Thaum lub sijhawm ua haujlwm siab ceev ntawm qhov kev xav hauv nruab nrab ntawm Flexo xovxwm, hluav taws xob zoo li qub feem ntau dhau los ua qhov teeb meem zais tab sis ua rau muaj kev puas tsuaj loj heev. Nws accumulates ntsiag to thiab tuaj yeem ua rau ntau yam tsis xws luag, xws li kev nyiam ntawm cov plua plav lossis cov plaub hau rau hauv cov substrate, uas ua rau qias neeg prints. Nws kuj tseem tuaj yeem ua rau tus cwj mem splattering, hloov pauv tsis sib xws, tsis muaj cov dots, lossis cov kab hauv qab (feem ntau hu ua "whiskering"). Tsis tas li ntawd, nws tuaj yeem ua rau muaj teeb meem xws li misaligned winding thiab zaj duab xis thaiv, cuam tshuam loj heev rau kev tsim khoom thiab cov khoom zoo. Yog li ntawd, kev tswj xyuas hluav taws xob zoo li qub tau dhau los ua qhov tseem ceeb rau kev ua kom muaj kev luam ntawv zoo.
Qhov hluav taws xob zoo li qub tuaj ntawm qhov twg?
Hauv flexographic luam ntawv, hluav taws xob zoo li qub feem ntau tshwm sim los ntawm ntau theem: piv txwv li, cov yeeb yaj kiab polymer (xws li BOPP thiab PE) los yog ntawv feem ntau frictionally sib cuag thiab cais tawm ntawm cov menyuam qhov chaw thaum lub sij hawm unwinding, ntau impressions, thiab winding. Kev tswj tsis raug ntawm ambient kub thiab av noo, tshwj xeeb tshaj yog nyob rau hauv qis-kub thiab qhuav tej yam kev mob, ntxiv txhawb cov tsub zuj zuj ntawm static hluav taws xob. Ua ke nrog kev ua haujlwm siab nrawm nrawm ntawm cov cuab yeej, tiam thiab kev sib sau ua ke ntawm cov nqi yog exacerbated.

Systematic Electrostatic Control Solutions
1.Precise Environmental Control: Ua kom ruaj khov thiab tsim nyog rhiav ib puag ncig yog lub hauv paus rau kev ua haujlwm zoo ntawm ci Flexo xovxwm. Khaws cov av noo nyob rau thaj tsam ntawm 55% -65% RH. Tsim nyog cov av noo txhim khu huab cua conductivity, accelerating lub ntuj dissipation ntawm hluav taws xob zoo li qub. Advanced industrial humidification / dehumidification systems yuav tsum tau ntsia kom ua tiav qhov kub thiab av noo.
Humidity Control
Static Eliminator
2.Active Static Elimination: Nruab Static Eliminators
Qhov no yog qhov ncaj qha thiab cov ntsiab lus tseem ceeb tshaj plaws. Precisely nruab static eliminators ntawm cov haujlwm tseem ceeb:
●Unwinding Unit: Neutralize lub substrate ua ntej nws nkag mus rau hauv lub tshuab luam ntawv seem los tiv thaiv cov nqi zoo li qub los ntawm kev nqa mus tom ntej.
●Nruab nrab ntawm Txhua Lub Chaw Luam Ntawv: Tshem tawm cov nqi tsim tawm los ntawm chav tsev dhau los tom qab txhua qhov kev xav thiab ua ntej kev luam tawm tom ntej kom tsis txhob muaj tus lej splattering thiab sau npe tsis raug ntawm CI flexographic tshuab luam ntawv.
● Ua ntej Rewinding Unit: Xyuas kom cov khoom nyob rau hauv ib qho nruab nrab lub sij hawm rewinding los tiv thaiv misalignment los yog thaiv.
3.Material and Process Optimization:
● Kev xaiv cov khoom siv: Xaiv cov substrates uas muaj cov khoom tiv thaiv zoo li qub los yog cov khoom nto-kho rau kev ua haujlwm zoo li qub, lossis cov substrates nrog cov conductivity zoo uas phim cov txheej txheem luam ntawv flexography.
●Grounding System: Xyuas kom lub ci flexo xovxwm muaj ib qho kev qhia thiab txhim khu kev qha hauv av. Tag nrho cov hlau chais thiab cov khoom siv thav duab yuav tsum tau ua kom zoo hauv av kom muaj txoj hauv kev zoo rau kev tso tawm zoo li qub.
4.Routine Maintenance and Monitoring: Khaws cov kev taw qhia cov menyuam thiab cov bearings huv si thiab ua haujlwm zoo kom tsis txhob muaj kev sib txhuam tsis zoo vim hluav taws xob zoo li qub.
Xaus
Electrostatic tswj rau ci flexo rinting xovxwm yog ib qhov systematic project uas tsis tuaj yeem daws tau los ntawm ib txoj kev. Nws yuav tsum muaj kev qhia dav dav thoob plaws plaub theem: kev tswj hwm ib puag ncig, kev tshem tawm kom nquag plias, xaiv cov khoom siv, thiab kev saib xyuas cov cuab yeej siv, tsim kom muaj ntau txheej txheej tiv thaiv. Tackling hluav taws xob zoo li qub scientifically yog qhov tseem ceeb rau kev txhawb nqa kev luam ntawv zoo thiab slashing pov tseg. Txoj hauv kev no txo qis qis qis thiab ua kom muaj txiaj ntsig zoo, ruaj khov, thiab ua haujlwm zoo.
