Packing: It is packed in a dry plastic drum or plywood drum lined with a polyethylene plastic bag, with a net weight of 25kg and 40kg per barrel.
Usage:
Sodium thiocyanate can be used as polyacrylonitrile fiber spinning solvent, color film flushing agent, some plant defoliants, and airport road herbicides.
It is also used in pharmaceutical, printing and dyeing, rubber treatment, black nickel plating, color movies, pesticides and other industries.
It is also used as a mildew-suppressing preservative.
Storage:
This product is easily deliquescent in the air and stored in a cool, dry place.
Should pay attention to moisture, do not pressure, to prevent the lid and broken barrels.
