Sodium carboxymethyl cellulose (CMC) pom ntau yam kev siv hauv kev lag luam ntawv vim nws cov khoom tshwj xeeb ua cov polymer yaj hauv dej. Nov yog qee qhov kev siv CMC hauv kev lag luam ntawv:

1. Qhov Loj Ntawm Qhov Chaw:
   • CMC yog siv los ua tus neeg sawv cev rau qhov loj ntawm daim ntawv hauv kev ua ntawv los txhim kho qhov muaj zog ntawm daim ntawv, du thiab yooj yim luam tawm. Nws tsim ib daim nyias nyias rau ntawm daim ntawv, txo qhov porosity ntawm daim ntawv thiab txhim kho qhov tuav ntawm cov kua mem thaum luam ntawv.
2. Qhov Loj Sab Hauv:
   • CMC siv tau rau hauv daim ntawv ua ib yam khoom siv los ntsuas qhov loj ntawm daim ntawv kom daim ntawv tsis txhob nkag mus rau hauv dej thiab tiv thaiv dej kom tsis txhob nkag mus rau hauv. Qhov no pab tiv thaiv kom cov kua mem tsis txhob nthuav dav thiab ua kom cov duab thiab cov ntawv luam tawm zoo dua.
3. Kev Pab Txhawb Nqa Thiab Kev Nqus Dej:
   • CMC ua haujlwm ua ib qho kev pab khaws cia thiab pab kom ntws tawm hauv cov txheej txheem ua ntawv, txhim kho kev khaws cia cov khoom me me thiab cov khoom sau hauv cov ntawv pulp thiab txhim kho kev ntws tawm ntawm lub tshuab ntawv. Qhov no ua rau kev tsim ntawv zoo dua, txo cov ntawv tawg, thiab ua kom lub tshuab ua haujlwm tau zoo dua.
4. Kev Tswj Xyuas Kev Rheology Txheej:
   • Hauv kev tsim cov ntawv coated, CMC yog siv los ua tus hloov pauv rheology hauv cov txheej txheem txheej kom tswj tau qhov viscosity thiab kev ntws. Nws pab tswj kom cov txheej tuab sib npaug, txhim kho kev npog txheej, thiab txhim kho cov yam ntxwv ntawm cov ntawv coated, xws li gloss thiab smoothness.
5. Kev Txhim Kho Zog:
   • CMC tuaj yeem txhim kho lub zog tensile, tear resistance, thiab durability ntawm cov khoom ntawv thaum ntxiv rau hauv daim ntawv pulp. Nws ua haujlwm ua tus binder, txhawb cov fibers thiab txhim kho cov ntawv tsim, uas ua rau cov ntawv zoo dua thiab kev ua tau zoo dua.
6. Kev Tswj Xyuas Cov Khoom Ntawv:
   • Los ntawm kev kho qhov hom thiab qhov concentration ntawm CMC siv rau hauv cov qauv ntawv, cov chaw tsim ntawv tuaj yeem kho cov khoom ntawm daim ntawv kom ua tau raws li cov kev xav tau tshwj xeeb, xws li qhov ci ntsa iab, opacity, stiffness, thiab qhov du ntawm qhov chaw.
7. Kev Txhim Kho Kev Tsim Kho:
   • CMC pab txhim kho kev tsim cov ntawv los ntawm kev txhawb nqa kev sib txuas ntawm cov fiber thiab txo qhov kev tsim cov qhov tsis zoo xws li pinholes, me ntsis, thiab kab. Qhov no ua rau cov ntawv sib xws thiab sib xws dua nrog kev pom zoo dua thiab kev luam tawm zoo dua.
8. Cov Khoom Siv Ntxiv:
   • CMC tuaj yeem ntxiv rau cov ntawv tshwj xeeb thiab cov khoom siv ntawv ua ib qho khoom siv ua haujlwm los muab cov khoom tshwj xeeb, xws li kev tiv thaiv dej noo, cov khoom tiv thaiv static, lossis cov yam ntxwv tso tawm tswj.

sodium carboxymethyl cellulose (CMC) ua lub luag haujlwm tseem ceeb hauv kev lag luam ntawv los ntawm kev pab txhawb rau kev tsim cov ntawv zoo nrog cov khoom zoo, suav nrog lub zog ntawm qhov chaw, kev luam tawm, kev tiv thaiv dej, thiab kev tsim. Nws qhov kev hloov pauv thiab kev ua haujlwm zoo ua rau nws yog ib qho khoom siv ntxiv hauv ntau theem ntawm cov txheej txheem ua ntawv, txij li kev npaj pulp mus rau kev txheej thiab kev ua tiav.
