1.Isingeniso
IHydroxyethyl cellulose (HEC) iyi-polymer eguquguqukayo etholakala ku-cellulose, esetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezinhle kakhulu ze-rheological, amandla okugcina amanzi, nokuhambisana nezinye izinto.Emkhakheni wokwenziwa kweyinki, i-HEC isebenza njengengxenye ebalulekile, idlulisela izici ezifiselekayo ezifana nokulawula i-viscosity, ukuzinza, nokunamathela.
2.Ukuqonda i-HEC ku-Ink Formulations
Ekwenziweni kukayinki, i-HEC isebenza njenge-ejenti ejiyayo, ethuthukisa i-viscosity ukuze kuzuzwe izici zokugeleza ezifanele.Imvelo yayo ye-hydrophilic iyenza ikwazi ukugcina amanzi ngendlela efanele ngaphakathi kwe-matrix kayinki, ivimbele ukomiswa ngaphambi kwesikhathi nokugcina ukungaguquguquki phakathi nezinqubo zokuphrinta.Ngaphezu kwalokho, i-HEC ibonisa ukuziphatha kokunciphisa i-shear, okusho ukuthi inciphisa i-viscosity ngaphansi kwengcindezi ye-shear, yenza kube lula ukusetshenziswa kwama-substrates ahlukahlukene.
3.Izinzuzo Zokufaka I-HEC Kuyinki
I-Viscosity Control: I-HEC inikeza ukulawula okunembile kokubonakala kweyinki, okubalulekile ekuzuzeni ikhwalithi yokuphrinta oyifunayo kanye nokusebenza kuzo zonke izindlela zokuphrinta ezihlukene.
Ukuzinza Okuthuthukisiwe: Ngokwenza i-matrix ezinzile, i-HEC ivimbela i-sedimentation kanye nokuhlukaniswa kwesigaba, iqinisekisa ukusatshalaliswa kwe-inki efanayo kanye nokuzinza kwesikhathi eside.
Ukunamathela Okuthuthukisiwe: Izakhiwo zokunamathela ze-HEC zikhuthaza ukunamathela okungcono phakathi kweyinki ne-substrate, okuholela ekuthuthukisweni kokuqina kokuphrinta kanye nokumelana nokuhuzuka.
Ukugcinwa Amanzi: Amakhono okugcina amanzi e-HEC anciphisa ukuhwamuka ngesikhathi sokuphrinta, anciphisa isikhathi sokumisa uyinki futhi avimbele ukuvala umlomo wombhobho kumaphrinta we-inkjet.
Ukuhambisana: I-HEC ihambisana nezinhlobonhlobo zezithasiselo ze-inki nemibala, okuvumela ukwakheka kwe-inki okuguquguqukayo okuhambisana nezidingo ezithile zokuphrinta.
Ubungane Bemvelo: Njengepolymer esekwe ku-bio, i-HEC inikela ekusimameni kokwakheka kukayinki, ukuhambisana nemikhuba eco-friendly embonini yokunyathelisa.
4.Ukucatshangelwa Okusebenzayo Kwesicelo se-HEC
I-Optim Concentration: Ukugxila kwe-HEC ekwakhiweni kukayinki kufanele kuthuthukiswe ngokucophelela ukuze kuzuzwe i-viscosity oyifunayo ngaphandle kokuphazamisa ezinye izici zikayinki.
Ukuhlola Ukuhambisana: Ngaphambi kokukhiqizwa kwezinga elikhulu, ukuhlola ukuhambisana nezinye izingxenye zikayinki nama-substrates kubalulekile ukuze kuqinisekiswe ukuzinza nokusebenza.
Ukulawula Usayizi Wezinhlayiyana: Ukusatshalaliswa kosayizi wezinhlayiyana ze-HEC kufanele kulawulwe ukuze kuvinjelwe ukuvaleka kwezinto zokunyathelisa, ikakhulukazi ezinhlelweni zokuphrinta ze-inkjet.
Izimo Zokugcina: Izimo ezifanele zokugcina, okuhlanganisa nokulawula izinga lokushisa nomswakama, zibalulekile ekugcineni ubuqotho bokwakheka kukayinki okusekelwe ku-HEC nokwelula isikhathi seshelufu.
Ukuthobela Umthetho: Ukuthobela izindinganiso zokulawula, njengalezo eziphathelene nokuphepha, impilo, kanye nomthelela emvelweni, kufanele kuqinisekiswe uma kusetshenziswa i-HEC ekwenziweni kukayinki.
5.Case Studies kanye nezicelo
Ukuphrinta kwe-Flexographic: Amayinki asekelwe ku-HEC avame ukusetshenziswa ekuphrinteni kwe-flexographic yezinto zokupakisha, enikeza ukuphrinta okuhle kakhulu, ukunamathela, nokuvumelana kombala.
Ukuphrinta Kwendwangu: Ekuphrinteni kwendwangu, i-HEC idlulisela isilawuli se-viscosity futhi iwashe ukushesha koyinki, iqinisekisa ukuphrinta okunamandla nokuqina ezindwangu ezihlukahlukene.
Ukuphrinta kwe-Inkjet: I-HEC isebenza njengengxenye eyinhloko ekwakhiweni kwe-inkjet, ihlinzeka ngokuzinza kwe-viscosity futhi ivimbele ukuvala umlomo wombhobho, ikakhulukazi ezinhlelweni zokuphrinta ezinesivinini esikhulu.
Ukuphrinta kweGravure: Oyinki abasuselwa ku-HEC ekuphrinteni kwegravu babonisa izakhiwo zokugeleza nokunamathela okuphezulu, okuholela ekuphrinteni kwekhwalithi ephezulu kuma-substrates ahlukahlukene njengephepha, ipulasitiki, nensimbi.
I-Hydroxyethyl cellulose (HEC) idlala indima ebalulekile ekwakhiweni kukayinki kuzo zonke izinhlelo zokusebenza zokuphrinta ezihlukahlukene, enikeza ibhalansi yokulawula i-viscosity, ukuzinza, nokunamathela.Ukuguquguquka kwayo okuhlukahlukene, okuhambisana nobungane bemvelo, kuyenza ibe yinketho ekhethwayo kubakhiqizi beyinki abafuna ukuthuthukisa ikhwalithi yokuphrinta nokusebenza kuyilapho bebambelela emikhubeni eqhubekayo.Ngokuqonda izindlela nezinzuzo ze-HEC ekwakhiweni kukayinki, amaphrinta angasebenzisa amandla awo ukuze athole imiphumela ephakeme emizamweni yawo yokuphrinta.
