Technical Field

The invention belongs to the technical field of preparation of colored toning glass, and particularly relates to a preparation method of colored toning glass.

Background

The dimming glass is formed by firmly bonding a dimming film between two pieces of float glass through an interlayer central film.

Because the laminated glass production process is adopted, the intelligent dimming glass has the characteristics of 'open and closed when electrified and light transmission when power off' and various characteristics of the laminated glass.

The power-on is on, the power-off is transparent, and the light transmission is not on: this feature is primarily due to the "electro-optic effect" of the liquid crystals in the light modulating film. More specifically, there is a liquid crystal molecule (PDLC) which is scattered and becomes frosted when no electricity is applied; when the power is applied, the liquid crystal molecules are instantaneously aligned, and the presented condition is instantaneously clear.

The film in the intelligent dimming glass firmly bonds the glass, so that when the intelligent dimming glass is impacted and broken, glass fragments are stuck on the film at the center, and the glass fragments cannot splash to hurt people.

The light adjusting film and the film in the center of the intelligent light adjusting glass can shield more than 90% of infrared rays and more than 99% of ultraviolet rays. The infrared ray shielding can reduce heat radiation and transmission; and the ultraviolet rays are shielded, the indoor furnishings can be maintained without fading, aging and other conditions caused by ultraviolet radiation, and the maintainers are not suffered from diseases caused by direct irradiation of the ultraviolet rays.
