Ether Ether (GC) ni icyiciro cyibikomokaho byabonetse kubijyanye na selile. Cellulose nicyo kintu nyamukuru cyinkike za seruki, kandi abahanga muri selile ni urukurikirane rwa polymers rwatangarijwe no gutondekanya amatsinda amwe n'amwe ya hydroxyl (-Oh) muri selile. Byakoreshejwe cyane mubice byinshi nkibikoresho byubaka, imiti, kwisiga, kwisiga, nibindi, kandi bikoreshwa cyane mu nganda zitandukanye kubera imiti yabo idasanzwe yumubiri nuburozi.
1.. Ibyiciro bya selire
Abakoresha TOLULULOULOSE barashobora kugabana kugabana kugabana gutandukana ukurikije ubwoko bwabasimbuye mumiterere yimiti. Icyiciro rusange gishingiye ku itandukaniro mubasimbuye. Abahanga muri seliki basanzwe ni ibi bikurikira:
Methyl selile (mc)
Methyl selile ikorwa no gusimbuza hydroxyl igice cya molekile ya selile hamwe na methyl (-CH₃). Ifite ubwinshi, ifiti ifite filime kandi ifatanye kandi ikunze gukoreshwa mubikoresho byo kubaka, amatara, imiti ninganda zibiribwa.
HydroxyPropyl Methylcellse (HPMC)
HydroxyPropyl methylcellse ni ubuvuzi busanzwe, bukoreshwa cyane mubikoresho byubaka, imiti, imiti ya buri munsi hamwe nibiribwa byibiribwa bitewe n'amazi meza no gutuza kw'amazi. HPMC ni selile ya Noineti yitonze hamwe numutungo wo kugumana amazi, kubyimba no gutuza.
Carboxymethyl Cellulose (CMC)
Carboxymethyl selile ni ether ya selile ya aiyoni yabaye mutangiza amatsinda ya carboxymethyl (-ch₂cooh) amatsinda muri molekile. CMC ifite amazi meza kandi akoreshwa kenshi nkumubyimba, stabilizer na guhagarika umukozi. Ifite uruhare runini mubiryo, imiti no kwisiga.
Ethyl selile (EC)
Ethyl selile iraboneka mugusimbuza Hydroxyl Itsinda muri selile hamwe na Ethyl (-ch₂ch₃). Ifite hydrophobicity nziza kandi ikunze gukoreshwa nkamashyaka yo gukwirakwiza firime kandi agenzurwa ibikoresho byo kurekura ibikoresho munganda za farumasi.
2. Imitungo yumubiri na shimi ya selile
Imitungo yumubiri na shimi ya selile ya selile ifitanye isano rya bugufi nibintu nkubwoko bwa selile, ubwoko bwumusimbuzi nurwego rwo gusimbuza. Imitungo yayo nyamukuru ikubiyemo ibi bikurikira:
Amazi yoroheje no Kudakemurwa
Abashiraho selile benshi bafite amazi meza kandi barashobora gushonga mumazi akonje cyangwa ashyushye kugirango bakore igisubizo cya colloidare. Kurugero, HPMC, CMC, nibindi irashobora gushonga byihuse mumazi kugirango akore igisubizo kinini, gikoreshwa cyane mubisabwa nibisabwa byimikorere nko kubyimba, guhagarikwa, no gushiraho firime.
Kubyimba no gukora firime
Abahanga ba selile bafite imitungo myiza yijimye kandi irashobora kongera ubukwe bwibisubizo bitangaje. Kurugero, ongeraho HPMC yo kubaka ibikoresho birashobora guteza imbere plastike no gukorana na minisiteri no kuzamura imitungo yo kurwanya. Muri icyo gihe, bahanganye na selile bafite imitungo myiza ya firime kandi irashobora gukora film yo kurinda film hejuru yibintu, bityo bikoreshwa cyane mubijyanye no kutwika no guhuza ibiyobyabwenge.
Kugumana amazi no gutuza
Abahanga ba selile bafite nabo bafite ubushobozi bwiza bwo kugumana amazi, cyane cyane mumwanya wibikoresho byubaka. Abahanga ba selile bakunze gukoreshwa mu kuzamura imitako y'amazi kuri minisiteri, kugabanya ibitaramo bya minikari, kandi bakagura ubuzima bwa minisiteri. Mu gace k'ibiribwa, CMC nayo ikoreshwa nka Humectant yo gutinza ibiryo byuma.
Imiti
Abahanga muri selile bagaragaza ko imiti myiza yimiti muri aside, alkali na electrolyte ibisubizo, kandi irashobora kubungabunga imiterere n'imikorere muburyo butandukanye bwibidukikije. Ibi bibafasha gukoreshwa muburyo butandukanye bwinganda nta kwivanga mubindi biti.
3. Inzira yumusaruro wa selile
Umusaruro wa selile wateguwe cyane cyane utegurwa cyane no guhinduranya ibyangiritse bya selile karemano. Inzira yibanze Intambwe zirimo kuvura alkanalisation ya selile, reaction yabuze, kwezwa, nibindi
Kuvura alkalisation
Ubwa mbere, selile isanzwe (nka pamba, ibiti, nibindi) byanditswe kugirango uhindure hydroxyl igice cya selile muri selile.
Guhura
Ubugari bwa Celilose nyuma ya alkalisation yitabira umukozi ukurikira (nka methyl chloride, okiside ya proploride, nibindi) kubyara selile. Ukurikije uko ibintu bimeze, ubwoko butandukanye bwa bahanganye na selile burashobora kuboneka.
Kweza no gukama
Ether ether yabyaye kubisubizo byezwa, yogejwe kandi yumye kugirango ibone ifu cyangwa ibicuruzwa bya granular. Isuku nibikorwa byumubiri byibicuruzwa byanyuma birashobora kugengwa nikoranabuhanga rikurikira.
4. Gusaba imirima ya selile ether
Kubera imitungo idasanzwe kandi yimiti ya ba enere ya selile, bakoreshwa cyane mu nganda nyinshi. Icyiciro nyamukuru gisaba ni ibi bikurikira:
Ibikoresho byo kubaka
Mu rwego rw'ibikoresho byo kubaka, abahanga muri selire bakoreshwa cyane cyane nk'abarimbyi n'amazi bamazi amazi ashinzwe sima na cemer na gypsum. Abayobozi ba selire nka HPMC na MC barashobora kunoza imikorere yubwubatsi ya minisiteri, kugabanya igihombo cyamazi, bityo bakazamura imyidagaduro no kurwanya.
Imiti
Mu nganda z'imiti, bahanganye na selile bakoreshwa cyane nk'abakozi bashinzwe ibiyobyabwenge, bahimbye ibinini, n'ibikoresho bigenzurwa. Kurugero, HPMC ikoreshwa kenshi gutegura ibiyobyabwenge bya firime kandi bifite ingaruka nziza zo kurekura.
Ibiryo
CMC ikunze gukoreshwa nkuwabyimbye, Emalifier, na stabilizer mu nganda zibiribwa. Bikoreshwa cyane mubinyobwa, ibicuruzwa byamata, nibicuruzwa bitetse, kandi birashobora kunoza uburyohe nubushake bwibiryo.
Kwisiga n'imiti ya buri munsi
Abashiraho selile bakoreshwa nk'abakira no kumarana n'intangarugero mu kwisiga n'imiti ya buri munsi, bishobora gutanga ubudahariko. Kurugero, HPMC ikunze gukoreshwa mubicuruzwa nka methio kubaha virusi itera imbaraga ningaruka zihamye.
IHURIRO
Mu nganda zifatanije, abahanga muri seliki bakoreshwa nk'abarimbyi, abahinzi ba filime, no guhagarika abakozi, bashobora kongera imikorere yo kubaka, kunoza urwego rwiza.
5. Iterambere ry'ejo hazaza EREHORE
Hamwe no gukenera kwiyongera mu kurengera ibidukikije, ether ether, nk'ibihimbano bya kamere rusange, bifite ibyiringiro bigari. Biodegrafiya, kongerwa no guhuzagura bituma biteganijwe ko bizakoreshwa cyane mumirima yibikoresho bibisi, ibikoresho bitesha agaciro nibikoresho byubwenge mugihe kizaza. Byongeye kandi, ether ether ifite kandi ubundi bushakashatsi nubushobozi bwiterambere muburyo bwongeweho agaciro gakomeye nkibisanzwe hamwe nibikoresho byateye imbere.
Nkibicuruzwa byingenzi byimiti, ether ether ifite agaciro gakomeye. Hamwe no kubyimba kwinshi, kugumana amazi, gushiraho film hamwe nubushyuhe bwiza bwa chimique, bigira uruhare rudakosowe mumirima myinshi nko kubaka, kuvura, nibiryo. Mu bihe biri imbere, hamwe no gutera imbere kw'ikoranabuhanga no guteza imbere ibitekerezo byo kurinda ibidukikije, ibyifuzo bya selile Ether bizaba byinshi kandi bigatanga umusanzu mu kuzamura iterambere rirambye ry'inganda zihoraho z'inganda zihoraho z'inganda zihoraho z'inganda zihoraho z'inganda zinyuranye z'inganda zihamye.
