Process description of solid wood paint products:

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.

E: all equipment and cutting tools:

⑦: PC-27 lower shaft high-speed milling machine ⑧: PC-23 upper shaft high-speed milling machine.

Pet-name ruby: LECO German cemented carbide tool Pet-name ruby: CNC machining center.

3. Grinding and painting:

A: After pasting the decorative panel, milling the edge-shaped panel, grinding the rough surface with Qurui SMA belt 180# on the VEIT sander, then grinding the rough surface of the edge-shaped surface with imported SZA sandpaper 180# and spraying the primer.

B: After the blank is polished, the veneer and edge surface are colored with German IDOPA brand paint primer, and the primer can be sprayed after the colorant is dried.

C: before spraying the primer, blow off the ash on the surface of the plate with high-pressure air, and then use Iwata brand spray gun imported from Japan and German IDOPA brand PU ultra-clear transparent primer (PE primer if fully enclosed) for back sealing. According to the requirements of different surface effects, it is necessary to spray the primer for 4-8 times. After each primer spraying, it is necessary to use the Swedish SZA brand 320# abrasive belt to polish on the VEIT brand broadband sander to ensure the smoothness of the plate surface.

D: after each priming process is completed, the plate is colored with IDOPA color essence according to different colors to achieve different surface color effects, and then the transparent topcoat with idopu (or PE) is used for 2-4 times. The Iwata brand spray gun with aperture of 1.5mm can ensure the smooth and delicate surface of the plate. The sprayed board can be assembled and packaged after 4 hours in the drying room.

C: equipment used:

①: Target 223 Italian-made twin-roll wide-band sander ②: Japanese Iwata brand spray gun.

③: Fully automatic painting assembly line.

4. Assembly and packaging

Answer: After the painted parts are fully inspected and qualified, the products are first assembled for the second time, and the assembled products are combined. The whole assembly product is assembled with imported hardware, wooden tenons and glue, while the parts of the folded product are only assembled with wooden tenons. Then each part is wrapped with pearl cotton for protection, and then the whole product is packed in a five-layer cowhide carton with foam corner protection and four edges protection. Finally, use the tape machine.
