Kev tsom xam ntawm cov hom ntawm cov kws pab cuam ntawm cellulose siv nyob rau hauv looj cov xim tsev

Cov cellulose muaj kev hais ua ke nyob rau hauv looj cov xim tsev kom hloov ntau cov khoom thiab txhim kho kev ua haujlwm. Ntawm no yog kev tsom xam ntawm cov hom ntawm cov cellulose muaj kev muaj cai ua haujlwm nyob rau hauv looj cov xim duab:

1. Hydroxyethyl cellulose (HEC):
   • Thickening: HEC feem ntau siv los ua cov tuab tuab nyob rau hauv cov xim looj kom muaj ntau cov viscosity thiab txhim kho cov khoom ntawm cov xim ntawm cov xim.
   • Dej khaws cia: HEC pab kom khaws dej hauv cov xim tsim, kom ua kom muaj kev ntub dej kom zoo thiab cais cov pigments thiab ntxiv.
   • Zaj duab xis tsim: hec pab txhawb rau kev tsim cov kev ua si txuas mus ntxiv thiab tsis sib xws thaum ziab, txhim kho cov kav ntev thiab kev pov hwm ntawm cov xim.
2. Methyl Cellulose (MC):
   • Dej Tuav Ruaj: mc ua haujlwm ua dej rov qab los ua kom qhuav ntawm cov xim ziab thiab tso cai rau ncua sijhawm thaum lub sijhawm thov.
   • Stabilization: mc pab tswj cov xim tsim los ntawm kev tiv thaiv xim av thiab txhim kho cov khib nyiab.
   • Txhim kho Adhesion: MC tuaj yeem txhim kho adhesion ntawm cov xim rau ntau yam substrates, kom ntseeg tau zoo dua kev pab them nqi thiab siv taus.
3. HydroxyPropyyl methylcellulose (HPMC):
   • Thickening thiab rheology hloov kho: HPMC muaj cov khoom siv thicking thiab rheology hloov kho, tso cai rau kev tswj hwm cov xim viscosity thiab cov khoom siv.
   • Txhim kho qhov ua haujlwm: HPMC txhim kho cov kev ua haujlwm ntawm cov xim tsev zoo ntawm cov xim looj, pleev xim rau kev nqus lossis ua tiav cov qauv khoom.
   • Stabilization: HPMC stabilizes cov xim tsim, tiv thaiv sagging lossis daws thaum lub sijhawm khaws cia thiab kev thov.
4. Carboxymethyl cellulose (CMC):
   • Dej khaws cia thiab rheology tswj: cmc ua raws li dej rov qab tus neeg saib xyuas thiab rheology kho cov xim tsev, kom ua tiav daim ntawv thov cov khoom siv thiab tiv thaiv xim.
   • Txhim kho ntws thiab theem: CMC pab txhim kho cov dej ntws thiab qib ntawm cov xim, ua rau muaj kev ua kom du thiab ua tiav.
   • Kev ruaj khov: CMC pab txhawb rau kev ruaj ntseg ntawm cov xim tsim, tiv thaiv theem sib cais thiab kav homogeneity.
5. Ethyl Hydroxyethyl cellulose (EHEC):
   • Thickening thiab rheology tswj: EHEC tswj cov khoom siv thickening thiab rheholenology, tso cai rau kev kho kom haum ntawm cov xim viscosity thiab kev thov cov yam ntxwv.
   • Txhim kho Sprest Kuj: EHEC muab kev sib tw tsis kam nyob rau hauv looj cov xim tsev, txo kev sib txig thaum daim ntawv thov tiav.
   • Zaj duab xis tsim: EHEC muaj txiaj ntsig rau kev tsim ntawm cov neeg ruaj khov thiab cov yeeb yaj kiab tsis zoo thaum ziab, txhim kho cov xim pleev xim thiab ua kom ntev.

Ntau hom cellulose cov neeg muaj kev pab cuam hauv looj cov xim tsev los hloov viscosity, txhim kho kev ua kom muaj dej, thiab ua tiav cov khoom thov uas xav tau. Kev xaiv ntawm cellulose tsim nyog ether nyob ntawm yam xws li yam xav tau cov yam ntxwv, substrate hom, thiab txoj kev sau.
