Mtengo Wabwino Wopanga Sodium Tripolyphosphate CAS：7758-29-4

kufotokozera mwachidule:

Sodium tripolyphosphate imadziwikanso kuti pentasodium phosphate, sodium pyrometaphosphate, STPP, pentasodium tripolyphosphate. Kristalo woyera wonga ufa wokhala ndi madzi abwino, kulemera kwa maselo a 367. Chemicalbook86, malo osungunuka a 622 ℃, amasungunuka mosavuta m'madzi, ndipo yankho lake lamadzi ndi la alkaline. Amagwiritsidwa ntchito kwambiri muzakudya ngati chosungira madzi, chothandizira kukonza khalidwe, chowongolera pH, komanso chothandizira chelating chachitsulo.

Madzi a sodium tripolyphosphate ndi a alkaline pang'ono (pH ya 1% yamadzi a sodium ndi pafupifupi 9.7), ndipo imapanga suspension (yofanana ndi emulsion) m'madzi okhala ndi pH ya 4.3-14, yomwe imatchedwa dispersion. Sodium tripolyphosphate imathanso kukulitsa kusungunuka kwa tinthu tamadzimadzi ndi tating'onoting'ono ta mankhwala m'madzi (monga madzi), zomwe zimapangitsa kuti yankho likhale lowonekera bwino komanso lofanana ndi yankho lenileni. Izi zimadziwika kuti solubilization. Chifukwa cha mawonekedwe ake apadera, sodium tripolyphosphate yakhala chinthu chofunikira komanso choyenera kwambiri mu sopo wochapira zovala.
