Influence the cause of the composite film transparency is drunk so much!

Result the reasons affecting the transparency of the composite membrane, not only have printing reasons, if the adhesive is not up to standard, such as its color is deeper, illiquid, flow flat performance is poor, or cannot be fully spread out on the composite basement membrane, etc. ; And then there are technological reasons, this also is we the content of the speaker today. First is that if the working environment of the dust in the air is too much, after the glue drying and will have the dust in sucked in air, stick to the surface of rubber compound or sandwiched between two layers of basement membrane, a lot of dust can cause opaque or transparent. We the countermeasures are: closed compound on the plastic parts, drying tunnel inlet with high mesh filter, blocking dust sucked into. Secondly is if you don't clean rubber roller or rubber roller exhibition, exhibition will make composite membrane is not bright, or composite enough glue, glue is not uniform and has a blank space, with the tiny bubbles and can cause petals or opaque. To our decision is to check the adjustment on the contest, their feet and uniform coating. Composite basement membrane is not enough, the surface tension of the adhesive solution for its invasion is not enough, after the dry film is not even, also causes common & other; Pockmarked face film & throughout; 。 Finally, if the composite hot blast temperature is not enough, the hot melt glue part cannot high melting temperature, cooling roller, failed to sudden cooling, will lead to poor composite film is transparent. We countermeasures are: hot blast temperature is not less than 700 c, hot melt of the colloid began to melt when the temperature reaches 650 c, transparency not only improve after melting, and composite fastness is increased. Cooling roll chilled or frozen water cycle cooling is used, the faster the cooling speed, is the better transparency, composite film flatness is better, strong degree is, the better.
