Cooling furnace glass breakage is often caused because the glass can not withstand cooling furnace cooling. Reasons: 1. Original glass plate negative filamentous cracks in the glass. 2. Holes and corners of the glass in the appropriate treatment. 3. The heating time is too short or uneven heating furnace. 4. Quench air pressure is too large, especially when thick tempered glass, higher air pressure may cause a high-temperature slope of the glass surface and the center between cause glass breakage. 5. Gate grid apertures wind wind not smooth, hair process, a region without a suitable cooling effect glass color glass, and quickly cooling the surrounding, so that the tension in the different glass breakage. 6. Broken glass wind gate collisions. Solution: Check the glass sheet. Drilling slotting proper polished glass. Increasing the heating time. Steel thick glass, the shaft-type fan, slow cooling, in order to avoid too much tension in the air pressure, damage. Check the wind gate clogging and cleaning. Increase placed a distance, reducing turnaround time. Currently dimming glass processing methods on the market, there are three: a direct film, laminated film .EVA two, three .PVB laminated film. Our company produces dimming glass way for PVB laminated electrochromic glass, conventional varieties are: 1. 6mm tempered white glass + 0.76PVB film liquid crystal film +0.4 + 0.76PVB Film + 6mm tempered white glass, with a total thickness of about : 13.92 mm. 2. 6mm white glass + 0.38PVB film liquid crystal film +0.4 + 0.38PVB Film + 6mm white glass, with a total thickness of about: 13.16mm. Where the original piece of glass in Shandong Jin Jing discoloration dimming glass, thickness 4mm, 5mm, 6mm, 8mm. PVB film imported high quality products discolored glass, liquid crystal film for Korean or American brands. Color as the transparent color. Where the original glass (including origin, color, thickness), the liquid crystal film can be customer specified brand for processing.
