Inkqubo ye-Sublimation
I-sublimation yinkqubo yeekhemikhali. Ngemigaqo elula (r), kulapho isiqina sijika sibe yirhasi, ngoko nangoko, ngaphandle kokudlula kwinqanaba lolwelo phakathi. Xa ubuza ukuba yintoni i-sublimation printing, inceda ukuqonda ukuba ibhekisela kwidayi ngokwayo. Kwakhona sibiza le dayi-sublimation, njengoko iyidayi etshintsha isimo.
Ushicilelo lwe-sublimation lubhekiselele kushicilelo lwe-sublimation, oko kukuthi, ushicilelo lwe-Thermal sublimation.
1. Ithekhnoloji yokuprinta yokudlulisa ehambisa iphethini yombala kwipatheni kwinqwelomoya yempahla okanye ezinye ii-receptors ngokusebenzisa ukushisa okuphezulu.
2. Iiparamitha ezisisiseko: Ukuprintwa kwe-Sublimation yiteknoloji yokushicilela yokudlulisa, ebhekisela kwi-pigments yokushicilela okanye idayi kwiphepha, i-rubber okanye abanye abathwali. Ngokwezi mfuno zingentla, iphepha lokudlulisela kufuneka lihlangabezane nale migangatho ilandelayo:
(1) Hygroscopicity 40--100g/㎡
(2) Amandla okukrazula malunga ne-100kg/5x20cm
(3) Ukungena komoya 500---2000l/min
(4) Ubunzima 60--70g/㎡
(5) ph ixabiso 4.5--5.5
(6) Ukungcola akukho
(7) Iphepha lokudlulisela kukhethwa ukuba lenziwe ngepulp ye-softwood. Phakathi kwabo, i-pulp yeekhemikhali kunye ne-pulp yomatshini nganye ingcono. Oku kunokuqinisekisa ukuba iphepha le-decal aliyi kuba brittle kwaye liphuzi xa liphathwa kwiqondo lokushisa eliphezulu.
Transfer Print
Oko kukuthi, ukutshintshela ushicilelo.
1. Enye yeendlela zokuprinta i-textile. Yaqala ekupheleni kweminyaka yee-1960. Indlela yokushicilela apho idayi ethile iqala ukuprintwa kwezinye izinto ezifana nephepha, kwaye ipateni idluliselwe kwilaphu ngokucinezela okushushu kunye nezinye iindlela. Isetyenziswa kakhulu ukuprinta iimpahla ezinithiweyo zefiber fiber kunye nempahla. Ushicilelo lokutshintshela luhamba ngeenkqubo ezinje nge-sublimation yedayi, ukufuduka, ukunyibilika, kunye ne-inki yokuxobula.
2. Iiparamitha ezisisiseko:
Idayi ezifanelekileyo zoshicilelo kufuneka zihlangabezane nale miqathango ilandelayo:
(1) Idayi zoshicilelo olugqithiselwayo kufuneka zithotywe ngokupheleleyo kwaye zilungiswe kwiintsinga ezingaphantsi kwe-210 °C, kwaye zinokufumana ukushesha kokuhlamba okulungileyo kunye nokukhawuleza koku-ayina.
(2) Iidayi zoshicilelo lokutshintshela zinokuguqulwa ngokupheleleyo kwaye zitshintshwe zibe yi-gas-phase yedayi macromolecules emva kokufudunyezwa, igxininiswe kumphezulu welaphu, kwaye inokusasaza kwifiber.
3
(4) Idayi yokushicilela kufuneka ibe nombala oqaqambileyo noqaqambileyo.
Iphepha lokutshintshela elisetyenzisiweyo kufuneka libe nezi mpawu zilandelayo:
(1) Kufuneka kubekho ukomelela okwaneleyo.
(2) Ukudityaniswa kwe-inki yombala kuncinci, kodwa iphepha lokutshintshela kufuneka libe nokugquma kakuhle kwe-inki.
(3) Iphepha lokudlulisa akufanelekanga ukuba ligqwethekile, libe brittle kwaye libe tyheli ngexesha lenkqubo yoshicilelo.
(4) Iphepha lokudlulisa kufuneka libe ne-hygroscopicity efanelekileyo. Ukuba i-hygroscopicity ihlupheke kakhulu, iya kubangela ukuba inki yombala idibanise; ukuba i-hygroscopicity inkulu kakhulu, iya kubangela ukuguqulwa kwephepha lokudlulisa. Ngoko ke, i-filler kufuneka ilawulwe ngokungqongqo xa ivelisa iphepha lokudlulisa. Kufanelekile ngakumbi ukusebenzisa i-semi-filler kwishishini lephepha.
I-Sublimation vs Ukudluliselwa kobushushu
- Siyawubona umahluko phakathi kwe-DTF kunye ne-Sublimation.
- I-DTF isebenzisa ifilimu ye-PET njengendawo ephakathi, ngelixa i-Sublimation isebenzisa iphepha njengento ephakathi.
I-2.Print Runs-Zombini iindlela zifaneleka kakuhle kushicilelo oluncinci olubalekayo, kwaye ngenxa yeendleko zokuqala zedayi-sub, ukuba uya kuprinta isikipa esinye rhoqo emva kweenyanga ezimbalwa, emva koko unokufumana ukuhanjiswa kobushushu. ngcono kuwe.
3.Kwaye i-DTF inokusebenzisa i-inki emhlophe, kwaye i-Sublimation ayisebenzisi.
4. Umahluko omkhulu phakathi kokutshintshwa kobushushu kunye ne-sublimation kukuba nge-sublimation, yi-inki kuphela edlulisela kwizinto eziphathekayo. Ngenkqubo yokudlulisa ubushushu, ngokuqhelekileyo kukho i-transfer layer eya kudluliselwa kwizinto eziphathekayo.
I-5.Ukudluliselwa kwe-DTF kunokufikelela kwimifanekiso esemgangathweni yesithombe kwaye iphezulu kune-sublimation. Umgangatho womfanekiso uya kuba ngcono kwaye ucace ngakumbi ngomxholo ophezulu we-polyester wendwangu. Kwi-DTF, uyilo kwilaphu livakala lithambile xa libamba.
6. Kwaye i-Sublimation ayisebenzi kwilaphu lomqhaphu, kodwa i-DTF ifumaneka phantse kulo lonke uhlobo lwelaphu.
Ngqo kwiMpatho (DTG) vs i-Sublimation
- IMisebenzi yokuShicilela – i-DTG ikwafanelene noshicilelo oluncinci olubalekayo, olufana noshicilelo oluncinci. Uya kufumana nangona kunjalo ukuba indawo yoshicilelo kufuneka ibe ncinci kakhulu. Ungasebenzisa idayi-sub ukugquma ngokupheleleyo ingubo ngokuprintwa, ngelixa i-DTG ikukhawulela. Isiqingatha semitha yesikwere iya kuba yityhala, kuyacetyiswa ukuba uncamathele malunga ne-11.8″ ukuya kwi-15.7″.
- Iinkcukacha-Nge-DTG i-inki iyasasaza, ngoko ke imizobo kunye nemifanekiso eneenkcukacha ziya kubonakala zipikelise ngaphezu kokuba zenza kwiscreen sekhompyuter yakho. Ukuprintwa kwe-sublimation kuya kunika iinkcukacha ezibukhali nezintsonkothileyo.
- Imibala - I-Fades, i-glows kunye ne-gradients ayinakuphinda iphinde yenziwe nge-DTG yokushicilela, ngakumbi kwiingubo ezinemibala. Kwakhona ngenxa yemibala yemibala esetyenzisiweyo eluhlaza kunye nepinki, kunye nemibala yensimbi ingaba ngumba. Ukuprintwa kwe-sublimation kushiya iindawo ezimhlophe zingaprintwa, ngelixa i-DTG isebenzisa ii-inki ezimhlophe, eziluncedo xa ungafuni ukuprinta kwizinto ezimhlophe.
- Ubomi obude - i-DTG isebenzisa ngokoqobo inki ngqo kwisambatho, kanti ngokuprintwa kwe-sublimation inki ngokusisigxina iba yinxalenye yengubo. Oku kuthetha ukuba ngoshicilelo lwe-DTG unokufumanisa ukuba uyilo lwakho luya kunxiba, luqhekeke, luxobuke, okanye lukhuhle ngokuhamba kwexesha.
