I-Sodium Tripolyphosphate (STPP) | 7758-29-4
Incazelo Yemikhiqizo
I-sodium tripolyphosphate (STP, ngezinye izikhathi i-STPP noma i-sodium triphosphate noma i-TPP) iyinhlanganisela ye-inorganic enefomula ethi Na5P3O10. I-sodium triphosphate usawoti we-sodium we-polyphosphate penta-anion, okuyisisekelo se-conjugate se-triPhosphoric Acid.I-sodium tripolyphosphate ikhiqizwa ngokushisa ingxube ye-stoichiometric ye-Disodium phosphate, i-Na2HPO4, ne-Monosodium Phosphate, i-NaH2PO4, ngaphansi kwezimo ezilawulwa ngokucophelela.
Ukusetshenziswa kwe-sodium tripolyphosphate kuhlanganisa nokuyisebenzisa njengesivikelo. I-Sodium Tripolyphosphate STPP ingasetshenziselwa ukulondoloza ukudla okufana nenyama ebomvu, izinkukhu, nezilwane zasolwandle, ukuzisiza ukuthi zigcine ububele nomswakama. Ukudla kwezilwane ezifuywayo kanye nokudla kwezilwane kwaziwa ngokuthi kwelashwa nge-sodium triphosphate, kufeza injongo efanayo evamile njengoba kwenza ekudleni kwabantu.
Isicelo
1. I-sodium tripolyphosphate isetshenziselwa ukucutshungulwa kwenyama, ukwakhiwa komshini wokuwasha, ukudaya izindwangu, futhi isetshenziswa njenge-agent ehlakazayo, i-solvent njll.
2. Isetshenziswa njengamanzi athambile, futhi asetshenziswa embonini ye-confectionery.
3. Isetshenziswa njengeziteshi zikagesi, inqola yesitimela, ubhayela kanye nendawo yokupholisa amanzi embonini kamanyolo, okokuthambisa amanzi. Inekhono eliqinile ku-Ca2+ collaterals, nge-100g kuya ku-19.5g ye-calcium eyinkimbinkimbi, futhi ngenxa yokuthi i-SHMP chelation kanye ne-adsorption dispersion yabhubhisa inqubo evamile yokukhula kwekristalu ye-calcium phosphate, ivimbela ukwakheka kwesikali se-calcium phosphate. Umthamo ngu-0.5 mg/L, vimbela ukuthi izinga lokukala lifike ku-95%~100%.
4. Isilungisi; i-emulsifier; isigcinalwazi; i-ejenti ye-chelating; isizinzisi. Ikakhulukazi ekufakweni kwe-ham ekheniwe; ubhontshisi obusemathinini obanzi ekuthambeni kwe-Yuba. Ingasetshenziswa futhi njengamanzi athambile, isilawuli se-pH kanye ne-ejenti yokuqina.
5. Isetshenziselwa i-synergist yensipho nokuvimbela insipho ye-bar grease precipitation kanye nokuqhakaza. Ine-emulsification eqinile ye
amafutha okugcoba namafutha. Ingasetshenziselwa ukulungisa inani le-pH yensipho ye-buffer liquid. Isithambisi samanzi sezimboni. Ngaphambili
i-ejenti yokushuka. Izinsiza zokudaya. Upende, i-kaolin, i-magnesium oxide, i-calcium carbonate, njengezimboni ekulungiseleleni ukumiswa kwe-dispersant. Ukumba i-disperser yodaka. Embonini yephepha esetshenziswa njengama-anti oil agents.
6. I-sodium tripolyphosphate isetshenziselwa okokuhlanza. Njengezithasiselo, i-synergist yensipho nokuvimbela insipho ye-bar crystallization kanye nokuqhakaza, amanzi athambile ezimbonini, i-ejenti yangaphambi kokushuka, izinsiza zokudaya, i-ejenti yokulawula udaka, iphepha elinamafutha ekuvimbeleni i-ejenti, upende, i-kaolin, i-magnesium oxide, i-calcium carbonate, njengokwelashwa okulengayo okuntantayo okusebenzayo
hlakaza. Ibanga lokudla sodium tripolyphosphate njengezinhlobonhlobo zemikhiqizo yenyama, isithuthukisi sokudla, ukucaciswa kwezithasiselo zesiphuzo.
7. Isithuthukisi sekhwalithi sokuthuthukisa ama-ion ensimbi ahlanganiswe nokudla, inani le-pH, ukwandisa amandla e-ionic, ngaleyo ndlela kuthuthukiswe ukugxila kokudla kanye nomthamo wokubamba amanzi. Ukuhlinzekwa kweChina kungasetshenziselwa imikhiqizo yobisi, imikhiqizo yezinhlanzi, imikhiqizo yenkukhu, u-ayisikhilimu nama-noodle asheshayo, umthamo omkhulu ngu-5.0g/kg; ethinini, ukusetshenziswa okuphezulu kwejusi (ukunambitheka) iziphuzo kanye nesiphuzo semifino yemifino yi-1.0g/kg.
