Problems solved by technology

Although there are computer protective screens on the market, they only protect the front of the monitor, but the electromagnetic waves radiated from the side and the back cannot be shielded.
it's not good for your health
There are also special departments involving the military, national defense, etc., which require the electromagnetic information of the computer not to be leaked. It is far from enough to only set up a protective screen.

Embodiment Construction

[0010] The present invention will be further described in conjunction with the accompanying drawings.

[0011] The high-efficiency anti-information leakage glass provided in this embodiment is composed of glass 2, wire mesh 4, and polycarbonate film 3, and its structure is that there is a layer of polycarbonate film 3 on both sides of the wire mesh 4. , the two outer sides of the polycarbonate film 3 respectively have a layer of glass 2, heated and pressed into a whole. The size of each side of the wire mesh skirt 1 should be 20mm wider than the edge of the corresponding glass 2, the wire mesh 4 is 250 mesh, and the wire diameter of the wire mesh 4 is 0.03mm.

[0012] The high-efficiency anti-information leakage glass provided by the present invention is applied to the visible window of electromagnetic shielding equipment, has a wide frequency band, and meets the requirements of the national standard BMB3-1999B level and the national military standard GJBZz20219-94B level. Und...

Abstract

The invention discloses a glass for prevention of information leakage which comprises glass, metal mesh and polycarbonate film, wherein two layers of polycarbonate films are arranged on each side of the metal mesh, a layer of glass is adhered on the outboard of the polycarbonate film by thermal compression bonding to form a unitary. The invention can effectively prevent information leakage, and diminishes the possible injury by the electromagnetic wave to the human body. íí

Description

Technical field: [0001] The invention relates to a composite glass, in particular to a high screen efficiency anti-information leakage glass. Background technique: [0002] Now the use of computers has penetrated into all aspects of people's lives such as institutions, schools, and families, and the harm of electromagnetic wave radiation to the human body has attracted people's attention. Although there is a computer protective screen on the market, it only protects the front of the display, but the electromagnetic waves radiated from its side and back cannot be shielded. This is bad for your health. There are also special departments involving the military, national defense, etc., which require the electromagnetic information of the computer not to be leaked, and it is far from enough to only install a protective screen. Invention content: [0003] The purpose of the present invention is to provide a high-efficiency anti-information leakage glass, which is used to place...
