Decorative wood veneer manufacturer: manufacturing process of sliced veneer
Usually, natural veneer is processed through planing. Decorative wood veneer manufacturer: The process flow is as follows
Log → Cutting → Softening (steaming or boiling) → Planing → Drying (or not drying) → Cutting → Packaging Inspection → Warehousing
The decorative veneer manufacturer will only introduce three important steps below:
Decorative wood veneer manufacturer: cutting
After the log enters the factory, it should be cut into wooden segments according to the required length. Then, when cutting the wood, the sawing plan should be selected based on the diameter of the log, the wood grain, and the fixing method of the wood on the planer. This way, the width of the cut veneer should not be less than the relevant requirements.
A reasonable solution not only has a high yield, but also produces more cut diameter veneers and fewer cut string veneers, making the product highly decorative. Different sawing schemes should be used for logs of different diameter grades. The thick and solid lines in the figure are saw lines, and the arrow direction is the cutting direction of the planer:
In actual production, logs with a diameter less than 400mm usually use sawing scheme B, while logs with a diameter of 400-800mm mostly use sawing schemes D and E Using these sawing schemes to produce veneer has high yield, good veneer quality, and high planer efficiency.
Decorative wood veneer manufacturer: steaming and boiling
After wood steaming (i.e. hydrothermal treatment), the plasticity of the wood increases. The effective method to improve the plasticity of wood is to simultaneously adjust the temperature and moisture content, that is, to simultaneously increase the temperature and moisture content of the wood. This is why saturated steam or hot water is commonly used in actual production for cooking and hydrothermal treatment of wood.
Firstly, when placing the wooden cube into the cooking pool, it should be done according to the specifications of the tree species and the wooden cube; The water temperature should be kept at room temperature and slowly increased to avoid cracking of the wood due to thermal stress. When the temperature rises to above 40 ℃, the heating rate should be slowed down; Excessive cooking can also reduce the quality of the veneer; Regularly remove resin, bark, and sediment from the cooking pool, and change water frequently to reduce wood pollution; The cooked wood should be placed in a warm water tank in front of the planer in a timely manner, and the temperature should be maintained within the range of 40-50 ℃ (depending on the tree species and veneer thickness).
Decorative wood veneer manufacturer: dry
After drying, the moisture content is generally 8% to 12%. The veneer drying equipment includes a continuous drum dryer, a belt dryer, and an intermittent drying chamber. The drying room is an old-fashioned drying equipment that is very uneconomical, but the drying quality is better. The drum dryer is a widely used type. Thin wood should use a belt dryer, especially for thin wood with a thickness of less than 0.4 millimeters.
