1. Ubwoko bwibicuruzwa nibisobanuro
Hariho ubwoko bwinshi bwibicuruzwa bya selile, kandi ubwoko butandukanye bufite itandukaniro rigaragara mubikorwa. Ethers isanzwe ya selile irimo hydroxypropyl methylcellulose (HPMC), hydroxyethyl selulose (HEC), carboxymethyl selulose (CMC), nibindi.
HPMC: Ahanini ikoreshwa mubikoresho byubaka, ubuvuzi, ibiryo nizindi nzego, hamwe no kubyimba neza, gukora firime, kubika amazi no gufatira hamwe.
HEC: Ikoreshwa cyane mu gutwikira, gufatisha, kumesa, hamwe no kubyimba neza, gutuza no gukama amazi.
CMC: Ikoreshwa cyane mubiribwa, imiti ya buri munsi ninganda zikora impapuro, kandi ifite ingaruka nziza kandi zifatika.
Mugihe uhisemo ubwoko bukwiye bwa selulose ether, birakenewe gusobanura umurima wabyo, ibisabwa mumikorere nibisobanuro byihariye, nka viscosity, urwego rwo gusimbuza, nibindi.

Ubukonje bwibicuruzwa bya selulose ether nigikorwa cyingenzi cyerekana imikorere, izagira ingaruka itaziguye kumiterere ya rheologiya, kwikemurira no gukoresha ingaruka zibicuruzwa. Ubwiza bwa selulose ether burashobora guhinduka ukurikije ibisabwa:
Ether ya viscosity selulose ether: ikoreshwa cyane mubisabwa bisaba ingaruka zikomeye zo kubyimba no kugumana amazi menshi, nko kubaka minisiteri. Ubu bwoko bwa selulose ether burashobora kongera amazi no gukora neza kubintu.
Ubukonje buke bwa selulose ether: ahanini ikoreshwa mubisabwa bifite imbaraga nyinshi zo gukenera no gutembera neza, nka coatings, detergent hamwe nindi mirima, ifasha kunoza amazi no gutembera neza.
Iyo hejuru cyane, niko bigoye gushonga. Kubwibyo, guhitamo ibicuruzwa bifite ubukonje bukwiye bisaba gutekereza cyane kubikorwa byubwubatsi cyangwa gutunganya nibikorwa bikenerwa nibicuruzwa byanyuma.
3. Impamyabumenyi yo gusimbuza ubwoko
Imiterere yimiti nibisabwa biranga selile ether biterwa nubwoko numubare wamatsinda asimbuye. Urwego rwo gusimbuza rwerekana urwego amatsinda ya hydroxyl muri molekile ya selile asimburwa, ubusanzwe agaragazwa nkumubare mpuzandengo wibisimburanya kuri glucose (urugero, hydroxypropyl, methyl, carboxymethyl, nibindi). Ubwoko nurwego rwo gusimbuza insimburangingo bigira ingaruka zitaziguye, ubushobozi bwo kubyimba no kurwanya umunyu wa selile ya ether.
Urwego rwo hejuru rwo gusimbuza selile ether: ifite amazi meza hamwe nubushyuhe buke bwa gelation, bikwiranye nibisabwa bisaba amazi menshi cyangwa gukora ubushyuhe buke.
Urwego rwo hasi rwo gusimbuza selulose ether: irashobora kugira ubushyuhe bwa gel hamwe no kutagira amazi meza, bikwiranye nimirima idasanzwe nko gushakisha peteroli cyangwa ibidukikije byubushyuhe bwinshi.
Byongeye kandi, insimburangingo zitandukanye zizatanga selile ya ethers ya selile itandukanye ya chimique, nka carboxymethyl selulose ifite umunyu urwanya umunyu hamwe nigisubizo gihamye.
4. Gukemura
Ibicuruzwa byiza bya selile nziza ya ether bigomba kugira ibisubizo byiza kugirango bishoboke vuba kandi bibe igisubizo gihamye mugihe cyo gukoresha. Gukemura ibibazo biterwa nibintu nkibisimbuza, ubwiza, nubunini bwibicuruzwa. Ether nziza ya selile igomba kuba ishobora gushonga vuba mumazi akonje kugirango ikore igisubizo kimwe, kandi ntibishobora guhurira hamwe cyangwa gutatana.
Ibipimo nkigipimo cyo guseswa nigisubizo kiboneye hamwe nubukonje buhamye bigira ingaruka kumikorere yibicuruzwa mubikorwa bifatika. Kubwibyo, mugihe uhitamo selulose ether, birakenewe kwemeza niba ifite solubile nyinshi kandi itajegajega muburyo bukoreshwa.
5. Ingano y'ibice
Ingano yubunini bwa selile ether nayo izagira ingaruka ku gipimo cyayo cyo gusesa no gukoresha ingaruka. Ether-selile nziza ya selile mubisanzwe irashonga vuba kandi igatatana cyane, bikwiranye nubwubatsi bwihuse cyangwa gutunganywa byihuse, mugihe ether-selile-selile selile irashobora gushonga buhoro, ariko birashobora kuramba mubikorwa bimwe.
Mubisanzwe, ingano yubunini bwa selulose ether yerekanwa kumurongo wibicuruzwa, kandi abayikora barashobora kandi guhitamo ibicuruzwa byubunini butandukanye ukurikije abakoresha bakeneye guhuza nibikorwa bitandukanye.
6. Isuku nubuziranenge bwibicuruzwa
Ubwiza bwa selulose ether bugira ingaruka muburyo butaziguye, cyane cyane mubice bifite ubuziranenge nkibiribwa nubuvuzi, ubuziranenge bwibicuruzwa nigipimo cyingenzi. Ether-isuku nyinshi ya selile igomba kuba irimo umwanda muke kandi ntabwo bizagira ingaruka mbi kumabara, impumuro, uburyohe nibikorwa byanyuma.
Mubyongeyeho, ubuziranenge bwibicuruzwa nabwo ni ngombwa. Kugirango hamenyekane neza ibicuruzwa mubice bitandukanye, birakenewe guhitamo uruganda rukora sisitemu yo kugenzura ubuziranenge. Iterambere ryigihe kirekire rirashobora kugabanya itandukaniro rishobora kubaho mugihe cyo gukoresha, bityo bigatuma ibisubizo bihoraho buri gihe.
7. Impamyabumenyi hamwe na serivisi
Guhitamo selile yizewe itanga ether nayo irakomeye. Isoko ryo mu rwego rwo hejuru ntirigomba kugira ubushobozi bwiza bwo gukora no kugenzura ubuziranenge, ahubwo rishobora no gutanga ubufasha bwa tekiniki bwumwuga na serivisi nyuma yo kugurisha.
Impamyabushobozi y'abatanga isoko: Sobanukirwa n'umusaruro utanga ibicuruzwa, uburambe mu nganda, imiterere y'icyemezo (nk'icyemezo cya ISO, n'ibindi) kandi niba gifite ibyangombwa bisabwa mu bijyanye.
Inkunga ya tekiniki: Abatanga isoko nziza bagomba kuba bashobora gutanga amabwiriza yo gusaba ibicuruzwa ukurikije ibyo abakiriya bakeneye kugirango barebe ko abakiriya bashobora gukoresha ibicuruzwa neza kandi bakagera kubisubizo byiza.
Serivisi nyuma yo kugurisha: Ni ngombwa kandi guhitamo abaguzi bashobora gutanga ubufasha bwa tekiniki mugihe gikwiye.
8. Igiciro nigiciro-cyiza
Igiciro cyibicuruzwa bya selile biratandukana bitewe nubwiza, ikirango, nibisobanuro. Mugihe uhisemo ibicuruzwa, ntugomba gukurikirana gusa igiciro gito, ariko ugomba gutekereza cyane kubikorwa byacyo, ingaruka zikoreshwa, no gukoresha ikiguzi. Rimwe na rimwe, nubwo ethers nziza ya selile nziza cyane ihenze cyane, irerekana imikorere myiza mugukoresha, irashobora kuzamura umusaruro cyangwa kuzamura ubwiza bwibicuruzwa, kandi bifite igiciro kinini.
Mugihe ushakisha ibicuruzwa byiza bya selulose ether, ugomba gusuzuma witonze ubwoko bwibicuruzwa, ubwiza, urugero rwo gusimbuza, gukemuka, ingano yingirakamaro, ubuziranenge, hamwe nubuziranenge buhamye ukurikije ibisabwa nyirizina, kandi ugasuzuma ibyangombwa na serivisi bitanga isoko. Gusa mugereranije byimazeyo imikorere nigiciro-cyibicuruzwa bitandukanye dushobora kubona ethers ya selile ikwiye kugirango ihuze ibikenerwa ninganda zihariye hamwe nuburyo bukoreshwa.
