Now in our lives, glass has become an indispensable element of modern architecture. Whether it is glass doors and windows, glass partitions or glass sliding doors, or the exterior walls of high-rise buildings, glass can be seen everywhere. As a representative of safety glass, laminated glass is the best choice in many places. So what are the easy problems and reasons for laminated glass in the production and use process? Here will get the answer.
1) Small bubbles appear on the whole glass: check the working condition of the vacuum pump and the vacuum degree of the vacuum gauge, and check the sealing degree of the vacuum bag and whether the air passage is blocked.
2) Bubbles appear in the middle of the glass: The airway drainage and drainage have not been properly handled.
3) Bubbles appear around the glass: the high-temperature heating time is too long to shorten the high-temperature holding time.
4) Fog around the glass, accompanied by bubbles in severe cases: check the dryness of the glass, the dryness of the cover, and the dryness of the EVA film (pay attention to the baking or increase the low-temperature holding time).
5) The whole surface of the glass is uniformly foggy: it is necessary to increase the heat preservation time in the high-temperature section, or the film has quality problems (except for the normal film).
6) White mist appears locally in the middle of the laminated glass, accompanied by bubbles in severe cases: the cause of this problem is that the glass or film is wet or there are water droplets.
7) Long strips of large bubbles or bubble bands appear on the glass: it is caused by the uneven tempered glass, it is necessary to thicken the film, or choose two pieces of glass with good fit when combining the sheets.
8) When tempering and laminating, you should pay attention to the matching tempering when the glass is tempered, and keep the curvature consistent (try to put the two pieces of glass to be laminated in the same position and temper, and the direction must be the same; punching, opening, and special shape Pay special attention to the glass.)
9) When two different types of tempered glass are laminated (such as 8mm 5mm, tempered white glass tempered tea glass, ordinary float glass tempered glass, etc.), a film of sufficient thickness must be selected.
