Yini isicelo se-hydroxyethyl celtulose (HEC) ku-ink?

1. Sibutsetelo se-hydroxyethyl celtulose (HEC)

IHydroxYethyl Cellulose (I-HEC) iyi-nonic, i-polymer esolule emanzini ethathwe ku-cellulose. Kuyaziwa ngokuqina kwayo, kwakha amafilimu, nokuzinza, ukwenze kube isengezo esiguquguqukayo emikhakheni ehlukahlukene, kufaka phakathi ama-Pharmaceuticals, izimonyo, ukwakhiwa kanye nama-inks. Embonini ye-INK, i-HEC isebenzisa imisebenzi eminingi ebalulekile ethuthukisa ukusebenza nekhwalithi yokwakheka kwe-ink.

2 Indima ye-HEC ekwakhekeni kwe-ink

2.1 Rheology Ukuguqulwa
Enye yezicelo eziyisisekelo ze-HEC ku-Inks zinjenge-Rheology modifier. I-Rheology iphathelene nezici zokugeleza nezimo ze-defformation of thenki, ezibaluleke kakhulu ngezicelo ezinjengokuphrinta, ukunamathela, nokubhala. I-HEC ithonya i-viscosity nokuziphatha okugelezayo kwama-inks, okunikeza izinzuzo eziningana:

Ukulawulwa kwe-Viscosity: I-HEC ingaguqula i-viscosity yokwakhiwa kwe-ink ukufeza ukuvumelana okudingayo. Lokhu kubalulekile ezinhlotsheni ezahlukahlukene ze-inks, ezinjengelezo ezisetshenziswa ekuphrintweni kwesikrini, ukuphrinta okuguquguqukayo, lapho kubhalwa khona amaphrofayili athile wokuvuselela, lapho kudingeka khona amaphrofayili athile okubona ukuze asebenze kahle.
Ukuziphatha okugelezayo: Ngokushintsha izakhiwo ze-mboyamological, i-HEC isiza ukulawula ukusebenza kwe-Ink's shear ukunciphisa amandla, ukuqinisekisa ukuhamba okubushelelezi ngaphansi kwezimo ezihlukile ze-shear. Lokhu kubaluleke kakhulu kwizicelo ezinjengokuphrinta kwe-inkjet, lapho uyinki kufanele ugeleze ngokungaguquguquki ngokusebenzisa ama-nozzles amahle ngaphandle kokuvalwa.

2.2 Ukuqina nokumiswa
I-HEC isebenza njenge-stabilizer kanye ne-ejenti elisamiswayo ekusungulweni kwe-inki. Lo msebenzi ubalulekile ngokugcina i-homogeneity of inks, ukuvikela ukulungisa, kanye nokuqinisekisa ukusebenza okungaguquki:

Ukumiswa kwemigqa ye-pigment: E-Inks elinemibala, i-HEC isiza ukugcina imibala ihlakazeke ngokufana kulo lonke elakhiwa, ivimbela ukuqunjelwa. Lokhu kuphumela ekuguquguqukeni kombala okungcono nekhwalithi yokuphrinta.
Ukuqina kwe-Emulsion: Ama-inks akhuphukela ama-emulsions, njengaleyo esetshenzisiwe e-Lithography, i-hec ithuthukisa ukuqina kwe-emulsion, ukuvimbela ukuhlukaniswa kwesigaba kanye nokuqinisekisa ukusetshenziswa okufanayo.

2.3 Ukuhleleka kwefilimu
I-HEC inikela ngezakhiwo ezenziwe ngefilimu zama-inks. Ifilimu elizinzile nelinganemkhiqizo libalulekile ekunciphiseni nasekubukekeni kwezinto eziphrintiwe:

I-Coaging Unipromity: Uma isetshenziswa kuma-substrate, i-HEC isiza ukwakha ifilimu elingaguquki enamathela kahle, ithuthukise ikhwalithi yesendlalelo ephrintiwe.
Ukuvikelwa okungaphezulu: amandla abumba amafilimu we-HEC futhi anezela ungqimba lokuvikela izinto eziphrintiwe, athuthukise ukumelana nokumelana kwawo ezintweni ze-abrasion kanye nezemvelo.

2.4 Ukugcinwa kwamanzi
Amandla ka-HEC okugcina amanzi adlala indima ebalulekile ekusebenzeni kwama-inks asuselwa emanzini:

I-Sorner Control: I-HEC isiza ukulawula izinga lokumisa ama-inks. Lokhu kuwusizo ikakhulukazi ezinqumweni zokuphrinta lapho ukuyomiswa kancane kancane kudingeka ukugwema izingqinamba njengekhwalithi yokuphrinta engeyinhle.
Ukusetshenziswa: Ngokugcina amanzi, i-HEC iqinisekisa ukuthi uyi-ink igcina ukuvumelana okusebenzayo kwesikhathi eseluliwe, okubaluleke kakhulu ekuphrintweni okufana nokuphrinta kwesikrini kanye neFlography.

2.5 ukuhambisana nezinye izinto
I-HEC iyahambisana nohlu olubanzi lwezakhi ze-ink, kufaka phakathi imibala, amabhayisiki kanye nama-solvents:

Ukuvumelana nezimo: Imvelo engeyona eye-ionic ye-HEC ikuvumela ukuthi isebenze kahle ngezithasiselo ezahlukahlukene kanye nama-modifiers asetshenziswa ekusungulweni kwe-ink, ukuhlinzeka ngamakhemikhali ngokuguquguquka ukuze kufezeke izici ezithile zokusebenza.
I-Solubity kanye nokuqina: I-HEC incane emanzi abandayo nawashisayo, futhi ihlala iqinile ngaphezu kwebanga le-PH ebanzi, okwenza lilungele izinhlelo ze-ink ezahlukahlukene.

I-3. Izicelo ezithile ze-ink izinhlobo ezahlukene

3.1 Izikrini zokuphrinta zesikrini
Ekunyatheliseni kwesikrini, lapho ama-inks kufanele abe khona ubukhulu ukuvikela ukusakazeka nge-mesh, i-hec isetshenziselwa ukulawula ukuqonda futhi yenza ngcono incazelo yokuphrinta. Kuqinisekisa ukuthi uyinki unokuvumelana okulungile ukunamathela esikrinini futhi udlulise ngokunembile kwi-substrate.

3.2 Ama-Inks we-Flezographic and Gravere
Okwe-Inks ye-Flezographic and Gravere, edinga amaphrofayli athile we-visucosity ngokudluliswa okulungile nokunamathela, i-HEC isiza ekufezeni izici ezifanele zokugeleza. Kuqinisekisa ukuthi ama-inks akha umncane, noma ungqimba amapuleti wokuphrinta futhi ngokulandelayo engxenyeni engezansi.

3.3 inkjet inks
Ku-inkjet inks, ikakhulukazi ukwakheka kwamanzi, izinsiza ze-HEC ngokulawula i-visconging ukuze kuqinisekiswe i-Jetting ebushelelezi futhi kuvikele ukuvalwa kwe-nozzle. Kuyasiza nokugcina ukumiswa kwemibala, kubalulekile ukukhiqiza ama-Prints asezingeni eliphakeme, asebenzayo.

3.4 Ama-Inks we-Coating
Ekuhlolweni kwama-coating, njengalezo ezisetshenziselwa ukuqeda okucwebezelayo noma izingqimba ezivikelayo, i-hec inomthelela ekwakhekeni kwefilimu ebushelelezi, efanayo. Kuyasiza ekufezeni izakhiwo ezithandekayo zobuhle nezisebenzayo ze-coating, kufaka phakathi isicwebe, ukuqina, kanye nokumelana nezinto zangaphandle.

4. Izinzuzo zokusebenzisa i-HEC ku-Inks

Ikhwalithi ye-Phrinta eyenziwe ngcono: Ngokuhlinzeka nge-viscosity engaguquki nokumiswa kwezithombe ezinzile, i-HEC ithuthukisa ikhwalithi yokuphrinta ephelele, kufaka phakathi ukunemba kombala kanye nokubukhali.
Ukusebenza kahle kokusebenza: Ukugcinwa kwamanzi kanye nokuguqulwa kwe-Rheology Ukuguqulwa kwe-HEC kufaka isandla ezinqubweni zokuphrinta ezisebenza kahle, kunciphisa isikhathi sokuphumula esibangelwa yizingqinamba ezinjenge-nowny cloging noma ukugeleza kwe-ink e-unorn.
Okuhlukahlukene

5. Ukucatshangelwa Kwezemvelo Nezokuphepha

I-HEC isuselwa ku-cellulose, insiza evuselelekayo, okwenza kube yikhetho elinobungani bezemvelo ngokuqhathaniswa nama-polymers okwenziwa. I-biodegradeatability futhi iyanezela ezinhlelweni zayo zemvelo. Ngokwengeziwe, i-HEC ivame ukubhekwa njengephephile ukuze isetshenziswe kuma-inks, ibeka ubungozi obuncane kwezempilo nokuphepha lapho iphathwe kahle.

IHydroxYethyl Cellulose (I-HEC) iyingxenye ebalulekile ekwakhiweni kwama-ink wanamuhla, enikeza uhla lwezinzuzo kusuka ekunikezelweni kwe-Viscosity kanye nokuzinza kwefilimu nokugcinwa kwamanzi. Ukuguquguquka kwayo kanye nokuhambisana nezinhlelo ezahlukahlukene ze-Ink zenza kube yisengezo esibalulekile sokuthola ukusebenza kwe-ink yekhwalithi ephezulu, engaguquki, nokusebenza kahle. Njengoba imboni ye-INK iyaqhubeka nokuvela, iqhaza lika-HEC kungenzeka likhule ngokuqhubekayo, liqhutshwa ngezimo zalo kanye nezakhiwo ezisebenzayo.
