Industrial Applications of ASTRAZON ORANGE R
| Industry | Application | Process |
|---|---|---|
| Textile Dyeing and Printing | Dyeing and printing of natural fibers including cotton, linen, silk, and wool | Applied in direct dyeing, mordant dyeing, or as a component in dye mixtures; typically used under acidic or neutral conditions |
| Leather Industry | Leather coloring | Applied via immersion dyeing or finishing processes to enhance color intensity and uniformity |
| Paper Manufacturing | Paper dyeing (specialty papers) | Incorporated into pulp or applied during surface sizing to improve color performance |
| Ink Manufacturing | Colorant in solvent-based inks | Blended with resins and solvents to formulate packaging and printing inks |
| Plastic Coloring | Coloring of thermoplastic plastics such as polyvinyl chloride (PVC) and polystyrene (PS) | Pre-blended with plastic granules prior to melt extrusion or injection molding |
Manufacturing Quality Control of ASTRAZON ORANGE R
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by separation on reversed-phase column and UV detection at characteristic wavelength (e.g., 480 nm). |
| Related Substances (Impurities) | HPLC-UV | Separates and detects structurally related impurities (e.g., isomers, intermediates) using gradient elution and UV detection. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration based on iodine–sulfur dioxide redox reaction. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Quantifies trace heavy metals after acid digestion by mass spectrometric detection of elemental isotopes. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual residue. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode. |
| Organic Volatile Impurities (e.g., residual solvents) | GC-FID | Identifies and quantifies volatile organic residues (e.g., methanol, acetone) using capillary column separation and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension by analyzing angular variation of laser light scattering. |
| Color Strength (Tinting Strength) | UV-Vis Spectrophotometry | Compares absorbance of sample solution against certified reference standard at λmax to assess dyeing performance. |
| Chloride Ion Content | Ion Chromatography (IC) | Separates and quantifies chloride anions using suppressed conductivity detection after anion-exchange column separation. |
