Intshayelelo: Inkqubo yokudlulisa i-thermal, inkqubo eqhelekileyo kunyango lomphezulu wezinto zokupakisha izithambiso, kuba kulula ukuprinta, kwaye umbala kunye nomzekelo unokwenziwa ngokwezifiso. Yinkqubo ekhethwa ngabanini beempawu. Oku kulandelayo kuhlelwa nguI-RB PACKAGE.Makhe sabelane ngeengxaki eziqhelekileyo zomgangatho kunye nezisombululo kunye nezinto ezinefuthe lokudluliselwa kwe-thermal, kwireferensi yakho kwikhonkco lokubonelela le-Youpin:
Ukutshintshwa kobushushu
Inkqubo yokudlulisa i-Thermal ibhekiselele kwiphepha lokudlulisa eliqatywe ngee-pigments okanye iidayi njengento ephakathi, ngokufudumeza, ukuxinzelela kunye nezinye iindlela zokudlulisa ipateni yepateni ye-inki ephakathi ukuya kwindlela yokushicilela. Umgaqo osisiseko wokutshintshwa kwe-thermal kukudibanisa ngokuthe ngqo i-inki-coated medium kunye ne-substrate. Ngokufudumeza kunye noxinzelelo lwentloko yoshicilelo lwe-thermal kunye ne-cylinder ye-impression, i-inki kwi-medium iya kunyibilika kwaye idluliselwe kwi-substrate ukuze ifumane okufunwayo kumbandela oshicilelweyo.
01Izinto ezichaphazelayo zokutshintshwa kwe-thermal
I-1) Intloko yokushicilela i-Thermal
Intloko yoshicilelo lwe-thermal ikakhulu iqulunqwe ngumaleko okhuselayo wefilimu encamathelayo phezulu, ifilimu encamathelayo esezantsi ekhuselayo kunye nezinto zokufudumeza. Isixhobo sokufudumeza sisikrini sesilika esiqhubayo. Ngoncedo lobushushu olwenziwa yi-voltage pulse, amasuntswana arhabaxa omaleko we-inki wecandelo lomzobo agxininiswe kwaye anyibilike ukuze agqibezele ukuhanjiswa kweinki.
Isantya soshicilelo sokudluliselwa kwe-thermal sixhomekeke kwixesha elifunekayo kumgca ngamnye wemizobo kunye nokubhaliweyo. Ngoko ke, intloko yokudlulisa i-thermal kunye nephepha lokudlulisa kufuneka libe nokutshintshwa kobushushu obuhle, ukwenzela ukuba ubushushu obuveliswa yinto yokufudumala bukwazi ukudlula ngokukhawuleza kwinqanaba elikhuselayo, i-substrate yephepha lokudlulisa kunye ne-gap kwaye ekugqibeleni ukuya kumphezulu we-substrate ukuqinisekisa. ukuba i-inki inexesha elaneleyo lokudlulisela.
2) I-inki
Ukubunjwa kwe-inki yokudlulisa i-thermal ngokuqhelekileyo kumacandelo amathathu: i-pigment (i-pigment okanye idayi), i-wax kunye neoli, phakathi kwayo i-wax iyingxenye ephambili ye-inki yokudlulisa i-thermal. Ukwakhiwa okusisiseko kwe-inki yokudluliselwa kwe-thermal jikelele kunokubhekisa kwiThebhile yoku-1.
Itheyibhile 2 ngumzekelo woshicilelo lwe-inki yokutshintsha ubushushu kwesikrini. I-N-methoxymethyl polyamide inyibilika kwi-benzyl alcohol, toluene, ethanol kunye nezinye izinyibilikisi, ii-pigments ezimelana nobushushu kunye ne-bentonite zongezwa ukuze zivuse, kwaye emva koko ziphantsi kwii-inki zokuprinta iSkrini. I-inki iprintwa kwi-carrier (efana nephepha lokudlulisa i-thermal) usebenzisa indlela yokushicilela isikrini, kwaye emva koko ilaphu licinezelwe kwaye lidluliselwe.
Xa kushicilelwa, i-viscosity yee-inks ezahlukeneyo ihambelana ngokuthe ngqo nobushushu bokufudumala, kwaye ubushushu bokufudumala kunye ne-viscosity ye-inki kufuneka ilawulwe ngokungqongqo. Ukuziqhelanisa kubonise ukuba xa ubushushu bokufudumala buyi-60～100 ℃, xa i-inki inyibilika, ixabiso le-viscosity ye-inki lizinzile malunga ne-0.6 Pa·s, eyona nto ifanelekileyo. Ngokubanzi, okukhona i-inki isondele kweli lizwe, kokukhona intsebenzo yokudlulisela ingcono.
Kwiminyaka yakutshanje, ngokuphuculwa kweteknoloji yephakheji ye-rainbow yase-Shanghai, ubushushu bokugcinwa kweemveliso eziprintiweyo bonyuswe ukusuka kwi-45 ℃ yokuqala ukuya kwi-60 ℃, ethe yandisa kakhulu uluhlu lwesicelo sokudluliselwa kwe-thermal. Ukongezelela, ukusetyenziswa kwee-pigments ezicacileyo okanye iidayi ezicacileyo kunika umphumo omuhle we-hue kwiprints zombala.
3) Dlulisa imidiya
Ii-substrates ezahlukeneyo zineepropati ezahlukeneyo, ngoko ke xa ukhetha iphepha lokudlulisa, kufuneka ubeke ingqalelo kwizinto ezilandelayo zokubhekisela kwi-substrate.
①Ukusebenza komzimba
Iimpawu ezibonakalayo zephepha lokudluliselwa ziboniswe kwiThebhile yesi-3.
Ezi zingasentla ziimpawu ezibonakalayo zesubstrates ezintathu zephepha lokudlulisa thermal. Le miba mithathu ilandelayo inokuqwalaselwa xa ukhetha:
Ubukhulu be-substrate kufuneka bungabi ngaphezu kwe-20 μm;
I-substrate kufuneka ibe neqondo eliphezulu lokugudiswa ukuze kuqinisekiswe izinga lokudluliselwa kwe-inki;
I-substrate kufuneka ibe namandla okwaneleyo ukuqinisekisa ukuba ayiyi kukrazulwa ngexesha lokuhanjiswa kwephepha kunye nokuprintwa.
② Iimpawu zekhemikhali
Okulungileyo kunye nokubambelela kwe-inki zizibonakaliso ezimbini ezibalulekileyo zeempawu zeekhemikhali ze-substrate yephepha lokudlulisa. Kwimveliso, iipropati zeekhemikhali zephepha lokudlulisa ngqo zichaphazela umgangatho wokushicilela. Ukuba iphepha lokutshintshela alikwazi ukwenza i-inki ibambelele kakuhle, okanye isixa se-inki asikwazi ukuveliswa kwimveliso, kuya kubangela inkunkuma yokushicilela. Inkqubo efanelekileyo yokushicilela kunye nokuprinta okulungileyo kufuneka kusekelwe ekubambeni kakuhle iimpawu zekhemikhali zephepha lokudlulisa.
③Ukusebenza kakuhle kwe-thermal
Ekubeni inkqubo yokudlulisa ifunyenwe ngeendlela eziphezulu zokushisa, izinto eziphathekayo zephepha lokudlulisa kufuneka zikwazi ukumelana nefuthe lobushushu bokudlulisa kunye nokugcina iimpawu zingatshintshi. Ngokuqhelekileyo, ingaba ukusebenza kwe-thermal ye-substrate yephepha lokudluliselwa kwe-thermal kulungile kunokubonakaliswa kwezi zinto zilandelayo:
Ukunciphisa ukuxhathisa ubushushu be-substrate ekwazi ukumelana nobushushu, i-thinner the thick, ingcono ukuhanjiswa kobushushu, kunye nokusebenza kwayo kwe-thermal;
Ukuguda I-substrate surface, isezantsi ukuxhathisa ubushushu kunye nokusebenza ngcono kwe-thermal;
Ubushushu bentloko yoshicilelo lwe-thermal ekwazi ukumelana nobushushu ngokuqhelekileyo malunga ne-300 ℃, kwaye i-substrate kufuneka ikwazi ukuqinisekisa ukuba umsebenzi oyintloko awutshintshi kule bushushu.
4) I-Substrate
IiSubstrates ezinomphezulu omncinci orhabaxa zinomgangatho ongcono wokuprinta, olona phawu lubalulekileyo lokudluliselwa kwe-thermal. Ngenxa yokuba indawo enqabileyo ye-substrate ibonisa ukuba i-substrate inamandla amakhulu, i-inki kwiphepha lokudlulisa inokudluliselwa kwi-substrate kakuhle, kwaye inqanaba elifanelekileyo kunye nethoni inokufumaneka; kodwa kurhabaxa kakhulu kuyakuchaphazela umgangatho we-inki Ugqithiso oluqhelekileyo aluncedi kufezekiso lwenkqubo yoshicilelo.
