Problems solved by technology

For example, a gymnasium needs a lot of natural lighting when there is no daily event, and it needs to be completely shaded to facilitate competition activities during official competitions. The conversion of the internal space function of the gymnasium is realized by adding additional auxiliary equipment such as sunshade curtains to continuously transform the space function. Therefore, the investment of the building will be increased, and the construction of assembling the sunshade is loaded down with trivial details

Embodiment 1

[0033] A film with adjustable transparency, the outer two layers of transparent film layers are made of polytetrafluoroethylene, and the electric qualitative change layer is arranged between the two layers of transparent film layers. This film with adjustable transparency is used instead of glass in the In the sports training hall, the film with adjustable transparency is fixed by manual installation. When it is necessary to isolate the line of sight and light, the electric qualitative change layer is energized to change the transparency of the film with adjustable transparency, so as to block the line of sight and light. role.

[0034] In Embodiment 1, the film with adjustable transparency replaces glass for easy installation, and can realize the conversion of space functions according to actual needs, reducing costs.

Embodiment 2

[0036]A film with adjustable transparency, the material of the outer two transparent film layers is a mixture of polyvinylidene fluoride resin and ethylene-tetrafluoroethylene copolymer, and the electric qualitative change layer is arranged between the two transparent film layers. The sports training hall adopts conventional buildings, and this adjustable transparency film is used instead of sunshade accessories such as sunshade curtains in the sports training hall, and the adjustable transparency film is fixed by manual installation. When it is necessary to block the line of sight and light, The electric qualitative change layer is energized to change the transparency of the film with adjustable transparency, so as to isolate the line of sight and light.

[0037] In this embodiment 2, the membrane material replaces the auxiliary equipment such as sunshade curtains of conventional buildings, and can realize the conversion of space functions according to actual needs, and the pu...

Abstract

The invention relates to the field of constructional engineering, in particular to a film with adjustable transparency. The film with the adjustable transparency can replace glass or sunshade accessory equipment under the conventional construction condition to be applied to construction, achieve function conversion of inner space of a building and reduce investment, and is easy to install and operate. The defects of complex operation and large investment in the process of achieving function conversion of the inner space of the building by enlarging the accessory equipment under the conventional construction condition in the prior art are overcome. The film with the adjustable transparency comprises three overlaid film layers, wherein the two film layers located on the outside are transparent film layers, the inner film layer is an electrochromic layer which is connected with a power source through a wire.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a film with adjustable transparency. Background technique [0002] Transparent film is a light-weight material with good light transmission performance, and has broad application prospects in the field of construction engineering. Compared with materials with light transmission properties such as glass, transparent films can also provide good natural lighting, and have the functions of sunshade and rain. At the same time, the materials used to make transparent films are also characterized by light weight and low cost. It is easy to install when applied in the field of construction engineering, and can reduce the construction cost. [0003] Under normal building conditions, the light transmission of the building is usually achieved by installing glass. In order to meet the transparency requirements of the same building in different occasions, the existing technology usuall...
