Dab tsi yog cov lus txhais ntawm fiber ntau, cellulose, thiab cellulose ether thiab dab tsi yog qhov sib txawv?

Putty hmoov feem ntau yog tsim cov tshuaj yeeb yaj kiab (cov hmoov txhuv nplej siab, thiab lwm yam hauv qab, cov hmoov txhuv nplej siab, thiab siv cov khoom siv tshuaj tiv thaiv kab mob zoo, thiab siv ntau yam khoom siv tshuaj lom neeg rau koj ib leeg.

Fiber:

Fiber (Asmeskas: fiber; Askiv: fiber ntau) yog hais txog cov tshuaj yeeb yaj kiab los ntawm nruam los yog txiav txim siab. Xws li cog fiber ntau, tsiaj plaub hau, ua kom sov, hluavtaws fiber ntau, thiab lwm yam.

Cellulose:

Cellulose yog mactromolecular polysaccharide muaj cov piam thaj thiab yog cov txheej txheem tseem ceeb ntawm cov nroj tsuag ntawm tes. Nyob rau hauv chav tsev kub, cellulose yog tsis yog dab tsi nyob rau hauv dej los yog nyob rau hauv tej organic cov kuab tshuaj. Cov ntsiab lus cellulose ntawm paj rwb yog ze rau 100%, ua nws cov purest ntuj ntawm cellulose. Nyob rau hauv cov ntoo dav dav, cov nyiaj cellulose rau 40-50%, thiab muaj 10-30%

Qhov sib txawv ntawm cellulose (txoj cai) thiab cov hmoov txhuv nplej siab (sab laug):

Feem ntau hais lus, ob lub hnub qub thiab cellulose yog macromolecular polysaccharides, thiab cov mis roj ntsha tuaj yeem qhia raws li (C6h10o5) n. Qhov hnyav molecular ntawm cellulose loj dua tias cov hmoov txhuv nplej siab, thiab cellulose tuaj yeem decomposed los tsim cov hmoov txhuv nplej siab. Cellulose yog d-flucose thiab β-1,4 glycoside mycyromolecular polysaccharide muaj kev sib xyaw ntawm Bonds, thaum cov hmoov txhuv nplej siab tsim los ntawm daim ntawv cog lus α-1,4 glycosidic. Cellulose feem ntau tsis ceged, tab sis cov hmoov txhuv nplej siab yog branched los ntawm 1,6 glycosidic bonds. Cellulose yog tsis zoo soluble hauv dej, thaum cov hmoov txhuv nplej siab yog cov dej kub. Cellulose yog insensitive rau amloase thiab tsis tig xiav thaum raug Iodine.

Cellulose ether:

Lub npe lus Askiv lub npe Ethaet yog cellulose ether, uas yog ib tug qauv ovher ua los ntawm cov qauv ntawm cellulose. Nws yog cov khoom lag luam ntawm cov tshuaj lom neeg cov tshuaj tiv thaiv ntawm cellulose (cog) nrog tus neeg sawv cev ntawm lub nroog. Raws li cov qauv tshuaj cais tawm ntawm cov hloov chaw tom qab etherification tom qab etherification, nws tuaj yeem faib ua anionic, cationic thiab cov tsis muaj kev ua neej. Ua raws li cov neeg sawv cev ntawm lub nroog uas siv, ua cellulose cellulose, cellulropyl cellulose, cellulropyl hydulose, cellulropy cellulose thiab cellulose cellulose thiab cov cellulose, etc. hauv kev tsim kho Kev lag luam, Cellulose ether tseem tuaj yeem hu ua cellulose, uas yog lub npe tsis xwm yeem, thiab nws hu ua cellulose (lossis ether) kom raug.

Thickening txheej ntawm cellulose ether thickener:

Cellulose ether thickeners tsis yog-ionic thickeners uas thicken tsuas yog los ntawm kev haus dej thiab entanglement ntawm molecules.

Lub polymer saw ntawm cellulose tau yooj yim los tsim hydrogen nyiaj nrog dej hauv dej, thiab hydrogen bond ua rau nws muaj cov dej num ntau thiab inter-molecular anentanglement.

Thaum lub cellulose ether thickener ntxiv rau cov xim looj kua yas, ua rau nws cov khoom siv dawb, ua rau nws muaj ntau qhov chaw dawb, ua rau cov pigments, fillers thiab kua yas;

Nyob rau tib lub sijhawm, lub cellulose ither molecular charts yog interters network qauv, thiab cov pig, thiab cov kua txiv thiab cov kua txiv thiab cov kua yas thiab tsis tuaj yeem ntws dawb.

Raws li ob qho teebmeem no, lub viscosity ntawm lub kaw lus raug txhim kho! Ua tiav cov nyhuv tuab uas peb xav tau!
