Heat treatment knowledge of veneer veneer

When producing veneer veneer paper, it is necessary to pay attention to heat treatment. If the treatment is not good, it will have a certain impact on the use.

When heat treatment, the first thing to pay attention to is the natural cooling and isothermal stage. During the processing, it is necessary to make its surface reach a certain heating temperature before making the wood core. The other part exceeds a certain temperature, so that it is taken out from the cooking tank, and it will also generate internal stress, so that it will crack. The second is the heat preservation stage. Before heat preservation, the temperature needs to be raised rapidly until it reaches the required temperature, and then heat preservation is carried out.

Then is the heating stage. Generally, it takes about 6-10 hours to raise the water temperature from 40 degrees to the specified medium temperature. In the process, it can be used better.
