Key Features:High-Speed Design: Engineered for rapid production cycles, significantly increasing output rates without compromising quality.
Low Resin Pickup: Advanced technology ensures minimal resin uptake, reducing costs and improving the environmental footprint.
Longevity: Built with high-quality materials and components, this line offers extended operational life and reduced maintenance needs.
Versatile Application: Perfectly suited for the production of high-pressure laminate (HPL) surfaces and core layers, providing the essential properties needed for durability and aesthetics in final products.
One Step Impregnation Line for Phenolic Kraft Paper, mostly it is 4 ft line, suitable for 4 x 8 ft and 1.3 x 2.8 Meter hpl finishing. In some case, the client also impregnate 8-foot-wide paper and cut 8-foot x 4-foot in size to achieve high efficiency.
In compact HPL production, use urea and formaldehyde as raw materials after many condensation reactions characterized of the growth of water-based resins: low shrinkage tendency; low transparency; chemical resistance; low surface deformation tendency. The white, light-color, plain-color woodgrained paper is pressed by short-cycle laminating hot press all impregnation process with two segments. In the process, the paper is dipped in the firetight rubber tank with a mixture of urea formaldehyde or urea and melamine gum, which is then coated in a second layer of pure melamine resin.
Especially in the production of light-colored paper, the opaque components of the urethral gel will enhance the covering power of the impregnated paper in the heat pressure.
The first section USES urea glue for impregnating paper, which can reduce the tension between the surface of the plate and the surface and reduce the tension between the surface and the pressure surface.
