application
characteristic: NaSCN, white orthorhombic crystal, soluble in water, ethanol, acetone; relative density is 1.735. melted into
about 287. It decomposes under the action of heat and light to produce toxic fumes of sulfur oxides, nitrogen oxides and cyanides. Reacts violently with acids, strong bases and strong oxidizing agents
usage:
1. General: Mainly used in medicine, pesticide, synthetic fiber, electroplating, photography, cement accelerator and other industries.
2. Fiber industry:As a spinning solvent for polyacrylonitrile.
3. Construction industry: Hardening accelerator for cement and concrete mixtures.
4. Pesticides: Raw material used in the production of various herbicides and fungicides.
5. Drugs: Raw material used in the production of various pharmaceutical products.
storage: Please put in a sealed bag. Store in a cool, dry, ventilated place to prevent deliquescence. Store separately from acids, alkalis and oxidizing agents.
