Microcrystalline cellulose

Microcrystalline cellulose yog purified, ib nrab depolymerized cellulose, ib tug dawb, tsis muaj ntxhiab, tasteless crystalline hmoov muaj xws li ntxeem tau hais. Nyob rau hauv tag nrho cov nroj tsuag fibers, nws suav txog li 70 feem pua, thiab cov seem 30 feem pua ​​yog amorphous. Siv dav hauv kev lag luam 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 daim ntawv thov ntau yam.

Microcrystalline cellulose feem ntau yog siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug adsorbent, ncua kev kawm ntawv additive, diluent, disintegrant, thiab kuj yog lug siv nyob rau hauv pharmaceuticals, feem ntau nyob rau hauv lub qhov ncauj ntsiav tshuaj thiab tsiav tshuaj, raws li ib tug diluent thiab binder. Nws tuaj yeem siv tsis tau tsuas yog rau ntub granulation, tab sis kuj rau qhuav ncaj qha ntsiav tshuaj compression, thiab nws muaj ib tug tej yam lubricity thiab disintegration nyhuv, uas yog heev pab tau nyob rau hauv cov ntsiav tshuaj ua. Vim muaj hydrogen bonds ntawm microcrystalline cellulose molecules, hydrogen bonds bonds nyob rau hauv siab, yog li nws compresses zoo thiab feem ntau yog siv los ua ib tug khi. Cov khoom no kuj tseem siv tau los ua cov tshuaj tiv thaiv coagulant, emulsifier, dispersant, binder, xovxwm ntsiav tshuaj thiab ntaub txhim kho. Nws kuj tseem siv tau los ua cov cua sov stabilizer thiab cov xov xwm kom qhuav sai. Nws tseem tuaj yeem siv los ua cov khoom noj fiber ntau hauv cov khoom noj tshwj xeeb xws li cov khoom noj uas tsis muaj calorie tsawg thiab cov rog tsawg. Hauv kev lag luam khaub ncaws, nws muaj peb qhov teebmeem: ua kom dawb, softening fabrics, tshem tawm cov av, thiab nws muaj txiaj ntsig zoo ntawm cov cellulosic fibers xws li paj rwb thiab paj rwb.
