● Khaub Ncaws
Hais txog, tshwj xeeb tshaj yog monochrome screen printing los yog peb-xim, plaub-xim tshuaj ntsuam luam hauv qab, kuv xav tias hnyav-based inks yuav ntev dhau los ua dhau lawm. Hauv ntej, cov kuab tshuaj sib xyaw ua hnyav yog qhov nyuaj rau kev siv mesh luam ntawv. Yog li, kuv yuav tsuas tham txog UV kua number case.
Hais txog tus cwj pwm ntawm lub cev thiab tshuaj ntawm tus cwj pwm, qhov tseem ceeb tshaj plaws yog tseem thixotropy ntawm tus cwj mem (qhov thixotropy yuav piav tom qab). Duav nrog thixotropy pluag yog yooj yim diffused (ua rau cov dluab tsaus nti, loj dua, thiab me sib txawv me ntsis). Cov thixotropy number case kom cov dots nyob rau hauv cov duab, tab sis nyob rau hauv txhua rooj plaub, cov no yog tshwm sim los ntawm tus number case ntawm ntws los ntawm qhov screen.
UV number case yog tiag tiag tsis qhuav ntawm qhov screen, ces tus dots fine ntawm qhov screen yuav ua tiav luam. Ntxiv mus, peb yuav tsum xav txog lub luag haujlwm ntawm qhov screen, zaj duab xis thiab kev daws teeb meem ntawm photoresist. Txawm li cas los xij, nws tsis muaj teeb meem ntau dua thiab siv ntau dua qhov siv hnyav ua kuab.
Ntawm qhov tod tes, qhov zoo ntawm daim duab yog muaj feem xyuam rau thixotropy ntawm tus cwj mem (tsis ncaj qha ntsig txog UV nws tus kheej) hauv kev tswj cov kev sib nrauj thiab qhov teeb meem ntawm qhov tsis zoo.
Peb yuav tsum paub hais tias lub thickness ntawm tus number case ntawm cov thixotropy UV number case yog 2 ~ 3μm thicker dua UV number case nrog cov neeg pluag thixotropy. Txawm hais tias lub tom kawg tsis muaj cov organic hnyav, tus number case diffus me ntsis hauv lub mesh vim qhov kev txiav txim hauv capillary luam thiab lub sijhawm maj mam ntawm cov luam thiab dhau los ntawm UV teeb. Yog li, thiaj li yuav nrhiav tau cov duab zoo dua thiab zoo li nyias muaj nyias li txheej tau, nws yuav tsum tau kom lub tuam txhab lag luam luam yuav tsum pom tus nqi ntawm tus neeg saib xyuas thixotropic kom muab ntxiv raws li hom kev tshuaj ntsuam uas siv rau lub mesh uas luam tawm. Nws yog ib qho tseem ceeb kom paub tias UV number case (UV, dej raws UV, tag nrho dej los yog hnyav ua raws li) yog qhov tseem ceeb, nyob ntawm cov hauv qab no, yog tsis muaj teeb meem tshwm sim, tshwj xeeb tshaj yog mesh luam ntawv.
★ thixotropic - lwm rheology, etc .;
★ xim zoo;
★ lub ntsiab lus ntawm cov xim, uas txiav txim siab qhov ceev ntawm cov xim xim;
★ luam tawm ntsiab lus lossis luam phiaj xwm;
★ Images to be copied;
★ hom ntaub ntawv luam tawm;
★ Tshuab hom;
★ luam ntawv ceev;
★ siv luam ntawv;
★ Txheeb ze sib luag;
★ impurity;
★ tiv thaiv hnub tiv thaiv;
★ ua rau lub cev thiab tshuaj (khoom xyaw);
★ daim npav xim (txias los yog kub);
★ Yog tias tsis siv UV number case, tus lej siv ib hom qia neeg qhuav.
Tshwj xeeb tshaj yog cov tshuab luam ntawv, xaiv tus number case system. Nws yog decisive, thiab nws yog ib qho tseem ceeb uas tswj qhov kev hloov no. Tab sis qee zaus, vim muaj kev txwv ntawm cov peev, cov cwj pwm, lub hom phiaj thiab hom kev luam cov khoom qub, feem ntau tsis tau xaiv tus cwj mem, thiab cov uas twb muaj lawm siv ntau zaus. Obviously, luam UV cov ntxaij vab tshaus nrog UV phev lossis dej raws UV hauv phom yooj yim dua, tab sis nws tsis txhais hais tias koj tuaj yeem luam tsis tau lawv. Ua ntej UV number case nyob rau hauv kev ua lag luam, thaum ntxov li xyoo 1968, kuv luam 150 thiab 175 seem / nti. Ntawm chav kawm, nws nyuaj heev vim hais tias cov nplua mesh tau qhuav ntawm qhov kev tshuaj ntsuam thiab qee cov tshuaj txhuam corrosive tau thov rau lub stencil. Cov ntawv thiab photoresist txheej ua rau puas tsuaj.
UV inks tsis qhuav ntawm cov ntxaij vab tshaus. Muaj qee qhov kev pab cuam los siv qee cov dej muaj kuab los yog "xam yus tus kheej" uas yog "self-solvent inks", tab sis tsis hais txog qhov muaj feem xyuam xim, qhov tseem ceeb tshaj plaws (los yog qhov tseem ceeb) uas tus lej muaj peev xwm tswj tau yog tus cwj mem. Tus thixotropy, uas yog ib qho tseem ceeb ntawm tus cwj pwm ntawm lub cev, ua rau lub cim kua nyeem ntawv los ua kom lub cev ua kua thaum nws ntxhov siab, thiab thaum twg qhov kev tu siab tseg, nws tuaj yeem tiv thaiv hauv ib qho chaw ruaj khov dua. Tus cwj mem yuav tsum tsis ntws los yog kis tom qab dhau qhov kev tshuaj ntsuam. Ntxiv mus, thaum tus number case yog luam tawm ntawm cov ntaub ntawv luam tawm, thaum lub sij hawm ziab (hnyav evaporation), cov dots tswj tau tus qauv zoo li qub, thiab qhov tseem ceeb ntawm tus nqi siab tsis nce, tshwj xeeb tshaj yog nws qhov tsis zoo ntawm qhov tsaus nti ntawm daim duab.
Cov tshuaj muaj zog ntawm cov thixotropic cov neeg ua haujlwm, hauv cov lus yooj yooj yim, yuav txiav cov ntev chains ntawm tus number case, tiv thaiv lawv cov expansion, hos tseem tiv thaiv lub teeb pom kev zoo ntawm cov xim qhuav film. Vim li no, nws yog qhov nyuaj heev uas siv cov phev siv nrog ob qho chaw thixotropic thiab cov paj zoo. Yog li, yog hais tias tus neeg thov kom peb ua glossy plaub-xim tshuaj ntsuam luam ntawv, peb ib txwm siv matte number case thiab ces txheej txheem ntawm cov kua roj vanish. Ntawm chav kawm, peb yuav tsum piav qhia rau cov neeg tuaj yuav tsum tau ua li ntawd. Yog tias koj sau mesh ntawm 75 txoj kab / nti los yog luv dua, qhov no tsis yog qhov nyuaj.
Cov cwj mem tseem muaj lwm cov khoom (los yog lub cev) xws li viscosity, plaub hau xuas (qhov peev xwm ntws los ntawm lub mesh ntawm ib qho nqi), hnyav, dej los yog monomer cov ntsiab lus, khoom tshooj (nutrient) particle size, Hauv (cov dyes), kev sib cais ntawm cov khoom sib txawv xws li cov pigments, khi (cov ntsiab Cheebtsam), cov kuab tshuaj lossis dej, qhov peevxwm ua kom qhuav (qhuav) thiab polymerize (qee cov kaus mom lossis dej-raws hauv qab, siv UV number case).
Thiaj li yuav tau cov qhab nia zoo hauv qhov screen printing, qee tus cwj pwm tsis muaj teeb meem ntawm tus cwj pwm yuav tsum raug tswj. Piv txwv, lub xauv npo ntawm tus cwj pwm yuav tsum raug tswj raws li kev ceev ceev ntawm luam ntawv thiab ziab zom (ntxiv mus, cov tshuab luam ntawv thiab cov khoom siv ziab).
Cov kua roj carbonyl capillary ntawm cov xauv npo ntawm qhov kev tshuaj ntsuam yuav tsum tsis tshua zoo li kom tsis txhob muab tus cwj mem rau qhov screen, txawm tias nws yog qhov chaw.
Cov ntsiab lus ntawm cov hnyav, dej los yog monomer hauv tus cwj mem yuav tsum tswj tau. Yog hais tias tus number case yog tuab heev, nws yuav tsis yooj yim dua los ntawm qhov screen; Yog tias nws yog nyias nyias, nws yog yooj yim ntws, cov duab ntawm daim duab tsis zoo, lub ntsiab txhais tsis zoo, thiab qhov tsaus ntuj nti yog pos huab. Cov ntsiab lus taw tes yuav poob, ua rau muaj kev txo qis tag nrho
Qhov loj me me ntawm cov khoom feem ntau, tshwj xeeb tshaj yog cov xim ntawm cov kev hais plaub, yuav tsum tau tswj tau zoo. Cov zauv ntawm cov toner loj dhau, thiab nws tau ua kom thaiv cov mesh thaum lub mesh qhib, uas hloov xim xim (lightening) ntawm daim duab duab. Hauv UV number case printing, tshwj xeeb tshaj yog tias qhov kev tshuaj ntsuam siv yog ib sab (nyob sab ntawm lub substrate) flattened. Vim tias tus lej yuav nyob hauv lub mesh.
Qhov kev xav ntawm tus cwj mem xaj mus rau dissociate yuav tsum zoo tswj. Nws tseem pauv qhov ntom thiab chromaticity ntawm daim duab thiab ua rau tus number case kom tsis zoo rau lub substrate thaum lub sij hawm luam ntawv.
Lwm yam kev xav uas yuav tsum tswj tau, xws li xim zoo, yuav tsum tau tswj ob txoj hauv kev:
Thawj yog qhov zoo (purity) ntawm cov xim. Cov xim lwm yam xim hauv cov xim tseem ceeb yuav tsum yog me me li sai tau, thiab yuav tsum yog pob tshab kom txo tau qhov teeb meem ntawm "thawj xim".
Qhov thib ob, qhov sib txawv ntawm cov xim yooj yim yog kho raws li cov duab tau theej.
Cov teeb meem no tsis yog tshaj tawm thiab yuav tsum tau kho ntawm 0.95 thiab 1.35 nyob ntawm seb cov duab yuav tsum tau theej (yog luam ntawv qee cov POP / POS lub thawv lub teeb lossis cov chaw nyob ntawm qhov chaw nres tsheb npav, txawm tias ntau dua).
Tswj cov kev hloov no tsis yog ib qhov teeb meem kev teeb meem, nws yog ntau dua ntawm qhov teeb meem kev xav ntawm artistic, thiab nws yog qhov tsis sib xws uas tsis sib xws, vim hais tias qhov kev xaav ntawm daim duab tsis raug sau tseg hauv cov ntsiab lus tshawb fawb.
Tsis tas li ntawd, nco ntsoov tias cov xim muaj ntsis rau qhov khoom koj xav sau. Vim hais tias kev nqus ntawm cov ntaub ntawv luam tawm yuav cuam tshuam cov xim ntawm cov luam tawm thiab cov xim tom qab luam ntawv (cov khoom siv nrog lub zog hygroscopicity xav kom txo tus cwj ntub ntawm tus cwj pwm, tshwj xeeb tshaj yog cov thawj luam tawm xim, uas yog, lub ntsiab xim).
Cov hom ntawv luam feem ntau yog txiav txim siab rau kev ceev ceev (piv txwv li, kev ceev ntawm cov tshuab luam ntawv tawm sai dua qhov ntawm cov tshuab luam ntawv ncaj nraim, thiab lub qhov me me yog me dua), uas kuj muaj qee yam cawv rau ntawm kev hloov ntawm cov chromaticity.
Kev siv cov teeb meem tseem ceeb kuj yog ib qho tseem ceeb uas yuav tsum tswj kev ceev. Nws yog pom tseeb tias qhov ntaus ntawv rov tom qab yuav tsum muaj ntau dua ntawm cov yeeb yam tseem ceeb, thiab tib lub sij hawm, qhov xim yog kho raws li "xim kub" ntawm lub teeb ci. Yog tias muaj cov khoom nruab nrab ntawm cov ntawv luam tawm thiab lub teeb ci (feem ntau diffusing lub teeb), tom qab ntawd ces cov xim ntawm cov khoom thiab cov khoom siv nruab nrab kuj tau luam tawm ntawm kev kub ceev.
Lwm yam teeb meem uas siv rau kev siv luam tawm, xws li kev loj hlob (loj loj), muab lub tswv yim tias qhov chaw nruab nrab ntawm qhov loj tshaj plaws yog qhov chaw nyob ntawm tus thawj me me thawj, yog li ntawd daim duab kawg yuav tsum sib zog. Qhov no txhais tau hais tias nws yog ib qhov tsim nyog yuav tau ua kom qhov kev sib ze ntawm zaj yeeb yaj kiab, tshwj xeeb tshaj yog qhov ceev ntawm cheeb tsam tseem ceeb, thiab hloov qhov ceev ntawm cov ntawv luam tawm.
Cov xim ntawm cov xim yooj yim dua yuav tsum tau tswj kom zoo. Yog cov xim ntawm ib los yog ob peb yam xim tsis txaus, lub tshuab luam ntawv yuav tsum luam tawm xim opaque (los yog opaque number case) ntawm qhov chaw ntawm lub substrate. Tab sis qhov tsis zoo ntawm ua qhov no yog tias nws muaj kev ntxim rau lub ntsiab xim, uas yuav cuam tshuam rau qhov pom kev zoo ntawm daim duab.
Hais txog kev suab nrov, tshwj tsis yog rau daj, tsis muaj xim zoo kiag li yog ntshiab kiag li. Cov xim ntshiab txhua theem yuav tsum muaj peev xwm nqus nws cov xim complementary, thiab thaum tib neeg qhov muag tau txais nws, nws yuav qhia nws cov xim. Hmoov tsis, cyan muaj ib qho me me ntawm daj thiab magenta, thaum magenta muaj ib tug me me ntawm cyan thiab ntau (qee zaum txog li 60%) daj. Nws yog ib qho tseem ceeb rau ntiav ib tug dawb huv magenta, txawm tias nws yog qhov zoo tshaj plaws kev xaiv, nws yuav tsum tau kho nyob rau hauv cov xim sib cais theem.
Lub siab ceev ntawm cov xim (rau ultraviolet tawg nyob rau hauv tshav ntuj) yog lwm qhov sib txawv uas yuav tsum tau tswj. Yog tias luam tawm (xws li kev tawm sab nraud sab nraum zoov sab nraud, lwm yam) kom muaj qhov no, qhov no muaj feem xyuam rau qhov teeb meem ntawm kev xaiv qhov khoom kom yog. Lub teeb pom kev ntawm cov inks feem ntau muab faib ua 1 (tsis pom kev) mus rau 8 (lub teeb pom kev zoo). Yog tias tus number case uas yuav tsum tau mus rau tshav ntuj rau ntau tshaj ob asthiv, tus number case nrog 8 theem ntawm lub teeb ua haujlwm yuav tsum raug xaiv.
Cov duab ntawm cov hnub ci muaj hnub nyoog tsis muaj dab tsi ua rau roj, dej los yog UV number case ntawm tus cwj mem. Nws tsuas yog ntsig txog qhov zoo ntawm tus number case pigment.
Hauv kev sib piv, lub cev (mechanical) thiab tshuaj muaj zog (ziab los yog polymerization) ntawm tus cwj pwm yog kiag li txog nws cov tshuaj muaj pes tsawg leeg. Vim tias cov kabmob UV cov kabmob ntawm UV ua haujlwm tau zoo, cov tshuaj UV ua tau zoo thiab ua haujlwm tsis zoo, thiab tiv taus nag, daus, xuab zeb, hmoov av, kev ua qias tuaj, thiab cov tshuaj siv tshuaj (cov kuab lossis roj). Xaiv UV phev yog txoj kev zoo los tswj qhov kev hloov no.
Kuv yuav siv cov qoob loo kom qhuav qeeb li cas yog tias kuv tsis siv UV number case?
Feem ntau kev siv cov phom sij, thiab qee zaum cov dej hauv qab, yuav tsum kov yeej txoj kev xav ntawm tus cwj pwm kom qhuav ntawm lub vijtsam. Qhov tseem ceeb tshaj ntawm kev tswj yog qhov ua kom ceev lossis dej.
Cov txheej txheem evaporation ntawm diethyl ether tau teem rau qib 1 (evaporation hauv 1 s). Rau feem ntau cov kuab tshuaj, tus neeg ua haujlwm zoo qeeb-ziab yog benzyl cawv (1800 lub sij hawm qeeb qeeb dua ether evaporation).
Rau cov dej ua kua, ntxiv rau 5% ethylene glycol (los yog butyl acetate) ua rau kev sib cais ntawm tus cwj mem thiab qhov screen rau ntawm lub zog ntawm tus kws kho mob.
● Yuav ua li cas tswj txhua tus kab mob sib txawv
Txoj kev tswj cov kev hloov no yog kom luam tawm prints thiab substrates rau ntau hom kev siv siv ib hom ntawv kos duab UV xwb. Rau qee cov ntaub ntawv uas nyuaj rau luam tawm, nws muaj peev xwm ntxiv rau tus cwj mem.
Rau lwm cov ntaub ntawv uas yooj yim luam tawm, xws li iav, txoj kev yog los hloov cov qauv ntawm UV reactor (lub tshuab ziab) kom tus nab npawb tuaj yeem ua tau polymerize saum toj lossis qis dua iav thiab ncav cuag lub cev sib sib zog nqus polymerization, uas yog nquag txuas. Ntawm lub khob.
Dua hauv cov zauv luam tawm tau tam sim no muaj nyob rau hauv kev ua lag luam, qee qhov sib xyaw ntawm UV number case thiab cov xim txhuam hniav, uas muaj qhov zoo ntawm UV number case, xws li tsis ziab ntawm qhov screen.
Tsuas saib xyuas qhov teeb meem ntawm "sib tshooj", uas tej zaum yuav ua rau cov kab nrib pleev ntawm cov ink txheej. Nrog rau UCR / GCR system, number case tshaj hauv qab dub thiab maub kev kho me ntsis yuav raug txwv kom tshem tawm qhov teeb meem no.
● Cov cawv ntawm cov ntaub ntawv luam tawm ntawm cov luam ntawm lub mesh
Tsis hais seb qhov twg lub mesh yog tuab dua los sis thinner, feem ntau, cov khoom ntawm cov ntawv luam tawm kuj yog ib qho loj. Hmoov tsis, peb yuav tsum fim cov kev muaj tiag tias cov ntaub ntawv luam tawm feem ntau yog qhov tseem ceeb tshaj qhov kev tswj ntawm cov neeg ua haujlwm luam ntawv. .
Kev xaiv ntawm substrate feem ntau yog raws li kev siv cov luam thiab cov kev xav tau ntawm tus qhua. Vijtsam tshuab luam ntawv feem ntau tsuas yog xaiv ntawm ib lossis ob. Tsuas yog lub tshuab luam ntawv tuaj yeem piav qhia thiab txiav txim tsim nyog rau txoj kev xaiv, tus neeg tuaj yeem kam txais cov neeg ua haujlwm luam ntawv, piv txwv li, peb lub tuam txhab piav qhia rau cov neeg siv vim li cas peb siv PVC ua npuas ncauj luam tawm nrog ib tus npoo daig, uas yog saum npoo yog du Muaj peev xwm sau meshes zoo.
Txawm li cas los xij, ntxiv rau cov kev xaiv no, muaj ntau yam tsis muaj peev xwm uas muaj feem cuam tshuam rau cov nyhuv luam tawm:
(1) Cov nyom ntawm cov ntaub ntawv luam tawm (thicker or thinner);
(2) cov khoom ntawm cov ntawv thiab cov khoom yas, nrog rau cov ntawv nyeem;
(3) Nws txoj kev los sis tsis yeem txiav txim siab xaiv hom tshuab luam ntawv (platform los yog roller);
(4) me me (loj);
(5) cov khoom siv tshuaj uas txiav txim siab xaiv xaj;
(6) Stability ntawm qhov ntev.
Controllable variables ntawm lub substrate - qhov chaw mob npoo yog qhov tseem ceeb parameter ntsig txog qhov zoo thiab qhov zoo ntawm cov luam cov dots.
Cov ntaub ntawv luam tawm nrog micropores nyob rau saum npoo, xws li daim ntawv coated, kho qhov muag discs, thiab lwm yam., Yuav luam tawm zoo dua cov ntaub ntawv luam tawm ntawm qhov ntxhib qhov. Zoo li cov ntaub ntawv uas tsis muaj ntaub ntawv, cov ntaub ntawv tsis muaj ntaub thiab cov ntawv nthuav dav thiab cov yas, cov ntawv luam tawm thawj tus lej yuav muab "noj" ib co ntawm cov yas txha taub hau thiab qee qhov chaw, kom qhov xim no yuav yog peb li. Said lub ntsiab xim. Hauv lwm lo lus, nws yuav sawv tawm hauv tag nrho cov qauv sau.
Yuav kom tswj tau qhov teeb meem no txhais tau tias kom txo qhov sib txawv ntawm cov xim thawj, lossis qhov xim ntawm cov xim nws tus kheej, los yog ob qho tib si, los kho cov template, ntawm qhov tod tes, rov xaiv cov luam ntawv ntawm cov xim. Thawj cov xim luam tawm raug xaiv raws li nws qhov tseem ceeb hauv daim ntawv luam tawm kawg, piv txwv li, los luam tawm ib lub ntsej muag ntawm ib daim ntawv hygroscopic, zoo dua yog ua ntej magenta lossis liab. Tab sis, yog hais tias nws yog ib qhov scenery ntuj, nws yog qhov zoo dua los luam dub ua ntej.
Nws yuav tsum tau qhia tias qhov kev nyob ruaj ntseg, kev ruaj ntseg thiab thickness ntawm substrate tseem ceeb.
Cov neeg ua haujlwm luam ntawv yuav tsum sawv ntawm tus neeg sab nraud los txiav txim siab seb puas muaj qee cov khoom siv tau los yog tsis thiab qhia tus neeg mob kom ntau li ntau tau.
Lub smoothness ntawm cov khoom thiab lub flatness ntawm qhov saum npoo yog inconsistent. Yuav ua li cas peb yuav xyuas kom meej tias qhov zoo ntawm daim duab ntawm mesh yog ib txwm zoo ib yam?
Hmoov tsis zoo, xws li cov thawv ntawv, cov khoom ua kom sov corrugated, los yog cov ntaub ntawv pov thawj cov yas nrawm feem ntau yog ze rau ± 7 (tshwj xeeb tshaj yog rau cov khoom uas yooj yim rau ncab, qhov tseeb rub ua cov thickness uas tswj tsis tau). Hauv kev sib piv, cov neeg ua haujlwm luam ntawv tsis tuaj yeem tswj cov kev hloov no, uas yog qhov uas yuav luag hloov tsis tau. Txawm li cas los xij, thaum cov neeg muas zaub xav tau plaub lub vijtsam luam tawm ntawm cov khoom siv no, koj yuav tsum tau ua tib zoo saib xyuas kom pom tias qhov tsim nyog yuav tsum tau muab luam tawm rau lwm tog neeg. Qhov no yog qhov tsim nyog tiag.
Qhov teeb meem no tsis yog yooj yim heev, vim hais tias, tshwj xeeb tshaj yog nyob rau hauv mesh luam ntawv, qhov screen thiab template yuav tsum tau yoog rau cov ntaub ntawv luam tawm, uas txhais tau hais tias ntau yam tseem ceeb, xam xws li cov uas siv hauv kev luam ntawv. Cov ntaub ntawv xws li cov ntawv paj rwb, ntau hom tshuaj, cov khoom siv kom muaj zog, thiab textiles.
Yog li ntawd, luam tawm ib qho duab ntawm txhua yam khoom siv coj ncaj ncaj cov ntawv phaj.
Raws li hais dhau los, feem ntau ntawm cov khoom siv lo rau sab nrauv los yog teev los ntawm tus neeg muas zaub, tsis yog luam yeeb tshuaj. Nyob rau hauv cov ntaub ntawv no, tus neeg ua haujlwm luam ntawv tsuas tuaj yeem qhia nws cov tswvyim, cov tswv yim lossis qhia rau cov neeg siv khoom uas muab cov ntaub ntawv tias cov ntaub ntawv tsim kev puas tsuaj rau qhov zoo ntawm lub tshuab luam ntawv.
Cov neeg ua haujlwm luam ntawv yuav tsum piav qhia rau cov neeg siv yog vim li cas cov khoom siv no zoo dua li lwm qhov, yog li peb hais tias xaiv ib qho qis dua rau kev luam ntawv yog qhov kev txiav txim ib nrab ntawm ib nrab.
Feem ntau, uas muaj feem ntau ntawm lub cev thiab tshuaj muaj zog, koj yuav tsum piav qhia rau tus neeg mob kom meej meej, piv txwv li, vim li cas thiaj xaiv cov polystyrene es tsis yog PVC, vim li cas pH daim ntawv pov thawj zoo dua daim ntawv nrog pH ntau, lossis vim li cas ib cov khoom paj rwb zoo dua lwm lub (textile), thiab lwm yam, vim tias nws tuaj yeem xa thiab txhim kho cov ntawv luam kom zoo, yog li ua qhov kawg ntawm cov duab zoo.
Qhov tseeb, qhov chaw ntawm cov khoom ntxhib ntxoo khoom tseem muaj peev xwm tuaj yeem tau txais kev luam zoo, tiam sis lub tshuab luam ntawv yuav tsum kho qhov kev sib tw siv, qhov kev xaiv kev tshuaj ntsuam tshuab, qhov ceev thiab viscosity ntawm tus cwj mem, thiab cov luam tsis muaj, xws li lub scraper. Qhov muaj xws li siab thiab luam ntawv ceev tseem raug kho, uas yog ib txwm muaj feem rau lub zog ntawm lub substrate - nta khoom, nrog rau kev yooj yim lossis rigidity ntawm cov khoom. Piv txwv, xav txog qhov kev xaiv ntawm kev luam ntawv, yog hais tias lub substrate muaj txaus flexibility, nws tuaj yeem luam tawm ntawm lub cylinder xovxwm, uas yog zoo dua rau kev luam ntawv. Lub 0.7 hli tuab khoom tuaj yeem luam tawm rau ntawm cov menyuam yaus thiab cov thickness ntawm 1.5 hli tuaj yeem luam tawm ntawm lub luam yeeb loj loj. Rau cov ntaub ntawv nyuaj, cov ntawv xovxwm yuav tsum raug xaiv.
Hauv ntej, kev siv lub tshuab ua haujlwm tsis zoo ntawm lub tshuab luam ntawv, lub thickness ntawm cov khoom yuav tsum yog tag nrho xam, raws li qhib siab tshaj ntawm daim ntawv cutter. Ua lwm yam lus, qhov xwm txheej ntawm cov nplais ntawm lub substrate tseem raug kho raws li seb lub tshuab luam ntawv lossis lub tshuab luam ntawv kheej siv.
Qhov loj ntawm lub substrate kuj yog ib qhov txawv txav ntawm lub cev uas cuam tshuam rau kev siv xovxwm, qhov screen, phaj ua hom, thiab xaiv ntawm tus number case. Piv txwv, luam tawm ib qho chaw nres tsheb npav nres (120cm × 176cm), lossis daim ntawv qhia loj (120cm × 160cm), kuv siv feem ntau ntawm kev ntsuas ntawm 110 ~ 150 kab / inch (44 ~ 60 kab / cm). Yuav kom tau txais qhov zoo uas cov neeg muas zaub xav tias yuav tau ua.
Qhov no txhais tau tias thaum luam ntawv loj loj, nws yuav tsum tau ua kom tiav li lwm qhov me me.
Qhov tshwj xeeb tshaj yog thaum siv qhov hnyav hauv phom los yog cov dej hauv aqueous, nws yog ib qho tsim nyog yuav tsum yog xaiv lwm yam tseem ceeb uas muaj feem xyuam rau chemistry ntawm cov substrate.
Qhov tseeb yooj yim qhia tau hais tias qee cov khoom siv yas tsis tuaj yeem luam tawm siv dej hauv phooi los yog kuab phom. Ua kom zoo zoo thiab yog xaiv xaiv hom ntawm tus lej, nws yog ib qho tsim nyog yuav tau xaiv cov cwjmem uas muaj kabmob sib kis tau zoo rau lub substrate thaum tib lub sijhawm xav txog kev daws rau lwm yam tsis xws li thixotropic.
Raws li kuv txhawj txog, UV cov phev ntev siv los daws qhov teeb meem no. Kuv tuaj yeem siv tus voj voog UV rau ntau yam ntawv luam tawm. Qhov no txhais tau hais tias cov kev hloov uas yuav tsum tswj tau raug txo kom tsawg.
Kev ruaj ntseg ntawm lub substrate yuav tsum raug kuaj thiab tswj tau zoo. Ntxiv mus, nyob rau hauv plaub-xim tshuaj ntsuam luam ntawv, qhov tseeb yog qhov tseem ceeb tsis hais seb nws yog zoo-tuned los yog tsis.
Yog tias nws muaj peev xwm xaiv tau ntawm ob lub substrates uas zoo sib xws lub cev thiab tshuaj, qhov kev ruaj khov tshaj plaws yuav tsum tau xaiv.
