Laminated glass is a specialized glass type widely used in modern architecture, automotive, defense, and maritime sectors due to its safety and performance properties. The polyvinyl butyral (PVB) film placed between two glass layers prevents shattering upon impact and keeps glass fragments together. The PVB film filters ultraviolet rays, protecting interiors from UV damage. This offers advantages in durability, safety, and aesthetics.
During lamination, moisture trapped between glass layers degrades visual quality through fogging or white spotting, creating aesthetically unacceptable products. Therefore, industrial dehumidifiers must control humidity in lamination rooms. Moisture alters material properties, preventing the glass from meeting expected mechanical specifications or causing properties to deteriorate over time. Without dehumidification, defect rates increase, costs rise, production speed decreases, and overall efficiency suffers.
The PVB film layer is highly susceptible to moisture damage. When stored in humid environments, structural changes or bubble formation can occur. Therefore, maintaining PVB at ideal humidity levels is essential. Industrial dehumidifiers ensure proper PVB storage conditions, preventing such problems. Lamination rooms must maintain controlled-environment clean room conditions with no dust, dirt, or moisture.
G4-F7 filters capture large particles while H13-H14 HEPA filters capture smaller particles, maximizing air quality. Positive pressure ventilation prevents contaminated external air from entering the room, preserving lamination quality. This ensures ideal conditions, improving product quality and durability. Dehumidifiers maintain constant humidity levels, allowing PVB to operate optimally.
