Product Description
Sodium pyrophosphate(TSPP) Property:
White powder, specific gravity 2.534, melting point 880 ºC, soluble in water, its aqueous solution is alkaline. It can form complex with alkaline earth metal salt. Soluble in acid, insoluble in alcohol and ammonia. The aqueous solution is stable below 70 ºC and hydrolyzed to disodium hydrogen phosphate after boiling. After weathering in dry air, crystal water is lost at 100 ºC. It is easy to absorb moisture and deliquescence in the air.
Sodium pyrophosphate(TSPP) Application:
Totally,mainly used as in industry as detergent auxiliary , paper production to bleach and electroplatingy.It is used for electroplating baths to form complexes together with Fe;For woolen industry as degreasing angent as well as bleaching agent;For Paper industry as decolorizer;For printing and dyeing industry as auxliary agent;For toothpast industry as additive to form colloid together with Dicalcium phosphate;For water treatment industry as water softner;For machanic industry as rust remover.
Technical Specifications(Quality standard HG/T 2968-1999)
Product Packaging:
PE and PP woven bag with inner vacuum treatment. 25kg/ bag, 50kg/ bag, 1000kg/ bag, net weight and pattern can be customized.
