The Details That Must Be Paid Attention To In Wood Veneer Processing That Affect Quality

 

1. Cut the wood veneer raw material. Not only should attention be paid during the production process, but strict screening should be carried out at the source of the wood. The quality of wood directly determines the quality of the wood veneer. The bending, knot, and decay of raw materials are not allowed in the production of wood veneer, especially when combined with decayed raw materials. Therefore, strict selection is necessary when purchasing wood to ensure the quality of the wood veneer.

 

2. Preservation of wood. Because the extraction of logs is sometimes limited, a full year of production wood is prepared at a certain time of the year. Therefore, the preservation of wood veneer cutting raw materials before production is also very important. If not properly preserved, resulting in wood drying or quality change, they will become waste materials. Raw materials need to be watered 24 hours a day to maintain the moisture content of the wood, in order to ensure that the color of the produced wood bark does not change. However, it is also important to note that they should not be stored in the log yard for too long, resulting in soaking and dead or mottled wood bark.

 

3. Sawing and steaming of logs. The quality of the sawn logs directly determines the yield of the wood veneer and the changes in the texture of the veneer. Therefore, when sawing logs, attention should be paid to the defect changes and standards of the logs. Cooking plays an extraordinary role in the quality of wood veneer, both in terms of color and layout quality. Moreover, log cooking has a significant impact on the smooth cutting of wood veneer. The temperature and time of cooking should be strictly controlled, and heating, insulation, and cooling should strictly follow operating standards.

 

4. Quality assurance during the production process. Ensuring the quality of wood veneer during the production process is a must in every process. The main aspects that need to be paid attention to include avoiding various defects during wood veneer slicing. Natural defects such as stuttering, cracking, and black centers should be adjusted in the production process to avoid them. Processing defects require production personnel to constantly check the quality of wood veneer during production and make adjustments, such as internal cracks, knife marks, famine, etc.

The second is the moisture content of wood veneer, also known as moisture content, which is an important task of the drying department. Generally, various types of wood veneer have specific moisture content setting ranges. During the drying process, the operating speed or temperature of the drying machine should be adjusted at any time based on the moisture content of the wood veneer. It is necessary to check whether the moisture content of the wood veneer is qualified at any time. As long as the above items can be strictly followed according to the operating standards, the quality of the wood veneer will be well guaranteed.

In summary, the details that must be paid attention to in wood veneer processing that affect quality include: log selection, log preservation, and sawing.
