Solid wood panels use different structural forms, the narrow solid wood panels combined into the required width of the board, such as solid wood table and solid wood chair board, different splicing methods bring different viewing effects.
In addition to limiting the width of the narrow solid wood panels, the panel structure is also used, the material characteristics of the tree species in the same panel component should be the same or similar, and the moisture content deviation of the adjacent solid wood panels should not exceed 1%. The structure of solid wood panels is diverse, so in actual production, the appropriate panel form should be selected according to different purposes.
The proportion and use of plywood
1. The glue mixing ratio is: main agent: curing agent = 100:15 (weight ratio), the best use effect is 3-5 minutes after full mixing, the glue temperature should be controlled between 10℃-25℃.
2. Effective use time after glue ratio. When the room temperature is 20 ° C, a certain amount of glue must be used within 40 minutes each time, and in the summer, it is required to be used up within 30 minutes.
3. The basic amount of glue is 250-300g /㎡, and continuous granular rubber particles need to be extruded on the end face and surface of the panel. Otherwise, it may be due to the insufficient amount of glue, opening time is too long, resulting in poor wood processing accuracy, insufficient unit pressure, etc., it is recommended to apply double glue at the end of the board.
Assembling process requirements
1. When the room temperature of the panel is between 15 ° C and 25 ° C, close and press the panel within 10 minutes after gluing. If the opening time is too long, the adhesive layer will more easily form a film, which will affect the penetration bond, form a false bond and lead to the rupture of the piece.
2. The pressure pressure of the board: cork is 8-12kg/cm2, hardwood is 12-15kg/cm2. As the thickness of the plate increases, the pressure increases correspondingly, and the pressure holding time is correspondingly extended.
3. The two ends of the board must be firm. The fixture must be stuck at the end of the circuit board, otherwise it will be more prone to end cracking phenomenon, it is recommended that the distance between the two focal points does not exceed 300mm.
