Sodium Carboxymethyl cellulose (CMC)ndi chochokera ku mapadi ndi zinthu zachilengedwe polima zinthu zabwino kwambiri monga kusungunuka kwamadzi, mamasukidwe akayendedwe ndi makulidwe. Chifukwa cha biocompatibility yake yabwino, kusakhala ndi kawopsedwe komanso kuwonongeka, CMC imagwiritsidwa ntchito kwambiri muzakudya, mankhwala, mankhwala atsiku ndi tsiku, kupanga mapepala, nsalu, kuchotsa mafuta ndi mafakitale ena. Monga chinthu chofunikira chogwirira ntchito, mulingo wamtundu wa CMC umakhala ndi gawo lofunikira pamagawo osiyanasiyana.
1. Zinthu zoyambira za CMC
Kapangidwe ka mankhwala a AnxinCel®CMC ndikuyambitsa magulu a carboxymethyl (-CH2COOH) kukhala mamolekyu a cellulose, kuti azikhala ndi kusungunuka kwamadzi bwino. Makhalidwe ake akuluakulu ndi awa:
Kusungunuka kwamadzi: CMC imatha kupanga njira yowonekera bwino ya viscous m'madzi ndipo imagwiritsidwa ntchito ngati thickener kapena stabilizer muzinthu zosiyanasiyana zamadzimadzi.
makulidwe: CMC ali mkulu mamasukidwe akayendedwe ndi bwino kuonjezera kugwirizana kwa madzi ndi kuchepetsa fluidity wa madzi.
Kukhazikika: CMC imawonetsa kukhazikika kwamankhwala pama pH osiyanasiyana ndi kutentha.
Biodegradability: CMC ndi yochokera ku cellulose yachilengedwe yokhala ndi kuwonongeka kwachilengedwe komanso magwiridwe antchito abwino kwambiri a chilengedwe.
2. Miyezo yabwino ya CMC
Miyezo yamtundu wa CMC imasiyana malinga ndi magawo osiyanasiyana ogwiritsira ntchito komanso zofunikira. Zotsatirazi ndi zina mwazofunikira zamtundu wapamwamba:
Maonekedwe: CMC iyenera kukhala yoyera kapena yoyera amorphous ufa kapena granules. Pasakhale zonyansa zowoneka ndi zinthu zakunja.
Chinyezi: Chinyezi cha CMC nthawi zambiri sichidutsa 10%. Chinyezi chochulukirapo chidzakhudza kukhazikika kwa kusungirako kwa CMC ndi magwiridwe ake pamapulogalamu.
Kukhuthala: Viscosity ndi chimodzi mwazofunikira za CMC. Nthawi zambiri zimatsimikiziridwa poyesa kukhuthala kwa njira yake yamadzimadzi ndi viscometer. Kuchuluka kwa mamasukidwe akayendedwe, kumapangitsanso kukhuthala kwa CMC. Kuyika kosiyana kwa mayankho a CMC kumakhala ndi zofunikira zosiyana za viscosity, nthawi zambiri pakati pa 100-1000 mPa·s.
Degree of Substitution (DS value): Degree of Substitution (DS) ndi imodzi mwamakhalidwe ofunikira a CMC. Imayimira kuchuluka kwa zolowa m'malo mwa carboxymethyl mugawo lililonse la glucose. Nthawi zambiri, mtengo wa DS umayenera kukhala pakati pa 0.6-1.2. Kutsika kwambiri kwa DS kudzakhudza kusungunuka kwa madzi ndi kukhuthala kwa CMC.
Acidity kapena pH mtengo: Mtengo wa pH wa yankho la CMC nthawi zambiri umayenera kukhala pakati pa 6-8. Kutsika kwambiri kapena kutsika kwa pH kumatha kukhudza kukhazikika ndi kugwiritsa ntchito kwa CMC.
Phulusa: Zomwe zili mu Phulusa ndizomwe zili mu CMC, zomwe nthawi zambiri zimafunikira kuti zisapitirire 5%. Phulusa lalitali kwambiri lingakhudze kusungunuka kwa CMC ndi mtundu wa ntchito yomaliza.
Kusungunuka: CMC iyenera kusungunuka kwathunthu m'madzi kutentha kuti apange njira yowonekera, yoyimitsidwa. CMC yokhala ndi kusungunuka koyipa imatha kukhala ndi zonyansa zosasungunuka kapena mapadi otsika.
Chitsulo cholemera: Zomwe zili muzitsulo zolemera mu AnxinCel®CMC ziyenera kutsata miyezo ya dziko kapena makampani. Nthawi zambiri pamafunika kuti zonse zomwe zili muzitsulo zolemera zisapitirire 0.002%.
Zizindikiro za Microbiological: CMC iyenera kukwaniritsa miyezo yocheperako. Malinga ndi ntchito, chakudya kalasi CMC, mankhwala kalasi CMC, etc. amafuna okhwima kulamulira zili tizilombo zoipa monga mabakiteriya, nkhungu, ndi E. coli.
3. Miyezo yogwiritsira ntchito CMC
Magawo osiyanasiyana ali ndi zofunikira zosiyanasiyana za CMC, chifukwa chake milingo yeniyeni yogwiritsira ntchito iyenera kupangidwa. Miyezo yodziwika bwino yogwiritsira ntchito ndi:
Makampani Food: Food kalasi CMC ntchito thickening, kukhazikika, emulsification, etc., ndipo chofunika kukwaniritsa mfundo chitetezo chakudya, monga sanali poizoni, zoipa, sanali allergenic, ndipo ali ndi madzi solubility wabwino ndi mamasukidwe akayendedwe. CMC itha kugwiritsidwanso ntchito kuchepetsa mafuta ndikuwongolera kukoma ndi kapangidwe ka chakudya.
Makampani opanga mankhwala: Monga wothandizira mankhwala wamba, mankhwala-grade CMC amafuna kulamulira mosamalitsa zonyansa, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda, ndi zina.
Mankhwala atsiku ndi tsiku: Mu zodzoladzola, zotsukira ndi mankhwala ena atsiku ndi tsiku, CMC imagwiritsidwa ntchito ngati thickener, stabilizer, suspending agent, etc., ndipo imayenera kukhala ndi madzi abwino kusungunuka, kukhuthala ndi kukhazikika.
Papermaking makampani: CMC ntchito monga zomatira, ❖ kuyanika wothandizila, etc. mu ndondomeko papermaking, amafuna kukhuthala mkulu, bata ndi mlingo wina wa mphamvu kulamulira chinyezi.
Kugwiritsa ntchito malo opangira mafuta: CMC imagwiritsidwa ntchito ngati chowonjezera chamadzimadzi mumadzi obowola mafuta kuti muwonjezere kukhuthala komanso kupititsa patsogolo madzi. Ntchito zotere zimakhala ndi zofunika kwambiri pakusungunuka komanso kukulitsa kukhuthala kwa CMC.
Ndi chitukuko chosalekeza cha sayansi ndi ukadaulo,CMC, monga zinthu zachilengedwe za polima, zidzapitiriza kukulitsa malo ake ogwiritsira ntchito. Popanga miyezo yapamwamba ya zida za CMC, kuphatikiza pakuganizira zakuthupi ndi zamankhwala, ndikofunikiranso kuganizira mozama zomwe zimafunikira kuti zitsimikizire kuti zitha kukwaniritsa zofunikira zamagawo osiyanasiyana amakampani. Kupanga mfundo zatsatanetsatane komanso zomveka bwino ndi njira yofunikira yowonetsetsa kuti zinthu za AnxinCel®CMC zikuyenda bwino komanso zimagwiritsidwa ntchito, komanso ndiye chinsinsi chothandizira kupikisana pamsika wazinthu za CMC.
