subject: Glass That Change To Opaque [print this page] As there is a sudden changes in glass technologies being made in the recent past, which has prompted in creation of such a glass that can transform itself by controlling the amount of light and heat which passes through them. These are being termed as Smart Glasses and the made advantage why all glass manufacturer has suddenly agreed for mass production used in commercial fields is because of its less consumption of energy and over that blocking the light and in turn making the room much cooler. Over that these window pane with transform from transparent to opaque with pressing of a switch and provide an edge over contemporary glasses.
These glasses are so elegant that it provides you with a clear cut view of the things that are being visible behind these windows. As the main concept of these smart glasses are same, these glass manufacturers mould these glasses according to their likings, using different glass technologies and properties of complete blockage of light. Well there are three major techniques which include liquid- crystal, SDP or suspended particle device and finally electro chromic.
Now let us, discuss these three of them in details.
Liquid- Crystal
These glasses are found in the glass market in the form of laminated glasses which are either two clear or coloured sheets attached with a crystal liquefied sheet, being tightly assembled between two inter layers of plastic. When light is off or normal then glazing is slightly in milky white stage or rather opaque. But, once light is passed through them the glass becomes a little hazy in a translucent mode with partly clear view. The major demerits behind these glasses is that as these windows have less performance changing properties and requires constant flow of energy so as the clear view can be maintained. Thus, the benefit of saving energy is nil and the glass manufacturers have used this glasses to design partition, internal applications and bank screens.
SDP or suspended particle device
The glass technologies used behind this is different. The glass remains dark and opaque when the electric charge is not present in them and once being charged the molecules present inside them transforms themselves giving a clear cut transparent view. SDP or suspended particle device is smartly constructed with a couple of suspended conductive film, great light absorbing capacity and the macroscopic being arrested between the twin glass panes. Whats good is that these electro chromic glasses present inside these liquid crystal glasses can make the glass can either be transparent or be opaque. For that to take place these glasses too need to be regularly charged. There is no scope in between stages and the scatter lights that get reflected are being stopped so whatever behind the glass is going on cant be seen from outside.
Electro Chromic Glasses
A challenging technology used by the glass manufacturer using the SDP technology is being used behind the electro chromic glass manufacturing. It mainly consists of twin glass layer with various sandwiched layers in between. The working process solely depends upon passing through low- voltage charges on the electro chromic activated thin glass layers which changes from dark to clear when fully charged. The entire glass system works on electricity to convert its opacity, keeping it away from maintenance of any particular shades.
These different glass technologies used behind by the glass manufacturers is the most unique one and as time changes, new technology will develop, as a result different glass manufacturing technique would develop. That time will be the better judge to decide.
