Carboxymethyl cellulose CMC-Papermaking kalasi

Kufotokozera Kwachidule:

Carboxymethylation reaction ndi imodzi mwamaukadaulo a etherification.Pambuyo pa carboxymethylation ya cellulose, carboxymethyl cellulose (CMC) imapezeka.Njira yake yamadzimadzi imakhala ndi ntchito za thickening, kupanga mafilimu, kugwirizanitsa, kusunga madzi, chitetezo cha colloidal, emulsification ndi kuyimitsidwa.Amagwiritsidwa ntchito kwambiri m'mafakitale amafuta, chakudya, mankhwala, nsalu ndi kupanga mapepala.Ndi imodzi mwazinthu zofunika kwambiri za cellulose ethers.Ndi ukatswiri wathu wanthawi yayitali pakugulitsa zinthu zama mankhwala, kodi timakupatsirani upangiri waukadaulo pazogulitsa ndi mayankho ogwirizana ndi cholinga chanu.Ndife okondwa kukuthandizani kusankha zida zoyenera kwa inu.Ingodinani kuti mupeze ntchito mumakampani anu: CMC muzakudya, petroleum, kusindikiza ndi utoto, zoumba, zotsukira mano, zoyandama beneficiation, batire, zokutira, putty ufa ndi papermaking.

Mapepala kalasi CMC chitsanzo: NX-1/3/5 , NX-10/30/100, NX-150/300/700
CMC ndi chowonjezera chabwino cha zokutira, chomwe chimatha kuwongolera kuwongolera kwa zokutira, ndipo chimakhala ndi zomatira komanso kupanga mafilimu.Ndizoyenera zokutira zolimba kwambiri komanso zokutira zothamanga kwambiri.
CMC imagwiritsidwa ntchito popanga masanjidwe apamwamba, omwe amatha kusintha bwino kusalala, mphamvu ndi mpweya wa pepala ndikupeza kusindikiza kwabwino.
CMC imagwiritsidwa ntchito kumapeto kwa makina a pepala ngati chowonjezera komanso chosungirako kuti chikhale chofanana komanso champhamvu cha pepala, kukonza kasungidwe ka makinawo, ndikupereka kuchuluka kwake.

CMC-Kugwiritsa Ntchito Mu Paper Viwanda

1, Udindo waukulu wa CMC mu zokutira pigment
- Kuwongolera ndikusintha mawonekedwe a zokutira ndi kubalalitsidwa kwa pigment kuti apititse patsogolo zolimba za zokutira;
- Pangani zokutira kukhala ndi pseudoplasticity ndikuwongolera kuthamanga kwa zokutira;
- Kupititsa patsogolo kusungidwa kwamadzi kwa zokutira ndikuletsa kusuntha kwa zomatira zosungunuka m'madzi;
- Ili ndi katundu wabwino wopanga filimu ndikuwongolera gloss ya zokutira;
- Kupititsa patsogolo kuchuluka kwa zowunikira pakupaka ndikuwongolera kuyera kwa pepala;
- Sinthani magwiridwe antchito a zokutira, sinthani mtundu wa zokutira ndikutalikitsa moyo wautumiki wa scraper.
2. Udindo waukulu wa CMC pakuwonjezera slurry
- Sinthani magwiridwe antchito a zamkati, kulimbikitsa kuwongolera kwa fiber, kufupikitsa nthawi yomenyedwa;
- Sinthani kuthekera kwazamkati, kugawanitsa ulusi wofanana, sinthani makina amapepala "kutengera magwiridwe antchito", kupititsa patsogolo mapangidwe atsamba;
- Sinthani kuchuluka kwa zosungirako zosiyanasiyana, zodzaza ndi ulusi wabwino;
- Wonjezerani mphamvu yomangirira pakati pa ulusi, sinthani mawonekedwe a pepala;
- Kugwiritsidwa ntchito ndi mphamvu youma ndi yonyowa, kumatha kupititsa patsogolo kuuma ndi kunyowa kwa pepala;
- Tetezani rosin, AKD ndi ma saizi ena mu zamkati, onjezerani kukula kwake.
3. Udindo waukulu wa CMC pakukula kwapamwamba
- Ili ndi rheology yabwino komanso kupanga mafilimu;
- Kuchepetsa pores pamapepala ndikuwongolera kukana kwamafuta pamapepala;
- Wonjezerani kuwala ndi gloss ya pepala;
- Wonjezerani kuuma ndi kusalala kwa pepala ndikuwongolera ma curl;
- Kupititsa patsogolo mphamvu ya pamwamba ndi kuvala kukana kwa pepala, kuchepetsa tsitsi ndi kutayika kwa ufa, ndikuwongolera khalidwe losindikiza.
