CMC siv hauv kev lag luam ntawv

Carboxymetylcelleculose (CMC) yog siv dav hauv cov ntawv lag luam rau nws cov yam ntxwv zoo li cov dej-soluble polymer. Nws yog muab los ntawm cellulose, lub ntuj polymer pom nyob hauv cov txheej txheem cell phab ntsa, los ntawm kev hloov kho tshuaj lom neeg uas qhia cov pab pawg carboxymethyl. CMC yog siv hauv ntau theem ntawm cov ntawv ntau lawm los txhim kho cov khoom ntawm daim ntawv thiab txhim kho cov kev ua haujlwm ntawm kev tsim cov txheej txheem. Ntawm no yog ob peb tus yuam sij siv CMC hauv kev lag luam ntawv:

1. Nto sizing:
   • CMC yog siv los ua tus neeg sawv cev sab hauv hauv cov ntawv tsim khoom. Nws txhim kho cov khoom saum npoo av, xws li dej tsis kam, tshuab luam ntawv, thiab nyob rau hauv kev ua tau zoo. CMC ua cov yeeb yaj kiab nyias nyias ntawm daim ntawv saum npoo av, koom tes kom zoo dua luam tawm zoo thiab txo qhov kev nkag tsis zoo.
2. Sab hauv sizing:
   • Ntxiv nrog rau saum npoo sizing, CMC tau ua haujlwm raws li tus neeg sawv cev sab hauv. Nws txhim kho cov ntawv tiv thaiv kom nkag mus los ntawm cov kua dej, suav nrog cov dej thiab cov ntawv luam tawm. Qhov no muaj peev xwm ua rau lub zog thiab lub sijhawm ua tiav.
3. Kev muag khoom thiab tso dej rau kev pab:
   • CMC ua raws li kev ua kom ruaj khov thiab tso kua rau thaum lub sijhawm ua haujlwm papermaking. Nws txhim kho cov nyiaj khaws cia ntawm cov fibers thiab lwm yam ntxiv hauv daim ntawv, ua rau tsim zoo dua thiab muaj zog ntxiv. CMC kuj AIDS hauv cov kua dej, txo lub sijhawm nws yuav siv rau cov dej kom raug tshem tawm ntawm daim ntawv pulp.
4. Ntub Dej Ntxiv:
   • CMC tau ntxiv rau cov ntub xaus ntawm cov txheej txheem papermaking raws li kev pab tsis muaj kev pab thiab Flocculant. Nws pab tswj qhov kev ntws thiab faib cov fibers nyob rau hauv daim ntawv slurry, txhim kho cov efficiency ntawm cov ntawv tshuab.
5. Tswj ntawm pulp viscosity:
   • CMC yog siv los tswj lub viscosity ntawm pulp hauv papermaking txheej txheem. Qhov no ua kom cov kev faib tawm ua kom muaj kev faib tawm thiab cov khoom sib ntxiv, txhawb nqa cov ntawv zoo dua thiab txo qis kev pheej hmoo ntawm daim ntawv tsis xws luag.
6. Txhim kho lub zog:
   • Qhov sib ntxiv ntawm CMC pab txhawb rau lub zog muaj zog ntawm daim ntawv, suav nrog lub zog tensile thiab tawg lub zog. Qhov no yog tshwj xeeb yog ib qho tseem ceeb rau kev tsim cov ntaub ntawv nrog kev ua kom tiav durability thiab kev ua tau zoo.
7. Txheej Ntxiv:
   • CMC yog siv los ua kev ntxiv rau hauv cov txheej txheem txheej txheem rau cov ntawv txheej. Nws pab txhawb rau lub rheology thiab kev ruaj ntseg ntawm txheej, txhim kho cov doohness thiab luam tawm zoo ntawm cov ntawv txheej.
8. Tswj Cov Pulp Ph:
   • CMC tuaj yeem ua haujlwm los tswj cov ph txog kev ncua pvc purp. Kev tswj kom muaj PHEM yog qhov tseem ceeb rau kev ua haujlwm zoo rau kev ua tau zoo ntawm ntau cov pa photherging tshuaj.
9. Tsim thiab cov ntawv tsav tsheb:
   • CMC AIDS hauv kev txhim kho qhov tsim thiab kev sib dhos ntawm cov ntawv txheeb. Nws pab tswj tau faib tawm cov fibers thiab lwm yam kev sib dhos, ua rau cov ntawv sau nrog cov khoom ntiag tug.
10. Kev pab kho mob rau cov fillers thiab cov khoom sib ntxiv:
    • CMC ua haujlwm ua cov kev pabcuam tsis tuaj yeem rau cov fillers thiab lwm yam kev sib ntxiv hauv cov ntawv cim. Nws txhim kho cov khoom tuav ntawm cov ntaub ntawv hauv cov ntawv, ua rau kom zoo dua printability thiab zuag qhia tag nrho cov ntawv zoo.
11. Cov txiaj ntsig ib puag ncig:
    • CMC yog lub biodegradable thiab ib puag ncig phooj ywg additive, sib cav nrog kev lag luam tsom rau cov kev coj ua kom ruaj khov.

Hauv cov ntsiab lus, Carboxymethylcelleculose (CMC) ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov ntawv, thiab ua haujlwm zoo ntawm cov khoom lag luam. Nws cov kev siv veratile nyob rau hauv nto sizing, sab hauv sizing, tuav cov nyiaj pab, thiab lwm yam kev pab ua kom muaj txiaj ntsig ntxiv hauv ntau theem ntawm cov ntawv ntau lawm.
