Change, corrode etc..Wherein SiO2Film density is 2.1g/cm3, refractive index is smaller, wear-resistant and corrosion-resistant, is a kind of important deielectric-coating.
However, this low emissivity glass radiant state is fixed, color is fixed, can not be carried out according to ambient climate environmental change and individual demand
Artificial regulation.Therefore existing Low-E glass radiances value is fixed, and scope is between 0.1-0.3, and color is single arbitrarily to be adjusted
Control.
The content of the invention
The invention aims to solve existing Low-E glass radiances value to fix, color is single asking of can not arbitrarily regulating and controlling
Topic, and a kind of Intelligent Dynamic Color tunable section Low-E glass is provided.
A kind of Intelligent Dynamic Color tunable section Low-E glass, it, which is utilized, adheres to SiO2Orderly monofilm ito glass, electrolysis
Matter layer film and clean ito glass are assembled by sandwich structure, and the surrounding of Intelligent Dynamic Color tunable section Low-E glass
Sealed using solidification glue, dielectric substrate film places attachment SiO in the Intelligent Dynamic Color tunable section Low-E glass2In order
In the middle of monofilm ito glass and clean ito glass, and attachment SiO2The attachment SiO of orderly monofilm ito glass2Orderly monofilm
The conductive side of side and clean ito glass is to placement.
Advantage of the present invention：
First, a kind of Intelligent Dynamic Color tunable section Low-E glass development prospects of the invention are wide, dynamically adjustable with color
The Low-E glass of section can meet the individual demand of people, can voluntarily be adjusted according to the need for user.
2nd, the present invention changes Low-E glass mediums layer, the pattern in reflecting layer, realizes electrochromism and low emissivity glass
Dual combination.Embodiment is simple and easy to apply, practical.
3rd, when a kind of constant voltage of Intelligent Dynamic Color tunable section Low-E glass application of the invention is in -0.2~-1.0V
When, with the increase of sedimentation time, glass can be blueness from pink colour transition.When applying backward voltage, will gradually it fade to be colourless.
When a kind of Intelligent Dynamic Color tunable section Low-E glass of the invention applies constant voltage in -1.2~-2.0V, during with deposition
Between increase, glass can be changed into pink colour again from yellow transition red, apply after backward voltage, can gradually fade to be colourless.Cause
A kind of this Intelligent Dynamic Color tunable section Low-E glass of the invention is to realize the adjustable Low-E glass of dynamic color.
4th, the present invention, which solves existing Low-E glass radiances value, arbitrarily to regulate and control, and can not realize that dynamic color is adjusted
