Industrial Applications of Pigment Geen 7
| Industry | Application | Process |
|---|---|---|
| Paints & Coatings | Used as a green pigment in architectural, industrial, and automotive coatings to provide excellent lightfastness and weather resistance | Added directly during coating formulation; Pigment Green 7 is uniformly dispersed in the binder via grinding and dispersion |
| Printing Inks | Employed in premium printing inks—including gravure, flexographic, and offset inks—to deliver strong color strength and stability | Mixed with resins, solvents, and other components during ink manufacturing; fully ground on three-roll mills to produce finished ink |
| Plastics Processing | Applied as a colorant for thermoplastic resins such as polyolefins, polystyrene, and ABS to achieve consistent coloration | Blended with plastic pellets prior to extrusion or injection molding; uniformly dispersed via melt compounding |
| Rubber Products | Used to color rubber products—including tires and seals—to enhance appearance and durability | Incorporated during rubber compounding; uniformly distributed through internal mixing and open-mill processing |
| Textile Dyeing | Serves as an auxiliary colorant for select textiles, particularly for green-tone finishing of functional fabrics | Applied to fibers via paste dyeing or immersion processes to improve color fastness |
Manufacturing Quality Control of Pigment Geen 7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (by assay) | UV-Vis Spectrophotometry | Quantifies main chromophore absorbance at characteristic wavelength using Beer-Lambert law with reference standard. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Simultaneous multi-element quantification after acid digestion based on element-specific atomic emission intensities. |
| Water Soluble Salts | Conductivity Titration | Measures conductivity of aqueous extract; chloride content determined by argentometric titration with AgNO3. |
| pH of Aqueous Extract | Potentiometric pH Measurement | Determines hydrogen ion activity in suspension using calibrated glass electrode and reference electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes angular scattering pattern of dispersed particles in liquid medium to calculate size distribution. |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry | Measures mass loss after heating at 105 C for 2 h under controlled atmosphere to determine volatile content. |
| Ignition Loss | Gravimetric High-Temperature Calcination | Quantifies volatile and organic matter by mass difference before and after heating at 550 C for 1 h. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Compares reflectance curve and relative color value against certified reference standard in standardized white paste. |
| Oil Absorption | Gum Arabic Paste Method | Determines grams of linseed oil absorbed per 100 g pigment to form a stiff paste using spatula rub-out test. |
| Residue on Sieve (45 um) | Wet Sieving | Measures coarse particle fraction retained on standard 45 um woven wire mesh after dispersion and washing. |
| Bulk Density | Graduated Cylinder Method | Calculates mass per unit volume of freely poured powder into calibrated cylinder without compaction. |
| Specific Surface Area | BET Nitrogen Adsorption | Determines surface area from monolayer nitrogen gas adsorption isotherm using Brunauer-Emmett-Teller theory. |
