Ibyiza bya Hydroxyethyl Methyl Cellulose

Hydroxyethyl Methyl Cellulose (HEMC) ni inkomoko ya polymer naturel ya selile. Ni amazi ashonga polymer yakozwe nyuma yo guhindura imiti kandi ifite uburyo bwinshi bwo kuyikoresha. Nka eferi yingenzi ya elegitoronike ya elegitoronike, ifite ibintu byinshi bidasanzwe byumubiri nubumara kandi ikoreshwa cyane mubwubatsi, gutwikira, kwisiga, ibiryo nubuvuzi.

1. Imiterere yimiti nibigize
Hydroxyethyl methyl selulose ni selile yahinduwe ikorwa na etherification reaction ya selile hamwe na okiside ya Ethylene (epoxy) na methyl chloride nyuma yo kuvura alkali. Imiterere yimiti irimo skeleton ya selile hamwe ninsimburangingo ebyiri, hydroxyethyl na mikorerexy. Kwinjiza hydroxyethyl birashobora kunoza amazi yacyo, mugihe kwinjiza mikorobe bishobora guteza imbere hydrophobicity, bigatuma bigira igisubizo cyiza kandi bikora neza.

2. Gukemura
Hydroxyethyl methyl selulose ni ether idafite ionic selulose ether ifite amazi meza, ashobora gushonga mumazi akonje namazi ashyushye. Ntabwo ikora hamwe na ion mumazi iyo ishonga, bityo ikagira imbaraga nziza cyane mubihe bitandukanye byamazi. Igikorwa cyo gusesa gisaba ko gikwirakwizwa mu mazi akonje mbere, kandi nyuma yigihe cyo kubyimba, igisubizo kimwe kandi kiboneye kibaho buhoro buhoro. Mu mashanyarazi kama, HEMC yerekana gukemura igice, cyane cyane mumashanyarazi ya polar cyane nka Ethanol na Ethylene glycol, ishobora kuyasesa igice.

3. Viscosity
Ubukonje bwa HEMC nimwe mubintu byingenzi byingenzi kandi bikoreshwa cyane mubyimbye, guhagarikwa no gukora firime. Ubukonje bwacyo burahinduka hamwe nimpinduka yibitekerezo, ubushyuhe nigipimo cyogosha. Muri rusange, ubwiza bwigisubizo bwiyongera cyane hamwe no kwiyongera kwibisubizo. Igisubizo gifite kwibanda cyane cyerekana ububobere buke kandi burakwiriye gukoreshwa nkibibyimbye kubikoresho byubaka, ibifuniko hamwe nibifatika. Mubipimo byubushyuhe runaka, ubwiza bwumuti wa HEMC buragabanuka hamwe nubushyuhe bwiyongera, kandi uyu mutungo utuma bikenerwa mubikorwa byinganda mubihe bitandukanye.

4. Guhagarara neza
Hydroxyethyl methylcellulose yerekana ubushyuhe bwiza bwumuriro mubushyuhe bwinshi kandi ifite ubushyuhe bwinshi. Mubisanzwe, mugihe cy'ubushyuhe bwo hejuru (nko hejuru ya 100 ° C), imiterere ya molekile irahagaze neza kandi ntabwo byoroshye kubora cyangwa gutesha agaciro. Ibi bituma HEMC ikomeza kubyimba, kubika amazi no guhuza imiterere yubushyuhe bwo hejuru mubikorwa byubwubatsi (nkibikorwa byo kumisha minisiteri) bitagize ingaruka nziza cyane kubera ihindagurika ryubushyuhe.

5. Kubyimba
HEMC ifite imiterere myiza yo kubyimba kandi ni umubyimba mwiza cyane ukoreshwa cyane muri sisitemu zitandukanye. Irashobora kongera neza ubwiza bwibisubizo byamazi, emulisiyo hamwe nuguhagarikwa, kandi bifite imiterere myiza yo kogosha. Ku gipimo gito cyogosha, HEMC irashobora kongera cyane ubwiza bwa sisitemu, mugihe ku gipimo cyogosha cyinshi igaragaza ububobere buke, bufasha kunoza imikorere yimikorere mugihe cyo kuyisaba. Ingaruka yabyimbye ntabwo ijyanye no kwibanda gusa, ahubwo inagira ingaruka kubiciro bya pH nubushyuhe bwumuti.

6. Kubika amazi
HEMC ikoreshwa nkumukozi wo gufata amazi mubikorwa byubwubatsi. Kubika amazi meza birashobora kongera igihe cyo gufata amazi yibikoresho bishingiye kuri sima kandi bigateza imbere imikorere no guhuza amabuye ya minisiteri. Mugihe cyubwubatsi, HEMC irashobora kugabanya neza igihombo cyamazi kandi ikirinda ibibazo nko guturika no gutakaza imbaraga biterwa no gukama vuba kwa minisiteri. Byongeye kandi, mu marangi ashingiye ku mazi na wino, gufata amazi ya HEMC birashobora kandi gukomeza gutembera neza kw'irangi, kunoza imikorere yubwubatsi no gukora neza.

7. Biocompatibilité n'umutekano
Kuberako HEMC ikomoka kuri selile naturel, ifite biocompatibilité nziza nuburozi buke. Kubwibyo, yakoreshejwe cyane mubijyanye n'ubuvuzi no kwisiga. Irashobora gukoreshwa nkibintu bidahwitse cyangwa bikomeza kurekura ibinini byibiyobyabwenge kugirango bifashe kurekura neza ibiyobyabwenge mumubiri. Byongeye kandi, nkumukozi wibyimbye kandi ukora firime mumavuta yo kwisiga, HEMC irashobora gutanga ingaruka zitanga uruhu kuruhu, kandi umutekano wacyo mwiza ukaba ukoreshwa mugihe kirekire.

8. Imirima yo gusaba
Bitewe nimikorere myinshi ya hydroxyethyl methylcellulose, yakoreshejwe cyane mubice byinshi byinganda:

Inganda zubaka: Mubikoresho byubwubatsi nka sima ya sima, ifu yuzuye, nibicuruzwa bya gypsumu, HEMC irashobora gukoreshwa nkibintu byimbitse, bigumana amazi, hamwe nibifata neza kugirango imikorere yubwubatsi irangire neza.
Ipitingi na wino: HEMC ikoreshwa cyane mumarangi ashingiye kumazi hamwe na wino nkibyimbye hamwe na stabilisateur kugirango irusheho kuringaniza, gutuza, no kurabagirana kw irangi nyuma yo kumisha.
Urwego rwubuvuzi: Nkumuntu udatandukanya, wifata kandi urekura-kurekura mubatwara ibiyobyabwenge, birashobora kugena igipimo cyo kurekura ibiyobyabwenge mumubiri no kunoza bioavailable yibiyobyabwenge.
Amavuta yo kwisiga hamwe n’ibicuruzwa byita ku muntu: Mu bicuruzwa byita ku muntu ku giti cye nk'amavuta yo kwisiga, amavuta, amavuta, na shampo, HEMC irashobora gukoreshwa nk'ibyimbye kandi bitanga amazi, kandi ifite uruhu rwiza n'umusatsi.
Inganda zikora ibiribwa: Mu biribwa bimwe na bimwe, HEMC irashobora gukoreshwa nka stabilisateur, emulisiferi nogukora firime. Nubwo imikoreshereze y’ibiribwa igengwa n’ibihugu bimwe na bimwe, umutekano wacyo wamenyekanye cyane.

9. Guhungabanya ibidukikije no kwangirika
Nkibikoresho bishingiye kuri bio, HEMC irashobora kwangirika buhoro buhoro mubidukikije, kandi inzira yayo yo kwangirika ikorwa ahanini nigikorwa cya mikorobe. Kubwibyo, HEMC ifite umwanda muke kubidukikije nyuma yo kuyikoresha kandi ni imiti yangiza ibidukikije. Mubihe bisanzwe, HEMC irashobora kubora mumazi, dioxyde de carbone nizindi molekile ntoya, kandi ntizatera umwanda muremure mubutaka no mumazi.

Hydroxyethyl methylcellulose ningirakamaro cyane mumazi ashonga ya selile. Bitewe nimiterere yihariye yumubiri nubumashini nko kubyibuha cyane, kubika amazi, gutuza ubushyuhe hamwe na biocompatibilité, ikoreshwa cyane mubikorwa byinshi nkubwubatsi, ibifuniko, ubuvuzi, amavuta yo kwisiga, nibindi. ingirakamaro yimikorere yingenzi muri sisitemu zitandukanye. Cyane cyane murwego aho ari ngombwa kongera ibicuruzwa byijimye, kongera ubuzima bwa serivisi cyangwa kunoza imikorere, HEMC igira uruhare rudasubirwaho. Muri icyo gihe, nk'ibikoresho byangiza ibidukikije, HEMC yerekanye iterambere rirambye mu nganda kandi ifite isoko ryiza.
