Nrog rau kev txhim kho ntawm thev naus laus zis thiab thev naus laus zis, cov roj-based inks tau maj mam raug tshem tawm, thiab ntau yam inks tshiab tau txuas ntxiv tsim. Txawm li cas los xij, resin-based inks (xa mus rau inks ua los ntawm resin ua tus loj phau ntawv) tseem yog cov feem ntau siv inks hauv offset luam ntawv. Ntau yam. Hauv kev siv cov kua mem, feem ntau yuav tsum kho cov luam ntawv haum ntawm tus number case raws li cov yam ntxwv ntawm luam ntawv, thaj chaw ua haujlwm thiab cov txheej txheem ntau lawm, yog li nws tsim nyog rau lub tshuab luam ntawv kom nkag siab txog kev ua haujlwm ntawm tus number case adjuvant. Cov. Hauv cov hauv qab no, tus neeg sau qhia luv luv txog cov haujlwm thiab cov txheej txheem ntawm ntau tus number case adjuvants feem ntau siv hauv kev ua haujlwm thiab qee qhov teeb meem uas yuav tsum tau them sai sai rau thaum siv, rau kev siv los ntawm cov phooj ywg.
Ua ntej, cov viscosity thiab fluidity modifiers muaj ntau hom, lub luag haujlwm yog kho cov fluidity thiab viscosity ntawm tus number case, feem ntau suav nrog cov kua roj vanish thiab debonding tus neeg sawv cev. Cov kua roj vanish feem ntau yog xya ntau yam ntawm cov roj No. 0 (piv txwv li, roj sab nraum tus lej) rau No. 6 roj. Lub viscosity yog qhov loj tshaj plaws nrog xoom roj, thiab cov roj tau txo qis hauv qhov ntau, tab sis qee qhov tsis siv. Ntawm chav kawm, muaj lwm yam ntau yam ntawm cov kua roj vanish.
Cov lus qhia tseem ceeb muaj raws li hauv qab no:
1. Tus lej 6 roj Nws yog ib qho ntawm cov tsoos ib txwm siv cov number case adjuvants. Nws yog tsuas yog siv los ua kom muaj qhov fluidity ntawm tus number case, thiab tib lub sijhawm nws tuaj yeem txo qhov viscosity ntawm tus number case. Qhov ntau npaum li cas ntawm cov hom resin feem ntau tsawg dua 5%. Qhov ntxiv yuav txo qhov dryness thiab ci ntawm tus number case. 2. No. 0 cov kua roj vanish (tseem hu ua cov roj sab nraud) Cov roj hauv cov roj pleev cov roj, yuav luag tsis muaj kev tsis haum, yog cov kua pob tshab ywj pheej nrog cov viscosity siab dua. Nws yog tsuas yog siv los ua kom qhov viscosity ntawm tus number case, txo qhov degree ntawm emulsification, kho lub viscosity ntawm tus number case ua ntej thiab tom qab cov xim, kom qhov viscosity ntawm tus thawj luam tawm number case loj me ntsis, thiab hloov pauv ntawm tus number case yog khees me ntsis lawm. Qhov ntau npaum li cas feem ntau hauv qab 5%, yog li kom tsis txhob cuam tshuam rau cov khoom ziab ziab. 3. Cov kua roj vanish yog cov viscous ntau dua li roj 6 thiab siv los kho cov npliag ntawm tus number case, tab sis nws tsis cuam tshuam rau qhov viscosity ntawm tus number case. Qhov ntau npaum li cas feem ntau nyob ib ncig ntawm 3%. Qhov sib ntxiv ntawm cov kua roj vanish tsis cuam tshuam rau qhov ci thiab nplaum nrawm nrawm ntawm tus number case, thiab muaj cov nyhuv me me ntawm cov dryness. 4. Diluent Viscosity yog me dua li ntawm roj naj npawb 6, tuaj yeem nce cov npliag ntawm tus number case thiab txo qhov viscosity, thiab muaj cov yam ntxwv ntawm kev haus tsawg dua tab sis cov nyhuv pom tseeb. Qhov ntau npaum li cas feem ntau hauv qab 3%, thiab cov gloss thiab dryness ntawm tus number case tsis tshuam cuam tshuam tom qab ntxiv. 5. siab cov roj kerosene (av kerosene aviation) muaj qhov kub npau npau ntawm 250-290 ° C. Nws yog cov kua roj zoo nyob. Nws muaj qhov ua tsis zoo nrog tus number case thiab tuaj yeem siv ncaj qha inks los txo cov viscosity ntawm tus number case thiab nce qhov ntws mus rau qee yam. Kev sib deev, tseem muaj cov yam ntxwv ntawm tsawg dua cov nyhuv thiab tsawg dua. Qhov ntau npaum li cas feem ntau los ntawm 1% mus rau 2% kom tau raws li qhov xav tau, thiab tau kawg, nws tuaj yeem nce lossis txo qis dua raws li qhov tsim nyog. Nws tsis cuam tshuam rau cov duab ci thiab nplaum ntawm tus number case tom qab ntxiv, thiab muaj cov nyhuv me me ntawm cov cuab yeej ziab khaub ncaws. 6. Lub tshuab rho tawm (tseem hu ua detackifier) yog qhov muab tshuaj txhuam thiab yog ib qho ntawm ib txwm nyob ntawm cov number case. Nws muaj qhov ua tau zoo ntawm kev txo qhov viscosity ntawm tus number case tab sis tsis muaj qhov ua kom ntau ntxiv, thiab tuaj yeem siv ua ke nrog cov kua roj vanish, roj thib rau, lossis cov zoo li, lossis tuaj yeem siv ib leeg. Tus nqi feem ntau tsawg dua 5%, thiab ntau dhau heev yuav ua rau daim phiaj qias neeg thiab txo qhov ci, kom qhuav thiab nplaum ntawm tus number case. Cov ntawv luam ntawv uas yuav tsum muaj txheej txheej zaj duab xis yuav tsum muaj kev tswj hwm tsis zoo, txwv tsis pub nws yuav ua rau muaj qhov tsis xws xws li hlwv thiab tsis nplaum. 7. number case tsis raug (tseem hu ua number case additive) yog hom tshiab ntawm number case adjuvant. Nws muaj miscibility zoo heev nrog tus number case thiab yuav tsis dilute tus number case thaum ntxiv tus number case. Nws tuaj yeem txo qhov viscosity ntawm tus number case thiab nce cov fluidity. Qhov ntau npaum li cas ntawm 3% txog 8%, thiab tuaj yeem nce lossis txo qis raws li qhov tsim nyog. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav tsis cuam tshuam rau qhov ziab qhuav, tab sis ntau dhau yuav txo qhov ci thiab nplaum ntawm tus number case.
Thib ob, lub tshuab ziab khaub ncaws yog siv rau kev kho kom haum ntawm kev ziab qhuav. Nws muaj ob hom tseem ceeb: 1. Cov roj dawb dawb yog cov roj ntsha sib xyaw ua ke uas txhawb nqa kom ua kom ziab ib yam ntawm cov txheej sab hauv thiab sab nrauv. Nws tuaj yeem siv ib leeg los yog ua ke nrog roj liab liab. Nws muaj cov qauv ua kom muaj zog ziab thiab tuaj yeem txhim kho qhov ci ntawm luam ntawv rau qee yam. Qhov ntau npaum li qhov zoo dua 5% lossis tsawg dua, thiab qhov siab tshaj yog tsis ntau tshaj 10%. Ntau dhau lawm yuav ua rau muaj kev phom sij zoo xws li cov roj av qhuav, qias neeg thiab cov roj hmab qhuav, thiab lwm yam Yog tias muaj qhov tsis ua tiav, cov roj dawb qhuav (tsawg dua 3%) yuav raug txo kom tsawg raws li qhov tsim nyog, thiab me me ntawm liab roj (li ntawm 0.5%) ntxiv. daws. Nws yuav tsum raug sau tseg tias cov roj dawb qhuav muaj cov hlau hnyav hnyav uas ua rau muaj kev puas tsuaj rau tib neeg lub cev, yog li nws tsis tuaj yeem siv rau kev luam tawm cov zaub mov ntim thiab lwm yam kev xav tau huv. Yog tias qhov ntawv luam tawm tuaj yeem hloov mus rau cov roj qhuav liab lossis sib xyaw desiccant. 2. Cov roj ntsha liab liab muaj cov yam ntxwv ntawm kev haus tshuaj tsawg dua thiab pom tseeb ntawm cov nyhuv, tuaj yeem ua kom qhuav lub ntsej muag nyob rau sab nrauv ntawm tus number case, thiab tuaj yeem txhim kho qhov ci ntawm cov ntawv luam tawm.
Feem ntau siv nyob rau hauv kev sib xyaw nrog roj dawb qhuav, qee zaum nws tuaj yeem siv ib leeg. Qhov ntau npaum no feem ntau li ntawm 1%, thiab qhov dhau mus yog qhov yooj yim los tsim qhov tshwm sim ntawm "roj hmab qhuav roj". Cov ntaub ntawv ntawm "overprinting qhuav" (piv txwv li ntub-qhuav luam ntawv), thawj ob xim tsis tuaj yeem siv lossis siv tsawg li tsawg tau kom tsis txhob muaj kab npoo crystallization ntawm tus number case txheej. Tsis tas li ntawd, txawm hais tias cov roj liab liab liab tsaus xim lossis ntshav, nws feem ntau yog pob tshab thiab tsis cuam tshuam rau cov xim xim ntawm tus number case. Txawm tias lub teeb inks xws li daj thiab dawb feem ntau siv. 3. Mixic Desiccant Ntxiv nrog rau ob qho kev npau suav ntawm no, lwm qhov tshiab tshaj tawm tshuab ziab khaub ncaws yog ib yam khoom tsis ntev los no tsim los ntawm cov tsim kua lag luam thiab yog kev sib xyaw. Nws muaj cov yam ntxwv ntawm kev txhawb tus number case kom ua tiav thiab kom qhuav ntawm sab hauv thiab sab hauv lub rooj, thiab tuaj yeem txhim kho qhov ci ntawm kev luam ntawv thiab kev ceev nrawm ntawm tus number case rau qee yam. Vim tias nws tsis muaj cov hlau hnyav uas ua teeb meem rau tib neeg lub cev, nws tuaj yeem siv los ua lwm txoj hauv kev siv roj dawb rau kev luam tawm cov khoom lag luam xws li ntim zaub mov. Nws tuaj yeem siv ib leeg los yog ua ke nrog roj dawb dawb yog tias nws tsis huv. Thaum siv ib leeg, qhov ntau npaum feem ntau tswj tau qis dua 2%. Tsis tas li ntawd, kev sib xyaw ua ke nws tus kheej yog tsaus liab lossis purplish liab, tab sis txij li nws tau pob tshab thiab siv ntau me me, feem ntau nws tsis cuam tshuam rau cov xim xim ntawm tus number case zoo li nrog cov roj liab liab.
3. Tus neeg sawv cev zom zaws (cov kua nyeem ua kom paub meej) Tus neeg sawv cev siv los tsim cov xim sib xyaw xim, feem ntau suav nrog tus number case dawb thiab tshem tawm. 1. Tus number case dawb yog ib hom ntawm tus neeg sawv cev nquag siv hauv kev sib xyaw xim teeb cov xim. Lub teeb xim-cov xim sib xyaw ua ke nrog nws muaj qhov zais zais zoo, thiab tus number case yog dawb thiab tuab thiab muaj cov hmoov zoo nkauj, uas muaj qhov cuam tshuam ntawm lwm cov nyias. Txawm li cas los xij, vim tias cov xim number case dawb xim piv txwv yog loj thiab cov lus tau ntxhib, cov luam ntawv tsis zoo tagnrho, thiab qee zaum tus number case hloov thiab hloov tsis ua haujlwm yog cuam tshuam rau qhov tsis ua hauj lwm, thiab kev nplaum ntawm tus number case kuj tsawg. Cov luam ntawv uas yuav tsum tau ua yeeb yaj kiab qee zaum muaj qhov tsis zoo ntawm tsis ua raws li zoo. Txhawm rau zam qhov tsis ua tiav, siv lub teeb pleev lossis cov kua roj vanish. Rau cov ntawv luam uas yuav tsum tau siv tus cwj mem dawb los ua daim nyias nyias, nws raug nquahu kom xaiv cov cwj mem dawb zoo dua, lossis siv cov mem pleev xim dawb thiab ci teeb ci muab tshuaj, thiaj li ua kom tswj tau qhov tsis zoo ntawm cov number case dawb, thiab txhim kho kev luam ntawv haum Tus number case thiab txhim kho tus number case. Lub ci thiab nplaum ntawm qhov luam ntawv. 2. Tus neeg sawv cev lightening (tseem hu ua tus neeg saib xyuas lub teeb ci) yog tus neeg sawv cev tiv thaiv kom tsis txhob muaj qhov pom kev tsis zoo nrog tus number case. Nws tsuas yog siv los ntxiv xim rau tus number case tsis cuam tshuam rau lub suab xim ntawm tus number case thawj. Qhov qis dua ntawm qhov tsis zoo ntawd muaj qhov tsis zoo me ntsis ziab thiab ci, thiab cov desiccant yuav tsum tau ntxiv yog xav tau. Cov qib siab ntawm fumigant muaj cov yam ntxwv ntawm lub siab gloss, zoo luam tawm thiab ua kom qhuav nruab nrab, feem ntau tsis siv desiccant. Nws feem ntau yog siv ib leeg los yog ua ke nrog cov dawb mem kua. 3. Brightening muab tshuaj txhuam yog zoo tshaj plaws number case thinner. Ntxiv rau tib qhov zoo xws li tus neeg sawv cev pom kev, nws kuj muaj ntau dua pob tshab thiab ci, zoo dua printability thiab dryness. Ntxiv rau qhov tau siv los ua cov ntawv nyias nyias, qee zaum nws tuaj yeem siv los ua cov iav me ntsis ntawm cov ntawv luam ntawv, uas muaj cov nplaim zoo tab sis tsis siab hauv kev txhim kho abrasion.
4. Ua tiav varnish yog ib hom ntawm cov kua roj vanish luam tawm uas tuaj yeem thov ncaj qha rau saum npoo ntawm luam ntawv siv cov ntawv luam ntawv luam ntawv. Nws muaj cov xim zoo heev, ci thiab puas ua hauj, dej tsis kam thiab hnyav kuj. Nws yog tsuas yog siv rau glazing nyob rau saum npoo ntawm cov ntawv luam tawm, thiab qee zaum nws kuj tseem tuaj yeem siv los ua cov tawv tawv nyias. Tus number case diluted muaj siab gloss thiab puas ua hauj thiab zoo printability. Txawm li cas los xij, cov kua roj vanish yuav txo qhov kev pab cuam lub neej ntawm tus number case roller thiab daim pam, yog li nws yuav tsum zam kom tsis txhob ua ntau dua li qhov ua tau, thiab nws yog qhov zoo dua los siv lub ntsej muag txhuam. Offset varnishes tau faib ua hom ci thiab matt, thiab yuav tsum tau txawv thaum siv.
Qhov saum toj no tsuas yog ib feem ntawm tus cwj mem kua txuas, thiab tseem muaj cov neeg ziab kom qhuav, tiv thaiv cov nplaum, cov tshuaj txhuam tawm tsam, thiab lwm yam, uas yuav tsis rov ua dua ntawm no.
