PVB SGP film extrusion line is divided into two types. One is the dry process, also known as the roller process, which is extruded by stretching the film, cooled in the air, and rolled. The other is the wet process, also known as the waterwheel method. The stretched film is cooled and extruded through a tank, and then blown to dry after winding.
PVB SGP film extrusion line is divided into two kinds. One is a dry process, also called the roll method of process, through the stretch film extrusion, cooling stereotypes winding in the air. The other is a wet process, also called watercraft, stretches film extrusion of film through tank cooling stereotypes, and blows dry after winding.
The equipment of the two processes is very different, and the price is also very different. The main machine can use a single-screw extruder or a parallel twin-screw extruder according to different needs and raw materials. PVB glass film production line and PVA film extrusion line are the core technologies of China GWELL.
PVB intermediate film is a translucent film, which is a polymer material plasticized and extruded by polyvinyl butyral resin with a plasticizer.
The appearance is a translucent film, free of impurities, flat surface, certain roughness,, and good softness. It has good adhesion to inorganic glass and has the characteristics of transparency, heat resistance, cold resistance, moisture resistance, and high mechanical strength.
It is the best bonding material for manufacturing interlayer and safety glass in the world. At the same time, it is used in building curtain walls, tents, windows, bank counters, prison visiting windows, steel furnace screens, and various bulletproof glass are also widely used in construction fields.

China Gwell Machinery Co., Ltd. is a professional manufacturer of PVB SGP film extrusion lines.
China’s top three PVB manufacturers are using Gwell’s PVB dry process (by roller) and PVB wet process (by water) film equipment. India’s first PVB film production line is also made by Gwell.
The shear mode of ionic film SGP is more than 50 times that of PVB, and the tear strength is 5 times that of PVB. When the laminated glass produced by the ionic film is stressed, there is basically no sliding between the two pieces of glass. The two pieces of glass are like one piece of glass, and the bearing capacity is twice that of PVB laminated glass. Under the condition of equal load and the same thickness, the bending of SGP laminated glass is only 1 / 4 of that of PVB laminated glass.
Compared with the laminated glass produced by PVB, the laminated glass produced by SGP film has better performance because it has the following properties:
|Extruder Type||Single screw extruder GWS150, parallel twin screw extruder GWP 95||parallel twin screw extruder co-extrusion GWP95+GWP52, GWP135+GWP52|
|Raw material||PVB, SGP||PVB, SGP|
|Layers||single layer||single layer, double layer or three layers|
Innovation drives enterprise progress. Relying on the group’s strong technology, equipment strength and innovation spirit, Gwell is committed to the development of high-tech products and the international market. Gwell also actively exchanges and cooperates with world-class scientific research institutions. The new technologies, new processes and new products developed by Gwell are widely used in building materials(PP hollow sheet extrusion machine, PC optic extrusion machine), home appliances(SPC floor extrusion machine), packaging(PET sheet extrusion machine, EVOH film extrusion machine),
medical treatment(PVC rigid sheet extrusion machine), automobiles(TPU film extrusion machine, PVB film extrusion machine), new energy(EVA solar film extrusion machine), aerospace(TPU film extrusion machine), rail transit(waterproof film extrusion machine) and other fields, which are closely related to human life.
