Embodiment approach
[0060] As an embodiment of the present invention, the production method of high-density composite fiberboard comprises the following steps:
[0061] S1: Heat the core board with steam, stop heating when the surface temperature of the core board is 20-30 degrees Celsius, and stick the panel to the two sides of the core board respectively to obtain a semi-finished product. When the surface temperature of the core board is 20-30 degrees Celsius, you can Ensure the highest bonding strength of the core board, while the core board itself is a paste;
[0062] S2: Sprinkle a layer of evenly distributed plant ash on the surface of the semi-finished peripheral core plate obtained in S1, and press it through a cold press. When the core plate height is 1-2 cm during the pressing process, stop extrusion Pressing, through the cold press to carry out the pressing process, can effectively increase the density of the core board and the panel, and at the same time improve the adhesion strength ...
