Reasons and Solutions for Cracking of Edge Sealing on Wooden Doors
The advantages of wooden doors - environmental friendliness, aesthetics, affordability, and a wide range of styles - have increasingly attracted consumers. However, with widespread production, some minor issues may arise. Today, let's discuss the reasons behind cracking of edge sealing on wooden doors and the solutions!
Reasons for the cracking of edge sealing strips on wooden doors:
The moisture content of the wood used for the edge sealing strip is inadequate (>18%), leading to natural drying and internal stress during door usage, resulting in phenomena like cracking and deformation of the edge sealing strip.
Improper ratio of adhesive and curing agent diminishes bonding strength. This issue isn't directly related to the quality of the edge sealing strip but is closely associated with construction and installation.
Failure in adjusting the ratio of adhesive and curing agent diminishes bonding strength, which is not directly a quality issue of the edge sealing strip but is largely connected to installation during the construction process.
Inadequate cleaning of the glue container affects the adhesive's bonding performance during installation, emphasizing the importance of proper glue adjustment during the installation of wooden door edge sealing strips.
The edge sealing issues of eco-friendly unpainted boards tend to manifest in adhesive separation over extended use. Utilizing the following methods can enhance the bonding between the adhesive and the edge sealing strip:
Cut the adhesive film to the required length, place the adhesive side facing down on the edge of the wooden board, and use a soldering iron to press it onto the board's edge. Then, peel off the release paper from the back, leaving the adhesive film attached to the board.
Apply the edge sealing strip onto the adhesive film and continue pressing with the soldering iron. Be cautious not to set the iron temperature too high as it may damage the PVC surface; temperatures below 140 degrees Celsius are sufficient.
After cooling, use a small planer to trim the edge, keeping it at a 20-degree angle from the board's surface to avoid damaging the board. Carefully trimming the edge completes the edge sealing of the unpainted board.
Edge sealing strips on unpainted boards may seem inconspicuous, but their impact is significant. Without them, furniture edges would be rough, causing discomfort during use and greatly reducing aesthetics.
