Raws li peb txhua tus paub, qhov zoo ntawm kev luam ntawv yog cuam tshuam los ntawm ntau cov qhob, thiab cov kab nrib nrab yog qhov tseem ceeb tshaj plaws. Feem ntau, qhov teeb meem zoo thiab sau npe ntawm cov luam ntawv feem ntau yog vim li cas tsis tsim nyog hloov ntawm mesh nrug los yog ib txhia kev kho kom them rau qhov tsis xis nyob ntawm lub mesh.
Lub web nrug, uas yog qhov kev ncua deb ntawm qhov luam tawm ntawm lub npo ntawm lub npo thiab cov nplais ntawm lub substrate. Hauv kev luam ntawv, kom thiaj li tiv thaiv qhov kev sib tw ntawm sab hauv lub substrate, ib qho chaw nrug yuav tsum tau ceev cia ntawm lub vijtsam luam ntawv thiab cov ntawv lo. Thaum cov vijtsam glued rau lub substrate, nws yuav ua rau qhov kev luam zoo. Cov nyhuv ntawm txoj kev mesh yog kom ua tiav qhov teeb meem no, yog li ntawd lub vijtsam tsuas kov lub substrate thaum scraper scraped. Thaum cov txeej scraped scraped, qhov screen rebounds. Qhov tshuaj ntsuam thiab lub substrate yog instantly detached kom tsis txhob muaj qhov phenomenon ntawm dragging thiab smudging.
Tsis tas li ntawd, lub tswv yim ntawm "kev rov qab sab nrauv" yuav tsum raug to taub. Nyob rau hauv kev tshuaj ntsuam luam tawm, nws yog ze ze rau Mesh deb, tab sis txawv los ntawm Mesh deb.
"Rebound distance" txhais tau hais tias qhov nrug ntawm qhov screen rov qab qeeb qeeb tom qab khawb ntawv scraped. Nws tshwm sim thaum pib ntawm qhov chaw luam tawm thiab tshwm sim thaum lub sij hawm seem scrapering ntawm scraper. Nws xyuas kom meej tias qhov screen yuav thim rov qab sai sai thiab ua txhaum ntawm cov substrate. .
Lub dav mesh nrug nyob rau hauv kev tshuaj ntsuam luam tawm yog 9.5-12.7mm, tab sis nws yog ntau tsim nyog thiab ntau siv yog 1.5-3.0mm. Qhov chaw deb network tau coj ntau yam teeb meem rau kev luam ntawv zoo thiab kev cuv npe, yog li qhov kev qhia mesh yuav tsum yog me me li qhov ua tau. Thaum luam tawm ib co khoom uas muaj ntau dua, qhov tso cai ntawm cov duab deformation ncaj nraim txiav txim seb qhov loj ntawm lub mesh nrug. Hauv hluav taws xob cov khoom luam tawm, cov ntxaij ntawm cov ntxaij lim hlau tsis tshua muaj me me, li ntawm 0.1-0.2 hli.
Yog li ntawd, txawm nws tau sau cov duab los yog cov ntaub qhwv ntsej muag, qhov kev mesh nrug yog ib qho parameter uas tsim nyog muaj kev tshwj xeeb. Thaum cov mesh nrug tsis tsim nyog los sis tsis sib haum, nws yuav nqa cov khoom poob hauv kev luam thiab yuav tsum ua tib zoo tswj.
Muaj kev sib raug zoo nrog qhov chaw
Hauv ntau lub xim thiab plaub-xim vijtsam luam ntawv, xim sau npe yuav tsum tau zoo, thiab cov kab sib txawv ntawm txoj kab sib txawv plays lub luag haujlwm tseem ceeb. Hais lus tsis meej, nws tsis tuaj yeem ua qhov teeb meem thiab cov ntawv tseem ceeb ntawm qhov chaw mesh, uas yog tshwm sim los ntawm telescopic deformation ntawm qhov screen thaum lub sij hawm luam ntawv. Qhov loj dua lub mesh nrug, qhov ntau dua qhov cov ntshav siab thiab ntau dua qhov ncab ntawm qhov screen, uas ua rau ib tug qauv hloov rau ntawm substrate. Lub network nrug me me, uas tuaj yeem txhim kho qhov teeb meem no rau ib qhov twg. Yog li, thiaj li yuav txo tau cov duab ua haujlwm, nws yuav tsum xaiv mesh suab li tsawg tau. Rau ib co prints nrog dua kev sau npe, nws yog pom zoo tias mesh deb yuav 1.5 hli thiab qhov siab tshaj plaws yuav tsum tsis txhob tshaj 3mm.
Raws li lub mesh nrug nce, ntau teeb meem tshwm sim. Ua ntej tshaj plaws, kom paub meej tias qhov screen yog nyob rau hauv kev sib txuas nrog lub substrate thiab tus number case yog pauv, lub siab ntawm cov hniav yog inevitably ntau zog, thiab cov quab yuam ua ntawv thov rau ob hnub ntawm cov hniav yog ntau dua. Txheeb ze rau ntawm lub thav duab, qhov ntev ntawm cov hniav, qhov ntau mas no phenomenon. Nyob rau hauv no txoj kev, tsis tsuas yog cov degree ntawm deformation ntawm tus qauv yog nce, tab sis kuj tseem zoo print cuam tshuam.
Tsis tas li ntawd, qee lub sij hawm tus qauv luam tawm yog skewed thiab elongated, uas yog ib nrab vim teeb meem mesh, tab sis kuj mus rau txoj hauj lwm ntawm tus qauv, qhov ntev ntawm cov hniav, thiab cov kev taw qhia uas tus hniav khiav.
Nws yog ib qho tseem ceeb los tswj kom muaj kev sib txawv ntawm lub ntsej muag hauv kev luam ntawv. Yog tias lub vijtsam ncua ntawm lub vijtsam tsis muaj teebmeem nyob sab nraub qaum, sab laug, sab laug, thiab sab xis, cov duab nyob ntawm qhov chaw ua haujlwm yuav tsum yog. Hauv qhov no, qhov thib ob xim yuav tsis rau npe nrog thawj xim, tsis muaj teeb meem npaum li cas tus neeg tsav tsheb ua haujlwm. Obviously, yog tias cov xim ntau hauv cov ntawv luam tawm tsis tuaj yeem tso npe, tag nrho txoj hauj lwm yuav tsum yog khawb.
Nws yog tsim nyog hais tias nyob rau hluav taws xob hauv hluav taws xob, qee yam txawv txav tuaj yeem ua ntej them rov qab los ntawm xam thaum tus qauv tsis suav. Tsis tas li ntawd, qee tus lag luam tau ua cov khoom siv uas muaj peev xwm los daws cov teeb meem no.
Tseemceeb rau duab zoo
Mesh nrug chaw yog tsis haum. Thaum lub sij hawm luam ntawv, lub siab yuav tsum ntxiv lossis txo, uas yuav cuam tshuam rau qhov zoo ntawm kev luam ntawv, ua rau cov neeg pluag kev luam, plooj, npuas, txhom, poob poob, tsis muaj lub ntsiab txhais tsis zoo, thiab moiré. , tus qauv tsis tiav thiab li ntawd.
Qhov kev deb network tsis loj heev, thiab nws yuav ua lwm yam teeb meem. Piv txwv, tus kws kho mob yuav tsum ua kom siab ceev kom ceev kom lub vijtsam tuaj yeem kov lub substrate, tab sis ua ntej qhov screen yog sib txuas nrog lub substrate, tus cwj mem muab tso rau hauv qhov chaw luam tawm ntawm qhov screen. Yog tias qhov no yog qhov loj, nws yog ua txhua yam los ua Ib qho qauv ntawm ib qho chaw qias neeg los yog substrate. Kev nrawm tob tob ntau kuj tuaj yeem ua rau cov duab raug puas tsuaj, ua rau lub cev deformation lossis dot enlargement.
Qhov ntau dua ntawm qhov chaw siab, qhov ceev ceev ntawm qhov ceev ntawm qhov screen tom qab luam ntawv, tus number case yuav tsis puv tag mus rau lub substrate, uas yuav ua rau cov tsos ntawm moiré, tsis tiav cov qauv, cov duab kos, npuas, txhais pluag txhais, thiab lwm yam. Kev luam rickets.
Lwm qhov ua rau cov neeg pluag print zoo yog qhov tsis sib haum ntawm qhov kev tshuaj ntsuam thiab qhov me me mesh. Nyob rau hauv qhov no, qhov screen yuav wrinkle thaum lub sij hawm tus kws kho mob lub ntsej muag qhwv, ua cov kab txaij ntawm qhov teeb meem luam tawm, nws thiaj li ua rau cov duab liab qab thiab ghosting.
Txiav txim siab lub thickness thiab xim ntawm tus cwj mem kua adhesion
Cov cwj mem tsis sib xws ntawm cov cwj mem kua qaub yuav tshwm sim los ntawm cov nram qab no: (1) qhov tshuaj ntsuam thiab lub substrate tsis sib npaug; (2) lub mesh nrug, lub hau thiab qhov nro qhov ntsuas yog qhov txawv txav; (3) qhov screen spacing yog loj heev, ua rau cov hniav mus deform. Ib qho ntawm tej yam no yuav ua rau tsis muaj cwj mem tsis txaus muab tus kabmob, thiab qhov kawg sau tau sib txawv hauv cov xim.
Lub me me mesh nrug tuaj yeem txhim kho kev xyaw xim lo cim, thiab mesh nrug loj heev, uas nyhav ua rau lub cim tsis tseem ceeb, ua rau ob hnub ntawm scraper, tus number case adhesion yog ntau tsis sib txig.
Cuam tshuam cov qauv ntawm cov ntxhiab thiab cov thawv
Qhov screen, screen thiab scratching hli siv nyob rau hauv cov txheej txheem luam ntawv yog tag nrho cov ywj. Hauv txoj kev siv ntau dua, yog tias qhov quab yuam loj heev, lawv cov elasticity yuav qis qis lossis ploj. Thaum lub mesh nrug yog loj, tus number case squeezing siab yuav inevitably nce. Nyob rau hauv xws li tej yam kev mob, lub vev-xaij ntawm lub vijtsam thiab tus cwjpwm yuav raug qaug zog.
Hais txog kev ceev thiab kev siv zog
Yog hais tias lub mesh nrug yog loj dhau, lub zog yuav raug txo. Qhov no yog vim hais tias thaum lub sij hawm luam ntawv, tus kws kho mob lub qhov muag nyem qhov screen kom hu rau saum npoo ntawm lub substrate ua ntej tus number case yog yuam kom dhau los ntawm lub mesh mus rau lub substrate. Nyob rau hauv txoj kev no, lub siab ntawm tus nplaig yuav consumed thiab kis, uas zoo txo cov zus tau ceev ntau lawm. Hauv phau ntawv luam tawm, lub tshuab luam ntawv yuav tsum siv ntau yam quab yuam kom luam tau, uas yuav yog qhov tshwj xeeb tshaj tawm thiab qee zaum muaj kev ywj pheej.
Textile luam ntawv
Muaj ob peb lub ntsiab lus uas yuav tsum tau hais tshwj xeeb ntawm qhov kev ncua ntawm textile printing. Cov ntaub ntawv yog ib qho khoom ua tsis tshua zoo heev, yog li qhov me me yog qhov me me tshaj qhov ntawm lwm cov qauv duab.
Qhov zoo tshaj plaws mesh nrug yuav tsum yog 0.8-1.6mm. Txawm li cas los xij, qhov chaw tshwj xeeb yuav tsum yog raws li cov xwm txheej xws li tshuaj ntsuam nro, npo npo, thiab hom ntawv siv. Mesh nrug me me, thiab tus nqi ntawm tus cwj mem txuas nrog rau lub tshuab luam ntawv yuav tsum tau txo.
Vim tias textile luam ntawv tau siv ntau lub taub hau ntawm ntau lub chaw luam tawm, lub uniformity ntawm lub web spacing ntawm txhua lub chaw nres tsheb luam ntawv yog qhov tseem ceeb tshwj xeeb tshaj plaws kom muaj kev sau npe ntawm ib tug neeg xim thiab uniform xim laus ntawm tus number case. Tsis tas li ntawd, yog tias koj xav sau cov qauv ntawm ob peb lub ris tsho, qhov ntev ntawm lub mesh yuav tsum raug kho raws li qhov hnyav ntawm cov tsoos tsho.
Yuav ua li cas kom txo lub mesh deb
Yuav kom txo txoj kev nrug mesh, thawj lub teeb yuav tsum nce lub nro ntawm qhov screen. Lub vijtsam npo yog qhov siab, uas tuaj yeem txo qhov kev ncua kev sib raug zoo thiab ua rau kom zuj zus ntxiv. Txawm li cas los xij, qhov kev nce qib hauv qhov kev nrhav siab tsuas yog siv los ntawm lwm yam xwb, tab sis qhov tsawg, nws yuav tsum ua kom tau raws li qhov xav tau ntawm kev luam ntawv.
Nws yuav tsum nco ntsoov tias qhov loj qhov screen, qhov tsawg dua qhov kev tshuaj ntsuam yog mus cuag siab nrawm. Yog li, thaum xaiv qhov kev tshuaj ntsuam ntawm qhov kev tshuaj ntsuam, nws yog qhov tsim nyog yuav tau xam ob qhov luaj li cas ntawm qhov screen thiab qhov nro ntawm qhov screen. Feem ntau, qhov nro yuav tsum nyob rau hauv qhov ntau ntawm 18-25 N / cm, yog li ntawd nws tsis yog preferable tsuas yog nce lub nro ntawm qhov screen. Ntxiv mus, qhov nro ntawm txhua qhov screen hauv txhua qhov ntxig ntxaug yuav tsum zoo ib yam. Qhov tseeb, lub ntsiab lus ntawm lub vijtsam tsho yog qhov tseem ceeb tshaj qhov nro nws tus kheej, yog li ntawd tsis yog qhov tsuas yog qhov sib tw ntawm cov xim thiab xim, tabsis qhov tseem ceeb ntawm qhov kev mob siab yog qhov tseem ceeb.
Ntxiv nrog rau qhov nro ntawm qhov screen, lwm nco ntsoov yog tus number case. Lub khob ntawm tus cwj pwm xiam hoob khawm muaj feem xyuam rau rheology ntawm tus cwj pwm, cov lus muaj pes tsawg tus ntawm tus cwj mem, qhov luaj li cas ntawm cov zauv ntawm cov zauv, qhov siab nro thiab lub sij hawm cia. Yog hais tias qhov xauv npo ntawm qhov loj, nws muaj peev xwm ntxiv ib co additives rau tus number case los yog siv lwm cov phev. Nyob rau hauv qhov chaw ntawm tib nro ntawm qhov screen, txo viscosity ntawm tus number case yuav ua rau lub mesh deb dua.
Cov kev qhia ntawm kev tshuaj ntsuam kuj yog ib yam tseem ceeb uas cuam tshuam txog kev hloov qis dua. Qhov me me hauv cheeb tsam ntawm lub vijtsam (xws li, lub mesh muaj ib txoj kab nruab nrab ntawm 27-31 μm), yuav tsum tau tev tawm qis dua ntawm tus lej thiab qhov substrate. Lub zog me me yuav tsum, qhov me me ntawm qhov chaw mesh.
Qhov saum npoo ntawm lub substrate kuj yog ib qho tseem ceeb uas cuam tshuam kev hloov mis thiab muab luam tawm. Qhov kev tshuaj ntsuam thiab tus cwj pwm kua xau npau npau yog qhov yooj yim cais. Qhov nplaim ntawm lub textile muaj lub peev xwm nqus tau, yog li qhov screen yog yooj yim sib cais los ntawm lub substrate, uas yog vim li cas qhov deb ntawm textile luam ntawv yog me dua li ntawm lwm cov duab. Qhov nro ntawm qhov chaw ntawm lub substrate cuam tshuam lub zog ntawm tus number case, ces nws muaj ib yam cawv rau tom qab luam ntawv.
Lwm yam tseem ceeb uas pom tias qhov kev ncua ntawm lub mesh yog cov npo me me, qhov ntev ntawm qhov ntev (ntsuas ntawm qhov kev tshuaj ntsuam), luam qhov loj me me (raws li qhov ntsuas), thiab hom qauv (muaj qauv thiab tsis muaj qauv uas xav tau qhov kev sib tw loj dua).
Qee yam ntawm cov no yuav raug pauv, tab sis lwm tus neeg tsis tuaj yeem hloov. Txhua qhov luam tawm nws muaj nws cov kev cai luam tawm, thiab peb yuav tsum to taub tias nws yog ib qho tseem ceeb uas yuav tsum kho qhov kev mesh nyob rau hauv ntau yam kev luam ntawv. Los ntawm kev txhim kho cov txheej txheem khiav hauj lwm thiab nrhiav cov tshiab cov khoom siv, yuav tsum ua kom paub tias yav dhau los thiab qhov commissioning yuav ua tiav tiav sai li sai tau.
Txoj kev ntsuas qhov kev ncua deb ntawm kab sib chaws
Nws muaj ob txoj kev los tswj thiab txiav txim siab txog qhov chaw mesh. Muaj ntau lub tshuab luam ntawv tsis zoo thiab qee cov tshuab luam ntawv kev luam ntawv muaj cov kev sib txuas sib txuas network. Qhov teeb meem yog tias feem ntau ntawm lawv tsuas yog tau muab ntxais dua. Tsuas yog ob peb yam khoom zoo kawg nkaus yog nruab nrog ib lub xov tooj uas tshwm sim, uas tuaj yeem tso saib cov kab nrib nrig. Yog li, feem ntau, nws yog ntawm tus neeg teb xov tooj kom kho.
Hauv kev xyaum, tus neeg teb xov tooj tau tshawb txog qee txoj hau kev thiab kev paub txog kev ntsuas thiab kev tswj lub qhov chaw mesh. Qhov yoojyim tshaj yog kom muab lub khob rau ntawm plaub lub kaum pob ntawm lub rooj luam ntawv nrog lub tshuab ntxhua khaub ncaws thiab tom qab ntawd tso lub vijtsam rau plaub. Nyob rau lub rhawv, nyias muaj nyias cov pa roj carbon monoxide yog siv rau kev sib txawv mesh spacings. Rau qhov kawg, nws tseem ua tau kom muaj qee qhov nyias thiab nyias nkev khoom kom tau raws li cov kev xav tau ntawm ntau yam mesh ncua kev, thiab kom paub meej tias qhov tseeb ntawm daim phiaj sib tsoo. Ib qho yooj yim dua yog ntsuas qhov nrug ntawm qhov hauv qab ntawm qhov screen rau lub rooj los yog lub tshuab nqus tsev uas siv tus pas ntsuas los yog cov khoom tawg.
Yog tias koj muaj ib qhov xovxwm nrog tus xov tooj uas koj nyeem tau, koj tuaj yeem nyeem cov nuj nqis ncaj qha, uas yog qhov tseeb tshaj plaws. Txawm li cas los xij, raws li tau hais los saum no, feem ntau, yuav tsum tau kho kom zoo. Yog hais tias lub network sib nrug tsis raug kho, qhov teebmeem loj dua. Qhov kawg xaiv rau kev tshuaj ntsuam cov tshuab luam ntawv siv yog siv cov khoom siv sib cav sib thooj. Muab lub ntsuas ntsuas ntawm qhov npo ntawm lub vijtsam, xoom qhov rooj, thiab tom qab ntawd maj mam nias qeeb kom txog thaum lub vijtsam nphav npoo ntawm cov ntawv lo. Tus nqi ntsuas hauv qhov ntsuas yog rho tawm ntawm qhov tuab ntawm qhov screen. Qhov txawv yog qhov deb ntawm lub network ntawm no. Ntsuas nrog ib daim phiaj sib tsoo, ntev li ntev tau, qhov tseeb yog qhov tseeb. Nrog rau hom kev ntsuas ntawm no, nws yuav tsum pib dua ua ntej txhua qhov kev ntsuas, thiab tib lub sij hawm, nws muaj qee lub zog ntawm qhov screen. Yog li ntawd, nyob rau hauv qhov kev nkag siab, nws tsis yog yooj yim heev los siv xws li ib lub ntsuas ntsuas ntawm ib co printing presses. Txawm li cas los xij, qhov kev lag luam luam ntawv tsuas muaj ib qho kev ntsuas ntsuas.
Nws tau tshaj tawm tias US Screen Printing Technology Foundation (SYTF) tau tsis ntev los no tau qhia ntau qhov kev sib txig nyob hauv kev ntsuas, qhov ntsuas hluav taws xob, uas tuaj yeem ntes qhov chaw ntawm qhov screen sai thiab ntau dua. Qhov ntsuas ntsuas yog yooj yim los siv thiab tuaj yeem tso saib tus nqi ntawm kev lag luam txhua lub sijhawm, yog li ntawd tus neeg teb xov tooj tuaj yeem ua kom tiav cov kev debugging ua haujlwm ntawm lub siab.
