PVB film is a semi transparent film that has good adhesion to inorganic glass. It has characteristics such as transparency, heat resistance, cold resistance, and high mechanical strength, making it an excellent adhesive material for manufacturing laminated glass. PVB film can absorb impact energy without producing broken pieces. This safety glass is widely used in automobiles, high-rise buildings, bank counters, various bulletproof glasses, etc. In addition to its safety performance, it also has good sound insulation, light control, thermal insulation, thermal insulation, shock resistance and other properties, making it an ideal material for safety glass processing.
The main purpose of PVB film production line is:
1. PVB automotive safety glass film production line: PVB film is mainly used as the middle layer of automotive front windshield
2. PVB Building Glass Intermediate Film Production Line: PVB adhesive film is mainly used for the intermediate layer of high-rise building glass
3. PVB solar film production line: The PVB film produced is used for packaging solar thin film cells
PVB film production line of Suzhou Jinweier Machinery Co., Ltd. PVB film width: 3600mm (max), PVB film thickness: 0.38-1.52mm, yield: 500-800kg/h, shrinkage rate: ≤ 2%, total length of production line: 28m. It can be cut into the required width according to user requirements, and this production line has the following characteristics:
1. Adapt to different types of processing in various material systems
2. From feeding to winding, automatic mixing, PLC full set integration, can do turnkey projects
3. High output, low energy consumption, and high degree of automation.
The PVB film production line is divided into two methods: one is the dry process, also known as the rolling process, which uses extrusion casting and air cooling to shape and roll the film; the other is the wet process, also known as the water passing process, which uses a water tank to cool and shape the extruded film, and then dries and rolls it. There are significant differences in equipment and prices between the two processes. The host can also use a single screw extruder or a parallel twin-screw extruder according to different needs and raw material conditions. Please consult the sales engineer for details. The PVB glass adhesive film production line is the core technology product of Jinweier Company.
