PVB Laminated Smart Glass
What is Smart Glass?
Smart glass, also known as intelligent glass or electrochromic glass, is a high-tech material capable of altering its transparency. Unlike traditional glass, its transparency can be changed through external control, making it versatile for various applications.
Working Principles of Smart Glass
The working principle of smart glass is based on electrochromic technology, which is an electrochemical process. A special material, typically a smart film, sandwiched within the glass, can change its molecular structure when subjected to an electrical current or voltage, thereby altering the glass’s transparency. When an electrical current is applied to the glass, the molecules within the smart film rearrange, making the glass opaque. Conversely, turning off the current returns the molecules to their original state, restoring the glass’s transparency.
Forms of Smart Glass
1. Self-Adhesive Film Smart Glass
Self-adhesive smart film is a new type of functional film that adds an optical grade doubled-sided cling layer on one side of the normal smart film. Due to its excellent bending ability, it can be affixed on the existing flat glass or curved glass, providing a simple and cost-effective alternative for users.
It not only maintains all the original good characteristics of the smart film but also has “dry paste, self-exhaust” features that make the installation easy and fast.
2. laminated Smart Glass
The laminated smart glass is an innovative opto-electrical laminated glass that is composed of two layers of toughened glass on the outer side, a smart film in the middle, and other composite materials (PVB Film) to form a sandwich-like structure. All those materials stick together firmly through a special lamination process. When power off, it is opaque; when power is on, it turns transparent instantaneously. In addition, it is also a safety glass and can act as a smart projection screen.
3. Double Glazed Smart Glass
The double-glazed smart glass, also called insolating smart glass, is an innovative opto-electrical isolating glass that presents different visual states by controlling the voltage. When no voltage is applied, the glass is opaque, and when voltage is applied, the glass turns transparent, allowing the dual function of either high transparency or privacy protection.
It consists of two pieces of glass, one of which was affixed with a smart film, being separated evenly by a spacer and sealed around the surroundings. Among the two pieces of glass, a dry air space is formed, not only providing protection for the smart film but also enabling the glass to have good sound insulation and heat resistance features.
