Nyob rau hauv xyoo tsis ntev los, zaj duab xis yog yeej ib tug ua ntej coated zaj duab xis. Txij li thaum lub sij hawm siv tsis ntev thiab muaj ntau yam teeb meem, raws li tus txheej txheem xyaum, qhov zoo ntawm cov zaj duab xis precoat yog kub thiab siab. Peb lub hauv paus ntawm kev khiav, yog li qhov tseeb ntawm kev sib raug zoo ntawm peb qhov tseem ceeb los xyuas qhov zoo ntawm cov zaj duab xis precoat thiab cov kev cuam tshuam rau kev tsim cov txheej txheem ntxiv.
Ntawv txheej yas yog qhov kev tshwm sim ntawm lub cev sib thooj ntawm thermal compression. Kub, siab thiab ceev yog qhov peb yam tseem ceeb los mus ua kom tau qhov sib txuam ntawm lub cev. Tuav tes tuav txoj kev sib raug zoo ntawm no peb yog tus yuam sij rau txoj kev khiav lag luam.
Kub: Nws yog thawj qhov tseem ceeb ntawm zaj duab xis. Lub nplaum rau lub txheej txheem ua ntej txheej txheem yog kub yaj nplaum. Qhov kub txiav txim siab lub melting lub xeev ntawm kub qhuav nplaum, uas txiav txim siab lub theem kev ua tau zoo ntawm lub kub qhuav nplaum thiab txiav txim siab lub molecular kev coj ntawm lub kub qhuav nplaum. BOPP zaj duab xis, luam tawm cim lej txheej, daim ntawv substrate thiab lwm yam peb lub tshuab diffusion muaj peev xwm, tab sis kuj txiav txim siab lub crystallinity ntawm kub yaj nplaum, tsuas yog qhov tseeb tswj ntawm qhov kub ntawm thaj chaw ua hauj lwm, thiaj li ua rau cov zaj duab xis precoat tau cov cua sov hauv zaj duab xis Cov roj hmab txheej txheem yog ua kom tiav rau hauv lub xeev uas khiav ceev, thiab tau tsim cov dej ntub kom ntub ntub tawm ntawm qhov teeb meem ntawm cov ntawv luam, thiab kom muaj kev kho sai tom qab sib xyaws. Cov khoom laminated yog tsim kom muaj lub tsob pav ca, zoo nkauj txaus, muaj ib qhov zoo ntawm melting ntawm roj hmab txheej, thiab tsis muaj crease. Thiab tau tev tawm ntawm tus number case. Kev tswj kev kub ntawm txoj kev ua kom zoo li qub yuav cuam tshuam thiab txiav txim siab thermal erosion ntawm zaj duab xis los daws qhov kev hloov hauv tshav kub thiab qhov tsis kam ua kom sov dua. Vim li no, kev kub siab tswj hwm yog thawj qhov tseem ceeb rau precoat film txheej. Raws li peb xyaum. Kev ntsuas kub yog qhov zoo tshaj nyob rau thaj tsam ntawm 80 txog 100 C.
Siab: Qhov tsim nyog yuav tsum tau siv thaum uas tswj kev ntsuas kub, vim tias cov ntawv saum npoo tsis yog lub hauv paus. Tsuas yog nyob rau hauv qhov kev txiav txim siab ntawm kev kub ntxhov, kub qhuav nplaum hauv lub xeev khov kho yuav nyob hauv tus txheej txheem ntawm kev tsav tsheb tawm ntawm huab cua ntawm qhov teeb meem luam tawm. Ntub ntub saum npoo ntawm daim ntawv sau. Muab cov khoom sib colloidal rau cov ink number ntawm daim ntawv, cov diffusion ntawm daim ntawv lwv, dislocation, thiab ua tau zoo adhesion, ua kom tiav cov kev pabcuam ntawm tagnrho cov nplai ntawm cov ntawv luam tawm, yog li ntawd cov teeb meem luam ntawv nce mus ib kaj, tsis muaj huab , lub roj hmab txheej yog theem, tsis muaj crease Cov kev ua kom tsevneeg muaj kev zoo, thiab qhov siab yuav ua rau kom muaj cov pob txha uas tsis muaj pob zeb, kom lub tshuab thermoplastic ntawm lub pob zeb kub nplaum yuav tau qhia tawm. Yuav kom ntseeg tau tias cov khoom yeeb yaj duab ntxiv tom qab kev sib xyaw kom haum. Nws muaj zog tuaj yeem ua rau ntau lub cev nqaij daim tawv, kev cuam tshuam thiab lwm yam teebmeem. (xws li kev quab yuam, bronze, kub yaj kua nplaum, thiab lwm yam) kom ua tiav ib txoj kev sib koom tes ntawm cov qauv sab hauv thiab sab nraud ntawm lub luam tawm.
Kev Ceev: Daim ntawv overlay yog ib qho kev txav siab hauv kev sib txig. Kev ceev ntawm kev txav txiav txim rau lub sij hawm thaum lub sij hawm uas daim ntawv-yas hluav taws nyob ntawm lub thermocompression ua hauj lwm nruab nrab, thiab tseem yuav txiav txim siab qhov kub thiab qhov siab ntawm cov tswv yim laminator thiab kev koom tes ntawm cov ntawv thiab yas hauv cov txheej txheem tsim tawm. Kev nqis tes ua qhov tseeb. Thaum twg cov naam thiab qhov kub siab txias. Qhov kev hloov ntawm kev ceev yuav hloov cov nyhuv txheej, thiab vim yog lub siab tshaj plaws ntawm kev kub thiab qhov kev txwv ntawm qhov kev pabcuam, nws yuav tsuas hloov los ntawm cov kev taw qhia tsawg tshaj li tus nqi muaj nqis, thiab nrog lub zog ntawm kev ceev, qhov siab yuav txo tau obviously , thiab cov kub pressing quab yuam yuav tsis kam. Ua kom cov nyhuv ua ke dua. Khiav dhau sai heev. Kev cog lus tsis ruaj khov. Yuav muaj huab, qeeb dhau los ua tsis tau zoo. Txawm tias bubbling. Li ntawd, tus compound sau ntawm kev ceev. 4. Txiav txim siab txog lub sij hawm ua zaj yeeb yaj kiab thiab daim ntawv luam kom tiav tsev neeg. Raws li peb kev paub, kev dav dav dav tswj yog tsim rau txog 10-20 nplooj ntawv ntawm cov ntawv hauv ib feeb. (Qhov ceev ntawm lub tshuab siv cov tshuab hauv tshuab raj yog me me vim muaj kev kub nyhav rau cov menyuam.
Qhov tseeb qhov nqi ntawm peb yam tseem ceeb ntawm kev kub, siab thiab kev ceev muaj qee yam. Vim qhov txawv ntawm cov khoom. Qhov no yuav tsum tau kom peb nrhiav tau tus nqi zoo tshaj plaws hauv kev xyaum ua kom paub tseeb tias cov nyhuv ua ntej ntawm cov txheej txheem ua ntej thiab tsim kom muaj kev txhawb zog rau txoj kab qaum hau ntawm tus txheej txheem tom ntej uas tsis tas tawm hauv lub plhaub thiab tsis zoo. Cov txheej txheem ua ntej, yuav ua li cas thiaj tsim tau cov dejnum rau lwm tus txheej txheem (xws li kev quab yuam, kev sib tw, cov ntaub yas siv, thiab lwm yam) yog ib qho tseem ceeb uas peb yuav tsum xav txog thaum siv cov yeeb yaj kiab ua ntej. Thaum cov zaj yeeb yaj kiab ua ke nrog rau daim ntawv sau. Qhov txo qis yog 80C thiab lub siab txwv yog 100C. Intuitively, tom qab lub cev lub cev cais tawm ntawm cov xovxwm kub kub, qhov ci ci siab, tsis muaj huab, zoo flatness, thiab tsis muaj blistering. Nyob rau hauv xws li ib tug kub ntau, lub kub qhuav nplaum tau tag nrho tau txais kub tawm sab nraud mus rau sab hauv. Muaj nuj nqi, qhov hloov ntawm ntau cov ntaub ntawv raw hauv lub cev gel tuaj yeem ua tiav, thiab tag nrho cov roj hmab txheej tag nrho yog melted. Tsim kom muaj tseeb, ruaj khov, es tsis yog ib qho tsis txaus ntseeg, ntiav, tsis muaj zog lossis tsis pom kev zoo uas tsis khoov los yog rov ua haujlwm.
Thaum qhov txo qis kub yog qis me ntsis lawm, qhov ci ntawm cov khoom sib xyaw yuav txo. Thaum lub siab tshaj plaws ntawm kev kub kub yog me ntsis ntxiv, npuas uas tsis sib luag thiab muaj ntau daim duab raug hlawv rau ntawm qhov chaw ua si. (Qhov no tshwm sim yog tshwj xeeb pom nyob rau hauv lub tshuab laminating tshuab) cia li muaj cai tuav cheeb tsam ua haujlwm tseem ceeb ntawm cov zaj duab xis kub. Tsuas yog cov txuam zoo nkaus xwb yog qhov zoo, tab sis tseem kub kub colloid yog nyob ze ntawm qhov chaw kub ntawm qhov sib tw ntawm kev sib txuas. Lub solidification ntawm lub colloid yog ib qho nyuaj, yog li ntawd nws yuav tsis soften yooj yim thaum nws rov rhaub dua. Qhov tseeb kub tswj txoj kev rau lub lag luam ua hauj lwm yog kom txawj ua no finely. Cov naam kub yog ze heev rau qhov kev kub ntxhov sib txuam.
