Ntawm Daim Ntawv Thov Sodium carboxymethyl cellulose hauv Nto Sizing

Sodium carboxymethyl cellulose (CMC) feem ntau yog siv nyob rau hauv daim ntawv kev lag luam rau saum npoo daim ntaub ntawv. Surface sizing yog txheej txheem hauv papermaking qhov twg ib txheej nyias ntawm sizing tus neeg sawv cev yog siv rau saum npoo ntawm daim ntawv los yog ntawv ntawv los txhim kho nws cov khoom nto thiab luam tawm. Nov yog qee qhov kev siv tseem ceeb ntawm sodium carboxymethyl cellulose hauv qhov loj me:

1. Txhim kho Surface Strength:
   • CMC txhim kho lub zog saum npoo ntawm daim ntawv los ntawm kev tsim cov yeeb yaj kiab nyias lossis txheej txheej ntawm daim ntawv. Cov yeeb yaj kiab no txhim kho daim ntawv tiv thaiv kev puas tsuaj, tawg, thiab tawg thaum tuav thiab luam ntawv, ua rau lub ntsej muag du thiab ruaj khov dua.
2. Nto Smoothness:
   • CMC pab txhim kho qhov smoothness thiab uniformity ntawm daim ntawv los ntawm sau nyob rau hauv nto irregularities thiab pores. Qhov no ua rau muaj kev ntxhib los mos ntau dua, uas txhim kho cov ntawv luam tawm thiab pom ntawm daim ntawv.
3. Ink Receptivity:
   • CMC-kho daim ntawv nthuav tawm txhim kho tus cwj mem txais tau thiab cov khoom ntim cov cwj mem. Cov txheej txheej saum npoo tsim los ntawm CMC txhawb nqa tus cwj pwm tsis zoo thiab tiv thaiv tus number case los ntawm kev sib kis lossis feathering, ua rau cov duab zoo nkauj dua thiab muaj zog dua.
4. Surface Sizing Uniformity:
   • CMC xyuas kom meej daim ntawv thov ntawm qhov loj me ntawm daim ntawv, tiv thaiv cov txheej tsis sib xws thiab streaking. Qhov no yuav pab tswj tau qhov sib xws ntawm cov khoom siv thiab luam ntawv zoo thoob plaws hauv daim ntawv yob lossis cov khoom siv.
5. Kev tswj ntawm Deg Porosity:
   • CMC tswj cov porosity saum npoo ntawm daim ntawv los ntawm kev txo nws cov dej nqus dej thiab ua rau nws qhov nro. Qhov no ua rau txo tus number case nkag mus thiab txhim kho xim siv hauv cov duab luam tawm, nrog rau kev txhim kho dej tsis kam.
6. Enhanced Print Quality:
   • Cov ntawv me me uas tau kho nrog CMC nthuav tawm cov ntawv luam tawm zoo dua, suav nrog cov ntawv nyeem zoo dua, cov ntsiab lus zoo dua, thiab cov xim nplua nuj. CMC pab txhawb rau kev tsim cov ntawv luam tawm du thiab zoo ib yam, ua kom muaj kev sib cuam tshuam ntawm tus number case thiab ntawv.
7. Txhim kho Runnability:
   • Daim ntawv kho nrog CMC nyob rau hauv cov txheej txheem sizing saum npoo qhia tau tias kev khiav hauj lwm zoo ntawm cov ntawv luam tawm thiab cov khoom siv hloov pauv. Cov cuab yeej ua kom zoo dua qub txo cov ntawv plua plav, linting, thiab lub vev xaib so, ua rau cov txheej txheem ntau lawm smoother.
8. Txo plua plav thiab xaiv:
   • CMC pab txo cov plua plav thiab xaiv cov teeb meem cuam tshuam nrog cov ntaub ntawv los ntawm kev txhawb nqa fiber ntau thiab txo qis fiber ntau abrasion. Qhov no ua rau cov chaw luam ntawv huv huv thiab txhim kho kev tswj hwm zoo hauv kev luam ntawv thiab hloov pauv cov haujlwm.

sodium carboxymethyl cellulose plays lub luag haujlwm tseem ceeb hauv daim ntawv thov kev loj hlob hauv daim ntawv kev lag luam los ntawm kev txhim kho lub zog saum npoo, smoothness, ink receptivity, sizing uniformity, print quality, runnability, thiab tiv thaiv plua plav thiab xaiv. Kev siv nws ua rau kev tsim cov ntawv zoo nkauj nrog kev pom kev luam ntawv thiab kev txaus siab rau cov neeg siv khoom.
