Soo saaraha Qiimaha Wanaagsan Sodium Tripolyphosphate CAS: 7758-29-4

sharaxaad gaaban:

Sodium tripolyphosphate sidoo kale loo yaqaan pentasodium phosphate, sodium pyrometaphosphate, STPP, pentasodium tripolyphosphate.Crystal budo cad oo leh dareere wanaagsan, qaraabo miisaanka molecular ee 367.Chemicalbook86, barta dhalaalka ee 622 ℃, si fudud ugu milmi biyaha, iyo xal aqueous waa alkaline.Inta badan loo isticmaalo cuntada sida wakiilka biyaha haynta, wakiilka hagaajinta tayada, nidaamiyaha pH, iyo wakiilka birta.

Sodium tripolyphosphate aqueous xal waa alkaline daciif ah (qiimaha pH ee 1% xal aqueous ah oo ku saabsan 9.7), oo waxay samaysaa ganaax (la mid ah emulsion ah) biyo leh pH kala duwan ee 4.3-14, taas oo loo yaqaan kala firdhiso.Sodium tripolyphosphate waxay sidoo kale wanaajin kartaa milanka dareeraha iyo walxaha kiimikada adag ee dareeraha ah (sida biyaha) warbaahinta, taas oo ka dhigaysa xalka gebi ahaanba hufan oo u eg xal dhab ah.Tan waxaa loo yaqaana solubilization.Sababo la xiriira sifooyinkeeda gaarka ah, sodium tripolyphosphate waxay noqotay shay muhiim ah oo ku habboon saabuunta dharka lagu dhaqdo.
