In the field of modern building decoration and furniture manufacturing, wall panel as an important decorative material, its production process and equipment selection directly affect product quality and production efficiency. At present, PUR flat laminating machine has become the mainstream equipment for wallboard production, with its excellent performance and efficient production capacity, occupies an important position in the industry. This article will comprehensively analyze the application of PUR flat laminating machine in the production of wallboard, advantages and purchase points.
First, the PUR machine: the core equipment for wallboard production
1. Equipment definition and working principle
PUR flat laminating machine is a kind of professional laminating equipment using polyurethane reactive hot melt adhesive (PUR adhesive),
through the precise temperature control and pressure system, all kinds of finishing materials and substrates firmly bonded.
Its working principle mainly includes:
Glue heating system: heating the solid PUR glue to a molten state (about 120-150°C)
Precise coating system: uniform glue application by roller coating or spraying
2. Core advantageous features
PUR flat laminating machine has significant advantages over traditional equipment:
Strong adhesive force: PUR adhesive cured to form an irreversib
le crosslinking structure, peel strength of up to 8-12N/mm.
Efficient production: from sizing to press-fit completion in 30-90 seconds, 5-10 times faster than the manual process.
Environmental protection and safety: solvent-free, very low VOC emissions, in line with the E0 environmental standards.
Wide adaptability: can handle PVC film, decorative paper, PET and other finishing materials.
Second, the application of PUR flat laminating machine in the production of wall panels
1. Applicable wallboard types
PUR flat laminating machine is widely used in the following wallboard production:
PVC laminated wall panels: medical, education and other places special wall panels
PET veneer panels: decorative wall panels for cabinets and closets.
Wood grain paper printed wall panels: decorative wall panels imitating the effect of solid wood
Fireproof board: special fireproof decorative wall panels for public places
2. Typical production process
Substrate pretreatment: sanding and dust removal (surface roughness Ra ≤ 3.2μm)
PUR adhesive coating: coating amount 80-120g/m².
Finishing material lamination: temperature 100±5℃, line pressure 30-50N/cm
Split board trimming: manual cutting of membrane material
