Hydroxyethyl cellulose (HEC)ni polymeri idashonga mu mazi ikozwe muri cellulose karemano binyuze mu gushonga. Kubera ko ikora umuti wa colloidal ubonerana kandi uhamye iyo ushongeshejwe mu mazi, ikoreshwa cyane mu gusiga, imiti yo mu rugo, ibikoresho by'ubwubatsi, gucukura peteroli, n'ibindi bikorwa. Ingaruka za HEC ku bucucike bw'umubiri ni imwe mu nshingano zayo z'ingenzi, kandi iyi ngaruka ikubiyemo ibintu byinshi, harimo imiterere ya molekile, gushonga, n'imimerere yo hanze.
1. Isano iri hagati y'imiterere ya molekile n'ubucucike
Uruhererekane rw'ingenzi rwa HEC ni urutirigongo rwa selulosi ruhujwe n'imigozi ya β-1,4-glucose, aho amatsinda ya hydroxyl ari ku bipimo bya glucose asimburwa n'amatsinda ya hydroxyethyl. Igipimo cyo gusimbuza (DS) n'igipimo cyo gusimbuza molar (MS) bigena uburyo molekile ishonga mu mazi n'uburyo ibice by'uruhererekane bihinduka. Imigozi miremire ya molekile (uburemere bwinshi bwa molekile) n'igipimo kiringaniye cyo gusimbuza bitera kwivanga cyane nyuma yo gutoha, byongera cyane ubukana bw'imikorere y'umubiri. HEC ifite uburemere bwinshi bwa molekile itanga ubukana bwinshi cyane kuruta ubwoko bufite uburemere buke bwa molekile ku gipimo kimwe.
2. Uburyo bwo gushonga no gukurura amazi mu mubiri bigira ingaruka ku bucucike bw'umubiri
Uburyo bwo gushonga kwa HEC mu mazi bugizwe n'ibice bitatu: gutosesha, gukwirakwira, no gushonga. Iyo ifu ya HEC ihuye n'amazi, urwego rwo hanze ruhita rufata amazi maze rukaguka rugakora agahu, hagakurikiraho gushonga buhoro buhoro kw'urwego rw'imbere. Nyuma yo gushonga burundu, molekile z'uruhererekane rurerure zikwirakwira mu mazi ku buryo bungana, zigakora umuti ufite imiterere y'urusobe rw'amazi ibuza urujya n'uruza rw'amazi, bityo bikazamura ubukana bw'umuti. Iyo gushonga kutuzuye cyangwa habayeho kwivanga, imiyoboro ya molekile ntirapfunduka neza, bigatuma ubukana buke.
3. Isano iri hagati yo kwibanda ku kintu kimwe no kugorana kwacyo
Mu rugero ruto rw'ibipimo, ubushyuhe bwa HEC buriyongera hafi ku murongo uko ubushyuhe bwiyongera. Iyo ubushyuhe bugeze ku rugero rw'ibipimo by'ingenzi, ibipimo byinshi biba hagati y'iminyururu ya molekile, kandi ubushyuhe bwiyongera cyane. Ubushyuhe bwinshi bushobora gutuma umuti ugaragara nk'uwa gel, bigagabanya cyane ubushyuhe. Kubwibyo, mu mikoreshereze ifatika, ingano ikwiye igomba gutoranywa hashingiwe ku bisabwa na sisitemu kugira ngo ubushyuhe bugere ku ntego.
4. Ingaruka z'imiterere y'inyuma ku bucucike
Ubushyuhe: Ubwinshi bw'ibisubizo bya HEC bugabanuka uko ubushyuhe bwiyongera. Ibi biterwa nuko ubushyuhe bwinshi butuma ubushyuhe bw'iminyururu ya molekile burushaho kwiyongera, bigagabanya ubushyuhe bw'urwego rw'amazi. pH: Ubwinshi bw'ibisubizo bya HEC buhagaze neza mu rugero rwa pH ruri hagati ya 2-12, ariko imiterere ikabije ya aside na alkaline ishobora guhungabanya iminyururu ya molekile, bigatuma ubushyuhe bugabanuka.
Umunyu n'ibintu bishongesha: Nk'umubumbe utari uwoni, HEC irahindagurika iyo hari electrolytes nyinshi. Ariko, ubwinshi bw'umunyu cyangwa ibintu bishongesha by'umwimerere bishobora kugira ingaruka ku mazi, bityo bikagabanya ubukana bw'amazi.
5. Kugenzura ubukana bw'imitsi mu buryo butandukanye
Inganda zikora irangi: HEC itanga ubushobozi bwo gushyira mu gaciro no kugabanya irangi rya latex, bigatuma irangi ritamera neza.
Imiti yo mu rugo: Muri shampoo na sabune y'intoki, HEC itanga ubuziranenge butangaje kandi igatuma ifuro rituza.
Ibikoresho by'ubwubatsi: Muri sima, HEC itanga amazi ahagije kandi agakomeza gukoreshwa, bigatuma ikoreshwa ryayo rirushaho kuba ryiza.
Gucukura amavuta: HEC ikoreshwa mu gucukura kugira ngo ihindure rheology no kongera ubushobozi bwo gutwara chips.
Hydroxyethyl cellulose yongera cyane ubukana bw'uturemangingo binyuze mu kumena, gufungana, no gushingwa k'urusobe rw'uturemangingo tw'umuyoboro muremure mu mazi. Ubukana ntibufitanye isano gusa n'uburemere bwa HEC, urwego rwo gusimbuza, n'ubwinshi bwayo, ahubwo bunagira ingaruka ku bushyuhe, pH, n'imiterere y'uturemangingo. Mu gushushanya ibigize,guhitamo neza ubwoko bwa HECn'ingano y'ibipimo bitanga uburyo bwo kugenzura neza imiterere y'imiti ikoreshwa mu gufungana kw'amaraso, bigatuma habaho ingaruka zitandukanye kuva ku nto kugeza ku nini.
