Microcrystalline cellulose yog dab tsi?

Microcrystalline cellulose (MCC), feem ntau yog tsim los ntawm β- Cov kab ncaj nraim polysaccharide ua ke nrog 1,4-glucoside daim ntawv cog lus [1] yog cov hmoov dawb, tsis muaj ntxhiab thiab saj tsis qab crystalline hmoov uas muaj qhov zoo heev luv luv pas nrig-puab los yog hmoov-puab porous hais. uas tuaj yeem ntws dawb thiab hydrolyze natural cellulose mus rau qhov txwv degree ntawm polymerization (LODP) tom qab dilute acid hydrolysis.
Feem ntau cov nroj tsuag fibers, microcrystalline cellulose suav txog li 70%, thiab lwm yam 30% yog amorphous. Microcrystalline cellulose yog dav siv hauv tshuaj, tshuaj pleev ib ce, zaub mov thiab lwm yam lag luam. Qhov sib txawv particle loj thiab cov ntsiab lus dej muaj cov yam ntxwv sib txawv thiab kev siv ntau yam.

Cov microcrystalline cellulose yog tau los ntawm cov nroj tsuag cellulose tom qab hydrolysis, thiab cov txheej txheem kwv yees yog: hydrolysis ntawm dilute inorganic acid tov α- Cellulose, nyob rau hauv α- Cellulose tuaj yeem tsim los ntawm cellulose pulp ntawm cellulosic nroj tsuag. Lub hydrolyzed cellulose yog lim, purified, thiab cov slurry yog tshuaj tsuag qhuav los ua cov khoom ntxeem tau nrog cov khoom siv dav dav.

Kev siv ua haujlwm: adsorbent; Suspension agent; thinners rau cov ntsiav tshuaj thiab tshuaj ntsiav; Disintegrator rau cov ntsiav tshuaj
Khoom qeb: cellulose | tshuaj excipients, zaub mov additives
Cov khoom siv: dawb los yog yuav luag dawb hmoov, tsw tsw thiab saj tsis qab. Cov khoom no yog insoluble hauv dej, ethanol, acetone los yog toluene.
CAS Nr .: 9004-34-6

Kev ua haujlwm ntawm microcrystalline cellulose

Microcrystalline cellulose tuaj yeem ruaj khov ua npuas dej thiab emulsion, tshwj xeeb tshaj yog thaum ua haujlwm kub; Tsim gel nrog tshuaj pleev kom zoo nkauj; Txhim kho qhov kub tsis kam ntawm pectin thiab starch gel; Txhim kho adhesion; Hloov cov roj thiab roj thiab tswj cov dej khov siv lead ua kev loj hlob. Yog vim li cas vim li cas microcrystalline cellulose tuaj yeem ua kom ruaj khov emulsion thiab ua npuas ncauj yog tias microcrystalline cellulose yog adsorbed ntawm lub interface thiab ntxiv dag zog rau thaj tsam ntawm lub ntsej muag lub ntsej muag. Microcrystalline cellulose yog ib qho khoom muaj nyob rau hauv cov mis nyuj muaj roj tsawg thiab lwm yam khoom qab zib khov.

Hauv kev lag luam tshuaj, microcrystalline cellulose feem ntau yog siv los ua adsorbent, ncua kev pab cuam, diluent thiab disintegrant. Microcrystalline cellulose yog siv dav hauv kev npaj tshuaj, feem ntau yog diluent thiab nplaum hauv cov ntsiav tshuaj hauv qhov ncauj thiab tshuaj ntsiav. Nws tuaj yeem siv tsis tau tsuas yog rau ntub granulation tab sis kuj rau qhuav ncaj qha ntsiav tshuaj nias. Nws kuj muaj qee yam lubricating thiab disintegrating los, uas yog heev pab tau nyob rau hauv kev npaj cov ntsiav tshuaj. Nws muaj qhov zoo hauv qab no tshaj cov hmoov txhuv nplej siab los yog hmoov txhuv nplej siab derivatives:
(1) Nws yog ib qho yooj yim rau disintegrate, uas yog, cov tshuaj yog yooj yim rau disintegrate tom qab nkag mus rau hauv lub plab thiab absorbed los ntawm lub cev.
(2) Nws tsis yooj yim rau mildew vim cellulose yog β Hom A qabzib teeb tsa, thaum hmoov txhuv nplej siab yog rau α Hom teeb tsa. Feem ntau, amylase tsis tua cellulose.
(3) Cellulose tsis absorbed los ntawm tib neeg lub cev, thiab nws tsis yooj yim rau reacted rau cov tshuaj loaded, yog li nws muaj kev nyab xeeb dua. Nws qhov tsis zoo yog tias tus nqi yog nyob rau sab siab.

Kev siv ntawm microcrystalline cellulose

Hauv kev lag luam khoom noj khoom haus, microcrystalline cellulose yog cov khoom noj khoom haus ua haujlwm zoo - cov khoom noj fiber ntau, uas yog cov khoom noj khoom haus zoo tshaj plaws. Nws tuaj yeem tswj tau qhov ruaj khov ntawm emulsification thiab ua npuas ncauj; Nws tuaj yeem tswj tau qhov ruaj khov ntawm qhov kub thiab txias thiab txhim kho kev ruaj ntseg ntawm cov kua, thiab tseem tuaj yeem siv los ua cov khoom noj khoom haus thiab cov thickener. Ntau cov khoom noj nqaij, cov zaub mov khov sai thiab cov dej khov nab kuab ntxiv.
Hauv kev lag luam tshuaj pleev ib ce, microcrystalline cellulose yog siv los ua cov khoom sib xyaw rau ntau yam tshuaj pleev ib ce, kho tawv nqaij thiab cov khoom tu, nrog rau kev tsim cov tshuaj ntxuav tes. Nws ua ke cov dej num ntawm kev sau, thickening thiab emulsification, thiab muaj peev xwm emulsification zoo rau cov khoom oily.
