What are the characteristics of melamine board?
It is often said that in order to make the best sheet, we must keep up with the lifeblood of the times. Modern boards include eco-boards, melamine boards, paint-free boards, flame retardant boards and so on. Melamine boards are popular because of their high sales volume and obvious characteristics. Melamine board is fully known as melamine impregnated paper veneer wood-based panels. Paper with different colors or textures is soaked in melamine resin adhesives, then dried to a certain degree of curing, and laid on the surface of particleboard, medium density fiberboard or hard fiberboard, after hot pressing. Melamine board has the advantages of flat surface, easy deformation due to the same expansion coefficient on both sides of the board, bright color, wear-resistant surface, corrosion resistance, and economic price. Melamine veneer door panels produced in China are represented by dew river panels, and all indicators have reached international standards.
Melamine board shortcomings: low grade, easy edge collapsing, glue traces are more obvious, less color, can not Gong flower can only be straight edge sealing.
Melamine board is generally composed of surface paper, decorative paper, covering paper and bottom paper.
Surface paper is placed on the top of decorative board to protect the decorative paper. It makes the surface of the board highly transparent after heating and pressing. The board surface is hard and wear-resistant. This paper requires good water absorption, clean and transparent after dipping. (2) Decorative paper, i.e. wood-grain paper, is an important part of decorative board. It has background color or no background color. The decorative paper printed into various patterns is placed under the surface paper, which mainly plays an decorative role. This layer requires that the paper has good covering power, impregnation and printing performance. (3) Covering paper, also known as titanium white paper, is usually placed under decorative paper when making light-colored decorative board to prevent 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 were impregnated with melamine resin. (4) Base paper is the base material of decorative board. It plays a role in mechanical properties of board. It is made by dipping phenolic resin and drying. In production, several layers can be determined according to the use or thickness of decorative board.
