Cellulose ether hauv txheej

Neeg muaj neeg ua haujlwmUa si lub luag haujlwm tseem ceeb hauv kev ua yeeb yam thoob plaws ntau yam lag luam. Lawv muaj nuj nqis rau lawv lub peev xwm los hloov kho cov hluav taws xob rheological, txhim kho cov dej khaws cia, txhim kho zaj duab xis, thiab pab txhawb kev ua yeeb yam. Ntawm no yog qee qhov tseem ceeb ntawm cov neeg ua kom muaj kev ua kom muaj kev nyab xeeb nyob rau hauv cov tsho tiv no:

1. Viscosity thiab rheology tswj:
   • Cov neeg saib xyuas tuab: cellulose cov neeg hais ua tau zoo raws li ua tau zoo siv cov tuab hauv cov txheej txheej. Lawv tau nce viscosity, muab qhov xav tau kev sib thooj rau kev thov.
   • Rheological tswj: lub zog rheological ntawm cov txheej txheem, xws li ntws thiab leveling, tuaj yeem raug tswj hwm los ntawm kev sib txuam nrog kev hais ua cellulge.
2. Dej khaws cia:
   • Kev ua kom cov dej sib luag: HydroxyPropyyl methylcellose (HPMC) thiab lwm yam neeg ua haujlwm hauv cellulose tau paub txog lawv cov khoom siv dej. Hauv cov txheej txheej, qhov no pab tiv thaiv kom txhob muaj kev ua kom qhuav ntawm cov khoom siv, tso cai rau kev ua haujlwm zoo dua thiab txhim kho zaj duab xis tsim.
3. Txhim kho zaj duab xis:
   • Zaj duab xis-ua tus sawv cev: qee cov cellulose muaj kev hais kom muaj kev ua tau zoo li cov yeeb yaj kiab txuas ntxiv (EC) ntawm cov yeeb yaj kiab txuas ntxiv thiab cov yeeb yaj kiab tsis zoo rau ntawm cov chaw seem.
4. Ruaj khov ntawm pigments thiab fillers:
   • Stabililizer: Cov neeg siv cellulose tuaj yeem ua haujlwm ua haujlwm ruaj khov, tiv thaiv kev sib tw thiab agglomeration ntawm cov pigments thiab fillers nyob rau hauv txheej formulations. Qhov no ua kom muaj kev faib khoom homogeneous faib ntawm cov lus thiab txhim kho kom muaj kev ruaj ntseg tag nrho ntawm cov txheej.
5. Adhesion qib:
   • Adhesion shreprover: cov cellulose muaj kev pab hais tau rau kom zoo dua zoo dua ntawm txheej thiab substrate, coj los txhim kho durability thiab kev ua tau zoo.
6. Tswj Tso Tes Tsho:
   • Cov ntawv tso cai tso tawm: Hauv cov ntawv thov tshwj xeeb, cov neeg siv cellulose yuav siv rau hauv cov tsho tiv no rau tswj cov laj thawj. Qhov no tshwj xeeb tshwj xeeb hauv cov txheej txheem tshuaj pleev xim rau qhov uas tau muab tshuaj tso tawm yog xav tau.
7. Mating cov chaw muag khoom:
   • Matting cov nyhuv: nyob rau hauv qee cov txheej txheem, cellulose muaj cov neeg hais ua ke tuaj yeem muab cov txiaj ntsig zoo, txo qhov ci ci thiab tsim lub matte tiav. Qhov no feem ntau yog cov ntoo uas ntxim nyiam, rooj tog zaum, thiab muaj qee yam muaj kev muaj yees.
8. Kev txiav txim siab ib puag ncig:
   • Biodegradity: cellulose lus hais tias feem ntau feem ntau biodegradable, pab txhawb rau kev txhim kho ntawm ib puag ncig tus phooj ywg.
9. Compatibility nrog lwm cov tshuaj ntxiv:
   • Versatility: Cellulose Cov neeg muaj kev hais ua ke muaj ntau cov txheej sib ntxiv, tso cai rau cov kws sau ntxiv los tsim cov qauv nrog cov yam ntxwv tshwj xeeb.
10. Ntau yam ntawm cellulose muaj cov neeg muaj cai:
    • Xaiv cov khoom: cov cellulose cellulose txawv, xws li HPMC, CMC, HEC, thiab muaj ntau yam kev xaiv tsim nyog rau lawv cov ntawv thov txheej txheej.

Kev siv cov cellulose muaj kev muaj zog nyob sib txawv ntawm cov txheej txheem sib txawv, xws li kev tsim kho, pleev xim rau thiab txheej, thiab lwm yam. Cov ntawv sau feem ntau cov kws ntaus ntawv ua tiav kom ua tiav qhov kev xav sib npaug ntawm cov khoom lag luam rau cov khoom siv txheej tshwj xeeb, ua kom zoo dua cov lus qhia los ntawm cellulose neeg muaj kev pab.
