Flexographic luam ntawv yog dav siv nyob rau hauv ntim printing teb xws li daim ntawv lo, zaj duab xis, ntawv cov khoom, hluav taws xob nplaum vim nws ib puag ncig tiv thaiv, adaptability rau cov ntaub ntawv thiab siab stability. Nyob rau hauv cov txheej txheem ntawm kev kub ceev huab hwm coj ntau lawm, qhov zoo tsis xws luag xws li qhov muag plooj, zuag qhia tag nrho qhov muag plooj thiab ghosting yog feem ntau, uas yuav tsis tsuas yog ua rau cov khoom qis dua thiab cov khoom seem ntawm cov khoom loj, tab sis kuj ua rau cov khoom lag luam qeeb thiab nce nqi ntau lawm. Qhov txhaum tsis yog tshwm sim los ntawm ib qho, tab sis los ntawm kev sib xyaw ua ke ntawm lub siab, tus cwj mem, cov khoom siv phaj, cov khoom siv tsis sib xws, thiab qhov tsis sib xws hauv kev sib koom ua ke ntawm lub tshuab ziab khaub ncaws. Ua ke nrog kev tsim khoom pem hauv ntej, daim ntawv no txheeb xyuas qhov tseem ceeb ntawm kev ua txhaum cai thiab muab cov txheej txheem tswj hwm thiab kev daws teeb meem.
1.Imbalance ntawm kev luam ntawv siab ua rau qhov tsis raug ntawm cov duab thiab cov ntawv.
Kev hloov siab tsis raug yog qhov ua rau cov ntawv tsis meej pem. Flexographic luam ntawv txais lub hauv paus ntsiab lus ntawm mos embossing thiab yog haum rau lub teeb nias hloov luam ntawv. Yog tias kev luam ntawv siab dhau lawm, lub mesh cov menyuam thiab cov menyuam embossing yuav overexpress cov ntawv luam ntawv hloov tau yooj yim, ua rau kev sib kis ntawm dot number case, ua rau luam ntawv phaj ntug adhesion, dot adhesion, cov ntawv tuab thiab lwm yam, uas kuj yog ib qho kev cuam tshuam ntau yam hauv kev lag luam luam ntawv. Hloov pauv, yog tias qhov siab qis dhau lawm, tus cwj mem tsis tuaj yeem hloov pauv mus rau qhov chaw ntawm lub substrate, ua rau cov ntawv ntiav, qhov muag plooj, qhov chaw tsis zoo. Nyob rau tib lub sijhawm, lub siab tsis sib npaug ntawm sab laug thiab sab xis ntawm lub cuab yeej, thiab qhov sib txawv ntawm cov menyuam ncej sib luag, yuav ua rau cov ntawv ntshiab ntawm ib sab thiab cov duab tsis pom ntawm lwm qhov, ua rau cov khoom tsis zoo.
2, Ink kev ua tau zoo tsis yog raws li tus qauv, kev puas tsuaj rau kev luam ntawv molding nyhuv.
Lub viscosity, piv, ziab nrawm ncaj qha txiav txim siab qhov zoo ntawm cov duab thiab cov ntawv sau. Nyob rau hauv txhua hnub ntau lawm, number case dilution yuav ua rau tsis tshua muaj viscosity, fluidity, siab ceev luam ntawv yooj yim rau diffuse, ua rau qhov muag plooj npoo thiab burrs; siab cov viscosity yuav ua rau number case tuab heev, number case hloov tsis zoo, cov ntawv tob yuav tshwm grey thiab fuzzy. Tsis tas li ntawd, kev sib xyaw ntawm tus number case tsis zoo ib yam, cov npuas seem sab hauv, yuav ua rau daim ntawv thov number case tsis sib xws hauv qee qhov chaw, number case ziab ceev thiab tsheb ceev tsis sib xws. Yog tias qhov ziab nrawm nrawm dhau, nws yooj yim ua rau cov duab thiab cov ntawv ziab thiab qhov muag plooj. Yog hais tias nws dries qeeb heev, cov ntaub ntub dej ntub thiab ua rau, ua rau qhov muag plooj thiab ua rau lub ntsej muag, ua rau muaj kev cuam tshuam loj rau qhov pom tseeb ntawm cov ntawv luam tawm.
3. Kev ua haujlwm tsis zoo ntawm cov phaj thiab muab tshuaj txhuam ua rau kev hloov pauv txawv txav.
Flexible resin phaj ntawm kev ntxhib los mos yog mos, daim nplaum zoo ncaj qha txiav txim siab qhov tseeb ntawm kev luam ntawv. Thaum luam ntawv, yog tias cov ntawv luam ntawv nyob rau hauv cov txheej txheem ntawm cov npuas seem, tsis sib npaug, cov npoo curl, tsis sib npaug, thiab lwm yam, yuav tshwm sim hauv zos qhov muag plooj, qhov teeb meem ntawm kev tsis sib haum xeeb hauv kev hloov cov ntawv thiab cov duab. Nyob rau tib lub sijhawm, cov ntawv luam ntawv ntev ntev - siv sijhawm, yuav tshwm sim hnav thiab tsim kua muag, deformation, kev laus, ntawv me me, me me qhov tsis xws luag, thiab lwm yam, tom qab luam ntawv ib txwm ua qhov muag plooj. Qee tus neeg ua haujlwm hauv cov txheej txheem luam ntawv siab - nrawm, yog tias qhov kev xaiv tsis raug ntawm daim kab xev, rub lub phaj, yuav ua rau me ntsis deformation ntawm lub phaj, ua rau cov ntawv sib txawv, dab thiab lwm yam teeb meem tsis tu ncua.
4, Cov khoom siv tsis ruaj khov, tsim kev txav thiab wobble ntxoov ntxoo.
Nyob rau hauv cov xwm txheej ntawm kev kub ceev luam ntawv, kev ruaj ntseg ntawm cov cuab yeej yog lub hauv paus ntawm precision printing. Nyob rau hauv cov txheej txheem ntawm kev nthuav dav thiab kev tsim kho tshiab, qhov kev hloov pauv ntau dhau ntawm qhov nro yuav ua rau cov yeeb yaj kiab thiab ntawv substrate xws li nro, kev co thiab kev txav chaw. Txhua qhov sib txawv me ntsis hauv txoj hauj lwm imprint tuaj yeem ua rau ghosting thiab tsis meej pem ntawm cov duab thiab cov ntawv. Tsis tas li ntawd, kev taw qhia yob, embossing rau cov menyuam nto ntog qias neeg, nplua, hnav, deformation, thiab ntau yam xim ntawm lub sijhawm ua haujlwm asynchronous, yuav cuam tshuam rau kev ruaj ntseg ntawm cov khoom noj. Cov khoom siv tsis yog calibrated concentricity rau lub sij hawm ntev, qhov kis tau tus mob clearance loj heev, lub vibration yog loj thaum khiav ntawm kev kub ceev, kuj yog ib qho tseem ceeb vim li cas uas ua rau cov duab thiab cov ntawv mus plooj.
5, dryness thiab ib puag ncig tsis sib xws, exacerbating defects.
Lub tshuab ziab khaub ncaws yog cov kauj ruam tseem ceeb los xyuas kom meej cov duab thiab cov ntawv nyeem. Tsis tshua muaj kev ziab khaub ncaws, cua kub tsis txaus, huab cua ducts blockage, thiab lwm yam, yuav ua rau tus number case tsis tuaj yeem qhuav sai, ua rau ink diffusion, cov duab thiab cov ntawv nyeem vim yog cov khoom siv tom ntej stacking thiab kev sib txhuam thiab qhov muag plooj. Nyob rau tib lub sijhawm, kev ua haujlwm kub thiab av noo yuav cuam tshuam rau cov duab ntawm cov substrate thiab number case kev ua haujlwm. Yog tias cov av noo siab dhau lawm, cov khoom yuav raug ncab vim cov av noo, tus number case yuav maj mam qhuav. Yog tias cov av noo tsawg dhau lawm, cov khoom siv yuav tsim hluav taws xob zoo li qub, tus number case evaporation sai heev, cov no yuav ua rau cov duab tsis zoo thiab cov ntawv sau ua kom zoo, qhov muag plooj.
6, Cov Txheej Txheem Kev Tiv Thaiv thiab Rectification Control Plan
Raws li cov laj thawj saum toj no, lub rooj cob qhia yuav tsum tsim kom muaj cov txheej txheem kev hloov kho tshuab thiab cov txheej txheem tswj kom zoo. Hauv kev debugging, ua raws li lub hauv paus ntsiab lus ntawm lub teeb siab luam ntawv, kom raug calibrate lub parallelism thiab luam ntawv siab ntawm cov menyuam ncej los tiv thaiv kev kub siab paste thiab tsis tshua muaj siab tsis muaj luam ntawv; Standardize number case blending qauv, tsis tu ncua kuaj tus number case viscosity kom paub meej tias tus number case ruaj khov. Ntxuav lub phaj cov menyuam thiab phaj ua ntej muab tshuaj txhuam kom du thiab npuas -dawb nto. Tsis tu ncua hloov cov laus thiab hnav steel daim hlau. Ua ntej-kev tsim khoom Calibrate cov cuab yeej nro thiab kho qhov system kom tshem tawm cov menyuam nto impurities, xyuas kom zoo noj. Thaum kawg, phim qhov ceev thiab ziab tsis, ntxuav lub tshuab ziab khaub ncaws, ua kom ruaj khov ntawm qhov chaw tsim khoom ntawm lub rooj cob qhia, tshem tawm qhov tsis pom kev ntawm cov ntawv los ntawm qhov chaw, thiab txhim kho cov luam tawm tawm los thiab kev ruaj khov.
