Dab tsi yog qhov zoo ntawm kev siv UV inks es tsis txhob txwm cov raug rho tawm haujlwm-ceramic cov ntawv?
Fired-ceramic xim ua ib feem ntawm lub iav mus tas li. Iav ntxhov ntxhuav nrog cov xim muaj xim tsis tuaj yeem siv rau hauv cov xim flint iav, thiab yuav tsum yog "down-cycled" rau hauv cov xim iav. UV phom tsis paug cov hnyuv ntxig thiab tuaj yeem hloov txav mus rau hauv cov nplaim hluavtaws.
Ntau lub npias hom siv UV-curable inks vim hais tias cov chiv thawj tiv thaiv dej thiab txeej.
Tsis tas li ntawd, UV hauv phom yuav tsum tsis muaj zog. Cov kaus mom los yog cov iav fais fab yuav tsum raug rho tawm hauv cov kub-kub kub kom txog li 1,200 F txog li 30 min. Nyob rau hauv kev raug mob siab siv UV lub teeb, UV-raug lub plhaw raug kho hauv ib feem ntawm ib pliag.
UV inks thiab coatings kuj yog ntau dua hauv tsev. Tshwj xeeb, UV phom muaj tsawg los tsis muaj cov organic compounds sib xws (VOCs). Kev txhawj xeeb hnyav hlau pigments yog txav ntawm kev ua lag luam los ntawm tej daim ntawv sau rau cov kab mob UV-curable. Kaj ci liab, yellows, thiab zaub ntsuab yog poj ua yawm ua rau hnyav hlau pigments. Nrog UV inks, cov xim thiab ntau ntau tau yooj yim tsim nrog cov organic pigments. Cov kaus mom thiab coatings kuj tseem siv tau rau cov kab polyethylene terephthalate (PET los yog polyester) uas feem ntau siv rau dej qab zib thiab lwm yam dej haus. Thiab UV cov txheej txheem siv tsawg tus cwj mem los luam cov dluab nrog zoo sau txhais vim nws ntiav cov ntxaij vab tshaus muaj finer mesh suav.
Lub raj mis zoo li cas?
UV-curable inks thiab coatings tuaj yeem siv tau thiab kho nrog ntau txoj kev. Qhov tshwm sim yog ntau yam ntawm zoo nkauj zoo nkaus li. Vijtsam luam tawm yog ib txoj kev uas cov iav yog npaj rau kho kom zoo nkauj nrog nplaim thiab ntxuav. Lub hwj fwj tom qab tau kuaj thiab tus cwj mem muab ntxig rau hauv UV teeb. Lub raj mis tiav lawm muaj kev ntxhib los mos rau cov cheeb tsam uas qhov screen tuaj yeem mus txog lub raj mis.
Txoj kev siv electrostatic yog ib qho txheej txheem daim ntawv thov thiab nws nyiam heev vim tias iav yog ib qho insulator. Ntawm no, tus number case yog ncaj qha mus rau hauv lub raj mis, thiab tom qab ntawd lub tsho kho tau sai sai los ntawm UV teeb ntawm lub teeb hluav taws xob. Electrostatic txau ntau dua li cov tshuaj txau thiab tshuaj luam tawm vim nws coats rau sab nraum qab ntawm lub raj mis thiab sab pem hauv ntej nrog tsuas yog ib lub taub hau. Tag nrho lub raj mis yuav tsum tau coated, los yog cov di ncauj (tag) tuaj yeem tawm tsis pom kev. Txoj kev no yog ib tus neeg sib tw rau cov xim flint iav vim tias nws cov ris tsho hnav tsho zoo nkauj nrog rau txhua yam xim. Kuj tsis paub meej textures tseem tau nrog UV-raug pluaj coatings.
Cov inks lawv tus kheej tsim zoo nkaus li. Cov pob tshab los yog cov xim opaque tuaj yeem yuav muaj ntaub ntawv los tsim cov teebmeem tshwj xeeb uas yuav tsis tau raug rho tawm haujlwm-ceramic kho kom zoo nkauj. Piv txwv ntawm cov teebmeem tshwj xeeb no muaj xws li fluorescent (hnub ci), phosphorescent (glow in the dark), metallic, pearlescent, thermochromic (hloov xim thaum kub lossis txias), photochromic (hloov xim hauv tshav ntuj), glitter, ntxhiab, prismatic, los yog ntxeev / ntxig xim xim ua haujlwm (xim hloov nrog lub kaum sab xis pom).
Dab tsi tshiab txog technology?
Txoj kev mus thov thiab kho UV phua ntwm muaj peev xwm tsim tau lub raj mis thiab cov kev cai textures.
Cov dej hauv tiv thaiv dej hauv plastics, raws li pom ntawm cov zawv plaub hau, tau muaj nyob rau ntau xyoo. Cov kev kho tshiab tsis ntev los no hauv cov tshuab ua hluav taws xob ua rau dej tsis muaj zog thiab tsim rau cov iav fwj. Ua ntej cov kev kho tshiab no, UV phev rau cov iav tsis muaj cov ntiv taw xws li daim ntim kabmob, kev thev taus, thiab tsis tuaj yeem ua dej thiab dej khov uas yog qhov teeb meem nrog cov ntawv lo.
Tam sim no, UV-curable number case thiab cov txheej tshuab tsim cov khoom ci zoo nkauj uas yuav tiv thaiv tau cov kab mob ntawm cov kab khiav dej khov siab, nrog dej, dej khov, tu tshuaj, cov kuab tshuaj, thiab cov khoom siv. Piv txwv li, npias npog zoo nkauj nrog UV-curable number case tam sim no muaj peev xwm ciaj sia tuaj yeem sau kab thiab nyob rau hauv lub raj mis thaum muab tso rau hauv ib qho chaw hauv dej khov nrog lwm cov fwj, cov kaus poom, thiab dej los ntawm yaj cov dej khov.
Dab tsi ua ntej, tus txheej txheem lossis qhov phom sij?
Cov txheej txheem polymer tuaj ua ntej, tom qab ntawd cov phais thiab coatings raug tsim los ntawm theem pib. Cov qauv thiab raw cov ntaub ntawv raug muab kho kom zoo dua thaum kev kho thiab tuav cov cuab yeej tsim thiab tsim.
Cov kev lag luam siv UV ua haujlwm li cas?
Muaj ntau cov khoom siv tes ua npias, dej caw, thiab dab fwj paj zoo nkauj nrog UV-curable inks. Peb tau ua hauj lwm nrog ntau lub koom haum (breweries, wineries, distilleries) nyob rau hauv cov fwj uas muaj nyob hauv cov khw muag khoom muag. Cov npauj npaug loj tshaj plaws yog cov yuav siv cov ntaub nplaum los yog cov ntaub ntawv tso ncaj ncaj vim tias ceev ceev thiab ntau npaum li cas, tab sis cov kev kho kom zoo nkauj no yog rau cov neeg xav tau qhov siab tshaj los yog kev cai tshwj xeeb rau lawv lub hwj.
Dab tsi yog cov khoom tseem ceeb uas yuav tsum tau xav txog yog thaum xaiv tus cwj mem?
Cov kaus poom nrog UV-cured inks raug tshuaj ntsuam rau kev rub tawm thiab lwm txoj kab simulations. Piv txwv ntawm kab simulations muaj xws li 1-hr kub-da dej ntawm 180 ° F thiab txav mus rau hauv cov raj ntim rau 6 min ntawm kev ceev.
Cov phev tshuaj ntsuab thiab daim kab xev yuav tsum tsim kom zoo zoo rau iav thiab tus tsiaj. Cov tshuaj reim yuav siv tau rau hauv hluav taws xob tua kab mob UV thiab electron beam (EB). Rau UV curing, cov neeg siv cov khoom siv tsawg-migrants tuaj yeem siv tau rau cov txheej txheem tua kab tsis zoo rau organoleptic (saj thiab tsw) ntawm cov khoom noj thiab dej haus hauv cov hwj. Cov phom yuav tsum tsis muaj cov kuab tshuaj los yog VOCs, hnyav hlau, lossis Bisphenol-A (BPA).
Yuav ua li cas cov fwj nrog cov phais plab hauv?
Cov iav fwj txhua lub sij hawm rov ua dua, thiab lub zog siv qis nrog cov feem pua ntawm cov ntxhiab loj hauv qhov sib tov nrog cov iav tshiab. UV inks hlawv tawm thaum txheej txheem ubno, yog li ntawd tag nrho cov iav rov qab mus rau nws cov xim qub, feem ntau cov flint iav.
Dab tsi yog yav tom ntej rau kev siv tshuab?
Lub tshuab tev tauj ib zaug rau cov neeg lag luam uas tsim cov txheej txheem. Hnub no, muaj kev lag luam ntawm cov cuab yeej thiab cov txheej txheem technology nrog rau cov hauv plhaus nkoos thiab coatings. Lub tshuab hluav taws xob yuav pib ua lag luam nyob hauv lwm cov chaw tsim khoom kom cov tuam txhab tuaj yeem muab ib qho kom zoo nkauj thiab ntim.
Dab tsi yog qhov nyuaj tshaj plaws hauv kev tsim technology?
Peb tau npaj los daws cov teeb meem hauv ntau qhov chaw, los ntawm kev tuav thiab kho cov iav, los kho qhov txheej txheem kev kho, kom tsim pigmented inks uas qhia muaj zog xim txawm ntawm lub hwj yas. Muaj cov teeb meem hauv qhov ntsuas qhov hnyav los yog txheej thickness, tsom cov txheej txheem ntau txog 400 fwj / feeb, thiab teeb meem xim kasfes uas tsim tau thaiv UV.
