Yeej twg yuav tshwm sim rau qhov tsim nyog ntawm duv lamination hlau?

Thermal lamination film, tam sim noj, yog ib lub composite film uas muaj EVA adhesive tau coating ua ntej rau hauv ib lub base film. Thaum siv lamination, peb tsuas yog sauv qhov EVA los ntawm kev siv hot press, thiab tom qab ntawd lub film yuav raug laminated rau hauv cov ntawv sau lossis phiev.

Cov feem cuam txwm twg tuaj yeem tshwm tau rau qhov kualitee ntawm thermal lamination film thaum tsim khoom?

Corona Value

Qhov corona tsawg dua feem ntau yuav tshwm sim qhov adhesion tsau nyooj hauv qab thaum lamination. Tom qab ntawd, qhov corona ntau dua feem ntau tuaj yeem tshwm sim sedimentation hauv lub pre-coated film. Yog li no, zoo tshaj plig kom saib xyuas qhov power output ntawm corona hauv qab thaum tsim khoom.

Tsheej ntsha, peb cov corona value yuav tsum muaj ≥38 dyne.

EVA Layer Thickness Uniformity

EVA thickness tsis muaj zog tuaj yeem tshwm sim cov bubbles thiab cov chaw tsis muaj zog hauv qab lossis tom qab film laminating.

Kom txo qhov adhesive layer thickness tsis muaj zog, EKO tau muab ib lub thickness gauge los ntawm Xylias kom saib xyuas qhov film uniformity nyob hauv qab coating nyob ze, kom paub meej tias khoom muaj kualitee.

Cov Khoom Siv Zoo Zoo

Lub khw kev cawm muaj txiaj ntsig zoo tseem yog qhov chaw tsim nyog rau kev siv cov khw muaj txiaj ntsig zoo. Nyob hauv cheeb koom ntawm cov khw, EKO thiaj li tau xav tau siv cov ntaub ntawv pheej hmab zoo tshaj plaws thiab cov EVA khw ntau yam los ntawm sab nraud tuaj los kom paub meej tias tus khw muaj txiaj ntsig zoo thiab txheej xeem.
