How can winter plywood avoid cracking? This is essential knowledge
The temperature difference between the north and south of our country will affect the quality of the solid wood paneling process! In summer, everyone is relatively clear about the precautions for the panel factory, but once winter comes! Essential knowledge for winter board assembly that you must know!
With the arrival of cold waves in winter, the air is dry and the humidity fluctuates greatly, making solid wood spliced boards prone to deformation and cracking! Industry insiders all know that the requirements for solid wood splicing and solid wood thickening are very strict. In terms of humidity, temperature and other aspects, the influence of humidity is particularly obvious.

Five major Tips for Winter Board Assembly
The relative humidity value (%RH) has dropped sharply (due to abnormally dry weather)
After the panels are assembled, cover the removed panels with film to slow down the drying process. If conditions permit, it is better to install a humidifier in the cutting workshop.
When assembling thick boards, a test assembly should be conducted first to check if there are any gaps around the boards. If there are any gaps, the boards should be removed promptly.
3. Freshly planed and assembled: It is recommended that the time from planing to assembling the boards be within 1 to 2 hours. The fresher the wood is, the less it deforms, the less oil it secretes, and the stronger the penetration of the glue.
4. Extend the pressurization time as appropriate. In winter, when the temperature is low, it is necessary to extend the pressing time. Fushen suggests that the pressing time for thick plates should be more than 3 hours.
5. If conditions permit, when cold waves hit in winter, the air is dry and the humidity fluctuates greatly, it is recommended not to stack thick wooden boards for the time being. Wait until the environmental humidity and temperature are restored before resuming work to reduce the risk of rework due to product cracking.
