Appearance: | Colorless and Transparent Liquid |
Packing: In 35kg, 330kg, IBC packing
Property: It is in Colorless, transparent and syrupy liquid or rhombic crystalline; It is odorless
and tastes very sour; its melting point is 42.35 centigrade and when heated to 300 centigrade it will become into meta phosphoric acid; its relative density is 1.834 g/cm3;
it is easily soluble in water and resolves in ethanol; it may irritate human skin to cause
phlogosis and destroy the issue of human body; it shows corrosiveness being heated in
ceramic vessels; it has got hydroscopicity.
Uses: Technical grade phosphoric acid may be used to produce variety of phosphates,
electrolyte treatment liquids or chemical treatment liquids, refractory mortar with phosphoric
acid and inorganic coheretant. It is also used as a catalyst, drying agent and cleaner. In
coating industry it is used as a rust-proof coating for metals; As a acidity regulator and
nutrition agent for yeast food grade phosphoric acid may be applied to flavors, canned food
and light drinks as well as used in wine brewery as a nutrients source for yeast to prevent the
reproduction of useless bacteria
