Abstract
The utility model provides high shielding effect information leakage prevent glass. The utility model is composed of glass, a metal wire net and a polycarbonate film. The utility model is characterized in that both sides of the metal wire net are respectively provided with one layer of polycarbonate film, wherein, the outer side of which is respectively stuck with one layer of glass, the metal wire net, the polycarbonate film and the layer of glass are heated and pressed to form a whole body. The high shielding effect information leakage prevent glass is suitable for a visual window of an electromagnetic shielding body, such as a computer electromagnetic shielding machinery room, a computer electromagnetic preventing machinery desk, a server electromagnetic preventing machinery cabinet, etc. The utility model can effectively prevent computer electromagnetic information from leaking, can prevent electromagnetic interference from the outside from influencing the normal work of a computer, and can prevent electromagnetic waves from damaging a human body. In a measuring method of 60 centimeters, when a frequency is equal to 14K, 200K, 450K, 930K, the shielding efficiency can respectively reach 24dB, 47dB, 94dB, 76dB, and the light transmittance can reach 60%.
Description
Technical field:
The utility model relates to a kind of compound glass, particularly relates to a kind of high shielding effect information leakage prevent glass.
Background technology:
The use of computer now is the various aspects of people's lives such as office, school, family deeply, and electromagenetic wave radiation has caused people's attention to the injury of human body.Though existing computer protecting screen also just shields to the display front on the market, the electromagnetic wave of its side and back surface radiation can't shield.This is unfavorable for healthy.Relate to special sectors such as military affairs, national defence in addition, need the electromagnetic information of computer not revealed, it is far from being enough that protection screen only is set.
Summary of the invention:
The purpose of this utility model provides a kind of high shielding effect information leakage prevent glass, be used to place computer electromagnetic shielding equipment visual windows, can stop electromagnetic wave to personal injury, effectively suppress the leakage of computer electromagnetic information and prevent outside forceful electric power magnetic harassing and wrecking, influence the computer operate as normal.
High shielding effect information leakage prevent glass provided by the utility model, it is made up of glass, woven wire, polycarbonate film, its structure is that one deck polycarbonate film is respectively arranged respectively in the woven wire both sides, and the polycarbonate film outside is pasted with one deck glass respectively, and the heating pressing is in aggregates.
Described woven wire shirt rim in the high shielding effect information leakage prevent glass, every limit size are wanted wide and are gone out corresponding glass edge along 10-50mm, and woven wire is the 200-400 order, and the woven wire mesh wire diameter is 0.01-0.05mm.
High shielding effect information leakage prevent glass provided by the utility model, be applicable to computer electromagnetic shielding machine room, computer electromagnetic protection machine table, the visual windows of electromagnetic shields such as server electromagnetic protection rack, can effectively suppress information leakage and anti-electromagnetic interference, good visual effect is arranged simultaneously, light transmittance reaches 60, visual sense is good, and picture and text are clear.
Description of drawings
The front view of Fig. 1 the utility model high shielding effect information leakage prevent glass
The side view of Fig. 2 the utility model high shielding effect information leakage prevent glass
Among the figure: 2 glass, 3 polycarbonate films, 4 woven wires of 1 woven wire shirt rim
The specific embodiment:
In conjunction with the accompanying drawings the utility model is further described.
The high shielding effect information leakage prevent glass that present embodiment provides, it is made up of glass 2, woven wire 4, polycarbonate film 3, its structure is in woven wire 4 both sides one deck polycarbonate film 3 to be arranged respectively respectively, 3 liang of outsides of polycarbonate film respectively have one deck glass 2 respectively, and the heating pressing is in aggregates.The wide corresponding glass 2 edge 20mm of going out are wanted in described woven wire shirt rim 1, every limit size, and described woven wire 4 is 250 orders, and woven wire 4 mesh wire diameters are 0.03mm.
High shielding effect information leakage prevent glass provided by the utility model, be applied to electromagnetic shielding equipment visual windows, it is wide to be suitable for frequency range, the requirement of foot GB BMB3-1999B level and national military standard GJBZZ20219-94B level, under 60 centimeters mensurations, when frequency was 14K, 200K, 450M, 930M, screen was imitated and is reached 24dB, 47dB, 94dB, 76dB respectively, can be used as a kind of high, visual good light-transmission type electromagnetic shielding medium of effect that shields.
