Hydroxyethyl Cellulose (HEC) ni polymer idashonga mu mazi ikoreshwa cyane mu gusiga, amavuta yo kwisiga, ubuvuzi, ibiribwa, gukora impapuro, gucukura amavuta n'ibindi bikorwa by'inganda. Ni imvange ya ether ya cellulose iboneka binyuze mu gusya cellulose, aho hydroxyethyl isimbura igice cy'amatsinda ya hydroxyethyl ya cellulose. Imiterere ya hydroxyethyl cellulose ituma iba kimwe mu bintu by'ingenzi bigize thickeners, gelling agents, emulsifiers na stabilizers.
Aho hydroxyethyl cellulose ibira
Hydroxyethyl cellulose ni polymeri nini ya molekile ifite uburemere bunini bwa molekile, kandi aho ishyuha ntabwo byoroshye kumenya nk'aho ibyinjira mu bintu bito bya molekile bito bito bibyinjiramo. Mu buryo bufatika, ibikoresho byinshi bya molekile nka hydroxyethyl cellulose ntibigira aho bishyuha neza. Impamvu ni uko ibintu nk'ibyo bibora mu gihe cyo gushyuha, aho guhinduka mu buryo butaziguye kuva ku mazi kugera kuri gaze binyuze mu mpinduka nk'ibintu bisanzwe bya molekile. Kubwibyo, igitekerezo cy' "aho bishyuha" cya hydroxyethyl cellulose ntigikoreshwa.
Muri rusange, iyo hydroxyethyl cellulose ishyushye ku bushyuhe bwinshi, ibanza gushonga mu mazi cyangwa mu bintu biyungurura ibinyabuzima kugira ngo ikore umuti wa colloidal, hanyuma ku bushyuhe bwinshi, uruhererekane rwa polymer ruzatangira gucika no kubora mu buryo bw'ubushyuhe, rurekura molekile nto nka amazi, dioxyde de carbone n'ibindi bintu bihindagurika bidakoresheje uburyo busanzwe bwo kubira. Kubwibyo, hydroxyethyl cellulose ntabwo ifite aho ishyuha neza, ahubwo ifite ubushyuhe bwo kubora, buhinduka bitewe n'uburemere bwayo bwa molekile n'urwego rwo kuyisimbura. Muri rusange, ubushyuhe bwo kubora bwa hydroxyethyl cellulose ubusanzwe buri hejuru ya 200°C.
Gukomera k'ubushyuhe bwa hydroxyethyl cellulose
Selulosi ya Hydroxyethyl ifite ubushobozi bwo kudahinduka mu bushyuhe bw'icyumba, ishobora kwihanganira imiterere runaka ya aside na alkali, kandi ikagira ubushobozi bwo kurwanya ubushyuhe runaka. Ariko, iyo ubushyuhe buri hejuru cyane, cyane cyane iyo nta bintu bishongesha cyangwa ibindi bintu bitera imbaraga, imiyoboro ya polymer itangira gucika bitewe n'ubushyuhe. Iyi gahunda yo gushonga kw'ubushyuhe ntabwo iherekejwe no kubira kugaragara, ahubwo iherekezwa no gucika buhoro buhoro k'umuyoboro no kubura amazi, ikarekura ibintu bihindagurika kandi amaherezo ikavamo ibintu bya karuboni.
Mu nganda, kugira ngo hirindwe kubora guterwa n'ubushyuhe bwinshi, hydroxyethyl cellulose ntabwo ikunze guhura n'ibidukikije birengeje ubushyuhe bwayo bwo kubora. Ndetse no mu bushyuhe bwinshi (nk'ikoreshwa ry'amazi yo gucukura peteroli), hydroxyethyl cellulose ikunze gukoreshwa hamwe n'ibindi bikoresho kugira ngo yongere ubushyuhe bwayo buhamye.
Gukoresha hydroxyethyl cellulose
Nubwo hydroxyethyl cellulose idafite aho ishyuha neza, ubushobozi bwayo bwo gushonga no gukomera bituma ikoreshwa cyane mu nganda nyinshi. Urugero:
Inganda zikora irangi: hydroxyethyl cellulose ishobora gukoreshwa nk'inyunganizi mu gufasha guhindura imiterere y'irangi, gukumira imvura no kunoza uburyo irangi rihagaze n'uburyo rituje.
Ibikoresho byo kwisiga n'imiti ikoreshwa buri munsi: Ni ikintu cy'ingenzi mu masabune menshi, ibikoresho byo kwita ku ruhu, shampoos na toothpaste, bishobora guha ubwiza bukwiye, ubushyuhe n'ubudahangarwa.
Inganda z'imiti: Mu gutegura imiti, hydroxyethyl cellulose ikunze gukoreshwa mu gukora ibinini birekura burundu n'amabara yo gusiga kugira ngo hagenzurwe igipimo cyo kurekura imiti.
Inganda z'ibiribwa: Nk'umuti ukomeza ubushyuhe, utuma ibintu bikomera kandi bigatera imbaraga, hydroxyethyl cellulose ikoreshwa no mu biribwa, cyane cyane muri ice cream, jelly na sosi.
Gucukura amavuta: Mu gucukura ahantu hacukurwa amavuta, hydroxyethyl cellulose ni ingenzi mu gucukura amazi, bishobora kongera ubukana bw'amazi, bigatuza urukuta rw'iriba kandi bigagabanya igihombo.
Nk'ibikoresho bya polymer, hydroxyethyl cellulose ntabwo igira aho ishyuha neza kuko ibora iyo ubushyuhe bwinshi burenze ubwo isanzwe ishyuha. Ubushyuhe bwayo bwo kubora ubushyuhe busanzwe buri hejuru ya 200°C, bitewe n'uburemere bwayo bwa molekile n'urwego rwo kuyisimbura. Nyamara, hydroxyethyl cellulose ikoreshwa cyane mu gusiga, amavuta yo kwisiga, imiti, ibiryo na peteroli bitewe n'ubushobozi bwayo bwiza bwo gukurura, gusya, gusya no gutuza. Muri ubu buryo, akenshi yirindwa guhura n'ubushyuhe bwinshi cyane kugira ngo igire imikorere myiza kandi ihamye.
