"Melamine" is one of the resin adhesives used in the manufacture of such sheets. Papers with different colors or textures are soaked in the resin, dried to a certain degree of solidification, and laid on the surface of particleboard, medium density fiberboard or hardboard. The hot-pressed decorative board, the name of the specification is a melamine impregnated film-finished wood-based panel, said its melamine board is actually part of its finishing composition.
It is generally composed of surface paper, decorative paper, cover paper and bottom paper.
1 The surface paper is placed on the top layer of the decorative board to protect the decorative paper. The surface of the board after heating and pressing is highly transparent, and the surface of the board is hard and wear-resistant. This paper requires good water absorption, clean white, transparent after dipping. .
2 Decorative paper, that is, wood grain paper, is an important part of the decorative board. It has a base color or a baseless color. The decorative paper printed in various patterns is placed under the surface paper, mainly for decorative purposes. Paper has good hiding power, impregnation and printing properties.
3 Covering paper, also known as titanium white paper, is usually placed under the decorative paper when manufacturing the light decorative panel to prevent the underlying phenolic resin from penetrating the surface, and its main function is to cover the color spots on the surface of the substrate. Therefore, good coverage is required. The above three types of paper are respectively impregnated with melamine resin.
4 The bottom paper is the base material of the decorative board. It plays a mechanical role on the board. It is made by dipping the phenolic resin glue. It can be determined according to the application or the thickness of the decorative board.
The melamine board makes the furniture look strong. The paper with color or imitation wood grain is fragile. The film formed by immersing in the transparent resin of melamine board is much harder. The film paper is hot pressed with the substrate. After the product has good performance, the furniture made with it does not need to be painted, the surface naturally forms a protective film, wear-resistant, scratch-resistant, acid and alkali resistant, hot and pollution resistant. In the selection of such panel furniture, in addition to the satisfaction of color and texture, the appearance quality can be distinguished from several aspects. Whether there are stains, scratches, indentations, voids, whether the color gloss is uniform, whether there is bubbling, whether there is partial paper tear or defect.
The full name of the melamine board is a melamine impregnated paper-finished wood-based panel. The paper with different colors or textures is immersed in a melamine resin adhesive, and then dried to a certain degree of solidification, and laid on a particle board, a medium density fiberboard or The surface of the hard fiberboard is formed by hot pressing.
