Detailed Manufacturing Process of Bromo Indigo Granules

The production of Bromo Indigo granular products is a sophisticated multi-stage chemical synthesis and physical processing endeavor, adhering to stringent quality control standards like ISO 9001. Our process ensures a high-purity, consistent, and user-friendly product.

Process Flow:

1. Raw Material Sourcing & Preparation: Key precursors, including indoxyl and bromine compounds, are meticulously sourced for purity. Incoming materials undergo rigorous quality checks to meet internal specifications, preventing downstream contamination or quality issues.
2. Chemical Synthesis (Bromination & Oxidation): The core of Bromo Indigo production involves the bromination of indigo, followed by controlled oxidation. This complex reaction is performed under precisely monitored conditions of temperature, pH, and reaction time within specialized reactors to ensure high yield and purity of the desired dye chromophore, C.I. Vat Blue 5. Advanced catalytic systems may be employed to optimize efficiency.
3. Purification & Filtration: Post-synthesis, the crude dye is subjected to multiple purification steps. This typically involves washing, filtration, and potentially re-crystallization to remove unreacted raw materials, by-products, and inorganic salts. Techniques like membrane filtration or pressure filtration are employed to separate the pure dye cake.
4. Standardization: To ensure consistent tinctorial strength and shade, the purified dye is standardized. This involves adjusting the concentration of the pure dye with inert diluents or other additives. Spectrophotometric analysis is crucial at this stage to match established color standards and maintain lot-to-lot consistency.
5. Granulation: This critical step transforms the dye into its granular form. Common methods include:
   • Spray Drying: A liquid dispersion of the dye is atomized into a hot drying chamber, forming fine, spherical granules as the water evaporates.
   • Fluid Bed Granulation: Dye particles are suspended in an upward stream of air while a binder solution is sprayed, causing particles to agglomerate into granules.
   • Extrusion: A paste-like dye mixture is forced through a die, forming strands that are then cut into uniform granules.
   The chosen method ensures optimal granule size, density, and friability for superior handling and dispersion.
6. Drying & Sizing: Granules are dried to a specific moisture content to ensure stability and prevent caking. Subsequently, they are sieved to achieve a narrow particle size distribution, ensuring consistent performance in dyeing operations.
7. Final Quality Control & Packaging: The finished granular product undergoes comprehensive testing, including color strength, shade, solubility, dispersion rate, moisture content, and fastness properties (e.g., light, wash, perspiration fastness) according to ISO 105 series standards. Only products meeting rigorous specifications are packaged in moisture-proof container111s, ready for dispatch by صادرکنندگان گرانول آبی نیلی.

Target Industries & Advantages:

Our Bromo Indigo granular products primarily serve the textile industry, particularly for cotton, linen, and cellulosic blends. Key advantages in these application scenarios include:
