Ethers ya Cellulose ni iki

Ether ya selile ni umuryango wimiti ikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima. Ibikomokaho byakozwe muburyo bwo guhindura imiti ya molekile ya selile kugirango itangire amatsinda atandukanye akora, bivamo ibintu byinshi byimikorere nibisabwa. Ether ya selile ikoreshwa cyane mu nganda nk'ubwubatsi, imiti, ibiryo, amavuta yo kwisiga, no kwita ku muntu bitewe n'imiterere inyuranye n'imiterere y'ingirakamaro. Hano hari ubwoko bumwe na bumwe bwa selile ethers hamwe nikoreshwa ryabyo:

1. Methyl Cellulose (MC):
   • Methyl selulose ikorwa no kuvura selile na methyl chloride.
   • Irashobora gushonga mumazi kandi ikora ibisubizo bisobanutse neza.
   • MC ikoreshwa nkibibyimbye, binder, na stabilisateur mubikoresho byubwubatsi (urugero, minisiteri ishingiye kuri sima, plastike ishingiye kuri gypsumu), ibikomoka ku biribwa, imiti, nibintu byita ku muntu.
2. Hydroxyethyl Cellulose (HEC):
   • Hydroxyethyl selulose ikomatanyirizwa mugukora selile hamwe na okiside ya Ethylene kugirango itangize amatsinda ya hydroxyethyl.
   • Irashobora gushonga mumazi kandi ikora ibisubizo bisobanutse, bifata neza hamwe nuburyo bwiza bwo kubika amazi.
   • HEC isanzwe ikoreshwa nkibibyimbye, ihindura imvugo, hamwe nogukora firime mugushushanya, ibifata, 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 nkibyimbye, binder, na rheologiya ihindura ibicuruzwa, imiti, imyenda, impapuro, nibikoresho bimwe byubaka.

Izi nimwe murimwe zikoreshwa cyane muri selile ya selile, buriwese ufite imitungo idasanzwe hamwe nibisabwa mubikorwa bitandukanye. Ubundi selile yihariye ya selile nayo irashobora kubaho, ijyanye nibisabwa byihariye mubikorwa bitandukanye.
