Properties: white powder, melting point: 60癈, easy soluble
in water and insoluble in alcohol; Dehydrate to become into anhydrous
compound when being heated to 95癈, under the temperature of
190-204癈, transform into sodium acid pyrophosphate, then condensation
polymerize into sodium metaphosphate under the temperature of 204-244癈.
Uses: used in the wastewater treatment(biochemical treatment), boiler
water treating agent, metal electroplating solution, metal surface
purifying agent, feed additive, quality improver, molten-products
additive, etc.
Package: woven bag lined with plastic bag, net weight: 25kg/bag. |
