(1) Tus number case yuav tsum muaj adhesion zoo thiab txhua yam khoom
Txij li thaum cov tinplate prints nws thiaj li ua rau hauv cov kaus poom zaub mov, cov khoom ua si, cov thav ntawv hlau thiab cov thoob thiab cov kaus poom ntawm cov khoom siv tshuaj, lawv yuav tsum tau txiav, khoov thiab ncab, yog li cov luam ntawv number case yuav tsum muaj adhesion zoo rau tinplate thiab cov khoom siv kho tshuab. Txhawm rau txhim kho tus lej adhesion, tinplate yog thawj zaug hauv cov xim dawb ua ntej luam ntawv. Dawb yog lub hauv paus xim ntawm tag nrho cov duab thiab muaj siab brightness. Tom qab ntxiv lwm cov xim muaj zog, qhov ci ntsa iab ntawm txhua lub xim tuaj yeem txhim kho kom muaj xim xim.
(2) Kev xav tau rau tus cwj mem dawb
Qhov saum npoo ntawm tinplate yog nyiaj dawb (lossis daj), nrog cov xim hlau nplaum, ua ntej luam tawm cov duab xim, qhov saum npoo yuav tsum tau pleev xim dawb los yog luam tawm dawb, txwv los ntawm lub peev xwm ntawm tus cwj mem npog, lub tshuab monochrome feem ntau yuav tsum tau luam tawm dawb ob zaug, nws cov xim dawb tuaj yeem ncav cuag 75 feem pua. Raws li ib qho tseem ceeb qhia txog qhov zoo ntawm tinplate printing khoom, whiteness yuav tsum tau dawb number case kom muaj zoo adhesion nrog primer, thiab nws yuav tsis yellowish tom qab ntau high-temperature ci, thiab nws yuav tsis ploj tom qab high-temperature steaming. Priming tinplate tuaj yeem ua kom adhesion rau tinplate thiab muaj adhesion zoo rau cov number case dawb. Feem ntau siv primer yog epoxyamine-raws li hom, uas muaj cov yam ntxwv ntawm lub teeb xim, tsis muaj yellowing thiab tsis-aging tom qab ntau ci, thiab zoo saj zawg zog thiab cuam tshuam tsis kam.
(3) Kev xav tau rau xim number case
Xim inks luam nrog tinplate, ntxiv rau qee qhov kev tiv thaiv dej, kuj yuav tsum muaj lawv tus kheej tshwj xeeb. Txij li qhov saum npoo ntawm tinplate yog impermeable rau ya raws thiab cov kuab tshuaj, nws yuav tsum tau ci thiab qhuav, yog li nws cov number case yuav tsum tau kho kom sov. Cov kev xav tau siab rau pigment tinting zog thiab kav ntev. Ntxiv nrog rau qhov kev ua tau zoo ntawm cov ntawv luam tawm dav dav, cov luam ntawv hlau luam ntawv yuav tsum muaj cov yam ntxwv ntawm kev ua haujlwm kub, muaj zog number case zaj duab xis adhesion, cuam tshuam tsis kam, zoo hardness, ua noj ua haus tsis kam thiab lub teeb ua haujlwm raws li cov yam ntxwv ntawm cov hlau luam ntawv.
(4) Cov txheej txheem ziab ntawm tus number case
Nyob rau hauv tinplate luam ntawv ntau lawm, lub ziab ntawm number case yog ib tug complex physicochemical tshuaj tiv thaiv txheej txheem. Nws yog ib qho tsim nyog yuav tsum tswj xyuas qhov kev ziab kom ceev ntawm tus number case thiab ua tus tswv ntawm lub cev thiab tshuaj tshuab hauv kev ziab khaub ncaws, thiaj li ua tau zoo ua haujlwm sai thiab ua kom cov khoom zoo. Ink drying sai heev yuav txo qhov kev sib kis ntawm tus number case thiab cuam tshuam rau kev ua tiav ntawm kev tsim khoom; Ua rau lub imprint yuav faint, tus number case xim yog lub teeb, thiab tus number case qhuav knot tshwm nyob rau saum npoo ntawm cov ntawv luam ntawv thiab number case roller, uas cuam tshuam tus number case qis hauv kev sib kis; Nthuav cov duab thiab cov ntawv qhuav knot txheej ntawm cov ntawv luam tawm sab nraud; Tus nqi ntawm cov desiccant loj dhau, ua rau muaj kev nce ntxiv ntawm tus number case adsorption, qias neeg seem thiab lwm yam tshwm sim. Lub tshuab ziab khaub ncaws qeeb dhau, uas tuaj yeem ua rau overprinting nyuaj, adhesion, adhesion, thiab lwm yam., thiab txo firmness; Nws yog ib qho yooj yim ua rau khawb thaum kis tau tus mob. Yog li ntawd, qhov ziab ceev ntawm tus number case yuav tsum tsim nyog, nrawm dhau thiab qeeb dhau yog qhov tsis zoo.
(5) Cov qauv tshwj xeeb ntawm cov khoom siv luam ntawv
Vim muaj cov substrates sib txawv, lub auxiliary mechanism ntawm lub tshuab luam ntawv tinplate kuj txawv ntawm cov ntawv luam ntawv offset tshuab luam ntawv. Tinplate yog insoluble nyob rau hauv dej thiab tsis adsorb cov kuab tshuaj, yog li luam ntawv inks yuav tsum tau ci nyob rau hauv high kub kom cov kuab tshuaj volatilize thiab solidify lub conjunctiva. Yog li ntawd, cov txheej txheem luam ntawv feem ntau yuav tsum tau nruab nrog lub tshuab ziab khaub ncaws. Tag nrho cov tinplate luam ntawv tsis siv neeg kab yog feem ntau txog 50 meters ntev, nrog rau cov yam ntxwv ntawm precision thiab loj. Tsis tas li ntawd, lub tshuab luam ntawv tinplate yog tswj los ntawm kev siv cov ntawv hlau nplaum thiab ob daim ntawv, thiab lub siab tawv ntawm cov khoom siv tinplate kuj txiav txim siab tias cov txheej txheem txuas ntxiv ntawm cov hlau tsis tuaj yeem siv rau hauv cov txheej txheem luam ntawv, thiab cov qauv ntawm kev sib tw, kev sib tw. thiab stacking qhov chaw txawv ntawm lub tshuab luam ntawv offset ntawm cov ntawv luam ntawv.
