Temperature Of Semi-automatic Edge Sealer

Temperature of Semi-automatic Edge Sealer

Because the performance of hot melt adhesive is affected by temperature, temperature is a very important index in the process of edge sealing. The hot melt adhesive temperature, base material temperature, sealing material temperature and working environment (workshop where semi-automatic edge sealing machine is located) temperature are all very important parameters for edge sealing.

 In the semi-automatic edge-sealing machine, because the glue is coated on the base material, the base material with too low temperature will solidify the hot melt adhesive ahead of time, so that the glue can adhere to the base material, but it can not adhere to the edge-sealing material tightly. The temperature of the base material should be kept above 20 degree C. The working environment temperature of semi-automatic edge sealing machine will affect the curing speed of the adhesive. In factories, the problem of edge sealing often occurs in the low temperature season. The reason is that the curing speed of hot melt adhesives is accelerated and the effective bonding time is shortened at low temperature. If the feeding speed of semi-automatic edge sealing machine can not be changed (in most cases), to ensure the quality of edge sealing, it is necessary to preheat the sheet and edge sealing material.
