Carboxymethyl cellulose (CMC)ndi anionic cellulose ether yopangidwa ndi kusintha kwa mankhwala a cellulose. Amagwiritsidwa ntchito kwambiri m'zakudya, mankhwala, mankhwala a tsiku ndi tsiku, mafuta a petroleum, kupanga mapepala ndi mafakitale ena chifukwa cha kukhuthala bwino, kupanga mafilimu, kutsekemera, kuyimitsa ndi kunyowa. CMC ili ndi magiredi osiyanasiyana. Malinga ndi chiyero, digiri ya m'malo (DS), mamasukidwe akayendedwe ndi zochitika zomwe zimagwira ntchito, masukulu wamba amatha kugawidwa m'magawo a mafakitale, kalasi yazakudya ndi kalasi yamankhwala.
1. Industrial grade carboxymethyl cellulose
Industrial grade CMC ndi chinthu chofunikira chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale ambiri. Amagwiritsidwa ntchito makamaka m'minda yamafuta, kupanga mapepala, zoumba, nsalu, kusindikiza ndi utoto ndi mafakitale ena, makamaka pochiza matope pakuchotsa mafuta ndi kulimbikitsa ntchito yopanga mapepala.
Viscosity: The mamasukidwe akayendedwe osiyanasiyana mafakitale kalasi CMC ndi lonse, kuyambira otsika mamasukidwe akayendedwe akayendedwe akayendedwe mkulu kuti akwaniritse zosowa zosiyanasiyana ntchito. High mamasukidwe akayendedwe CMC ndi oyenera ntchito ngati binder, pamene otsika mamasukidwe akayendedwe ndi oyenera ntchito monga thickener ndi stabilizer.
Digiri ya m'malo (DS): Mlingo wolowa m'malo mwa CMC wamba wamakampani ndi otsika, pafupifupi 0.5-1.2. Kutsika pang'ono m'malo kumatha kukulitsa liwiro lomwe CMC imasungunuka m'madzi, kulola kuti ipange colloid mwachangu.
Malo ofunsira:
Kuboola mafuta:CMCamagwiritsidwa ntchito ngati thickener ndi kuyimitsa wothandizira pobowola matope kupititsa patsogolo rheology ya matope ndi kuteteza kugwa kwa khoma la chitsime.
Makampani opanga mapepala: CMC ikhoza kugwiritsidwa ntchito ngati chowonjezera chamkati kuti chiwongolere kulimba kwamphamvu komanso kupindika kwa pepala.
Makampani a Ceramic: CMC imagwiritsidwa ntchito ngati chokhuthala cha glazes za ceramic, zomwe zimatha kupititsa patsogolo kumamatira ndi kusalala kwa glaze ndikuwonjezera kupanga filimu.
Ubwino: Industrial grade CMC ili ndi mtengo wotsika ndipo ndiyoyenera kupanga mafakitale akuluakulu.
2. Carboxymethyl cellulose ya chakudya
Chakudya kalasi CMC chimagwiritsidwa ntchito makampani chakudya, makamaka monga thickener, emulsifier, stabilizer, etc. kukonza kukoma, kapangidwe ndi alumali moyo wa chakudya. Gulu ili la CMC lili ndi zofunika kwambiri paukhondo, mfundo zaukhondo ndi chitetezo.
Viscosity: Kukhuthala kwa CMC ya kalasi yazakudya nthawi zambiri kumakhala kotsika mpaka pakati, nthawi zambiri kumayendetsedwa pakati pa 300-3000mPa·s. Kukhuthala kwapadera kudzasankhidwa malinga ndi momwe ntchito ikugwiritsidwira ntchito komanso zosowa zamalonda.
Digiri ya m'malo (DS): Mlingo wolowa m'malo mwa CMC wa kalasi ya chakudya nthawi zambiri umayendetsedwa pakati pa 0.65-0.85, womwe ungapereke kukhuthala kwapakati komanso kusungunuka kwabwino.
Malo ofunsira:
Zamkaka: CMC imagwiritsidwa ntchito muza mkaka monga ayisikilimu ndi yogati kuti iwonjezere kukhuthala komanso kukoma kwa mankhwalawa.
Zakumwa: Mu zakumwa zamadzi ndi tiyi, CMC imatha kukhala ngati choyimitsira choletsa kuti zamkati zisakhazikike.
Zakudyazi: Mu Zakudyazi ndi Zakudyazi za mpunga, CMC imatha kuwonjezera kulimba ndi kukoma kwa Zakudyazi, kuzipangitsa kukhala zotanuka.
Zokometsera: Mu sosi ndi mavalidwe a saladi, CMC imagwira ntchito ngati yokhuthala komanso emulsifier kuti ipewe kulekanitsa kwamadzi ndi mafuta ndikuwonjezera moyo wa alumali.
Ubwino: CMC ya kalasi yazakudya imakwaniritsa miyezo yaukhondo wazakudya, ilibe vuto kwa thupi la munthu, imasungunuka m'madzi ozizira ndipo imatha kupanga ma colloid mwachangu, ndipo imakhala ndi zotsatira zabwino kwambiri zokulitsa ndi kukhazikika.
3. Pharmaceutical-grade carboxymethyl cellulose
Mankhwala-kalasiCMCimafunikira miyezo yapamwamba yachiyero ndi chitetezo ndipo imagwiritsidwa ntchito makamaka popanga mankhwala ndi zida zamankhwala. Gulu ili la CMC liyenera kukwaniritsa miyezo ya pharmacopoeia ndikuwongolera mosamalitsa kuti likhale lopanda poizoni komanso losakwiyitsa.
Viscosity: Mitundu yosiyanasiyana ya ma CMC amtundu wamankhwala amayeretsedwa kwambiri, nthawi zambiri pakati pa 400-1500mPa · s, kuwonetsetsa kukhazikika kwake komanso kukhazikika pazamankhwala ndi zamankhwala.
Degree of substitution (DS): Mlingo wolowa m'malo mwa kalasi yamankhwala nthawi zambiri umakhala pakati pa 0.7-1.2 kuti apereke kusungunuka koyenera ndi kukhazikika.
Malo ofunsira:
Kukonzekera kwa mankhwala: CMC imakhala ngati binder ndi disintegrant pamapiritsi, omwe amatha kuonjezera kuuma ndi kukhazikika kwa mapiritsi, komanso amatha kusungunuka mofulumira m'thupi.
Madontho a m'maso: CMC imagwira ntchito ngati chowonjezera komanso chonyowa kwa mankhwala a ophthalmic, omwe amatha kutsanzira misozi, kuthandizira kudzoza m'maso, ndikuchepetsa zizindikiro zamaso.
Kuvala pabala: CMC ikhoza kupangidwa kukhala filimu yowonekera komanso zobvala ngati gel osamalira mabala, ndi kusunga chinyezi komanso kupuma bwino, kulimbikitsa machiritso a bala.
Ubwino: Gulu lachipatala CMC limakumana ndi miyezo ya pharmacopoeia, ili ndi biocompatibility yayikulu komanso chitetezo, ndipo ndiyoyenera pakamwa, jekeseni ndi njira zina zowongolera.
4. Makalasi apadera a carboxymethyl cellulose
Kuphatikiza pa magiredi atatu omwe ali pamwambawa, CMC imathanso kusinthidwa malinga ndi zosowa zenizeni za magawo osiyanasiyana, monga kalasi yodzikongoletsera ya CMC, kalasi yotsukira mano CMC, ndi zina zotere.
Cosmetic grade CMC: yogwiritsidwa ntchito posamalira khungu, masks amaso, ndi zina zotero, kupanga mafilimu abwino komanso kusunga chinyezi.
Mankhwala otsukira m'mano kalasi CMC: ntchito monga thickener ndi zomatira kupereka otsukira mkamwa bwino phala mawonekedwe ndi fluidity.
Carboxymethyl celluloseali osiyanasiyana ntchito ndi zosiyanasiyana kalasi options. Gulu lililonse lili ndi zinthu zina zakuthupi ndi zamankhwala kuti zikwaniritse zosowa zamafakitale osiyanasiyana.
