Hydroxyethylcellulose (HEC) ni polimeri ikabura amazi ikoreshwa cyane mubicuruzwa bitandukanye byinganda ninganda za buri munsi, cyane cyane mubicuruzwa byita kumuntu no kumesa. Ifite umubyimba mwiza, guhagarika, kwigana, gukora firime no gukingira colloid imikorere, kuburyo ikoreshwa kenshi mubyimbye mumasabune yamazi.
1. Imiterere nimiterere ya hydroxyethyl selulose
HEC ni inkomoko idakomoka kuri selile ikoresheje reaction ya etherification kandi ifite ubushobozi bwo kuyobora hamwe na hydrophilicity. Urunigi rwa molekile ya HEC rugizwe nitsinda ryinshi rya hydroxyethyl risimbuza hydrogène atome ya hydrogène ya selile isanzwe, ikora urukurikirane rwimikorere miremire miremire. Iyi molekulire ituma HEC yabyimba vuba mumazi kugirango ikore igisubizo kimwe.
Umutungo wingenzi wa HEC nuguhuza nindangagaciro zitandukanye za pH. Ikomeza imbaraga zayo hejuru yubunini bwa pH, ikayiha inyungu yibicuruzwa nkibisabune byamazi, bishobora kuba bifite ibintu byinshi bikora hamwe nimpinduka za pH. Byongeye kandi, HEC ifite kandi biocompatibilité nziza n'umutekano, kandi ikwiriye gukoreshwa mubicuruzwa bitandukanye bihura numubiri wumuntu, nkisabune yamazi, shampoo, nibindi.
2. Uburyo bwo kubyimba hydroxyethyl selulose mu isabune y'amazi
Mu isabune y'amazi, uburyo nyamukuru bwibikorwa bya HEC nkibyimbye ni ukongera ububobere bwisabune yamazi ushonga mumazi kugirango bibe igisubizo kiboneye. By'umwihariko, iyo HEC yashongeshejwe mumazi, iminyururu yayo ya molekile ihuza na molekile zamazi binyuze mumigozi ya hydrogène ya intermolecular kugirango ibe imiterere y'urusobekerane. Uru rusobe rushobora guhuza neza umubare munini wamazi ya molekile, bityo bikongerera cyane ubwiza bwumuti.
Ingaruka yibyibushye ya HEC ifitanye isano rya bugufi nuburemere bwa molekile hamwe ninyongera. Muri rusange, uko uburemere bwa molekuline bwa HEC, niko ubwiza bwibisubizo byakozwe; icyarimwe, urwego rwo hejuru rwa HEC mugisubizo, niko bigaragara ingaruka zo kubyimba zizaba. Ariko, mubikorwa bifatika, kwibanda cyane kwa HEC birashobora gutuma igisubizo kiboneka cyane kandi bikagira ingaruka kubukoresha, bityo rero bigomba kugenzurwa neza mugihe cyo gutegura.
3. Ibyiza byingaruka za HEC
HEC ifite ibyiza byinshi kurenza izindi. Mbere ya byose, ifite amazi meza cyane kandi irashobora gushonga vuba mumazi akonje cyangwa ashyushye kandi igakora igisubizo kimwe. Icya kabiri, HEC ntabwo yibyibushye gusa murwego rwo hasi, ahubwo inatanga ingaruka zihamye zo kubyimba, zifite akamaro kanini mubicuruzwa byisabune byamazi bisaba kubika igihe kirekire. Icya gatatu, nkikibyimbye kitari ionic, HEC irashobora kugumana ubukonje butajegajega mubihe bitandukanye bya pH kandi ntabwo byangizwa nibindi bice bigize sisitemu.
4. Imyitozo yo gusaba HEC mugutegura isabune y'amazi
Mu musaruro nyirizina, ubusanzwe HEC yongewe kumasabune y'amazi muburyo bwa poro. Kugirango harebwe niba HEC ishobora gushonga burundu kandi ikagira ingaruka zibyibushye, mubisanzwe birakenewe kwitondera uburinganire bwo kuvanga mugihe wongeyeho HEC kugirango wirinde guhuriza hamwe. Mubyongeyeho, kugirango turusheho kunoza imikorere yisabune yamazi, HEC ikoreshwa kenshi ifatanije nubundi bubyibushye, humectants cyangwa surfactants kugirango igere kubicuruzwa byiza hamwe nuburambe bwabakoresha.
Nukubyimba neza, hydroxyethyl selulose ifite amahirwe menshi yo gukoresha mumasabune yamazi. Irashobora kongera cyane ubwiza bwibicuruzwa no kunoza uburambe bwabakoresha. Ifite kandi guhuza neza no gutuza kandi ni amahitamo meza yo kubyimba isabune y'amazi.
