1. Product introduction
The product is white fine amorphous powder, odorless and tasteless. It is used as sulfur removal agent in drilling fluid and is easily soluble in water. When drilling in the formation containing hydrogen sulfide, this product can generate zinc hydroxide film on the drilling tool, slow down the corrosion to the drilling tool and prevent safety accidents. The sulfur removal agent has large specific surface area and large adsorption capacity, and its sulfur removal efficiency is more than 90%.
