Kev siv rau kev lag luam thiab kev noj tau sodium tripolyphosphate
Sodium tripolyphosphate yog ib hom inorganic compound, dawb crystalline hmoov, soluble hauv dej, alkaline kua, yog amorphous dej-soluble linear polyphosphate. Sodium tripolyphosphate muaj cov haujlwm ntawm chelating, suspending, dispersing, gelatinizing, emulsifying, pH buffering, thiab lwm yam. Nws tuaj yeem siv ua cov khoom ntxiv tseem ceeb ntawm cov tshuaj ntxuav tes, cov dej ua kom mos rau kev lag luam, cov neeg sawv cev pretanning tawv, cov neeg sawv cev dyeing, organic synthesis catalyst, cov khoom noj khoom haus additive, thiab lwm yam. Yog li, cov kev siv ntau ntawm kev lag luam thiab noj tau sodium tripolyphosphate yog dab tsi?
Kev siv ntau ntawm sodium tripolyphosphate:
1. Feem ntau siv ua ib qho khoom siv rau cov tshuaj ntxuav tes, rau cov tshuaj ntxuav xab npum sib xyaw thiab tiv thaiv kom tsis txhob muaj nag thiab frosting ntawm cov roj xab npum. Nws muaj cov nyhuv emulsification muaj zog rau cov roj lubricating thiab cov rog, thiab tuaj yeem siv los kho tus nqi PH ntawm cov kua xab npum buffer.
Sodium tripolyphosphate yog ib qho tseem ceeb thiab zoo heev rau kev pabcuam ntxuav khaub ncaws, thiab nws cov haujlwm tseem ceeb tuaj yeem sau ua ke raws li hauv qab no.
① Chelation ntawm cov hlau ions
Feem ntau cov dej ntxhua khaub ncaws txhua hnub muaj cov hlau ions (feem ntau yog Ca2+, Mg2+). Thaum lub sijhawm ntxuav khaub ncaws, lawv yuav tsim cov ntsev hlau uas tsis yaj tau nrog cov khoom siv hauv xab npum lossis tshuaj ntxuav khaub ncaws, yog li tsis yog tsuas yog siv tshuaj ntxuav khaub ncaws ntau ntxiv xwb, tab sis kuj ua rau cov ntaub tom qab ntxuav muaj xim grey tsaus tsis zoo. Sodium tripolyphosphate muaj cov khoom zoo heev ntawm kev chelating hlau ions, uas tuaj yeem tshem tawm cov teebmeem tsis zoo ntawm cov hlau ions no.
② Txhim kho lub luag haujlwm ntawm gel dissolution, emulsification thiab dispersion
Av feem ntau muaj cov kua qaub ntawm tib neeg (feem ntau yog cov protein thiab cov rog), tab sis kuj muaj xuab zeb thiab hmoov av los ntawm lub ntiaj teb sab nraud. Txawm li cas los xij, sodium tripolyphosphate muaj cov nyhuv ntawm kev o thiab solubilization ntawm cov protein thiab ua lub luag haujlwm ntawm cov kua colloidal. Rau cov rog, nws tuaj yeem txhawb kev emulsification. Nws muaj cov nyhuv dispersive suspension rau cov khoom khov.
③ cov nyhuv buffering
Sodium tripolyphosphate muaj cov nyhuv alkaline buffering loj, yog li ntawd tus nqi pH ntawm cov tshuaj ntxuav tau khaws cia ntawm kwv yees li 9.4, uas yog qhov zoo rau kev tshem tawm cov av acid.
④ Lub luag haujlwm ntawm kev tiv thaiv kev ua caking
Cov tshuaj ntxuav hmoov uas ua los ntawm cov tshuaj muaj cov yam ntxwv hygroscopic, xws li khaws cia rau hauv qhov chaw uas muaj av noo ntau, yuav ua rau tawv tawv. Cov tshuaj ntxuav uas tawv tawv tsis yooj yim siv. Cov hexahydrate uas tsim los ntawm sodium tripolyphosphate tom qab nqus dej muaj cov yam ntxwv ntawm qhuav. Thaum muaj ntau sodium tripolyphosphate hauv cov mis tshuaj ntxuav, nws tuaj yeem tiv thaiv qhov tshwm sim tawv tawv uas tshwm sim los ntawm kev nqus dej thiab tswj cov duab qhuav thiab granular ntawm cov tshuaj ntxuav.
2. Kev ntxuav dej thiab ua kom mos: sodium tripolyphosphate chelates cov hlau ions nrog cov hlau ions hauv cov kua Ca2 +, Mg2 +, Cu2 +, Fe2 +, thiab lwm yam, los tsim cov chelates soluble, yog li txo qhov nyuaj, thiab siv dav hauv kev ntxuav dej thiab ua kom mos.
3. Tshuaj ua kom tawv nqaij mos: ua kom zaub thiab txiv hmab txiv ntoo tawv nqaij mos sai, ua kom lub sijhawm ua noj luv dua thiab txhim kho qhov nrawm ntawm pectin.
4. Tus neeg sawv cev tiv thaiv kev hloov xim, tshuaj tiv thaiv: tuaj yeem txhawb kev lwj ntawm cov vitamin C thiab cov xim ploj mus, kev hloov xim, tuaj yeem tiv thaiv kev lwj ntawm nqaij, nqaij qaib, ntses, kom ntev lub sijhawm khaws cia zaub mov.
5. Tus neeg sawv cev tiv thaiv kev dawb, deodorant: txhim kho cov nyhuv dawb, thiab tuaj yeem tshem tawm cov ntxhiab tsw hauv cov hlau ions.
6. Tshuaj tua kab mob thiab kab mob bacteriostatic: tiv thaiv kev loj hlob ntawm cov kab mob me me, yog li nws ua lub luag haujlwm antiseptic thiab bacteriostatic.
7. Emulsifier, pigment mincemeat dispersant, anti-delamination agent, thickening agent: disperse lossis stabilize qhov kev ncua ntawm cov tshuaj insoluble hauv dej kom tiv thaiv kev lo thiab condensation ntawm qhov kev ncua.
8. Muaj zog buffer thiab preservative: Tswj thiab tswj kom muaj PH ruaj khov, uas tuaj yeem ua rau cov zaub mov saj qab dua. Tswj acidity, acid rate.
9. Tus neeg sawv cev khaws dej, tus neeg sawv cev mos, tus neeg sawv cev mos: nws muaj cov nyhuv zoo dua rau cov protein thiab globulin, yog li nws tuaj yeem ua rau cov khoom nqaij noo thiab khaws dej, txhim kho kev nkag mus ntawm dej, txhawb kev ua kom cov khoom noj mos thiab txhim kho qhov zoo ntawm cov khoom noj, thiab tswj cov saj zoo ntawm cov khoom noj.
10. Tus neeg sawv cev tiv thaiv kev sib sau ua ke: Hauv cov khoom noj mis nyuj, nws tuaj yeem tiv thaiv kev sib sau ua ke ntawm cov mis nyuj thaum cua sov, thiab tiv thaiv kev sib cais ntawm cov protein mis nyuj thiab cov rog dej.
11. Xim, kaolin, magnesium oxide, calcium carbonate thiab lwm yam kev npaj ua lag luam ntawm kev ncua raws li dispersant.
12. Kev siv tshuaj zas xim.
13. Cov tshuaj dispersant rau cov av nkos.
14. Kev lag luam ntawv siv los ua tus neeg sawv cev tiv thaiv roj.
15. Ua ib tug neeg sawv cev degumming hauv kev tsim cov khoom siv ceramic.
16. Tus neeg sawv cev ua ntej tannery.
17. Tus neeg sawv cev ua kom dej kub hauv kev lag luam.
