Cov nyhuv ntawm Sodium Carboxymethyl Cellulose nyob rau hauv ntub kawg ntawm daim ntawv zoo

Sodium Carboxymethyl Cellulose (CMC) feem ntau yog siv rau hauv cov txheej txheem papermaking, tshwj xeeb tshaj yog nyob rau hauv ntub kawg, uas nws plays ob peb lub luag hauj lwm tseem ceeb uas yuav cuam tshuam rau daim ntawv zoo. Nov yog li cas CMC cuam tshuam ntau yam ntawm kev tsim cov ntawv:

1. Kev Txhim Kho thiab Kev Txhim Kho Dej Dej:
   • CMC ua raws li kev tuav pov hwm kev pab cuam thiab cov kua dej hauv qhov ntub dej kawg ntawm cov txheej txheem ntawv. Nws txhim kho qhov khaws cia ntawm cov khoom zoo, cov khoom ua kom zoo, thiab cov khoom ntxiv hauv cov pulp slurry, ua rau kev tsim kom zoo dua qub thiab sib xws ntawm daim ntawv. Tsis tas li ntawd, CMC txhim kho cov kua dej los ntawm kev nce tus nqi ntawm cov dej tshem tawm ntawm cov ntaub so ntswg, uas ua rau kom dewatering sai dua thiab txhim kho tshuab efficiency.
2. Formation thiab Uniformity:
   • Los ntawm kev txhim kho kev tuav thiab tso dej, CMC pab txhim kho kev tsim thiab sib xws ntawm daim ntawv. Nws txo qhov kev hloov pauv hauv qhov hnyav, thickness, thiab nto smoothness, ua rau cov khoom zoo sib xws thiab ntau dua. CMC kuj pab txo qhov tsis xws luag xws li pob, qhov, thiab streaks hauv daim ntawv tiav.
3. Txhim kho lub zog:
   • CMC txhawb nqa cov khoom muaj zog ntawm daim ntawv los ntawm kev txhim kho fiber ntau sib txuas thiab kev sib txuas ntawm fiber ntau. Nws ua raws li fiber ntau daim ntawv cog lus, ua kom lub zog tensile, tsim kua muag lub zog, thiab tawg lub zog ntawm daim ntawv. Qhov no ua rau cov khoom lag luam muaj zog thiab ruaj khov dua nrog kev txhim kho kev tiv thaiv tearing, punctureing, thiab folding.
4. Tswj Kev Tsim thiab Sizing:
   • CMC tuaj yeem siv los tswj kev tsim thiab qhov loj ntawm daim ntawv, tshwj xeeb hauv cov ntawv tshwj xeeb. Nws pab tswj kev faib cov fibers thiab fillers nyob rau hauv daim ntawv, nrog rau kev nkag mus thiab tuav cov sizing agents xws li starch los yog rosin. Qhov no ua kom pom kev zoo tshaj plaws luam tawm, tus cwj mem nqus, thiab cov khoom nto hauv daim ntawv tiav.
5. Nto Properties thiab Coatability:
   • CMC pab txhawb rau saum npoo ntawm daim ntawv, cuam tshuam rau yam xws li smoothness, porosity, thiab luam ntawv zoo. Nws txhim kho qhov sib xws ntawm qhov chaw thiab smoothness ntawm daim ntawv, txhim kho nws coatability thiab printability. CMC tseem tuaj yeem ua raws li kev sib khi hauv cov txheej txheem txheej txheej, pab ua kom cov xim thiab cov khoom ntxiv rau ntawm daim ntawv.
6. Control ntawm Stickies thiab Pitch:
   • CMC tuaj yeem pab tswj cov nplaum nplaum (cov nplaum nplaum) thiab pitch (cov tshuaj resinous) hauv cov txheej txheem papermaking. Nws muaj cov nyhuv dispersing ntawm cov nplaum thiab pitch particles, tiv thaiv lawv cov agglomeration thiab deposition rau ntawm daim ntawv tshuab chaw. Qhov no txo ​​cov sij hawm poob, cov nqi tu, thiab cov teeb meem zoo uas cuam tshuam nrog cov nplaum nplaum thiab cov pa paug.

Sodium Carboxymethyl Cellulose (CMC) plays lub luag haujlwm tseem ceeb hauv kev ntub dej kawg ntawm cov txheej txheem papermaking, pab txhawb kev txhim kho kev tuav pov hwm, kev tso dej, tsim, lub zog, cov khoom nto, thiab kev tswj cov kab mob. Nws cov khoom siv ntau yam ua rau nws muaj txiaj ntsig zoo ntxiv rau kev txhim kho cov ntawv zoo thiab kev ua haujlwm hauv ntau qib ntawv thiab kev siv.
