Ni ubuhe buryo butandukanye bwa selire?

Abashiraho selile ni itsinda ritandukanye rya polymer bakomoka kuri selile, abagore benshi bafite ubutware buboneka mu bimera. Bakoreshwa cyane mu nganda zitandukanye, harimo kubaka, imiti, ibiryo, kwisiga, no kwita ku muntu ku giti cyabo, bitewe n'imitungo yabo idasanzwe. Hano harimwe muburyo busanzwe bwa selile ether:

1. Methyl Cellulose (MC):
   • Methyl selile ikorwa no kuvura selile na methyl chloride kugirango itange amatsinda ya methyl kuri selile.
   • Birashonje mumazi akonje nuburyo busobanutse, ibisubizo bya viscous.
   • MC ikoreshwa nkuwabyimbye, binder, na stabilizer muburyo butandukanye, harimo nibikoresho byubwubatsi (urugero, minisiteri ishingiye kuri sima, ibibuga byibiribwa, nibintu byibiryo, nibintu byibikoresho byawe.
2. Hydroxyyeryl Cellulose (HEC):
   • Hydroxyyeryl selile irakoreshwa mu gufatanya na selipi na Ethylene oxide kumenyekanisha hydroxyyerthyl ku mukongo wa selile.
   • Birashonje mumazi akonje kandi ikora neza, ibisubizo bya viscous hamwe numutungo wo kugumana amazi meza.
   • HEC ikoreshwa nkuwabyimbye, imiterere yurukundo, hamwe numukozi ushinzwe filming mu rupapuro, ahimbye, ibicuruzwa byita ku giti cye, na farumasi.
3. HydroxyPropyl Methyl Cellulose (HPMC):
   • HydroxyPropyl Methyl Cellulose itangwa no kumenyekanisha hydroxyPropyl na methyl matsinda ya methilose kuri selile.
   • Iyerekana imitungo isa na methyl selile na hydroxyAythyl selile, harimo no kwishyurwa n'amazi, ubushobozi bwo gushinga filime, no kugumana amazi.
   • HPMC ikoreshwa cyane mubikoresho byubwubatsi (urugero, tile imeza, ya sima ishingiye kuri sima, kwishyira hamwe byimiti), ndetse no muri farumasi, ibicuruzwa byibiribwa.
4. Carboxymethyl Cellulose (CMC):
   • Carboxymethyl selile ikomoka kuri selile ivura na sodium hydroxide na aside monochloroide na aside monochlorondoacetic kumutangiza amatsinda ya carboxymethyl.
   • Birashonje mumazi kandi bikora neza, ibisubizo bya viscous hamwe no kubyimba kwinshi, guhungabana, no kugumana amazi.
   • CMC ikunze gukoreshwa nkumubyimba, binder, hamwe nuburyo bwubwoko mubicuruzwa byibiribwa, imiti, imyenda, impapuro, hamwe nibikoresho bimwe byubwubatsi.
5. Ethyl Cellulose (EC):
   • Ethyl selile ikorwa mu gufata selile hamwe na selile chloride yo kumenyekanisha amatsinda ya Ethyl kuri selile.
   • Ntabwo yashonga mumazi ariko ishonje mubintu bya kama nka ethanol na chloroform.
   • EC ikunze gukoreshwa nkumukozi ushinzwe firime, binder, hamwe nibikoresho byo guhinga muri farumasi, ibicuruzwa byibiribwa, kwisiga, n'amavuta yo kwisiga, hamwe ninganda.

Ibi ni bimwe mu bwoko bukoreshwa cyane na selile, buri wese atanga imitungo idasanzwe n'inyungu kuri porogaramu zitandukanye. Ubundi buryo bwihariye bwa selile ashobora kandi kubaho, bujyanye nibisabwa mubisabwa muburyo butandukanye.
