Cellulose yog cov khoom tseem ceeb ntawm cov nroj tsuag cell phab ntsa. Nws yog qhov feem ntau nthuav dav thiab ntau tshaj polysaccharide nyob rau hauv cov xwm, accounting rau ntau tshaj 50% ntawm cov ntsiab lus carbon nyob rau hauv cov nroj tsuag lub nceeg vaj. Ntawm lawv, paj rwb muaj cov ntsiab lus cellulose ze li ntawm 100%, uas yog lub ntuj ntshiab tshaj plaws ntawm cellulose. Hauv cov ntoo, cellulose suav rau 40-50%, thiab muaj 10-30% hemicellulose thiab 20-30% lignin.
Cellulose ether yog cov ntsiab lus dav dav rau cov khoom siv cellulose derivatives tsim los ntawm ntuj cellulose ua raw khoom, los ntawm cov txheej txheem tshuaj thiab lub cev xws li alkalization, etherification cov tshuaj tiv thaiv, thiab kev kho tom qab hauv qee yam mob. Nws yog ib yam khoom tsim thaum cov pab pawg hydroxyl ntawm cov cellulose molecular saw yog ib feem los yog tag nrho hloov los ntawm ether pawg. Cellulose macromolecules muaj intrachain thiab interchain hydrogen bonds, thiab nyuaj rau yaj hauv dej thiab yuav luag tag nrho cov kuab tshuaj organic. Txawm li cas los xij, tom qab etherification thiab kev taw qhia ntawm ether pawg, hydrophilicity tuaj yeem txhim kho thiab solubility hauv dej thiab cov kuab tshuaj organic tuaj yeem txhim kho tau zoo. Cov qauv molecular ntawm cellulose ether yog qhia hauv daim duab hauv qab no:
Cellulose ether yog lub npe hu ua "kev lag luam MSG" thiab muaj cov khoom zoo xws li cov tshuaj thickening, zoo solubility ntawm dej, ncua kev kawm ntawv los yog latex stability, tiv thaiv colloid nyhuv, film-forming, thiab dej tuav. Nws yog dav siv nyob rau hauv ntau lub teb xws li cov ntaub ntawv hauv tsev, tshuaj, khoom noj, textiles, tshuaj niaj hnub, roj extraction, mining, papermaking, polymerization, honeycomb ceramics, aerospace thiab tshiab zog roj teeb. Cellulose ether muaj qhov zoo ntawm daim ntawv thov dav, kev siv me me, kev hloov pauv zoo, thiab kev phooj ywg ib puag ncig. Nws tuaj yeem txhim kho thiab ua kom zoo dua cov khoom lag luam hauv thaj tsam ntawm nws qhov sib ntxiv, uas yog qhov tsim nyog rau kev txhim kho kev siv cov peev txheej thiab cov khoom muaj nqis ntxiv. Nws yog indispensable ib puag ncig tus phooj ywg additive nyob rau hauv tag nrho cov teb ntawm lub teb chaws kev khwv nyiaj txiag.
