Dab tsi yog qhov sib txawv ntawm minetpress thiab flexographic luam ntawv?

Letterpress luam tawm thiab flexographic luam ntawv tau rau tib kab ntawv me me, muaj ntau qhov sib txawv ntawm cov qauv siv, muaj cov yam ntxwv cuam tshuam thiab cov txheej txheem cuam tshuam. Lawv tuaj yeem sib txawv los ntawm tsib yam nram qab no:

Qhov sib txawv hauv phaj phaj thiab Hardness
LetterPress luam ntawv siv ib lub hnab ntim khoom tawv tawv nrog tsawg dua 1 hli (harpencees ntawm 90 dogrees ntawm 90M (nyuaj ntawm qhov siab tseem ceeb, uas yog qhov tsim nyog rau zoo dot luam ntawv.
Flexographic Printing siv cov ntaub so muag muag lub phaj nrog ib tuab ntawm 1 {{{}} 5 hli (hardness ntawm 30-70 degrees). Elasticity ntawm cov phaj tuaj yeem nqus tau luam ntawv luam ntawv siab hloov pauv thiab yog qhov tsim nyog rau cov tsis-ntiaj teb substrates.
Kev Kawm Txuj Ci Kev Lag Luam Kev Lag Luam
Daim ntawv sau luam ntawv tso siab rau kev ua si ntev ntev txoj kev sib tw ua ke ntawm tus neeg nyob hauv tus tub rog, thiab cov hlua khi. Tus Ink hloov tau tiav los ntawm ntau cov menyuam muaj kuab, uas yog nquag mus rau hauv lub ntim ntim hloov pauv.
Flexographic Printing siv cov kab hauv luv luv, uas yog qha rau cov menyuam mos kom tsawg. Tus nqi ntawm tus pas ntsuas hauv qhov chaw raug tswj tau yog tswj tau kom raug yog los ntawm lub xov tooj ntawm tes (feem ntau 20-40μm), thiab qhov kev ruaj khov ntawm cov number case yog txhim kho los ntawm ntau tshaj 30%.
Kev sib piv ntawm cov khoom siv lub cev ntawm inks
Nyem number cask yog qhov siab - viscosity paste (viscosity 50-200poom 50-200poom 50-200PAs), uas yuav tsum muaj zog shear zog los ua kom tiav kev hloov pauv thiab ua kom qeeb.
Flexo number case yog qhov qis - viscosity kua (viscosity 10 {2} {{2} {{2} lub taub hau ntev tuaj yeem ncav 2-3 zaug ntawm cov number case.
Qhov sib txawv hauv kev luam ntawv siab thiab cov nyhuv
Lub siab ntawm nyem cov luam ntawv feem ntau yog 0.15-0.3MPA, uas tuaj yeem yooj yim ua rau muaj kev deformation, thiab tus nqi ntawm Dot tuaj yeem ncav cuag 15% -20%.
Flexo lub tshuab luam ntawv siab yog tswj hwm ntawm 0.05 - 0.15mpa, thiab cov ntawv luam tawm dot tsim nyog rau high-precision video luam ntawm 70-150 kab / nti.
Kev sib piv ntawm cov txheej txheem kev siv
Cov kua mem kua txheej thickness ntawm nyem cov ntawv luam tawm hauv cov luam ntawv tuaj yeem ncav cuag 3-5μm, nrog kev nkag siab siab, tab sis muaj kev nkag siab ntawm qib ntawm qib kev hloov pauv.
Flexographic Printing tuaj yeem ua tiav 0.8-1.5μm nyias nums kua member, uas muaj zog rau kev luam tawm kev luam tawm cov khoom lag luam khoom noj.
