Kev kho mob kuj tau txais txiaj ntsig zoo heev los ntawm cov khoom tshwj xeeb ntawm xanthan cov pos hniav.Nws tus cwj pwm rheological tso cai rau kev tswj cov tshuaj tso tawm, ua rau nws muaj qhov zoo tshaj plaws hauv cov tshuaj formulations.Tsis tas li ntawd, nws cov biocompatibility thiab biodegradability ua rau nws haum rau ntau yam kev kho mob daim ntawv thov xws li lub qhov txhab hnav khaub ncaws thiab tswj kev xa tshuaj.
Tshaj li cov kev lag luam uas tau hais los saum no, xanthan cov pos hniav pom nws txoj hauv kev mus rau ntau lwm cov haujlwm, suav nrog kev lag luam tshuaj txhua hnub.Los ntawm cov tshuaj txhuam hniav mus rau cov tshuaj zawv plaub hau, xanthan cov pos hniav pab txhawb rau qhov xav tau kev ntxhib los mos thiab ruaj khov ntawm cov khoom no.
Kev lag luam viability ntawm xanthan cov pos hniav yog unparalleled thaum piv rau lwm cov microbial polysaccharides.Nws cov kev siv ntau yam thiab cov khoom tshwj xeeb tau ua rau nws mus rau cov khoom xyaw rau suav tsis txheeb manufacturers.Tsis muaj lwm yam microbial polysaccharide tuaj yeem phim nws cov kev siv ntau yam thiab kev ua tau zoo.
Ntim: 25kg / hnab
Cia:Xanthan cov pos hniav tuaj yeem siv dav hauv cov roj rho tawm, tshuaj, khoom noj, tshuaj, kev ua liaj ua teb, dyes, ceramics, ntawv, textile, tshuaj pleev ib ce, kev tsim kho thiab kev tsim khoom tawg thiab lwm yam ntau tshaj 20 kev lag luam hauv txog 100 yam khoom.Txhawm rau kom yooj yim khaws cia thiab kev thauj mus los, nws feem ntau ua rau cov khoom qhuav.Nws ziab muaj ntau txoj kev kho mob: lub tshuab nqus tsev ziab, nruas ziab, tshuaj tsuag kom qhuav, fluidized txaj kom qhuav thiab cua kom qhuav.Vim tias nws yog cov khoom kub-rhiab heev, nws tsis tuaj yeem tiv taus qhov kub thiab txias rau lub sijhawm ntev, yog li kev siv cov tshuaj tsuag kom qhuav yuav ua rau nws tsis tshua muaj soluble.Txawm hais tias lub thermal efficiency ntawm lub nruas ziab yog siab, cov cuab yeej siv tshuab yog qhov nyuaj dua, thiab nws nyuaj rau kev ua tiav rau kev lag luam loj.Fluidized txaj kom qhuav nrog inert spheres, vim yog ob qho tib si txhim kho cua sov thiab huab hwm coj hloov pauv thiab kev sib tsoo thiab crushing zog, cov khoom tuav lub sij hawm kuj luv luv, yog li nws yog tsim rau ziab tshav kub-sensitive viscous cov ntaub ntawv xws li xanthan gum.
Kev ceev faj rau kev siv:
1. Thaum npaj xanthan cov pos hniav, yog tias cov dispersion tsis txaus, cov hlab ntsha yuav tshwm sim.Ntxiv nrog rau kev nplawm tag nrho, nws tuaj yeem ua ntej sib xyaw nrog lwm cov ntaub ntawv raw, thiab tom qab ntawd ntxiv rau hauv dej thaum nplawm.Yog hais tias nws tseem nyuaj rau disperse, ib tug miscible hnyav nrog dej ntxiv, xws li ib tug me me ntawm ethanol.
2. Xanthan gum yog ib qho anionic polysaccharide, uas tuaj yeem siv ua ke nrog lwm yam anionic lossis non-ionic, tab sis tsis tuaj yeem sib xyaw nrog cationic tshuaj.Nws cov tshuaj muaj kev sib raug zoo thiab ruaj khov rau feem ntau cov ntsev.Ntxiv cov electrolytes xws li sodium chloride thiab potassium chloride tuaj yeem txhim kho nws cov viscosity thiab stability.Calcium, magnesium thiab lwm cov ntsev bivalent pom muaj cov teebmeem zoo sib xws ntawm lawv cov viscosity.Thaum cov ntsev concentration siab tshaj 0.1%, qhov pom viscosity tau mus txog.Cov ntsev ntsev ntau dhau tsis txhim kho kev ruaj ntseg ntawm xanthan cov pos hniav, thiab tsis cuam tshuam rau nws cov rheology, tsuas yog pH> Thaum 10 teev tsaus ntuj (cov khoom noj khoom haus tsis tshua muaj tshwm sim), cov ntsev ntawm cov ntsev bivalent qhia txog kev nyiam ua gels.Nyob rau hauv acidic los yog nruab nrab tej yam kev mob, nws trivalent hlau ntsev xws li txhuas los yog hlau daim ntawv gels.Cov ntsiab lus siab ntawm monovalent hlau ntsev tiv thaiv gelation.
3. Xanthan cov pos hniav tuaj yeem ua ke nrog ntau cov khoom lag luam thickeners, xws li cellulose derivatives, starch, pectin, dextrin, alginate, carrageenan, thiab lwm yam. Thaum ua ke nrog galactomannan, nws muaj kev sib koom ua ke ntawm kev nce viscosity.
Hauv kev xaus, xanthan cov pos hniav yog qhov zoo kawg nkaus ntawm kev tshawb fawb niaj hnub no.Nws lub peev xwm tshwj xeeb raws li tus neeg sawv cev thickening, tus neeg sawv cev ncua kev kawm, emulsifier, thiab stabilizer tau hloov pauv txoj kev ntau yam kev lag luam.Los ntawm cov khoom noj uas peb noj mus rau cov tshuaj uas peb cia siab rau, xanthan cov pos hniav cuam tshuam yog qhov tsis lees paub.Nws txoj kev lag luam muaj koob meej thiab daim ntawv thov dav ua rau nws muaj zog tiag tiag hauv ntiaj teb cov khoom xyaw.Siv cov khawv koob ntawm xanthan cov pos hniav thiab qhib nws lub peev xwm hauv koj cov khoom niaj hnub no.
