, but can gradually dissolve in strong acids, especially under heating and concentration conditions.
3. Light resistance: The color of iron oxide red will not change under strong sunlight.
4. Heat resistance: Iron oxide red is stable within a certain temperature range, and its color will change beyond this temperature range. As the temperature increases, the degree of change becomes increasingly prominent.
5. Weathering: not affected by adverse weather conditions such as cold, heat, and humidity.
6. Anti turbidity oxygen: Stable in turbid gases such as hydrogen sulfide, carbon oxides, sulfur oxides, and nitrogen oxides.
7. Penetration: Iron oxide red is insoluble in water, white oil, vegetable oil and other fluxes, and there is no penetration phenomenon.
Through these descriptions, I believe everyone's understanding of iron oxide red is becoming deeper and deeper. Pay attention to its wet process products, which have fine crystals, soft particles, are easy to grind, and are suitable for use as pigments. Dry crystals are large and hard particles, suitable for magnetic materials and polishing and grinding materials.
