Packaging and Storage
zinc carbonate is packaged in multi-wall, paper sacks; packing container sizes will vary based on local area of purchase.
Store in a dry location away from sources of heat or ignition, and minimize dust.
Application & Dosage
Under operating conditions, zinc carbonate reacts with sulfides to form zinc sulfide (ZnS), which has an extremely low solubility in water (0.0096 g/mL). Drilling fluids should not be acidified; otherwise, hydrogen sulfide could be liberated.
zinc carbonate is effective as a scavenger at the pH levels found in drilling fluids. It is recommended that a pH above 10 be maintainedb whenever H2S is expected. This high alkalinity converts the dangerous H2S gas to less toxic bisulfide (HS-) and sulfide (S2-) ions. The alkaline pH (>10) allows an extra margin of safety.
