Reinforced laminated glass processing technology: first clean glass stains dust, keep dry. Set up glass and film and combine silicone bags. After the combination of glass placement, the glass around the screen, for example, sack pieces. Good for vacuuming and prevent glass edge from breaking silicone bag. Combine the plastic bag, start the vacuum pump, and cold pump for 1-2 minutes to make the vacuum value above 0.090Mpa. Repropulsion heating box.
Bubbles are generated because the surface flatness of reinforced laminated glass is poor, the thickness of the film is greater than the overlapping deformation scale of two pieces of glass, the film is not completely melted, and the temperature in the box is increased or the holding time is extended. Stop vacuuming too early. Stop vacuuming only when the temperature is below 50 ° C. If the vacuum bag leaks, replace the silicone bag to ensure the operation of the vacuum pump and make the vacuum degree reach 0.090Mpa.
Degumming phenomenon, because processing temperature or holding time is not enough, according to the process requirements. Reinforced laminated glass surface is not clean, clean glass surface dirt. If the film is invalid, ensure that the film is used within the expiration date and is used up as soon as possible after opening.
