Taw qhia
Epoxy kuab tshuaj raws li lub vijtsam number case tau tsim nrog cov khoom zoo epoxy resins rau zoo heev adhesion rau hlau, iav thiab ntau yam nyuaj-rau-luam substrates. Epoxy Ink Screen Printing yog qhov zoo tshaj plaws rau kev siv hluav taws xob thiab kev lag luam thiab muab cov kuab tshuaj zoo heev, tshuaj lom neeg thiab puas. Nws yog ob feem ntawm tus cwj mem thiab yuav tsum tau pib nrog lub catalyst ua ntej siv. Nws exhibited siab gloss tiav ua yog tsim nyog rau kev siv sab hauv tsev.
Substrates

Epoxy
Melamine
Kho polyethylene
Kho polypropylene
Tus number case tuaj yeem siv rau ntau lub substrates xws li hlau, ceramics, iav, phenolics, ureas, melamines thiab acrylics. Tshwj xeeb tshaj yog zoo rau cov enamels, kho polyethylene, polypropylene thiab qee cov polyesters.
Lawv yog ib tug ntau yam ntawm ob feem inks muaj zoo adhesion thiab tshuaj tiv thaiv. Lawv kho cov yeeb yaj kiab uas muaj zog tiv taus cua sov nrog zoo adhesion mus rau ntau yam nyuaj substrates. Cov inks no tuaj yeem ua rau cua qhuav lossis cua sov kho.
Nyob ntawm cov hardener xaiv, matt lossis tag nrho gloss tiav yuav tau txais.
Cov xim qhia yog rau kev taw qhia nkaus xwb - tsis yog rau xim txuam.
Solvent Based ink - Siv cov kuab tshuaj tiv thaiv emulsion.
CHAW UA HAUJ LWM & CHAW UA HAUJ LWM: Siv tsis pub dhau 1 xyoos yog pom zoo. Kev cia hauv lub tub yees yog qhia.
LUS CEEB TOOM: Rau tag nrho cov xim tshwj tsis yog nyiaj, sib tov 2 feem ntawm tus number case rau 1 feem catalyst los ntawm qhov hnyav. Rau cov nyiaj, sib tov 2.4 qhov chaw number case rau 1 feem catalyst los ntawm qhov hnyav. Cia lub sijhawm induction ntawm 30 min, kom ua tiav cov txiaj ntsig zoo tshaj plaws. Thaum siv nrog cov roj hmab stamp, yob tus number case mus rau nyias nyias ntawm lub khob, hlau lossis yas phaj nrog lub brayer roller los yog cov cuab yeej zoo sib xws ua ntej hloov mus rau lub stamp.
Khoom: Peb epoxy rau number case muaj superior adhesion rau epoxy, iav, hlau los yog lwm yam nonporous nto. Kev tiv thaiv zoo heev rau kev puas tsuaj, MEK, cawv, TCE, flux tshem tawm, ntsev, kua qaub thiab alkali daws thaum kho kom zoo. Tsim los rau roj hmab stamping lossis offset luam ntawv.

Ceev ceev
Lub adhesion ntawm tus cwj mem rau cov ntaub ntawv luam tawm feem ntau suav nrog kev siv tshuaj lom neeg, kev quab yuam intermolecular, cuam tshuam electrostatic force thiab mechanical force. Cov rog no yog muab los ntawm cov resin siv hauv kev luam ntawv thiab cov khoom siv substrate. Rau cov khoom sib txawv, nws yog ib qho tseem ceeb uas yuav tau siv cov resins sib txawv. Feem ntau hais lus, rau PE, PP thiab lwm yam uas tsis yog-polar substrates, txawm tias los ntawm kev kho mob corona, nws qhov nro tuaj yeem ncav cuag 38 Dyne lossis li ntawd. Hloov chaw, nws yuav tsum siv cov qauv tsis-polar resin xws li chlorinated polypropyl resin cov ntaub ntawv txuas; Rau PET, PA thiab lwm qhov chaw polarity substrate, polyurethane resin txuas cov khoom zoo dua.
Tinting peev xwm
Cov xim inorganic yog cov khoom siv yooj yim los muab cov xim rau tus number case, tab sis raws li tus number case adhesion ntawm qhov chaw, muaj qee qhov sib txawv ntawm cov xim qub. Yog vim li cas nyob rau hauv printing number case. Cov pigment particles tsis nyob ib leeg, tab sis tau tawg nyob rau hauv qhov sib txuas nruab nrab. Nyob rau hauv micro-theem, qhov zoo tshaj plaws wetting dispersion xeev ntawm ib tug pigment particle yog kiag li qhwv nyob rau hauv lub resin binder tusyees thiab txuas mus rau lub substrate nto. Cov zaub ntawm cov xim yog pom tau los ntawm kev xav: qhov teeb meem ntawm lub teeb xim ntawm cov xim coated mus los ntawm cov resin txuas cov khoom siv zaj duab xis txheej thiab xa mus rau cov neeg siv khoom lub qhov muag. Lub pob tshab ntawm peb cov epoxy resin thiab qhov loj ntawm cov xim tooj ncaj qha cuam tshuam rau kev qhia ntawm cov xim sib txawv. Nyob rau tib lub sijhawm, qhov txaus dispersion ntawm resin pigment ncaj qha cuam tshuam rau cov xim pigment ntim ntim thiab qhov zoo ntawm tus number case nws tus kheej.
Viscous kuj
Viscous resistance yog qhov ntsuas tseem ceeb hauv kev ntsuas tus cwj mem. Gravure luam ntawv yog ib txoj kev luam ntawv nrog cov ntawv sau ntau, cov kauj ruam zoo rov ua dua thiab nrawm nrawm. Cov inks siv nyob rau hauv nws feem ntau hnyav volatile drying inks. Tom qab lub tshuab luam ntawv number case hloov mus rau lub substrate, los ntawm txoj kev ziab, cov organic hnyav sai sai volatilizes tom qab ziab. Thaum mus los ntawm qhov kub-kub qhuav txoj kev tom qab rewinding, qhov kub ntawm lub tshuab luam ntawv yog feem ntau ntawm 40 degree ~ 60 degree, nyob rau tib lub sij hawm, vim lub muaj nyob ntawm rewinding siab, yog tus number case nws tus kheej tsis muaj anti zoo. -viscosity, nws yuav ua rau loj rewinding adhesion kev huam yuaj lossis teeb meem zoo.
