Printing Inks yog dab tsi?

Raws li peb txhua tus paub,tus cwj memyog ib qho kev sib xyaw ntawm cov xim ntawm lub cev (xws li pigments, dyes, thiab lwm yam), binders, filling (filling) cov ntaub ntawv, cov ntaub ntawv ntxiv, thiab lwm yam, uas tuaj yeem luam tawm thiab ziab ntawm lub cev.Nws yog slurry nplaum nrog ib tug xim thiab ib tug tej yam txaus degree.Yog li ntawd, xim (xiav), lub cev (thickness, ntws thiab lwm yam rheological zog) thiab kev ua kom qhuav yog tus cwj mem ntawm peb qhov kev ua tau zoo tshaj plaws.Lawv muaj ntau hom, lub cev lub cev tsis zoo ib yam, qee qhov tuab heev, nplaum heev, thaum lwm tus nyias nyias.Qee tus siv cov roj zaub ua cov ntawv khi, thiab qee qhov yog siv los ua cov ntawv khi nrog cov resins thiab cov kuab tshuaj lossis dej.Cov no yog ua raws li cov khoom luam tawm uas yog lub substrate, txoj kev luam ntawv, luam ntawv phaj hom thiab txoj kev ziab kom qhuav.

Muaj nuj nqi

Ink yog ib hom slurry nplaum nrog tej yam fluidity, viscosity, tsis zoo tus nqi, thixotropy, fluidity, dryness thiab thiaj li nyob rau tag nrho cov txiav txim qhov ua tau zoo ntawm tus number case.

viscosity

Nws yog ib qho cuab yeej uas tiv thaiv qhov ntws ntawm cov kua dej, ib qho kev ntsuas ntawm kev sib cuam tshuam ntawm cov kua dej molecules uas cuam tshuam cov kev txheeb ze ntawm nws cov molecules, uas yog, qhov tsis kam ntawm cov kua dej.

Yield nqi

Nws yog qhov tsawg kawg txav kev ntxhov siab yuav tsum tau coj cov kua dej kom pib ntws.

Fluidity

Hais txog tus cwj mem nyob rau hauv nws tus kheej lub ntiajteb txawj nqus, yuav ntws zoo li ib tug kua, los ntawm tus number case viscosity, yield tus nqi thiab thixotropy txiav txim siab, tib lub sij hawm luam ntawv number case thiab kub kuj tseem txuas nrog.

Kev sib xyaw

Pigment yog cov khoom muaj pes tsawg leeg ntawm tus number case, cov khoom siv xim xim, feem ntau insoluble hauv dej xim.Ink xim saturation, xim luam ntawv number case quab yuam, pob tshab thiab lwm yam kev ua tau zoo thiab xim xim muaj kev sib raug zoo.Lub binder yog cov kua dej ntawm tus number case, thiab cov xim yog cov cab kuj.Nyob rau hauv cov txheej txheem luam ntawv, lub binder nqa cov pigment particles, los ntawm cov luam ntawv xovxwm number case ib nrab ntawm tus number case roller, luam ntawv phaj, toss mus rau lub substrate los ua tus number case zaj duab xis, tsau, qhuav thiab glued rau substrate.Lub gloss, dryness, mechanical zog thiab lwm yam khoom ntawm tus number case zaj duab xis muaj feem xyuam rau kev ua tau zoo ntawm cov binder.

Qhov tseeb,luam ntawv inkstuaj yeem siv rau ntau lub sijhawm.Meanwhile, peb yuav tsum xyuam xim rau kev siv ntawm nws.
