Luam tawm lithographic yog raws li cov qauv uas roj thiab dej yog insoluble. Daim duab ib feem ntawm lub tshuab luam ntawv tuaj yeem yog hydrophibic thiab hydrophobic, thiab cov seem tuaj yeem muaj cov adsorption thiab hydrophobic roj ua ntej. Ib qho ntxiv, offset luam ntawv yog tus cwj pwm los ntawm kev siv cov tshuab luam ntawv tsis ncaj, kev siv ntawm dot xim txoj kev rau kev ua me nyuam xim rau kev ua tub yug me nyuam. Nws yog ib qho tseem ceeb heev rau tswv cov number case kom raug rau hauv offset luam ntawv, qhov tob ntawm cov xim kua ntxwv, qhov tseeb ntawm cov xim qhuav thiab ua cov luam tawm. Yog li ntawd, txawm hais tias qhov sib npaug ntawm cov number case thiab kev ntxuav tuaj yeem tswj tau thiab tswj tau yog tus yuam sij los xyuas kom meej cov khoom lag luam zoo. Raws li cov tshuab luam ntawv uas txawj tshaj plaws, peb yuav tsum tsis tsuas nkag siab qhov kev sib raug zoo ntawm number case thiab ntxuav li cas, tab sis kuj tseem ceeb ntawm number case thiab ntxuav li cas.
1. Cov kev sib raug zoo ntawm number case thiab ntxuav
Ink tshuav nyiaj txhais tau tias nyob rau hauv qee yam kev luam tawm luam ntawv yog muab kev sib tw ntawm cov roj emulsified tau raug kev sib tw nrog cov number case emulsified tau raug kev sib tw nrog cov number case ntawm lub xub nrog cov kua mis uas muaj tsawg tshaj plaws.
Qhov tseem ceeb tshaj plaws nyob rau hauv number case tshuav yog tswj ntawm cov dej noo thiab kua mem. Cov dej noo yog tsim cov dej thiab surfactants. Cov tshuaj ntub dej tuaj yeem ua kom tiav cov txheej txheem, thiab muaj lub peev xwm ntxuav thiab ruaj khov PH nqi los xyuas kom meej tias cov qauv tsis huv.
1) Lub luag haujlwm ntawm cov dej noo
Ib zaj yeeb yaj kiab dej tsis muaj dej yog tsim nyob rau hauv qhov dawb paug ntawm lub tshuab luam ntawv kom tiv thaiv tus mem daim duab thiab cov ntawv los ntawm infiltrating rau kev tiv thaiv cov phiaj av.
Ef electrolyte hauv cov tshuaj electrolyte yog siv los siv cov kab mob thiab kua muag, tas li kev tsim lub hydrophilicity los tswj lub hydrophilicity los tswj cov dej qab zib tshiab ntawm nplooj ntawv.
③ Tswj qhov kub ntawm nplooj ntawv tso kua mis. Raws li qhov ceev ntawm lub tshuab luam ntawv tshiab tau txais sai dua thiab nrawm dua rau qhov ntsuas kub ntawm tus number case ntawm tus number case yuav nce ntxiv, ua rau muaj kev nce ntxiv. Yog li ntawd, lub tshuab ceev ceev tso rau cov kua tshiab rau cov kua dej noo, uas yog, cov number case ntawm tus kua mem kua txiv hmab txiv ntoo thaum nws hu rau hauv number caser los ntawm kev teeb tsa.
Tsis txhob loj lossis thim cov ntawv nyeem. Cov kev daws teeb meem noo yuav tsum muaj lub luag haujlwm ntawm kev ruaj khov txoj cai ntawm cov duab kos kom ntseeg tau tias tsis muaj peev xwm ua rau tag nrho cov txheej txheem luam ntawv.
Tus number case feem ntau muaj cov xim pigments, fillers, binders thiab aiteriary ntxiv thiab kho qhov muag ntawm tus number case yuav tsum tau txiav txim siab thaum xaiv cov number case.
Cov cuab yeej rheological ntawm tus number case yog lub hauv paus tseem ceeb rau kev txiav txim siab seb puas muaj tus mem kua tau ua haujlwm zoo. Cov khoom siv hluav taws xob ntawm cov number case feem ntau yog nyob ntawm cov number cask binder, ntawm chav kawm, tseem tuaj yeem hloov kho kom raug los ntawm ib pab pawg ntxiv. Qhov kev ntsuas ntawm Ink Rheholog tuaj yeem xav los ntawm cov ntsiab lus tseem ceeb ntawm Ink rheology, uas yog, inkostropy, yieldropy thiab fircise. Hauv kev tsim khoom tiag tiag, tsuas yog los ntawm kev siv cov ntsuas kev ua tau zoo tuaj yeem peb paub txog cov khoom luam tawm ntawm ntau hom inks, thiaj li ua tiav lub hom phiaj ntawm kev xaiv cov inks uas tau raws li cov kev luam tawm.
Number case thiab dej yuav tsum muaj nyob rau tib lub sijhawm ntawm kev luam ntawv kom muaj kev sib npaug, yog tias khaws cov kua mem, thiab ua kom lub chaw luam ntawv muaj tseeb, thiab kom lub chaw luam ntawv muaj zog, thiab kom lub chaw luam ntawv muaj tseeb, thiab ua kom lub chaw luam ntawv muaj zog, thiab kom lub chaw luam ntawv tau zoo huv si, thiab kom cov number case, thiab kom lub chaw luam ntawv muaj zog, thiab kom lub chaw luam ntawv muaj zog, thiab kom lub chaw luam ntawv tau zoo nkauj thiab huv si
Hauv kev luam ntawv, qhov tob ntawm ink imprinting tsis tsuas yog cuam tshuam nrog tus nqi ntawm tus mem kua hopper, tab sis kuj tseem cuam tshuam nrog kev cuam tshuam nrog tus cwj pwm ntawm nplooj ntawv. Thaum cov dej noo ntawm cov txheej nce, xim mem kua ntawm qhov ua tau zoo me me txo qis thiab ua ntais. Ntawm qhov tsis sib xws, cov dej tsis zoo txo cov ntsiab lus dej ntawm lub phaj, thiab number cases ntawm cov luam tawm yuav muaj ntxig dua li tus thawj. Yog li ntawd, nce lossis txo tus nqi ntawm cov kua mem rau thiab cov dej uas muab rau lub phaj yuav hloov qhov tob ntawm cov kua mem kua mem. Hauv cov txheej txheem luam ntawv, nws yuav tsum tau hloov kho raws li qhov xwm txheej tiag tiag. Yuav tsum tsis txhob cia siab rau kev txo cov dej haus dej txhawm rau txhim kho cov kua mem kua, vim tias cov dej tswj tau me me, poob cov kua mem, yooj yim kom ua rau qhov khoob khoob khoob.
Muaj, txawm li cas los xij, ib qho xav tau kev tiv thaiv tawm tsam kev tshaj tawm. Thaum cov dej yog ntau dhau thiab cov kua member yog sib dua, koj yuav tsum tsis txhob quav ntsej tias muaj cov kua dej tiag tiag, tsis yog txo cov kua mem. Xws li riprocating nce nyob rau hauv tus nqi ntawm number case ntawm number case thiab thaum kawg txhua tus shorts ntawm cov dej thiab number case tau nthuav tawm, kom cov luam ntawv tsis tuaj yeem ua haujlwm ib txwm.
Cov ntawv luam tawm kev paub, hauv kev tsim cov khoom siv tsawg tshaj plaws, yog li cov khoom siv hluav taws xob tsis sib xws Tus neeg tawm tswv yim kev siv cov dej me, tuab tus cwj mem ntawm no yog hais txog qhov tsawg kawg nkaus ntawm cov dej uas yog qhov tsis huv ntawm nplooj ntawv tsis yog qias neeg; Lub npe-hu ua tuab mem kua mem kuj tseem raws cov dej me me, loj ua rau muaj emulsification ntau dhau ntawm cov kua mem, thiab cov number case txheej tsis yooj yim sua kom tuab.
