Hydroxyethyl Methyl Cellulose (HEMC)ni selile yingenzi ya selile kandi ni iyindi selile ya ionic selile. HEMC iboneka muguhindura imiti hamwe na selile naturel nkibikoresho fatizo. Imiterere yacyo irimo hydroxyethyl na methyl insimburangingo, bityo ikaba ifite imiterere yihariye yumubiri nubumashini kandi ikoreshwa cyane mubikoresho byubaka, gutwikira, imiti ya buri munsi, ubuvuzi nizindi nzego.
1. Imiterere yumubiri nubumara
Ubusanzwe HEMC ni ifu yera cyangwa yera yera cyangwa granules, byoroshye gushonga mumazi akonje kugirango bibe igisubizo kibonerana cyangwa cyoroshye cyane. Ibintu nyamukuru biranga harimo:
Gukemura: HEMC irashobora gushonga vuba mumazi akonje, ariko ikagira imbaraga nke mumazi ashyushye. Ububasha bwacyo hamwe nubwiza bwimpinduka hamwe nubushyuhe bwubushyuhe nagaciro ka pH.
Ingaruka yibyibushye: HEMC ifite ubushobozi bukomeye bwo kubyimba mumazi kandi irashobora kongera neza ubwiza bwumuti.
Kubika amazi: Ifite imikorere myiza yo gufata amazi kandi irashobora gukumira gutakaza amazi mubikoresho.
Umutungo ukora firime: HEMC irashobora gukora firime imwe ibonerana hejuru hamwe nubukomezi nimbaraga.
Amavuta: Kubera imiterere yihariye ya molekile, HEMC irashobora gutanga amavuta meza.
2. Gahunda yumusaruro
Ibikorwa byo gukora HEMC bikubiyemo ahanini intambwe zikurikira:
Alkalisation: selile isanzwe ivurwa mugihe cya alkaline kugirango ikore selile.
Imyitwarire ya Etherification: Mugushyiramo methylating agent (nka methyl chloride) hamwe na hydroxyethylating agent (nka okiside ya Ethylene), selile ikora reaction ya etherification kubushyuhe bwihariye nigitutu.
Nyuma yubuvuzi: Ibicuruzwa bivamo ibicuruzwa bivamo kutabogama, gukaraba, gukama, no kumenagura kugirango ubone amaherezoHEMCibicuruzwa.
3. Ahantu h'ingenzi hasabwa
. Irashobora kunoza ubwiza, kubika amazi hamwe no kurwanya kugabanuka kw ibikoresho byubwubatsi, kongera igihe cyo gufungura, bityo bikanoza imikorere yubwubatsi.
. Mubyongeyeho, irashobora gutanga ibintu byiza byerekana firime, bigatuma irangi risa neza kandi neza.
. Bitewe n'umutekano wacyo mwinshi hamwe na biocompatibilité, ikoreshwa kenshi mubicuruzwa nk'ibitonyanga by'amaso, koza mu maso, n'amavuta yo kwisiga.
.
4. Ibyiza no kurengera ibidukikije
HEMC ifite ibinyabuzima byinshi kandi birinda ibidukikije kandi ntibizatera umwanda igihe kirekire ibidukikije. Muri icyo gihe, ntabwo ari uburozi kandi butagira ingaruka, ntibitera uruhu rwabantu nuduce twinshi, kandi byujuje ibisabwa byo kurengera ibidukikije n’iterambere rirambye.
5. Amahirwe yisoko niterambere ryiterambere
Hamwe niterambere ryinganda zubaka ninganda zikora imiti ya buri munsi, isoko rya HEMC rikomeje kwiyongera. Mu bihe biri imbere, mugihe abantu bitaye cyane kubidukikije byangiza ibidukikije no kurushaho kunoza imikorere, HEMC izakoreshwa cyane mubice bitandukanye. Byongeye kandi, ubushakashatsi niterambere ryibicuruzwa bishya bya HEMC (nkubushyuhe bwo hejuru birwanya nubwoko bwihuse) bizanateza imbere ikoreshwa ryabyo murwego rwohejuru.
Nka mikorere myinshi kandi ikora cyane ya selile ether,hydroxyethyl methylcellulose (HEMC)igira uruhare runini mubwubatsi, gutwikira, ubuvuzi nizindi nzego hamwe nimiterere yihariye yumubiri nubumara. Hamwe niterambere ryubumenyi n’ikoranabuhanga no kwagura ibikorwa, HEMC izagira uruhare runini mu nganda zigezweho kandi itange inkunga ikomeye mu iterambere ry’inganda zijyanye.
