Plywood veneer is a material that is used in daily decoration or construction, so it will be used more in the decoration industry. However，what is the specific plywood veneer production line? This article will introduce you in detail.

What is Plywood Veneer Production Line
Plywood veneer is a thin veneer of solid wood precisely sliced into a thin veneer with a thickness of 0.2 mm or more. Using plywood as a base material, it is a decorative sheet with a single-sided decorative effect produced by the plywood veneer production line. Its surface sheet is a precious wood species with natural texture, stable and reliable performance, and is a commonly used decoration material for home decoration nowadays.
The plywood veneer production line is a series of processes for producing glued veneer. Firstly, the ordinary cheap logs are cut to length and softened. This is the first step of the plywood veneer production line. After the wood section has been fully softened, sawing and cutting are carried out. When cutting, the saw is cut according to the requirements of straight grain or mountain pattern. Then, the wood is sliced into thin wood according to different thickness requirements by a planer, and manually stacked, and then the rough edge of the thin wood is cut off with a cutting machine to form thin wood with different widths. Next, in the plywood veneer production line, the thin wood is clipped with a special tool in the stripping pool for stripping until the original wood color is completely removed. Then thoroughly filter out the chemical solution on the thin wood with clean water, and then put it in the dyeing tank to heat and dye. At this time, the most important thing is to master the ratio and temperature of the pigment. Generally, the color is matched according to the target color through the computer, the color number ratio and the mass ratio of each clock are analyzed, and then weigh the material accurately in proportion.
After that, the next step of the plywood veneer production line will be carried out. The dyed veneer needs to be dried 70% and then used for veneer. For veneer substrates, it is also necessary to enter the plywood veneer production line at this time. The defects that affect the flatness of the finished product must be processed first, and then sanded. After that, according to the different luster of the thin wood, the corresponding coloring concealing agent is selected for color addition and drying to unify the color of the substrate and the thin wood and keep it dry. Then, in the plywood veneer production line, you need to prepare glue. Manually glue the veneer on the substrate in order to form the veneer blank board. The veneer blank board needs to be collected and stacked manually. Go to the cold press to cold press to speed up the initial bonding. Generally, it can be sent out after 1-2 hours to cut off the thin wood hair. After that, it is inspected, and curing and sanding are considered complete.
It can be seen that the plywood veneer production line is very complicated, and it requires concentrated effort to study and practice to be able to operate proficiently. If you want to work in this area or introduce technology, you can learn from professional technicians.
