Kapangidwe ka mankhwala kwa cellulose ether

Cellulose ndi zochokera kwa cellulose, polysaczacdide wachilengedwe wopezeka m'makoma a cell a mbewu. Kupanga kwa mankhwala kwa cellulose kumadziwika ndi kuyambitsa magulu osiyanasiyana kwa ether kudzera mu mankhwala a hydroxyl (--Oh) amapezeka mu cellulose molekyulu. Mitundu yodziwika bwino ya cellulose yophatikizika ndi:

1. Hydroxypropyl methylcellulose (hpmc):
   • Kapangidwe:
     • HPMC imapangidwa ndi kuloweza ma hydroxyl magulu a cellulose okhala ndi hydroxypropyl (-och2chohch3) ndi methyl (-Och3).
     • Mlingo wa zolowetsa (DS) akuwonetsa kuchuluka kwa mitundu ya hydroxyl mu gawo la glucose mu cellulose unyolo.
2. Carboxymethyl cellulose(Cmc):
   • Kapangidwe:
     • CMC imapangidwa poyambitsa carboxymethyl (-ch2cooh) magulu magulu a hydroxyl a cellulose.
     • Magulu a Carboxymethyl amapatsa madzi kusungunuka ndi anionic ndi ma cellulose unyolo.
3. Hydroxyethyl cellulose (hec):
   • Kapangidwe:
     • Hec imachokera ku kuloweza ma gydroxyl magulu a cellulose ndi hydroxyethyl (-Och2ch2oh).
     • Imawonetsa kukonzanso madzi osungunuka ndi makulidwe.
4. Methyl cellulose (MC):
   • Kapangidwe:
     • MC imapangidwa poyambitsa methyl (-Och3) magulu magulu a hydroxyl a cellulose.
     • Nthawi zambiri imagwiritsidwa ntchito posungira madzi ndi mawonekedwe ake.
5. Ethyl cellulose (EC):
   • Kapangidwe:
     • EC yapangidwa ndi kuloweza ma hydroxyl magulu a cellulose ndi ethyl (--coc2h) magulu.
     • Amadziwika chifukwa cha kusungunuka m'madzi ndipo nthawi zambiri amagwiritsidwa ntchito popanga zokutira ndi mafilimu.
6. Hydroxypyl cellulose (hpc):
   • Kapangidwe:
     • HPC imachokera pakuyambitsa hydroxypropyl (-och2chohch3) magulu kupita ku magulu a hydroxyl a cellulose.
     • Amagwiritsidwa ntchito ngati binder, filimu wakale, ndi uphedwe.

Kapangidwe kalikonse kumasiyana pa cellulose iliyonse yochokera ku mtundu ndi digiri yolowa m'malo mwa njira yosinthira mankhwala. Kukhazikitsidwa kwa magulu awa ether kumapangitsa kuti katundu akhale ndi ether iliyonse ya pa cellulose, ndikuwapangitsa kukhala oyenera kusintha kwa mafakitale osiyanasiyana.
