Peb lub neej muaj ntau yam ntaub ntawv luam tawm, khaub ncaws, ntawv xov xwm, thiab ntim txhua yam.Raws li cov neeg muag khoom ntim khoom noj khoom haus thiab cov neeg siv khoom, peb muaj kev txhawj xeeb tshaj plaws txog cov cwj mem zoo li cas yog tus phooj ywg zoo thiab tsim nyog rau kev lag luam ntim khoom noj.Nyob rau hauv tsab xov xwm no, peb yuav qhia koj txog ib puag ncig tus phooj ywg tus cwj mem zoo dua rau kev ntim khoom noj khoom haus: dej-raws li number case.

Lub tswv yim ntawm Water-Based Ink
Ib txoj kev tshawb fawb yog siv los tsim qhov no hu ua dej-raws li tus cwj mem, uas feem ntau siv dej ua cov kuab tshuaj.Dej-raws li number case thiab lwm yam luam ntawv inks tsis muaj teeb meem rau kev noj qab haus huv ntawm lub tshuab luam ntawv tus neeg teb xov tooj piv rau lawv cov non-volatile, lom organic solvents.Cov ntawv luam tawm kuj yog ib puag ncig zoo.Tus cwj mem tsis tsuas yog muaj cov khoom tsis muaj nplaim taws, tab sis nws kuj tshem tawm qhov kev hem thawj ntawm kev kub hnyiab thiab tawg hauv lub rhiav luam ntawv, uas yog qhov zoo rau kev ua haujlwm nyab xeeb.Ntawm chav kawm, tus cwj mem thiab tus cwj mem tam sim no muaj ntau yam kev siv: offset luam ntawv number case, flexographic luam ntawv number case, thiab gravure printing number case.In Europe, America, Nyiv, thiab lwm lub teb chaws industrialized, number case tau tsis tu ncua supplanted number case, nrog rau offset printing sab nraum lub cim number case lwm txoj kev luam ntawv.Hauv Tebchaws Meskas, piv txwv li, 95% ntawm flexographic prints thiab 80% ntawm gravure prints muaj number case.
Ntxiv nrog rau kev tiv thaiv ib puag ncig, nws yog dav siv nyob rau hauv lub ntiaj teb no ntawm dej number case vim nws superior kev kawm: number case xim stability, siab brightness, muaj zog coloring zog, ib tug tsis-corrosive phaj, muaj zog adhesion tom qab luam ntawv, adjustable ziab ceev, dej tsis kam. , plaub-xim overprinting, chaw-xim luam ntawv, thiab lwm yam.Kev tsim thiab siv dej number case hauv Suav teb pib lig, tab sis kev nce qib tau nrawm, tshwj xeeb tshaj yog nyob rau xyoo tas los no, uas tau ua rau muaj kev loj hlob sai.Qhov zoo ntawm domestic number case tau nce nyob rau hauv tandem nrog qhov nce nyob rau hauv kev thov rau number case.Ink, nyob rau hauv ib txwm kev xav ntawm sluggish qhuav, tsis zoo gloss, tsis muaj dej tsis kam, phony printing, thiab lwm yam flaws, tau zoo heev.Tus nqi rau tus cwj mem txawv teb feem ntau yog siab heev, tab sis Suav tus number case tau dhau los ua lag luam nrog nws cov qauv zoo nkauj thiab pheej yig. Tus nqi rau cov number case txawv teb chaws feem ntau yog siab heev, tab sis Suav number case tau dhau los ua lag luam nrog nws cov qauv zoo nkauj thiab pheej yig.
Xav txog cov khoom thiab muaj pes tsawg leeg ntawm Dej-raws li Ink.
Dej-raws li tus number case yog tsim los ntawm cov dej-soluble resin, sophisticated pigments, kuab tshuaj, thiab additives uas tau pulverized los ntawm scientific composite ua.Cov dej-soluble resin hauv tus number case feem ntau yog cov khoom sib txuas, dispersing pigment particles uniformly kom tus number case muaj ib qho kev txav mus los thiab adhering rau cov khoom siv substrate kom tus number case tuaj yeem tsim ib txheej txheej zaj duab xis tom qab luam ntawv.Cov xim ntawm tus cwj mem yog feem ntau txiav txim siab los ntawm cov xim, uas sib npaug ntawm cov khoom sib txuas raws li cov khoom sib txuas, thiab cov xim xim tuaj yeem nqus, cuam tshuam, thim rov qab, thiab xa lub teeb, tso cai rau lawv tso saib cov xim tshwj xeeb. Cov xim yuav tsum muaj cov xim zoo nkauj, xim txaus thiab npog lub zog, thiab muaj kev sib cais siab.Tsis tas li ntawd, nyob ntawm kev siv, lawv tuaj yeem muaj qhov sib txawv abrasion resistances.Cov kuab tshuaj txoj haujlwm yog kom yaj cov resin kom tus number case muaj qee qhov fluidity, kev hloov pauv yuav tshwm sim zoo nyob rau hauv cov txheej txheem luam ntawv, thiab cov viscosity thiab ziab ntawm cov number case tuaj yeem hloov kho.Cov kuab tshuaj nyob rau hauv dej-raws li tus number case feem ntau yog dej nrog me ntsis ntawm ethanol.
Dej-raws li Ink feem ntau siv Additives xws li Raws li Defoamer, PH Tus nqi Stabilizer, Slow Drying Agent, thiab lwm yam.
(1) defoamer.Lub luag hauj lwm ntawm lub defoamer yog inhibit thiab tshem tawm cov tiam ntawm huab cua npuas.Feem ntau hais lus, thaum lub viscosity ntawm cov dej-raws li number case siab dhau lawm, PH tus nqi qis dhau lawm, los yog lub tshuab luam ntawv khiav ceev kuj ceev, nws yooj yim los tsim npuas.Yog tias tus naj npawb ntawm cov npuas uas tsim los kuj loj heev, yuav muaj cov xim dawb, xim tsis sib xws, uas yuav cuam tshuam rau qhov zoo ntawm cov ntawv luam tawm.
(2) tus neeg saib xyuas kom qhuav.Tus neeg saib xyuas kom qhuav qeeb tuaj yeem cuam tshuam thiab ua kom qeeb qeeb ntawm kev ziab ntawm cov dej raws li tus number case los tiv thaiv tus number case hauv cov ntawv luam ntawv lossis anilox rollers los ntawm kev ziab thiab txo qhov tshwm sim ntawm kev thaiv thiab muab tshuaj txhuam luam ntawv tsis raug.Tswj tus nqi ntawm tus neeg saib xyuas kom qhuav;Feem ntau, tag nrho cov number case yuav tsum nyob nruab nrab ntawm 1% thiab 2%.Yog tias koj ntxiv ntau dhau, tus number case yuav tsis qhuav kom huv si, thiab cov ntawv luam tawm yuav nplaum, qias neeg, lossis ua rau muaj ntxhiab tsw phem.
(3) PH tus nqi stabilizer:PH tus nqi stabilizer feem ntau yog siv los tswj thiab tswj PH tus nqi ntawm cov kua dej raws li tus lej kom nws ruaj khov nyob rau hauv thaj tsam ntawm 8.0-9.5.Nyob rau tib lub sijhawm, nws tseem tuaj yeem tswj cov viscosity ntawm cov kua dej raws li tus lej thiab tus lej dilution.Feem ntau hais lus, tus nqi tsim nyog ntawm PH stabilizer yuav tsum tau ntxiv txhua lub sijhawm ntawm cov txheej txheem luam ntawv kom cov dej-raws li tus cwj mem nyob rau hauv zoo luam ntawv.
Environmental friendliness ntawm dej-raws li number case
Dej-raws li tus cwj mem raws li kev tiv thaiv ib puag ncig, cov khoom muaj cov khoom tsis muaj tshuaj lom, tsis muaj corrosive, tsis muaj ntxhiab tsw, tsis yog nplaim taws, tsis tawg, muaj kev ruaj ntseg zoo, yooj yim rau kev thauj mus los, muaj siab concentration, tsawg. ntau npaum, tsis tshua muaj viscosity, zoo adaptability rau luam ntawv, ruaj khov kev ua tau zoo, ceev ceev rau adherence, ceev kom qhuav, dej, alkali, thiab abrasion kuj ua tau zoo heev;Cov qauv luam ntawv nyuaj kuj tseem tuaj yeem ua tiav cov qib nplua nuj, cov xim ci ntsa iab thiab zoo nkauj, thiab lwm yam zoo.Qhov txiaj ntsig tseem ceeb ntawm kev siv dej raws li tus cwj mem yog tias nws txo qis cov organic volatiles (voc) tso tawm rau hauv qhov chaw, uas yuav pab txhim kho. luam ntawv tej yam kev mob, zam kom tsis txhob muaj kuab paug huab cua, thiab txo qhov kev pheej hmoo ntawm hluav taws.Txhawm rau txhim kho qhov zoo ntawm ib puag ncig, nws tuaj yeem tshem tawm tag nrho qee qhov teeb meem uas cov kuab tshuaj raws li cov kuab tshuaj muaj rau tib neeg noj qab haus huv, nrog rau cov pa phem uas tuaj nrog ntim.Nws ua haujlwm tshwj xeeb zoo rau kev luam ntawv thiab ntim cov khoom uas yuav tsum tau ua kom huv si, xws li zaub mov thiab tshuaj.
Raws li tus neeg muag khoom lub khob khob, GFP ib txwm tau cog lus los siv cov khoom siv hauv eco hauv nws cov khoom, ua lub luag haujlwm rau ib puag ncig thiab kev noj qab haus huv ntawm nws cov neeg siv khoom.Peb cov khob ntawv yog luam tawm siv cov dej-raws li inks, thiab cov txheej txheem luam ntawv yog ua tiav ua ntej lub khob laminated, yog li thaum lawv siv, tus number case los ntawm sab nraud yuav tsis rub tawm sab hauv phab ntsa ntawm lub khob, ntxiv kev tiv thaiv kev noj qab haus huv. cov neeg siv.Thov mus saib qhov txuas hauv qab no kom paub ntau ntxiv txog peb cov khob ntawv ib puag ncig thiab lwm yam kev siv.
