Screen printing glass ink paint off the reasons may involve many aspects, the following is a detailed analysis of these reasons:
1. material issues
Ink quality: the use of poor quality ink, its adhesion and curing performance may be poor, resulting in the ink on the glass surface can not form a strong combination, and then appear paint phenomenon.
Glass surface: If there are debris, grease, dust and other undesirable substances on the glass surface, or improper pretreatment of the glass surface (such as insufficient cleaning and decontamination), these will affect the binding force between the ink and the glass surface, resulting in paint peeling.
2. process issues
Printing technology: screen printing glass printing technology requirements are higher, printing pressure, printing speed, printing angle and other aspects of the master is not good may lead to the ink is not evenly, firmly attached to the glass surface, and then lead to paint.
Curing conditions: The curing of ink is an important part of screen printing glass. If the curing temperature, curing time and other conditions are not properly mastered, the ink may not be fully cured, thereby affecting its adhesion.
3. environmental issues
Environmental humidity: Excessive humidity may cause certain components in the ink to react with moisture in the air, thereby affecting the curing effect and adhesion of the ink.
Ambient temperature: The temperature is too high or too low may affect the curing and adhesion of the ink.
Air quality: dust and pollutants in the air may also have an adverse effect on the adhesion and curing effect of the ink.
4. the matching degree of ink and glass
Ink type: There may be differences in the binding force between different types of ink and different materials of glass. If the ink type does not match the glass material, the ink may not adhere firmly to the glass surface.
Baking temperature: The temperature released by the glass baking equipment is different from the matching temperature of the glass ink, which may also cause the ink to not be completely cured, and then paint peeling occurs.
In summary, the causes of screen printing glass ink paint may involve materials, processes, environment, and the matching degree of ink and glass. In order to prevent the occurrence of paint peeling, it is necessary to take corresponding measures to improve and optimize from these aspects.
