Hydroxyethyl selulose (HEC) ni selile yingenzi ya elegitoronike ya selile, ikoreshwa cyane mugutwikira, gucukura amavuta, imiti nizindi nzego. Ikibanza cyayo cyo gushonga nikintu cyingenzi kigira ingaruka kumikorere no kugikoresha. Ibintu bigira ingaruka kumashanyarazi ya hydroxyethyl selulose irashobora kugabanywamo ibice byinshi, nkimiterere ya molekile, urwego rwo gusimbuza, uburemere bwa molekile, kristu, imyanda, nibidukikije.
1. Imiterere ya molekile
Hydroxyethyl selulose nigicuruzwa cya selile nyuma ya ethoxylation. Imiterere yibanze ni uko atome ya hydrogen muri molekile ya selile isimburwa nitsinda rya hydroxyethyl. Umwanya, umubare na gahunda yo gusimbuza hydroxyethyl bizagira ingaruka kumwanya wacyo.
Umwanya wo gusimbuza: Buri glucose igizwe na selile ifite amatsinda atatu ya hydroxyl ashobora gusimburwa. Gusimbuza imyanya itandukanye bizahindura imiterere yimiterere ya molekile, bityo bigire ingaruka kumashanyarazi.
Umubare wabasimbuye: Ubwiyongere bwumubare wabasimbuye muri rusange bigabanya guhuza hydrogene ihuza molekile, bityo bikagabanya aho gushonga.
Itondekanya rya gahunda yo gusimbuza: Ikwirakwizwa risanzwe kandi risimburwa buri gihe bigira ingaruka zitandukanye kumihindagurikire no guhuza urunigi rwa molekile, bityo bikagira ingaruka kumashanyarazi.
2. Impamyabumenyi yo gusimburana (DS)
DS bivuga impuzandengo ya hydroxyethyl insimburangingo kuri buri glucose. Urwego rwo gusimbuza rufite ingaruka zikomeye ku gushonga, bigaragarira cyane cyane mu bice bikurikira:
DS yo hasi: Kuri DS yo hasi, hydrogène ihuza molekile ya hydroxyethyl selulose irakomeye, bigatuma molekile zifatana cyane kandi aho gushonga hejuru.
DS yo hejuru: DS yo hejuru yongerera imiterere ya molekile kandi igabanya ingaruka zo guhuza hydrogène, bigatuma molekile yoroshye kunyerera kandi aho gushonga bikamanuka.
3. Uburemere bwa molekile
Uburemere bwa molekuline bugira ingaruka itaziguye kumashanyarazi ya hydroxyethyl selile. Muri rusange, uko uburemere bwa molekile nini, niko urunigi rurerure, niko imbaraga za der der Waals zikomeye hagati ya molekile, kandi niko hejuru yo gushonga. Mubyongeyeho, ubugari bwikwirakwizwa rya molekuline nabyo bizagira ingaruka ku gushonga, kandi gukwirakwiza kwinshi bishobora kuganisha ku ngingo zidashonga.
Uburemere buke bwa molekile: Iminyururu ya molekile ni ndende, ihujwe cyane, kandi aho gushonga ni muremure.
Uburemere buke bwa molekile: Iminyururu ya molekile ni ngufi, imbaraga za intermolecular zidakomeye, kandi aho gushonga ni muke.
4. Crystallinity
Hydroxyethyl selulose ni polymer amorphous, ariko irashobora kuba ifite uduce tumwe na tumwe twa kristu. Kuba hari uturere twa kristaline byongera aho gushonga kuko imiterere ya kristaline ihagaze neza kandi bisaba imbaraga nyinshi zo kumena izo nyubako zateganijwe. Urwego rwa hydroxyethylation hamwe nuburyo ibintu bigira ingaruka kuri kristu.
Ikirahure kinini: imiterere iremereye, ingingo yo hejuru yo gushonga.
Ubukonje buke: imiterere irekuye, ingingo yo gushonga.
5. Umwanda
Mugihe cyo gukora hydroxyethyl selulose, bimwe mubikoresho fatizo bidakorewe, catalizator cyangwa nibindi bicuruzwa bishobora kuguma. Kubaho kw'imyanda irashobora guhindura imbaraga za intermolecular, bityo bikagira ingaruka kumashanyarazi. Urugero:
Igisigisigi gisigaye: ibigo birashobora gushingwa, bigahindura aho bishonga.
Ibicuruzwa: Kuba hari ibicuruzwa bitandukanye bizahindura imikoranire ya sisitemu kandi bigira ingaruka kumashanyarazi.
6. Ibidukikije
Ibidukikije nkubushyuhe nubushuhe nabyo bizagira ingaruka kumashanyarazi ya hydroxyethyl selulose. Mugihe cy'ubushyuhe bwinshi, hydroxyethyl selulose izajya ikora plastike nyuma yo gufata amazi, bizagabanya imbaraga za intermolecular kandi bigabanye gushonga.
Ubushyuhe bwo hejuru: Irashobora gutera ubushyuhe bwumuriro wibikoresho no kwagura aho gushonga.
Ubushuhe bwinshi: Urunigi rwa molekile iroroshye guhinduka nyuma yo gufata amazi, kandi aho gushonga bigabanuka.
7. Ikoranabuhanga
Ubushyuhe, imbaraga zogosha, ibihe byumye, nibindi mugihe cyo gutunganya bizagira ingaruka kumashanyarazi yibicuruzwa byanyuma. Uburyo butandukanye bwo gutunganya bizaganisha kuri molekuliyeri zitandukanye hamwe na kristu, ibyo nabyo bigira ingaruka kumashanyarazi.
Ubushyuhe bwo gutunganya: Ubushyuhe bwo hejuru burashobora gutera kwangirika igice cyangwa guhuza, guhindura aho gushonga.
Uburyo bwo kumisha: Kuma vuba no gukama buhoro bigira ingaruka zitandukanye kumitunganyirize ya molekile, kandi aho gushonga nabyo bizaba bitandukanye.
Muri make, ibintu bigira ingaruka kumashanyarazi ya hydroxyethyl selulose harimo imiterere ya molekile, urwego rwo gusimbuza, uburemere bwa molekile, kristu, umwanda, ibidukikije hamwe nubuhanga bwo gutunganya. Kubikorwa bifatika no gutunganya, kugenzura neza ibyo bintu birashobora guhindura imikorere ya hydroxyethyl selulose kandi bigatuma byuzuza ibisabwa bitandukanye. Mubikorwa byo kubyaza umusaruro, guhindura siyanse mubipimo ntibishobora kugenzura gusa gushonga kwibicuruzwa, ariko kandi binatezimbere ihame nubuziranenge bwibicuruzwa.
