Alkali Resistance and Color Permanence of Green Iron Oxide Pigment in Cementitious Systems
Chemical Synergy and pH Stability
In high-pH environments, such as fresh concrete or cementitious mortars where the pH can reach 12–13, many organic pigments undergo chemical degradation, leading to rapid fading. Green iron oxide pigment is a high-performance composite material engineered by precisely blending inorganic iron oxide yellow (alpha-FeOOH) with stable organic pigments like phthalocyanine blue. Deqing Demi Pigment Technology Co., Ltd. utilizes a specialized manufacturing process that ensures the inorganic component acts as a protective carrier. This structure is inherently resistant to alkaline attack, preventing the saponification or hydrolysis that typically destroys lesser pigments. By maintaining structural integrity within the cement matrix, our green oxide ensures that architectural finishes retain their vibrant hue for decades without chalking or shifting.
Technical Advantages for Architectural Finishes
- Alkali Inertness: The composite pigments from Deqing Demi Pigment Technology Co., Ltd. are chemically inert to calcium hydroxide, the primary byproduct of cement hydration, ensuring no chemical reaction occurs that would alter the pigment's color.
- UV and Weather Resistance: Beyond alkali resistance, our green iron oxide pigment provides exceptional lightfastness. This is critical for exterior architectural finishes that face simultaneous exposure to high-alkalinity substrates and intense solar radiation.
- Uniform Dispersion: Our micronized series allows the pigment particles to integrate evenly within the cement paste, reducing the risk of localized color clusters or "floating," which can lead to uneven fading patterns.
Technical Parameter Comparison: Standard vs. Composite Green Oxide
| Technical Property | Organic Green Dye/Pigment | Composite Green Iron Oxide (Demei) |
| Alkali Resistance (1-5 Scale) | 1 - 2 (Poor) | 4 - 5 (Excellent) |
| pH Stability Range | Narrow (Acidic to Neutral) | Broad (3 - 13) |
| Lightfastness (1-8 Scale) | 4 - 5 | 7 - 8 |
| Fe2O3 Component (%) | 0% | 85% - 90% (Inorganic base) |
| Heat Stability | Low (<150°C) | Moderate to High (Up to 200°C) |

Q3: What are the application benefits of using micronized green iron oxide from Demei?
The micronized series from Deqing Demi Pigment Technology Co., Ltd. features superior fineness and reduced oil absorption. For the user, this translates to faster dispersion in water-based architectural coatings and more efficient color development in dry-mix mortars. This high-stability series helps reduce overall pigment consumption while caring for the health of employees by minimizing dust during the mixing process.
Technical Factors Influencing Dispersion Speed of Green Iron Oxide Powder in Water-Based Primers
Particle Engineering and Surface Energy
In water-based industrial primers, the dispersion speed of green iron oxide powder is primarily dictated by the interaction between the pigment surface and the aqueous medium. Since green iron oxide is a composite pigment, achieving a rapid and stable "wet-out" is critical. Deqing Demi Pigment Technology Co., Ltd. focuses on controlling the surface tension of our pigments through advanced R&D. Key technical factors include the hydrophilicity of the pigment surface and the presence of any residual salts from the manufacturing process. High-purity pigments with controlled surface energy reduce the induction period during mixing, allowing the particles to transition from dry powder to a fully stabilized suspension more quickly.
Micronization and Aggregate Strength
- Particle Size Distribution: The presence of large aggregates significantly slows down dispersion. Deqing Demi Pigment Technology Co., Ltd. utilizes specialized milling technology for our green iron oxide powder to break down these aggregates into primary particles, ensuring a narrower size distribution.
- Mechanical Sheer Requirements: Micronized series pigments require lower shear force to reach a target Hegman fineness. This not only increases production speed but also protects the integrity of sensitive water-based resins.
- Wetting Agent Compatibility: The chemical treatments applied to our high-performance composite pigments are designed to be compatible with modern non-ionic and anionic dispersants commonly used in industrial primers.
Technical Parameter Comparison: Standard vs. Micronized Green Powder
| Technical Parameter | Standard Green Iron Oxide | Micronized Green Iron Oxide (Demei) |
| Average Particle Size (μm) | 0.4 - 0.9 | 0.1 - 0.3 |
| Hegman Fineness (Grind) | 40μm - 55μm | 10μm - 20μm |
| Oil Absorption (g/100g) | 28 - 35 | 20 - 26 |
| Sieve Residue (45μm) | ≤ 0.5% | ≤ 0.1% |
| Dispersion Speed Score | Standard | Excellent (30% Faster) |
