Xi'an Longfeng Plastic Printing Co., Ltd .: How can the printed polyester film be anti-adhesive?
Hefei Government Printing: find the reasons from three aspects: the proportion of corona, special ink and solvent.
Yueyang Jiali Xiaochen: The two solutions are different after anti-adhesion after rewinding or anti-adhesion during printing.
Hebei Qicai Wang Sheng: It is estimated that after the rewinding.
Guangzhou Parker Liu Changwen: Drying is not good.
Yueyang Jiali Xiaochen: The solvent ratio is changed, the temperature is increased, and the speed is changed.
Hefei Government Printing: Poor drying is related to solvent ratio.
Xi'an Longfeng Plastic Printing Co., Ltd .: The ratio of polyester solvent is toluene: isopropanol: ethyl ester = 3: 3: 4.
Yueyang Jiali Xiaochen: There is a distinction between quick and slow work.
Guangzhou Parker Liu Changwen: Check oven heating and air volume. Also check that the solvent formulation is correct. Why is your isopropanol so much?
Yueyang Jiali Xiaochen: Toluene is not necessary. You need a quick-drying solvent ratio, and then increase the oven temperature.
Guangzhou Parker Liu Changwen: If such a solvent ratio cannot be changed, either increase the temperature and increase the air volume, or reduce the speed.
Xi'an Longfeng Plastic Printing Co., Ltd .: Tension 40, oven temperature 55 ~ 60 ℃.
Hefei Government Printing: If the temperature is too high, it will not work.
Guangzhou Parker Liu Changwen: Increase air volume.
Xi'an Longfeng Plastic Printing Co., Ltd .: Thank you, the problem has been solved.
