Dimming switchable glass is a five layer laminated structure of "glass+eva film+pdlc+eva film+glass.".Ito-pet film, polymer and liquid crystal are combined into one layer, which is called "liquid crystal film".
Therefore, from the composition and structure of dimming switchable glass, I can know that the price of dimming switchable glass must be related to glass, film and liquid crystal film.
1, glass
There are 8 kinds of original glass sheet thickness suitable for dimming glass, including 5 + 5 (12mm), 6 + 6 (14mm) and 8 + 8 (18mm).
In the production of dimming smart glass, the requirement for the flatness of the original glass is very high. The larger the area of toughened glass is, the easier it is to bend, the less flatness it is, and the more difficult it is to process.
There are many kinds of colors for glass, ordinary white and ultra white for dimming smart glass, European grey, crystal grey, Ford blue and other colors are also selected by many users.
Thickness, size and color are the main factors affecting the price of smart glass.
2 .film
There are mainly two kinds of films for producing dimming smart glass, EVA and PVB. The two types of films not only differ in price, but also represent two different methods of laminating and use different processing equipment.
3. Liquid crystal film
The above glass and film are industry standard, but the liquid crystal film is not. So the liquid crystal film produced by each manufacturer is very different. Although the appearance is similar and slightly different, the light transmittance is high or low, the quality is good or bad, and the price range span is surprising.
Buyers can choose and customize dimming smart glass according to their own needs.
First of all, we need to determine where the glass is installed, what thickness and size are needed, then we need to know about the characteristics and quotation of the glass in the market, determine the price we can accept, and then find out which products of which companies meet our requirements.
Dimming switchable glass, you need to know not only the price, but also the quality and service that determine the product price. How to choose and compare requires some professional knowledge.
