Nrog txoj kev loj hlob thiab kev vam meej ntawm tib neeg, kev lag luam luam kuj tau tsim los ntawm leaps thiab ciam teb. Lub advent ntawm cov teb ua chaw luam yeeb tau tso cov khoom tshiab ntawm cov cua kub ntawm cov ntawv luam tawm. Vim tias zoo tib yam ntawv tsis tuaj yeem ua tau raws li cov kev cai luam ntawm txoj kev luam tawm tshiab, foaming yog ib qho teeb meem loj thiab muaj teeb meem hauv cov ntawv luam tawm.
Ua ntej, txoj ntsiab cai ntawm kev foaming
Cov ntawv luam ntawm cov luam ntawv muaj cov yam ntxwv ntawm high-speed printing, feem ntau 4 txog 50,000 nplooj ntawv ib teev twg (thiab nruab nrab lithographic luam ntawv tsuas yog 10,000 nplooj ntawv ib teev), thiab ncaj ncaj folding tom qab luam ntawv thiab ziab, xws li ceev ceev Yuav kom tiv thaiv cov luam tawm tsis txav xws li ink ink dryness thiab rov tom qab, cov ntawv luam tawm yuav tsum tau ceev nrooj qhuav, thiab txoj kev zoo tshaj plaws kom sai ziab khaub ncaws yog kub cua sov, yog li ntawd muaj qhov cub hauv cov qauv ntawm lub cav tshuab, Cov luam daim ntawv kub kom tso tus cwj mem kom qhuav sai sai.
Cov dej muaj yees, thiab dej tawm rau sab nraud thaum dej qhuav ntawm qhov kub (qhov kub ntawm qhov ziab feem ntau yog 140 ° C). Txawm li cas los xij, yog tias lub luam ntawv tseem nyob rau tib qho chaw ntawm ob sab ntawm daim ntawv, thiab tus lej ntawm tus cwj mem loj loj, cov pa dej tsis tuaj yeem tawm sab nraud vim tus xaum kauv daim npog tag, uas yog ua kom foaming.
Qhov ob, ob peb yam tseem ceeb uas cuam tshuam rau qhov sib txawv ntawm lub tshuab raj:
Raws li txoj cai saum toj no, peb tuaj yeem ua raws li peb yam uas cuam tshuam txog luam ntawv thiab kev luam ntawv luam yeeb ntau: kev luam ntawv, xim number case, ntawv, thiab ntau yam tseem ceeb hauv kev luam tawm yog raws li nram no:
1. Printing tshuab kom sov thiab kub ceev
Vim hais tias qhov kev ceev ntawm cov ntawv luam ntawv yog ceev, qhov chaw nyob ntawm daim ntawv hauv qhov cub tseem luv. Los xyuas kom meej txog qhov qub ziab ntawm tus cwj pwm thiab tiv thaiv cov cim ntawm cov ntawv tom qab, nws tsim nyog yuav ua rau kom ziab thiab zij ziab ntawm tus cwj pwm, tab sis raws li cov roj. Kev loj hlob lub tswv yim, thaum lub siab yog qhov ruaj khov (P1 = P2), qhov siab dua qhov ntsuas kub (T2> T2), qhov loj qhov ntim (V2> V1), thaum lub sij hawm luam ntawv, qhov kub kom qhuav dhau, thiab foaming tshwm sim. Qhov teeb meem, tab sis yog tias qhov kub kom qhuav tsis tshua muaj, yuav muaj teeb meem xws li rov qab luam tawm vim tsis muaj tus cwj mem tsis ziab.
2. qhov kev zuaj ntawm cov ziab khaub ncaws
Tus number case uas siv rau kev luam ntawv yog ib qho cim tshwj xeeb. Yog li ntawd, raws li cov fluidity thiab dryness ntawm tus cwj pwm, cov nyhuv foam ntawm cov lus teb yog zoo heev cuam tshuam, tus number case yog yooj yim dua qhuav, qhov qis qhov ziab tshav kub ntawm lub cav tshuab, tsawg dua yuav ua npuas, tab sis tus number case uas dries dhau sai sai, tom qab luam ntawv Gloss feem ntau kuj tsawg.
Thib peb, cov xwm txheej luam tawm hauv kev sib hloov luam ntawv. Cov ntawv yuav tsum muaj ntawv thiab cuav yuav muaj ntau dua thiab siab dua, thiab nws txoj kev loj hlob zoo: nrog kev txhim kho cov kev ua haujlwm ntawm kev luam ntawv. Cov zauv luam ntawv ntawm lub tshuab cav yuav tsum ceev thiab sai dua, thiab qhov ziab tshav kub yuav siab dua thiab siab zog. Vim li no, yuav tsum muaj cov lej thiab daim ntawv yuav muaj ntau dua thiab ntau dua. Ntawm qhov one hand, luam ntawv number case yog yuav tsum ua kom lub pob luj tom qab luam ntawv. Hauv qab no, nws tuaj yeem qhuav qhuav sai dua, thiab ntawm qhov tod tes, daim ntawv luam ntawv yuav tsum tau ua kom nws tsis tu ncua nws qhov kev kub ntxhov. Los ntawm kev kho lub cohesion, huab cua permeability thiab txheej formulation ntawm daim ntawv, lub cohesion thiab kua absorbed ntawm daim ntawv tuaj yeem kho kom zoo dua lub hom phiaj ntawm qhov kub siab ua haujlwm ntawm daim ntawv.
