Sodium Tripolyphosphate (STPP) | 7758-29-4 ib
Khoom Description
Sodium tripolyphosphate (STP, qee zaum STPP lossis sodium triphosphate lossis TPP) yog ib qho inorganic compound nrog formula Na5P3O10. Sodium triphosphate yog sodium ntsev ntawm polyphosphate penta-anion, uas yog lub hauv paus conjugate ntawm triPhosphoric Acid.Sodium tripolyphosphate yog tsim los ntawm cua sov ib stoichiometric sib tov ntawm Disodium phosphate, Na2HPO4, thiab Monosodium Phosphate, NaH2PO4 ua tib zoo tswj.
Kev siv ntawm Sodium tripolyphosphate kuj suav nrog kev siv nws ua ib qho tshuaj tiv thaiv. Sodium Tripolyphosphate STPP tuaj yeem siv los khaws cov khoom noj xws li nqaij liab, nqaij qaib, thiab nqaij nruab deg, pab lawv khaws lawv cov rhiab thiab ya raws. Cov khoom noj tsiaj thiab tsiaj pub tsiaj tau paub tias yuav kho nrog sodium triphosphate, ua haujlwm tib lub hom phiaj zoo li nws ua hauv tib neeg cov zaub mov.
Daim ntawv thov
1. Sodium tripolyphosphate yog siv rau kev ua cov nqaij, tshuaj detergent formulations, textile dyeing, kuj siv los ua dispersing tus neeg sawv cev, hnyav thiab lwm yam.
2. Nws yog siv los ua dej mos, kuj siv hauv kev lag luam confectionery.
3. Nws yog siv los ua cov chaw nres tsheb fais fab, tsheb thauj mus los, boiler thiab cov chiv cog cov dej txias txias, dej softener. Nws muaj peev xwm muaj zog rau Ca2+ collaterals, ib 100g rau complex 19.5g calcium, thiab vim hais tias SHMP chelation thiab adsorption dispersion rhuav tshem cov txheej txheem ntawm calcium phosphate crystal kev loj hlob, nws tiv thaiv kev tsim ntawm calcium phosphate nplai. Kev noj tshuaj yog 0.5 mg / L, tiv thaiv qhov ntsuas qhov ntsuas siab txog 95% ~ 100%.
4. Hloov kho; emulsifier; tsis muaj; chelate tus neeg sawv cev; stabilizer. Feem ntau rau cov kaus poom nqaij npuas tenderization; cov kaus poom dav taum hauv Yuba softening. Kuj tseem siv tau ua dej mos, pH regulator thiab thickening agent.
5. Nws yog siv rau synergist rau xab npum thiab tiv thaiv bar xab npum grease nag lossis daus. Nws muaj zog emulsification ntawm
lubricating roj thiab roj. Nws tuaj yeem siv los kho tus nqi ntawm pH ntawm tsis siv tshuaj xab npum. Industrial dej softener. Ua ntej
tus neeg sawv cev tanning. Dyeing pab. Xim, kaolin, magnesium oxide, calcium carbonate, xws li muaj nyob rau hauv kev npaj ntawm ncua kev kawm ntawv ntawm dispersant. Drilling av dispersant. Hauv kev lag luam ntawv siv los ua cov tshuaj tiv thaiv roj.
6. Sodium tripolyphosphate yog siv rau detergents. Raws li additives, synergist rau xab npum thiab tiv thaiv bar xab npum crystallization thiab tawg, muaj dej mos dej, pre tanning tus neeg saib xyuas, dyeing auxiliaries, zoo khawb av nkos tswj tus neeg saib xyuas, daim ntawv nrog roj rau tiv thaiv tus neeg saib xyuas, xim, kaolin, magnesium oxide, calcium carbonate, xws li raws li dai ntab ntab kev kho mob zoo
dispersant. Khoom noj khoom haus qib sodium tripolyphosphate raws li ntau yam khoom noj nqaij, zaub mov txhim kho, kev qhia meej ntawm cov dej haus additives.
7. Kev txhim kho zoo los txhim kho cov zaub mov complexed hlau ions, pH tus nqi, nce ionic zog, yog li txhim kho cov zaub mov tsom thiab dej tuav. Kev muab Tuam Tshoj tuaj yeem siv rau cov khoom siv mis nyuj, khoom siv ntses, khoom siv nqaij qaib, ice cream thiab instant noodles, qhov siab tshaj plaws yog 5.0g / kg; nyob rau hauv cov kaus poom, qhov siab tshaj plaws siv kua txiv (saj) dej haus thiab zaub protein haus yog 1.0g / kg.
