Nyob rau xyoo 1990, Zhang Yeping Printing Tshuab muaj ib qho kev sib txuas ntawm ob leeg - thiab ob tog sib luag lub tshuab luam ntawv nrog ib leeg-xim, ob-xim sib txawv-tig txoj kab hlau. Nws dheev los ua thawj plaub thiab plaub kawg ntawm 4 + 4. Kua tshuab tshuab muaj xim. Tab sis qhov no txhais tsis tau tias qhov no muaj yim-xim tshuab yog nyob rau hauv txoj kev, muaj ntau ntau lub tshuab luam ntawv, hais kom zoo li Zhangye yim-xim tshuab, thiab qhov kev faib ua feem ntawm kev tawm yog 60%. Nyob rau hauv kev lag luam luam tawm ob txhais tes los ntawm 1996 txog 2000, qhov no yim-xim tshuab tshuab cav muag kom luag yuav luag ib nrab ntawm lub tshuab, thiab cov cav tov tsuas yog kwv yees li 20% ntawm kev ua lag luam. Vim li cas thiaj muaj coob tus neeg tsis tuaj yeem ua haujlwm rau nws? Qhov teeb meem loj yog tias tus number case nyob rau ntawm thawj nto tau zoo thiab qhuav, thiab daim ntawv xa mus rau sab nraum qab, thiab sab nraud ntawm lub thwj yog khawb rau cov ntawv pov tseg. Txawm tias nyob hauv lub tshuab nqus tsev, lub tshuab sab nraub qaum sab nraub qaum los yog Cov ntaub ntawv qub uas tau qhuav thiab khov lawm sau tam sim no tseem tseem kho los yog tsuas yog cov ntawv luam ua kua. Thaum txoj kev txhuam liab tawm yog attracted, nws yuav ua rau khawb los yog khawm tus cwj mem los ntawm lub qub nres. Nyob rau ntawm daim ntawv luam tawm tshiab, cov khib nyiab phem no yog tshuab ob tog, uas nyuaj rau cov neeg siv tau txais. Yog li ntawd, qhov kev tsim kho ntawm ob npaug kom muaj xim muaj xim kaum xim thiab kaum xim tshuab yog ib zaug hindered, tab sis hnub no DRUPA 12 Düsseldorf Printing Machinery Exhibition, khoom, printing presses thiab khoom factories tau npaj ib co anti-stick thiab anti- fouling txoj kev.
A. Cov ntawv qhia txog kev tiv thaiv thiab cov txheej txheem los tiv thaiv, tseem siv cov tshuab ua ob npaug rau, xws li cov kab tangential lossis kab dabtsi ntawm phau ntawv qhov ncauj, rau qee tus choj siab thiab cov kev taw qhia kom dhau daim ntawv, txawm tias kev sib txhuam, yav tom ntej Nws tuaj yeem muab zais thaum khi, thiab nws zoo dua rau phau ntawv luam tawm. Tam sim no nws siv cua tshuab daim ntawv qhia, yog li nws yog qhov yooj yim thiab siv tau yog tias nws yog cua tshuab los ntawm cov cua uas tsis muaj kev sib tsoo tsis muaj kev sib tsoo. Raws li rau cov tub ntxhais ntawm qhov siab, qhov siab ntawm lub cev tawm ntawm sab nrauv yog muab nrog lub plhaub chrome-plated los tiv thaiv lub tsho, tab sis cov nyhuv tsis zoo. Tom qab, lub xuab zeb txheej txheem ntxhib ntxhib ntxhib los ua lub ntsej muag muaj qhov zoo dua, tab sis tsis pub siv ntev ntev. Vim tias cov xoom kua quav ib txwm khib nyiab, nws yuav tsum ceev nrawm txij li ib lub sijhawm, thiab tsuas muaj ib qho taw qhia xwb tsis txhob xuas tus number case ntev. Raws li lub tshuab nqus tsev rau ntawm daim ntawv tso tawm tais, nws tsuas yog ib qho ntawm txoj kev hloov pauv qhov nqus ntawm qhov 5mm wide thiab me me adsorption tais kom qhov chaw ntws tawm hauv qee yam txwv. Kev txhim kho ntawm cov txheej txheem ntawm cov khoom siv ua ke thiab cov tsho tsis tau ua ntau txoj kev kawm.
B. Siv tus cwj pwm uas muaj kab mob siab ceev ceev uas muaj tus cwj pwm sai ntawm tus cwj pwm kom tsis txhob ua kom khaus, qhov no yog qhov chaw uas cov tshuab fais fab siv los ua kev xav tsis zoo. Nws yog tseeb hais tias txawv teb chaws yog nyob rau hauv plaub thiab anti-plaub-xim tshuab, uas yuav ua tau sai sai thiab nquag, tab sis yuav nyob rau hauv Suav teb. Qhov tshuab tig-hom plaub-xim tsuas yog pom tias cov stains hauv cov luam ntawv ua rau nws nyuaj ua haujlwm. Tom qab ntawd, kuv tau mus ncig txawv tebchaw mus yuav tus cwj mem tshwj xeeb rau txoj kev sib tw ob tog. Yog li ntawd, cov nyhuv tau zoo dua thiab yuav luag luam tawm ntawm ob tog. Txawm hais tias muaj me ntsis ntawm pes, Tab sis qhov teeb meem no yuav tsum ignored. Thawj tus lej zuaj Hoobkas tau pom tias muaj kua xoo heev-tawv-co-denatured. Dab tsi yog shaken? Ntawd yog, thaum tus number case yog nyob so, lub polymer tsim cov qauv hauv lub network thiab daim tawv nqaij tsis adhered rau tus number case nyob ntawm txheej txheej. Ntawm qhov tsis sib haum, tsuav yog muaj qee thiab tuav, tus cwj mem rov los rau nws cov dej fluidity, thiab thaum nws raug shaken thiab adhered kom nres, Raws li qhov teeb meem, tus cwj mem xiav yuav tam sim ntawd tsim ib lub qauv mesh-xws li molecular structure uas yog npaj rau ziab . Yog hais tias qhov kev sib tw ua ntej yuav siv rau hauv lub tshuab ua ntej lub taub hau thiab muab tso rau hauv lub tsheb cement ua ntej-tsheb, txhua tus muaj peev xwm ua tau meej heev. Paub hais tias lub sam roj sib tsoo ntawm lub tsheb ciav hlau yuav tsum nco ntsoov kom tig mus rau hauv ib qho kev taw qhia, thiab yog hais tias txhua tus neeg tsis tig rau lub cement cia tank, txhua tus paub tias qhov kawg yuav phem heev, vim hais tias cov xis mas tsis txav mus rau hauv tsheb rau ib nrab ib teev. Nws yuav maj mam ua kom zoo. Tom qab peb lossis plaub teev, txawm hais tias nws tau tig rov qab los, tus cement yuav tsis tuaj tawm dua, vim hais tias cov xis mas tau zoo nyob rau hauv lub pob zeb cylinder ntawm lub tsheb! Cov luam ntawv yog ib cov cim tshwj xeeb uas muab ob npaug rau sab saud uas siv cov kev tuav pov hwm kom cov tshuab luam ntawv yoojyim thiab muab tsau. Vim hais tias nws tau raug mob nyhav thiab tsis tawv nqaij ntawm lub tshuab luam ntawv, ib zaug luam tawm ntawm daim ntaub ntawv, ib qho chaw luam tawm txheej duab zoo li qub, tsuav nws nyob hauv ntej. Tom qab plaub los sis tsib lub xim luam tawm, ntau tshaj li ib nrab ntawm daim ntawv pub ntawm qhov nruab nrab ntawm peb daim ntawv cog lus qis tau txaus los tsim ib lub cev tsis xeb (ziab) phenomenon, txhais tau hais tias tus cwj mem tsis tag Tag Nrho hauv qab, tab sis number case nyob rau ntawm qhov chaw, thaum kov nrog tus ntiv tes, nws tsis nkag mus rau ntawm tus cwj ntub ntub los ua cov ntiv tes thiab cov cwj mem kua adheres rau ntiv tes ntiv tes. Qhov no hu ua tus ntom ntom ntawm qhov qhuav, txuam rau cov nplais deg ntawm lub nrob qaum. Cov duab tso tawm, hauv qab xim plaub-ceg ntawm cov ntawv tom qab, xws li taug kev hauv dej, nws yuav tsis tsim cov ntawv nplaum nplaum, thiab vim nws tsis rub tawm ob peb nplooj ntawv ntawm luam ntawv ntub kua xiav, nplaum Tsis txhob sau cov ntawv luam ntawm daim ntawv luam tawm tom qab luam tawm los ua cov xim. Ntxiv rau lub tsho tiv no, lub duav npog kuj tseem yog ib qho tseem ceeb tiv thaiv tsis ua haujlwm, tiam sis xim plaub lub xim ntawm ib lub teb chaws ib-kilogram ob muag muag nqi 1,500 Taiwan dollars, uas yog tsis txaus ua rau ntau printers. Vim li no, yuav muaj qee tus siv qee tus cwj pwm uas muaj kabmob sai sai los ua ob npaug rau ob sab tshuab luam ntawv, cov nyhuv tsis zoo ua luaj, tsis tshua zoo ua nrog nws, yog nyob rau hauv cov rooj sib txig txawv teb chaws, nws ntev siv siv high-shaken densification number case los txhawb cov kab mob thaum ntxov ua lub hauv paus loj.
C. yuam kev tua uas siv ib tug Hybrid number case. Yog tias koj siv tus cwj pwm UV-curable rau txhua qhov xim ntawm lub tshuab luam ntawv pem hauv ntej, thiab txhua lub luam ntawv muaj ib lub teeb UV, ces nws yog qhov zoo tshaj plaws ntxeev siab saum toj kawg nkaus, tus number case uas tau raug kiag li qhuav ntawm cov ntawv luam , tom qab Daim ntawv hloov, embossing, thiab txawm tus me nyuam ntawm cov ntawv luam tawm yuav tsis nplaum, qias neeg los yog khawb. Txawm li cas los xij, kev siv ntawm plaub UV yaj muaj nws cov hwj huam noj. Yog li no, qee cov case zauv hauv Nyiv koom tes nrog lub tshuab luam ntawv tshuab luam ntawv siv tus Hybrid number case, uas tau muab luam tawm tsis tas siv cov roj hmab tshwj xeeb rubber los yog daim pam. Dua, thaum lub plaub xim luam tawm, thaum lub tshuab luam yeeb tawm hauv nruab nrab, lub laub luam tawm ntawm tus cwj mem kua xyaw yog kho los ntawm ib txheej UV nta, kom rov qab luam ntawv tsis muaj kab mob, yog tib hom Number case thiab curing txoj kev kuj siv nyob rau hauv plaub lub xim ntawm kev xa ntawv tom qab, yog li tsis muaj rov qab luam los yog ua raws li ntawm lub rooj zaum. Yog vim li cas tsis siv UV number case los siv Hybrid number case, muaj ob lub hauv paus, UV number case ntau tshaj 5-6 lub sij hawm ntau tshaj tus qauv number case, Hybrid number case tsuas yog 50% zoo dua qub tus cwj mem nyob hauv Nyiv, tus nqi yog tsawg, tus thib ob yog cov ntawv xov tooj ntawm Hybrid number case, Number case Chaav thiab cov pam yuav siv tau ntev li thaum lawv siv lub xov tooj dav dav, thaum UV phom yuav tsum siv UV-resistant luam daim hlau thiab rubber rollers thiab rubber clips. Txawm li cas los xij, Hybird number case ua rau kev ua tiag tiag thaum lub sij hawm luam tawm-mus-tua tsis ntev. Cov nplaim yog ntxhib thiab npub, uas yog, thaum tus npuas daj uas luam tawm rau sab xub thawj, nws nkag mus rau UV teeb kom zoo, thiab tus cwj mem tawm ntawm daim pam pua chaw. Thaum cov nyhuv tawm, cov nplaim ntawm qhov chaw xws li maltose yog tsis sib txig. Yog hais tias qhov saum npoo yog "ntog" rau 5-6 vib nas this, qhov saum npoo yog du thiab du, tab sis tom qab lub plaub xim yog nias, tus menyuam tau kho kom ceev li ntawm 12,000 nplooj ntawv ib xuab moos. 200 nas this, ces tsuas yog 0.6 ~ 0.7 vib nas this yuav tsum irradiated thiab kho tam sim ntawd, thiab tsis muaj cov cwj pwm txaus kom txo lub sij hawm gloss, uas yog tsis heev. Yog li, Hybrid number case zoo hauv kev ziab, hauv nruab nrab thiab hauv nraub qaum los tiv thaiv ua kom tsis txhob so thiab staining, tab sis nws tseem yog ib txoj kev luam tawm nrog lub matte tiav.
D. Siv cov hluav taws xob uas tsis muaj hluav taws xob UV LED, H UV lossis LE UV yaj, ib zaug xwb kev kho thiab tom qab ntawd ob sab ntawm luam tawm, txoj kev no thiab luam ntawv nrog UV yaj, siv Hybrid number case rau ob npaug rau ob sab phaj, tib lub curing sab nkag mus rau sab nraum qab ntawv, thiab tom qab sab nraum qab ntawv luam tawm, nws kuj ua tau ib qho tshuaj tua hluav taws xob. Qhov sib txawv ntawm qhov tsuas yog qhov UV teeb uas siv rau hauv UV number case los yog Hybrid number case yog siab zog UV teeb, yog yim qhov xim tshuab siv 80Kw ntawm lub zog qhov hluav taws xob, ces lub UV teeb siv nyob rau hauv lub tshuab ob tog yuav tsum siv 100Kw ntawm teeb meem siv hluav taws xob. Lub hauv paus loj yog qhov UV teeb uas tsim los ntawm UV teeb yog tsuas yog 28 ~ 30%, thiab lwm tus pom pom teeb uas tsis muaj kev cuam tshuam rau UV number case curing. Los yog ib feem loj yog IR IR, uas peb tsis xav tau, tso cai rau 51% ntawm qhov ratio, uas yog qhov teeb meem heev, vim tias IR tsis tsuas yog nce qhov kub ntawm qhov khoom tawm los ntawm 15 ~ 25? tseem ua luam ntawv. Lub tshuab thiab qhov chaw nyob yog kub heev, yog li nws yuav siv ntau lub zog cua txias coj mus rau IR infrared kub generated los ntawm lub teeb, yog li UV curing number case siv tau UV chemical lub zog los ua tus UV number case tsawg tshaj li ib nrab . Tshuab Start-up, thiab ua rau UV roj teeb duab-rhiab monomer rau polymer txuas tua, cov nyhuv no tsis tas kom lub cua sov ci ntsa iab, tab sis cov hluav taws xob hluav taws xob kuj muaj lub tswv yim los ua kom muaj qhov kub thiab nce cov tshuaj lom neeg , tab sis feem ntau yog qaug zog. Lub cim tshiab ntawm high-spectrum ultraviolet teeb qhov chaw hu ua H-UV los ntawm UV LED los yog Komori xovxwm, thiab LE (Tsawg Zog) siv Heidelberg. Ntau tus neeg xav tias UV LED los yog H UV thiab LE UV yog lub zog tshiab kuj muaj zog. Qhov tseeb, qhov tseeb yog qhov tseeb. Nws tsuas tsiv lub spectrum ntawm UV lub teeb mus ze ze ultraviolet lub teeb, thiab UV B ntawm lub zog loj dua. UV C tsis tshwm sim lossis txo qis. Zoo li UV LEDs, Crystal lub teeb emission tshwm sim nyob rau hauv ib zaug spectral nkaus xwb. Los ntawm kev sib txawv spectrums li 365nm, 375nm thiab 385nm, tsuas yog ib lub spectrum ntawm lub teeb tawm. Yog li ntawd, UV LED nws tus kheej tau tawm ntawm lub teeb thiab cua sov, thiab tsis xav tau dej txias rau saum cua. Nws yog qhov txaus. Siv dej kom txias, nws tsuas xav tau lub peev xwm me me xwb. Txawm li cas los, yog tias UV spectrum yog siv los kho tus cwj mem piv txwv, yog hais tias cov duab thaij duab zoo nkauj heev nyob ze ze-400nm violet, tus cwj mem nws tus kheej kuj tsis tshua muaj siab npaum li cas, thiab nws yuav tsis kho txhua. Ntawd yog, yog tias koj siv hom UV number case printing, thiab siv UV LED lub teeb ci los kho, nws yuav tsis muaj cov nyhuv nyhuv. Ua kom lub kaum lub sij hawm ntawm lub teeb lub zog tseem tsis txaus kom kho, vim hais tias tus number case yog rhiab heev 365 ~ 385nm, ces UV LED number case tsis yog tsuas yog rhiab, tab sis lub spectrum sensation yuav tsum sib phim rau high spectrum of UV LED, ib yam li lub xauv yuav tsum muaj ib qho tseem ceeb rau kev ua si, txwv tsis pub nws yuav tsis zoo. UV LED muaj sij hawm zoo los siv xim 4 + 4 ob tog tig ntsia tshuab es tsis txhob siv lub tshuab xoom xoom ob tog sib tw, thiab nws yog ib qho uas huv thiab zoo, thiab tsis muaj qhov cim tseg ntawm cov khoom qub. Nws yog qhov zoo tagnrho. UV LED muaj txoj haujlwm ntev ua haujlwm ntev txog 15,000 rau 20,000 teev. Tsis zoo li zoo tib yam UV yaj, lossis hluav taws xob ua muaj roj hluav taws xob nrog H UV thiab UV teeb, nws muaj lub neej ntawm 1,000 mus rau 1,500 teev thiab yuav tsum tau taws. Thiaj li yuav teb rau cov luam ntawv nrog khau raj. H UV txiav tawm UV C hauv qab 290nm, thiab tseem tshuav ib nrab ntawm UV C hauv 320nm, feem ntau tshwm sim nyob ze ze-ultraviolet light spectrum ntawm UV Ib 360 ~ 400nm, ces nws yuav tsum zoo xws li LE UV, thiab H UV number case Lub sensitized spectrum tsis xav tau zoo li UV LEDs, nws tuaj yeem nyob rau ntawm 360 ~ 400nm, thiab qee qhov IR tshwm sim hauv H UV teeb. Nws xav tau dej txias thiab cua txias khoom, ntau lub tshuab luam ntawv tshuab hauv lub ntiaj teb xws li Ryobi Mitsubishi Heavy Industries, tsom ntawm UV LED tua, KBA zoo li yuav tsum khaws cia, vim hais tias lub zog ntawm UV LED tsuas yog 20 ~ 25% ntawm lub zog ntawm dog dig UV yaj, uas txuag zog thiab txo qhov tshwm sim ntawm cov hneev taw tsis muaj ozone. UV LED lub teeb pom kev zoo thiab cov cua txias yog cov compact heev, thiab yuav luag tsis muaj lub teeb xau los ntawm tib neeg qhov muag. H UV zog noj yog 30% ntawm lub teeb UV. Nws tsis tas yuav muab cov hmoov tsuag rau ntawm daim ntawv txais lub rooj ntawm lub tshuab luam ntawv, uas yog, nws tuaj yeem ua tiav los ntawm origami, uas zoo heev rau kev txhim kho tus txheej txheem luam ntawv. Ntxiv mus, tsis hais txog ntawm UV LED luam, H UV, LE UV, qhov kub ntawm daim ntawv no tsis sawv ntawm tag nrho los sis tsuas yog nce me ntsis, yog li ntxiv rau qhov teeb meem ntawm qhov ntxhib ntawm daim ntawv luam tawm uas yog kho los ntawm kev luam ntawv, lub zog txuag UV teeb yuav tsum tau kho dua. Cov kaus noom ntsej muag nquag muaj peev xwm ua haujlwm.
E. Cov dej raws li ob txoj hlua khiab ob txoj hlua khiab ob lub hau, uas tau tsim xyoo no hauv DRUPA 12 KBA lub rooj nthuav rooj, uas yog, lub tshuab hluav taws xob khiav ceev, yog tias tus cwj mem yuav tsum kho los ntawm UV lossis UV LED teeb, cov ntawv luam tawm yuav yog qhov zoo tshaj. Feem ntau, cov ntawv luam tawm hauv qab ntawm 10,000 nplooj ntawv ib teev twg yuav yog OK. Rau 12,000 nplooj ntawv ib xuab moos, nws nyob ntawm lub thickness ntawm lub luam ntawv number case, tus number case txheej yog tuab heev, qhov kev xav tau siab dhau, los yog qhov nkag mus tsis txaus.
