Yuav ua li cas daws rov qab- Cov teeb meem nyob rau hauv dej-Raws li Screen Printing Inks

Los ntawm kev tsim txiaj ntawm lawv cov txiaj ntsig ib puag ncig, cov yam ntxwv ntawm kev nyab xeeb, thiab kev yooj yim ntawm kev tu, dej-raws li kev tshuaj ntsuam luam ntawv inks tau tshwm sim los ua qhov tseem ceeb hauv kev lag luam luam ntawv. Txawm li cas los xij, cov tuam txhab tsim khoom thiab cov khw luam ntawv tau sib zog ntev nrog kev sib tw tsis tu ncua: qhov tshwm sim hu ua "kev thaiv." Qhov no tshwm sim thaum cov ntaub ntawv luam tawm - tom qab tau muab tso ua ke lossis qhov txhab- ua raws li ib leeg, ua rau cov khoom tsis xws luag, xav tau kev rov ua dua tshiab, thiab txo qis kev tsim khoom.

 

 

1. Nkag siab Rov qab-Tswj rau hauv dej-Raws li Screen Printing Inks

 

 

 

 

Rov qab- nplaum yog hais txog qhov tsis xav tau adhesion ntawm cov ntaub ntawv luam tawm thaum lawv muab tso ua ke, dov, los yog khaws cia ua ntej tus cwj mem zaj duab xis tau kho tag nrho lossis ruaj khov. Qhov teeb meem no tshwj xeeb tshaj yog nyob rau hauvdej -raws li inks, qhov chaw ziab yog nyob ntawm cov dej evaporation ntau dua li cov kuab tshuaj flashing.

 

Cov yam ntxwv tseem ceeb ntawm Back-Sticking:

Cov ntaub ntawv luam tawm ua raws li kev sib tw

Tus cwj mem hloov los yog ghosting tshwm sim

Nto gloss puas lawm

Txo abrasion tsis kam

Cov khoom tsis lees paub hauv daim ntawv thov ntim

Yog vim li cas dej-Based Inks muaj ntau dua:

Piv rau cov kuab tshuaj-raws li inks, dej-raws li systems:

Muajqeeb kom qhuav tus nqi

Yog rhiab heev rauhumidity thiab kub

Xav taumeej formulation tshuav nyiaj li cas

Nyob ntawm hnyav heevtxheej txheem txheej txheem

Rov qab- sticking tsis yog los ntawm ib qho tseem ceeb tab sis feem ntau yog qhov tshwm sim ntawmntau- kev sib cuam tshuam sib txawv, suav nrog kev tsim tus number case, luam ntawv tsim, ziab khaub ncaws, thiab cov khoom siv substrate.

 

2. Lub hauv paus ua rau rov qab -Sticking: Ink, Txheej txheem, thiab ib puag ncig

 

Nkag siab txog cov hauv paus hauv paus yog qhov tseem ceeb rau kev daws teeb meem zoo. Cov laj thawj no tuaj yeem muab faib ua peb qhov tseem ceeb:

2.1 Ink Quality thiab Formulation Issues

Tsawg- dej zoo-raws li inks yog ib qho ntawm cov laj thawj feem ntau rau rov qab - nplaum. Qee cov tuam txhab lag luam tseem ceeb txo tus nqi, ua rau:

Tsis txauszaj duab xis- ua cov ntsiab lus resin

Tsis zoo-zoostyrene -acrylic emulsions

Tsis txauswax additives rau kev tiv thaiv - thaiv

Tsis tsim nyogcoalescing tus neeg sawv cev sib npaug

Yog li ntawd, ink zaj duab xis:

Tseem tacky tom qab ziab

Tsis muaj hardness thiab abrasion kuj

Ua pov thawj tsis zoo nto plam

2.2 Printing Design and Process Factors

Cov xwm txheej luam ntawv ua lub luag haujlwm tseem ceeb:

Heavy number case deposition(thick number case txheej)

Multi- txheej txheej overprinting

pluagscreen mesh xaiv

Tsis tsim nyogink viscosity tswj

Cov xwm txheej no ua rau:

Ua kom qhuav qeeb

Uneven ink zaj duab xis tsim

Ua kom muaj peev xwm ntawm qhov adhesion

 

2.3 Tshuab ziab khaub ncaws thiab ib puag ncig tej yam kev mob

 

 

3. Cov kev daws teeb meem zoo los tiv thaiv rov qab-Tau

Txhawm rau tshem tawm rov qab- nplaum, yuav tsum muaj kev sib koom ua ke ntawm cov khoom siv, kev tswj cov txheej txheem, thiab cov khoom siv.

3.1 Optimize Ink Selection thiab Formulation
Xaiv lub siab - dej zoo- raws li cov inks uas muaj pov thawj ua tau zoo
Xyuas kom cov theem tsim nyog ntawm:

Coalescing agents (film integrity)
Ua haujlwm ze nrog cov neeg muag khoom los kho tus cwj mem rau:
PET, PVC, lossis ntawv substrates
Tej yam kev mob kom qhuav

Yog tias rov qab - nplaum yog tshwm sim los ntawm tus number case zoo, pom zoo hloov tam sim ntawd.

3.2 Tswj Ink Viscosity thiab Printing Parameters
Ua kom ruaj khov viscosity siv lub viscometer digital
Tsis txhob ntau tus number case thickness
Ua kom zoo:
Screen mesh suav
Squeegee siab
Kev luam ntawv ceev

Balanced parameters xyuas kom meej:

Uniform number case txheej
Kev ziab sai dua
Txo tackiness
3.3 Txhim kho kev ziab kom qhuav

Drying optimization yog qhov tseem ceeb:

Kho qhov cub kub raws li tus number case system
Synchronize kab nrawm nrog lub peev xwm ziab
Ua kom cua kub ncig
Txuas lub sij hawm ziab yog tias tsim nyog

Cov lus pom zoo:

Nruab qhov ntsuas kub ntsuas
Ua kev ntsuas kev ua haujlwm kom qhuav tsis tu ncua
Tsis txhob stacking ua ntej kom qhuav tag
3.4 Siv Kev Tiv Thaiv -Txoj Kev Tiv Thaiv
Ntxiv polyethylene wax slurry los txhim kho nto plam
Siv cov tshuaj tiv thaiv- thaiv cov hmoov (yog muaj)
Optimize stacking siab thiab cia tej yam kev mob

 

4. Rhiav kev tswj thiab txheej txheem optimization

 

Ib puag ncig zoo- tswj hwm qhov chaw tsim khoom tau txo qis kev pheej hmoo ntawm rov qab - nplaum.

4.1 Cov cuab yeej ruaj khov thiab tu

Kev ntxhov siab tsis raug tuaj yeem:

Nce kev sib cuag siab
Ua kom nrawm nrawm ntawm cov khaubncaws sab nraud povtseg
4.3 Environmental Control
Tswj cov av noo theem
Tsis txhob siab - qhov chaw noo noo
Siv cov dehumidifiers yog tias tsim nyog
4.4 Cov ntaub ntawv kaw tseg thiab txheej txheem txheej txheem
Cov ntaub ntawv:
Ink viscosity
Qhuav kub
Tshuab ceev
Tsim tus txheej txheem kev khiav hauj lwm (SOP)

Cov ntaub ntawv- tsav tsheb tswj xyuas kom meej:

Kev sib raug zoo
Kev daws teeb meem sai dua
Kev txhim kho tsis tu ncua

 

5. Kev coj ua zoo tshaj plaws thiab yav tom ntej Trends hauv dej-Raws li Ink Technology

 

5.1 Cov ntsiab lus zoo tshaj plaws

Txhawm rau tiv thaiv rov qab - ua kom zoo:

Siv cov ntawv zoo- zoo, zoo- cov ntawv sau
