Edge Banding Overall Color Change Principle227

The overall color change of edge banding refers to the phenomenon that the color of the edge banding changes as a whole, and the color change is uniform and consistent. This phenomenon is mainly caused by the following reasons:

1. Raw material problems: The raw materials of the edge banding may contain impurities or colorants, which will cause the color of the edge banding to change after heating and bonding. For example, some recycled materials may contain residual glue or paint, which will cause the color of the edge banding to turn yellow or black after heating.

2. Production process problems: The production process of edge banding may not be properly controlled, which will also cause the color of the edge banding to change. For example, if the temperature of the hot melt adhesive is too high, the edge banding will be scorched and the color will turn black. If the pressure of the press machine is too low, the edge banding will not be completely bonded to the substrate, and the color will be uneven.

3. Environmental factors: The storage environment of the edge banding may also affect its color. For example, if the edge banding is exposed to sunlight for a long time, the color will fade. If the edge banding is stored in a humid environment, the color will turn moldy.

To prevent the overall color change of edge banding, the following measures can be taken:

1. Strictly control the quality of raw materials: Choose raw materials that meet the quality standards and do not contain impurities or colorants. Recycled materials should be carefully selected and pretreated to remove residual glue and paint.

2. Strictly control the production process: Strictly control the temperature of the hot melt adhesive and the pressure of the press machine to ensure that the edge banding is properly bonded to the substrate. Regular maintenance and calibration of production equipment to ensure that the equipment is in good working condition.

3. Proper storage of edge banding: Store the edge banding in a cool, dry, and ventilated environment, and avoid exposure to sunlight and moisture. Edge banding should be properly packaged to prevent dust and other contaminants from entering.

By taking the above measures, the overall color change of edge banding can be effectively prevented, and the quality of edge banding can be improved.
