Umphumela we-HEC ekunamatheni okumboza

I-Hydroxyethyl cellulose (HEC)iyi-polymer engeyona i-ionic encibilikayo emanzini. Isetshenziswa kabanzi embonini yokumboza ngenxa yokuncibilika kwayo okuhle kwamanzi, ukuqina, izakhiwo zokwakha ifilimu kanye nomsebenzi omuhle kakhulu womphezulu. Ekwakheni kokumboza, i-HEC ayigcini nje ngokuhlinzeka ngezakhiwo ezifanele ze-rheological, kodwa futhi idlala indima ebalulekile ekunamatheleni kokumboza.

1. Izici zesakhiwo se-HEC

Ama-molecule e-HEC akhiwe ngamaketanga e-cellulose kanye nama-substituent e-hydroxyethyl. I-cellulose chain yayo inesakhiwo se-polyhydroxy, esingakha ukusebenzisana okuqinile nobuso be-substrate yokumboza ngokusebenzisa ama-hydrogen bonds, ngaleyo ndlela kuthuthukiswe ukunamathela kwe-coating. Ngaphezu kwalokho, i-hydroxyethyl substituent ku-AnxinCel®HEC molecule yandisa ukuncibilika kwamanzi, okuvumela ukuthi ihlakazeke ngokulinganayo e-coating, ngaleyo ndlela kuthuthukiswe ikhwalithi yokwakha ifilimu ye-coating.

2. Indlela ye-HEC ekunamathiseleni okumboziwe

I-HEC ekumbozweni ithuthukisa kakhulu ukunamathela kokumbozwa ngezindlela ezilandelayo:

Ukumanziswa kwamanzi okuthuthukisiwe ebusweni

I-HEC inomsebenzi omuhle wobuso, onganciphisa ukucindezelwa kobuso bengubo futhi uthuthukise ukumanziswa kwengubo ebusweni bengubo. Lokhu kumanziswa kwenza ingubo ikwazi ukuxhumana eduze kobuso bengubo, inciphise izikhala esibonakalayo, ngaleyo ndlela ithuthukise ukunamathelana phakathi kwengubo nengubo.

Ukubopha kwe-hydrogen kuthuthukisa ukubopha kwe-interfacial

Amaqembu e-hydroxyl kuma-molecule e-HEC angakha izibopho ze-hydrogen namaqembu asebenzayo e-polar ebusweni be-substrate (njengokhuni, ingilazi, insimbi, njll.). Lo mphumela uthuthukisa ukubopha ngokomzimba phakathi kwengubo ne-substrate, okwenza ingubo ingabi namathuba amaningi okuqhekeka ngaphansi kwamandla angaphandle.

Umthethonqubo wempahla ye-Rheological

I-HEC inomthelela omkhulu wokulawula izakhiwo ze-rheological zesembozo, inciphisa ukugeleza kwayo ngokuqinisa isembozo futhi ivimbele ukugoba ngokweqile kwesembozo ebusweni be-substrate. Lesi sici sisiza isembozo sakhe ifilimu efanayo ebusweni be-substrate futhi sinciphise ukwehla kokunamathela okubangelwa ukujiya kwefilimu okungalingani.

Umphumela wokusiza ekwakheni ifilimu

I-HEC ingathuthukisa ikhwalithi yokwenza ifilimu yengubo ngesikhathi senqubo yokwenza ifilimu, iqinisekise ukuthi ingubo iyaqhubeka futhi iyafana ngemva kokoma. Lokhu kufana kunciphisa izindawo ezinephutha zengubo, ngaleyo ndlela kuthuthukise ukunamathela okuphelele.

3. Izibonelo zezicelo ze-HEC ezimbozweni ezahlukene

Izembozo zezakhiwo eziqhutshwa ngamanzi

Ezimbozweni zezakhiwo, i-HEC ithuthukisa ukunamathela kwezimbozo ezisekelweni zodonga (njengesimende noma i-gypsum) ngokuziqinisa, ukuthuthukisa ukumanzi, nokuthuthukisa amandla efilimu. Ngaphezu kwalokho, izakhiwo ze-HEC zokulwa nokugoba zinegalelo ekubushelelekeni kobuso bembozo ngemva kokusetshenziswa.

Ukumbozwa ngokhuni

Ngezimbozo zokhuni, umphumela wokubopha i-hydrogen we-HEC ubonakala kakhulu. Ubuso bokhuni bucebile ngamaqembu e-hydroxyl, futhi i-HEC ingakha isibopho esiqinile nayo, okuthuthukisa kakhulu ukuqina nokunamathela kwengubo.

Izembozo zensimbi

Ezimbozweni zensimbi, ukuthuthukiswa kokumanzi kwe-HEC kwenza ukuthi ingubo ikwazi ukumboza kangcono ubuso bensimbi futhi ithuthukise ukunamathela kwengubo nge-polarity. Lokhu kubaluleke kakhulu ezimbozweni ezilwa nokugqwala.

Izembozo zengilazi

I-HEC inomphumela omuhle wokukhuthaza ukunamathela ezindaweni ezibushelelezi ezingezona eziphansi njengengilazi, futhi izici eziphansi zamaqembu e-hydroxyl kuma-molecule ayo zingenza kube nzima ukuhambisana kwamakhemikhali phakathi kobuso bengilazi kanye nokwembozwa.

4. Ukulinganiselwa kwe-HEC ekunamatheleni kokumboza

NakubaI-HECinezinzuzo ezibalulekile ekuthuthukiseni ukunamathela kokumboza, futhi inemikhawulo ethile. Isibonelo, i-HEC kulula ukuyimunca umswakama endaweni enomswakama ophezulu, okungaholela ekunciphiseni ukusebenza kokumboza. Ngaphezu kwalokho, kwezinye izembozo zezimboni ezifunwa kakhulu, i-HEC idinga ukusetshenziswa kanye nezinye izithasiselo ukuze kufezwe ukusebenza okuphezulu.

Njengesithako esibalulekile sokuqinisa nokwakha ifilimu, ukusetshenziswa kwe-AnxinCel®HEC ezimbozweni kuthuthukisa kakhulu ukunamathela kwezimbozo. Kwenza ukuthi izimbozo zikwazi ukuzivumelanisa kangcono nezinhlobo ezahlukene zezingqimba ngokusebenzisa izindlela eziningi ezifana nokuthuthukisa ukumanzi, ukwakha izibopho ze-hydrogen, kanye nokuthuthukisa izakhiwo zokwakha ifilimu. Kodwa-ke, ekusetshenzisweni kwangempela, inani lokwengeza kanye nokuhambisana kwe-HEC kufanele kulungiselelwe ngokuhambisana nefomula ethile yokumboza kanye nendawo yokusetshenziswa ukuze kudlale indima yayo ngokugcwele.
