Abstract
The utility model relates to an anti-radiating shielded screen on a kinescope. The utility model is characterized in that a screen or a transparent film is served as a carrier 1; the carrier 1 is provided with a lead alloy anti-radiating conductive sieve-shaped shield layer 2 plated by ions; 3 is an earth conductor communicating the shield layer 2 and zero potential (referring to the specification). The utility model uses the existing shield-plating technology. Compared with protecting screens of plate frame type and fabric type, the utility model has the advantages of simple manufacturing process, low cost, thinner plated shield, no overlapped lines of fabrics, high image brightness, joint to the screen, light weight, curved property, convenient carrying, operation and maintenance, etc.
Description
The utility model is a kinescope radiation proof membranous type barrier.
When TV, computer work, there are low frequency radiation, static to gather before the fluorescent screen and nuisances such as high light and reverberation.For reducing it to the particularly injury of eyesight of human body, the sixties successively have nylon, carbon fibre and alloy silk system sieve shape barrier to release so far.But dark excessively because of existing shading excessively to cause image, the big slim and frahile and defectives such as subject to damage and the inconvenient operation and maintenance of valency height of body, people fail to be widely used to the understanding deficiency of electronic pollution eventually in addition, cause the face of being injured and expand day by day.
The purpose of this utility model is that a kind of barrier that can overcome above-mentioned defective will be provided.
The purpose of this utility model is achieved in that the leaded alloy reticular membranes of method plating one deck such as using the vacuum ionic spraying plating on transparent film, and draws earth lead from its side.Utilize vacuum, electrostatic effect easily film and fluorescent screen to be fitted.Film and alloy film can weaken high light, reverberation and ray, and the electric charge on the nethike embrane then can in time disappear from ground connection.
The utility model is used prior art, and technology is simple, and cost is not high.The membranous type barrier packing of can curling, easy to carry and use.Being overlapping of silk screen and more can be slim because plating seal nethike embrane does not interweave, mesh shape and size especially can be random, can overcome silk screen and cause the dark and gloomy defective of image.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing is according to the kinescope radiation proof membranous type barrier front view that the utility model proposes.
Below in conjunction with description of drawings concrete structure of the present utility model and working condition.
The base material of kinescope radiation proof membranous type barrier is a transparent film 1, and the screen cloth shape rete 2 of the lead alloy material of ion plating under the vacuum condition is arranged on it, and it can shield ray, compile electric charge as woven wire.The 3rd, connect screen cloth shape rete 2 and zero potential, be used for disappearing and let out the earth lead of electric charge.
Plated film is an important document with radioresistance, conduction and ground connection, and shape is not limited to nettedly seek only interconnected the disappearing in order to electric charge of dotted line and let out, that is can be entire body plating and can not be nebulous and parallel lines.The plating material can be inhaled apolegamys such as ripple thing lead, sodium, carbon, silicon, ferrite, omphacite from high loss.Film forming also is not limited to spraying plating, also the radioresistance conductive fine powder can be sneaked into plastics and be directly formed to the radiation proof diaphragm.The kinescope factory then can be directly at fluorescent screen coating surface radioresistance conducting film.
Claims (3)
1. kinescope radiation proof membranous type barrier is characterized in that base material is a transparent film 1, and the screen cloth shape rete 2,3rd of the lead alloy material of ion plating under the vacuum condition is arranged on it, connects the lead of screen cloth shape rete 2 and zero potential.
2. kinescope radiation proof membranous type barrier according to claim 1 is characterized in that base material also can be exactly the picture tube fluorescent screen, and lead alloy rete 2 can not be netted also but entire body is plated to.
3. kinescope radiation proof membranous type barrier according to claim 1 is characterized in that also the radioresistance conductive fine powder can be sneaked into plastics is directly formed to the radiation proof diaphragm.
