Flexo, raws li lub npe qhia, yog flexographic luam ntawv phaj ua los ntawm cob thiab lwm yam ntaub ntawv. Nws yog lub tshuab luam ntawv tshuab luam ntawv. Tus nqi ntawm kev ua phaj yog qis dua li cov hlau luam ntawv phaj xws li intaglio tooj liab daim hlau. Txoj kev luam ntawv no tau npaj rau hauv nruab nrab ntawm lub xyoo pua xeem. Txawm li cas los xij, nyob rau lub sijhawm ntawd, kev txhawb nqa dej-raws li number case technology tsis tau tsim zoo heev, thiab cov kev cai rau kev tiv thaiv ib puag ncig tsis muaj kev txhawj xeeb thaum lub sijhawm ntawd, yog li kev luam ntawv ntawm cov khoom tsis nqus dej tsis tau txhawb nqa.

Txawm hais tias flexographic luam ntawv thiab gravure luam ntawv yog qhov zoo ib yam hauv cov txheej txheem, lawv yog ob qho tib si unwinding, winding, number case hloov, ziab, thiab lwm yam, tab sis tseem muaj qhov sib txawv loj hauv cov ntsiab lus ntawm ob. Yav dhau los, gravure thiab hnyav-raws li inks muaj cov teebmeem luam ntawv pom tseeb. Zoo dua li kev luam ntawv flexographic, tam sim no nrog kev txhim kho zoo ntawm cov dej-raws li inks, UV inks thiab lwm yam kev lag luam ib puag ncig tus phooj ywg thev naus laus zis, cov yam ntxwv ntawm flexographic luam ntawv tau pib tshwm sim, thiab lawv tsis qis dua rau gravure luam ntawv. Feem ntau, flexographic luam ntawv muaj cov yam ntxwv hauv qab no:

1. Tus nqi qis dua

Tus nqi ntawm kev ua phaj yog qis dua li ntawm gravure, tshwj xeeb tshaj yog thaum luam ntawv hauv cov khoom me me, qhov sib txawv loj heev.

2. Siv tus cwj mem tsawg dua

Lub flexographic luam ntawv txais yuav ib lub phaj flexographic, thiab tus number case yog hloov los ntawm anilox cov menyuam, thiab tus number case noj yog txo los ntawm ntau tshaj 20% piv nrog intaglio phaj.

3. Lub tshuab luam ntawv ceev ceev thiab kev ua haujlwm siab dua

Lub tshuab luam ntawv flexographic nrog cov kua dej zoo tshaj plaws tuaj yeem ncav cuag qhov siab ceev ntawm 400 meters ib feeb, thaum lub tshuab luam ntawv gravure feem ntau tsuas yog ncav cuag 150 meters.

4. Ntau tus phooj ywg ib puag ncig

Nyob rau hauv flexo luam ntawv, dej-raws li inks, UV inks thiab lwm yam ib puag ncig tus phooj ywg inks feem ntau yog siv, uas yog ntau tus phooj ywg ib puag ncig dua cov kuab tshuaj raws li inks siv nyob rau hauv gravure. Yuav luag tsis muaj VOCS emissions, thiab nws tuaj yeem ua zaub mov qib.

Feature ntawm gravure printing

1. Tus nqi siab ntawm kev ua phaj

Thaum ntxov, gravure daim hlau tau ua los ntawm kev siv tshuaj corrosion, tab sis cov nyhuv tsis zoo. Tam sim no laser daim hlau tuaj yeem siv tau, yog li qhov kev txiav txim siab yog siab dua, thiab cov ntawv luam ntawv ua los ntawm tooj liab thiab lwm yam hlau yog ruaj khov dua li cov phaj hloov tau yooj yim, tab sis tus nqi ntawm cov phaj ua kuj siab dua. Siab, ntau dua pib peev.

2. Kev luam ntawv zoo dua thiab sib xws

Cov hlau luam ntawv phaj zoo dua rau kev luam ntawv loj, thiab muaj qhov sib xws zoo dua. Nws raug cuam tshuam los ntawm thermal expansion thiab contraction thiab yog me me

3. Kev siv tus number case loj thiab cov nqi ntau lawm

Nyob rau hauv cov nqe lus ntawm tus number case hloov, gravure printing siv ntau tus number case, uas zoo li nce nqi ntau lawm.
