How to Solve the Problem of Edge Banding Whitened Trim on Chinese Furniture143

Edge banding technology is widely used in the furniture industry, and it is an important process to improve the appearance and durability of furniture. However, in the process of edge banding, there will inevitably be some problems. One of the most common problems is edge banding whitening. Edge banding whitening refers to the phenomenon that the surface of the edge banding material becomes white after the edge banding process. This problem not only affects the appearance of the furniture but also affects the service life of the furniture. Therefore, it is necessary to find effective solutions to solve the problem of edge banding whitening in the production of Chinese furniture.

Causes of Edge Banding Whitening

The causes of edge banding whitening are complex, and the following are some of the main reasons:
The temperature of the edge banding machine is too high. When the temperature of the edge banding machine is too high, it will cause the edge banding material to be scorched, resulting in edge banding whitening.
The pressure of the edge banding machine is too high. When the pressure of the edge banding machine is too high, it will cause the edge banding material to be squeezed, resulting in edge banding whitening.
The speed of the edge banding machine is too fast. When the speed of the edge banding machine is too fast, it will cause the edge banding material to be heated unevenly, resulting in edge banding whitening.
The quality of the edge banding material is not good. If the quality of the edge banding material is not good, it will be more prone to edge banding whitening.

Solutions to Edge Banding Whitening

In order to solve the problem of edge banding whitening and master how to solve this problem, you can adopt the following methods:
Control the temperature of the edge banding machine. The temperature of the edge banding machine should be controlled between 160°C and 200°C. If the temperature is too high, it will cause the edge banding material to be scorched, resulting in edge banding whitening. If the temperature is too low, the edge banding material will not be able to be bonded firmly, resulting in edge banding falling off.
Control the pressure of the edge banding machine. The pressure of the edge banding machine should be controlled between 0.8MPa and 1.2MPa. If the pressure is too high, it will cause the edge banding material to be squeezed, resulting in edge banding whitening. If the pressure is too low, the edge banding material will not be able to be bonded firmly, resulting in edge banding falling off.
Control the speed of the edge banding machine. The speed of the edge banding machine should be controlled between 12m/min and 18m/min. If the speed is too fast, it will cause the edge banding material to be heated unevenly, resulting in edge banding whitening. If the speed is too slow, it will reduce the production efficiency.
Choose high-quality edge banding materials. The quality of the edge banding material has a great impact on the edge banding effect. Therefore, it is necessary to choose high-quality edge banding materials when purchasing.
Regularly maintain the edge banding machine. Regular maintenance of the edge banding machine can ensure that the machine is in good condition and reduce the occurrence of edge banding problems.

By adopting the above methods, the problem of edge banding whitening can be effectively solved. In addition, it is also necessary to pay attention to the following points in the process of edge banding:
Clean the surface of the substrate before edge banding. The surface of the substrate must be clean and free of dust, otherwise it will affect the bonding strength of the edge banding material.
Apply glue to the surface of the substrate before edge banding. The glue can improve the bonding strength of the edge banding material and prevent the edge banding material from falling off.
Press the edge banding material firmly after edge banding. Press the edge banding material firmly to ensure that the edge banding material is bonded firmly to the substrate.

By paying attention to the above points, the quality of edge banding can be effectively improved and the problem of edge banding whitening can be avoided.
