Sodium carboxymethyl cellulose (cmc) pom ntau yam kev siv hauv kev lag luam ntawv vim nws cov khoom lag luam zoo li cov dej-soluble polymer. Nov yog qee qhov kev siv ntawm CMC hauv kev lag luam ntawv:

1. Nto sizing:
   • CMC yog siv los ua tus neeg sawv cev ntawm cov neeg sawv cev saum npoo av hauv papermaking kom txhim kho lub sab lub zog, du, thiab tshuab luam ntawv. Nws tsim cov yeeb yaj kiab nyias nyias nyob rau saum npoo ntawm daim ntawv, txo cov porosity thiab kev txhim kho number cases thaum lub sijhawm luam ntawv.
2. Sab hauv sizing:
   • CMC tuaj yeem ntxiv rau daim ntawv pulp raws li tus neeg sawv cev sab hauv los txhim kho daim ntawv tiv thaiv ua kua thiab nce nws cov tshuaj tua dej. Qhov no pab tiv thaiv kab mob kis thiab txhim kho cov qauv luam tawm zoo thiab cov ntawv nyeem.
3. Kev muag khoom thiab tso dej rau kev pab:
   • CMC ua hauj lwm pab ua cov kev pab thiab cov kab mob tawm hauv cov txheej txheem kom zoo, txhim kho cov khoom kom zoo thiab muab tso rau hauv cov ntaub ntawv tso kua mis thiab ua kom huv cov kua dej ua haujlwm ntawm cov tshuab. Qhov no ua rau cov ntawv tsim kev txhim kho, cov ntawv txiav tawm, thiab kev tsim khoom ntau ntxiv.
4. Tswj ntawm txheej txheej rheology:
   • Hauv coated ntawv ntau lawm, cmc yog siv raws li kev ntseeg rheology hauv txheej txheej txheej txheem viscosity thiab ntws tus cwj pwm. Nws pab tswj cov txheej txheej sib dhos thickness, txhim kho cov kev pab them rau txheej txheej, thiab txhim kho cov khoom saum npoo av, xws li gloss thiab smorge.
5. Lub zog ua tau:
   • CMC tuaj yeem txhim kho lub zog tensile, kua muag kuj, thiab cov khoom siv ruaj khov thaum ntxiv rau daim ntawv pulp. Nws ua raws li cov phau ntawv, ntxiv dag zog rau cov fibers thiab txhim kho daim ntawv tsim, uas ua rau kom tau zoo dua cov ntawv zoo thiab ua haujlwm.
6. Tswj cov ntawv khoom:
   • Los kho cov hom thiab kev tsim kho ntawm cmc siv, cov ntawv tsim khoom lag luam tuaj yeem ua kom tau txiav txim siab, xws li ci ntsa iab, opacity, thiab nto smoothness.
7. Kev txhim kho kev txhim kho:
   • CMC pab txhim kho cov ntawv tsim los ntawm kev txhim kho fiber ntau tsev thiab txo qhov kev tsim tawm xws li pinholes, me ntsis, thiab streaks. Qhov no ua rau muaj kev sib txawv ntau dua thiab cov ntawv sau ua ke nrog cov ntawv pom kev pom zoo thiab cov ntawv luam tawm.
8. Ua hauj lwm ntxiv:
   • CMC tuaj yeem ntxiv rau cov ntaub ntawv tshwj xeeb thiab cov khoom siv cov khoom siv tshwj xeeb rau kev ua haujlwm tshwj xeeb, kev tiv thaiv cov khoom zoo li qub, lossis tswj cov yam ntxwv tso tawm.

Sodium carboxymethyl cellulose (cmc) ua cov ntawv tseem ceeb hauv kev lag luam cov khoom lag luam uas xav tau, suav nrog lub zog, luam tawm, thiab kev tsim. Nws cov versatility thiab cov txiaj ntsig ua rau nws muaj txiaj ntsig ntxiv rau ntau theem ntawm cov txheej txheem papermakakaking, los ntawm pulp npaj los txheej thiab xov.
