Raws li cov khoom tseem ceeb hauv kev luam ntawv kev lag luam, flexographic tshuab luam ntawv tau siv dav hauv kev ntim khoom, sau npe, tshaj tawm thiab lwm thaj teb. Txawm li cas los xij, thaum siv, flexographic luam ntawv nias feem ntau ntsib kev ua tsis tiav, thiab lwm yam Cov teeb meem no tsuas yog cuam tshuam rau cov teeb meem luam tawm zoo, tab sis kuj yuav ua rau muaj kev txo qis hauv kev ua tau zoo nyob rau hauv ntau dua nyob rau hauv ntau dua hauv kev ua tau zoo nyob rau hauv ntau lawm hauv kev ua tau zoo nyob rau hauv ntau lawm hauv kev ua haujlwm. Yog li ntawd, daws cov no prints ua tsis tiav yog qhov tseem ceeb los txhim kho luam ntawv zoo thiab ua tau zoo.
Dab tsi yog cov hom ntawm cov luam ntawv swb ntawm flexographic luam ntawv presses?
Ink tsub zuj zuj ntawm: Thaum number cask accumulates ntawm cov khoom lossis luam tawm cov khoom lag luam, cov pa tsis sib xws yuav ua rau ntawm cov khoom luam tawm, cuam tshuam nws cov tsos.
- Luam Ntawv Fuzziness: Vim yog cov chaw tsis raug ntawm cov phaj, anilox cov menyuam lossis luam ntawv siab, cov ntawv luam tawm duab thiab npoo tshwm rau tawg plooj.
- Kev sib txawv xim: cov xim ntawm cov khoom luam tawm yog tsis sib xws nrog cov kev cia siab, uas tej zaum yuav tshwm sim los ntawm cov number cascurate sib xyaw ntawm cov number case lossis paug ntawm cov kua mem.
- Kev luam tawm Wedefering hais txog cov duab rov ua dua lossis cov ntawv sau uas tshwm sim los ntawm cov luam ntawv tsis sib xws ntawm cov ntawv luam tawm thiab anilox cov menyuam lossis cov ntaub ntawv nrawm nrawm nrawm.
- Vim tias siv sijhawm ntev, cov npoo av maj mam hnav ris tsho, uas ua rau txo qis zoo thiab cov npoo plooj ntawm cov duab luam tawm.
Yuav kuaj li cas cov khoom ua tiav hauv Flexographic Printing Presses?
Kuaj cov tshuab luam ntawv swb hauv cov ntawv luam ntawv flexographic xav tau kev txiav txim siab ntau yam ntawm ntau qhov:
- Thaum kuaj cov teeb meem luam tawm hauv Flexographic Printing Presses, cov kev txiav txim siab tshaj plaws yuav tsum tau ua los ntawm ntau qhov ntev:
- Thaum saib cov ntawv luam tawm, cov luam tawm yuav tsum tau tshuaj xyuas kom tsis xws luag xws li kev txiav txim siab ua ntej thiaj li ua tau ntawm qhov tsis muaj peev xwm ua tau.
- Ua kev soj ntsuam ntau tshaj plaws ntawm txhua qhov tseem ceeb ntawm cov tshuab luam ntawv, xws li lub tshuab luam ntawv, los txiav txim siab seb puas muaj teeb meem xws li hnav, txhaws lossis paug.
- Thaum siv cov cuab yeej siv tau xws li cov cuab yeej tshaj lij xws li cov kev tuaj saib hauv Ink thiab cov kev ntsuas siab tuaj yeem siv rau kev ntsuas cov luam tawm yog qhov tsim nyog.
- Thaum kev tshawb nrhiav cov luam tawm, peb tau saib cov chaw ntawm cov tseem ceeb xws li kev luam ntawv ceev, thiab ua kom haum raws li qhov xav tau tiag tiag ntawm kev luam ntawv.
Yuav ua li cas daws cov khoom lag luam tsis ua rau los ntawm cov teeb meem tsis zoo?
Txog kev luam ntawv tsis tshwm sim los ntawm cov teeb meem tsis muaj ntxhiab, ntsuas hauv qab no tuaj yeem coj:
- Kho cov viscosity ntawm ak ink: kho cov kab viscosity ntawm tus num viscosity raws li cov kev xav tau tshwj xeeb los tiv thaiv nws cov kev tsub zuj zuj lossis tsis zoo kom qhuav cov nyhuv. Ntxiv cov dispersants rau cov number cas tuaj yeem txo cov agglomeration thiab dispersion ntawm cov kua mem kua, kom cov number case tswj viscosity tsawg. Cov viscosity siab dhau yuav ua rau cov kua txob qis dua, thaum tsis muaj viscosity tsawg dhau yuav ua rau tsis zoo ziab cov nyhuv ntawm cov number case.
- Txhim kho cov kua mem tov sib xyaw: xyuas kom meej tias cov xim ntawm tus cwj mem yog qhov tseeb thiab tiv thaiv kev sib txawv xim. Cov xim ntawm tus kua mis tsuas yog nyob ntawm qhov xwm txheej xws li kev sib cuam tshuam ntawm cov xim pegment thiab adsorption lub zog ntawm cov kuab tshuaj molecules ntawm cov particle. Nyob rau hauv cov txheej txheem ntawm tov inks, nws yog ib qho yuav tsum tau zoo sib xyaw raws li ib qho kev piv txwv thiab ib txwm sim cov xim ntawm tus ees kom ntseeg tau qhov tseeb ntawm kev sib xyaw.
- Ntxuav tus cwj mem kua mem pa tsis tu ncua kom tsis txhob muaj ntxhiab tsw thiab thaiv. Kev tu tsis tu ncua ntawm Ink system pab kom tshem tawm cov mem kua mem thiab lwm yam impurities, kom tag nrho cov mem dej mem dej khiav zoo.
Dab tsi yog kev tawm tsam rau kev luam ntawv tsis ua rau los ntawm phaj thiab anilox cov menyuam teeb meem?
Cov kev ntsuas hauv qab no tuaj yeem coj mus luam ntawv tsis ua rau los ntawm phaj thiab anilox cov menyuam cov teeb meem:
- Nquag hloov cov paib uas zoo hnav kom ua kom paub meej ntawm kev luam ntawv. Thaum siv daim hlau tshiab, ua tib zoo saib xyuas cov inks uas tsim nyog thiab cov ntaub ntawv ntub dej kom tsis txhob hnav los yog de-phaj. Txij li thaum lub phaj hnav yuav txo tau qhov zoo ntawm cov duab luam tawm, nws yog qhov tsim nyog los hloov nws tsis tu ncua kom ntseeg tau zoo luam ntawv.
- Nquag ntxuav thiab tswj cov menyuam anilox: Xyuas kom meej tias qhov chaw ntawm Anilox cov menyuam tau ceev kom huv thiab cov ntxaij huv. Hu rau ntu ntawm anilox cov menyuam thiab cov ntawv yuav tsum tau ceev kom huv kom tsis txhob muaj fiber tawg vim hnav. Kev nyiam huv ntawm anilox cov menyuam tau txiav txim siab ua haujlwm ntawm kev ua tau zoo thiab kev pom tseeb ntawm cov khoom luam tawm.
- Kho lub siab tiv thaiv ntawm Anilox cov menyuam thiab lub tshuab luam ntawv: kho lub siab tiv thaiv raws li cov kev xav tau tshwj xeeb los ntawm kev sib tsoo lossis dab thaum lub sijhawm luam ntawv. Siab dhau los yog tsawg dhau kev sib cuag siab yuav muaj qhov tsis zoo rau qhov zoo ntawm kev luam tawm.
Yuav ua li cas kho cov chaw ntawm flexographic luam ntawv xovxwm kom tiv thaiv cov luam ntawv tsis ua?
Txhawm rau tiv thaiv cov luam ntawv swb, cov chaw ntawm cov ntawv luam ntawv flexographic tau tuaj yeem hloov kho:
- Txhawm rau kom ua kom zoo dua lub tshuab luam ntawv ceev, peb hloov kho lub tshuab luam ntawv raws li lub sijhawm qhuav ntawm cov number case ntawm tus cwj mem thiab cov yam ntxwv ntawm lub phaj. Feem ntau, thaum cov xim sib txawv lossis ntau qhov sib txawv ntawm cov khoom lag luam tau tsim tawm hauv tib xovxwm luam ntawv yuav tsum tau xaiv kom tau raws li cov neeg siv khoom kom ua tau zoo thiab ua tau zoo. Kev luam ntawv ceev dhau yuav ua rau tsis zoo ziab ntawm tus cwj mem, thaum qeeb dhau luam ntawv ceev yuav txo qis kev ua tau zoo.
- Kho lub tshuab luam ntawv siab: ua kom lub siab yog nyob rau hauv cov phaj tsim nyog kom txo cov phaj hnav thiab zam kom tsis txhob blrurring thaum lub tshuab luam ntawv. Thaum ua kom zoo dua ntawm tus number case, txo qhov ua haujlwm nrawm ntawm cov tshuab luam ntawv kom ntau li ntau tau los txo cov teeb meem xws li cov cim thiab npuas nyob rau saum npoo ntawm cov khoom luam tawm. Lub tshuab luam ntawv siab yuav tsum tau hloov kho kom zoo raws li cov luam ntawv siv thiab cov kev xav tau tshwj xeeb luam ntawv.
- Kev ntsuas kev ntsuas tsis tu ncua ntawm cov ntawv luam ntawv: Txhua qhov tsis yog cov xovxwm luam ntawv yog ib nrab hloov kho kom ntseeg tau tias nws cov luam ntawv raug. Kev ntsuas tsis tu ncua yog qhov tseem ceeb heev thiab txoj haujlwm nyuaj. Los ntawm kev ntsuas hluav taws xob, peb tuaj yeem ua kom muaj kev ruaj ntseg thiab qhov raug ntawm cov tub rog ua haujlwm, yog li ua kom zoo tshaj plaws ntawm kev luam ntawv.
- Xaiv cov inks zoo thiab cov khoom luam tawm: xaiv cov inks thiab cov ntaub ntawv luam tawm uas phim cov haujlwm luam ntawv los txhim kho txhua yam zoo ntawm kev luam ntawv. Thaum tsim cov ntawv luam ntawv, nws yog ib qho tsim nyog los xav txog qhov kev xav tau ntawm kev ua tau zoo ntawm cov ntaub ntawv xws li ntawv thiab number case. Siv cov inks zoo thiab cov khoom luam tawm tuaj yeem nqa cov txiaj ntsig kev luam ntawv tau ntev dua qub.
