Kodi ma etheeuse ether ndi otani?

Cellulose Eders ndi gulu losiyanasiyana la ma polima omwe achokera ku cellulose, polysaczaczacal opezeka muzomera. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo kapangidwe ka zomangamanga, mankhwala opangira mankhwala, chakudya, zodzola, komanso chisamaliro chaumwini, chifukwa cha zinthu zawo zapadera komanso zothandiza. Nazi zina mwa mitundu yodziwika bwino ya cellulose ether:

1. Methyl cellulose (MC):
   • Methose Cellose imapangidwa pochiza cellulose ndi methyl chloride kubweretsa methl magulu am'mimba am'madzi oyambira pa celyulose.
   • Imasungunuka m'madzi ozizira ndikupanga njira zomveka, zothetsera ma viscous.
   • MC imagwiritsidwa ntchito ngati thicker, binder, ndi okhazikika m'magulu osiyanasiyana, kuphatikiza matope omanga (mwachitsanzo, matope a Sypsum, ndi zinthu zaumwini.
2. Hydroxyethyl cellulose (hec):
   • Hydroxyethyl cellulose imapangidwa ndi cellulose ndi ethylene oxide kuti ayambitse magulu a hydroxyathyl.
   • Imasungunuka m'madzi ozizira ndikupanga zomveka, zothetsera ma viscous ndi zida zabwino zamadzi.
   • Hec imagwiritsidwa ntchito ngati thicker, rhelology osintha, ndi wothandizira makanema mu utoto, zomata, zopangidwa ndi anthu, komanso mankhwala.
3. Hydroxypypyl methyl cellulose (hpmc):
   • Hydroxypropyl celyl cellulose imapangidwa poyambitsa hydroxypropyl ndi methyl magulu am'madzi am'madzi a cellulose.
   • Zimawonetsa katundu wofanana ndi methyl cellulose ndi hydroxethyl cellulose, kuphatikizapo kusungunuka madzi, kuthekera kwamafilimu, komanso kusungidwa kwamafilimu.
   • HPMC imagwiritsidwa ntchito kwambiri pomanga (mwachitsanzo, ma tile amaluma, okonda, mankhwala omwe amadzipangitsa okhawo), komanso mu mankhwala, komanso zinthu zosamalira pandekha.
4. Carboxymethyl cellulose (cmc):
   • Carboxymethyl cellulose imachokera ku celluluse pochiza ndi sodium hydroxide ndi monochloroortic acid kuti iyambitse magulu a carboxymethyl.
   • Imasungunuka m'madzi ndikupanga zomveka, zothetsera ma viscous muli bwino kwambiri, zokhazikika, komanso madzi osasunga madzi.
   • CMC imagwiritsidwa ntchito ngati thicker, binder, ndi rheologle osintha pazakudya, mankhwala, zolemba, pepala, ndi zida zomanga.
5. Ethyl cellulose (EC):
   • Cellulose ya ethyl imapangidwa ndi cellouse ndi enth chloride kuti iyambitse magulu a ethyl pamphepete mwa msana wa cellulose.
   • Ndizopanda thupi m'madzi koma sungunuka m'malo okhazikika monga ethanol ndi chloroform.
   • EC imagwiritsidwa ntchito ngati wothandizira makanema, binder, ndi zokutira mu mankhwala, zakudya, zodzola, komanso kugwiritsa ntchito mafakitale.

Awa ndi ena mwa mitundu yosiyanasiyana ya ethel ether, iliyonse yopereka katundu wapadera ndi mapindu ake pazosiyanasiyana. Cellulose ina yapadera imatha kukhalapo, yogwirizana ndi zofunikira zina m'mafakitale osiyanasiyana.
