    As an accredited Zinc Bisulfite factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.

    Packing & Storage
    Packing Zinc Bisulfite is packaged in a 25 kg white HDPE drum with secure lid, labeled with product details and hazard warnings.
    Shipping Zinc bisulfite should be shipped in tightly sealed containers, protected from moisture and incompatible substances. Transport under cool, dry conditions, ensuring proper labeling according to chemical regulations. Use corrosion-resistant packaging and comply with relevant safety and handling standards to prevent leaks or accidental exposure during transit. Handle with appropriate personal protective equipment.
    Storage Zinc bisulfite should be stored in a tightly sealed container, away from moisture, heat, and incompatible substances such as strong oxidizers or acids. Keep it in a cool, well-ventilated area, protected from direct sunlight. Ensure proper labeling and keep the storage area dry to prevent hydrolysis or decomposition. Follow all relevant safety and chemical storage regulations.
    Application of Zinc Bisulfite

    Purity 98%: Zinc Bisulfite with 98% purity is used in industrial water treatment processes, where it enhances heavy metal precipitation efficiency.

    Particle Size <10 μm: Zinc Bisulfite with particle size less than 10 μm is used in paper manufacturing, where it ensures uniform cellulose bleaching and increased paper brightness.

    Aqueous Solution 40% w/w: Zinc Bisulfite as a 40% aqueous solution is applied in textile dyeing, where it improves color fixation and reduces processing time.

    Stability Temperature up to 120°C: Zinc Bisulfite stable up to 120°C is utilized in closed-loop cooling systems, where it prevents scale formation under elevated thermal loads.

    Molecular Weight 179.5 g/mol: Zinc Bisulfite with a molecular weight of 179.5 g/mol is incorporated in specialty chemical synthesis, where it provides predictable stoichiometry for controlled reaction outcomes.

    Low Heavy Metal Content (<0.05%): Zinc Bisulfite with low heavy metal content is used in food-grade applications, where it meets safety standards and minimizes contamination risk.

    Solution pH 4.5–5.0: Zinc Bisulfite solution with pH 4.5–5.0 is added in photographic processing, where it stabilizes developer chemicals and prolongs bath lifespan.

    Granule Form, Free-Flowing: Zinc Bisulfite in free-flowing granule form is used in water-soluble fertilizer blends, where it allows for homogeneous nutrient distribution.

    High Solubility (>95% in water): Zinc Bisulfite with solubility over 95% in water is selected for agrochemical formulations, where it enables rapid and complete dissolution during application.

    Bulk Density 1.9 g/cm³: Zinc Bisulfite with a bulk density of 1.9 g/cm³ is incorporated in catalyst manufacturing, where it ensures precise volumetric dosing and optimal reactivity.
