1.InRoduction

Number case yog cov khoom siv tsis tseem ceeb hauv cov txheej txheem luam ntawv. Nws cov kev ua tau zoo thiab daim ntawv thov ncaj qha cuam tshuam qhov ua tau zoo thiab cuam tshuam cov khoom luam tawm. To taub cov ntaub ntawv tseem ceeb ntawm Ink, suav nrog kev luam ntawv substrate, cov qauv luam ntawv thiab cov txuj ci kom qhuav rau cov kws tshawb fawb thiab cov kws tshawb nrhiav hauv cov teb ntsig.

 

2.Luam ntawv substrates rauUV inks

Cardboard: Nws muaj cov tuab tuab thiab muaj zog zoo thiab feem ntau siv rau cov ntim thawv luam ntawv. Daim Ntawv Luam Ntawv yuav tsum muaj cov number cas kom muaj cov nplaum zoo kom muaj kev hloov tuag tom qab txiav, quav quav thiab lwm yam kev ua haujlwm.
Daim yas
Polyethylene (PE): Cov saum npoo yog du thiab cov tshuaj ruaj khov yog qhov zoo, tab sis lub tshuab luam tawm tsis zoo, thiab yuav tsum tau ua haujlwm ua ntej, xws li kev kho corona. Inks rau PE plastics yuav tsum muaj kev yoog tau zoo thiab tshuaj lom neeg ua kom ntseeg tau tias tus number cas tsis poob lossis ploj mus thaum siv cov khoom yas.

Polypropylene (PP): Zoo ib yam li PE, nws tseem yuav tsum tau kho kom ntev. PP yas feem ntau siv rau luam ntawv yas cov yeeb yaj kiab, xws li cov khoom noj khoom haus ntim khoom noj. Tus number case ntawm PP zaj duab xis yuav tsum ua kom tiav cov qauv kev nyiam huv thiab muaj qhov zoo khawb tiv taus.

Polyvinyl chloride (PVC): Siv dav siv, tuaj yeem siv rau luam ntawv yas khoom xws li ntawv sau thiab khoom ua si. Thaum luam ntawv number case ntawm PVC, nws yog ib qhov tsim nyog los xav txog kev sib xyaw nrog PVC cov ntaub ntawv kom tsis txhob muaj teeb meem xws li attk los ntshav.

Lub khob
Cov iav zoo tib yam: feem ntau pom nyob rau hauv cov khoom lag luam iav txhua hnub, xws li iav khob thiab khob fwj. Tus number case rau kev luam ntawv zoo tib yam iav yuav tsum muaj cov dej tsis kam thiab tshuaj lom neeg tiv taus kom tau raws li kev tu thiab muaj cov khoom.

Borosilicate iav: muaj qhov zoo thermal thiab tshuaj ruaj khov, thiab feem ntau siv hauv kev kuaj cov cuab yeej kuaj thiab cov iav siab kawg. Ntxiv rau cov khoom lag luam dav dav, cov kua mem rau luam ntawv borosilicate iav kuj tseem muaj peev xwm tiv taus qee txoj kev kho kub kub siab.

Tempered iav: Siab zog thiab kev nyab xeeb zoo. Thaum luam tawm ntawm lub tshuab tempered, tus mem kua xav tau tiv thaiv qhov kub thiab kev nyuaj siab hloov thaum lub sijhawm ua kom muaj kev ncaj ncees thiab kev ruaj ntseg ntawm cov qauv luam tawm.

Hlau
Tinplate: feem ntau siv nyob rau hauv cov zaub mov tuaj yeem ntim tau. Tus number case siv los luam tawm cov ntawv yuav tsum muaj cov khoom zoo corrosion tsis kam thiab npau npau paug kom paub meej tias cov kua zaub yuav tsis paug cov zaub mov thaum lub sijhawm cia, thaum tus qauv tseem pom tseeb.

Aluminium phaj: siv tau dav hauv cov kaus poom dej, cov ntaub ntawv zoo nkauj, thiab lwm yam. Cov kua nplaum luam tawm ntawm lub ntsej muag zoo nkauj thiab huab cua kuj yuav yoog rau ib puag ncig uas sib txawv.

 

3. Cov neeg uas raug kaw rau cov inks

 

Lithographic luam ntawv
Luam ntawv lithographic siv lub hauv paus ntsiab lus uas roj thiab dej tsis tuaj yeem immiscible. Daim duab thiab cov kab lus ib feem yog roj-hlub thiab qhov khoob yog hydrophilic. Txoj kev luam ntawv no yog qhov tsim nyog rau cov luam tawm nrog cov ntawv luam loj thiab lwm yam kev hloov pauv kom ntseeg tau tias qhov number case hloov mus rau lub tshuab luam ntawv thiab ntawv thaum lub sij hawm luam ntawv.

 

Letterpress luam ntawv
Cov duab thiab cov ntawv sau ib feem ntawm cov ntawv luam ntawv siab dua yog qhov siab dua li qhov tsis muaj qab, thiab cov number case pauv mus rau substrate thaum lub tshuab luam ntawv. Letterpress luam ntawv feem ntau tau siv los luam tawm cov ntawv ua lag luam, thiab lwm yam. Hloov chaw siab kom ntseeg tau cov qauv luam tawm.

 

Lub zog luam ntawv
Daim duab thiab cov ntawv sau ib feem ntawm Gravure Printing yog qis dua li qhov tsis muaj qab, thiab tus number case tau sau nyob rau hauv lub qhov chaw rau luam ntawv. Gravation Printing yog tsim nyog rau kev lag luam zoo, xws li kev ua yeeb yaj kiab yas ua kom ntseeg tau tias tus number casing zoo nkauj kom paub meej tias tus number cas tuaj yeem qhuav sai thaum lub sij hawm nrawm luam ntawv yam tsis muaj smudging.

 

Vijtsam Luam Ntawv
Screen Printing siv ib daim scraper kom nyem qhov kua mem ntawm cov duab thiab cov ntawv sau thiab hloov nws mus rau substrate. Lub vijtsam luam ntawv muaj muaj zog yoog tau thiab tuaj yeem luam tawm ntawm subcosity ntawm ntau yam number case yuav tsum tau hais tias tus number case tau dhau los ntawm cov memes tuaj yeem dhau los ntawm cov memes tuaj yeem dhau los ntawm cov memes kom paub meej thiab tsim ib yam kev hnav khaub ncaws number case txheej ntawm substrate.

 

4.Txoj kev rau cov inks

 

Ntuj Kom Qhuav
Ntuj ziab cia ntawm lub ntuj volatilization thiab oxidation ntawm cov kuab tshuaj kom ua kom qhuav. Qhov kev ua kom qhuav no yooj yim thiab tus nqi qis, tab sis nws yog qhov tsim nyog rau cov khoom luam tawm kom qhuav, xws li cov khoom luam tawm tes. Kev ziab khaub ncaws kom qhuav yuav tsum tau xaiv cov kuab tshuaj uas muaj qhov tsis sib xws los xyuas kom muaj kev ruaj khov ntawm cov number case ntawm tus txheej txheem kom qhuav.

 

Cua sov cua sov
Cua sov qhuav ua kom nrawm nrawm nrawm nrawm nrawm ntawm cov kuab tshuaj nyob hauv cov kua zaub ntawm cov khoom luam tawm, yog li ua tiav kom qhuav kom qhuav. Cov hau kev ua hluav taws xob muaj xws li cov cua kub kom qhuav thiab ziab qhuav. Cua sov kom qhuav yog haum rau huab hwm coj cov khoom luam tawm, xws li ntim luam ntawv. Thaum cua sov thiab ziab, ua tib zoo saib xyuas cov cua sov kub thiab sijhawm kom tsis txhob muaj kev cuam tshuam ntawm cov khoom luam tawm lossis kev puas tsuaj rau cov number cas.

 

Ultraviolet Kom Qhuav
Ultraviolet qhuav siv ultraviolet tshav ntuj, yog li tus duab thaij duab ntawm monomers thiab prepolymers, yog li ua tiav kom qhuav. Ultraviolet kom qhuav yog ceev thiab txuag tau rau cov ntawv luam cov txheej txheem nrog kev ua kom qhuav heev kom muaj kev ceev ceev, xws li UV luam ntawv. UV Drying inks yuav tsum muaj cov duab yees duab thiab cov duab monomensitive monomers kom paub meej tias kev kho sai nyob rau hauv ultraviolet iradiation.

 

Hluav Taws Xob Nqaij Dej Kom Qhuav
Electron nqaij ua kom qhuav yog zoo ib yam li ultraviolet kom qhuav, thiab cov tshuaj tiv thaiv polymerization ntawm cov kua mem hluav taws xob. Electron Beam qhuav tau muaj lub zog siab dua, tuaj yeem kho tus cwj mem hauv lub sijhawm luv luv, thiab muaj cov ntawv nthuav dav dav dav rau cov number case. Txawm li cas los xij, tus nqi ntawm Electron Beam Daj Kom Qhuav Khoom yog qhov tseem ceeb, thiab nws yog tam sim no siv hauv qee qhov kev luam ntawv siab.

 

5.technical specifications ntawm inks

 

Xim
Xim yog ib qho ntawm cov txuj ci tseem ceeb tshaj plaws ntawm number case ntawm number case, uas ncaj qha cuam tshuam rau kev pom ntawm cov khoom luam tawm. Cov xim ntawm tus cwjpwm xav tau kom phim cov qauv xim lossis cov xim uas yuav tsum tau los ntawm cov qhua tuaj noj mov, thiab yog ntsuas raug thiab raug tswj tau los ntawm cov khoom siv xim.

 

Ua ke
Fineness hais txog qhov loj me ntawm cov pigment hais hauv number case, uas cuam tshuam txog fluidity thiab luam ntawv zoo ntawm number case. Tus me dua lub txiaj ntsig, cov finer cov ntawv luam ntawv nyhuv ntawm tus number case thiab lub meej meej tus qauv. Lub txiaj ntsig ntawm tus cwj mem tsis yog ntsuas los ntawm daim scraper fineness.

 

Viscosity
Viscosity reflets lub piscosity ntawm tus num viscosity ntawm number case thiab muaj ib qho tseem ceeb cuam tshuam rau kev hloov pauv thiab luam tawm cov khaub thuas ntawm tus cwj mem. Cov kev luam ntawv sib txawv yuav tsum muaj inks ntawm cov viscosities txawv. Piv txwv li, lub viscosity ntawm lithgrocic inks yog tus tseem ceeb, thaum lub viscosity ntawm gravure inks yog tsawg. Viscosity feem ntau ntsuas los ntawm ib tus vircais.

 

Kom Qhuav
Kom nrawm yog muaj feem xyuam rau cov neeg luam ntawv ntau lawm thiab cov khoom lag luam zoo. Kev nrawm nrawm nrawm nrawm yuav ua rau tsis muaj kev hloov pauv tsis zoo, thaum qeeb qeeb qeeb qeeb yuav cuam tshuam ntau dua thiab kuj tseem yuav teeb meem xws li pleev xim. Lub ziab ceev yuav tsum tau hloov kho raws li cov tib yam xws li kev luam ntawv, kev ziab thiab luam ntawv substrate.

 

Nplaum ceev ceev
Cov nplaum sai yog hais txog lub zog uas muaj zog ntawm number case ntawm number case number cas thiab luam tawm substrate. Zoo adhesion ceev nrawm yog tus yuam sij kom ntseeg tau tias tus number case tsis poob lossis ploj mus thaum siv cov khoom luam tawm. Cov nplaum nrawm nrawm yog feem ntau sim los ntawm cov hau kev xws li kev sim ntawm kev sib kis hla.
