What is the reason for the pitting on the surface of the product produced by the blister machine?

What is the reason for the pitting on the surface of the product produced by the blister machine?

Cause analysis:

1. The particle size of the glue is large, and the use of thin PVC film is easy to produce pockmarks. Such pockmarks are characterized by uniform dispersion;

2. When used with curing agent, the curing agent is not completely dispersed;

3. The surface of the plate is not cleaned, or after spraying glue, the workshop is dusty and sticky. The pitting is very uneven and varies in size;

4. The viscosity of the glue is too large and the dispersion is uneven;

5. The viscosity of the glue is too small or the solid content is low, causing the sheet to fluff. Such pitting generally appears at the corners of the groove and appears in blocks.

6. The air pressure of the spray gun is not enough and the atomization is not good.

7. Glue is not filtered (this case refers to: a bucket of glue is used to the end. If stolen goods fall into it or conjunctiva is generated, it should be filtered with a filter screen).

Solution:

1. Choose glue with small particle size;

2. With the curing agent, extend the mixing time, so that the curing agent can be completely dispersed;

3. Clean the surface of the plate before spraying glue, and separate the glue spraying workshop;

4. Choose the appropriate viscosity of the glue or high solid content of the glue;

5. After the glue is dry, it can be polished with fine sandpaper;?

6. Increase the vacuum degree and adjust the atomization effect;

7. When using, filter with a filter.
