Product Description
ALIAS: Sodium Rhodanide, Sodium Sulfocyanate, Sodium Rhodanate, Sodium Isocyanate, sodium Isothiocyanate, Thiocyanic Acid, Sodium Salt
Properties: Sodium thiocyanate is a white orthorhombic crystal or powder. The relative density is 1.735g/cm3. The melting point is 287°C. It is easy to deliquescence in the air, and produces toxic gas when it encounters acid. Soluble in water, ethanol, acetone and other solvents. The aqueous solution is neutral, and it will form blood-colored ferric thiocyanate with iron salt, it will not react with ferrous salt, it will produce yellow sodium bisulfate with concentrated sulfuric acid, it will react with cobalt salt to form dark blue cobalt thiocyanide, and it will react with silver salt or Copper salts react to form white silver thiocyanide precipitates or black copper thiocyanide precipitates.
Sodium thiocyanate is an important chemical raw material, which can be used as metal detection agent, cement grinding aid, diffusion agent, dyeing agent, solvent, analytical reagent, pickling corrosion inhibitor, preservative and other products in medicine, pesticide, printing and dyeing, chemistry, textile, electroplating, rubber, building materials and other fields, with a broad application space.
Application
Genaral: Mainly used in sectors of pharmaceuticals, pesticide, synthetic fibre, electroplating, photography, accelerator for cement etc.
Fibre industriy : as spinning solvent for polyacrylonitrile.
Architecture industriy: hardening accelerator for cement and concrete mixes.
Pesticide: raw material for the production of a number of herbicides and fungicides.
Pharmaceuticals: raw material for the production of a number of pharmaceutical products.
Sodium thiocyanate obviously promoted the hydration degree in the hydration acceleration stage, and the promotion effect was obvious with the increase of the dosage, and the promotion effect was relatively more lasting, which was conducive to improving the early strength of cement.
Sodium thiocyanate as the early strength component of concrete is beneficial to maintain the working performance of concrete.
