1. During the melting process, the temperature is too high or the bottom of the thermoplastic kneader is burned. The solution is to strictly control the temperature and clean the bottom of the thermoplastic kneader before operation.
2. The paint itself is of poor quality. It is likely that the paint has deteriorated. Before applying the batch of paint, it should be tested in a professional testing department. Only after passing the test can it be used for construction.
