Because the performance of edge sealing hot melt adhesive is affected by temperature, so in the process of edge sealing, temperature is a very important indicator. The hot melt adhesive temperature, substrate temperature, edge material temperature and working environment (semi-automatic edge banding machine workshop) temperature are very important edge parameters. In the semi-automatic edge banding machine because the glue is coated on the substrate, the temperature is too low the substrate will make the hot melt adhesive cure early, resulting in the glue can stick to the substrate, but it is not strong bonding material, the temperature of the substrate adhere to more than 20°C.The working temperature of semi-automatic edge banding machine will affect the curing speed of glue. Factories often present banding problems in the season of low temperature. The reason is that the curing speed of hot melt adhesive is accelerated at low temperature, and the effective bonding time is shortened. Assuming that the feed rate of semi-automatic edge banding machine can not be changed (in most cases), it is necessary to preheat the plate and edge material to ensure the quality of edge banding.
