PUR laminating machine laminating quality, how to choose PUR laminating machine?
Bonding quality of PUR overlaying machine
Bonding quality refers to the impact resistance and adhesion of finished paperboard. These two indicators are directly related to the adhesive. It is based on the use of quick drying rubber powder, which is explained in detail.
Adhesion is the adhesive strength between the base paper and the facial paper. A good adhesive finish is a mixture of paper and paper. While the immersion level too deep will cause significant Leng; shallow will cause bonding is not real, is what we often say the mouth is open too shallow fry. This requires that the glue should be spread evenly over the corrugated paper, and that enough paper should be immersed in the depth.
A simple set of verification methods is introduced here. First of all, the glue evenly on the edge of corrugated paper, that is, more than 1/3 of the height of the roll, to ensure that the hand in the corrugated paper on the surface of the painting, there is a clear sense of glue. Secondly, corrugated paper and paper adhesive, pressing pressure after delivery before half finished out, complete separation of paper and bottom paper, observe the tissue glue on the track, in the transport roller pressure for the case of the glue should be a continuous line of gel column. When bigger, this rubber mark is a glue mark with a certain width; when it is too big, there will be two glue marks with smaller width; too small, the rubber trace will appear as a discontinuous glue column line.
