Malingaliro Oyambirira ndi Gulu la Etherse Ether

Cellulose ether ndi gulu losiyanasiyana la ma polima omwe achokera ku cellulose, polysacchabide mwachilengedwe amapezeka mu makhola a cell. Cellulose eder amagwiritsidwa ntchito kwambiri pamafakitale osiyanasiyana chifukwa cha zinthu zawo zapadera, zomwe zimaphatikizapo kukula, kusungidwa kwamadzi, kupanga mafilimu, komanso luso lokhazikika. Nayi malingaliro ndi magulu a cellulose a ether:

Malangizo Oyambirira:

1. Kapangidwe ka cellulose:
   • Cellulose amapangidwa kuti akubwereza mayunitsi a shuga omwe amalumikizidwa pamodzi ndi β (1 → 4) zomangira. Amapanga zazitali, maunyolo a mzere omwe amapereka chithandizo chomwe chimathandizidwa ndi zomera.
2. Kusintha:
   • Cellulose amapangidwa kudzera mu kusintha kwamankhwala kwa cellulose poyambitsa magulu a ethel (-Och3, -Och2Kooh, etc.)
3. Magwiridwe:
   • Kukhazikitsidwa kwa magulu a ether kumasintha mankhwala a cellulose, kupatsa cellulose emphakitadera monga kusubilidwe monga kukhazikika monga kusungunuka, kusungidwa kwamadzi, komanso mapangidwe a kanema.
4. Biodegradiity:
   • Cellulose elidgers okwera, kutanthauza kuti amatha kugawidwa ndi tizilombo tating'onoting'ono tomwe timayambitsa, zomwe zimayambitsa kuwonongeka kwa zinthu zosavulaza.

Gulu:

Cellulose eder amakhazikitsidwa kutengera mtundu wa magulu a ethel omwe adayambitsidwa pa cellulose molekyu ndi digiri yazolowa. Mitundu wamba ya cellose yophatikizika imaphatikizapo:

1. Methyl cellulose (MC):
   • Methyl cellulose imapangidwa poyambitsa methyl (-Och3) magulu a cellulose molekyulu.
   • Imasungunuka m'madzi ozizira ndi mitundu yowoneka bwino, mayankho a viscous. MC imagwiritsidwa ntchito ngati thicker, kukhazikika, ndi filimu yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana.
2. Hydroxyethyl cellulose (hec):
   • Hydroxyethyl cellulose imapezeka poyambitsa hydroxyethyl (-Och2ch2K2oh magulu pa cellulose molekyulu.
   • Imawonetsa madzi abwino kwambiri osakhazikika komanso zipatso zotukuka, kupanga kukhala koyenera kugwiritsa ntchito zotupa, zomatira, zodzola, zodzola, ndi mankhwala.
3. Hydroxypypyl methyl cellulose (hpmc):
   • Hydroxypropyl mealyul ndi wopopera wa methyl cellulose ndi hydroxypropyl cellulose.
   • Imaperekanso zofunikira kwambiri monga kusungunuka madzi, kuwongolera mafalo, ndi mapangidwe filimu. HPMC imagwiritsidwa ntchito kwambiri pomanga, mankhwala opangira mankhwala, komanso zinthu zosamalira anthu.
4. Carboxymethyl cellulose (cmc):
   • Carboxymethyl cellulose imapangidwa poyambitsa carboxymethyl (-Och2cooh magulu pa cellulose molekyulu.
   • Imasungunuka m'madzi ndikupanga ma viscous mayankho abwinobwino kwambiri ndikukhazikika. CMC imagwiritsidwa ntchito mu chakudya, mankhwala opangira mankhwala, ndi ntchito zamagetsi.
5. Ethyl hydroththyl cellulose (Ehec):
   • Ethyl hydrothyl cellulose imapezeka poyambitsa ethyl ndi hydroxyethyl magulu azinthu za cellulose.
   • Imawonetsa kusungidwa kwamadzi, kuyamba kukula, komanso zinthu zopanda pake poyerekeza ndi HeC. Ehec imagwiritsidwa ntchito popanga zinthu zomanga ndi zinthu zosamalira anthu.

Cellulose esla ndi ofunika ofunikira ndi mapulogalamu osiyanasiyana pamakampani osiyanasiyana. Kusintha kwawo kwa mankhwala kudzera mu kusintha kumapangitsa kuti azigwiritsa ntchito zinthu zosiyanasiyana, zimapangitsa kuti aziwonjezera zinthu zofunika kwambiri pakupanga utoto, zodzola, zodzola, mankhwala opangira chakudya, ndi zida zomangira. Kumvetsetsa malingaliro ndi magulu a cellose eder ndikofunikira posankha mtundu woyenera wa polymer yofunsira kwina.
