Vim muaj qhov sib txawv loj hauv kev luam ntawv ib puag ncig kub thiab av noo, cov txheej txheem ntawm cov khoom sib txawv thiab kev luam tawm, txhua hom xim xim xim, txuas siv los ntawm kev faib ua feem ntawm cov khoom thiab cov khoom ntim yuav luag tas li, yog tias tseem tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. ntau yam xwm txheej ntawm kev tsim nyog luam ntawv, luam ntawv number case additives tuaj yeem muab ntxiv los kho tus number case kom nws ua tau raws li kev tsim nyog luam ntawv.Daim ntawv no luv luv qhia txog lub luag haujlwm ntawm cov kua nplaum uas siv tau thiab lawv txoj kev siv, cov ntsiab lus rau cov phooj ywg siv:
Ink additives
Ink auxiliaries yog cov ntaub ntawv pabcuam siv los kho tus cwj mem kom hloov mus rau ntau yam kev luam ntawv.Muaj ntau ntau hom ink additives, feem ntau siv cov nplaum, nplawm lub teeb tus neeg saib xyuas, desiccant, qeeb ziab tus neeg saib xyuas, diluent, txhuam resistant tus neeg saib xyuas, npog gloss roj, ntxiv rau cov saum toj no ob peb feem ntau siv number case additives, muaj anti fouling agent, anti -foam tus neeg saib xyuas, luam ntawv roj, thiab lwm yam Los ntawm qhov pom ntawm kev txhim kho kev luam ntawv thiab kev ua haujlwm zoo, raws li kev hloov pauv ntawm cov ntawv luam ntawv, nws yog qhov zoo rau kev ntxiv qee cov additives kom tsim nyog rau hauv cov ntawv xaiv los xyuas kom cov luam ntawv ib txwm muaj.
01 Tshem Tawm Cov nplaum
Adhesives muaj ib tug me me viscosity thiab feem ntau siv nyob rau hauv lithography thiab nyem printing inks kom txo lawv viscosity.Nyob rau hauv offset printing, vim cov kev hloov nyob rau hauv daim ntawv lub zog thiab luam ntawv tej yam kev mob, xws li roj nqus, tsis zoo deg zog, zoo thiab tsis zoo txheej poob tshwm sim, thaum lub desiccant ntau dhau los yog chav tsev kub ntawm lub rhiav luam ntawv yog tsawg heev, nws yuav ua rau cov ntawv plaub hau, luam ntawv pawg phaj, pasting phaj thiab lwm yam tsis zoo, cuam tshuam rau kev luam ntawv zoo.Yog li ntawd, thaum muaj qhov tshwm sim saum toj no tshwm sim, qhov tsim nyog tus nqi ntawm cov nplaum tshem tawm tuaj yeem raug ntxiv kom tsis muaj zog thiab tshem tawm lub luag haujlwm ntawm cov kev ua txhaum saum toj no.
02 Los ntawm Lub Teeb Tus Neeg Saib Xyuas
Tshem tawm diluent, tseem hu ua diluent, yog ib qho loj ntawm offset printing additives.Muaj ob hom diluent: ib qho yog cov roj pob tshab, siv rau cov xim ci ci;Ib tug yog ib tug resin - hom diluent, siv rau resin number case.Yog tias cov xim luam ntawv pom pom tias tob dhau los ua kom rov qab tau cov ntawv sau qub, koj tuaj yeem ntxiv qhov tsim nyog ntawm tus neeg saib xyuas lub teeb, kom nws ua tiav cov txiaj ntsig zoo.
03 Desiccant
Desiccant yog ib qho tseem ceeb tshaj plaws ntawm kev luam ntawv number case auxiliaries.Raws li qhov sib txawv ntawm cov ntawv luam tawm thiab cov ntawv luam tawm, cov khoom siv desiccant, hom thiab kev siv kuj txawv.Feem ntau siv desiccant yog cov roj qhuav qhuav, cov roj qhuav qhuav ob yam, cov roj qhuav qhuav qhuav los ntawm sab nraud mus rau sab hauv, cov roj dawb qhuav yog nrog rau sab nraud tib lub sijhawm qhuav.Thaum luam ntawv, kuv xaiv hom roj kom qhuav raws li qhov yuav tsum tau luam ntawv thiab xim number case.General dryness roj ntau npaum li cas yog 2% -3%, ntau dhau yuav rov qab, yog li ntawd qhov ziab kom qhuav.
04 Slow Drying Agent
Desiccant kuj hu ua antioxidants, qhov no yog ib tug desiccant thiab cov opposite number case additives.Nyob rau hauv cov txheej txheem luam ntawv, vim muaj ntau yam laj thawj feem ntau ua rau downtime, thaum lub sij hawm downtime ntev, tus number case yuav qhuav ntawm daim tawv nqaij.Yuav kom daws tau qhov teeb meem no, nws yog ib qho tsim nyog yuav tsum tau ntxiv qhov tsim nyog ntawm desiccant rau tus number case ntawm lub tshuab, thiab khiav lub tshuab ob peb zaug, kom tsis txhob qhuav sai heev.
05 Nyias,
Hauv kev luam ntawv, vim yog tus number case viscosity ntau dhau los yog cov ntawv tsis zoo, qhov tsis zoo xws li cov ntaub plaub rub tawm thiab phaj poob feem ntau tshwm sim, uas cuam tshuam rau kev luam ntawv ib txwm.Nyob rau lub sijhawm no, ntxiv rau ntxiv qhov tsim nyog ntawm cov nplaum kom txo cov viscidity ntawm tus number case, ib qho me me ntawm cov diluent tuaj yeem ntxiv los txo cov viscidity ntawm tus number case, kom luam ntawv tuaj yeem ua haujlwm zoo.Muaj ntau ntau hom diluent, feem ntau tsis tshua muaj viscosity rau number case roj.
06 Kev Tiv Thaiv Kev Sib Tw
Friction resistant agent kuj hu ua smoothing agent.Feem ntau ntawm cov tshuaj no yog ua los ntawm cov ntaub ntawv siv quav ciab.Thaum cov luam ntawv number case yog ntxhib, xws li number case dawb, kub thiab nyiaj number case, ntxiv tus nqi ntawm kev sib txhuam resistant tus neeg saib xyuas kom muaj kev sib txhuam thiab smoothness ntawm cov ntaub ntawv luam ntawv.
07 Cap Lub Teeb Roj
Cov cim lag luam, cov duab albums thiab lwm yam khoom lag luam qib siab, luam ntawv nto feem ntau los ntawm kev kho kom zoo nkauj, thiaj li ua tiav lub teeb pom kev zoo, siv cov roj gloss, tuaj yeem muab sib xyaw rau hauv cov ntawv luam ntawv ua ntej luam ntawv, tuaj yeem luam tawm tom qab luam ntawv. ib gloss.Tab sis tom qab lub gloss ua luam ntawv, tom qab ib tug ntev lub sij hawm yuav yellowing, lub teeb kuj tsis zoo, yog li tam sim no muaj ntau lwm txoj kev rau gloss roj ntawm lub teeb tshiab roj yog siv.
