Industry development
In recent years, the demand for the eco-board industry has gradually increased, and the price of ecological boards has also diversified. According to market research, in 2003, China's use of ecological board as a furniture production material has a market share of only 36%. By 2014, this share rose to over 86%. It has become the material of choice for furniture, flooring and upholstery. This demonstrates the huge market demand for eco-board products. In the next few years, the price of China's ecological board will continue to diversify and develop, and the overall price is on the rise. The price of eco-boards on the market is high or low, and the price of eco-boards depends on the raw materials used (such as cores, facing papers, adhesives, rubber sheets), and also with the veneering technology used. Big relationship. As the top ten brand of China's eco-board, Huaxiang Plate, we share the veneer technology of the eco-board.
What is an ecological board?
Eco-board, also known as paint-free board, is used to soak melamine paper with different colors or textures in the resin, dry it to a certain degree of curing, and lay it on blockboard, plywood, particleboard, MDF or A surface of a hard fiberboard or the like, which is hot-pressed, is a melamine-impregnated film-finished wood-based panel.
Generalized and narrow sense
1. In a broad sense, the ecological board is equivalent to the melamine veneer. The full name is melamine impregnated paper-finished wood-based panel. It refers to the paper with different colors or textures soaked in the eco-plate resin adhesive, and then dried to a certain curing. To the extent, it is laid on the surface of particleboard, moisture-proof board, medium density fiberboard, plywood, blockboard or other hardboard, and hot-pressed decorative board.
2. The ecological board in the narrow sense refers only to the melamine veneer used in the middle of the substrate for multi-layer solid wood (plywood), blockboard (such as Malacca, Chinese fir, paulownia, poplar, etc.). Mainly used in furniture, cabinet wardrobes, bathroom cabinets and other fields.

The difference between direct and repost
1. Directly attaching the process ecological board: firstly, the eco-plate core and the rubber board are pasted into a blank by high-temperature hot pressing after low-temperature cold pressing, and then a layer of veneer is attached to the two sides of the blank by high-temperature hot pressing to form a substrate, and finally The eco-curtain facing paper is directly attached to the substrate through the high-temperature hot pressing paste to synthesize the ecological board. The direct sticking requires high quality of the core and the flatness of the board surface, and precise control technology is needed in terms of pressure, temperature and pressing time.
Re-applying process ecological board: firstly, the eco-curtain facing paper and the rubber sheet are pasted together, and then the composite board is attached to the core after low-temperature cold pressing, and the board flatness and worker technical requirements are not high, and the board surface is easy. Wave pattern is produced (the slope of the board is inclined at 45°, and the dark lines on the board surface will affect the appearance of the board).
Second, the direct paste process ecological board: the use of high temperature and high pressure, effective evaporation of the moisture generated in the process of the ecological board bonding process, to ensure that the water content is moderate, late is not easy to open the glue, cracking, deformation, longer service life.
Re-applied process ecological board: low-temperature cold-pressed veneer, moisture retained in the solid wood skin between the ecological board and the core of the board. As the temperature difference changes, it is prone to cracking of the ecological board, deformation of the board, and even the opening of the board. Separation and other phenomena that affect the service life of furniture.
