Cov teeb meem tshwm sim thiab lawv cov kev daws teeb meem hauv cov txheej txheem luam ntawv siv intaglio dej-raws li number case suav nrog

1. Clogging

Nqe lus piav qhia: Clogging, tshwm sim los ntawm tsis zoo redispersibility ntawm dej-raws li number case, tuaj yeem ua rau luam tawm cov teeb meem zoo xws li cov pinholes, cov khoom ploj hauv cov ntawv me me, tsis sib xws ntawm tus number case, thiab substrate show-dhau thaum tuav tsis raug.

Kev kho mob:

• Rau kev txhaws vim yog kev kaw tsis tu ncua, cov cuab yeej tshwj xeeb thiab cov tshuaj ntxuav yuav tsum tau siv; Cov mob hnyav tuaj yeem xav tau tshem tawm cov phaj thiab ntxuav nrog cov kuab tshuaj organic xws li ethyl acetate. Ib qho kev pom zoo yog ua kom lub phaj tig thaum lub sijhawm poob.
• Kev ziab sai sai tuaj yeem txo tau los ntawm kev ntxiv 3-5% retarder kom qeeb tus number case curing thiab kho diluent ratios (feem ntau cawv-rau-dej 1: 1 rau 4: 1), thaum ceev faj tiv thaiv cov dej ntau dhau uas tuaj yeem tsim npuas thiab tsis tiav ziab.
• High viscosity number case yuav tsum tau thinned kom tsim nyog, ntsuas qhov nrawm thiab qib siab, kom tsis txhob muaj npuas lossis degradation ntawm cov duab cov ntsiab lus los ntawm cov viscosity tsawg dhau.
• Qhov tob ntawm tes yuav tsum tau ua kom tob, tab sis kev saib xyuas yuav tsum tau ua raws li cov hlwb sib sib zog nqus tuaj yeem ua rau cov cim thiab qhov muag plooj zoo.

2. Phaj Dirt Dragging

Nqe lus piav qhia: Thaum lub sij hawm dej-raws li number case luam ntawv, tshwj xeeb tshaj yog nyob ib ncig ntawm barcodes los yog tsaus nti duab, residue number case vim tsis txaus scraping cov ntaub ntawv av streaks, ib qho teeb meem txuas mus rau lub qis lubrication ntawm cov dej-raws li inks piv rau cov kuab tshuaj.

Cov tswv yim daws teeb meem: Ink manufacturers yuav tsum muab cov additives los txhim kho lubrication; cov tshuab luam ntawv yuav tsum tau kho cov kaum sab xis thiab siab, nrog cov hniav luv luv ua pov thawj ntau dua.

3. Qhuav tsis txaus

Nqe lus piav qhia: Dej-raws li number case dries qeeb dua li cov kuab tshuaj raws li cov kuab tshuaj, thiab tsis txaus ziab ua rau cov menyuam adhesion.

Kev ntsuas qhov ntsuas: Ua kom qhov ziab kom qhuav los ntawm 10-20 ° C, ua kom qhov cua nkag, thiab, yog tias ua tau, txuas rau daim ntawv mus ncig yuav pab tau. Kev sib koom tes nrog cov neeg muab tus cwj mem rau kev hloov kho cov qauv los txhim kho cov khoom kom qhuav kuj tseem ceeb heev.
