The temperature of the hot melt adhesive, the temperature of the base material, the temperature of the edge banding material and the temperature of the working environment (the workshop where the woodworking edge banding machine is located) are all very important edge banding parameters during edge banding. If the substrate coating temperature on the semi automatic edge banding machine is too low, the hot melt adhesive will be cured in advance, resulting in the result that although the adhesive can stick to the substrate but not firmly, the temperature of the edge banding material substrate is the best Keep it above 20°C. The working environment temperature of the woodworking edge banding machine will affect the curing speed of the glue. The factory often has the edge sealing problem in the low temperature season. The reason is that the curing speed of the hot melt adhesive at low temperature accelerates the effective time of bonding.
When choosing edge banding, attention should be paid to factors such as width, thickness, material, toughness, and degree of surface treatment. For hot melt adhesives, pay attention to the difference between high, medium and low temperature adhesives, matching with the type of edge banding, and scientifically set the heating control temperature and the flowability and solidification delay of the sol. The selection of the base material also has quality, temperature, parallelism and perpendicularity requirements of the section. The indoor temperature and dust concentration of the working environment also need to be considered. Coherence, etc. will affect the edge banding effect.
If the semi automatic edge banding machine also has some of the above-mentioned faults during use, you can refer to the above-mentioned solutions, so that the occurrence of the fault can be solved more quickly without affecting normal work.
