Txhua hnub tshuaj lom neeg qib hydroxypropyl methyl cellulose

Cov tshuaj txhua hnub hydroxypropyl cellulose yog hluavtaws polymer npaj los ntawm kev hloov kho tshuaj lom neeg ntawm cov khoom siv raw. Cellulose ether yog ib tug derivative ntawm ntuj cellulose, cellulose ntau lawm, nws cov khoom siv hluav taws xob sib txawv thiab cov cellulose, lub ntuj polymer compound. Vim tias muaj tshwj xeeb ntawm cov qauv ntuj cellulose, cellulose nws tus kheej tsis muaj peev xwm hnov ​​cov neeg sawv cev. Txawm li cas los xij, tom qab kev kho mob ntawm ofeed of tus neeg sawv cev ntawm thiab hauv cov pab pawg molecular raug tso tawm rau hauv alkali cellulose nrog kev siv hluav taws xob. Tom qab cov tshuaj tiv thaiv ntawm kev pom tus neeg sawv cev, pab pawg -Oh tau hloov mus rau hauv pab pawg ether ether.

Txhua hnub tshuaj qib kev tshwj xeeb 200 txhiab viscosity Instant HydroxyPropy yog xim dawb lossis tsw qab, tsis muaj kuab, tsis muaj tshuaj lom. Soluble hauv kev sib tov ntawm dej txias thiab organic kuab tshuaj los tsim cov tshuaj pleev pob tshab. Kev daws kev ywg dej muaj cov haujlwm saum npoo av, siab transparency, muaj zog ruaj khov, solubility hauv dej tsis cuam tshuam los ntawm Ph. Thickening thiab antifleithip muaj txiaj ntsig hauv zawv plaub hau thiab lub cev ntxuav, kom txuag dej thiab ua yeeb yaj kiab zoo tsim rau cov plaub hau thiab tawv nqaij. Nrog rau cov kev nce ntxiv ntawm cov ntaub ntawv raw, cellulose (tshuaj tiv thaiv tuab) tuaj yeem siv hauv cov tshuaj zawv plaub hau thiab lub cev ntxuav tau muaj peev xwm txo cov nqi thiab ua tiav cov txiaj ntsig xav tau.

1. Cov yam ntxwv thiab cov txiaj ntsig ntawm cov tshuaj kawm txhua hnub cellulose hpmc:

1, kev txob txob qis, kub thiab sib deev;

2, muaj ntau qhov kev ruaj khov, hauv tus nqi ntawm tus nqi ntawm 3-11 ntau tuaj yeem ua kom nws ruaj khov;

3. Kev nce qib ntawm kev rov ua dua;

4. Nce npuas, ruaj khov npuas, txhim kho cov tawv nqaij lwj;

5. Txhim kho txoj kab ke ntawm cov kab ke.

2 Txhua hnub tsim tshuaj cellulose hpmc daim ntawv thov tau txais:

Siv nyob rau hauv zawv zawv plaub hau, lub cev ntxuav, ntxuav, pleev tshuaj, cov khoom siv txhuam, tshuaj txhuam hniav, dej tshuaj txhuam hniav, dej, khoom ua si npuas dej.

3 lub luag haujlwm ntawm cov tshuaj txhua hnub cellulose hpmc:

Hauv kev thov cov tshuaj pleev ib ce, nws yog tsuas yog siv rau cov khoom siv ua tuab, kev ua yeeb yam zoo, cov yeeb yaj kiab muaj kuab, cov yeeb yaj kiab siab, cov khoom siv viscosity ntau, cov khoom siv viscosity ntau dua thiab kev tsim zaj duab xis thiab zaj duab xis tsim.

4 Txhua hnub tshuaj xyuas cellulose hpmc technology:

HydroxyPropy kasthyl fiber ntau los hloov kho cov tshuaj viscosity yog feem ntau 100 txhiab, 15 txhiab, muaj li peb mus rau tsib txhiab leej.
