Neutralization thiab rinsing: Lub cellulose tom qab acid hydrolysis yuav tsum tau neutralized thiab ces yaug dua kom tshem tawm cov residual acid thiab lwm yam by-products.
Qhuav thiab pulverization: Lub purified cellulose yog qhuav thiab mechanically pulverized kom tau microcrystalline cellulose hmoov.
Lub cev thiab tshuaj muaj zog ntawm microcrystalline cellulose
Microcrystalline cellulose yog cov hmoov dawb los yog dawb, tsis qab thiab tsw ntxhiab nrog cov yam ntxwv tseem ceeb hauv qab no:
High crystallinity: Cov qauv molecular ntawm microcrystalline cellulose muaj ntau cov crystalline cheeb tsam nrog siab crystallinity, uas ua rau nws zoo txhua yam muaj zog thiab ruaj khov.
Zoo heev fluidity thiab compressibility: Cov microcrystalline cellulose hais muaj zog binding quab yuam thiab muaj peev xwm tsim cov ntsiav tshuaj ntom ntom thaum lub sij hawm ntsiav tshuaj, uas yog dav siv nyob rau hauv kev lag luam kws tshuaj.
Kev nqus dej siab: Microcrystalline cellulose muaj peev xwm nqus dej zoo thiab tuaj yeem siv ua cov thickener, stabilizer, thiab lwm yam hauv cov khoom noj thiab tshuaj pleev ib ce.
Chemical inertness: Microcrystalline cellulose tsis ua rau muaj tshuaj lom neeg, muaj tshuaj lom neeg ruaj khov, thiab tuaj yeem tswj tau nws qhov kev ua tau zoo hauv ntau qhov chaw tshuaj lom neeg.
Siv thaj chaw ntawm microcrystalline cellulose
Kev lag luam kws tshuaj
Hauv kev lag luam kws tshuaj, microcrystalline cellulose yog dav siv los ua cov khoom siv ncaj qha compression thiab disintegrant rau cov ntsiav tshuaj. Vim nws qhov kev ua tau zoo compression thiab fluidity, microcrystalline cellulose tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm cov ntsiav tshuaj. Tsis tas li ntawd, microcrystalline cellulose kuj tuaj yeem siv los ua cov tshuaj ntsiav tshuaj los pab cov tshuaj kom sib npaug thiab tswj tus nqi tso tawm.
Kev lag luam zaub mov
Hauv kev lag luam khoom noj khoom haus, microcrystalline cellulose yog siv los ua cov khoom siv ntxiv, feem ntau yog cov thickener, stabilizer, anti-caking tus neeg saib xyuas thiab cov khoom noj fiber ntau ntxiv. Kev nqus dej siab thiab kev ruaj ntseg zoo heev ntawm microcrystalline cellulose ua rau nws siv dav hauv ntau yam khoom noj, xws li cov khoom noj siv mis, cov khoom noj nqaij, cov zaub mov ci, thiab lwm yam. Tsis tas li ntawd, microcrystalline cellulose kuj tseem siv tau rau hauv cov khoom noj uas tsis muaj calories thiab cov khoom hnyav li. ib qho tsis-calorie muab tub lim kom nce satiety ntawm cov zaub mov.
Kev lag luam tshuaj pleev ib ce
Hauv kev lag luam tshuaj pleev ib ce, microcrystalline cellulose feem ntau yog siv los ua cov thickener thiab stabilizer nyob rau hauv cov khoom xws li tshuaj pleev ib ce, cream, gels, thiab lwm yam. Nws cov khoom zoo thiab cov khoom zoo dispersion pab kom microcrystalline cellulose ho txhim kho cov kev ntxhib los mos thiab siv kev paub ntawm cov khoom. Tsis tas li ntawd, kev nqus dej ntawm microcrystalline cellulose tuaj yeem txhim kho cov nyhuv moisturizing ntawm cov tshuaj pleev ib ce.
Lwm daim ntawv thov
Microcrystalline cellulose kuj tau siv dav hauv lwm qhov chaw, xws li hauv kev lag luam papermaking ua daim ntawv txhim kho, hauv kev lag luam textile ua kev hloov kho rau textile fibers, thiab hauv tsev cov ntaub ntawv ua cov thickener thiab stabilizer. Nws versatility thiab kev nyab xeeb ua rau nws yog ib tug tseem ceeb neeg uas ua ntawv nyob rau hauv ntau yam kev lag luam teb.
Kev nyab xeeb ntawm microcrystalline cellulose
Microcrystalline cellulose yog suav tias yog khoom noj khoom haus thiab tshuaj ntxiv. Nws txoj kev nyab xeeb tau lees paub los ntawm ntau yam kev tshawb fawb toxicological thiab kev sim tshuaj. Ntawm cov koob tshuaj uas tsim nyog, microcrystalline cellulose yuav tsis muaj teebmeem rau tib neeg lub cev. Txawm li cas los xij, raws li kev noj zaub mov fiber ntau, kev noj ntau dhau yuav ua rau mob plab tsis zoo, xws li tsam plab, raws plab, thiab lwm yam. Yog li ntawd, thaum siv microcrystalline cellulose, nws cov kev siv yuav tsum tau tswj raws li kev thov tshwj xeeb scenarios thiab cov khoom yuav tsum tau ua.
Microcrystalline cellulose yog ntau yam thiab dav siv cellulose derivative. Nws lub cev zoo heev thiab tshuaj lom neeg ua rau nws ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam xws li tshuaj, khoom noj thiab tshuaj pleev ib ce. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev nthuav dav ntawm daim ntawv thov kev lag luam, microcrystalline cellulose xav tias yuav ua rau muaj peev xwm ntau dua thiab muaj txiaj ntsig kev lag luam yav tom ntej.
