Umkhiqizi Intengo Enhle I-Sodium Tripolyphosphate CAS：7758-29-4

Intengo Enhle Yomkhiqizi I-Sodium Tripolyphosphate CAS：7758-29-4 Isithombe Esifakiwe

incazelo emfushane:

I-Sodium tripolyphosphate eyaziwa nangokuthi i-pentasodium phosphate, i-sodium pyrometaphosphate, i-STPP, i-pentasodium tripolyphosphate. Ikristalu elimhlophe eliyimpuphu elinoketshezi oluhle, isisindo sama-molecule esingu-367. I-Chemicalbook86, iphuzu lokuncibilika elingu-622 ℃, lincibilika kalula emanzini, futhi isixazululo sayo samanzi siyi-alkaline. Ivame ukusetshenziswa ekudleni njenge-ejenti yokugcina amanzi, i-ejenti yokuthuthukisa ikhwalithi, i-pH regulator, kanye ne-ejenti ye-chelating yensimbi.

Isixazululo samanzi se-Sodium tripolyphosphate si-alkaline kancane (inani le-pH lesisombululo samanzi esingu-1% licishe libe ngu-9.7), futhi sakha ukumiswa (okufana ne-emulsion) emanzini anobubanzi be-pH obungu-4.3-14, okubizwa ngokuthi ukuhlakazeka. I-Sodium tripolyphosphate ingathuthukisa nokuncibilika kwezinhlayiya zamakhemikhali eziwuketshezi neziqinile ezingxeni zamakhemikhali eziwuketshezi (njengamanzi), okwenza isixazululo sibe sobala ngokuphelele futhi sifane nesisombululo sangempela. Lokhu kwaziwa ngokuthi ukuncibilika. Ngenxa yezakhiwo zaso ezihlukile, i-sodium tripolyphosphate isibe yinto eluhlaza ebalulekile nefanele kakhulu ekuhlanzeni izingubo.
