Nyob rau hauv qhov tseeb ntau lawm ntawmCI (Central Impression) flexographic tshuab luam ntawv, xim inconsistency yog ib qho teeb meem tseem ceeb heev. Nws tshwm sim ntau dua nyob rau hauv siab - ceev nruam luam ntawv rau ntim zaub mov, ntim tshuaj txhua hnub, thiab daim ntawv thov zaj duab xis yas. Cov xim tsis ruaj khov tsis yog tsuas yog ua rau lub ntsej muag zoo ib yam ntawm cov khoom luam tawm tab sis kuj ua rau cov xim sib txawv ntawm cov khoom sib txawv thaum lub sij hawm tas li. Qhov no ua rau cov khoom pov tseg, ua rau muaj kev tswj xyuas kom zoo, thiab cuam tshuam qhov khoom xa tuaj zaum kawg. Yog li ntawd, kev txheeb xyuas cov hauv paus hauv paus thiab kev npaj cov kev daws teeb meem yog qhov tseem ceeb rau kev txhawb nqa ntau lawm ruaj khov thiab luam ntawv zoo.
I. Lub ntsiab ua rau xim tsis sib xws hauv CI Flexographic Printing Machine
1.Ink Viscosity Fluctuation: Thaum khiav ntawm kev ua haujlwm siab, hnyav hauv tus number case evaporates sai. Qhov no ncaj qha hloov tus lej viscosity, hloov pauv tus lej hloov pauv tus lej, thiab ua rau pom tseeb xim txawv txawm tias tsis hloov pauv qhov ntsuas.
2.Unmatched Printing Pressure thiab Roller Aging: Kev ntsuas siab tsis raug lossis ntev - lub sij hawm hnav ntawm cov tshuab luam ntawv yuav ua rau cov xim tsis sib xws ntawm cov substrates. Qhov no ua rau cov ntawv luam tawm tsis ruaj khov thoob plaws hauv kev tsim khoom thiab ua rau cov xim tsis sib xws.
3.Substrate Tension Unsteadiness: Cov khoom siv tau yooj yim xws li PE, BOPP thiab CPP yog rhiab heev rau kev hloov nro. Tsis ruaj khov nro yooj yim ua rau substrate stretching thiab deformation, puas dot reproduction raug, thiab nws thiaj li ua rau xim hloov.
4.Anilox Cov Menyuam Tsis Ua Haujlwm: Thaiv lossis abraded anilox hlwb tsis tuaj yeem xa tus lej sib npaug thiab ruaj khov. Feem ntau cov tsis xws luag muaj xws li faded printing tones thiab tsis tu ncua stripe marks ntawm tiav prints.
5.Machine Speed Variation: nquag pib- nres kev khiav hauj lwm thiab kev hloov ceev ceev ua rau qhov ruaj khov ntawm kev hloov tus cwj mem. Kev tuav lub nrawm nrawm yog qhov tseem ceeb kom ua kom cov xim tso zis tsis sib xws txhua lub sijhawm.
6.Ambient Temperature and Humidity: Rhiav kub thiab av noo variations cuam tshuam tus number case ziab ceev thiab substrate lub cev muaj zog. Ntev- lub sijhawm ua haujlwm nyob rau hauv qhov chaw tsis ruaj khov yuav ua rau qeeb, maj mam xim xim hauv cov khoom luam tawm.

Txhawm rau ua kom pom qhov zoo ntawm kev ua haujlwm ruaj khov ntawm CI flexographic tshuab luam ntawv hauv kev ua haujlwm tiag, koj tuaj yeem saib cov yeeb yaj kiab hauv qab no:
II. Kev daws rau xim tsis sib xws hauvCI Flexographic Printing Tshuab
1.Tau txais kev txhim khu kev qha tsis siv neeg viscosity maub los. Kev hloov ntawm phau ntawv yuav zoo li drift, yog li cia cov cuab yeej tuav tus cwj mem nyob ruaj khov. Hauv kev khiav ntev, nws them rau qhov pom - kuaj xyuas thiab nplua- kho tus cwj mem tam sim no thiab tom qab ntawd - xim nyob ntawm lub hom phiaj ntawd hauvflexo luam ntawv xovxwm.
2.Txoj kev xav, roj hmab, thiab phaj yob ua rau lub siab tsis sib xws thiab xim hloov. Tshawb xyuas lawv tsis tu ncua thiab ua raws li tus qauv calibration ib kauj ruam. Qhov ntawd ib leeg kho ntau lub siab- cuam tshuam txog kev hloov pauv thiab ua rau kev luam ntawv ruaj khov dua tuaj yeem kwv yees tau.
3.A siab -precision tag nrho servo nro system ua rau muaj qhov sib txawv. Teem cov tsis muaj kev ywj pheej rau txhua yam khoom yog li substrate deformation tsis cuam tshuam xim. Calibrate lub kaw lus ua ntej koj pib txoj haujlwm, thiab koj tau teem caij rau kev khiav haujlwm ruaj khov txhua hnub.
4.Anilox rollers xav tau kev saib xyuas zoo ib yam. Kom lawv ua haujlwm huv ntawm lub sijhawm teem tseg kom tsis txhob muaj cov cell los ntawm clogging. Kuaj kev hloov pauv kev ua haujlwm ib ntus thiab hloov cov yob thaum lawv tsoo lawv cov kev pabcuam txwv. Txawm hloov txhais tau tias txawm xim nyob rau hauvsaj zawg zog ntim printing.
5. Zam tsis tas pib thiab nres. Khiav cov xovxwm ntawm qhov ceev tsis tu ncua ua kom tus number case hloov mus du, uas txo qis cov xim sib txawv uas qhia tau tias tsis ruaj khov. Cia li cia lub tshuab ua kom nws nrawm.
6.Ua kom koj lub khw ib puag ncig tswj. Swings nyob rau hauv qhov kub thiab av noo mess nrog number case kom qhuav thiab cov khoom coj cwj pwm. Tuav cov no kom ruaj khov, thiab koj yuav pom cov teeb meem xim tsawg dua los ntawm evaporation lossis substrate hloov.
