1. The bonding force between the rubberized surface and the adhesive

        Self-adhesive trademark printing of the self-adhesive trademark of the film as the surface material, the low bonding strength between the rubberized surface and the adhesive is an important factor causing the residual glue and the glue. To increase this bonding force, it is necessary to treat the rubberized surface of the film before applying the glue, one method is coating treatment, and the other method is corona treatment.
        2, the moisture content of the adhesive and the content of the cured product
        They are also important factors influencing the binding force, so it is necessary to control the ratio between the two. The cohesive force of the adhesive is another factor to be aware of. The lower the cohesive force of the adhesive, the higher the possibility of overflowing. This requires attention.
        3. Adhesive fluidity and coating amount
        The stronger the fluidity of the adhesive on the sticker, the easier it is to produce glue. When the temperature is high, the fluidity of the adhesive is also good, and the initial viscosity is stronger. Especially in the environment of high temperature and high humidity, the fluidity of the adhesive will be greatly increased. Therefore, in the summer and rainy seasons, it is a frequent season of overflowing rubber problems. Therefore, at this time, pay more attention to the self-adhesive trademark material in the warehouse to avoid overflowing. phenomenon.
        4, high temperature environment is easy to trigger overflow
        In the high temperature environment, it is easy to occur in the self-adhesive trademark overflow glue. At this time, the high temperature resistant self-adhesive trademark material should be used for the self-adhesive trademark printing machine to avoid the overflow of glue. The high temperature resistant self-adhesive trademark material can be used in the silver ink layer of digital cameras, screen printing machines, and the like.
        The above are four factors that affect the adhesive printing machine's overflow. When using the self-adhesive label printing machine, we need to deal with the self-adhesive trademark material, effectively avoiding the adhesive label printing machine overflowing the glue and improving the machine production. quality.
