tlhaloso e khutšoanyane:

Sodium tripolyphosphate e tsejoang hape e le pentasodium phosphate, sodium pyrometaphosphate, STPP, pentasodium tripolyphosphate. Kristale e tšoeu e phofo e nang le mokelikeli o motle, boima ba limolek'hule ba 367. Chemicalbook86, ntlha ea ho qhibiliha ea 622 ℃, e qhibilihang habonolo metsing, 'me tharollo ea eona ea metsi ke alkaline. E sebelisoa hangata lijong e le moemeli oa ho boloka metsi, moemeli oa ntlafatso ea boleng, molaoli oa pH, le moemeli oa chelating oa tšepe.

Tharollo ea metsi ea sodium tripolyphosphate e na le alkaline e fokolang (boleng ba pH ba tharollo ea metsi ea 1% ke hoo e ka bang 9.7), 'me e etsa suspension (e tšoanang le emulsion) ka metsing ka pH ea 4.3-14, e bitsoang dispersion. Sodium tripolyphosphate e ka boela ea ntlafatsa ho qhibiliha ha likaroloana tsa lik'hemik'hale tse metsi le tse tiileng ka har'a mecha ea metsi (joalo ka metsi), e leng se etsang hore tharollo e bonaletse ka botlalo 'me e tšoane le tharollo ea sebele. Sena se tsejoa e le ho qhibiliha. Ka lebaka la thepa ea eona e ikhethang, sodium tripolyphosphate e fetohile thepa ea bohlokoa le e loketseng ea sesepa sa ho hlatsoa liaparo.
