Product Description
Key Benefits of Our Product:
- High Dispersibility: Our micro-fine powder ensures that even in high-speed mixing, it disperses evenly without creating “white spots” in the rubber matrix.
- Sulfur Scavenging: In the oil and gas sector, it reacts rapidly with (Hydrogen Sulfide), making it an essential desulfurizer for drilling muds.
- Low Impurities: We strictly control Lead (Pb) and Cadmium (Cd) levels, making our product suitable for sensitive applications like veterinary feed additives or pharmaceutical skin protectants.

Applications
- Rubber Industry:
- Primary vulcanization activator for transparent, translucent, and light-colored rubber products.
- Used in latex products (gloves, tubing) as a cross-linking agent.
- Oil & Gas (Oilfield Grade):
- Acts as a fast-acting desulfurizer in water-based drilling fluids. It effectively removes H2S, protecting equipment from corrosion and ensuring worker safety.
- Agriculture & Animal Feed:
- Used as a trace element supplement for Zinc deficiency in livestock.
- Personal Care & Cosmetics:
- Found in skin-protectant powders and calamine lotions due to its mild antiseptic and soothing properties.
- Rayon Production:
- Used in the manufacturing of rayon fibers and as a chemical raw material for the production of other zinc salts.
Storage Conditions
- Avoid Acids: Zinc Carbonate reacts vigorously with acids. Never store it near acidic chemicals.
- Moisture Control: While it is relatively stable, the powder is prone to clumping if exposed to high humidity. Store in a cool, dry, and ventilated warehouse.
- Seal Integrity: Always keep the inner PE bag sealed. If left open, the powder may absorb atmospheric moisture, affecting its flowability in automatic dosing systems.
Safety Precautions
- Dust Inhalation: Like any fine powder, prolonged inhalation can irritate the respiratory tract. Workers should wear dust masks (N95 or equivalent) during hopper loading.
- Skin/Eye Contact: Generally non-toxic and non-irritating, but it is a drying agent. Rinse with water if contact occurs.
- Environment: While Zinc is a necessary nutrient, large spills in waterways can be toxic to aquatic life. Ensure spills are contained and disposed of according to local environmental regulations.

FAQ - Technical & Supply Chain
-
Q:
How is Zinc Carbonate (CAS 3486-35-9) chemically distinguished from Basic Zinc Carbonate?
A: Zinc Carbonate (CAS 3486-35-9) is the neutral carbonate species ( 𝑍 𝑛 𝐶 𝑂 3). It is chemically distinct from Basic Zinc Carbonate (Zinc carbonate hydroxide, CAS 5263-02-5), which contains hydroxide groups. Industrial verification relies on zinc content analysis (typically ~52% for neutral vs. higher for basic) and stoichiometry checks to ensure the correct material is selected for specific sulfur scavenging or pharmaceutical applications. -
Q:
What is the primary industrial application of Zinc Carbonate in the energy sector?
A: In the oil and gas industry, this material is intended for use as a sulfide scavenger. It is added to drilling muds and fluids to react with and neutralize hazardous hydrogen sulfide (H2S) gas, converting it into insoluble zinc sulfide to ensure operational safety and prevent equipment corrosion.
