Printing khoom compatibility: Hloov mus rau cov dej-raws li inks tej zaum yuav xav tau kev hloov kho lossis hloov kho rau cov khoom siv luam ntawv uas twb muaj lawm kom hloov mus rau cov yam ntxwv ntawm cov inks dej. Txhawm rau daws cov teeb meem no, cov kws tshawb fawb thiab cov kws tsim qauv txuas ntxiv txhim kho cov qauv ntawm cov dej-raws li tus cwj mem, txhim kho nws cov kev ua tau zoo, tab sis kuj tseem nyob rau hauv cov tshuab luam ntawv thiab cov cuab yeej siv tshiab, txhawm rau hloov kho kom zoo dua rau cov yam ntxwv ntawm cov dej-raws li number case. Tsis tas li ntawd, kev xaiv cov substrates tsim nyog thiab cov txheej txheem pretreatment kuj yog qhov tseem ceeb los xyuas kom meej cov txiaj ntsig luam ntawv zoo ntawm cov dej hauv dej.

Hauv qab no, kuv xav qhia peb qhov teeb meem hauv tus cwj mem thiab ntxuav cov txheej txheem.

Yam dab tsi cuam tshuam rau kev ziab nrawm ntawm cov dej hauv cov dej?

Dab tsi ua rau cov dej ua kua dej los ntshav ntawm daim ntawv?

Puas yog dej-based number case ruaj khov? Yuav ua li cas tiv thaiv tsis sib xws xim qhov tob?

Yam dab tsi cuam tshuam rau kev ziab nrawm ntawm cov dej hauv cov dej?

Kev ziab nrawm ntawm cov kua dej raws li tus cwj pwm yog hais txog lub sijhawm xav tau kom qhuav tom qab tus number case raug xa mus rau substrate. Yog tias tus number case dries sai heev, nws yuav qhuav thiab maj mam sib sau rau ntawm daim ntawv luam ntawv thiab anilox cov menyuam, thiab tuaj yeem thaiv cov menyuam anilox, uas ua rau poob lossis kev puas tsuaj ntawm halftone dots thiab dawb to ntawm qhov chaw. Lub tshuab ziab khaub ncaws nrawm dhau qeeb, hauv ntau xim overprinting yuav ua rau rov qab nplaum qias neeg. Nws tuaj yeem hais tau tias qhov ziab nrawm yog qhov tseem ceeb rau kev txiav txim siab luam ntawv zoo ntawm cov kua dej raws li tus number case. Txij li thaum ziab ceev yog qhov tseem ceeb heev, dab tsi yog qhov cuam tshuam rau kev ziab ceev ntawm cov kua dej raws li tus number case?

PH tus nqi, PH tus nqi yog hais txog cov alkali tsis kam ntawm cov kua dej raws li tus number case, uas yog ib qho tseem ceeb rau kev txiav txim siab tus cwj mem dej thiab luam tawm. Yog tias PH tus nqi ntawm cov kua dej raws li tus lej siab dhau lawm, qhov muaj zog alkalinity dhau lawm yuav cuam tshuam rau kev ziab ceev ntawm tus number case, uas ua rau qias neeg rov qab thiab dej tsis zoo. Yog tias tus nqi PH tsawg dhau thiab cov alkalinity tsis muaj zog heev, cov viscosity ntawm tus number case yuav nce thiab qhov ziab yuav sai dua, uas yuav ua rau muaj kev tsis xws luag xws li qias neeg, uas yuav yooj yim ua. Raws li ib txwm muaj, peb yuav tsum tswj hwm tus nqi pH ntawm dej raws li tus cwj mem ntawm 8.0 thiab 9.5.

2, qhov chaw luam ntawv, ntxiv rau tus number case nws tus kheej, yuav ua li cas peb luam tawm sab nraud ib puag ncig kuj tseem cuam tshuam rau kev ziab nrawm ntawm cov dej raws li tus number case, xws li qhov kub thiab av noo ntawm lub tshuab luam ntawv rhiav cuam tshuam qhov ziab ceev ntawm dej raws li number case. , tus txheeb ze av noo nce mus txog 95% Piv nrog rau 65%, lub sij hawm ziab yog yuav luag 2 zaug sib txawv. Nyob rau tib lub sijhawm, qhov cua qhov chaw yuav cuam tshuam rau qhov ziab nrawm ntawm cov kua dej raws li tus cwj mem. Qhov ntsuas qhov cua yog qhov zoo, qhov ziab nrawm nrawm, qhov cua tsis zoo, thiab ziab nrawm nrawm.

Lub substrate, ntawm chav kawm, ntxiv rau ob qho saum toj no, cuam tshuam los ntawm PH tus nqi ntawm lub substrate nws tus kheej thaum cov dej-raws li number case luam tawm rau saum npoo ntawm substrate. Thaum daim ntawv yog acidic, tus coupling tus neeg sawv cev siv los ua ib tug drier nyob rau hauv cov dej-raws li number case tsis ua hauj lwm, thiab cov alkali nyob rau hauv cov dej-raws li number case yog neutralized mus ua kom qhuav. Thaum daim ntawv yog alkaline, cov dej-raws li number case dries maj mam, uas qee zaum txwv cov dej raws li tus cwj mem kom ua tiav cov dej tsis kam. Yog li ntawd, tus nqi pH ntawm cov khoom siv substrate tseem yuav cuam tshuam rau kev ziab nrawm ntawm cov dej raws li tus number case. Tau kawg, ntxiv rau peb lub ntsiab lus saum toj no, muaj lwm yam tseem ceeb uas yuav cuam tshuam rau kev ziab nrawm ntawm cov dej raws li inks, xws li cov txheej txheem stacking ntawm substrates, thiab lwm yam, ntawm no peb yuav tsis ua cov lus qhia ntxaws.

Dab tsi ua rau cov dej ua kua dej los ntshav ntawm daim ntawv?

Dab tsi yog vim li cas rau dej-raws li staining ntawm daim ntawv? Thaum xav txog qhov teeb meem ntawm dej-raws li staining, xav txog nws los ntawm peb yam hauv qab no:

Muaj qhov sib txawv loj ntawm tus cwj mem thawj thiab hloov tus cwj mem.

① Yog tias nws yog tus number case qub, xav txog seb nws puas tau tas sij hawm los yog khaws cia ntev. Ob qho xwm txheej no yuav cuam tshuam rau sedimentation ntawm number case pigment. Txoj kev daws teeb meem yog co co tus number case cartridge ntawm chav tsev kub hauv qab 10 degrees Celsius kom cov xim tuaj yeem sib xyaw ua ke.

② Yog tias nws tshwm sim los ntawm kev hloov tus cwj mem, muaj ntau yam laj thawj. Nws feem ntau yog teeb meem nrog qhov piv ntawm cov dej los yog diluent ntxiv thaum lub sij hawm tsim khoom. Tus kheej, tsis muaj kev daws teeb meem rau qhov teeb meem no. Sim siv txoj kev hais saum toj no ua ntej thiab cia siab tias nws tsuas yog cais cov xim.

Cov teeb meem ntawv feem ntau muab faib ua cov thawv ntawv coated thiab cov ntawv tsis muaj coated (yuav tsum siv cov ntawv sab hauv tsev, sab nraum zoov ntawv dej-raws li number case tsis tuaj yeem kho xim)

① Tsis muaj dab tsi hais txog cov ntawv tsis muaj coated. Txawm hais tias nws yog daim ntawv dawb loj tshaj plaws uas tsis nyiam dej-raws li tus cwj mem, yog tias nws tsis yog hom coated, yuav muaj qee qhov tsis pom. Kev daws yog siv cov ntawv coated.

② Coated ntawv, lub ntsiab xav txog seb daim ntawv puas tau ntub dej, tau tas sij hawm, kev siv cov txheej yog nyias nyias hom, txawm li cas los xij yuav ua rau cov ntawv txheej sib xyaw tsis tuaj yeem ua rau kev tiv thaiv saum npoo, nruab nrab. xim tawv, cov dej hauv qab seepage, thiab nws thiaj li ua rau tawg. Tsuas yog cov kev daws teeb meem rau kev khaws cia ntawm daim ntawv yob yog hais tias thawj corrugated ntawv ntim lub thawv thiab cov yas ntim hauv yuav tsum tsis pub, thiab cov ntawv tsis siv yuav tsum muab rov qab.

Cov khoom siv teeb meem consumables. Lub taub hau luam ntawv yuav siv sij hawm ntev heev rau lub hnub nyoog, ua rau tsis sib xws ntawm tus number case faib thiab tawg paj. Siv cov khoom sib txawv lossis cov npe ntawm tus cwj mem los sib xyaw cov inks nrog cov tshuaj sib txawv hauv lub taub hau luam ntawv. Software, siv tus tsav tsheb lossis RIP software los luam tawm, tsis tau xaiv cov ntawv sib xws, ua rau muaj ntau lub dav hlau number case ntau tshaj qhov txwv uas daim ntawv tuaj yeem nqus dej noo, yog li ua rau tawg.

Puas yog dej-based number case ruaj khov? Yuav ua li cas tiv thaiv tsis sib xws xim qhov tob?

Dej-raws li inks, tseem hu ua dej-soluble los yog dej-dispersible number case, yog abbreviated li "dej thiab number case". Dej-raws li inks yog tsim los ntawm dissolving los yog dispersing siab molecular resin soluble nyob rau hauv dej, colouring agents, surfactants thiab lwm yam additives los ntawm cov txheej txheem tshuaj thiab lub cev ua.

Dej-raws li tus number case muaj ib qho me me ntawm cov dej cawv ua cov kuab tshuaj, ink stability. Yog li ntawd, nws yog tshwj xeeb tshaj yog haum rau ntim kev lag luam xws li zaub mov thiab tshuaj. Cov kua dej ua kua dej tuaj yeem ntxuav nrog dej, tsis muaj nplaim taws, tsis tawg, tsis muaj kev cuam tshuam rau huab cua puag ncig thiab kev noj qab haus huv ntawm cov neeg ua haujlwm, thiab tsis muaj hluav taws kub hnyiab los ntawm hluav taws xob zoo li qub thiab cov kuab tshuaj tua hluav taws, nrog rau kev nyab xeeb ntawm kev tsim khoom.

Dej-raws li tus number case yog ib hom tshiab luam ntawv number case nrog cov xim siab, tsis soluble, zoo gloss, muaj zog printability, zoo leveling thiab siab cov ntsiab lus. Dej-raws li number case yog yooj yim rau kev khiav lag luam. Thaum luam ntawv, tsuas yog raws li qhov xav tau ua ntej ntxiv cov neeg siv dej xa tawm zoo number case. Nyob rau hauv cov txheej txheem luam ntawv, qhov tsim nyog tus number case tshiab yog ntxiv ncaj qha, thiab tsis tas yuav muaj cov kuab tshuaj ntxiv, uas tuaj yeem tiv thaiv cov xim sib txawv. Dej-raws li tus number case feem ntau tsis yaj hauv dej tom qab ziab lawm. Thaum pib luam ntawv, lub phaj luam ntawv yuav tsum tau muab tso rau hauv dej raws li tus cwj mem kom tig, txwv tsis pub cov dej raws li tus cwj mem ntawm lub phaj luam ntawv yuav qhuav sai, ua rau lub phaj cov menyuam raug thaiv thiab tsis tuaj yeem luam tawm. Raws li qhov nce nqi ntawm cov kuab tshuaj organic tshwm sim los ntawm kev txo qis ntawm cov khoom siv roj av, cov nqi tsim khoom thiab kev siv ib puag ncig tus nqi ntawm cov kuab tshuaj hnyav yuav nce ntxiv ib hnub. Cov kuab tshuaj ntawm dej-raws li tus cwj mem feem ntau yog siv cov dej kais dej, thiab vim muaj cov kua dej ntau ntawm cov kua nplaum, qhov tob ntawm gravure phaj tuaj yeem ua rau ntiav.

Yog li ntawd, los ntawm tus nqi saib, txawm hais tias cov dej-raws li inks yog kim, lawv cov nqi siv tag nrho yog kwv yees li 30% qis dua cov kuab tshuaj raws li cov kuab tshuaj. Kuj tseem muaj kev txhawj xeeb tsawg dua txog cov tshuaj lom ntawm cov kuab tshuaj ntawm cov ntawv luam tawm. Kev ua tiav daim ntawv thov kev tshawb fawb ntawm dej-raws li inks hauv yas gravure luam ntawv tau undoubtedly coj xov xwm zoo rau xim luam ntawv ntim factories.
