Laminating yog cov txheej txheem los ntawm ob lossis ntau lub hnab ntim khoom yooj yim tau koom ua ke siv abonding agent rau lamination.
Cov substrates ua cov webs yuav muaj cov yeeb yaj kiab, ntawv, lossis aluminium foils. Hauv cov ntsiab lus dav dav a lamination adhesive yog siv rau qhov tsawg absorbent substrate web, tom qab uas lub web thib ob yog nias tawm tsam nws los tsim ib tug duplex, los yogob txheej laminate.
Laminating machinery thiab laminating hom: laminating machinery tuaj yeem faib raws li hom kev sib koom ua ke siv los tsim cov laminates. Cov hom no yog:
- Cov lamination ntub dej: qhov twg tus neeg sawv cev sib txuas tseem nyob hauv lub xeev ua kua thaum lub webs tau koom ua ke. Nws yog feem ntau siv los tsim cov ntawv-aluminium foil laminate uas yog siv dav hauv ntim khoom.
- Qhuav lamination:qhov twg tus neeg sawv cev sib txuas, yaj rau hauv cov kua (dej lossis cov kuab tshuaj), yog siv rau ib qho ntawm cov webs, ua ntej evaporated hauv qhov cub kom qhuav. Cov nplaum nplaum lub vev xaib yog laminated rau lwm qhov nyob rau hauv lub zog siab thiab siv cov rhuab chais, uas txhim kho lub zog ntawm lub laminate.
- Wax lamination: qhov twg tus neeg sawv cev sib txuas yog siv quav ciab lossis kub yaj thiab siv rau hauv lub xeev molten mus rau ib qho ntawm ob lub substrates. Cov txheej txheem no tso cai rau kev tsim cov ntawv-daim ntawv lossis ntawv-aluminium foil laminates uas tau siv dav rau kev ntim khoom ntawm biscuits thiab bakery khoom.
- Solventless lamination: qhov twg cov nplaum siv tsis muaj cov kuab tshuaj. Solventless adhesive feem ntau qhia txog ib hom ntawm cov nplaum uas tsim los ntawm ob lub ntsiab lus sib cuam tshuam nrog ib leeg thiab yog li tsis tas yuav ziab.
