Industrial Applications of Pigment Yellow 34
| Industry | Application | Process |
|---|---|---|
| Coatings | Yellow colorant for architectural coatings, industrial coatings, and automotive refinish paints | Ground and dispersed in resin binders (e.g., acrylic, alkyd, polyurethane) to produce color pastes via high-speed dispersion or bead milling |
| Inks | Yellow pigment component for offset, gravure, and flexographic inks | Blended with varnishes (e.g., rosin-modified phenolic resins, polyamide resins) and solvents, then processed into colored inks using three-roll mills |
| Plastics | Coloration of thermoplastic resins including polyvinyl chloride (PVC), polyolefins (PP/PE), and acrylonitrile-butadiene-styrene (ABS) | Compounded with polymer granules and processed via extrusion pelletizing or direct injection molding; heat resistance up to 180–200 °C |
| Rubber | Coloration of light-colored rubber products such as shoe soles, hoses, and gloves | Masterbatched with raw rubber and curatives during internal or open mixing; thermal degradation must be avoided |
Manufacturing Quality Control of Pigment Yellow 34
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Hue | Visual comparison, Colorimeter measurement | Compare the sample with a standard under standard lighting conditions, or use a colorimeter to measure L*a*b* values to assess color consistency. |
| Coloring Strength | Dilution method (comparison with standard) | Mix the sample and standard with white pigment under identical conditions, then compare their coloring intensity via reflectance or visual assessment. |
| Fineness | Scratch fineness gauge method | Apply the pigment dispersion onto a fineness gauge and observe particle deposition to determine the maximum particle size (unit: μm). |
| Dispersion | Grinding dispersion test, Microscopic observation | Evaluate the uniformity of dispersion in the medium after grinding, or use microscopy to assess agglomeration. |
| Heat Resistance | Thermogravimetric Analysis (TGA), Oven aging test | Heat the sample at a specified temperature for a defined duration and observe color changes or weight loss to evaluate thermal stability. |
| Lightfastness | Xenon arc aging test (ISO 11341, etc.) | Use xenon arc lamps for accelerated weathering to assess color change after light exposure (e.g., gray scale rating 1–5). |
| Solvent Resistance | Solvent immersion test | Immerse the sample in solvents such as water, ethanol, and toluene, and observe dissolution, bleeding, or color changes. |
| pH Value | pH meter measurement | Stir and allow a water suspension of the pigment to settle, then measure its acidity or alkalinity using a pH meter to reflect surface treatment status. |
| Volatile Matter (Moisture and Volatiles) | Drying weight loss method (105–110°C) | Weigh a specified amount of sample, dry it at a specified temperature until constant weight, and calculate the percentage of mass loss. |
| Impurity Element Content | Atomic Absorption Spectroscopy (AAS) or ICP-OES | After sample digestion, measure the content of hazardous metal elements such as lead, cadmium, and chromium to ensure compliance with environmental standards (e.g., RoHS). |
| Crystal Structure | X-ray Diffraction (XRD) | Analyze the crystal structure of the pigment to confirm the desired polymorph (e.g., α-phase or β-phase), which influences hue and stability. |
