Ni ubuhe bwoko busanzwe bwa selile ether? Ni ibihe bintu biranga?

Ether ya selile ni itsinda ritandukanye rya polymers ikomoka kuri selile, polyisikaride karemano iboneka mubihingwa. Zikoreshwa cyane mu nganda zitandukanye, zirimo ubwubatsi, imiti, ibiryo, no kwita ku muntu ku giti cye, bitewe n'imiterere yihariye kandi itandukanye. Hano hari ubwoko busanzwe bwa selile ether nibiranga:

1. Methyl Cellulose (MC):
   • Ibiranga:
     • Methyl selulose ni polymer yamazi ya elegitoronike ikomoka kuri selile mu kuyivura na methyl chloride.
     • Mubisanzwe nta mpumuro nziza, itaryoshye, kandi idafite uburozi, bigatuma ikoreshwa muburyo butandukanye bwa porogaramu.
     • MC yerekana uburyo bwiza bwo kubika amazi, bigatuma iba inyongera nziza ya minisiteri ishingiye kuri sima, plaque ishingiye kuri gypsumu, hamwe na tile.
     • Itezimbere gukora, gufatira hamwe, no gufungura umwanya mubikoresho byubwubatsi, itanga uburyo bworoshye bwo gukora no gukora neza.
     • Methyl selulose ikunze gukoreshwa nkibintu byongera umubyimba, stabilisateur, na emulisiferi mubicuruzwa byibiribwa, imiti, hamwe no kwisiga.
2. Hydroxyethyl Cellulose (HEC):
   • Ibiranga:
     • Hydroxyethyl selulose ikorwa mugukora selile hamwe na okiside ya Ethylene kugirango itangize amatsinda ya hydroxyethyl kumugongo wa selile.
     • Irashobora gushonga mumazi akonje kandi ikora ibisubizo bisobanutse, bifata neza hamwe nuburyo bwiza bwo kubika amazi.
     • HEC ikoreshwa cyane mubyimbye, ihindura imvugo, hamwe nogukora firime mubikorwa bitandukanye, birimo amarangi, ibifunga, ibicuruzwa byita kumuntu, hamwe na farumasi.
     • Mu bikoresho byubwubatsi, HEC itezimbere imikorere, irwanya sag, hamwe nubufatanye, bigatuma ikoreshwa muburyo bwa sima na gypsumu.
     • HEC itanga kandi imyitwarire ya pseudoplastique, bivuze ko ububobere bwayo bugabanuka mukibazo cyogosha, byoroshe gukoreshwa no gukwirakwira.
3. Hydroxypropyl Methyl Cellulose (HPMC):
   • Ibiranga:
     • Hydroxypropyl methyl selulose ni ether ya selile yakozwe mugutangiza hydroxypropyl 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 nkibikoresho bya tile, ibyuma bishingiye kuri sima, hamwe n’ibikoresho byo kwishyira hamwe kugirango bitezimbere imikorere, ifatanye, kandi ihamye.
     • Itanga umubyimba mwiza, guhuza, no gusiga amavuta muri sisitemu y'amazi kandi irahuza nibindi byongeweho bisanzwe bikoreshwa mubikorwa byo kubaka.
     • HPMC ikoreshwa kandi muri farumasi, ibikomoka ku biribwa, hamwe n’ibintu byita ku muntu nka stabilisateur, guhagarika ibikorwa, no guhindura viscosity.
4. Carboxymethyl Cellulose (CMC):
   • Ibiranga:
     • Carboxymethyl selulose ni selile ya selile ikomoka kuri selile mu kuyivura hamwe na hydroxide ya sodium na aside 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 nk'umuhinduzi mwinshi, uhuza, na rheologiya mu nganda zitandukanye, harimo ibiryo, imiti, imyenda, n'impapuro.
     • Mubikoresho byubwubatsi, CMC rimwe na rimwe ikoreshwa nkibikoresho bigumana amazi muri minisiteri ya sima na grout, nubwo bidakunze kugaragara cyane kuruta izindi ether ya selile bitewe nigiciro cyinshi kandi ntigahuzwa na sisitemu ya sima.
     • CMC ikoreshwa kandi muburyo bwa farumasi nkibikoresho bihagarika, ibinini bya tablet, hamwe na matrix igenzurwa.

Ubu ni bumwe mu bwoko busanzwe bwa selile ether, buri kimwe gitanga ibintu byihariye ninyungu kubikorwa bitandukanye. Mugihe uhitamo selulose ether kugirango ikoreshwe runaka, ibintu nkibishobora gukemuka, ubwiza, guhuza nibindi byongeweho, hamwe nibikorwa byifuzwa bigomba kwitabwaho.
