PVB intermediate film production line: The secret of transparent protection of the artifact

PVB intermediate film production line, this seemingly ordinary production equipment, actually plays an important role in our daily life. From mobile phone screens to car glass, from medical devices to electronics, PVB intermediate membranes are everywhere. So how on earth does this seemingly simple production line produce such an important product? This article will take you to find out.

Introduction of PVB intermediate membrane

PVB intermediate film is a transparent polymer material with high transparency, high strength and good toughness. It is usually used in laminated glass, providing a layer of safety and comfort for our lives. PVB intermediate membrane is widely used in construction, medical treatment, electronics and other fields.

Second, the composition of PVB intermediate film production line

PVB intermediate film production line is mainly composed of the following parts:

1. Melt extruder: melt the raw material polymer and extrude it into silk to form the initial form of PVB intermediate film.

2. Cooling traction device: the extruded silk is cooled and pulled into a film, and the thickness and width of the film are controlled.

3. Composite equipment: two pieces of glass or plastic film and PVB intermediate film are combined together to form laminated glass.

4. Cutting equipment: the composite laminated glass is cut to meet the needs of different sizes.

5. Packaging equipment: Package the PVB intermediate film after cutting, which is convenient for storage and transportation.

Three, production process and technical points

1. Raw material preparation: The main raw material of PVB intermediate film is polymer, and the quality and purity of the polymer need to be strictly controlled in the production process.

2. Extrusion molding: The polymer is melted and extruded into silk by melting extrusion machine, which requires precise control of extrusion speed and temperature to ensure the shape and performance of the silk.

3. Cooling and traction: The cooling traction device will cool the extruded wire and pull it into a film, which requires control of the temperature and flow of the cooling water to ensure the thickness and toughness of the film.

4. Composite and pressing: composite equipment will be two pieces of glass or plastic film and PVB intermediate film composite together, and through high temperature pressing, so that the material closely combined to form a laminated glass with high strength and toughness. This process requires precise control of the pressure and temperature of the compound to ensure the quality and performance of the product.

Fourth, the automation and intelligence of the production line

The modern PVB intermediate film production line has realized a high degree of automation and intelligence, and the production process is monitored and managed through the computer control system. At the same time, the production line also adopts advanced online testing and quality control technology to ensure the consistency of product quality and performance.

Summary: PVB intermediate film production line seems simple, but it contains many scientific and technological elements. From the preparation of raw materials to the production of products, every link needs strict control and fine operation. It is these fine processes and technologies that make PVB intermediate membranes an indispensable part of our lives. Understanding the production process of PVB intermediate membranes helps us better understand this seemingly ordinary material and the important role it plays in our lives.
