Thib tsib, yam cuam tshuam rau qhov zoo ntawm zaj duab xis
1. Sau tus lej cim ntawm txheej xwm
Hais txog cov ntawv khoom, cov lej cim, cov ink number plawg, cheeb tsam nrawm thiab luam tawm nrawm. Thaum cov ntawv luam tawm ntawm sab plag yog tuab thiab cov duab thaj loj loj, ntau cov ntaub ntawv cov hlab pas capillary qhov blocked, uas hinders tus nkag mus thiab diffusion ntawm cov nplaum, ua qhov teeb meem luam tawm thiab cov yas yeeb yaj kiab nyuaj rau kev sib koom tes, thiab delamination, foaming thiab zoo li yog nws tshwm sim.
2. Ambient humidity
Lub nruab nrab ntawm cov nplaum thiab cov yeeb yaj kiab thiab cov teeb meem luam tawm, cov dej ntsiab lus yog hloov raws li qhov txheeb ze ntawm huab cua hloov. Humidity-sensitive prints yuav ua rau muaj kev ntxhov siab vim muaj kev hloov hauv seem. Piv txwv li, qhov ntev ntawm qhov sib piv ntawm qhov teeb meem ntawm cov ntawv luam tawm yog 0.5%, thiab cov cua kub ntev hauv BOPP yog 4%. Yog hais tias dej haus ntawm qhov teeb meem ntawm cov ntawv luam tawm loj heev thiab qhov kev loj hlob tshwm sim, thiab qhov teeb meem sab hauv yog tshwm sim los ntawm qhov cua kub ntsws ntawm cov yeeb yaj kiab, cov khoom yeeb yaj kiab kuj yuav tawg, ntsws, thiab ua ke. Tsis muaj zog. Tsis tas li ntawd, nyob rau hauv ib qhov chaw siab dav heev, tus nqi nruab nrab ntawm cov khoom tsim tawm kuj yuav hloov, thiab ib qho dej loj txaus ntawm cov cua nruab nrab yuav raug tso tawm ntawm qhov chaw thaum lub sij hawm kub nquag composing txoj kev, stagnating ntawm cov tsevneeg bonding , thiab ib qho uas ua ib qho tsis sib luag. tshwm sim.
Tshaj ntawd, qhov hloov ntawm cov khoom cua ntawm cov pa luam tawm ntawm cov pa luam yeeb (noo noo los ntawm cov pa nruab nrab los yog kev lim dej mus rau hauv cov cua nruab ntug) tshwm sim feem ntau ntawm ntug ntawm cov ntawv luam tawm, yog li ntawd nws tuaj yeem tsim ntug los yog ib ntug nruj tsis yooj yim tsim zoo nrog zaj duab xis nyob rau hauv lub kub xovxwm composite. Lub wrinkles yog ua los ntawm cov tsevneeg, yog li ntawd cov khoom yuav tsis tau nqa tawm smoothly.
3. Kub tswj
Cua kub tuaj yeem muag cov yeeb yaj kiab thiab daim ntawv cog lus rau cov yas yeeb yaj kiab. Txawm li cas los, qhov kub yog siab dhau lawm, zaj duab xis yog ib qho yooj yim mus ua txhaum, uas cuam tshuam qhov zoo ntawm qhov khoom. Yog li ntawd, kev ntsuas xws li kiv cua txias thiab xa tawm cua sov hlau yuav tsum tau saws.
Rau, rau txoj kev loj hlob ntsuab ntawm yas zaj duab xis
Daim ntawv tom qab zaj yeeb yaj kiab yog qhov tsis zoo thiab ua rau muaj kuab paug dawb, thiab tshuaj lom neeg xws li tshuaj toluene thiab dej yog lub sij hawm thaum txheej txheem yeeb yaj kiab, uas ua rau tib neeg txoj kev noj qab haus huv. Niaj hnub no, tawm suab "tiv thaiv ib puag ncig thiab tiv thaiv kev pabcuam", txheej txheem yeeb yaj kiab txheej txheej tau raug tshem tawm hauv Tebchaws Europe thiab Tebchaws Meskas, thiab European thiab Tebchaws Asmeskas tseem tsis kam xa cov ntaub ntawv ntim khoom nrog cov yas yeeb yaj kiab. Txawm hais tias muaj dej ntim zaj dab neeg thiab cov txheej txheem kub-txheej ua ntej txheej txheem txheej txheem yas txheej yas, cov qub tseem daws tsis tau qhov teeb meem uas cov luam yeeb yaj luam yuav tsis raug degraded thiab tsis tuaj yeem siv tau. Lub tom kawg yuav tsum tau muaj qhov loj ntawm cov hluav taws kub hauv cov txheej txheem ntau lawm thiab muab pov tseg. Cov khoom yuav tsum tau muab cais tawm hauv ntawv thiab yas ntawm 60 ° C, thiab tus nqi yog siab.
Nrog kev txhim kho ntawm kev tshaj tawm, cov tshiab thiab kev ua haujlwm tau zoo yuav tshem tawm cov txheej txheem qub, kom cov txheej txheem ua yeeb yam yuav muaj kev hloov zoo. "Non-toxic, harmless, thiab environmentally friendly" lawm ua qhov kev tsis pom zoo ntawm kev ua yeeb yaj kiab txheej txheem. Tsis tas li ntawd, qhov txheej txheem glazing yog vim li no optimistic. Glazing yog ib txoj kev los ntawm txheej, txau lossis luam tawm ntxiv kom tsis muaj xim tsis tshua xim rau ntawm qhov teeb meem ntawm cov ntawv luam tawm, uas yog, glazing roj. Tom qab calendering thiab ziab, glossiness ntawm daim npog ntawm cov ntawv luam tawm yog nce, thiab qhov nruj kuj zoo tuaj. Tom qab lub ci ntsa iab, cov khib nyiab tawm tuaj yeem siv tau los sis siv tau los ntawm nws tus kheej, thiab tsis ua rau thaj chaw tsis zoo. Yog li, glazing yog ib tug ua tshuab nrog kev loj hlob muaj peev xwm, thiab nws yog ib qho ua kom maj mam nyob hauv lub txheej txheem kev lag luam txheej txheem. Txawm tias cov cav tov ua rau siv cov roj ntsa glazing thiab cawv pleev xim rau lub lag luam yog toluene thiab cawv, feem ntau, uas muaj teeb meem rau tib neeg lub cev thiab tsis zoo rau kev tiv thaiv ib puag ncig, dej glazing tau maj mam ua lub hauv paus ntawm txheej txheem glazing. Dej raws UV glazing txheej txheem uas tau tsim kom deb li deb yog ib qho chaw zoo nkauj rau tus phooj ywg glazing thiab txoj kev loj hlob ntawm cov txheej txheem glazing yav tom ntej.
