Ni ubuhe bwoko bwa Cellulose ether?

Ether ya selile ni itsinda ritandukanye rya polymers ikomoka kuri selile, polyisikaride karemano iboneka mubihingwa.Zikoreshwa cyane mu nganda zitandukanye, zirimo ubwubatsi, imiti, ibiryo, amavuta yo kwisiga, no kwita ku muntu ku giti cye, bitewe n'imiterere yihariye kandi itandukanye.Dore bumwe mu bwoko bukunze kugaragara bwa selile ether:

1. Methyl Cellulose (MC):
   • Methyl selulose ikorwa mukuvura selile hamwe na methyl chloride kugirango yinjize amatsinda ya methyl kumugongo wa selile.
   • Irashobora gushonga mumazi akonje kandi ikora ibisubizo bisobanutse neza.
   • MC ikoreshwa nkibibyimbye, bihuza, hamwe na stabilisateur muburyo butandukanye bwo gusaba, harimo ibikoresho byubwubatsi (urugero, minisiteri ishingiye kuri sima, plaque ishingiye kuri gypsumu), ibicuruzwa byibiribwa, imiti yimiti, nibintu byita kumuntu.
2. Hydroxyethyl Cellulose (HEC):
   • Hydroxyethyl selulose ihindurwamo reaction ya selile hamwe na okiside ya Ethylene kugirango yinjize amatsinda ya hydroxyethyl kumugongo wa selile.
   • Irashobora gushonga mumazi akonje kandi ikora ibisubizo bisobanutse, bifata neza hamwe nuburyo bwiza bwo kubika amazi.
   • HEC isanzwe ikoreshwa nkibyimbye, ihindura imvugo, hamwe nogukora firime mumarangi, ibifatika, ibicuruzwa byita kumuntu, hamwe na farumasi.
3. Hydroxypropyl Methyl Cellulose (HPMC):
   • Hydroxypropyl methyl selulose ikorwa mugutangiza hydroxypropyl hamwe na methyl mumatsinda ya selile.
   • Irerekana ibintu bisa na methyl selulose na hydroxyethyl selulose, harimo gukemura amazi, ubushobozi bwo gukora firime, no kubika amazi.
   • HPMC ikoreshwa cyane mubikoresho byubwubatsi (urugero, ibyuma bifata amatafari, imashini ishingiye kuri sima, ibyiyumanganya), ndetse no muri farumasi, ibikomoka ku biribwa, nibintu byita ku muntu.
4. Carboxymethyl Cellulose (CMC):
   • Carboxymethyl selulose ikomoka kuri selile mu kuyivura hamwe na sodium hydroxide na acide monochloroacetic kugirango itangize amatsinda ya carboxymethyl.
   • Irashobora gushonga mumazi kandi ikora ibisubizo bisobanutse, bisobanutse neza hamwe no kubyimba neza, gutuza, no kubika amazi.
   • Ubusanzwe CMC ikoreshwa nkibibyimbye, bihuza, na rheologiya ihindura ibicuruzwa, imiti, imyenda, impapuro, nibikoresho bimwe na bimwe byubaka.
5. Ethyl Cellulose (EC):
   • Ethyl selulose ikorwa mugukora selile hamwe na Ethyl chloride kugirango itangire amatsinda ya Ethyl kumugongo wa selile.
   • Ntishobora gushonga mumazi ariko irashobora gushonga mumashanyarazi nka Ethanol na chloroform.
   • EC isanzwe ikoreshwa nkibikorwa byo gukora firime, guhuza, hamwe nibikoresho byo muri farumasi, ibikomoka ku biribwa, kwisiga, no gukoresha inganda.

Ubu ni bumwe mu bwoko bukoreshwa cyane muri selile ya ether, buri kimwe gitanga ibintu byihariye ninyungu kubikorwa bitandukanye.Izindi selire yihariye ya selile irashobora kandi kubaho, ijyanye nibisabwa byihariye mubikorwa bitandukanye.
