Carboxymethyl cellulose (CMC) ndi polima wosunthika yemwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana monga chakudya, mankhwala, zodzoladzola, ndi nsalu. Amadziwika kuti amatha kuchita ngati thickening agent, stabilizer, binder, ndi kusunga madzi. Mukasakanizidwa bwino ndi madzi, CMC imapanga yankho la viscous lomwe lili ndi mawonekedwe apadera a rheological.
Kumvetsetsa CMC:
Mapangidwe a Chemical ndi katundu wa CMC.
Ntchito zamafakitale komanso kufunikira m'magawo osiyanasiyana.
Kufunika kosakanikirana koyenera kuti mukwaniritse zomwe mukufuna.
Kusankhidwa kwa Gulu la CMC:
Makalasi osiyanasiyana a CMC omwe amapezeka kutengera kukhuthala, kuchuluka kwa m'malo, komanso chiyero.
Kusankha giredi yoyenera molingana ndi zomwe mukufuna kugwiritsa ntchito komanso mawonekedwe omwe mukufuna yankho.
Malingaliro okhudzana ndi zosakaniza zina mukupanga.
Zida ndi Zida:
Zotengera zoyeretsedwa kuti zisakanizidwe.
Zipangizo zokokera monga makina osonkhezera, zosakaniza, kapena ndodo zogwira pamanja.
Masilinda omaliza maphunziro kapena makapu oyezera kuti muyese molondola CMC ndi madzi.
Njira Zosakaniza:
a. Kusakaniza Kozizira:
Kuonjezera CMC pang'onopang'ono kumadzi ozizira ndikugwedeza kosalekeza kuti muteteze kugwa.
Pang'onopang'ono kuwonjezera mukubwadamuka liwiro kuonetsetsa yunifolomu kubalalitsidwa.
Kulola nthawi yokwanira hydration ndi kuvunda kwa CMC particles.
b. Kusakaniza Kotentha:
Kutenthetsa madzi kutentha koyenera (nthawi zambiri pakati pa 50-80 ° C) musanawonjezere CMC.
Kuwaza pang'onopang'ono CMC m'madzi otentha ndikuyambitsa mosalekeza.
Kusunga kutentha mkati mwazomwe zikulimbikitsidwa kuti zithandizire kutulutsa mwachangu komanso kubalalitsidwa kwa CMC.
c. Kusakaniza Kwambiri:
Kugwiritsa ntchito makina ophatikizira othamanga kwambiri kapena ma homogenizers kuti akwaniritse kubalalitsidwa bwino komanso kuthamanga kwamadzi mwachangu.
Kuwonetsetsa kusintha koyenera kwa zosakaniza zosakaniza kuti mupewe kutentha kwambiri.
Kuyang'anira mamasukidwe akayendedwe ndikusintha magawo osakanikirana ngati pakufunika kuti mukwaniritse mayendedwe omwe mukufuna.
d. Kusakaniza kwa Ultrasonic:
Kugwiritsa akupanga zipangizo kulenga cavitation ndi yaying'ono chipwirikiti mu njira, facilitateng mofulumira kubalalitsidwa kwa CMC particles.
Kuwongolera ma frequency ndi makonzedwe amphamvu kutengera zofunikira za kapangidwe kake.
Kugwiritsa akupanga kusanganikirana monga njira yowonjezera kuti kumapangitsanso kubalalitsidwa ndi kuchepetsa kusanganikirana nthawi.
Kuganizira za Ubwino wa Madzi:
Kugwiritsa ntchito madzi oyeretsedwa kapena osungunula kuti muchepetse zinyalala ndi zowononga zomwe zingakhudze magwiridwe antchito a CMC.
Kuyang'anira kutentha kwa madzi ndi pH kuti muwonetsetse kuti ikugwirizana ndi CMC ndikupewa zoyipa kapena kuwonongeka.
Hydration ndi Dissolution:
Kumvetsetsa ma hydration kinetics a CMC ndikuloleza nthawi yokwanira kuti azitha kutsitsa.
Kuyang'anira mamasukidwe akayendedwe akusintha pakapita nthawi kuti awone momwe kufalikira kukuyendera.
Kusintha magawo osakanikirana kapena kuwonjezera madzi owonjezera ngati pakufunika kuti mukwaniritse kukhuthala komwe mukufuna komanso kusasinthasintha.
Kuwongolera Ubwino ndi Kuyesa:
Kupanga miyeso yama viscosity pogwiritsa ntchito ma viscometers kapena ma rheometers kuti muwone momwe yankho la CMC lilili.
Kuchita tinthu kukula kusanthula kuonetsetsa yunifolomu kubalalitsidwa ndi kupanda agglomerates.
Kuyesa kukhazikika kuti muwunikire moyo wa alumali ndi magwiridwe antchito a yankho la CMC pansi pazikhalidwe zosiyanasiyana zosungira.
Kugwiritsa ntchito CMC-Water Mixtures:
Makampani a Chakudya: Kukhuthala ndi kukhazikika kwa ma sosi, mavalidwe, ndi zinthu zamkaka.
Makampani opanga mankhwala: Kupanga kuyimitsidwa, emulsions, ndi mayankho amaso.
Makampani Odzola Zodzoladzola: Kuphatikizira mu zodzoladzola, mafuta odzola, ndi zinthu zosamalira munthu kuti aziwongolera kukhuthala komanso kukhazikika kwa emulsion.
Makampani Opangira Zovala: Kupititsa patsogolo kukhuthala kwa ma pastes osindikizira ndi ma sizelings.
Kusakaniza CMC m'madzi ndi njira yofunika kwambiri yomwe imafuna kuganizira mozama zinthu zosiyanasiyana monga kusankha kalasi, njira zosakanikirana, mtundu wa madzi, ndi njira zoyendetsera bwino. Potsatira malangizo omwe afotokozedwa mu bukhuli lathunthu, opanga amatha kuonetsetsa kuti CMC imwazikana bwino komanso mogwira mtima, zomwe zimapangitsa kuti pakhale mayankho apamwamba kwambiri omwe amagwira ntchito mosasinthasintha pamagwiritsidwe osiyanasiyana.
