Usage:
Tech Grade: For making Monoammonium Phosphate, Diammonium Phosphate, Monopotassium phosphate, Disodium Phosphate, Sodium Tripolyphosphate and Sodium Hexametaphosphate, etc; Also be used in metal surface phosphating compounding electrolytic polishing liquid and chemical polishing liquid.
Food Grade: Acidity agent for acidic drinking liquid, acidity is 7-8 times than that for citric acid, for making many kinds of food grade phosphate, such as Tribasic sodium phosphate, Tribasic potassium phosphate, Triammonium phosphate, Calcium phosphate, Sodium aluminium phosphate, magnesium phosphate etc.
