Kev ua haujlwm ntawm Sodium Carboxymethyl cellulose hauv Pigment Txheej

Sodium carboxymethyl cellulose (CMC) yog siv dav hauv cov xim pleev xim rau ntau lub hom phiaj vim nws cov khoom tshwj xeeb. Nov yog qee qhov haujlwm tseem ceeb ntawm sodium carboxymethyl cellulose hauv xim txheej:

1. Binder: CMC ua hauj lwm raws li ib tug binder nyob rau hauv cov xim txheej formulations, pab ua raws li cov pigment hais rau saum npoo ntawm substrate, xws li ntawv los yog cardboard. Nws tsim ib zaj duab xis hloov tau yooj yim thiab cohesive uas khi cov xim pigment ua ke thiab txuas lawv mus rau lub substrate, txhim kho cov txheej txheej adhesion thiab durability.
2. Thickener: CMC ua raws li tus neeg sawv cev thickening nyob rau hauv cov xim txheej formulations, ua rau cov viscosity ntawm txheej txheej. Qhov kev txhim kho viscosity no pab tswj qhov ntws thiab sib kis ntawm cov khoom siv txheej thaum lub sij hawm thov, ua kom muaj kev tiv thaiv ib puag ncig thiab tiv thaiv sagging lossis poob.
3. Stabilizer: CMC stabilizes pigment dispersions hauv txheej txheej los ntawm kev tiv thaiv particle aggregation thiab sedimentation. Nws tsim ib qho kev tiv thaiv colloid nyob ib ncig ntawm cov xim pigment, tiv thaiv lawv los ntawm kev tawm tsam ntawm kev ncua thiab ua kom muaj kev sib faib sib luag thoob plaws hauv cov txheej txheej.
4. Rheology Modifier: CMC ua raws li kev hloov kho rheology nyob rau hauv cov xim txheej txheej, cuam tshuam qhov ntws thiab qib cov yam ntxwv ntawm cov khoom txheej. Nws pab txhim kho cov dej ntws ntawm cov txheej txheem, tso cai rau kom du thiab txawm tias daim ntawv thov mus rau lub substrate. Tsis tas li ntawd, CMC txhim kho cov txheej txheej muaj peev xwm los tawm tsam qhov tsis zoo thiab tsim kom muaj qhov sib xws.
5. Dej Retention Agent: CMC ua tus neeg saib xyuas dej hauv cov txheej txheem xim xim, pab tswj qhov ziab ntawm cov khoom txheej. Nws absorbs thiab tuav rau hauv dej molecules, slowing down the evaporation process and expanding the drying time of the coating. Lub sij hawm ziab qhuav ntev no tso cai rau kom zoo dua qib thiab txo qhov kev pheej hmoo ntawm cov teeb meem xws li tawg lossis tawg.
6. Surface Tension Modifier: CMC hloov kho qhov nro ntawm cov xim txheej txheej, txhim kho ntub dej thiab nthuav tawm cov khoom. Nws txo qhov nro ntawm cov khoom siv txheej txheej, tso cai rau nws kom kis tau tusyees ntau dua ntawm cov substrate thiab ua raws li zoo dua rau saum npoo.
7. pH Stabilizer: CMC pab kom ruaj khov pH ntawm cov xim xim txheej txheej, ua tus neeg sawv cev buffering kom tswj cov qib pH xav tau. Nws pab tiv thaiv kev hloov pauv hauv pH uas tuaj yeem cuam tshuam rau kev ruaj ntseg thiab kev ua haujlwm ntawm cov khoom txheej.

sodium carboxymethyl cellulose plays lub luag haujlwm tseem ceeb hauv cov xim txheej txheej los ntawm kev ua cov ntawv khi, thickener, stabilizer, rheology modifier, dej tuav tus neeg sawv cev, kev hloov kho qhov nro, thiab pH stabilizer. Nws cov khoom siv ntau yam ua rau kev txhim kho txheej adhesion, uniformity, durability, thiab tag nrho cov khoom tiav.
