The main reasons of edge banding degumming
The main reasons are as follows:1, edge degumming is the main processor is too thin especially PVC edgebanding gum (agent) coating is too thin, and the decline of the hot melt adhesive affinity, which is one of the main reasons of the edge degumming.2, is the technical problem of edge machine temperature does not reach the predetermined temperature, causing sticking edge and hot melt adhesive glue is not good, the general requirements of the temperature at 180 ~ 210 degrees, can be adjusted according to the operating environment temperature sealing machine. This is mainly to look at the problem of technicians, manufacturers must strictly check, this is the problem of manufacturers.3, that is, the edge of the machine is too thin glue, originally did not produce a qualified edge banding. This is also an important reason, because the temperature and glue is too thin, causing the phenomenon of degumming is also common, you can increase the amount of glue to solve. The manufacturer's main problem is the manufacturer's responsibility. Everyone wants to think about it.4, uneven plate may also cause banding off, this is also must pay attention to the problem, appear this reason can only explain the installation technical problems.
First, it should be in the dustSecond, inletThird, sun exposure
One is aging, two is bad installation, and three is poor quality!!
