Cellulose neeg hais txog thiab lawv cov ntawv thov

Cov neeg hais txog cellulose yog ib hom kev kawm ntawm polymers tau muab los ntawm cellulose, lub ntuj polysaccharide pom hauv tsob ntoo phab ntsa. Lawv tau siv dav hauv ntau yam kev lag luam vim lawv cov khoom muaj txiaj ntsig, uas suav nrog cov dej solubility, thickening muaj peev xwm, zaj duab xis-ua yeeb yam muaj peev xwm, thiab kev ua yeeb yaj kiab. Nov yog qee hom ntawm cov kev hais ua ke ntawm cellulose thiab lawv cov ntawv thov:

1. Methyl Cellulose (MC):
   • Cov Ntawv Thov:
     • Kev tsim kho: siv raws li cov neeg sawv cev ntawm cov dej thiab cov dej uas tau tuav tseg hauv Cement-raws li Caas-raws cov nplaum, thiab grouts los txhim kho kev ua haujlwm thiab adhesion.
     • Khoom noj: ua raws li lub thickening thiab ruaj khov rau cov khoom noj khoom noj xws li cov kua zaub, kua zaub, thiab khoom qab zib.
     • Kws Tshuaj Kho Mob: Siv los ua phau ntawv cog lus, thiab ua yeeb yaj kiab-ua yeeb yaj kiab ntawm cov ntsiav tshuaj ntawm cov ntsiav tshuaj thiab cov tshuaj pleev cov kua paug.
2. Hydroxyethyl cellulose (HEC):
   • Cov Ntawv Thov:
     • Kev saib xyuas tus kheej: feem ntau yog siv nyob rau hauv cov tshuaj zawv plaub hau, cleations, thiab cream li lub thickener, ncua cai tus neeg sawv cev.
     • Xim thiab pleev xim: ua haujlwm raws li cov tuab tuab, thiab cov xim sib zog, thiab cov nplaum, thiab cov nplaum, thiab cov nplaum kom txhim kho viscosity thiab sag tsis kam.
     • Kws Tshuaj Kho Mob: Siv ua phau ntawv, stabilizer, thiab viscosity ua kom zoo dua qub, tshuaj pleev xim, thiab cov kua pleev.
3. HydroxyPropyyl methyl cellulose (HPMC):
   • Cov Ntawv Thov:
     • Kev tsim kho: dav siv los ua cov neeg sawv cev dej, cov tuab dua, thiab rheology kho tshuab xws li Mortars, thiab kev ntsuas tus kheej.
     • Kev saib xyuas tus kheej: ua haujlwm hauv cov khoom tu plaub hau, tshuaj pleev ib daim duab, thiab kev tu tawv nqaij ua cov tuab tawv, ua yeeb yaj kiab, thiab emulsifier.
     • Khoom noj: siv ua cov khoom noj tawv thiab ua kom cov khoom noj kom zoo li cov khoom noj xws li misry, bakery, thiab nqaij noj.
4. Carboxymethyl cellulose (CMC):
   • Cov Ntawv Thov:
     • Khoom noj: ua raws li cov tuab yaj ntaub, thiab emulsifier hauv cov khoom noj khoom noj khoom haus, zaub xam lav los txhim kho kev ntxhib los thiab xwm yeem.
     • Kws Tshuaj: Siv los ua phau ntawv, ua txhaum, thiab ncua kev sawv cev hauv cov ntsiav tshuaj hauv cov ntsiav tshuaj hauv cov tshuaj, thiab kua tshuaj kom zoo nkauj.
     • Roj thiab roj: ua haujlwm rau hauv cov kua dej drilling ua ib qho viscosifier, kua dej poob, thiab sharale stabilizer kom txhim kho kev txav thiab muaj kev ruaj khov.
5. Ethyl Hydroxyethyl cellulose (EHEC):
   • Cov Ntawv Thov:
     • Xim thiab pleev xim: ua haujlwm raws li cov tuab, binder, thiab rheology kho hauv cov dej-thiab cov ntawv luam tawm kom tswj viscosity thiab txhim kho cov khoom thov.
     • Kev saib xyuas tus kheej: Siv rau hauv cov khoom siv plaub hau, lub hnub ci, thiab kev tu tawv nqaij, thiab cov neeg sawv cev raug tshem tawm, thiab zaj duab xis-yav dhau los.
     • Kws Tshuaj Kho Mob: Ua haujlwm raws li tus neeg sawv cev tso tawm, binder, thiab viscosity ua kom cov ntaub ntawv tsis zoo, cov ntsiab lus, thiab cov ntsiav tshuaj kom raug tso tawm.

Cov no tsuas yog qee qhov piv txwv ntawm cov kws ua haujlwm ntawm cellulose thiab lawv cov kev thov ntau yam thoob plaws kev lag luam. Cov lus uas muaj ntau yam thiab kev ua tau zoo ntawm cellulose muaj cov neeg muaj cai tseem ceeb ua rau lawv cov khoom ntxiv rau ntau yam khoom lag luam, ua rau txhim kho kev ua haujlwm, ruaj khov, thiab cov khoom tsis zoo.
