1、 Definition of polyester film anti infrared film
Polyester film anti infrared film is a protective film that uses polyester film as the substrate and is coated with a layer of infrared reflective coating on its surface through special process technology. This film can effectively reflect infrared radiation, block the transmission of thermal energy, and thus play a role in insulation, energy conservation, and thermal insulation.
2、 Manufacturing process of polyester film anti infrared film
The manufacturing process of polyester film anti infrared film mainly includes the following steps:
1. Preparation of polyester film: Heat the polyester particles to a molten state and extrude them into a polyester film.
2. Preparation of infrared reflective coating: First, a layer of transparent adhesive is applied to the surface of the polyester film. Then, the infrared reflective material that meets the requirements is mechanically filtered and mixed in a certain proportion to form a reflective coating. Finally, the coating is evenly covered on top of the transparent adhesive to form an infrared reflective layer.
3. Coating the reflective layer: Apply a transparent coating to form a protective layer to prevent damage to the reflective layer.
4. Treatment of polyester film: Through subsequent processes such as blown film, cutting, and rewinding, polyester film anti infrared film is made.
3、 Characteristics of polyester film anti infrared film
1. Anti infrared: Polyester film anti infrared film can effectively prevent the penetration and reflection of infrared rays, playing a role in cooling and insulation.
2. High temperature resistance: The film can maintain its physical stability under high temperature conditions.
3. Chemical resistance: Polyester film anti infrared film has good chemical resistance and can resist the corrosion of chemicals such as acid and alkali.
4. Optical stability: Polyester film anti infrared film has good optical stability and can maintain the stability of its optical effect for a certain period of time.
5. Good organization: This film can be well combined with other materials, has strong adhesion, and can ensure the quality of product production.
4、 Application of polyester film anti infrared film
1. Construction industry: Polyester film anti infrared film can form a thermal insulation layer between the building and glass, effectively reducing the temperature inside the building and achieving the goal of energy conservation and consumption reduction.
2. Electronics industry: This film can be used as a protective material for electronic screens and displays, reflecting infrared radiation to prevent damage to electronic products due to overheating.
3. Automotive industry: Polyester film anti infrared film can be used as a suspended solar thermal insulation film for car windshields, effectively reducing the temperature inside the car, saving air conditioning power, and making driving more comfortable.
4. Food packaging: This film can also be used for food packaging, reducing the temperature inside the bag and extending the shelf life of food.
5、 Summary
In summary, polyester film anti infrared film is a protective film made by coating the surface of polyester film with an infrared reflective coating. It has the characteristics of reflecting infrared rays, energy saving and consumption reduction, high temperature resistance, chemical resistance, etc., and can be widely used in the construction industry, electronics industry, automotive industry, food packaging and other fields.
