Cellulose yog lub tseem ceeb tivthaiv ntawm cov nroj tsuag ntawm tes, thiab yog feem ntau tshaj plaws polysaccharide nyob rau hauv cov xwm txheej, suav rau ntau tshaj 50 cov ntsiab lus hauv cov nroj tsuag. Ntawm lawv, cov ntsiab lus cellulose ntawm paj rwb yog ze rau 100%, uas yog lub cellulose ntuj cellulose hauv paus. Nyob rau hauv cov ntoo dav dav, cov nyiaj cellulose rau 40-50%, thiab muaj 10-30% Cellulose ether yog ib lo lus dav dav rau ntau yam ntawm derivatives tau los ntawm cov khoom siv ntawm lub ntsej muag los ntawm etherification. Nws yog cov khoom tsim tom qab pawg hydroxyl ntawm cellulose macromolecules yog ib nrab lossis pab pawg ether. Muaj kev sib tw hauv cov saw thiab cuam tshuam hydrogen hydrogen hauv maculome, uas yog qhov nyuaj rau yaj hydrophilicity thiab nce nce solubility hauv dej thiab cov kuab tshuaj organic. Cov khoom siv solubility.
Cellulose ether muaj lub koob npe nrov ntawm "Industrial Monosodium Glutamate". Nws muaj cov khoom huv zoo li kev daws teeb meem thickening, solubility zoo, ncua lossis yas ruaj khov, ua yeeb yaj kiab, thiab cov tshuaj nplaum. Nws tseem tsis muaj tshuaj lom thiab tsis muaj tshuaj, thiab yog siv cov tshuaj, cov khoom noj, cov ntawv nyeem, roj av txhua hnub thiab ntau lwm cov teb. Cellulose ether muaj qhov zoo siv, kev siv me me, kev hloov kho zoo, thiab kev ua phooj ywg ib puag ncig. Nws tuaj yeem txhim kho thiab ua kom zoo dua cov khoom lag luam hauv kev sib ntxiv, uas yog qhov ua kom zoo rau kev txhim kho kev ua haujlwm siv tau thiab cov khoom ntxiv. Ib puag ncig cov phooj ywg ib puag ncig uas tseem ceeb hauv ntau thaj teb.
Raws li ionization ntawm cellulose etherituents ether, hom sib txawv, cellulose ether tuaj yeem faib rau ntau hom. Raws li cov sib txawv ntawm cov neeg hloov pauv, cov kws ua haujlwm cellulose tuaj yeem muab faib ua ib qho kev ua tau lwm tus thiab kev sib xyaw. Raws li solubility, cellulose ether tuaj yeem faib ua dej-soluble thiab dej insoluble khoom. Raws li kev ionization, nws tuaj yeem faib ua Ionic, tsis yog-ionic thiab khoom sib xyaw. Ntawm cov dej-soluble cellulos neeg muaj kev hais ua, tsis muaj-ionic cellulose kev ua kom sov xws li hpmc tau zoo dua li cov tshuaj uas muaj kev pab cuam Ionic (CMC).
Cellulose txhim kho ntau npaum li cas hauv kev lag luam?
Cellulose ether yog tsim los ntawm rwb rwb rwb rwb los ntawm kev ua alkalization, etherical, etherification thiab lwm cov kauj ruam. Cov txheej txheem ntau lawm ntawm cov qeb Tshuaj HPMC thiab zaub mov Qeb HPMC yog qhov zoo ib yam. Piv nrog lub tsev cov khoom siv-cellulose ether, cov txheej txheem HPMC thiab yuav tsum tau ua kom muaj cov khoom siv ntau lawm, thiab yuav tsum tau huv cov cuab yeej siv thiab cov chaw tsim khoom.
Raws li cov ntaub ntawv muab los ntawm Tuam Tshoj cellulose muaj peev xwm kev lag luam kev lag luam, xws li cov tuam tsev ntau lawm, thiab lwm yam ntawm National Power muaj peev xwm ntau lawm. Muaj ntau ntau lwm cov me me tsis-ionic cellulose etherers cov muaj peev xwm nrog lub muaj peev xwm ntau lawm tsawg dua 4,000 tons. Tsuas yog rau ob peb tus neeg lag luam, feem ntau ntawm lawv tsim cov khoom siv qib cellulose muaj peev xwm muaj peev xwm ntau yam txog 100,000 tons ib xyoos. Vim tias tsis muaj lub zog nyiaj txiag, ntau tus neeg lag luam me me tsis ua raws li kev kho dej hauv ib puag ncig thiab tso pa tawm kom txo cov nqi tsim khoom. Raws li lub teb chaws thiab tag nrho haiv neeg them ntau dua thiab ntau dua rau kev tiv thaiv ib puag ncig, cov lag luam uas tsis tuaj yeem ua haujlwm ib puag ncig yuav maj mam maj mam kaw lossis txo cov ntau lawm. Lub sijhawm ntawd, kev xav ntawm kuv lub teb chaws lub cellulose ether kev lag luam yuav nce ntxiv.
Kev tiv thaiv ib puag ncig ib puag ncig tau dhau los ua ntau thiab ntau txoj kev tiv thaiv, thiab nruj tiv thaiv kev tiv thaiv ib puag ncig thiab kev nqis peev hauv cov txheej txheem ntawm cellulose ether. Kev ntsuas kev tiv thaiv ib puag ncig cov txheej txheem kev nce nqi ntau lawm ntawm cov lag luam thiab tseem ua cov kev tiv thaiv kev tiv thaiv ib puag ncig. Cov lag luam uas tsis tuaj yeem ua tiav cov cai tiv thaiv ib puag ncig yuav maj mam kaw lossis txo cov txheej txheem kom tau raws li kev tiv thaiv ib puag ncig. Raws li lub tuam txhab kev lag luam, cov lag luam uas maj mam txo cov khoom siv ntawm cov khoom siv ntawm ib puag ncig ntawm cov khoom lag luam ether ethere, uas ua rau kev nthuav dav ntawm kev nthuav dav ntawm kev lag luam.
Raws li ntawm cellulose ether, nws txuas ntxiv mus rau qhov kawg thiab muaj txiaj ntsig zoo ntxiv
