Tus pib cov lus qhia mus tshuaj ntsuam luam ntawv nrog UV number cask

UV npo luam ntawv cuam tshuam nrog peb theem tseem ceeb: tshuaj ntsuam, ncab, kev siv tshuaj txhuam, kom muaj kev cia kom paub tseeb; Kev Lag Luam Kev Lag Luam, tsom mus rau ink viscosity kev hloov kho, ntsuas chaw (ntsuas hluav taws xob siab, nrawm) thiab UV teeb lub zog tswj thiab xim; Post - Ua, suav nrog kev kuaj xyuas zoo (cov khoom siv tshuaj nplaum, tshuaj ntxuav tes, UV teeb tsis zoo, ua kom muaj kev ntsuas hluav taws xob).

UV npo luam ntawv yog lub tswv yim tshiab txheej txheem uas ua ke ultraviolet kho tshuab nrog cov tshuaj ntsuam cov luam ntawv. Nws cov tub ntxhais nyob hauv qhov kev kho mob sai li ntawm cov kua dej uas tsis zoo los ntawm kev siv lub sijhawm ntev thiab cov khoom siv tsis tau ntawm cov number cask. Tsis zoo li cov kuab ncu - Cov inks, nws yog iM95nm lossis 395nm lossis 395nm lossis 395nm lossis 395nm lossis 395nm lossis 395nm lossis 395nm lossis 395nm lossis 395nd Hla - kev txuas polymerization ntawm resin thiab monomer los ua ib qho khoom siv peb {}} dimensional network txheej duab zaj duab xis txheej. Qhov kev txhaj tshuaj sai no tsis tsuas yog tshem tawm cov tshuab ziab khaub ncaws ua kom qhuav, muaj cov tshuaj ntsuab}} - kev siv daim ntawv thov.

Rau cov pib tshiab, qhov zoo ntawm UV vijtsam luam ntawv yog xav txog hauv nws cov khoom siv dav dav. Txawm hais tias nws tsis yog -}} Cov ntaub qhwv, iav, lossis cov ntaub qhwv ntsej muag yas xws li cov ntaub ntawv yas ua kom ncaj qha yam tsis muaj kev tshaj tawm ncaj qha. Piv txwv li, tsis siv neeg tsis siv neeg yob - {kua nplaum}}} ke {{{{{{{{{{6 {} {} {} {{6 {6 { Txawm tias cov substrates zoo li cua sov {{8}, polypropylene (piv txwv li UV kho cov txheej txheem ua kom cua sov tsawg, tiv thaiv kev ntaus rog lossis kev puas tsuaj. Cov versatility tshem tawm cov kev xav tau them tus nqi ua ntej ua ntej- txheej txheej qib rau me me rau ntau ntau lawm cov khoom loj.

1. Cov khoom siv tseem ceeb
Lub vijtsam luam ntawv: phau ntawv lossis cov qauv tsis siv neeg muaj cov khoom siv tsis zoo, muaj cov khoom siv tsis zoo no yog tsim nyog rau cov khoom siv tsis zoo no xws li cov khoom siv hluav taws xob tsis zoo no thiab kev txhawb nqa Dov - rau-yob tas mus li luam ntawv.
UV Kho cov txheej txheem: Tus Ink Kho Zog Zog (ntau dua lossis sib npaug ntawm 120MJ / cms}} {} {{1} {{1} {{1} {{1} {{1} -
Vijtsam: Polyester lossis nylon npo (240-300 mesh, 6-10 hli thickness) yog siv nrog txhuas lub thav duab. Lub nro ntawm lub vijtsam yuav tsum tau ib yam kom tsis txhob muaj kev cuam tshuam ntawm tus qauv thaum lub sijhawm luam ntawv.

2. Cov ntaub ntawv tseem ceeb
UV Ink: Xaiv Ink muaj siab - qhov loj me} qhov me me <1μm) kom ntseeg tau 7 {} 8 lub teeb tiv taus. Piv txwv li, Marabu Uv - hv series number case yuav txhim kho cov ntawv luam tawm rau cov khoom luam tawm xws li iav thiab hlau los ntawm kev ntxiv adhesion shipper.
Scraper thiab Ink Rov qab riam: Polyurethane scraper nrog hardness ntawm hardness ntawm phaj nplaum, thiab cov hniav yuav tsum tau khaws cia ntse kom ntseeg tau tias cov hloov pauv ntawm number case.
Cov cuab yeej siv: Photosensitive kua nplaum (tov nrog dichromate thiab gelatin), tus tsim tawm (20-25% sodium hydrium hydrocide tov), thiab lwm yam.

Degreasing nrog sodium hydroxide tov (feem ntau 20 {{}}}}}}}}}}}}}} Tom qab degreasing, lub vijtsam (polyester lossis nylon, 240 {}} Khev muaj ncab tshuab, tom qab ntawd ruaj ntseg rau cov ncej txhuas nrog kev lag luam aluminium nrog kev lag luam-qib nplaum. Ntug pov tseg nrog cov kab xev ib sab xwb tsuas yog txwv tsis pub txwv tsis pub siv tshuaj tsis pub dhau tab sis kuj tiv thaiv cov kab mob ntawm cov tshuaj corrosion thaum lub sijhawm tu.

Txheej thiab kis

Cov duab thaij emulsion - Feem ntau ib qho dual-}}}} ib puag ncig kom tsis txhob pinholes. Ib txheej sib zog nrog lub ntse ntse sawv daws tau faib; Ob lub tsho tiv no rau txhua sab (qhuav ntawm 35- 40℃ntawm lub tsho ntev) ua tiav cov tuab tagnrho ua tiav thiab daws teeb meem. Thaum lub sij hawm kis tau, UV lub teeb (365nm wavelength) tawv tawv lub emulsion tshwj tsis yog hauv thaj chaw npog los ntawm cov yeeb yaj kiab. Lub sijhawm raug sib txawv los ntawm hom emulsion: 18 {}} Post-raug, tsim nyob rau hauv 30-40℃tsim tawm (ib qho kev ua tau zoo me ntsis) yuav tsum tau maj mam muab cov ntsiab lus maj mam kom tsis txhob muaj kev tshem tawm kom tsis txhob mob plab.

Kev ntxuav thiab chaw cia khoom

Post -}}}}}}}}}} Cov ncauj lus tsis pub dhau 30 feeb tsis pub dhau 30 feeb los tiv thaiv ncej tsis muaj zog. Kom qhuav ntawm 40 {- 50℃hauv ib qho zoo {}} pa av tsis muaj dej hiav txwv tsis muaj dab tsi uas ua rau cov khoom pov tseg emulsion thaum lub sijhawm cia. Khaws cov ntxaij vab tshaus hauv opaque, noo-pov thawj khoom (txheeb ze cov av noo<60%) preserves emulsion integrity, extending their lifespan to 500+ prints with proper care.

2. Luam Ntawv Ua Haujlwm
Ink Npaj: Kho lub viscosity (20-50Mpa · s) raws li cov yam ntxwv ntawm substrate, ntxiv tsawg dua 10% ntawm diluent (thiab do zoo kom tsis txhob stratification.
Parameter Teem: Kev ntsuam xyuas qhov sib nrug 1-5mm, cov ntawv sib txuas nrog cov khoom siv ceev dua raws li tus mem kua dog ceev (xws li cov tshuaj kho tau zoo tuaj yeem siv nrawm dua).
Kho tswj hwm: UV teeb lub zog yuav tsum tau npog tag nrho cov chaw luam ntawv, thiab tus conveyor siv ceev ceev yuav tsum phim cov txheej hauv plab tuab. Piv txwv li, dub mem kua num yuav tsum tau txo kom nrawm rau nce lub sijhawm.

3. Post -} ua
Kev Soj Ntsuam Zoo: Tshuaj nplaum los ntawm ntau txoj kev sib tw xeem, thiab ntsuas cov zaj duab xis hardness nrog lub hardness cwj mem (yuav tsum tau mus txog 3h lossis ntau dua).
Cov Khoom Siv Kho Khoom Siv: ntxuav lub nozzle thiab lub teeb ci tsis tu ncua kom tsis txhob kho tsis txaus vim UV Zog Attenuation.

1. Ink Kev Ua Haujlwm Zoo Tshaj Plaws
Viscosity tswj: nyob rau hauv tsawg ib puag ncig ib puag ncig, viscosity ntawm tus kua txob nce ntxiv, thiab cov flucing agoning tus neeg sawv cev (xws li UVVM) lossis cua sov tus cwj mem rau 22-25 degree.
Kev kho cov khoom sib piv: Xaiv lub teeb lub teeb ci raws li cov yam ntxwv ntawm tus cwj mem. Piv txwv li, Elastic Ink yuav tsum tau qis {{1} Zog} Lub zog}}}}}}}} mercury teeb rau kev nkag mus.

2. Substrate pretricement
Cov ntaub ntawv saum npoo: Cov ntaub ntawv ntom xws li hlau thiab iav yuav tsum tau kho nrog corona lossis tshuaj tsuag nrog cov tshuaj tiv thaiv corona (xws li Plr cov tshuaj ntxuav kom ntau tshaj 50mn / m.
Kev tswj kom kub: preheat lub substrate mus rau 30-40℃ua ntej luam tawm kom txhim kho lub zog ntawm tus number case ntawm tus cwjpwm thiab txo ntau tiam ntawm npuas.

3. Kev tswj cov ntsiab lus
Scraper lub kaum sab xis: 45-75℃kaum ntse ntse tuaj yeem sib piv tus nqi ntawm number case thiab qauv meej. Txog kev luam ntawv zoo, nws pom zoo kom siv cov scraper nrog kev tawv ntawm 80 thiab txo lub kaum sab xis.
Kev Ntsuam Xyuas Cov nrees: tsis muaj txiaj ntsig tau yooj yim tuaj yeem ua tau yooj yim ua rau smearing. Nws raug nquahu kom siv lub nro ntsuas kom ntseeg tau tias qhov nro muaj txiaj ntsig ib square centimeter yog nyob hauv thaj tsam ntawm 20-25n.

1. Cov adhodion txaus
Vim li cas: roj nyob rau saum npoo ntawm substrate, kho lub zog tsis txaus, thiab mismatch ntawm number case thiab lub qab hau.
Countermeasures: So lub zog nrog dej cawv, thiab xaiv Ink muaj adveyor kev txhawb nqa (xws li Marabu U6 {0} hv 4).

2. Phaj Muab tshuaj txhuam thiab kua mem kua to
Vim li cas: lub vijtsam tshuaj ntsuam yog qhov tsawg heev, daim scraper siab yog ntau dhau, thiab Ink viscosity yog ntau dhau.
Kev suav daws: Hloov lub vijtsam nrog cov mesh loj ntawm 300 lossis ntau dua, txo cov scraper kom siab, thiab ntxiv 5% rau kev kho cov viscosity.

3. Ink Txheej npuas
Vim li cas: tsis txaus nyob rau hauvk nplawm, siab ambient vaum, thiab muaj zog substrate haum.
Kev Countermeasure: cia tus number case sawv ntsug rau 30 feeb ua ntej kev luam ntawv, tswj cov av noo ntawm 60%}} 60 2}, thiab xaiv cov number case nrog cov roj qis lossis ua ntej coated teeb txheej.

4. Kev sib txawv
Vim li cas: Tus number case tsis tau sib xyaw tag nrho, qhov screen tau thaiv, thiab lub sijhawm kho tau hloov pauv.
Kev CounterMeas: Siv cov nplai hluav taws xob kom ntsuas tau cov tshuaj ntxiv, tsis tu ncua ntxuav lub vijtsam nrog ultrasonic kev kho cov ntaub ntawv parameter.
