Tsis ntev los no, ntau qhov sib txawv ntawm cov nthwv dej txias tau tsoo ntau zaus los ntawm sab qaum teb mus rau sab qab teb.Ntau qhov chaw ntawm lub ntiaj teb tau ntsib kev txias txias bungee, thiab qee qhov chaw tau txais lawv thawj zaug ntawm cov daus.Nyob rau hauv cov huab cua kub tsis tshua muaj no, ntxiv rau txhua tus neeg taug kev txhua hnub, kev tsim cov ntim khoom thiab cov tuam txhab luam ntawv kuj tau cuam tshuam rau qee yam.
Yog li, ntsib cov huab cua hnyav li no, cov ntsiab lus yuav tsum tau ua dab tsintimcov tshuab luam ntawv them nyiaj rau?
Tiv thaiv web offset inks los ntawm thickening nyob rau hauv huab cua txias
Rau tus number case, yog tias chav tsev kub thiab cov kua kub ntawm tus number case tau hloov pauv, lub xeev ntawm tus number case flow yuav hloov, thiab xim yuav hloov raws li.Nyob rau tib lub sijhawm, huab cua kub tsawg yuav muaj kev cuam tshuam loj rau tus lej hloov pauv ntawm qhov chaw siab.Yog li ntawd, thaum luam ntawv cov khoom lag luam qib siab, qhov kub thiab av noo ntawm lub tshuab luam ntawv yuav tsum tau tswj nyob rau hauv txhua rooj plaub.Ntxiv rau,Kev siv tus cwj mem nyob rau lub caij ntuj no yuav tsum tau preheating ua ntej, thiaj li yuav txo tau qhov kub thiab txias hloov ntawm tus number case nws tus kheej.
Nco ntsoov tias tus number case yog tuab heev thiab viscosity loj, tab sis nws yog qhov zoo tshaj plaws tsis txhob siv cov thinner los yog number case los kho nws cov viscosity.Vim hais tias thaum tus neeg siv yuav tsum tau sib tov tus cwj mem, lub Hoobkas tsim cov number case raw tuaj yeem ua kom haum rau tag nrho cov khoom siv ntxiv, dhau qhov txwv, txawm tias tuaj yeem siv tau, kuj tseem ua rau kev ua haujlwm tsis zoo ntawm tus number case, cuam tshuam rau cov tshuab luam ntawv zoo.
Ua tib zoo saib xyuas kev siv cov kua roj vanish tiv thaiv UV
UV kua roj vanish kuj yog ib yam khoom uas yooj yim cuam tshuam los ntawm qhov kub thiab txias.Yog li ntawd, ntau tus neeg muag khoom tshwj xeeb hauv kev tsim ob hom qauv sib txawv, hom caij ntuj no thiab lub caij ntuj sov hom.Lub caij ntuj no mis muaj cov ntsiab lus qis dua lub caij ntuj sov mis,uas tuaj yeem ua kom qhov kev ua tau zoo ntawm cov kua roj vanish zoo dua thaum qhov kub thiab txias.
Nco ntsoov tias yog tias koj siv cov mis nyuj rau lub caij ntuj no nyob rau lub caij ntuj sov, nws yuav yooj yim ua rau cov roj yuav kho tsis tiav thiab tuaj yeem ua rau rov qab los.Ntawm qhov tsis sib xws, yog tias koj siv cov mis nyuj rau lub caij ntuj sov hauv lub caij ntuj no, nws yuav ua rau tsis zoo ntawm cov roj UV, ua rau muaj teeb meem blistering thiab txiv kab ntxwv tev.
Cov nyhuv ntawm huab cua txias ntawm daim ntawv
In luam ntawv ntau lawm, ntawv yog ib yam ntawm cov consumables uas yuav tsum tau siab rau ib puag ncig kub thiab av noo.Daim ntawv yog cov khoom ntxeem tau, thiab nws cov qauv yooj yim yog tsim los ntawm cov nroj tsuag fibers thiab accessories, muaj zog hydrophilic zog.Yog tias ib puag ncig kub thiab av noo tswj tsis tau zoo, nws yuav ua rau daim ntawv deformation thiab cuam tshuam rau kev luam ntawv.Yog li ntawd, kev tswj hwm qhov tsim nyog ib puag ncig kub thiab av noo yog qhov tseem ceeb los txhim kho cov khoom lag luam ntawv zoo thiab txhim kho kev tsim khoom.
Cov ntawv zoo tib yam rau ib puag ncig qhov kub thiab txias yuav tsis pom tseeb,Tab sis thaum qhov kub ntawm ib puag ncig qis dua 10 ℃, cov ntawv zoo tib yam yuav dhau los ua "nkim", qhov adhesion ntawm tus number case txheej hauv nws qhov chaw yuav poob qis., yooj yim ua rau deinking phenomenon.
Daim npav kub thiab nyiaj feem ntau yog ua los ntawm cov ntawv coated, daim ntawv dawb, daim ntawv dawb yog cov khoom siv hauv paus, thiab tom qab ntawd sib xyawPET zaj duab xislos yog aluminium foil thiab lwm yam khoom tsim.Daim npav kub thiab nyiaj daim ntawv hauv chav kawm ntawv qee qhov kev xav tau siab dua rau ib puag ncig qhov kub thiab txias, qhov no yog vim cov khoom siv hlau thiab yas yog qhov nkag siab zoo rau qhov kub thiab txias,Thaum qhov kub thiab txias ib puag ncig qis dua 10 ℃, yuav cuam tshuam zoo rau cov ntawv kub thiab nyiaj hauv chav kawm ntawv kom haum, thaum kub thiab nyiaj daim ntawv teev cov ntawv khaws cia ib puag ncig ntawm 0 ℃, los ntawm kev cob qhia luam ntawv, qhov chaw yuav muaj dej ntau. ,cuam tshuam rau kev luam ntawv ib txwm, tuaj yeem ua rau khib nyiab.Yog tias cov teeb meem saum toj no tau ntsib, thiab lub sijhawm xa khoom nruj, cov neeg ua haujlwm tuaj yeem ua ntej qhib lub raj UV kom cia cov ntawv ua haujlwm tas li, kom qhov ntsuas kub thiab qhov ntsuas kub sib npaug ua ntej luam ntawv.
Ntxiv rau,Tsis tshua muaj kub kom qhuav, tsis tshua muaj txheeb ze av noo, ntawv thiab huab cua noo noo pauv, daim ntawv yuav qhuav, ua warped, contraction, yuav ua rau tsis zoo overprinting.
Cov nyhuv ntawm qhov kub thiab txias ntawm cov nplaum nplaum
Adhesive yog ib qho tseem ceeb tshuaj npaj nyob rau hauv industrial ntau lawm niaj hnub no.Kev ua haujlwm ntawm cov nplaum ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom lag luam.Ib qho tseem ceeb kev ntsuas hauv kev tsim cov nplaum yog kev tswj qhov kub thiab txias.Feem ntau ntawm cov khoom siv raw ntawm cov nplaum yog cov organic polymers, uas muaj qhov siab ntawm qhov kub thiab txias, uas txhais tau hais tias lawv cov khoom siv dag zog thiab viscoelasticity cuam tshuam nrog kev hloov ntawm qhov kub thiab txias.Nws yuav tsum tau taw qhia tiasTsis tshua muaj kub yog lub ntsiab culprit ntawm cov kua nplaum cuav adhesion.
Thaum qhov kub thiab txias poob, qhov hardness ntawm cov nplaum yuav nyuaj, thiab kev ntxhov siab ntawm cov nplaum yog hloov.Nyob rau hauv qhov opposite low temperature state, lub polymer saw txav nyob rau hauv cov nplaum yog txwv, txo cov scalability ntawm cov nplaum.
