Analysis of composite membrane for common problems in the process of production

question reason:

1, the composite film thickness uneven, its thickness difference is too big.

2, product position deviation, lead to fold composite membrane, and as the accumulation of skewness, produce the extent of the fold will increase accordingly.

3, if the composite film is easily affected by the moisture film materials ( Such as nylon membrane) And occurred the phenomenon of moisture absorption and prone to fold in the composite extrusion process.

4, tension setting and improper control, tension not harmonious, the parts do not match.

5, composite pressure Settings.

6, silicone rubber between cooling steel roller and press roller's axis is not parallel.

7, guide roller surface is not clean, with foreign body, or guide roller surface is not flat, there are pits, his way, the phenomenon such as touch bad.
