One.Facing panelWill it crack?
Generally, this is not the case. Veneer panels typically use a hardwood core, with a thickness of approximately 3mm. During manufacturing, the high strength and brittleness of hardwood require softening before cutting and shaping to ensure good workability and maintain a high yield. Therefore, the moisture content of the wood in the veneer panel must be higher for subsequent processing. Additionally, due to economic considerations, veneer panels typically have a very thin surface, which easily allows moisture to evaporate. When moisture evaporates, the wood shrinks, resulting in small cracks. Veneer panels are generally well-packaged upon leaving the factory to prevent moisture evaporation and warping or cracking.
Two. Causes of cracking in wood veneer.
1、The substrate surface is uneven due to inadequate sanding of the particle board material.
2、The wood veneer used is too thick. Veneer thicknesses of 0.5mm are generally not suitable for manual application, and the wood veneer has not been wetted. Typically, the thickness of wood veneer used in manual application is 0.3mm or less. Using excessively thick wood veneer can make manual application difficult and prone to problems.
3. If the ironing temperature is not properly controlled, ironing at too low a temperature can cause bubbling. In addition to the above issues, cracking during ironing can also occur due to ironing at too high a temperature, excessive ironing frequency, and short intervals between ironings.
4、The issue was using adhesive that did not meet the specified requirements, resulting in insufficient bonding strength or uneven application. Therefore, selecting high-quality adhesive is crucial for proper wood panel attachment.
Three. Solutions for cracking of decorative panels
based on the above analysis, the following points should be considered to prevent peeling, blistering, and cracking:
1. Ensure the substrate is properly prepared and smooth. Selecting a substrate that is flat and free from deformation is crucial.
2、The wood veneer applied manually should be no more than 0.2mm, preferably 0.2mm.
3. The ironing temperature should not be too low. It should also not be too high; the temperature needs to be appropriate.
