2019-11-06 14:50:01
Iron oxide pigment is a kind of inorganic color material with a large quantity and a wide range. It is widely used in building materials, coatings, inks, rubber, plastics, ceramics, glass products, hardware, glass polishing, drama oil paint, painting, Cosmetics, drug coloring, photocopying materials, catalysts, electronics industry, and magnetic memory materials for audio and video recording.
1. High degree of chemical stability and physical fastness:
(1) Alkali resistance: For any concentration of alkalis and other types of alkaline substances, especially for construction. Commonly used cement, lime mortar, etc., are very stable, and do not pulverize cement building components, nor affect their strength.
(2) Acid resistance: It has certain resistance to general weak acids and dilute acids, but it can also gradually dissolve in strong acids, especially under warm and thick conditions.
(3) Light fastness: The color will not change under strong sunlight.
(4) Heat resistance: It is stable within a certain temperature limit, and the color starts to change when it exceeds its temperature limit. As the temperature increases, the degree of change becomes more significant. The temperature limits of each variety are as follows: Iron yellow over 130℃ gradually changes color to red phase; Iron oxide red over 300℃ gradually changes color to deep red; Iron oxide violet over 400℃ gradually changes color to deep red; Iron oxide black over 100℃ gradually changes color to dark red; Iron oxide brown over 130℃ gradually changes color to red phase; Iron oxide green over 200℃ and gradually changes color to dark red.
(5) Weather resistance: Not affected by atmospheric cold, heat, dry, or wet weather conditions.
(6) Resistant to dirty air: It is very stable in any dirty gas, such as hydrogen sulfide, carbon oxide, sulfur oxide, hydrogen chloride, nitrogen oxide, and other gases.
(7) Water, oil, and solvent resistance: Insoluble in water, various mineral oils, vegetable oils, ethers, esters, ketones, etc., and other organic solvents, and there is no penetration.
2. Clear color and a unique hue.
The color of the iron oxide pigment is very clear and pure, and it does not use other organic or inorganic pigments to add color. Although it is not as bright and eye-catching as some organic pigments or other pigments, the tones of iron oxide pigments have a unique style, and their soft and harmonious tones are pleasing to the eye, suitable for residential, public places, indoor, and outdoor coatings. Its solemn tone is especially suitable for luxurious buildings and grand and dignified construction projects.
3. Excellent economic effects.
Iron oxide pigments have high tinting strength, fine and uniform particle size, which guarantees their use value, plus a lower price, guaranteeing the user's economic effect.
