Knowladge of Melamine plywood

What is melamine plywood?

Melamine faced boards, whose base material is particle board and MDF, are made by bonding the base material and the surface. There are mainly two types of surface veneers: domestic and imported. , Waterproof soaking treatment, the use effect is similar to that of composite wood flooring.


Melamine board, referred to as melamine board, the full name is melamine impregnated film paper veneer wood-based board. It is to soak paper with different colors or textures in melamine resin adhesive, then dry to a certain degree of curing, and pave it on particleboard, moisture-proof board, medium density fiberboard, plywood, blockboard, multi-layer board or other Hardboard surface, heat-pressed decorative panels. In the production process, it is generally composed of several layers of paper, and the number depends on the application. Melamine board is not a new product, and the fancy name does not mean that the product is fresh.

Soak the decorative paper in a melamine solution, and then press it on with a hot press. Therefore, the moisture-proof board for furniture is generally called melamine moisture-proof board. Melamine-formaldehyde resin is a solution with very low formaldehyde content, which is environmentally friendly. This way it will not cause secondary pollution, but will reduce the release of the substrate inside. This approach has been recognized by everyone, and most of them are doing this. However, the surface treatment is also divided into good and bad, because the price of melamine-formaldehyde resin solution is almost 10 times that of other glues, and many people mix urea-formaldehyde glue into the solution, which is not environmentally friendly, so the board is also divided into full trimeric and Semi-polyboard, this is not easy for non-professionals to recognize, it mainly depends on whether the surface is transparent.

Composition of melamine paper for the melamine plywood:

“Melamine” is one of the resin adhesives used to make this kind of board. Papers with different colors or textures are soaked in resin, dried to a certain degree of curing, and paved on the surface of particleboard, medium density fiberboard or hard fiberboard. , the decorative board made by hot pressing, the standard name is melamine impregnated film paper veneer wood-based panel, saying that its melamine board is actually a part of its veneer composition. Generally, it is composed of surface paper, decorative paper, covering paper and bottom paper.

①Surface paper is placed on the top layer of the decorative board to protect the decorative paper, making the surface of the board highly transparent after heating and pressing, hard and wear-resistant. This kind of paper requires good water absorption, white and clean, and transparent after dipping .

② Decorative paper, that is, wood grain paper, is an important part of the decorative board. It has a background color or no background color. The decorative paper printed into various patterns is placed under the surface paper and mainly plays a decorative role. This layer requires The paper has good hiding power, impregnation and printing properties.

③ Covering paper, also called titanium white paper, is usually placed under the decorative paper when manufacturing light-colored decorative boards to prevent the underlying phenolic resin from penetrating the surface. Its main function is to cover the color spots on the surface of the substrate. Therefore, good coverage is required. The above three kinds of paper are impregnated with melamine resin respectively.

④The base paper is the base material of the decorative board, which plays a role in the mechanical properties of the board. It is made by impregnating phenolic resin glue and drying. The number of layers can be determined according to the application or the thickness of the decorative board during production. When choosing this kind of panel furniture, in addition to satisfactory color and texture, you can also distinguish the appearance quality from several aspects. Whether there are stains, scratches, indentations, pores, whether the color and luster are uniform, whether there are bubbles, whether there are local paper tears or defects.
