Ua kom tiav cov teeb meem ntawm tus cwj mem ntawm Gift Paper Boxes printing, tag nrho ntawm cuaj kauj ruam

Ua kom tiav cov teeb meem ntawm tus cwj mem ntawm Gift Paper Boxes printing, tag nrho ntawm cuaj kauj ruam

Ink plays an important role in Gift Paper Boxes printing. But in some flexible packaging factories, ink is one of the factors that "love to make trouble". In fact, maybe it's not the ink's fault, but the operation. The editor makes an inventory of printing faults and solutions caused by ink for reference.

1. Txiav txim tus scraper adaptability thiab transferability ntawm tus number case

Tus number case ntawm gravure luam ntawv phaj lub tog raj kheej tsis huv, thiab tus number case hauv lub tshuab luam ntawv number case yog tuab, thiab cov ntawv luam tawm yuav tsis muaj xim, dai qias neeg, khiav tawm number case, riam hlau, riam kab thiab lwm yam. Staining thiab number case khiav ntawm cov ntawv luam tawm yog cuam tshuam nrog kev hloov ntawm tus number case viscosity. Lub sij hawm luv luv - lub sij hawm txheej txheej tshwm sim ntawm tus number case tuaj yeem ua rau smearing, thiab tus number case khiav phenomenon yuav tshwm sim thaum tus number case viscosity siab, tab sis nws yog ze ze rau qhov raug thiab tsim nyog ntawm lub kaum sab xis thiab siab ntawm cov cuab yeej scraper. . .

Nws tsuas yog thaum tus number case ntawm tag nrho cov ntawv luam ntawv lub tog raj kheej tsis tuaj yeem so huv, thiab qhov chaw tsis tuaj yeem ntxuav los ntawm nias nrog ntiv tes lossis hloov tus cwj mem tshiab, nws yuav muaj teeb meem nrog tus number case. Yog tias nws tuaj yeem ntxuav tau tom qab hloov tus cwj mem tshiab, muaj teeb meem nrog cov thinner ntxiv rau hauv tus number case.

Txoj kev daws teeb meem: hloov tus number case los yog nyias, thiab kho cov scraper.

2. Kev tshuaj xyuas ntawm kev luam ntawv substrate (yas zaj duab xis)

Yog hais tias tus number case muaj phenomena xws li ploj lawm printing, dawb me ntsis, txiv kab ntxwv tev, thiab adhesion tsis zoo, nws yog ib qho tsim nyog yuav tau kuaj xyuas qhov nro thiab hluav taws xob zoo li qub ntawm lub tshuab luam ntawv substrate. Yog hais tias qhov nro ntawm lub tshuab luam ntawv substrate qis dua 35dyn, qhov adhesion ntawm tus number case yuav tsis zoo, thiab cov txiv kab ntxwv tev, number case thiab number case whiskers yuav tshwm sim nyob rau hauv lub static hluav taws xob sib dhos.

Kev daws: Kev kho deg ntawm lub tshuab luam ntawv substrate, nruab cov cuab yeej tshem tawm zoo li qub ntawm qhov cuam tshuam ntawm lub tshuab luam ntawv, ua kom cov av noo hauv chaw ua haujlwm, thiab kho qhov ziab nrawm ntawm tus number case nrog qeeb - ziab hnyav. Yog tias tus number case luam ntawv yog thinned, cov nyhuv ntawm kev ua kom nrawm nrawm yuav zoo dua.

3. Purity thiab tsis hnov ​​tsw tshuaj xyuas ntawm diluent

Yog hais tias lub purity ntawm diluent los ntawm tus thawj number case mus rau diluted number case yog tsis zoo, cov kuab residue ntawm cov ntaub ntawv luam tawm yuav nce, thiab tej zaum kuj yuav muaj residual tsw ntawm cov luam ntawv. Tshawb xyuas qhov purity ntawm cov kuab tshuaj ua ntej. Txoj kev sim yooj yim yog: rub ib daim ntawv dawb 8cm dav thiab muab tso rau hauv cov kuab tshuaj kom ntub nws, ces muab nws tawm thiab yoj nws nrog me ntsis quab yuam kom saib xyuas qhov ziab ceev ntawm cov kuab tshuaj ntawm daim ntawv dawb los yog seb nws hloov xim, thiab tom qab ntawd Smell cov kab dawb rau cov ntxhiab tsw seem.

Thaum daim ntawv dawb yog yoj rau 8-15 zaug, nws yog ib txwm rau cov kuab tshuaj mus rau volatilize thiab qhuav. Yog tias nws tsis qhuav, qhov hnyav volatilization ceev yog qeeb, txwv tsis pub, volatilization ceev ceev. Cov kab dawb ntawm daim ntawv yog cov xim tsis muaj xim, tshwj tsis yog xeb hauv cov kuab tshuaj, qhia tias muaj teeb meem nrog cov kuab tshuaj. Yog tias muaj cov ntxhiab tsw seem tom qab cov kuab tshuaj evaporates, purity ntawm cov kuab tshuaj tsis txaus. Thawj tus number case thiab diluted number case tau muab khawb rau ntawm zaj duab xis thiab sim tom qab ziab.

Lub scraping residue ntawm tus thawj number case yog loj, thiab cov seem seem ntawm cov diluted number case yog me me, uas txhais tau hais tias nws yog ib txwm. Ntawm qhov tsis sib xws, muaj teeb meem nrog cov kuab tshuaj diluted. Yog tias cov qauv scraping ntawm tus number case qub muaj cov ntxhiab tsw, muaj teeb meem nrog tus number case. Yog tias koj hnov ​​​​tsw tsw ntxhiab tsw ntawm cov qauv ntawm cov kua nplaum diluted, cov kuab tshuaj siv hauv cov thinner tsis huv.

Kev daws: hloov tus number case los yog kho cov kuab tshuaj ntawm cov thinner.

4. Kev siv tus neeg saib xyuas kom qhuav qeeb

Lub qeeb- tus neeg ua kom qhuav hauv tus number case, lossis qeeb - ziab diluent siv nyob rau hauv lub tshuab luam ntawv yog tsis raug, uas yuav ua rau qhov tshwm sim ntawm tom (noj los yog yaj) xim nyob rau hauv lub luam ntawv, thiab cov Qhov tshwm sim ntawm kev ziab tsis tseeb lossis tiv thaiv - nplaum ntawm cov ntawv luam tawm.

Kev daws: Hloov cov mis diluent ntawm cov luam ntawv number case, kho cov kev ua kom qhuav ntawm cov luam ntawv number case, thiab txhim kho cov luam ntawv ceev.

5. Daim ntawv thov ntawm diluents nrog sib txawv piv

Qhov sib txawv ntawm tus cwj mem diluents hauv kev luam ntawv tuaj yeem kho qhov kev ua kom qhuav ntawm tus number case, xim concentration ntawm tus number case, thiab viscosity ntawm tus number case. Kho lub dryness ntawm tus number case yog qhov zoo los ua kom cov luam ntawv ceev thiab txhim kho qhov pom tseeb ntawm cov ntawv luam tawm.

Kho cov xim ceev ntawm tus number case tuaj yeem txo qhov siab ntawm embossing roj hmab cov menyuam los yog ua haujlwm ntawm tus number case scraper, uas muaj txiaj ntsig zoo rau kev txhim kho cov luam ntawv ceev. Kho cov viscosity ntawm cov luam ntawv number case yog tus yuam sij rau kev tswj tus nqi ntawm tus number case siv los yog ua kom haum rau cov luam ntawv ceev thiab chav tsev kub ntawm qhov chaw luam ntawv.

Txoj kev daws teeb meem yog: raws li kev luam ntawv ceev, qhov tob lossis cov kab uas ua rau ntawm lub tshuab luam ntawv phaj rau cov menyuam (cov menyuam) nruas, thiab chav tsev kub ntawm qhov chaw luam ntawv, npaj ib qho sai - ziab, nruab nrab{{ 1}} ziab, qeeb- ziab lossis ntxiv - qeeb- ziab kom qhuav.

6. Yuav siv li cas los ntawm siab viscosity mus rau tsawg viscosity

Lub tshuab luam ntawv nrawm nrawm, thiab cov ntawv luam ntawv phaj thiab cov ntawv tseem sib sib zog nqus. Nws yog ib qho tsim nyog yuav tsum tau siv high - viscosity printing number case, txwv tsis pub cov qauv ntawm cov ntawv luam tawm yuav ua rau cov dej ripples vim cov viscosity tsawg.

Kev luam ntawv nrawm nrawm, thiab cov ntawv luam ntawv phaj thiab cov ntawv yog qhov ntiav. Nws yuav tsum tau luam tawm nrog tsawg - viscosity number case. Txwv tsis pub, cov qauv luam ntawv yuav tsis txaus lossis ploj vim yog tus number case viscosity siab. Lub tshuab luam ntawv kuj tseem yog vim muaj tus number case viscosity siab. Loj, ua rau cov luam ntawv ceev tsis tuaj yeem qhib.

Kev daws yog siv cov diluents thiab diluents los kho cov viscosity ntawm cov luam ntawv number case.

7. Hauv kev siv cov xim pleev xim xim thiab cov xim hlau, siv cov cwj mem faib cov menyuam

Spot xim number case luam ntawv yuav tsum muaj xim zoo sib xws thiab xim xim, thiab tooj liab thiab kub hmoov hauv cov xim hlau yog yooj yim los nag, yog li nws yog ib qho tsim nyog yuav tsum siv tus number case faib cov menyuam hauv kev luam ntawv, thiab tus number case nplawm tus pas nrig yuav tsum muab tso rau hauv tus number case luam ntawv. tais.

Tsis tas li ntawd, nyob rau hauv kev siv cov xim xim number case, lub thinner yuav tsum tau siv ua ke nrog cov thinner, thiab nws tsis tsim nyog siv cov kuab tshuaj ib leeg los dilute nws. Hlau number case yuav tsum tsis txhob diluted nrog hnyav. Txoj kev raug yog ntxiv diluent los kho.

8. Kev siv thiab kev sib xyaw siv tsis yog - cov kuab tshuaj tseeb

Txawm hais tias qhov tsis yog - cov kuab tshuaj muaj tseeb tsis tuaj yeem yaj cov khoom sib txuas hauv tus cwj mem, nws tuaj yeem txo cov viscosity ntawm cov luam ntawv number case thiab txo qhov tshwm sim ntawm kev tom (noj lossis yaj) xim thaum luam ntawv.

9. Adhesion xeem ntawm cov khoom luam tawm

Muab daim kab xev rau ntawm daim ntawv luam, ua kom nws nrog koj cov ntiv tes, thiab ua kom nws nruj nreem khi rau ntawm daim ntawv luam, ces maj mam nqa nws ib nrab ntawm nws qhov ntev, ces maj mam nqa lwm ib nrab.

Qhov tsawg dua tus number case sticks los ntawm Gift Paper Boxes, qhov muaj zog adhesion ntawm tus number case ntawm Gift Paper Boxes yog, txwv tsis pub cov adhesion tsis zoo. Yog tias tus cwj mem ntawm lub thawv Khoom Plig yog daig los ntawm ntau dua 40 feem pua, nws txhais tau hais tias tus cwj mem luam ntawv ntawm lub thawv Khoom Plig muaj qhov tsis tsim nyog adhesion. .
