[Abstract]:

The spacing between narrow and long workpieces is too small; the edges and corners around the upper surface of the base plate are not chamfered; the spacing between the horizontal and vertical workpieces is not in a straight line, which increases the resistance of air flow; the set temperature is too high; the time to reach the set pressure is too long. In case of drawing white, the set temperature is too high; the time to reach the set pressure is too long; the line type is not suitable. The edge is not firmly adhered: the quality of the adhesive is poor; the activation temperature of the adhesive is too high; the temperature of the equipment does not reach the activation temperature required by the edge of the workpiece; the base plate of the workpiece is not suitable; the performance of PVC back glue is not good or there is no back glue; the glue has expired or the storage does not meet the requirements; the leakage or spraying method is improper. There are quality wrinkles, the distance between narrow and long workpieces is too small; the edges and corners around the upper surface of the base plate are not chamfered; the distance between the horizontal and vertical workpieces is not in a straight line, which increases the resistance of air flow; the set temperature is too high; the time to reach the set pressure is too long. In case of drawing white, the set temperature is too high; the time to reach the set pressure is too long; the line type is not suitable.
