Sodium carboxymethylcellulose (CMC) ndi polima wosunthika komanso wosunthika wokhala ndi ntchito zambiri m'mafakitale osiyanasiyana.Chigawochi chimachokera ku cellulose, polima yachilengedwe yomwe imapezeka m'makoma a cellulose.CMC imapangidwa ndikusintha ma cellulose poyambitsa magulu a carboxymethyl mumsana wa cellulose.Chifukwa cha sodium carboxymethylcellulose imakhala ndi zinthu zapadera zomwe zimapangitsa kuti zikhale zofunikira pamagwiritsidwe ambiri.
Kapangidwe ka Molecular:
Mapangidwe a maselo a sodium carboxymethylcellulose amakhala ndi msana wa cellulose wokhala ndi magulu a carboxymethyl (-CH2-COO-Na) olumikizidwa ndi magulu ena a hydroxyl pamagulu a shuga.Kusintha kumeneku kumapereka kusungunuka ndi zinthu zina zabwino ku polima ya cellulose.
Solubility ndi njira zothetsera:
Chimodzi mwazinthu zazikulu za CMC ndikusungunuka kwake m'madzi.Sodium carboxymethyl cellulose imasungunuka mosavuta m'madzi ndikupanga yankho lowoneka bwino.Kusungunuka kumatha kusinthidwa posintha ma degree of substitution (DS), omwe ndi avareji yamagulu a carboxymethyl pagawo la shuga mu unyolo wa cellulose.
Makhalidwe a Rheological:
Makhalidwe a rheological a mayankho a CMC ndiwowoneka bwino.Kukhuthala kwa mayankho a CMC kumachulukirachulukira ndikuchulukirachulukira kumatengera kuchuluka kwa kulowetsedwa.Izi zimapangitsa CMC kukhala yokhuthala bwino pamagwiritsidwe osiyanasiyana, kuphatikiza chakudya, mankhwala ndi njira zamafakitale.
Ionic katundu:
Kukhalapo kwa ayoni a sodium m'magulu a carboxymethyl kumapatsa CMC mawonekedwe ake a ionic.Chikhalidwe ichi chimalola CMC kuyanjana ndi mitundu ina yoyipiridwa mu njira yothetsera, kupangitsa kuti ikhale yothandiza pamapulogalamu omwe amafunikira kumanga kapena kupanga ma gel.
pH sensitivity:
The solubility ndi katundu wa CMC amakhudzidwa ndi pH.CMC ili ndi kusungunuka kwapamwamba kwambiri ndipo imawonetsa magwiridwe ake abwino pansi pamikhalidwe yamchere pang'ono.Komabe, imakhalabe yokhazikika pamitundu yambiri ya pH, ikupereka kusinthasintha kwamapulogalamu osiyanasiyana.
Kupanga Mafilimu:
Sodium carboxymethylcellulose ili ndi kuthekera kopanga filimu, kupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kupanga mafilimu opyapyala kapena zokutira.Katunduyu angagwiritsidwe ntchito kupanga mafilimu odyedwa, zokutira piritsi, ndi zina.
Khazikitsani:
CMC imakhala yokhazikika pansi pazikhalidwe zosiyanasiyana, kuphatikizapo kutentha ndi kusintha kwa pH.Kukhazikika kumeneku kumathandizira kuti pakhale nthawi yayitali ya alumali komanso kukwanira kwazinthu zambiri.
Emulsion stabilizer:
CMC imagwira ntchito ngati emulsifier yothandiza komanso imathandizira kukhazikika kwa emulsions muzakudya ndi zodzikongoletsera.Imawongolera kukhazikika kwa emulsions yamafuta m'madzi, kumathandizira kupititsa patsogolo moyo wa alumali wazinthu zonse.
Kusunga madzi:
Chifukwa chakutha kuyamwa madzi, CMC imagwiritsidwa ntchito ngati chosungira madzi m'mafakitale osiyanasiyana.Katunduyu ndiwopindulitsa kwambiri pazogwiritsa ntchito monga nsalu, pomwe CMC imathandizira kusunga chinyezi cha nsalu panthawi zosiyanasiyana.
Biodegradability:
Sodium carboxymethylcellulose imatengedwa kuti ndi biodegradable chifukwa imachokera ku cellulose, polima yochitika mwachilengedwe.Mbali imeneyi ndi yochezeka kwambiri ndi chilengedwe ndipo ikugwirizana ndi kufunikira kwa zinthu zokhazikika m'mafakitale ambiri.
ntchito:
makampani azakudya:
CMC imagwiritsidwa ntchito kwambiri ngati thickener, stabilizer ndi texturizer muzakudya.
Imawonjezera mamasukidwe akayendedwe ndi kapangidwe ka sauces, mavalidwe ndi zinthu zamkaka.
mankhwala:
CMC imagwiritsidwa ntchito ngati chomangira pakupanga mapiritsi amankhwala.
Amagwiritsidwa ntchito m'mapangidwe apakhungu kuti apereke mamasukidwe akayendedwe komanso kukulitsa kukhazikika kwa ma gels ndi zonona.
nsalu:
CMC imagwiritsidwa ntchito popanga nsalu ngati chopangira ma size ndi chowonjezera chosindikizira phala.
Imawongolera kumamatira kwa utoto pansalu ndikuwongolera mtundu wosindikiza.
Makampani a Mafuta ndi Gasi:
CMC imagwiritsidwa ntchito pobowola madzi kuwongolera mamasukidwe akayendedwe ndi zolimba zoyimitsidwa.
Imagwira ntchito ngati chochepetsera kutaya madzimadzi ndikuwongolera kukhazikika kwamatope oboola.
Makampani opanga mapepala:
CMC imagwiritsidwa ntchito ngati chopangira mapepala kuti chiwonjezere mphamvu ndi kusindikiza kwa pepala.
Zimagwira ntchito ngati chithandizo chosungira pakupanga mapepala.
Zosamalira munthu:
CMC imapezeka muzinthu zosiyanasiyana zosamalira anthu monga mankhwala otsukira mano ndi shampu ngati thickener ndi stabilizer.
Zimathandizira kuti mawonekedwe onse apangidwe komanso kusasinthika kwazinthu zodzikongoletsera.
Zotsukira ndi zotsukira:
CMC imagwiritsidwa ntchito ngati thickener ndi stabilizer mu zotsukira madzi.
Imawonjezera kukhuthala kwa njira yoyeretsera, kuwongolera magwiridwe antchito ake.
Ceramics ndi Zomangamanga:
CMC imagwiritsidwa ntchito ngati binder ndi rheology modifier muzoumba.
Amagwiritsidwa ntchito pomanga kuti apititse patsogolo kusungirako madzi ndi zomangamanga.
Kawopsedwe ndi chitetezo:
Carboxymethylcellulose nthawi zambiri imadziwika kuti ndi yotetezeka (GRAS) ndi mabungwe owongolera kuti agwiritsidwe ntchito pazakudya ndi mankhwala.Ndiwopanda poizoni ndipo amaloledwa bwino, kupititsa patsogolo kugwiritsidwa ntchito kwake.
Pomaliza:
Sodium carboxymethyl cellulose ndi polima wosiyanasiyana wokhala ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana.Makhalidwe ake apadera, kuphatikizapo kusungunuka kwamadzi, khalidwe la rheological, katundu wa ionic ndi luso lopanga mafilimu, zimapangitsa kuti likhale lofunika kwambiri pa zakudya, mankhwala, nsalu ndi zina zambiri.Pamene mafakitale akupitiriza kufunafuna zipangizo zokhazikika komanso zogwira ntchito zambiri, sodium carboxymethyl cellulose ikuyenera kuwonjezeka kwambiri, ndikulimbitsa udindo wake monga wofunikira kwambiri pa chemistry ya polima ndi ntchito za mafakitale.
