1, the use of solvents in water, alcohol, acid or ammonia, such as the content of impurities exceeded the standard, so that the glue disk life greatly shortened.

The main heat of the rapid volatilization of ethyl acetate from the surface during operation comes from the condensation heat of water vapor in the air, and the condensed water quickly melts into the rubber plate, further increasing its moisture content. This is particularly prominent in summer when the relative humidity of the air is greater than 80 %.

2,In addition, when it is hot and rainy, due to the volatilization and heat absorption of the solvent after the coating, the guide roll and the basement are cooled. The water in the air condenses into water droplets on the surface of the guide roll and the scraper surface, and drops back to the rubber plate. More and more water content, Causes turbidity and white hair. In the absence of a constant humidity device, the guide roller, scraper surface must be often wiped out, out of water droplets, to prevent the intrusion of condensed water.

3, there is also a possibility that when using a rapidly ripening adhesive, this glue is ripened too fast(4 to 6 H), and the matched glue will only take a few hours when the temperature is Gaohe's wet air weight. The cross-linking cure has been produced. Causes the operating solution to become turbid and white.
