Thickener hec hydroxyethyl selulose

Hydroxyethyl selulose (HEC) ni inkomoko ya selilose idasanzwe ikoreshwa cyane mu nganda zinyuranye kubera kubyimbye kwiza, guhagarika, no kwigana. HEC ni polymer yamashanyarazi ishobora gushonga byoroshye mumazi akonje kugirango bibe ibisubizo bisobanutse kandi bitagira ibara. HEC isanzwe ikoreshwa nkibyimbye muburyo butandukanye bwo gusaba, harimo ibifuniko, ibifatika, ibicuruzwa byita ku muntu, hamwe n’imiti.

HEC ikorwa muguhindura selile karemano, polymer igizwe nibice bya glucose bihujwe hamwe na β (1 → 4) glycosidic. Guhindura selile birimo kwinjiza hydroxyethyl matsinda (-CH2CH2OH) kuri anhydroglucose yibice byumugongo wa selile. Iri hinduka ritanga polymer-ere-e-polymer ishobora gukora hydrogène ihuza na molekile zamazi, bigatuma habaho igisubizo kiboneye.

HEC niyongera cyane bitewe nubushobozi bwayo bwo gukora imiterere isa na gel iyo yongewe kumuti. Amatsinda ya hydroxyethyl kuri molekile ya HEC arashobora gukorana na molekile zamazi, bikavamo gushiraho imigozi ya hydrogen. Hydrogene ihuza molekile ya HEC na molekile y'amazi itera molekile ya HEC guhinduka kandi ikaguka mubunini. Mugihe molekile ya HEC yagutse, ikora imiterere-yimiyoboro itatu-imitego ifata amazi nibindi bice byashonze, bigatuma ubwiyongere bwibisubizo byumuti.

Ubushobozi bwo kubyimba bwa HEC bugira ingaruka kubintu bitandukanye, harimo kwibanda kwa HEC mugisubizo, ubushyuhe, na pH. Ubwinshi bwa HEC mubisubizo biganisha ku kwiyongera gukabije kwijimye. Ariko, kongera ubukana bwa HEC kurenza ingingo runaka birashobora gutuma igabanuka ryijimye bitewe no gushinga hamwe. Ubushyuhe nabwo bugira ingaruka ku bushyuhe bwa HEC, hamwe nubushyuhe bwo hejuru butera kugabanuka kwijimye. PH yumuti irashobora kandi kugira ingaruka kububasha bwa HEC, hamwe nagaciro ka pH hejuru biganisha kugabanuka kwijimye.

HEC isanzwe ikoreshwa nkibyimbye mubikorwa bitandukanye, harimo ibishishwa hamwe. Mu gutwikira, HEC yongewe kumikorere kugirango itezimbere imiterere ya rheologiya. Imiterere ya rheologiya yerekana igifuniko yerekeza kubushobozi bwayo bwo gutembera no kurwego hejuru. HEC irashobora kunoza imigezi no kuringaniza igifuniko cyongera ububobere bwayo no kugabanya kugabanuka kwayo. HEC irashobora kandi kunoza ituze rya coating mukurinda gutuza pigment nibindi bikomeye.

Mubifatika, HEC ikoreshwa nkibyimbye kugirango irusheho kwiyegereza no gukomera kwifata. Ubukonje bwa afashe ni ngombwa kubushobozi bwayo bwo kwizirika ku buso no kuguma mu mwanya. HEC irashobora kunoza ubwiza bwibiti kandi ikabuza gutonyanga cyangwa gukora. HEC irashobora kandi kunoza ubuhanga bwo gufatira hamwe, ikayemerera gukomera neza hejuru.

Mu bicuruzwa byita ku muntu ku giti cye, HEC ikoreshwa nkibyimbye na stabilisateur. HEC ikunze gukoreshwa muri shampo, kondereti, no koza umubiri kugirango bongere ubwiza bwabo nuburyo bwiza. HEC irashobora kandi kunoza ituze ryibicuruzwa birinda gutandukanya ibyiciro no gutuza ibinini.

Muri farumasi, HEC ikoreshwa nkumubyimba kandi uhagarika. HEC ikoreshwa muburyo bwo guhagarika umunwa kugirango ihagarike imiti idashonga muburyo bwamazi. HEC irashobora kandi gukoreshwa nkibyimbye mumavuta ya cream hamwe na geles kugirango bitezimbere ubwiza bwabyo.

Mu gusoza, HEC ni polymer-eruber polymer ikoreshwa cyane nkibyimbye mu nganda zinyuranye bitewe nubwiza bwayo buhebuje, guhagarika, no kwigana.
