PVB SGP film production line

Introduction to PVB Glass Laminated Film Production Line

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 the best 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 excellent sound insulation, light control, thermal insulation, thermal insulation, shock resistance and other properties, making it an ideal safety glass processing material in the world.

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

The PVB film production line of Suzhou Jinweier Machinery Co., Ltd., among the top three PVB manufacturers in China, all use Jinweier's PVB dry (over roll method) and PVB wet (over water method) film equipment. The first PVB film production line in India is also manufactured by Jinweier. 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.

SGP Hot Melt Adhesive Film Production Line Product Introduction

Suzhou Jinweier has developed a new generation of safety glass laminated film (SGP) production line based on its own processing experience in plastic extrusion sheet equipment and the integration of PVB film equipment upgrades.
Main process: Accurately measuring and uniformly mixing SGP raw materials and additives, plasticizing and extruding them through an extruder, and then obtaining the finished product through casting, cooling, traction, etc.
Equipment advantages: 1. Fully automatic weighing measuring device, ensuring high-precision feeding of various solid and liquid additives and raw materials. SGP belongs to the ionic intermediate layer, composed of ethylene methacrylate copolymer and a small amount of metal salt.
2. The low-temperature extrusion system ensures excellent film performance while ensuring sufficient mixing and plasticization.
3. The special design of the casting part solves the problems of sticking rollers and peeling.
4. Unique online tempering stress relief device.
5. Multiple tension control systems in the production line ensure smooth transportation of elastic sheets during cooling, traction, and winding processes.
6. Siemens PLC and industrial computer centralized control can easily achieve closed-loop control.
Characteristics of SGP: Firstly, compared with PVB film, it has greater strength and transparency, making it an excellent configuration for ultra white glass. 2、 The tear strength of SGP laminated glass interlayer film is five times that of ordinary PVB, and its hardness is one hundred times that of PVB. It is a good material for bulletproof glass. Application of laminated glass produced by SGP: bulletproof glass, explosion-proof glass; Mainly used for cash transport vehicles, prisons, banks, glass roofs, glass staircases (which can be well bonded to metal), handrails, and railings
