Evolution of Light-Control Color-Changing Heat-Insulating Window Film
First Generation: Coating Process
Originating in the 1930s, this process primarily involved dyeing plastics, commonly referred to as "tea paper." This technique laid the groundwork for subsequent advancements.
Second Generation: Dyeing Process
Emerging in the 1960s, this generation included various types of films, such as glue-layer dyed films, membrane-layer dyed films, multi-color dyed films, and deep substrate dyed films. It significantly enhanced the color options and functionality of window films.
Third Generation: Thermal Evaporation Process
In the early 1980s, aluminum and metal-coated films were introduced. By the mid-1980s, this technology evolved into vacuum-deposited dyed composite films, improving optical performance and durability.
Fourth Generation: Magnetron Sputtering Process
By the late 1990s, various magnetron sputtering techniques were developed, including metal films, original color metal films, ceramic films, and spectral composite films. These advancements further enhanced heat insulation and light control properties.
Fifth Generation: Nanostructured Oxide Coating
In 2000, multi-layer plastic films were launched, resembling the structure of 3M's DBEF; in 2010, nanoparticle oxide coatings (such as WTO, ATO, ITO) were introduced, achieving new heights in light control and thermal insulation.
RIEOS Advantages
By integrating the fourth and fifth-generation technologies (magnetron sputtering and nanocoating), RIEOS has achieved a comprehensive enhancement in the performance of light-control color-changing heat-insulating window films.
Application Cases
In the construction industry, some green building projects have successfully implemented Light-Control Color-Changing Heat-Insulating Window Film (photochromic window film). For instance, in a high-rise office building, the use of this window film has significantly reduced the air-conditioning load and improved energy efficiency. User feedback indicates that the window film not only enhances the indoor lighting environment but also lowers electricity costs. These successful cases demonstrate that the application of Light-Control Color-Changing Heat-Insulating Window Film is both feasible and beneficial, yielding positive economic and environmental impacts.
