Dab tsi yog cov khoom ntawm cellulose muaj kev ua phem?

Cellulose Cov neeg muaj kev hais ua yog ib pawg-soluble polymers tau los ntawm cellulose, lub ntuj polymer pom nyob hauv cov phab ntsa ntawm tes ntawm cov nroj tsuag. Cov txheej txheem uas muaj kev cuam tshuam tau hloov kho los ntawm cov txheej txheem tshuaj lom neeg los yaum cov khoom tshwj xeeb uas ua rau lawv muaj txiaj ntsig hauv cov ntawv thov ntau yam. Qee lub cellulos cellulose muaj xws li methyl cellulose (MC), HydroxyPropyl cellulose (HECTORSHROPYETYFREET (HEC), thiab hydroxypropyl methyl cellulose (HPMC). Cov yam ntxwv ntawm cellulose cov neeg ua kom raug cuam tshuam los ntawm lawv cov qauv tshuaj thiab qib hloov chaw. Nov yog qee qhov chaw dav dav ntawm cov neeg ua haujlwm ntawm cellulos:

1. Dej Solubility:

• Cellulose muaj kev hais ua tau zoo ua rau cov dej solubility zoo heev, ua rau lawv haum rau kev siv hauv cov dej-ua cov qauv. Cov cuab yeej no tso cai rau kev suav nrog kev sib raug zoo ua kua, xws li cov xim tha xim, cov nplaum, thiab kws tshuaj.

2. Zaj duab xis-tsim muaj peev xwm:

• Ntau ntau tus neeg hais txog muaj peev xwm ua cov yeeb yaj kiab thaum daws cov polymer yog qhuav. Cov cuab yeej no yog pab tau tshwj xeeb rau cov ntawv thov xws li txheej ci, qhov twg tsim ntawm cov yeeb yaj kiab tiv thaiv yog qhov xav tau.

3. Thickening thiab rheology hloov kho:

• Cellulose muaj kev hais ua haujlwm tau zoo siv cov thickeners thiab rheology modifiers. Lawv tuaj yeem nce viscosity ntawm kev daws teeb meem thiab muab kev tswj hwm ntawm cov khoom ntws ntawm cov kua tsim ua kua. Cov cuab yeej no yog qhov tseem ceeb hauv cov khoom lag luam zoo li cov xim tha xim, cov nplaum, thiab cov khoom saib xyuas tus kheej.

4. Adhesion thiab Binding:

• Cov neeg hais ua neeg hais ua haujlwm ntawm cellulose ua rau txhim kho cov khoom nplaum, txhim kho cov khoom siv khi ntawm cov ntaub ntawv. Qhov no yog qhov tseem ceeb hauv cov ntawv thov zoo li Wallpaper muab tshuaj txhuam, qhov twg adhesion rau ntau qhov chaw yog qhov tseem ceeb.

5. Nto Nta txo qis:

• Qee cov neeg ua haujlwm cellulose muaj lub peev xwm txo qis nro hauv cov tshuab dej. Cov cuab yeej no tau txais txiaj ntsig zoo nyob rau hauv cov ntawv thov xws li xab npum, qhov twg adjected ntub thiab sib kis tau xav tau.

6. Thermal gelation:

• Qee lub cellulose hais tias kev ua kom pom kev ua pov thawj thermal gelation khoom. Qhov no txhais tau tias lawv tuaj yeem tsim cov gels los yog thicken thaum raug kom sov, muab cov kub-nyob ntawm viscosity tswj hwm cov qauv.

7. Kev ruaj khov hauv kev daws teeb meem:

• Cellulose muaj cov neeg hais lus feem ntau feem ntau nthuav tawm qhov ruaj khov kho kom ruaj khov hauv kev daws, tswj lawv cov khoom ntiag tug raws sijhawm. Qhov kev ruaj khov no yog qhov tseem ceeb rau kev ua tau zoo ntev ntawm cov khoom lag luam uas lawv tau siv.

8. Kev sib xyaw nrog lwm cov khoom xyaw:

• Cov cellulose muaj kev hais ua ke tau sib xyaw nrog ntau yam ntawm cov khoom xyaw muaj nyob rau hauv cov qauv, nrog rau cov ntsev, surfactants, thiab lwm cov polymers. Qhov sib xyaw no pub rau ntau yam kev siv hauv kev lag luam ntau yam.

9. Biodegradity:

• Cov cellulose muaj kev hais ua ke tau muab los ntawm cov khoom siv txuas tau yooj yim dua thiab raug suav hais tias biodegradable. Qhov kev ib puag ncig no yog qhov tseem ceeb hauv cov ntawv thov uas biodegradity yog qhov tseem ceeb.

10. Tsis muaj tshuaj lom thiab muaj kev nyab xeeb:

11. Pho stability:

12. Pseudoplastic:

13. Kev ntsuas ntsev:

Nws yog ib qho tseem ceeb kom nco ntsoov tias cov khoom muaj cai ntawm cellulos tuaj yeem sib txawv nyob ntawm seb cov xov tooj ntawm ether thiab nws cov qib siab hloov chaw. Cov chaw tsim khoom muaj cov ntaub ntawv ntxaws ntxaws qhia meej rau txhua cov cellulose khoom siv ntau yam variant rau lawv cov ntawv thov tshwj xeeb.
