Glass screen printing ink adhesion is that several factors

Factors influencing the glass screen printing ink adhesion is that a few? A, the bottle material printing material if the material is not pure, so have a considerable influence on adhesion, in the printing material on the market at present is not pure in synthesis and shuikou material. Again when in injection molding process in different companies and lead to present different plastic surface condition, there are a lot of material surface have grease, thus affect its adhesion. The color of the bottle material also has effect on receiving ultraviolet (uv) light, which may also affect its adhesion. Second, bottles of prepress processing in order to obtain good adhesion of printing ink to printing substrates, must carry on the polarization treatment on the bottle, bottle surface tension to make its surface tension is not lower than 3. 8× 10 - 2N/m( In general, the printing ink adhesion to substrates have good substrates surface tension is the most basic conditions for at least 50 dyn/cm) above 。 Polarization treatment method is mainly the flame was carried out on the bottle. Flame treatment its principle is by high temperature plastic surface decontamination, and melt surface membrane layer, thus can improve the surface of the plastic bottles, to improve the surface printing ink adhesion performance. To sum up, make sure substrates before printing surface clean and effective polarization treatment, surface treatment of the bottle is not complete, will inevitably have an impact on adhesion.
