Sodium carboxymethyl cellulose (CMC) pom ntau daim ntawv thov hauv kev lag luam ntawv vim nws cov khoom tshwj xeeb xws li dej-soluble polymer. Nov yog qee qhov kev siv ntawm CMC hauv kev lag luam ntawv:

1. Surface Size:
   • CMC yog siv los ua tus neeg saib xyuas qhov loj me hauv kev ua cov ntaub ntawv los txhim kho lub zog saum npoo, smoothness, thiab luam ntawv ntawm daim ntawv. Nws tsim ib zaj duab xis nyias ntawm daim ntawv, txo qhov porosity ntawm qhov chaw thiab txhim kho tus cwj mem tuav thaum luam ntawv.
2. Internal Size:
   • CMC tuaj yeem muab ntxiv rau hauv daim ntawv pulp ua tus neeg sawv cev sab hauv los txhim kho daim ntawv tiv thaiv cov kua nkag thiab ua kom nws cov dej tawm. Qhov no yuav pab tiv thaiv kom tsis txhob kis tus lej thiab txhim kho cov duab luam tawm thiab cov ntawv zoo.
3. Retention thiab Drainage Aid:
   • CMC yog ib qho kev pab khaws cia thiab cov kua dej hauv cov txheej txheem papermaking, txhim kho kev tuav cov khoom zoo thiab cov khoom ntim rau hauv cov ntawv sau thiab txhim kho cov dej ntws tawm ntawm lub tshuab ntawv. Qhov no ua rau kev txhim kho cov ntawv tsim, txo cov ntawv so, thiab ua kom lub tshuab ua haujlwm tau zoo.
4. Tswj Txheej Rheology:
   • Hauv kev tsim cov ntawv coated, CMC yog siv los ua tus hloov kho rheology hauv txheej txheej los tswj cov viscosity thiab ntws tus cwj pwm. Nws pab tswj cov txheej txheej tuab, txhim kho txheej txheej, thiab txhim kho cov khoom ntawm cov ntawv coated, xws li gloss thiab smoothness.
5. Txhim kho lub zog:
   • CMC tuaj yeem txhim kho lub zog tensile, tsim kua muag, thiab kav ntev ntawm cov khoom siv ntawv thaum ntxiv rau daim ntawv pulp. Nws ua raws li kev sib khi, ntxiv dag zog rau cov fibers thiab txhim kho cov ntawv tsim, uas ua rau cov ntawv zoo dua qub thiab kev ua haujlwm zoo.
6. Tswj Cov Khoom Siv:
   • Los ntawm kev kho hom thiab concentration ntawm CMC siv nyob rau hauv papermaking formulations, daim ntawv manufacturers tuaj yeem kho cov khoom ntawm daim ntawv kom tau raws li cov kev cai tshwj xeeb, xws li brightness, opacity, nruj, thiab nto smoothness.
7. Kev Txhim Kho Kev Tsim Kho:
   • CMC pab txhim kho kev tsim cov ntawv los ntawm kev txhawb nqa fiber ntau thiab txo qhov tsim ntawm qhov tsis xws luag xws li pinholes, me ntsis, thiab streaks. Qhov no ua rau cov ntaub ntawv zoo sib xws thiab zoo ib yam nrog kev pom kev zoo dua thiab kev luam tawm.
8. Functional Additive:
   • CMC tuaj yeem muab ntxiv rau cov ntaub ntawv tshwj xeeb thiab cov khoom siv los ua cov khoom siv ntxiv rau kev faib cov khoom tshwj xeeb, xws li dej tsis kam, cov khoom tiv thaiv zoo li qub, lossis cov yam ntxwv tso tawm.

sodium carboxymethyl cellulose (CMC) plays lub luag haujlwm tseem ceeb hauv kev lag luam ntawv los ntawm kev ua haujlwm ntawm cov ntaub ntawv zoo nrog cov khoom tsim nyog, suav nrog lub zog saum npoo, luam tawm, dej tsis kam, thiab tsim. Nws versatility thiab kev ua tau zoo ua rau nws muaj txiaj ntsig zoo ntxiv hauv ntau theem ntawm cov txheej txheem papermaking, los ntawm kev npaj pulp mus rau txheej thiab xov.
