Today, I will summarize the top ten issues in the deep processing of PVC printing film: there are many problems with PVC printing film in glass deep processing. Let's summarize for everyone's reference.

1. Insulation time: The insulation time is short, the adhesive components in the PVC printed film do fully react with the glass, making it easy to peel off; The longer the insulation time, the stronger the adhesion; The length of insulation time should be determined according to the characteristics of the equipment. Single layer furnace has a short insulation time, while double-layer multi-layer furnace has a long insulation time. For thick glass, thick decorative materials, thick PVC printed film, colored PET film, the insulation time should be appropriately extended.

2. Raise processing temperature: For thick glass, thick decorative materials, thick PVC printing film, colored PVC printing film, multi-layer furnaces, the processing temperature should be appropriately raised.

3. Extend insulation time: When the temperature reaches the processing requirements, the insulation time should be appropriately extended for the thickness of glass, decorative materials, PVC printing film, colored PVC printing film. The purpose is to allow the adhesive to fully bond with the glass on the PVC printing film.

4. Uneven temperature inside the furnace: Uneven heating of the glass affects adhesion, leading to delamination fogging.

5. Glass surface temperature hot air temperature (measuring point): The temperature at the measuring point outside the silicone bag is called the hot air temperature. Although the temperature inside the furnace meets the requirements, the temperature inside the bag is still very low cannot meet the processing requirements. It is necessary to extend the insulation time as much as possible to ensure that the temperature inside the bag meets the process requirements, fully undergoes bonding reactions, avoids delamination; If the temperature measurement point is referred to as the glass surface temperature in a silicone bag, it is easy to control the temperature holding time.

6. High temperature: ① The amount of glue flowing out is large, the amount of glue at the edges is small, which makes it easy to peel off produce bubbles; ② Easy to have lane chicken paw prints.

7. Low temperature: The adhesive in PVC printing film can fully react with the glass, which can easily cause delamination. Because each furnace has a different heating speed, space size, glass thickness, decorative materials, PVC printing film used, temperature measurement points, the processing temperature should be too rigid. The temperature should flow out slightly after the PVC printing film melts, but too much. Many (the thickness of the spilled glue is about 2 millimeters).

8. Single layer processing furnace Multi layer processing furnace: Single layer furnace heats up quickly has a short insulation time; Multi layer furnaces have slow heating long insulation time. In the production process, the processing technology should be explored adjusted according to the characteristics of the equipment itself.

9. Tempered laminated glass: Based on the level of glass tempering, customers should choose how thick PVC printing film to compensate for the unevenness of the glass. When combining, try to choose smooth surfaces that face each other.
