Abahanga ba seliki ni iki

Abatanga selile ni umuryango wibice byimiti biva kuri selile, polymer karemano iboneka murukuta rwakagari yibimera. Aba bakomokaho baremwe binyuze mumiti ya molekile ya molekile kugirango bamenyekane amatsinda agenga imikorere, bikaviramo imitungo minini. Abashiraho selile bakunze gukoreshwa munganda nko kubaka, imiti, ibiryo, kwisiga, no kwita ku muntu ku giti cyabo bitewe n'imitungo yabo itandukanye n'imitungo yabo ifatika. Hano hari ubwoko bumwe na bumwe bwa bahanga muri selile nikoreshwa ryabo:

1. Methyl Cellulose (MC):
   • Methyl selile ikorwa no kuvura selile hamwe na methyl chloride.
   • Birashonje mumazi kandi bikora neza, ibisubizo bya viscous.
   • MC ikoreshwa nk'igituba, binder, kandi igaburira mu bikoresho by'ubwubatsi (urugero, minisiteri ishingiye kuri sima, abakinnyi ba gypsum), ibisigazwa by'ibiryo, n'ibikoresho by'ibiryo.
2. Hydroxyyeryl Cellulose (HEC):
   • HydroxyAythyl selile irakoreshwa mu gufatanya na selile hamwe na Ethylene oxide kumenyekanisha hydroxyyerthyl.
   • Birashonje mumazi kandi bikora 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.

Izi ni zimwe muri seliki zikoreshwa cyane na selile, buriwese ufite imitungo yihariye hamwe nibisabwa mubijyanye n'inganda zitandukanye. Ubundi buryo bwihariye bwa selile ashobora kandi kubaho, bihujwe nibisabwa muburyo butandukanye.
