Sodium carboxymethylcellulose (CMC) ndi mankhwala osiyanasiyana omwe amagwiritsidwa ntchito ponseponse m'mafakitale osiyanasiyana, makamaka m'makampani opanga mapepala. Chochokera ku ma carbohydrate awa chimachokera ku cellulose, yomwe ndi polima yachilengedwe yomwe imapezeka m'makoma a cellulose. CMC imapangidwa pochita cellulose ndi sodium hydroxide ndi chloroacetic acid kapena mchere wake wa sodium. Zomwe zimapangidwira zimakhala zosungunuka m'madzi ndipo zimakhala ndi zinthu zapadera zomwe zimapangitsa kuti zikhale zofunikira pazinthu zambiri.
1.Kukonzekera Zamkati:
CMC nthawi zambiri imagwiritsidwa ntchito ngati chigawo chakunyowa kwa njira yopangira mapepala. Imathandiza mu kubalalitsidwa kwa ulusi ndi zina zina m'madzi, kutsogolera mapangidwe homogeneous zamkati slurry.
Kuchuluka kwa madzi ake osungira madzi kumathandiza kusunga kusasinthasintha kwa slurry zamkati, kuonetsetsa kuti mapepala apangidwe mofanana.
2. Kusunga ndi Kutayira:
Imodzi mwazovuta zazikulu pakupanga mapepala ndikukulitsa kusungidwa kwa ulusi ndi zowonjezera pamene mukukhetsa bwino madzi kuchokera muzamkati. CMC imathandizira kuthana ndi vutoli pokonzanso mawonekedwe osungira komanso ngalande.
Monga chithandizo chosungira, CMC imamangiriza ku ulusi ndi chindapusa, kuteteza kutaya kwawo panthawi yopanga pepala.
CMC imathandizira ngalande powonjezera kuchuluka komwe madzi amachotsedwa pazamkati, zomwe zimapangitsa kuti madzi azithira mwachangu komanso kuthamanga kwamakina apamwamba.
3.Kuwonjezera Mphamvu:
CMC imathandizira kulimba kwa pepala, kuphatikiza kulimba kwamphamvu, kukana misozi, ndi mphamvu yophulika. Zimapanga maukonde mkati mwa matrix a pepala, kulimbitsa bwino kapangidwe kake ndikuwonjezera makina ake.
Pakuwongolera mphamvu zamapepala, CMC imalola kupanga magiredi ocheperako pamapepala osataya ntchito, motero kumathandizira kupulumutsa ndalama komanso kugwiritsa ntchito bwino zinthu.
4.Kukula Kwa Pamwamba:
Kukula kwapamwamba ndi gawo lofunika kwambiri popanga mapepala lomwe limaphatikizapo kugwiritsa ntchito kagawo kakang'ono ka saizi pamwamba pa pepalalo kuti lizitha kusindikizidwa, kusalala, komanso kukana madzi.
CMC imagwiritsidwa ntchito ngati choyezera pamwamba chifukwa cha mawonekedwe ake opanga mafilimu komanso kuthekera kowonjezera mphamvu ndi kusalala kwa pamwamba. Zimapanga zokutira zofananira pamapepala, zomwe zimapangitsa kuti inki ikhale yabwino komanso kusindikiza kwabwino.
5.Retention Aid for Fillers and Pigments:
Popanga mapepala, zodzaza ndi inki nthawi zambiri zimawonjezeredwa kuti zisinthe mawonekedwe a pepala monga kusawoneka bwino, kuwala, ndi kusindikiza. Komabe, zowonjezera izi zitha kukhala zosavuta kuti madzi asatayike panthawi yopanga mapepala.
CMC imagwira ntchito ngati chothandizira posungira zodzaza ndi utoto, zomwe zimathandiza kuziyika mkati mwa mapepala a mapepala ndikuchepetsa kutayika kwawo panthawi yakupanga ndi kuyanika.
6.Kulamulira kwa Makhalidwe a Rheological:
Rheology imatanthawuza kayendetsedwe ka kayendedwe ka madzi, kuphatikizapo zamkati slurries, mkati mwa kupanga mapepala. Kuwongolera katundu wa rheological ndikofunikira pakuwongolera magwiridwe antchito komanso mtundu wazinthu.
CMC imakhudza rheology ya zamkati slurries posintha mamasukidwe akayendedwe awo ndi kayendedwe kawo. Itha kugwiritsidwa ntchito kusintha mawonekedwe a rheological a zamkati kuti agwirizane ndi zofunikira pakukonza, monga kuwongolera kuthamanga kwa makina ndi kupanga mapepala.
7. Kuganizira za chilengedwe:
Sodium carboxymethylcellulose nthawi zambiri imadziwika kuti ndi yochezeka ndi chilengedwe, chifukwa imachokera ku magwero a cellulose ongowonjezedwanso ndipo imatha kuwonongeka.
Kugwiritsiridwa ntchito kwake popanga mapepala kungathandize pakupanga mapepala okhazikika pothandizira njira zopangira zogwiritsira ntchito bwino komanso kupititsa patsogolo ntchito zamalonda.
sodium carboxymethylcellulose (CMC) imagwira ntchito zambiri pamakampani opanga mapepala, omwe amagwira ntchito ngati chowonjezera chosunthika chomwe chimawonjezera mbali zosiyanasiyana zakupanga mapepala. Kuchokera pakukonzekera zamkati mpaka kukula kwapamwamba, CMC imathandizira kukonza magwiridwe antchito, mtundu wazinthu, komanso kukhazikika kwa chilengedwe. Kuphatikiza kwake kwapadera kwazinthu kumapangitsa kukhala kofunikira kwa opanga mapepala omwe akufuna kukhathamiritsa magwiridwe antchito ndikukwaniritsa zomwe msika ukufunikira.
