Chiyambi cha Carboxymethyl Cellulose (CMC)
Carboxymethyl cellulose, yomwe nthawi zambiri imafupikitsidwa ngati CMC, ndi yochokera ku cellulose, polima wopezeka mwachilengedwe m'makoma a zomera.Amapezeka kudzera mukusintha kwamankhwala a cellulose, makamaka poyambitsa magulu a carboxymethyl (-CH2-COOH) pamsana wa cellulose.
Kapangidwe ndi Katundu
CMC imasungabe kapangidwe ka cellulose, komwe ndi mzere wofananira wa mamolekyu a shuga olumikizidwa ndi β(1→4) ma glycosidic bond.Komabe, kuyambitsidwa kwa magulu a carboxymethyl kumapereka zinthu zingapo zofunika ku CMC:
Kusungunuka kwamadzi: Mosiyana ndi cellulose yachilengedwe, yomwe sisungunuka m'madzi, CMC imasungunuka kwambiri m'madzi otentha komanso ozizira chifukwa cha hydrophilic yamagulu a carboxymethyl.
Thickening Agent: CMC ndi njira yolimbikitsira, yomwe imapanga mayankho a viscous pamalo otsika.Katunduyu amapangitsa kuti ikhale yamtengo wapatali pamagwiritsidwe osiyanasiyana, kuphatikiza chakudya, mankhwala, ndi zinthu zosamalira anthu.
Kutha Kupanga Mafilimu: CMC imatha kupanga mafilimu ikasungidwa kuchokera ku yankho, kupangitsa kuti ikhale yothandiza pakugwiritsa ntchito pomwe filimu yopyapyala, yosinthika imafunikira, monga zokutira ndi zomatira.
Kukhazikika ndi Kugwirizana: CMC ndi yokhazikika pamitundu yosiyanasiyana ya pH ndi kutentha, ndikupangitsa kuti ikhale yogwirizana ndi zosakaniza zina zosiyanasiyana komanso zoyenera kugwiritsa ntchito mosiyanasiyana.
Mapulogalamu
Zinthu zosunthika za CMC zimapeza ntchito m'mafakitale angapo:
Makampani a Chakudya: CMC imagwiritsidwa ntchito kwambiri monga chowonjezera, chokhazikika, ndi emulsifier muzakudya monga sosi, mavalidwe, ayisikilimu, ndi zinthu zophika buledi.Imawongolera kapangidwe kake, kamvekedwe ka mkamwa, komanso kukhazikika kwa shelufu.
Pharmaceuticals: Pakupanga mankhwala, CMC imagwira ntchito ngati binder, disintegrant, and controlled-release agent m'mapiritsi ndi makapisozi.Kutha kwake kupanga ma gels okhazikika kumapangitsanso kuti ikhale yothandiza pamapangidwe apamutu monga zonona ndi mafuta odzola.
Zopangira Zosamalira Pawekha: CMC ndi chinthu chodziwika bwino pamankhwala osamalira anthu monga mankhwala otsukira mano, ma shampoos, ndi zopaka mafuta, komwe amagwira ntchito ngati thickener, stabilizer, ndi chosungira chinyezi.
Makampani Opanga Mapepala: Pakupanga mapepala, CMC imagwiritsidwa ntchito ngati chinthu choyezera pamwamba kuti chiwonjezere mphamvu zamapepala, kusalala, komanso kulandila kwa inki.Zimagwiranso ntchito ngati chothandizira posungira, kuthandizira kumangirira tinthu tating'onoting'ono ndi ma fillers pamapepala.
Zovala: CMC imagwiritsidwa ntchito posindikiza nsalu ndi njira zopaka utoto ngati chowonjezera komanso chosinthira ma rheology posindikiza phala ndi malo osambira a utoto.
Kubowola Mafuta: Pamakampani obowola mafuta, CMC imawonjezedwa kumadzi obowola kuti azitha kuwongolera kukhuthala, kuchepetsa kutaya kwamadzimadzi, komanso kuthira mafuta obowola.
Kugwiritsiridwa ntchito kofala kwa carboxymethyl cellulose kumatheka chifukwa cha kuphatikiza kwake kwapadera, komwe kumathandizira kugwiritsidwa ntchito kwake m'magawo osiyanasiyana.Kuwonongeka kwake kwachilengedwe komanso kusakhala ndi kawopsedwe kumathandiziranso kukopa kwake ngati njira yokhazikika komanso yosamalira zachilengedwe m'malo mwa ma polima opangira muzinthu zambiri.
carboxymethyl cellulose ndi ether ya cellulose yomwe imagwiritsidwa ntchito mosiyanasiyana chifukwa cha kusungunuka kwake m'madzi, kukhuthala kwake, kukhazikika, komanso kuyanjana ndi zinthu zina.Kufunika kwake kumafalikira m'mafakitale ambiri, ndikupangitsa kuti ikhale yofunika kwambiri pazogulitsa ndi njira zambiri.
