Sodium Pyrophosphate | 7722-88-5
Khoom Description
Product Description: Sodium Pyrophosphate yog ib qho inorganic compound.Nws yooj yim nqus dej hauv huab cua thiab delixoscopic, soluble hauv dej, insoluble hauv ethanol thiab lwm cov kuab tshuaj organic. Nws muaj peev xwm ua kom muaj zog nrog Cu2 +, Fe3 +, Mn2 + thiab lwm yam hlau ions, thiab cov tshuaj aqueous ruaj khov hauv qab 70 Degree Celsius, thiab nws tuaj yeem hydrolyzed rau disodium hydrogen phosphate los ntawm boiling.
Daim ntawv thov: Siv raws li dispersant thiab emulsifier nyob rau hauv tshuaj ntau lawm thiab Siv raws li tshuaj txhuam hniav additive nyob rau hauv niaj hnub tshuaj kev lag luam, nws muaj peev xwm tsim colloid nrog calcium hydrogen phosphate thiab ua si lub luag hauj lwm stabilizing. Nws tseem tuaj yeem siv rau hauv cov tshuaj tua hluavtaws thiab tsim cov tshuaj zawv plaub hau thiab lwm yam khoom.
Cia:Cov khoom yuav tsum tau muab cia rau hauv qhov chaw ntxoov ntxoo thiab txias. Tsis txhob cia nws raug tshav ntuj. Kev ua tau zoo yuav tsis cuam tshuam nrog damp.
Standards ua:International Standard.
