Hydroxyethyl selulose (HEC) ni polymer idafite ionic, amazi-elegitoronike ikomoka kuri selile. Ikoreshwa cyane mu nganda zitandukanye, zirimo ibifatika, aho ikora nk'umubyimba, uhindura imvugo, na stabilisateur. Ubushobozi bwa HEC bwo kongera ubwiza bwibintu bifatika nibyingenzi mubikorwa byinshi, byemeza neza, imikorere, no kuramba kwibicuruzwa bifata.
Ibyiza bya Hydroxyethyl Cellulose
HEC ikorwa no gukora selile hamwe na okiside ya Ethylene mubihe bya alkaline, bikavamo polymer hamwe nitsinda rya hydroxyethyl ifatanye numugongo wa selile. Urwego rwo gusimbuza (DS) no gusimbuza umubyimba (MS) nibintu byingenzi bigira ingaruka kumiterere ya HEC. DS bivuga impuzandengo ya matsinda ya hydroxyl kuri molekile ya selile yasimbujwe amatsinda ya hydroxyethyl, mugihe MS yerekana impuzandengo ya mole ya oxyde ya Ethylene yakiriye hamwe na mole imwe ya anhydroglucose muri selile.
HEC irangwa no gukomera kwayo mumazi, ikora ibisubizo bisobanutse kandi bisobanutse hamwe nubwiza bwinshi. Ubukonje bwabwo buterwa nimpamvu nyinshi, zirimo uburemere bwa molekile, kwibanda, ubushyuhe, na pH yumuti. Uburemere bwa molekuline ya HEC burashobora kuva hasi kugeza hejuru cyane, bigatuma habaho gukora ibifatika hamwe nibisabwa bitandukanye.
Uburyo bwo Kuzamura Viscosity
Kuvomera no kubyimba:
HEC yongerera ububobere bufatika cyane cyane mubushobozi bwayo bwo kuyobora no kubyimba mumazi. Iyo HEC yongewe kumazi yo mumazi, amatsinda ya hydroxyethyl akurura molekile zamazi, biganisha kubyimba iminyururu ya polymer. Uku kubyimba byongera igisubizo cyo guhangana nigitemba, bityo bikongera ububobere bwacyo. Ingano yo kubyimba hamwe nubwiza bwayo bivamo biterwa na polymer yibanze hamwe nuburemere bwa molekile ya HEC.
Ingirabuzimafatizo:
Mugukemura, polymers ya HEC ihura nikibazo kubera imiterere-ndende. Uku kwizirika kurema urusobe rubangamira urujya n'uruza rwa molekile muri afashe, bityo bikongera ububobere. Uburemere buke bwa molekuline HEC itera kwibumbira hamwe no kwiyegereza cyane. Urwego rwo kwizirika rushobora kugenzurwa muguhindura polymer hamwe nuburemere bwa molekile ya HEC yakoreshejwe.
Guhuza Hydrogen:
HEC irashobora gukora imigozi ya hydrogène hamwe na molekile zamazi nibindi bice muburyo bwo gufatira hamwe. Ihuriro rya hydrogène ritanga umusemburo mugukora urusobe rwubatswe mubisubizo. Amatsinda ya hydroxyethyl kumugongo wa selile yongera ubushobozi bwo gukora imigozi ya hydrogène, bikarushaho kwiyongera.
Imyitwarire Yogosha:
HEC yerekana imyitwarire-yogosha, bivuze ko ububobere bwayo bugabanuka mugihe cyo guhangayika. Uyu mutungo ufite akamaro mubikorwa bifata kuko bituma ushyira mugikorwa cyogosha (nko gukwirakwiza cyangwa gukaraba) mugihe ukomeza kwiyegereza cyane mugihe uruhutse, byemeza imikorere myiza kandi ihamye. Imyitwarire yogosha ya HEC iterwa no guhuza iminyururu ya polymer mu cyerekezo cyingufu zikoreshwa, kugabanya kurwanya imbere byigihe gito.
Porogaramu muburyo bwo gufatira hamwe
Ibikoresho bifata amazi:
HEC ikoreshwa cyane mumazi ashingiye kumazi, nk'ay'impapuro, imyenda, n'ibiti. Ubushobozi bwayo bwo kubyimba no guhagarika ifumbire mvaruganda yemeza ko ikomeza kuvangwa kimwe kandi byoroshye kuyikoresha. Mu mpapuro no gupakira ibintu, HEC itanga ubukonje bukenewe kugirango ikoreshwe neza kandi ihuze imbaraga.
Ibikoresho byubaka:
Mu byuma byubaka, nkibikoreshwa mugushiraho amabati cyangwa gutwikira urukuta, HEC yongerera ubwiza, igateza imbere imikorere yomuti hamwe no kurwanya sag. Igikorwa cyo kubyimba cya HEC cyemeza ko ibifatika bigumaho mugihe cyo gusaba kandi bigashyirwaho neza, bitanga umurongo ukomeye kandi urambye.
Amavuta yo kwisiga no kwita kumuntu:
HEC ikoreshwa kandi mubikoresho byo kwisiga no kwita kubantu bakeneye ibintu bifata neza, nko mumisatsi yimisatsi hamwe na masike yo mumaso. Muri iyi porogaramu, HEC itanga uburyo bworoshye kandi bumwe, kuzamura imikorere yibicuruzwa hamwe nuburambe bwabakoresha.
Ibikoresho bifata imiti:
Mu nganda zimiti, HEC ikoreshwa muburyo bwa transdermal hamwe nubundi buryo bwo gutanga imiti aho ibicucu bigenzurwa ningirakamaro kugirango imikorere yifashe. HEC iremeza ko igipande gifata kimwe, gitanga imiti ihoraho kandi igahuza uruhu.
Ibintu bigira ingaruka kumyororokere
Kwibanda:
Ubwinshi bwa HEC muburyo bwo gufatira hamwe burahuye neza nubwiza. Ubushuhe bwinshi bwa HEC butera kwiyongera kwijimye kubera imikoranire ikomeye ya polymer hamwe no gufatana. Nyamara, kwibanda cyane kurenza urugero birashobora kugushikana no kugorana.
Uburemere bwa molekile:
Uburemere bwa molekuline ya HEC ni ikintu gikomeye mu kumenya ububobere bwa afashe. Uburemere buke bwa molekuline HEC itanga ubukonje bwinshi kurwego rwo hasi ugereranije nuburemere buke bwa molekile. Guhitamo uburemere bwa molekuline biterwa nubushake bwifuzwa hamwe nibisabwa.
Ubushyuhe:
Ubushyuhe bugira ingaruka ku bwiza bwibisubizo bya HEC. Mugihe ubushyuhe bwiyongera, ubusanzwe ubukonje buragabanuka bitewe no kugabanuka kwa hydrogène no kwiyongera kwa molekile. Gusobanukirwa ubushyuhe-viscosity isano ningirakamaro kubisabwa guhura nubushyuhe butandukanye.
pH:
PH yo gufatira hamwe irashobora kugira ingaruka kuri HEC. HEC ihamye hejuru ya pH yagutse, ariko imiterere ya pH ikabije irashobora gutuma habaho impinduka mumiterere ya polymer hamwe nubwiza. Gutegura ibifatika muburyo bwiza bwa pH byerekana imikorere ihamye.
Ibyiza byo gukoresha Hydroxyethyl Cellulose
Kamere itari Ionic:
Imiterere itari ionic ya HEC ituma ishobora guhuzwa nibindi bice byinshi bigize formulaire, harimo izindi polymers, surfactants, na electrolytite. Uku guhuza kwemerera guhuza ibintu byinshi.
Ibinyabuzima bigabanuka:
HEC ikomoka kuri selile, umutungo kamere kandi ushobora kuvugururwa. Nibishobora kwangirika, bigatuma ihitamo ibidukikije kubidukikije. Imikoreshereze yacyo ijyanye no kwiyongera kubicuruzwa birambye kandi bitangiza ibidukikije.
Igihagararo:
HEC itanga ituze ryiza kubikorwa bifatika, irinda gutandukanya icyiciro no gutuza ibice bikomeye. Uku gushikama kwemeza ko ibifatika bikomeza kuba byiza mugihe cyubuzima bwacyo no mugihe cyo kubishyira mu bikorwa.
Ibiranga firime:
HEC ikora firime yoroheje kandi ibonerana iyo yumutse, ifitiye akamaro porogaramu isaba umurongo usobanutse kandi woroshye. Uyu mutungo ni ingirakamaro cyane mubisabwa nka labels na kaseti.
Hydroxyethyl selulose igira uruhare runini mukuzamura ubwiza bwamavuta yifashishije uburyo nka hydrata no kubyimba, kwangirika kwa molekile, guhuza hydrogène, hamwe nimyitwarire yo kunanura. Imiterere yacyo, harimo kwikemurira ibibazo, imiterere itari iyoni, ibinyabuzima bishobora kubaho, hamwe nubushobozi bwo gukora firime, bituma ihitamo neza kubikorwa bitandukanye bifatika. Gusobanukirwa nibintu bigira ingaruka kumyororokere ya HEC, nko kwibanda, uburemere bwa molekile, ubushyuhe, na pH, bituma abayikora bashushanya ibicuruzwa bifata neza kugirango babashe gukora neza. Mugihe inganda zikomeje gushakisha ibikoresho birambye kandi bikora neza, HEC ikomeje kuba ingirakamaro mugutegura ibicuruzwa bifata neza.
