The application of glass film to improve the energy saving of ordinary float glass can be traced back to 1960, when the original intention of glass film was to control the imbalance of heating and cooling caused by solar load. Early films only had the property of reflecting solar radiation out of the glass window to prevent the increase of heat on the inner surface of the glass. With the continuous development of manufacturing technology, there are more and more types and styles of glass film, but there are two main types used in daily homes, one is glass film with self-adhesive, and the other is very special in recent years. The popular adhesive-free electrostatic glass film.
These two glass films have their own characteristics, how should we choose when we buy glass films? First understand the difference between these two glass films:
1. Adhesive-free electrostatic glass filming characteristics: 1. Adopting adhesive-free, electrostatic adsorption process. 2. Environmental protection, the product uses PVC raw materials, it will not shrink during preheating and cold. 3. Paste without adhesive, can be pasted repeatedly, and the film can be changed at will according to the interior decoration style or the season (the removed film and the transparent base film torn off before use are folded and stored properly, and can be used repeatedly, easy to use , Without other auxiliary materials, can be pasted by yourself). 4. Isolate ultraviolet rays, transmit light and opaque. 5. Fashionable color printing can better match your interior decoration style and create a colorful and fashionable living space. 6. The 3D stereo touch will transform into different colorful effects due to the different light and background.
Efficacy: 1. Energy saving and environmental protection, reducing high electricity bills caused by air conditioning and heating. 2. Protect privacy and let the living space enjoy peace and comfort. 3. Block the intrusion of ultraviolet rays and protect indoor items from fading and aging. 4. Improve building appearance and beautify indoor living environment. 5. Filter strong light, reduce glare, protect skin and eyesight. 6. Easy to install and paste, easy to clean, resistant to friction, no special maintenance. 7. Increase the strength of the glass, reduce personal injury and protect property. 8. Economical and practical, non-fading, non-foaming, long use time.
2. Principles of structure and performance of glued glass film: The basic composition of the film is: polyester substrate (PET), one side is coated with anti-scratch layer (HC), and the other side is installed with glue layer and protective film. PET is a material with strong durability, strong moisture resistance, high and low temperature resistance. It is clear and transparent, and has been processed by various processes such as metallized coating, magnetron sputtering, interlayer synthesis, etc., to become a film with different characteristics. Glue is a chemical raw material that will more or less volatilize into the air when exposed to the sun. Since the glue is more firmly attached, it is not easy to remove it over time. Replacement in the future is very troublesome and damages the glass.
to sum up:
Adhesive-free electrostatic glass film is easy to operate without worrying about the problems caused by glue. It is also convenient to replace in the future. It has many styles and good performance, but the price is slightly higher than that of glued glass film. Self-adhesive glass film with glue has more styles , And the width is large (1.2m wide), has the anti-explosion function that the electrostatic film does not have, and the price is relatively affordable. However, pasting is not as convenient as electrostatic glass pasting, and the problems of immovability and later removal of glue brought by glue pasting must be considered.
