What is electrochromic glass

Electrochromic glass. By pressing the button, the electrochromic glass will undergo a reversible, stable color change. This is because the electrochromic material in the glass under the action of applied voltage or electric field, the valence state and group of the material undergo reversible changes, so that the optical properties of the material, such as light transmittance, reflectivity, absorption rate, etc., are changed, which is manifested as changes in color and transparency in appearance. Disadvantages of electrochromic glass

1. High price: electrochromic glass needs to be coated with multiple layers of special materials on the surface of the glass, coupled with high manufacturing costs, limited market demand and other factors, resulting in high product prices, difficult to popularize.

2. Complex construction: electrochromic glass is more complex than ordinary glass. Because electrochromic glass needs to install additional equipment such as power supply and control system, professional and technical personnel are required to operate, resulting in difficult construction and high cost.

3. Short service life: the service life of electrochromic glass is shorter than that of ordinary glass. Due to the reasons of the manufacturing material itself, electrochromic glass is prone to problems such as uneven color change and aging, which affect the use effect and life.

4. Low energy efficiency: Although electrochromic glass can adjust color, its energy efficiency is still low. Due to the energy consumption and the rate of color change caused by the installation of power supplies is relatively slow, the energy efficiency of electrochromic glass is far less than that of other energy-saving materials.

5 Size limitation: the maximum width of the dimming glass is limited by the middle dimming film, the maximum width of the dimming film is 1.8m, so the widest glass can only be 1.8m, and generally speaking, the larger glass is not convenient in production and transportation, it is recommended that you can split it

6 Operating temperature limit: Dimming glass can only be used normally in the environment between -30 ° C and 50 ° C, if the temperature is too high or too low will affect the life of dimming glass, for example, dimming glass is exposed to high temperature above 60 ° C all year round, which will cause the liquid crystal molecules to gradually damage. In the scenario below -30 ° C, if the glass is electrified, it may also show a state of atomization

Advantages:

1. Fast speed of change: electro-tinted light glass is essentially made of glass, so it also has the characteristics of glass light transmission, and the time from atomization to transparency is only 0.2s when in use, and the dimming glass can also be used as a projection screen in the state of atomization

2. Safety protection: Since the dimming glass is also made of laminated glass process, when the dimming glass is impacted, the glass will continue to stick to the glass even if it is broken because of the PVB sandwich layer added to it and will not fall and cause injury

3. Energy saving: dimming glass is used in the use of a 60v AC, a square of glass only needs 2 degrees of electricity per month, it can be said that it is really energy-saving and because it is made of sandwich + film process, it also has a sound insulation effect, but also can shield more than 92% of the ultraviolet, infrared insulation off most of the heat radiation conduction
