Embodiment 1
[0028] Example 1. Sawing straight-edged boards
[0029] 1. Milling and trimming of the edge of the base material: the sliding table saw cuts the rice straw board, and the saw blade rotates at 4000r / min. Saw and cut into 250*200*32mm straight-edged boards. After milling the edge of the rice straw board, clean the edge with 180# sandpaper to remove dander.
[0030] 2. Use putty to inlay rice straw board: putty made of CaCO 3 , water, white latex, carboxymethyl cellulose, etc. (200:100:20:3), using white latex with a high solid content (50%), after the edge of the rice straw board is embedded, dry at room temperature 4h, then sand the surface with 180# sandpaper to remove the excess putty on the surface; the roughness after sanding is 4.09um.
[0031] 3. Polyurethane sealing primer: spray polyurethane sealing primer on the rice straw board, the mass ratio of polyurethane sealing primer is PU primer: PU curing agent: PU thinner = 1:0.5:0.5, viscosity 17s, spray 1 Cross (coatin...
Embodiment 2
[0040] Embodiment 2. Milling machine milling plate (convex type)
[0041] 1. Milling and trimming of the edge of the base material: the sliding table saw cuts the rice straw board, and the saw blade rotates at 10000r / min. Saw and cut into 250*200*32mm straight-edged boards. After milling the edge of the rice straw board, clean the edge with 180# sandpaper to remove dander.
[0042] 2. Use putty to inlay rice straw board: putty made of CaCO 3, water, white latex, carboxymethyl cellulose, etc. (200:100:20:3), using white latex with a high solid content (50%), after the edge of the rice straw board is embedded, dry at room temperature 4h, then sand the surface with 180# sandpaper to sand off the excess putty on the surface; the roughness after sanding is about 4.4 um.
[0043] 3. Polyurethane sealing primer: spray polyurethane sealing primer on the rice straw board, the mass ratio of polyurethane sealing primer is PU primer: PU curing agent: PU thinner = 1:0.5:0.5, viscosity 1...
Embodiment 3
[0052] Example 3. Milling machine milling plate (concave type)
[0053] 1. Milling and trimming of the edge of the base material: the sliding table saw cuts the rice straw board, and the saw blade rotates at 10000r / min. Saw and cut into 250*200*32mm straight-edged boards. After milling the edge of the rice straw board, clean the edge with 180# sandpaper to remove dander.
[0054] 2. Use putty to inlay rice straw board: putty made of CaCO 3 , water, white latex, carboxymethyl cellulose, etc. (200:100:20:3), using white latex with a high solid content (50%), after the edge of the rice straw board is embedded, dry at room temperature 4h, then sand the surface with 180# sandpaper to remove the excess putty on the surface; the roughness after sanding is about 4.2um.
[0055] 3. Polyurethane sealing primer: spray polyurethane sealing primer on the rice straw board, the mass ratio of polyurethane sealing primer is PU primer: PU curing agent: PU thinner = 1:0.5:0.5, viscosity 17s, ...
