Cell phone jammer is the necessary outcome of humanized management

Usually shield absorption loss can reach 100db orders of magnitude have been able to meet most of the screening requirements. The use of 10 mil (0.3MM) thick copper will be surrounded by a 6-sided room, line-side power supply set to introduce a high frequency filter to prevent high-frequency electromagnetic waves caused by leakage along the power line, the general availability of 100db magnitude absorption loss of the shielding effect, and then for the lighting, ventilation, windows, holes, metal network to shield (the smaller the more dense metal mesh, the mesh is generally used 1.5MM) for the best results. The intelligent management system of    cell phone jammer    can eliminate the negative effects caused by the mobile phone.The use of metal mesh shielding layer can only get 40 ~ 50db of shielding effects, such as to take a greater shielding effect, should be double or triple metal mesh shield, shield the power cord in addition to installing high-frequency filter, the also the installation of different low-pass filter cutoff frequency, while the indoor power line requires the use of shielded cabling. Theory can be proved, shielding material thickness increases, depth of penetration and absorption of radio wave attenuation is also large, but at high frequencies the skin effect due to current, hard thick shield does not make sense. Single plate thickness δ generally take 1.5 ~ 2MM, double the thickness of steel plate in the 0.6 ~ 1.0MM to δ. The intelligent management system of    cell phone jammer    can perform function of safety and protection.Sixth, the overall layout of the shielded room, screen room is usually rectangular, it can then be separated from the construction there must also be closely integrated with the construction blend, while the latter is more suitable, usually divided into the following categories: shielded room individually placed construction completed in the room, with no special construction connected, this form for small rooms, especially suitable for conversion to shield the engine room of the old house with the situation, there is not much in the construction alteration request, but the load floor to review, such as to meet the demand should be made non-metallic materials reinforcement. The disadvantage is that space utilization is low, the cost is higher.    cell phone jammer   can make sure that environment can be purified and secrecy leaking and crimes can be prevented. Shielded room with a variety of link building wall (such as support, backing, hanging column), which is closely related with the construction, suitable for medium-sized room, the advantage of expanding the utility room area.
Shielding attenuation according to the technical requirements that can be done single, you can also do double shield. Double shielded room to be welded in two layers of metal shield located between the 25 mm thick wooden keel. The intelligent management system of    cell phone jammer is the necessary outcome of humanized management.Welding, shielded room project needs attention: ☆ continuous welding, which requires a continuous weld compact, no cold solder joint, weld.
Shielded room is also building the wall around the wall, play a role in separating space, shielding provides a sound-absorbing panels, insulation and other functions, so that the engine room to reduce the total cost of this form apply to medium-sized room. Supervision burden of prison officers can be reduced by using the intelligent management system of    china cell phone jammer .Seven, shielded room structure according to the building and construction considerations conditions, technical requirements for shielding chamber can choose to: use a continuous welding method, the metal shield together into one complete hexahedral.
