Zotsatira za Sodium Carboxymethyl Cellulose mu Wet End pa Paper Quality

Sodium Carboxymethyl Cellulose (CMC) imagwiritsidwa ntchito kwambiri popanga mapepala, makamaka kumapeto kwamvula, komwe imagwira ntchito zingapo zofunika zomwe zingakhudze kwambiri pepala. Umu ndi momwe CMC imakhudzira magawo osiyanasiyana opanga mapepala:

1. Kusungirako ndi Kupititsa patsogolo Kutayira:
   • CMC imagwira ntchito ngati chothandizira posungira komanso chothandizira kukhetsa madzi kumapeto kwa njira yopangira mapepala. Imawongolera kusungidwa kwa tinthu tating'onoting'ono, zodzaza, ndi zowonjezera mu zamkati slurry, zomwe zimatsogolera ku mapangidwe abwino komanso kufanana kwa pepala. Kuphatikiza apo, CMC imakulitsa ngalande powonjezera kuchuluka komwe madzi amachotsedwa pakuyimitsidwa kwa zamkati, zomwe zimapangitsa kuti madzi azithira mwachangu komanso kuwongolera makina.
2. Kupanga ndi Kufanana:
   • Mwa kukonza kasungidwe ndi ngalande, CMC imathandizira kupititsa patsogolo mapangidwe ndi kufanana kwa pepala. Amachepetsa kusiyana kwa kulemera kwake, makulidwe, ndi kusalala kwa pamwamba, zomwe zimapangitsa kuti pepala likhale losasinthasintha komanso lapamwamba kwambiri. CMC imathandizanso kuchepetsa zolakwika monga mawanga, mabowo, ndi mikwingwirima pamapepala omalizidwa.
3. Kuwonjezera Mphamvu:
   • CMC imathandizira kulimba kwa pepala popititsa patsogolo kulumikizana kwa ulusi komanso kulumikizana kwapakati pa fiber. Imagwira ntchito ngati chowonjezera cha fiber-fiber bond, kukulitsa mphamvu yolimba, kung'ambika, ndi kuphulika kwa pepala. Izi zimapangitsa kuti pepala likhale lamphamvu komanso lolimba kwambiri lomwe silingathe kung'ambika, kubowola, ndi kupindika.
4. Kuwongolera Mapangidwe ndi Kukula:
   • CMC itha kugwiritsidwa ntchito kuwongolera mapangidwe ndi kukula kwa mapepala, makamaka pamakalasi apadera apepala. Zimathandiza kuwongolera kagawidwe ka ulusi ndi zodzaza papepala, komanso kulowa ndi kusungidwa kwa zinthu monga wowuma kapena rosin. Izi zimatsimikizira kusindikizidwa bwino, kuyamwa kwa inki, ndi mawonekedwe apamwamba pamapepala omalizidwa.
5. Katundu Pamwamba ndi Coatability:
   • CMC imathandizira pamapangidwe apamwamba a pepala, kukopa zinthu monga kusalala, porosity, ndi kusindikiza. Zimapangitsa kuti pepala likhale lofanana komanso kuti likhale losalala, ndikupangitsa kuti lizitha kumveka bwino komanso kuti lisindikizidwe. CMC imathanso kukhala ngati chomangira muzopangira zokutira, kuthandiza kumamatira utoto ndi zowonjezera papepala.
6. Kuwongolera kwa Stickies ndi Pitch:
   • CMC ikhoza kuthandizira kuwongolera zomata (zomata zonyansa) ndi phula (zinthu zotulutsa utomoni) popanga mapepala. Ili ndi dispersing kwenikweni pa zomata ndi phula particles, kuteteza agglomeration awo ndi mafunsidwe pa pepala pamwamba makina. Izi zimachepetsa nthawi yocheperako, mtengo wokonza, komanso zovuta zomwe zimagwirizanitsidwa ndi zomata ndi kuipitsidwa kwa phula.

Sodium Carboxymethyl Cellulose (CMC) imagwira ntchito yofunika kwambiri pakunyowa kwa kupanga mapepala, kumathandizira kusungika bwino, ngalande, mapangidwe, mphamvu, mawonekedwe apamwamba, komanso kuwongolera zonyansa. Katundu wake wochita ntchito zambiri umapangitsa kuti ikhale chowonjezera chofunikira chothandizira kukulitsa mtundu wa pepala ndikuchita bwino pamagiredi osiyanasiyana amapepala ndi kugwiritsa ntchito.
