Tus kws sau ntawv ntseeg hais tias tus qub yog tshwm sim los ntawm qhov muag qhov muag ntawm cov thermoplastic txiv maj phaub nyob rau hauv lub xauv kua los yog ntau qhov hnyuv qhuav hauv tus lej ntxiv uas nyob hauv cov ntawv luam tawm ntawm sab hauv. Lub tom kawg yog tshwm sim los ntawm kev siv tsis zoo los yog ntau siv cov dispersing aids hauv tus cwj pwm los yog cov tshuab muaj zog. Tsab xov xwm no yuav muab los tham hauv tsab xov xwm no, tsuas yog rau cov neeg ua haujlwm hauv kev lag luam.
1 Siv siab los daws qhov teebmeem ntawm kev ua tawm los ntawm ntu txheej thiab txheej nplaum dhau lo tuab.
Los ntawm kev siv lub tshuab luam ntawv thiab cov tshuab txheej txheem lub tshuab, qhov adhesion ntawm cov luam tawm ntawm cov ntawv luam tawm txheej duab xim thiab cov coated composite roj hmab txheej yuav raug zoo sib xws thiab tus number case thiab kua nplaum yuav khiav ceev los pab txhawb cov cwj mem. Cov txheej txheem ntawm lub cev thiab cov molecular diffusion thiab qhov hluav taws xob ntawm lub kua nplaum txhim khu lub zog ntawm daim tawv nqaij ntawm cov zauv rau lub substrate, kua nplaum thiab luam tawm cov cwj mem.
Ntawm chav kawm, lub siab yuav tsum tsis txhob deformed los ntawm tus cwj pwm zaj duab xis thiab cov kua nplaum xim. Uas yog hais tias, lub hom phiaj ntawm qhov kev xav ntawm lub zog kuj yog tshem tawm cov kua ntau los sis roj hmab kom txo cov thickness ntawm tus number case thiab cov txheej nplaum kom paub meej tias tag nrho cov lej txheej thiab cov txheej nplaum yog cov teeb thiab ntom, thiab tiv thaiv cov kab mob voids los ntawm ib feem ntawm tus lej lossis hauv qab kua nplaum. Tiv thaiv tau qee cov phev thiab cov kua nplaum ua ke los ntawm kev ua cov npuas vim yog qhov tawm ntawm cov cua sov thaum cov cua kub curing lossis txias thiab kho.
2 Kho cov teeb meem ntawm qhov nrig nrog lub tshuab fais fab.
Feem ntau, peb siv cov kev ntub dej tawg, UV ziab khaub ncaws, cov plaub hau txias los yog qhuav ziab hauv lub ntim thiab luam ntawv. Lub hom phiaj ntawm kev ziab yog ua kom cov kua evaporation hnyav nyob rau hauv tus number case thiab kua nplaum txhuas kom pab ua haujlwm ntawm tus cwj pwm xaj ua tus qauv tsim thiab lo lus sib xyaw ua ke. Nws kuj tso cai rau tus lej thiab kua nplaum los ntub dej ntawm lub npoo los pab nws lub diffusion, nkag mus thiab adsorption. Yog li no, cov phom sij thiab cov khoom siv muaj kuab zoo yuav tsum muaj cov tshuab txaus, qhov muag plooj, thiab lwm yam., Los txhawb cov kuab evaporation thiab evaporation. Cov phom dawb thiab tsis zoo tuaj yeem ua cov duab tso tawm tam sim ntawd tom qab luam ntawv thiab daim ntawv thov.
Lub sij hawm cua txias ntawm cov cua sov, tshuab raj, tshuab, ci, thiab lwm yam yog nyob ntawm cov evaporation tus nqi thiab evaporation tus nqi ntawm qhov hnyav, thaum UV yam nyob ntawm qhov kev siv lub teeb. Lub sij hawm yuav tsum tsis txhob ntev dhau los kom tsis txhob muaj zog thiab tua ntawm tus cuav puav thiab zaj duab xis. Lub adhesion tsis zoo, qhov tsevneeg tsis muaj zog thiab tsis pub dhau luv, yog li qhov hnyav cua txias, evaporation lossis cross-linking tsis txaus, ua rau cov neeg pluag adhesion ntawm tus number case thiab kua nplaum. Zaj duab xis zog yog txo.
Peb paub tias luam tawm thiab laminating tuaj yeem nqa nyob rau hauv chav tsev kub los yog hauv qab ntim hauv qab ntom, ultraviolet, cua sov, los kho cua txias, los yog cua kub thiab cua txias, los yog nruab nrab ntawm sab qaum teb thiab kub cev. txheej txheem hloov. Qhov no yog xaiv raws li txoj kev kho (laus) ntawm tus number case thiab cov kua nplaum. Hauv particular, nws yog scientific kom tshem tawm cov yeeb yaj kiab tom qab zaj yeeb yaj duab tsim ntawm tus cwj mem thiab qhov curing ntawm kua nplaum (tua).
3 Txhim kho qhov teeb meem ntawm kev ua theem ntawm tus lej thiab kua nplaum nrog ib tus neeg ntxoov ntxoo.
Kev xyaum qhia peb tias tsis muaj teeb meem li cas tus lej thiab cov kua nplaum hluavtaws kua nplaum yog lub qhov infiltration ntawm cov nplaum ntawm cov ntaub nplaum (substrate los substrate) ntawm tus cwj mem thiab cov kua nplaum kab ua ke yog ib qho yuav tsum ua ntej kom tau txais lub zog ntawm adhesion, tab sis lub ntsiab cov xwm txheej cuam tshuam rau cov zom feem ntau yog nws yog qhov yam ntxwv ntawm tus cwj pwm thiab cov kua nplaum, thiab ua raws li cov lus sib dhos, ua kom pom qhov sib txawv ntawm cov kab uas muaj adsorbed, thiab ntev npaum li cas.
Txhawm rau txhawm rau txhawm rau ua kom zoo ntawm cov thev naus laus zis thiab sib xyaw, cov khib nyiab loj, cov thawv ntim qis thiab cov khoom siv sib xyaw nrog cov khoom siv yuav tsum tau siv thaum xaiv cov hnab ntim hauv tshuab luam ntawv. Tus neeg saib xyuas sib txuas thiab tus neeg saib xyuas txuas nrog kuj yog xaiv raws li tus yam ntxwv ntawm tus number case thiab lub compound.
Vim tias inks thiab composites yog ntau yam kev sib faib ntawm cov organic thiab inorganic pigments, nruab nrab ntawm cov organic thiab inorganic fillers, nruab nrab ntawm pigments thiab fillers, ntawm fillers thiab khi (cov tawv nqaij), cov tawv thiab cov tshuaj solvents. Yuav muaj kev sib tw adsorption ntawm lawv, yog li nws yog qhov tsim nyog yuav tsum tau them sai sai rau qhov kev txiav txim ntawm kev ntxiv cov pigments, fillers, adsorbents ntawm lub npoo ntawm cov khoom, thiab cov adsorption ntawm tus number case, cov kua nplaum thiab txheej txheem.
Nws tuaj yeem paub los ntawm kev tawm tswv yim adsorption uas thinner lub txheej txheej txheej ntawm lub plhaub txheej thiab lub kua nplaum kab ntawm cov khoom luam tawm, lub zog ntawm lub zog thiab lub zog ua zog dua. Yog li no, cov lej thiab cov txheej nplaum yuav tsum ua nyias li txhij thaum uas kom ntseeg tau tias cov duab thaij yeeb yaj kiab cov yeeb yaj kiab tsis ploj los sis cov txheej txheej tsis yog hauv qab. Nws feem ntau yog xam tias cov thickness ntawm tus number case txheej thiab cov nplaum kab yuav tsum tau tswj kom tau 8-100 μm.
Yog hais tias tus npliag los ntawm lub binder los yog cov kua nplaum nyob rau hauv lub tshuab xaws kua loj heev, nws tsis yooj yim los ua cov pleev xim txheej, thiab nws kuj yog qhov tsis zoo rau kev nkag mus thiab cov diffusion ntawm cov ntawv luam tawm ntawm cov ntawv luam tawm ntawm lub luam substrate los yog kua nplaum.
Tsis tas li ntawd, lub zog qhov adhesion kuj tseem muaj feem xyuam rau cov teeb meem ntawm qhov chaw npau taws. Lub qhov tob hauv qhov tob rau hauv cov thauv los yog cov khaub ncaws zoo nkauj. Nws tsis yog ib qho chaw zoo nkauj nplaum. Tsuas yog muaj qee qhov kev sib tw ntawm cov kab mob qeeb tau qhov chaw adhesion yuav nce thiab xaj los yog sib xyaw
Mechanical "engagement" tshwm sim ntawm qhov kev tawm tsam.
Tau kawg, nws tsis paub meej tias nws yog ua tau kom ua tau zoo adhesion ntawm tus cwj mem los yog kua nplaum kab hluavtaws ntev li ntev li ntawm cov nplais ntawm lub substrate yog ntxhib. Vim hais tias qhov saum npoo heev los yog tsis ncaj ncees, cov yeeb yaj kiab adsorption ntawm tus number case thiab cov adhesion ntawm cov txheej txheem ua ke kuj tsis zoo. Cov teeb meem tuaj yeem tsim nyob rau hauv qhov chaw uas muaj qhov sib txuas ntawm lub substrate los sis cov ntawv luam tawm zaj duab xis yog qhov ntxhib dhau los, thiab cov teeb meem yuav ua rau tus number case los yog tus nplaum tsim kom nkag mus rau cov kev ua ntawm tsis adhering, thiab qhov no tsuas yog ua kom muaj kev nyuab siab kom txo tau cov number case thiab lub substrate, Lub adhesive adhesion lub zog ntawm lub composite nplaum rau lub luam tawm zaj duab xis zaj duab xis. Yog hais tias tus nqi ntawm cov zauv uas siv rau saum npoo saum toj no tsawg dua, cov ink number ntawm daim duab number yuav ploj, thiab cov kua nplaum yuav tsawg dhau los ua tus yeeb yam, uas yuav tau txo cov zog ntawm cov zaj duab xis .
4 Txav qhov porosity saum npoo ntawm cov substrate nrog kua number case thiab kua nplaum ua kua.
Ib co substrates (nrog rau cov ntawv luam tawm zaj duab xis saum npoo av), muaj ntau qhov qhib pores uas pom tsis tau rau qhov muag liab qab. Yog hais tias tus cwj mem los yog cov kua nplaum los yog cov kua nplaum yuav kis tau rau phab ntsa pore, cov cua yuav tsum raug tso cai rau nkag mus rau hauv lub qhov hws thiab ua "khuav" hauv qhov. Ua kom zoo rau kev ua kom muaj zog.
Qhov tob ntawm tus cwj mem los ntawm cov kua nplaum los sis cov kua nplaum ntawm cov kua nplaum los ntawm lub qhov taub yog qhov sib thooj thiab qhov loj ntawm lub qhov hws, thiab qhov ua rau ntawm tus cwj pwm mus rau hauv lub substrate, qhov adhesion ntawm cov kua nplaum rau ntawm daim duab uas muaj cov ntawv luam tawm, fineness ntawm tus number case, lub qhov dej drilling thiab kev kho lub sij hawm ntawm cov kua nplaum, thiab cov zoo li. Lwm yam.
5 tswj tus lej dauv ntawm tus number case thiab cov kua nplaum sib xyaw thiab tus nqi ntawm cov yas lim.
Lub degree ntawm adhesion ntawm lub substrate thiab cov duab luam tau zoo kawg nkaus kev sib raug zoo nrog cov neeg kawm ntawv cov kev nkag mus ntawm cov cwj mem thiab cov txheej txheem ua ke. Yog li, qhov ntsuas no yuav tsum raug tswj.
Cov ntawv lo thiab cov duab thaij duab muaj kuab muaj qee tus neeg oligomers. Cov dej ntws ntawm cov khoom qis tsis zoo yog yooj yim heev txav tawm ntawm cov nplais ntawm lub substrate, los yog nws yooj yim mus seeb lub npoo ntawm cov ntawv luam tawm zaj duab xis, thiaj li hais tias qhov nro qhov nro txo. Yuav kom tiv thaiv thiab tshem tawm cov teebmeem no, lub npoo ntawm cov substrate thiab cov duab ntawm cov ntawv luam tawm ua ntej yuav tsum tau kho ua ntej lossis ua ntej luam ntawv.
Lub hom phiaj ntawm kev siv cov yas thaij hauv cov phev thiab cov kua nplaum sib tov ua ke yog qhov tseem ceeb kom tau txais kev tuav pov hwm ntawm tus cwj pwm ntim zaj duab xis thiab cov txheej txheem sib txuas ua ke. Qhov thib ob, tus cwj mem thiab cov roj hmab txuam nrog kev ceev ntiag tug muaj peev xwm txo cov kev sib txuas ntawm lub hauv paus, thiab ua rau lub zog muaj zog ntawm cov khoom siv los txhim kho lub zog ntawm adhesion. Txawm li cas los xij, thaum xaiv cov yas yas siv, cov khoom sib thooj ntawm cov yas thooj av nrog cov phom thiab cov khoom siv yuav tsum tau muab los xav, thiab yuav tsum tau muab cov khoom pov thawj pov tseg. Tus nqi ntawm cov yas siv yas siv hauv tshuaj thiab cov khoom siv feem ntau yuav tsum tswj kom tsawg dua 10%, uas yuav txo qhov adhesion ntawm cov khoom.
6 Siv tus nqi tsim nyog ntawm cov neeg muab tua txhawm rau ua kom tsis muaj tus lej thiab kua nplaum.
Kev siv cov ntaub fillers hauv luam ntawv hauv qab thiab cov kua nplaum hluavtaws tsis tsuas yog txuag cov ntaub ntawv, txo cov khoom siv, tab sis kuj txo qhov ntsws ntawm tus cwj mem thiab cov txheej txheem sib txuas, uas ua rau lub zog ntawm daim ntawv luam tawm zaj duab xis thiab cov nplaum .
Cov khaub thuas siv ntau yog: txo cov hmoov av los sis cov hmoov electrolytic hmoov, zinc oxide hmoov, ua kom muaj silica (dawb cov roj dub), hmoov kua txiv, calcium carbonate thiab cov zoo li.
Tsis tas li ntawd, yuav kom tiv thaiv cov teebmeem ntawm tus cwj pwm thiab cov kua nplaum kab ua ke, lawv lub sijhawm yuav tsum raug tswj.
Lub adhesion ntawm inks thiab composite adhesives nyhav rau qhov nce ntawm lub sij hawm cia. Qhov no yog vim hais tias tus number case thiab cov kua nplaum ua ke muaj ntu kev laus thaum lub sij hawm cia, thiab qhov tshwm sim kev hnyav dua yog tias raug huab cua. Vim li no, tus cwj mem thiab cov kua nplaum yuav tsum muab cia rau hauv ib lub taub ntim uas raug cais tawm ntawm huab cua, thiab lub sijhawm yuav tsum tsis txhob ntev ntev.
7 Siv lub qhov ntsuas kub kom zoo thiab txhim kho kev nplaum.
Qhov kev nce ntawm kev ua kom sov yog ua kom muaj peev xwm ntawm cov phom nyhuv nyob rau hauv tus number case thiab cov roj hmab hluav taws xob kom ua kom ceev ceev qhov sib zog, uas yog rau infiltration thiab adsorption, txhawb nqa adhesion thiab txhim kho tsev neeg muaj zog.
Ntawm chav kawm, qhov kub ntawm qhov sov tsis siab li sai tau. Nco ntsoov tsis txhob pub tshaj qhov ntsuas qhov kub (qhov kub thiab txias) ntawm qhov substrate kom tsis txhob deformation ntawm lub composite. Yog tias kub npaum li cas, tus number case thiab cov kua nplaum hluavtaws qis rau cov microvoides, thiab cov npuas yooj yim tsim kom txo tau qhov ua tau lub zog.
Ntawm qhov kev sib tw, lub zog ntawm daim ntawv luam ntawm lub hnab ntim ntawv luam tawm thiab cov khoom siv luam ntawv thiab cov ntawv luam tawm ntawm cov ntawv luam tawm nyhav nrog lub sijhawm tua, tab sis lub zog ntawm adhesion yuav tsis tuaj txog thaum muaj nqis. Nce dua. Kev kho kub thiab kev kho lub sijhawm muaj kev tiv thaiv. Hauv ntej, nce qhov kub thiab nce lub teeb zog thiab lub teeb siv lub zog yuav ua rau lub sijhawm tua kom tsawg. Yuav kom txo cov kub thiab txo qhov teeb meem ntawm lub teeb, nws yog ib qhov tsim nyog los ntev lub sij hawm kho.
8 Siv cov tshuaj tiv thaiv antistatic kom daws tau qhov teeb meem tsis yooj yim rau cov cwj pwm thiab tsis yooj yim siv cov kua nplaum.
Nyob rau hauv lub thev naus laus zis kev luam tshuab, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm cov tshuab luam ntawv tas mus li thiab tas mus li, vim kev sib txhuam ntawm cov substrate thiab cov tshuab luam ntawv thiab lub tshuab txheej, hluav taws xob muaj hluav taws xob, thiab qee cov substrates qhov hluav taws xob insulator yuav sau ntau dua, thiab nws tus cwj pwm tsis ntev los no yuav poob vim muaj hluav taws xob zoo, thiab cov duab ntawm cov duab luam yuav poob thiab cov kua nplaum yuav tsis yooj yim ua kom sib npaug, txawm tias deinked, degummed, thiab stripped.
