Qhov kev sib txuas ntawm cov ntawv nyeem tseem muaj cov xim xim ntawm tus cwj pwm, uas yog ib lub npe rau kev xav txog cov teeb meem ntawm cov lej dispersion thiab qhov nyiaj ntawm cov xim hauv tus cwj mem. Uas yog hais, ntau dua qhov degree ntawm dispersion ntawm cov pigment, ntau dua cov concentration ntawm tus number case; qhov ntau dua cov xim cov xim hauv tus cwj pwm, qhov ntau dua nws cov concentration. Ntxiv rau cov pigment txiav txim siab cov concentration ntawm tus number case, cov binder, muab tub lim thiab additives, rau ib qho twg, kuj muaj qhov concentration ntawm tus number case. Cov txheej txheem ntau yam qhia tau hais tias cov ink concentration yog ib qho ntawm cov tseem ceeb ntawm kev cuam tshuam txog kev luam ntawv zoo. Yog li ntawd, kom to taub thiab to taub ntau ntau yam uas muaj feem xyuam rau cov ink concentration yog qhov tseem ceeb ntawm txoj kev tswj cov txheej txheem ntawm kev luam ntawv thiab kev txhim kho ntawm cov kev luam ntawv zoo ntawm qhov khoom.
Cov cwj mem yog ib co duab hydrophobic uas yog homogeneous sib xyaw ntawm cov pigments, khi, cov fillers thiab cov koom haum. Cov pigment yog xim xim teeb meem thiab plays lub luag haujlwm hauv kev xim xim hauv tus cwj mem. Nws yog xim dawb uas yog cov dej hauv cov dej thiab tsis siv nyob rau hauv cov pob khoom, tiam sis tuaj yeem ua rau lub cev tsis sib haum, thiab yog ib qho khoom powdery. Tus nqi ntawm cov xim hauv tus cwj pwm txiav txim siab qhov ua kom ntev thiab cov concentration ntawm tus cwj mem thiab nws tseem cuam tshuam rau kev ua kom zis ntawm tus cwj mem. Pigment, raws li cov khoom tseem ceeb ntawm kev loj hlob xim, plays lub decisive luag hauj lwm nyob rau hauv qhov zoo thiab haum ntawm tus number case. Yog li, rau cov luam yeeb, tsuas yog cov xim xim zoo nkauj, cov roj nqaim yog loj, lub qhov nqus yog me me, lub zog zais me me, lub hwjchim xim muaj zog, ruaj ntseg zoo, xim yog tsawg, xim yog , thiab lub cua kub tsis haum, lub teeb ua hauj, acid thiab alkali tsis kam, thiab lwm yam. Kev ua tau zoo, tus number case xim ntawm cov ntawv luam tawm tau tuaj yeem ua haujlwm zoo dua. Raws li cov khoom thiab cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov pigment, cov pigment yog cais ua ob hom: ib qho xim hauv cov xim thiab ib cov organic pigment. Cov pigments inorganic xws li hlau oxides, chromates, carbonates, sulfates, thiab sulfides, xws li txhuas hmoov, tooj liab hmoov, carbon dub, zinc dawb, thiab titanium dawb, tag nrho cov uas muaj rau qeb ntawm inorganic pigments. Cov pigments inorganic muaj qhov pom kev zoo thiab kev kub ntawm lub cev, thiab muaj lub zog loj thiab muaj zog zais, tab sis tsis haum rau ntau cov xim thiab luam tawm high-speed printing. Feem ntau siv cov organic pigments xws li chromogenic pigments thiab pas pigments. Chromogenic pigments yog cov phthalocyanine pigments, nitroso pigments, azo pigments thiab txo pigments. Pas dej pigments yog: cov pas dej qis, cov pas dej tsawg kawg nkaus thiab pas dej qias tuaj. Feem ntau cov organic pigments muaj zoo tinting zog, me me particle, lub teeb lub ntiajteb txawj nqus, mos kev ntxhib los mos, ci xim thiab siab concentration. Lawv yog cov ntaub ntawv tseem ceeb rau cov xim muaj xim. Lub binder tseem yog ib qho tseem ceeb ntawm tus cwj mem. Nws yog ib yam khoom raw uas ua rau tus number case kua. Nws muaj ib qho viscosity. Nws yog siv los sib xyaw thiab txuas cov khoom sib xws xws li powdery pigments, thiab hloov thiab ua raws li cov pigments. Nyob rau ntawm cov khoom luam tawm, cov ntawv luam tawm tau muaj qee cov gloss nyob rau tib lub sijhawm. Nws cov xim, nro, viscosity, dej ua hauj, dryness, thiab lwm yam. Yog yam tseem ceeb uas cuam tshuam cov kev ua tau zoo ntawm tus number case, thiab nws cov nyiaj tseem yog ib qho tseem ceeb rau kev hloov fluidity thiab concentration ntawm tus number case. Lub muab tub lim yog ib qho zoo, dawb powdery khoom siv, yog li nws yuav ua tau zoo thiab zoo dispersed nyob rau hauv lub binder. Potassium sulphate, magnesium carbonate, calcium carbonate thiab aluminium hydroxide yog tag nrho cov fillers uas ua kom kho cov ink number case inkiness, taub hau thiab concentration hauv tus number case. Tom qab cov pigment, cov phom tag thiab cov neeg muab khoom siv ua tiav rau hauv ib daim yuaj tiav lawm los ntawm qee tus nqi ntawm tus cwj pwm, tuab, tsaus thiab qhuav ntawm daim tseem cuav yuav tsis muaj peev xwm hloov tau ntau yam mob vim muaj kev luam tawm txawv. Nws yog feem ntau los ntawm kev siv qee cov khoom siv ntxiv, xws li cov tshuaj tiv thaiv, cov neeg ua haujlwm debonding, cov roj ntsha qhuav, cov roj ntsha thiab cov roj ntsha. Cov tshuaj ntxiv no yuav tau hloov cov ink numberation tom qab ntxiv rau tus number case.
Qhov concentration ntawm tus number case yog loj thiab nws cov taub hau kuj yog loj. Vim li no, qhov luaj li cas ntawm tus cwj pwm txiav txim siab qhov tob ntawm hawj ntawm tus number case. Thaum tus number case concentration loj, lub hawj luam tawm yog tob; nyob rau hauv tsis tooj, lub luam Hawj yog ntiav. Cov lej uas muaj cov ntsiab lus loj loj siv tsawg tus number case ntawm luam, thiab xim ntawm tus cwj pwm kuj zoo. Conversely, tus number case nrog lub me ntim siv ntau tus nqi ntawm tus number case thaum luam ntawv, thiab tus number case xim yog cov teeb. Cov concentration ntawm tus number case yog tshwj xeeb yog mas thaum luam ntawv loj cov khoom phaj. Nws tuaj yeem pom tau tias tus number case concentration ncaj qha cuam tshuam rau cov luam ntawv zoo ntawm qhov khoom. Yog li, thaum luam ntawv zoo mesh lossis nyias cov khoom, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov cwj mem ntau ntau ntawm cov zauv los luam tawm, txawm tias cov ntawv tsim tawm yuav tsim nyog rau qhov tsawg dua. Tus number case yog luam tawm. Vim tias tus number case muaj "thixotropy" sab, thaum lub chaw sov siab kub, siab ceev ceev, tus number case yog rhuab thiab thinned, thiab cov concentration ntawm nws yog txo, uas yuav tsum tau luam tawm nrog me ntsis siab concentration number, uas zoo dua xyuas kom xim ntawm cov khoom. zoo. Conversely, number case nrog tsawg dua concentration yuav siv tau rau luam ntawv. Yog tias tus number case nrog lub me me concentration yuav siv los luam cov keeb kwm xim lossis cov xim palette, nws yuav tsum ua kom tus lej ntawm qhov tsim kom tau lub siab nyiam hawj, tab sis qhov no tuaj yeem ua rau cov khoom siv tsis raug. Raws li qhov teeb meem no, tus number case uas siv rau hauv cov xim luam tawm feem ntau txais kev kho ntawm cov Hawj ntawm cov xim, thiab cov concentration kuj tsim nyog kho, cov nyhuv luam tawm zoo, thiab cov tshuaj tua tsis tau ntawm cov khoom luam yog facilitated . Tsis tas li ntawd, luam tawm ib qhov loj ntawm cov qauv tsim, kab version lossis cov qauv tshev, kev ceev ceev yuav tsum tau kho me ntsis qeeb qeeb, kom txo tau kev txhuam coefficient thiab thaum tshav kub hauv kev luam ntawv, los tiv thaiv qhov kub ntawm kev tawm sai , yog li ntawd tus number case yog yooj yim rau nyias nyias Qhov nce hauv kev sib deev ua rau txo qhov concentration, thiab qhov tsis zoo ntawm kev sib zog ntawm tus kheej dua luam ntawv.
Txoj kev xyaum thiab kev tshuaj ntsuam pom tau hais tias cov concentration ntawm thawj tus cwj mem yog qhov ruaj khov thaum nws tsis siv, tab sis cov concentration hloov nrog cov variation consistency thiab fluidity thaum siv. Cov kev hloov hauv kev ceev ceev, qhov kub thiab txias, thiab qhov nyiaj dampening yuav muaj feem xyuam rau lub inking concentration. Yog hais tias lub voj nyob rau hauv cov txheej txheem luam ntawv loj loj, tus number case concentration yuav tsum tau diluted, thiab tus number case xim yuav pom daj ntseg. Nws tuaj yeem pom tau hais tias cov ink concentration yog qhov sib txawv ntawm qhov cuam tshuam uas muaj feem xyuam rau qhov zoo ntawm cov xim ntawm cov khoom. Yog li ntawd, nws yog ib qho tseem ceeb uas tseem ceeb rau kev nkag siab thiab paub txog qee qhov kev mob uas muaj feem xyuam nrog cov number case concentration thiab kev txais kev ua haujlwm kev ntsuas rau kev luam.
