Gusenya selile ya selile irashobora kuba inzira igoye bitewe nimiterere yihariye yimiti nimiterere. Ether ya selile ni polymer zishonga mumazi zikomoka kuri selile, polisikaride isanzwe iboneka murukuta rw'utugingo ngengabuzima. Zikoreshwa cyane mu nganda zitandukanye nka farumasi, ibiryo, imyenda, nubwubatsi bitewe nuburyo bwiza bwo gukora firime, kubyimba, guhambira, no gutuza.
1. Gusobanukirwa Ethers ya Cellulose:
Ethers ya selile ni inkomoko ya selile, aho amatsinda ya hydroxyl asimbuwe igice cyangwa asimbuwe rwose na matsinda ya ether. Ubwoko bukunze kuboneka harimo methyl selulose (MC), hydroxypropyl selulose (HPC), hydroxyethyl selulose (HEC), na carboxymethyl selulose (CMC). Buri bwoko bufite imiterere yihariye bitewe nurwego n'ubwoko bwo gusimbuza.
2. Ibintu bigira ingaruka kubikemura:
Ibintu byinshi bigira ingaruka kuri solubose ethers:
Impamyabumenyi yo gusimbuza (DS): DS yo hejuru muri rusange itezimbere gukemura kuko byongera hydrophilicity ya polymer.
Uburemere bwa molekuline: Uburemere buke bwa selile ya selile irashobora gusaba igihe kinini cyangwa imbaraga zo gusesa.
Ibyiza bya Solvent: Umuti ufite polarite nyinshi hamwe nubushobozi bwo guhuza hydrogène, nkamazi hamwe nudukoko twa organic organic solvent, mubisanzwe bigira akamaro mugushonga ethers ya selile.
Ubushyuhe: Kongera ubushyuhe birashobora kongera imbaraga mu kongera imbaraga za kinetic ya molekile.
Imyivumbagatanyo: Imyitozo ya mashini irashobora gufasha guseswa mukongera umubano hagati yumuti na polymer.
pH: Kuri ethers zimwe na zimwe za selile nka CMC, pH irashobora kugira ingaruka zikomeye kubishobora kubera amatsinda ya carboxymethyl.
3. Umuti wo gusesa:
Amazi: Ethers nyinshi ya selile irashobora gushonga byoroshye mumazi, bigatuma iba igisubizo cyibanze kubikorwa byinshi.
Inzoga: Ethanol, methanol, na isopropanol zikoreshwa cyane mu gufatira hamwe kugira ngo zongere imbaraga za eteri ya selile, cyane cyane kubafite amazi make.
Organic Solvents: Dimethyl sulfoxide (DMSO), dimethylformamide (DMF), na N-methylpyrrolidone (NMP) akenshi bikoreshwa mubikorwa byihariye aho bikenewe cyane.
4. Uburyo bwo gusesa:
Korohereza Byoroheje: Kubisabwa byinshi, gusa gukurura selile ya selile mumashanyarazi ikwiye kubushyuhe bwibidukikije birahagije kugirango isenyuke. Nyamara, ubushyuhe bwo hejuru nibihe birebire bishobora gukenerwa kugirango bisenywe burundu.
Gushyushya: Gushyushya ibishishwa cyangwa imvange ya polymer irashobora kwihutisha guseswa, cyane cyane kuburemere buke bwa molekuline ya selile cyangwa se abafite ubushobozi buke.
Ultrasonication: Imyiyerekano ya Ultrasonic irashobora kongera isesemi mukurema cavitation bubles zitera kumeneka kwa polymer hamwe no kunoza kwinjira.
Gukoresha ibishashara: Guhuza amazi n'inzoga cyangwa ibindi bikoresho bya polar organique birashobora kunoza imbaraga, cyane cyane kuri ether ya selile ifite amazi make.
5. Ibitekerezo bifatika:
Ingano ya Particle: Ifu nziza ya selulose ethers irashonga byoroshye kuruta ibice binini bitewe nubuso bwiyongereye.
Gutegura ibisubizo: Gutegura selile ya ether ibisubizo muburyo butandukanye, nko gukwirakwiza polymer mugice cyumuti mbere yo kongeramo ibisigaye, birashobora gufasha kwirinda guhuzagurika no kwemeza ko bisenyuka kimwe.
pH Guhindura: Kuri ether ya selile yunvikana kuri pH, guhindura pH yumuti birashobora kunoza gukomera no gutuza.
Umutekano: Umuyoboro umwe ukoreshwa muguhagarika selile ya selile irashobora guteza ubuzima bwiza numutekano. Guhumeka neza hamwe nibikoresho byokwirinda bigomba gukoreshwa mugihe ukoresha ibyo bishishwa.
6. Ibitekerezo byihariye byo gusaba:
Imiti ya farumasi: Ethers ya selile ikoreshwa cyane muburyo bwa farumasi kugirango irekurwe neza, guhambira, no kubyimba. Guhitamo uburyo bwo gukemura no gusesa biterwa nibisabwa byihariye.
Ibiryo: Mugukoresha ibiryo, selile ya selile ikoreshwa nkibibyimbye, stabilisateur, hamwe nabasimbuye amavuta. Umuti uhuye n’amabwiriza y’ibiribwa ugomba gukoreshwa, kandi uburyo bwo gusesa bugomba kuba bwiza kugirango ibicuruzwa bibe byiza.
Ubwubatsi: Ether ya selile ikoreshwa mubikoresho byubwubatsi nka minisiteri, grout, na adhesives. Guhitamo gukemura no gusesa ibintu nibyingenzi kugirango ugere kubwiza bwifuzwa nibikorwa.
7. Icyerekezo kizaza:
Ubushakashatsi kumashanyarazi mashya hamwe nubuhanga bwo gusesa bikomeje guteza imbere urwego rwa chimie selile. Icyatsi kibisi, nka CO2 ndengakamere na ionic fluid, bitanga ubundi buryo hamwe nibidukikije bigabanuka. Byongeye kandi, iterambere muri polymer injeniyeri na nanotehnologiya rishobora kuganisha kumajyambere ya selile ya selile hamwe no gukemura neza hamwe nibikorwa biranga.
iseswa rya selile ya selile ni inzira zinyuranye ziterwa nibintu bitandukanye nkimiterere ya polymer, imiterere ya solvent, hamwe nubuhanga bwo gusesa. Gusobanukirwa nibi bintu no guhitamo ibishishwa hamwe nuburyo bukwiye ningirakamaro kugirango ugere ku gusesa neza no kunoza imikorere ya selile ya selile mubikorwa bitandukanye.
