Peb pom ntawm txoj kev cov yeeb yuj nplua nuj, qhov tseeb loj-hom ntawv tshaj tawm, yog cov duab tshuab luam ntawv.Thiab raws li kev siv sib txawv peb siv tus cwj mem tsis zoo ib yam, hnub no xiaobian muab koj cov lus piav qhia yooj yim ntawm lub tshuab pictorial nrog number case a ob peb qhov sib txawv:
Lub tshuab yees duab feem ntau yog siv rau oily number case pigment dilution hauv cov roj, xws li cov roj ntxhia, roj zaub, number case ntawm cov luam ntawv nruab nrab los ntawm cov roj nkag thiab evaporation pigment txuas mus rau nruab nrab; Dej raws li tus number case yog dej raws li qhov nruab nrab dispersion, number case ntawm lub tshuab luam ntawv nruab nrab los ntawm infiltration thiab evaporation ntawm dej pigment txuas mus rau nruab nrab.
Diam duab kev lag luam number case raws li kev siv kom paub qhov txawv, tuaj yeem muab faib ua ob hom:Ib qho yog dej-raws li number case, uas yog tsim los ntawm dej thiab dej-soluble solvents.
Lwm qhov yog, oily number case, insoluble hnyav raws li lub ntsiab tivthaiv ntawm yaj xim puag.
Raws li solubility ntawm cov kuab tshuaj, nws tseem tuaj yeem muab faib ua peb hom:
Ua ntej, dye number case: nws yog dye raws li tus number case, feem ntau siv cov tshuab yees duab sab hauv tsev;
Ob, pigment number case: nws yog raws li xim number case, siv rau sab nraum zoov luam ntawv tshuab.
Peb, tsis muaj zog hnyav number case: nruab nrab ntawm ob, siv rau sab nraum zoov yees duab tshuab.
Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tseeb tias peb cov inks tsis tuaj yeem siv ua ke.Lub tshuab ua dej tsuas tuaj yeem siv cov kua dej raws li tus cwj mem,thiab roj-raws li tshuab tsuas tuaj yeem siv cov kuab tshuaj tsis muaj zog thiab cov kuab tshuaj hnyav.Txij li thaum tus number case cartridge, yeeb nkab thiab nozzle ntawm lub tshuab siv dej thiab roj-raws li lub tshuab sib txawv thaum lub tshuab raug teeb tsa, tus number case tsis tuaj yeem siv random.
Cov yam ntxwv cuam tshuam rau qhov zoo ntawm tus number case feem ntau muaj tsib yam: dispersant, conductivity, PH nqi, nto nro, viscosity.
1) Dispersant:yog ib tug surfactant, nws lub luag hauj lwm yog los txhim kho lub cev lub cev ntawm tus number case nto, txhim khu cov affinity ntawm number case thiab daim txhuam cev, noo noo.Yog li feem ntau los ntawm daim txhuam cev cia, conduction ntawm tus number case muaj dispersants.
2) Hluav taws xob conductivity:tus nqi no yog siv los cuam tshuam nws cov ntsiab lus ntsev.Zoo zoo inks yuav tsum tsis txhob muaj ntau tshaj 0.5% ntsev kom tsis txhob crystallization ntawm lub nozzle.Oily number case raws li particle loj ntawm cov xim, txiav txim siab siv dab tsi nozzle, loj tshuaj tsuag tshuab 15PL, 35PL yog raws li qhov loj me los txiav txim qhov tseeb ntawm lub tshuab inkjet, qhov no tseem ceeb heev
3) PH tus nqi:hais txog cov kua PH, cov kua qaub ntau dua, qhov PH tus nqi qis dua, ntawm qhov tsis sib xws, cov tshuaj alkaline ntau dua, tus nqi PH ntau dua.In thiaj li tiv thaiv tus number case corrosion nozzle, PH tus nqi feem ntau yuav tsum nyob nruab nrab ntawm 7- 12.
4) nto nro:tuaj yeem cuam tshuam rau kev tsim cov kua dej hauv cov kua dej, cov cwj mem zoo yog qhov tsis muaj viscosity, siab ntom ntom ntom.
5) viscosity:uas yog, qhov tsis kam ntawm cov kua dej, qhov viscosity ntawm tus number case loj dhau, yuav ua rau cov txheej txheem luam ntawv ntawm tus number case mov.
cuam tshuam; viscosity tsawg dhau, yuav tsim cov kua dej ntws hauv cov txheej txheem luam ntawv.Ink nyob rau hauv ib chav tsev kub, feem ntau yuav khaws cia rau 3-6 lub hlis, ntev dhau los nag lossis daus, thiab cuam tshuam rau kev siv los yog ntsaws, number case preservation yuav tsum tau kaw, tsis txhob ncaj qha tshav ntuj, kub yuav tsum tsis txhob siab dhau heev lawm los yog tsawg heev.
