Dej-raws li number case tshuab luam ntawv Hoobkas ntseeg hais tias muaj kev sib nrig sib attraction ntawm dej-raws li number case thiab substrates, thiab tus number case zaj duab xis yuav ruaj khov adsorbed rau ntawm lub substrate. Rau cov ntawv substrates, dej-raws li tus cwj mem tuaj yeem nkag mus rau hauv lawv qhov khoob thiab ua raws li "cov nyhuv anchoring"; rau substrates nrog du thiab tsis-absorbent nto, lub adhesion ntawm dej-raws li number case nyob ntawm qhov affinity ntawm dej-raws li number case thiab substrate molecules.

Dej-raws li number case tshuab luam ntawv Hoobkas ntseeg hais tias raws li lub sij hawm qhuav nce, cov adhesion ntawm cov dej raws li tus number case maj mam nce mus rau tus nqi loj, tab sis tom qab ntawd cov adhesion maj mam txo mus rau xoom, thaum lub sij hawm tus number case zaj duab xis nto yog du thiab qhuav thiab poob adhesion. Yog li ntawd, qhov zoo tshaj plaws overlay luam ntawv yuav tsum tau nqa tawm thaum lub viscosity siab, uas yog, thaum cov dej-raws li number case yuav qhuav. Vim tias cov kua dej ua kua dej yog dej-resistant, nws tuaj yeem tov nrog dej ua ntej ziab, thiab thaum nws qhuav, nws tsis tuaj yeem yaj hauv dej ntxiv lawm. Yog li ntawd, tsis txhob cia cov dej-raws li tus cwj mem qhuav ntawm cov menyuam anilox kom tsis txhob txhaws qhov inking qhov ntawm cov menyuam anilox. Tsis tas li ntawd, thaum lub sij hawm luam ntawv, lub phaj flexographic yuav tsum ib txwm moistened nrog tus cwj mem kom tsis txhob txhaws cov duab thiab cov ntawv ntawm lub phaj luam ntawv tom qab tus number case dries.

Water-based number case tshuab luam ntawv Hoobkas ntseeg hais tias kev luam tawm ntawm cov kua dej raws li tus cwj pwm tseem ceeb heev thiab muaj kev cuam tshuam rau cov txheej txheem luam ntawv thiab luam ntawv zoo, feem ntau suav nrog cov ntsuas kev ua tau zoo xws li viscosity, thixotropy, adhesion, thiab pH tus nqi.

Viscosity yog hais txog kev muaj peev xwm ntawm cov kua roj ntsha molecules kom nyiam ib leeg thiab cuam tshuam kev txav ntawm cov molecules. Nyob rau hauv cov txheej txheem luam ntawv, viscosity ntawm dej-raws li tus number case yog qhov tsim nyog rau kev tswj xyuas qhov kev hloov pauv thiab hloov ntawm tus number case. Cov yam tseem ceeb cuam tshuam rau cov viscosity ntawm dej-raws li number case feem ntau suav nrog cov hauv qab no.

(1) Lub viscosity ntawm lub binder. Rau inks siv tib cov xim, lub viscosity ntawm cov ntaub ntawv yog loj thiab cov viscosity ntawm tus number case kuj loj.

(2) Qhov loj, cov ntsiab lus thiab dispersibility ntawm cov xim pigment. Rau tib lub binder, yog tias tus nqi ntawm cov xim yog tib yam, qhov loj dua cov khoom, qhov ntau dua qhov viscosity, thiab vice versa. Qhov zoo dua cov xim dispersion, qhov me me ntawm viscosity ntawm tus number case, thiab vice versa, qhov ntau dua qhov viscosity ntawm tus number case.

(3) Kub hloov pauv. Thaum qhov kub thiab txias, qhov txheeb ze fluidity ntawm cov molecules nyob rau hauv tus number case nce thiab viscosity txo; Thaum qhov kub thiab txias, qhov cohesion ntawm tus number case molecules nce thiab viscosity nce.

Ink printing xovxwm manufacturers ntseeg hais tias thixotropy ntawm number case yog cov cuab yeej ntawm tus number case fluidity hloov nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam. Ntawm lub tshuab luam ntawv, vim qhov kev ua ntawm tus number case roller, qhov fluidity thiab ductility ntawm tus number case nce thaum lub sij hawm hloov mus, kom txog thaum lub zog sab nraud ploj tom qab hloov mus rau daim ntawv luam tawm, thiab nws cov fluidity thiab ductility txo, thiab tus number case hloov los ntawm nyias mus rau tuab, yog li ua kom qhov tseeb thiab meej ntawm embossing thiab dots. Thaum tus number case muaj thixotropy zoo, nws yog qhov tsim nyog rau kev sib hloov ntawm tus cwj mem thiab txhim kho qhov hloov pauv ntawm tus number case.
