Isebenzisa i-inki eyiyo kwiiprinti ezikhazimlayo, ezihlambekayo, nezihlala ixesha elide. Inkqubo yokuPrinta ye-M&R's QUATRO™ Direct to Film Transfer Printing inika imifanekiso esemgangathweni ophezulu, eqinileyo kwiintlobo ngeentlobo zeempahla kunye neentlobo zelaphu. Ibandakanya ukuprinta uyilo kwifilimu ekhethekileyo ye-PET ene-inki ze-inkjet ezikhethekileyo kwaye emva koko ifake umaleko wokuncamathelisa.

IYunivesithi yaseBorås iphuhlise inkqubo yokuprinta yedijithali ezinzileyo. Inciphisa kakhulu ukusetyenziswa kwamanzi kunye nokukhutshwa kwezinto eziyingozi. Isebenzisa i-inki yepigment kunye nee-inki ezithintela amanzi ezingenazo ii-fluorocarbons eziyingozi kwindalo.

Ukusebenzisa ii-Agents zokulungisa emva kokudaywa

Iimpahla zemidlalo zijongene nemingeni yokuba zimanzi ngokukhawuleza ngenxa yokufuma okuphezulu kunye nokuvezwa kokubila. Oku kunokukhawulezisa ukufuduka kwedayi kunye nokudluliselwa kombala. Ukukhawuleza kokuhlikihla okumanzi kudla ngokuba sezantsi kuba amanzi athambisa idayi, okwenza kube lula ukuba amasuntswana ahlukane. Ukusetyenziswa kwezilungisi zedayi kunye neearhente emva konyango kunokuphucula kakhulu iimpawu zokuqina, ngakumbi kwikotoni kunye nemixube. Oku kujongana nale micimbi kwimpahla yezemidlalo.

Izilungisi zedayi eziphambili, njengeDisperse Dyes Fixer RG-E906, zenzelwe ukwenza unxibelelwano oluqinileyo neemolekyuli zedayi kwilaphu. Le nkqubo ivala umbala ngempumelelo. Ikhokelela ekuphuculeni okukhulu ekuqineni okumanzi kwelaphu. Oku kubandakanya ukuqina okuphuculweyo kokuhlamba, ukuqinisekisa ukuba amalaphu agcina umbala wawo wokuqala emva kokuhlamba izihlandlo ezininzi. Ikwaphucula ukuqina kokubila, ithintela ukopha kombala xa ivezwa kukubila. Oku kubaluleke kakhulu kwiimpahla ezisebenzayo.

Iinkqubo Zokuhlamba Ezisebenzayo

Iinkqubo zokuhlamba kakuhle zibalulekile ekususeni iidayi ezingaguqukiyo kwiimpahla zemidlalo ezidaywe ngendlela eguquguqukayo. Oku kuthintela ukopha kombala kwaye kuqinisekisa ukuba umbala awugugi.

1. Ukuhlamba kokuqala (Inqanaba lokuxuba): Qala ngokuhlanjwa ngamanzi abandayo, kulandele ukuhlamba ngamanzi ashushu (40-50°C) imizuzu eli-10. Eli nqanaba lijolise ekususeni iityuwa, ii-alkalis, kunye needayi ezingaguqukiyo kumphezulu wefayibha, ukulungiselela isepha esebenzayo ngakumbi.
2. Ukungathathi cala (Ukhetho): Ukuba iidayi azinawo amandla okumelana ne-alkali, zinyibilikise kwindawo yokuhlamba i-acetic acid ngaphambi kokuyigalela ngesepha ukuthintela i-hydrolysis kwaye uphephe utshintsho lombala (umz., iidayi ezibomvu ezijika zibe tyheli).
3. Inkqubo Yokusepha: Eli nyathelo likhuthaza ukusasazeka kweedayi ezingaguqukiyo ezifakwe i-hydrolyzed ukusuka ngaphakathi kwifayibha ukuya kumphezulu nakwisisombululo sokuhlamba. Ukunyuka kobushushu kwandisa ukusasazeka kwaye kunciphisa ukunamathelana kwedayi, kwandisa ukuxinana. Ziphephe iisepha zesepha eziqhelekileyo kunye nee-surfactants ezingezizo i-ionic kuba azikhawulezisi ukusasazeka. Izongezo ze-cationic zinokuphucula ukucoca kodwa zinokubangela ukuxinana kwakhona. Izincedisi ezikhethekileyo ezine-affinity ephezulu yedayi zinokwenza ii-complexes ukuthintela ukuxinana kwakhona kunye nokuphucula ukukhawuleza konyango olumanzi.
4. Ukuhlamba Amanzi Ashushu Emva Kokusepha: Hlamba ngamanzi ashushu kwi-70°C ungadluli kwimizuzu eli-10 ukuze unyibilikise kwaye ususe idayi eseleyo.
5. Ukuhlamba Amanzi Abandayo Okokugqibela: Gqibezela ngokuhlamba ngamanzi abandayo.

Injongo iyonke kukusondeza i-pH yelaphu kufutshane ne-neutral. Qinisekisa ukuba ii-electrolytes kwisisombululo sesepha azidluli kwi-2g/L, njengoko oku kunciphisa ukusasazeka kwedayi e-hydrolyzed kunye nokukhawuleza kokuhlamba. I-alkali eseleyo inokuchaphazela ukukhanya kombala xa yomile.

Ukuze ufumane indlela esebenzisekayo ngakumbi, cinga ngala manyathelo:

1. Ukuhlamba ngamanzi abandayo (Kubotshelelwe ilaphu): Gcina ilaphu libotshiwe kwaye uhlambe ngamanzi abandayo ahambayo de amanzi aqale ukuphuma. Oku kunceda ukuthintela ukufuduka kombala kunye nokungcola, ingakumbi kwiindawo ezimhlophe, kwaye kususa i-soda ash alkali.
2. Hlamba Amanzi Afudumeleyo Uze Udibanise: Nyusa ubushushu bamanzi ukuze bufudumale kwaye ukhulule ilaphu ngelixa uhlamba.
3. Ukuhlamba ngamanzi ashushu ngesepha yokuwasha: Hlamba ngamanzi ashushu usebenzisa isepha yokuhlamba izitya okanye isepha yokuhlamba impahla. Imiyalelo yokuqala yeProcion MX icebisa ukuba uhlambe kumaqondo obushushu asondele ekubileni kangangoko kunokwenzeka, kodwa iingcebiso ezisebenzayo zicebisa ukuba usebenzise amanzi ashushu kakhulu okhululekileyo ngawo. Eli nyathelo linceda ukususa idayi ekhululekileyo nengagungqiyo.
4. Ukuhlamba Amanzi Abandayo: Hlamba ngamanzi abandayo emva kokuhlamba okushushu.
5. Phinda ukuba kuyimfuneko: Phinda umjikelo wokuhlamba ukuba kuyimfuneko de kungabikho dayi iphumayo kwaye imijikelo yokuhlamba/yokuhlamba icocekile.

Ukuseta kokugqibela kobushushu ukuze uzinze ngedayi

Ukuseta ubushushu bokugqibela kunceda kakhulu ekuhlanjweni nasekukhawulezisweni kwempahla yezemidlalo eyenziweyo edayiweyo. Umatshini wokushicilela ubushushu udlala indima ebalulekileyo kwinkqubo yokuprinta i-sublimation. Iqinisekisa ukuba i-inki ye-sublimation ingena kwiifayibha zezinto. Oku kubangela ukuba kubekho iiprinta ezingagcini nje ngokuba zikhanya kodwa ezihlala ixesha elide kakhulu. I-inki iba yinxalenye ye-substrate ngokwayo. Ngokungafaniyo neendlela zemveli apho i-inki ihlala phezu komphezulu wezinto, i-sublimation ifaka uyilo ngaphakathi kwiifayibha, inyusa ukuqina kunye nomtsalane obonakalayo.

Le nkqubo ibandakanya amanyathelo aliqela abalulekileyo:

1. Ukusasazwa kwedayi: Ii-inki ze-sublimation ziqulethe iidayi ezisasazekileyo. 380–400°F (193–204°C) ubushushu, ezi dayi zitshintsha ukusuka ekubeni ziqinileyo zibe yigesi.
2. Ukuvulwa kwePolymer: Xa amaqondo obushushu aphezulu, imixokelelwane yepolymer yepolyester iyakhululeka. Oku kuvumela iimolekyuli zedayi zegesi ukuba zingene kwifayibha.
3. Ukupholisa kunye nokutshixa: Njengoko ilaphu liphola, iintambo zepolymer ziyavaleka, zivala iimolekyuli zedayi ngaphakathi kwesakhiwo. Isiphumo sisibopho esihlala sihleli esingamelani nokuhlanjwa, ukukrazulwa, kunye nokuvezwa yi-UV.

Iintlobo ezahlukeneyo zelaphu zifuna iimeko ezithile zokubeka ubushushu ukuze kufezekiswe ukugcinwa kombala okufanelekileyo:

Uhlobo lwelaphu	Ubushushu (°F)	Ixesha lokuhlala (Imizuzwana)	Inqanaba loxinzelelo	Ukugcinwa kombala emva kokuhlamba (%)
I-100% yePolyester	380–400	45–60	Phakathi (≈40 psi)	90–95%
65/35 Poly-Cotton	375–385	50–60	Phakathi (≈40 psi)	70–75%
50/50 Poly-Cotton	370–380	60–70	Phakathi-Phezulu (≈50 psi)	50–55%
I-100% yeKotoni + Ukwaleka	360–375	60–75	Phakathi-Phezulu (≈50 psi)	65–70%

Umzekelo, iihempe zepolyester ezifakwe ubushushu kwi-390°F kangangemizuzwana engama-50 zigcine malunga ne-90% yesisombululo kunye nokukhanya emva kokuhlamba izihlandlo ezingama-25. Iihempe zekotoni ezinganyangwanga, kusetyenziswa useto olufanayo, zifumene kuphela malunga ne-30% yobuninzi bombala kwaye ziphela kakhulu emva kokuhlamba izihlandlo ezili-10 kuphela. Ikhotoni ene-poly coating iphucuke yaya kwi-65–70% yokugcina, kodwa oku kongeze malunga ne-20% yeendleko ezongezelelweyo ngeyunithi nganye.
