Chaw tsim tshuaj paus tus nqi Xanthan ntawm cov Gub yog: 11138-66-2
Cov yam ntxwv
1) Nrog rau kev nce ntawm shear tus nqi, vim kev rhuav tshem ntawm lub zog colloidal, txo cov tawv nqaij ploj, lub viscosity tuaj yeem rov qab los, yog li nws muaj kev tso pa tawm zoo thiab ua cov khoom. Los ntawm kev siv cov cuab yeej no, xanthan ntawm cov hniav yog ntxiv rau cov kua uas yuav tsum tau ua tuab. Cov kua tsis yog tsuas yog ua kom yooj yim ntws hauv cov txheej txheem thauj mus los, tab sis kuj tuaj yeem rov qab rau cov viscosity uas xav tau tom qab nws tseem. Yog li ntawd, nws tau siv dav hauv kev lag luam dej haus.
2) siab viscosity kua muaj 2% ~ 3% xanthhan ntawm cov hniav ntawm qis concentration, nrog viscosity txog 3 ~ 7pa.s. Nws cov viscosity siab ua rau nws muaj cov kev thov kev cia siab, tab sis tib lub sijhawm, nws coj teeb meem rau kev ua haujlwm tom qab. 0.1% Nacl thiab lwm cov ntsev uas tsis muaj peev xwm txo cov kua nplaum hauv qab no 0.3%, tab sis tuaj yeem nce viscosity ntawm cov kua nplaum tov nrog ntau dua siab.
3) Viscosity ntawm tshav kub-resistant xanthhan ntawm cov pos hniav muaj yuav luag tsis muaj kev hloov pauv hauv qhov kub ntau (- 98 ~ 90 ℃). Lub hauv paus ntawm kev daws teeb meem tsis tau hloov pauv txawm tias nws tau khaws cia ntawm 130 ℃ rau 30 min thiab tom qab ntawd txias. Tom qab ob peb lub khov-lub voj voog mus, lub viscosity ntawm cov kua nplaum tsis hloov. Nyob rau hauv lub xub ntiag ntsev, kev daws tau zoo thermal stability. Yog tias ib qho me me ntawm electrolyte, xws li 0.5% nacl, ntxiv rau ntawm qhov kub thiab txias, lub viscosity ntawm cov kua nplaum tov tuaj yeem ua kom ruaj khov.
4) Lub viscosity ntawm acid resistant thiab alkaline Xanthan ntawm cov pos hniav aqueous daws yog yuav luag ywj pheej ntawm PH. Cov cuab yeej tshwj xeeb no tsis muaj los ntawm lwm cov thickeners xws li carboxymethyl cellulose (cmc). Yog hais tias lub concentration ntawm inorganic acid nyob rau hauv cov kua nplaum tov yog siab dhau, cov kua nplaum yuav tsis ruaj khov; Nyob rau hauv kub, hydrolysis ntawm polysaccharide los ntawm acid yuav tshwm sim, uas yuav ua rau viscosity ntawm cov kua nplaum kom txo qis. Yog tias cov ntsiab lus ntawm Naoh yog ntau dua 12%, xanthan ntawm cov pos hniav yuav yog gelled los yog txawm precipitated. Yog hais tias cov concentration ntawm sodium carbonate yog ntau tshaj 5%, xanthan ntawm cov pos hniav tseem yuav tau gelled.
5) Xanti Enzymatic xanthhan ntawm cov pob txha muaj lub peev xwm tsis yog hydrolyzed los ntawm cov enzymes vim muaj kev thaiv cov nyhuv ntawm sab saw hlau.
6) Kanthan yuav tsum sib xyaw nrog feem ntau siv cov zaub mov txo qis, tshwj xeeb yog cov hmoov txhuv nplej siab, carrageenan thiab carrageenan. Lub viscosity ntawm kev daws teeb meem nyob rau hauv daim ntawv ntawm superposition. Nws qhia tau zoo ua tau zoo nyob rau hauv aqueous kev daws teeb meem nrog ntau cov ntsev. Txawm li cas los xij, qhov tseem ceeb heev hlau ions thiab siab ph yuav ua rau lawv tsis ruaj khov. Ntxiv cov neeg sawv cev muaj peev xwm tiv thaiv qhov tshwm sim ntawm kev tsis sib xws.
7) soluble xanthan ntawm cov pos hniav yog yooj yim soluble hauv dej thiab insoluble hauv cov kuab tshuaj polar xws li cawv thiab Ketone. Nyob rau hauv ntau qhov kub ntau heev, ph thiab ntsev ntau, nws yog ib qho yooj yim kom yaj hauv dej, thiab nws cov kua aqueous tuaj yeem npaj ntawm chav sov. Thaum stirring, huab cua sib xyaw yuav tsum muaj tsawg. Yog xanthan ntawm cov pos hniav muab sib xyaw nrog qee cov dej qhuav, thiab thaum pib siv cov dej, thiab lwm yam, thiab lwm yam. Nws tuaj yeem yaj nyob rau hauv ntau cov organic acids, thiab nws cov kev ua tau zoo yog ruaj khov.
8) Cov kabmob muaj peev xwm ntawm 1% tsis txaus xoom xanthhan ntawm cov pos hniav tov yog 5n / m2, uas yog ib qho kev cuam tshuam zoo tshaj plaws hauv cov zaub mov ntxiv.
9) Dej tuav Xanthan ntawm cov pos hniav muaj dej zoo khaws thiab tshiab-ua kom muaj kev cuam tshuam tshiab rau cov zaub mov.

Cov ntawv thov ntawm Xanthan ntawm qib
1) Hauv kev lag luam roj av roj av, 0.5% xanthhan hniav ntawm cov khoom siv dej tsis muaj zog, yog li cov viscosity ntawm kev siv viscosity yog tsawg heev, uas tau txais kev siv fais fab , thaum nyob rau hauv cov chaw zoo li qub, nws tuaj yeem ua lub luag haujlwm siab, uas ua lub luag haujlwm siab hauv kev tiv thaiv kev tshem tawm ntawm kev tshem tawm ntawm crushed pob zeb sab nraum lub qhov dej.
2) Hauv kev lag luam khoom noj khoom haus, nws zoo dua li cov khoom noj khoom haus tam sim no xws li gelatin, cmc, seaweed cov pos hniav thiab pectin. Ntxiv 0.2% ~ 1% rau cov kua txiv ua rau cov kua txiv muaj cov kua nplaum zoo, thiab kev tswj hwm zoo, thiab kev tswj hwm; Raws li ib qho kev sib ntxiv ntawm cov qhob cij, tuaj yeem ua ncuav hauv qab zib, du, txuag lub sijhawm thiab txo tus nqi; Kev siv ntawm 0.25% hauv cov ncuav ntim zaub, khoom noj uas ua kom zoo thiab qab cov khoom du, thiab txhim kho qhov ruaj khov ntawm cov khoom lag luam kom cua sov thiab khov; Hauv cov khoom noj siv mis, ntxiv 0.1% ~ 0.25% rau cov dej khov tuaj yeem ua si tau lub luag haujlwm zoo heev; Nws muab cov tshuaj vantcosity zoo nyob hauv cov zaub mov kaus poom thiab tuaj yeem hloov ib feem ntawm cov hmoov txhuv nplej siab. Ib feem ntawm xanthan ntawm cov pos hniav tuaj yeem hloov cov hmoov txhuv nplej siab 3-5 feem ntawm cov hmoov txhuv nplej siab. Nyob rau tib lub sijhawm, xanthan ntawm cov pos hniav kuj tau siv dav hauv cov khaub noom, cov khoom ua kom zoo, cov zaub mov khov thiab ua kua roj.
