Technical details and manufacturing context for Industrial Grade Sodium Percarbonate Bleaching Agent

Definition
Sodium percarbonate is a chemical compound with formula 2Na2CO3·3H2O2, serving as a solid source of hydrogen peroxide. This industrial-grade material provides controlled release of active oxygen for bleaching applications across multiple industries. It offers superior stability compared to liquid hydrogen peroxide while maintaining strong oxidizing properties. The compound dissolves in water to release hydrogen peroxide and sodium carbonate, making it effective for both bleaching and cleaning functions. This directory entry describes a material intended for industrial use, not a specific commercial product. The listed parameters, such as active oxygen content (13.0–14.5%), bulk density (0.9–1.1 g/cm³), particle size distribution (0.2–1.5 mesh), moisture content (≤0.5%), pH value (10.0–11.0), storage temperature maximum (40°C), active oxygen content stability (≥95% after 6 months at 25°C), solubility in water (≥150 g/L at 20°C), heavy metal content (≤10 mg/kg), iron content (≤5 mg/kg), and appearance (white free-flowing powder), are typical reference ranges based on standard GB/T 27804. These values must be verified with the legal manufacturer or supplier for the specific grade and application. The material is used in industries such as textiles, paper, detergents, and water treatment, where controlled oxidation is required. It is important to confirm compatibility with process conditions and safety requirements. The product is not certified or compliant solely by listing a standard; the standard serves as a procurement reference. Always consult the supplier for detailed specifications and safety data sheets.
Working Principle
When dissolved in water, sodium percarbonate releases hydrogen peroxide, which decomposes to produce oxygen radicals. These radicals oxidize and bleach organic compounds, breaking down chromophores and stains. The release is controlled, providing a steady supply of active oxygen. The byproduct, sodium carbonate, acts as a mild alkali, enhancing cleaning efficiency. This mechanism makes it effective for bleaching textiles, paper pulp, and in detergent formulations.
