1. Veneer veneer:
A: Imported E 1 grade high-density board, sawed into blanks with cutting board, and sawed with Italian heavy-duty board machine.
B: Use imported AB two-component adhesive (this adhesive is characterized by natural water resistance, heat resistance and stronger strength than wood flour and white latex). Seal dry solid wood with different thickness (Indonesian white wood with water content below 10%) according to the plate condition. Then, the solid wood is planed with planer and press planer, and finally, the solid wood edge-sealed plate is sanded with Italian VIET brand broadband sander with equal thickness. To ensure the thickness of the plate and the close combination of veneer and plate.
C: Cut the bark of 0.6mm thick black walnut or cherry imported from the United States on a shearing machine (Italian Casati brand). Splicing veneer patterns with veneer stapler (KUPER brand, Germany), and then using hot press (BAGO brand, Germany) to bond veneers to both sides of the board at the high temperature of 1 10 and the high pressure of 5Kg/cm2. This adhesive has high bonding strength, is resistant to natural water, and does not contain formaldehyde (hot pressing process takes 2 minutes).
D: This process is called "sealing solid wood first, then pasting thin wood". Its advantage lies in that the veneer of the processed board and the edge of the solid wood are integrated, and there will be no gaps in the board surface, which is natural and beautiful.
