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

incazelo emfushane:

I-sodium tripolyphosphate eyaziwa nangokuthi i-pentasodium phosphate, i-sodium pyrometaphosphate, i-STPP, i-pentasodium tripolyphosphate. Ikristalu eyimpuphu emhlophe enoketshezi oluhle, isisindo samangqamuzana esihlobene esingu-367.Chemicalbook86, indawo encibilikayo engu-622 ℃, incibilika kalula emanzini, futhi isixazululo sayo esinamanzi sine-alkali. Okuvame ukusetshenziswa ekudleni njenge-ejenti yokugcina amanzi, i-ejenti yokuthuthukisa ikhwalithi, isilawuli se-pH, ne-ejenti ye-metal chelating.

Isixazululo se-sodium tripolyphosphate aqueous sine-alkaline ebuthakathaka (inani le-pH yesisombululo esinamanzi esingu-1% silinganiselwa ku-9.7), futhi sakha ukumiswa (okufana ne-emulsion) emanzini ngebanga le-pH lika-4.3-14, elibizwa ngokuthi i-dispersion. I-sodium tripolyphosphate ingaphinde ithuthukise ukuncibilika kwezinhlayiya zamakhemikhali eziwuketshezi neziqinile kuketshezi (njengamanzi) emithonjeni yezokuxhumana, kwenze isixazululo sibe sobala ngokuphelele futhi sifane nesixazululo sangempela. Lokhu kwaziwa ngokuthi i-solubilization. Ngenxa yezakhiwo zayo ezihlukile, i-sodium tripolyphosphate isiphenduke into esetshenziswayo ebalulekile futhi efanelekile kumshini wokuwasha izingubo.
