Etar ya etar na selulose ether ni ubwoko bwibikomoka kuri ether bikoreshwa mu nganda zitandukanye, cyane cyane mubwubatsi no gutwikira. Mugihe basangiye bimwe mubijyanye no kuba amazi ya elegitoronike yamazi afite umubyimba no gutuza, hariho itandukaniro ryibanze hagati yabo, cyane cyane mubituruka hamwe nimiterere yimiti.
Ibinyamisogwe Ether:
1. Inkomoko:
- Inkomoko karemano: Ether ikomoka kuri krahisi, ni karubone ya hydrata iboneka mu bimera. Ibinyamisogwe bikunze gukurwa mubihingwa nk'ibigori, ibirayi, cyangwa imyumbati.
2. Imiterere yimiti:
- Ibigize Polymer: Ibinyamisogwe ni polysaccharide igizwe nibice bya glucose bihujwe na glycosidic. Ethers ya krahisi yahinduwe ikomoka kuri krahisi, aho amatsinda ya hydroxyl kuri molekile ya krahisi asimbuzwa amatsinda ya ether.
3. Gusaba:
- Inganda zubaka: Ethers ya krah ikoreshwa kenshi mubikorwa byubwubatsi nkinyongera mubicuruzwa bishingiye kuri gypsumu, minisiteri, nibikoresho bishingiye kuri sima. Bagira uruhare mu kunoza imikorere, gufata amazi, no gufatira hamwe.
4. Ubwoko rusange:
- Hydroxyethyl Starch (HES): Ubwoko bumwe busanzwe bwa krahisi ether ni hydroxyethyl krahisi, aho amatsinda ya hydroxyethyl yatangijwe kugirango ahindure imiterere ya krahisi.
Cellulose Ether:
1. Inkomoko:
- Inkomoko karemano: Cellulose ether ikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima. Nibintu byingenzi bigize urukuta rwibimera kandi bivanwa mumasoko nkibiti byimbaho cyangwa ipamba.
2. Imiterere yimiti:
- Ibikoresho bya Polymer: Cellulose ni polymer yumurongo ugizwe nibice bya glucose bihujwe na β-1,4-glycosidic. Ethers ya selile ni inkomoko ya selile, aho amatsinda ya hydroxyl kuri molekile ya selile yahinduwe hamwe na ether.
3. Gusaba:
- Inganda zubwubatsi: Ethers ya selulose isanga ikoreshwa cyane mubikorwa byubwubatsi, bisa na etarike. Zikoreshwa mubicuruzwa bishingiye kuri sima, ibifata bya tile, na minisiteri kugirango byongere amazi, gukora, no gufatira hamwe.
4. Ubwoko rusange:
- Hydroxyethyl Cellulose (HEC): Ubwoko bumwe busanzwe bwa selile ya selile ni hydroxyethyl selulose, aho amatsinda ya hydroxyethyl yatangijwe kugirango ahindure imiterere ya selile.
- Methyl Cellulose (MC): Ubundi bwoko busanzwe ni methyl selulose, aho amatsinda ya methyl yatangiriye.
Itandukaniro ry'ingenzi:
1. Inkomoko:
- Ibinyamisogwe ether ikomoka kuri krahisi, karubone ya hydrata iboneka mu bimera.
- Ether ya selile ikomoka kuri selile, igice kinini cyurukuta rwibimera.
2. Imiterere yimiti:
- Polimeri fatizo ya krahisi ether ni krahisi, polysaccharide igizwe na glucose.
- Polimeri fatizo ya selile ether ni selile, polymer umurongo ugizwe nibice bya glucose.
3. Gusaba:
- Ubwoko bwombi bwa ethers bukoreshwa mubikorwa byubwubatsi, ariko ibyifuzo byihariye nibishobora gutandukana.
4. Ubwoko rusange:
- Hydroxyethyl krahisi (HES) na hydroxyethyl selulose (HEC) ni ingero zibi bikomoka kuri ether.
mugihe ibinyamisogwe ether na selulose ether byombi ni polymer-soluble polymers ikoreshwa nkinyongera mubikorwa bitandukanye, inkomoko yabyo, polymer shingiro, hamwe nimiterere yihariye ya chimique iratandukanye. Itandukaniro rishobora guhindura imikorere yabo muburyo bwihariye.
