Flexographic luam ntawv tsis xws luag: Pinholing ua thiab cov kev daws teeb meem

Taw qhia rau Flexographic Luam Ntawv thiab Pinhoce

Dab tsi yog flexographic luam ntawv?

Flexographic Printing yog lub npe nrov luam qauv siv hauv kev lag luam ntim khoom. Nws siv cov ntawv luam tawm saj nyem los hloov mem kua rau ntau yam khoom xws li ntawv, yas, thiab ntawv ci. Cov txheej txheem no paub txog nws cov versatility thiab muaj peev xwm ua cov ntawv luam zoo sai thiab muaj txiaj ntsig.

Vim li cas Flexographic Printing tseem ceeb?

Niaj hnub no kev sib tw ua lag luam niaj hnub no, zoo nkauj ntim yog qhov tseem ceeb rau cov neeg siv khoom siv. Flexographic cov ntawv luam ntawv pab tsim kev pom kev txaus siab thiab ntim ntim ruaj ruaj uas sawv ntsug ntawm cov khw muag khoom. Nws yog qhov zoo tagnrho rau cov khoom loj-teev ntau vim nws qhov nrawm thiab ua tau zoo.

Dab tsi yog pinholing?

Pinholing yog hais txog cov me me uas tsis pom zoo me me uas tshwm rau ntawm lub substrate thaum lub tshuab luam ntawv. Cov pob no zoo li lub qhov me me thiab cuam tshuam txuas ntxiv ntawm thaj chaw luam tawm. Pinholing yog ib qho tsis xws luag nyob rau hauv flexographic luam ntawv thiab muaj peev xwm cuam tshuam loj tshaj luam ntawv zoo.

Cuam tshuam ntawm pinholing rau luam tau zoo

Pinning cuam tshuam qhov pom tau pom ntawm cov ntaub ntawv luam tawm los ntawm kev tsim cov khoob hauv thaj chaw muaj xim. Qhov no tuaj yeem txo cov zoo tag nrho thiab ua rau lub ntim zoo saib tsis tau. Nws yog tshwj xeeb yog pom hauv cov xim muaj xim loj thiab tuaj yeem cuam tshuam cov neeg siv khoom nkag siab thiab yuav cov kev txiav txim siab.

Qhov tseem ceeb ntawm kev daws cov nyiaj cheb

Nkag siab thiab hais txog qhov ua rau ntawm pickholing yog qhov tseem ceeb rau kev tswj cov siab ua kom siab zoo. Los ntawm kev txheeb xyuas thiab daws qhov tsis xws luag no, luam ntawv tuaj yeem txhim kho kev pom ntawm lawv cov khoom lag luam thiab zam cov nqi qis lossis rov ua dua.

Dab tsi yog pinholing hauv flexographic luam ntawv?

Kev txhais thiab pom cov yam ntxwv

Pinhoce yog tus cwj pwm los ntawm cov pob txha tsis tau ntawm lub substrate. Cov pob no feem ntau tsis xwm yeem hauv cov duab thiab qhov loj me, zoo li pinholes. Lawv cuam tshuam rau kev sib txawv ntawm thaj chaw luam tawm thiab yog qhov tshwj xeeb yog pom hauv cov xim muaj xim.

Yuav ua li cas pinholing cuam tshuam rau luam tawm zoo

Pinholing txo cov ntom ntom thiab xim vibranch ntawm cov ntaub ntawv luam tawm. Nws tsim cov tsos tsis sib xws uas tuaj yeem ua rau lub ntim zoo saib tsis tau. Qhov kev tsis haum no yog cov teeb meem tshwj xeeb hauv kev ntim cov ntawv thov uas pom kev pom kev pom yog qhov tseem ceeb rau cov neeg siv khoom thov.

Kev loj hlob ntawm cov pinholing hauv flexographic luam ntawv

Pinholing yog ib qho teeb meem tshwm sim hauv flexographic luam ntawv vim zoo li number cask kom qhuav nrawm, substrate nto zoo, thiab cov cuab yeej siv. Nws tshwm sim thaum number case tsis tau npog tag nrho cov substrate, tawm hauv v meids lossis qhov. Kev tu lwm tus saib xyuas kom zoo thiab kev kho kom haum tuaj yeem pab txo qis qhov tshwm sim.

Ua rau ntawm pinholing hauv flexographic luam ntawv

Ink-ntsig txog teeb meem

• Kev ziab khaub noom nrawm nrawm ntawm cov inks : thaum inks qhuav sai, lawv yuav tsis tau npog tag nrho cov substrate, ua rau pinhoing. Qhov no tuaj yeem tshwm sim los ntawm kev kub siab lossis tsis raug cai tso rau hauv.

• Siab viscosity ntawm inks : inks uas yog tuab dhau yuav ua rau kev pab them tsis ncaj thiab kev hloov pauv tsis zoo mus rau substrate, tsim pinholes.

• Muaj cov hnoos qeev lossis cov lus hauv inks : impurities nyob rau hauv tus number case tuaj yeem cuam tshuam kev luam ntawv thiab ua rau cov veeps luam me me hauv thaj chaw luam tawm.

Phaj-ntsig txog teeb meem

• Tsis xwm yeem lossis kev puas tsuaj rau ntawm phaj : puas lossis tsis muaj cov ntawv luam tawm tuaj yeem tiv thaiv cov ntxhiab tsw zoo, ua rau muaj kev sib hloov.

• Qhov tob tsis tsim nyog dot qhov tob lossis cov duab ntawm cov ntawv luam tawm : Dots uas yog cov khaub ncaws ntiav dhau los yog tsis muaj cov number case tsis txaus, ua rau tsis muaj kev pab kom txaus, uas ua rau tsis tiav kev pab them nyiaj.

Cov Khoom Siv Hluav Taws Xob cuam tshuam

• Kev xav tsis ncaj : tsis sib xws siab nruab nrab ntawm lub tshuab luam ntawv thiab substrate tuaj yeem ua rau qee thaj chaw kom tau txais cov number casces, tsim pinholes.

• Cov khoom tsis raug ntawm cov khoom siv kom qhuav : Cov khoom siv ziab uas tau teeb tsa dhau los lossis qis qis tuaj yeem cuam tshuam tsis tau kom qhuav thiab hloov pauv, ua rau pinhoing.

Substrate-ntsig txog teeb meem

• Mismatch ntawm substrate nto nro thiab number cas : Yog hais tias lub substrate lub nro yog tsis sib xws, tus number case yuav tsis kis tusyees, uas ua rau pinholes.

• Muaj cov hmoov av, roj, lossis lwm yam paug ntawm cov chaw paug : cov paug ntawm cov number case tuaj yeem tiv thaiv kom tsis txhob muaj qhov zoo, ua rau cov lus pov thawj rau hauv thaj chaw luam tawm.

Kev daws rau Pinholing hauv Flexographic Printing

Kho cov tshuaj mem khoom

• Hloov Ik formulations : kho cov kua mem ua qauv kom ua tiav cov kev ua kom qhuav qhov nrawm nrawm thiab viscosity. Qhov no ua kom pom tseeb qhov kev hloov mem tes kom raug thiab txo qhov tshwm sim ntawm pinholing.

• Ntxiv retarders lossis thinners : ntxiv retarders lossis nyias tuaj yeem qeeb ncau ziab qhuav, tiv thaiv nws kom qhuav sai thiab ua rau pinholes.

• Ua kom muaj kev coj dawb huv : Siv cov innks zoo thiab ua kom lawv tsis muaj kuab. Nquag huv kua mem kua kuab thiab tus me nyuam cov tshuab los tswj cov number case purity.

Txhim kho cov paib luam ntawv

• Soj ntsuam thiab hloov cov paib puas : nquag tshuaj xyuas cov ntawv luam tawm rau kev puas tsuaj lossis tsis xwm yeem. Hloov cov phaj uas puas los ua kom ntseeg tau txawm tias tsis tuaj yeem hloov.

• Xaiv cov khoom siv phaj tsim nyog : xaiv cov ntaub ntawv phaj uas muab cov kua mem kua dawb thiab tiv taus o thiab puas. Txiav txim siab siv cov kuab tshuaj-tiv thaiv Elastomer Tsho rau kev ua tau zoo dua.

Kev Txij Nkawm Kev Tu Thiab Kho

• Kev kuaj xyuas thiab ntsuas qhov xav tau siab : tsis tu ncua thiab ntsuas ntsuas lub tswv yim ntawm lub tshuab luam ntawv thiab substrate. Xyuas kom meej xwm rau kev hloov kho tus ntxhiab.

• Kho cov khoom kom qhuav : Hloov cov khoom kom qhuav kom phim cov number case kom qhuav. Zam kev nqis uas muaj siab dhau los yog qis dhau, uas tuaj yeem cuam tshuam tsis tau taub hau thiab hloov chaw.

Substrate ua ntej kev kho mob

• Kev siv cov kev kho kom ncaj : kho cov txheej txheem nrog cov kev kho kom nto xws li Corona lossis nplaim hluav taws xob kev kho kom zoo nkauj thiab txhim kho cov kua zaub.

• Ua kom cov substrates huv : huv si substtrates kom huv si ua ntej luam tawm plua plav, roj, thiab lwm yam paug, thiab lwm yam paug tsis tau.

Ib puag ncig Tswj ntsuas kev ntsuas

• Kev tswj hwm qhov kub thiab cov av noo : tswj kom sov thiab cov av noo hauv cov num luam yeeb kom tiv thaiv kom qhuav nrawm lossis dhau los ua viscous heev.

• Tsis tshua muaj hluav taws xob zoo li qub : Txo cov hluav taws xob zoo li qub nyob rau hauv kev luam ntawv ib puag ncig kom tiv thaiv cov plua plav, uas tuaj yeem ua rau pinhoing. Siv cov khoom siv anti-zoo li qub thiab tswj cov av noo kom zoo.

Cov ntsiab lus ntawm qhov tseem ceeb ua rau thiab cov kev daws teeb meem rau pickholing

Pinholing yog ib qho tsis xws luag nyob rau hauv flexographic luam ntawv uas tshwm sim thaum inks tsis them tag nrho cov substrate, tawm ntawm cov pob me me uas sib dhos. Lub ntsiab ua rau muaj kev sib tw yog:

• Ink ntsig txog cov teeb meem : nrawm ziab nrawm, siab viscosity, lossis impurities nyob rau hauv number case.

• Phaj ntsig txog cov teeb meem : puas los yog cov paib luam ntawv tsis xwm yeem.

• Cov cuab yeej cuam tshuam ntsig txog cov cuab yeej : tsis sib xws siab los yog tsis muaj kev cuam tshuam cov khoom siv ziab.

• Substrate-cuam tshuam cov teeb meem : cov kev tsis sib haum xeeb saum npoo lossis paug rau ntawm substrate.

Qhov tseem ceeb ntawm Kev Tiv Thaiv Kev Sib Tw Tag Nrho

Oactentially hais txog pinhocing yog qhov tseem ceeb rau kev tswj hwm siab zoo thiab txo qis qis. Kev tu tsis tu ncua, tshuaj mem dej kom raug, thiab substrate kev kho mob tuaj yeem pab tiv thaiv qhov xwm txheej no thiab ua kom pom tseeb zoo ib yam nkaus.

Outlook on nce qib hauv Flexographic Printing Tshuab

Kev nce qib hauv cov tshuab luam ntawv hauv flexographic tshuab luam ntawv txuas ntxiv txhim kho kev ua kom zoo. Kev nrhav kev tsim qauv, luam tawm cov paib, thiab cov cuab yeej siv thiab cov cuab yeej tsim qauv yog pab cov tshuab luam ntawv ua tiav cov txiaj ntsig zoo dua nrog tsawg dua. Los ntawm kev hloov kho tshiab ntawm cov kev txhim kho no, cov tshuab luam ntawv tuaj yeem txhim kho lawv cov txheej txheem thiab xa cov kev siv cov kev daws teeb meem zoo dua.
