When using High-Speed Local UV Varnishing Machine, what are the problems?

         1high-site Local UV Varnishing Machine's normal use temperature is 50-55 ° C. When use in low temperature in winter, it needs to be heated with UV optical oil in a constant temperature waters to achieve the viscosity of the design and use, which is conducive to UV light. The oil flow is calm and quickly solidified.

         2. High-Speed Local UV Varnishing Machine, the best temperature should be 50-60 ° C when passing through the UV light radiation area, because UV optical oil is cured quickly at this temperature, and strong attachment is strong after curing. In other words, the lower the temperature, the lower the temperature is under the Ryenste UV light. Especially in the winter low -temperature plant light, the adhesion is not good and the flowing level is not good. The main reason is that the temperature is too low and the solidification effect is poor.

         3.High-Speed Local UV Varnishing Machine should be placed in a position that the sun cannot directly illuminate, otherwise UV optical oil will be solidified on the coating roller under the action of ultraviolet light in the sun. If you can't avoid direct sunlight, you should also use red and black curtains to block the sunlight.

         4. The UV optical oil that is scratched when light is on the light will bring the ink that has been printed on the printing material to the UV light oil on the light machine to make the upper light oil on the color. Oil can be continued.

         5. The light causes and diluents in UV optical oil have a certain stimulating effect on human skin. Therefore, in the upper light operation, if the skin encounters UV light oil, wash it off immediately with soapy water, otherwise the skin may appear red, swollen and foam.

         6. The viscosity of UV Optor Oil varies from the type of light machine on the upper light machine of UV. The special optical oil should be selected according to the model of the optical machine. If the UV photoresmal viscosity does not meet the viscosity required by the upper light machine, it can be removed with a diluent or a thickener. However, this adjustment will lose the curing speed, brightness, and adhesion of UV optical oil. It is not recommended to change the appropriate dedicated optical oil as much as possible.
