Cell phone jammer blocks well without any loophole

Also, pay attention to the spacing should be appropriate to tighten the screws to prevent deformation and generation gap materials. 3) The minimum deformation. Liner must have sufficient deformation in order to provide shielding effectiveness. Deformation is too small, not only the shielding effectiveness is poor, and shielding effectiveness is very sensitive to pressure, resulting in instability in shielding effectiveness of the chassis. Conversely, too much deformation will cause permanent deformation and damage to the liner.LRZT-9.1HH cell phone jammer blocks well without any loophole. Therefore, the deformation of magnetic sealing gasket must be appropriate. 4) compression. External eliminated, gasket can not return to its original state, known as the permanent deformation. Different application requirements for compression is not the same. After installation of a place is no longer open, permanent deformation does not matter; on frequent open places, this indicator is very important. 5) The liner thickness. Electromagnetic gasket thickness must meet with the maximum gap at just the right amount of deformation. 6) electrochemical compatibility. Note that to make use of similar electrochemical properties of metal materials overlap each other. Make use of high electromotive force of the metal (Table 1, groups of high and rearward of the metal). The corrosion of metals is not easy. Ⅴ. Commonly used electromagnetic solenoid gasket sealing gasket are: 1) Metal mesh liner:LRZT-9.1HH cell phone jammer is low power consumption. This is the most commonly used magnetic sealing material, the structure of a metal wire, and hollow rubber core three. The shielding performance: low-frequency shielding effectiveness when higher; high frequency shielding effectiveness is low. Generally used in the 1GHz the following occasions. Lower the price of wire mesh gaskets, excessive compression is not easy to damage. One rectangular cross-section for the casting process or machined shell; round and with a circular cross-section used in the sheet metal wing shell. They can use conductive glue fixed, rivets or spot welding can also fixed.It is easy and convenient to use LRZT-9.1HH cell phone jammer. Wire mesh gasket does not provide pressure or air seal, it can not be used in a salt spray environment. In order to effectively shield the amount of compression should be in the original height of 15% to 30% range. Metal mesh screen with a rubber gasket cross-section core wire 36 liner is flexible and has excellent electrical conductivity of woven wire mesh and have better compression and deformation characteristics of the rubber core (neoprene sponge rubber, silicone sponge rubber, silicone solid rubber) combined product. Its external shape is also a variety to choose from. The mesh liner with a rubber core is mainly used in the equipment housing with a wide range of uneven seams, especially for doors and other low pressure and low compression, the occasion will be permanently deformed. When the network with two layers of woven liner is compressed to the original height of 75% for optimal interference shielding effect. LRZT-9.1HH cell phone jammer applies the fence blocking method to block signals.Core wire with a rubber gasket sections QIANZHENYU 37 shielded metal mesh liner and mesh liner with a rubber core roughly the same electromagnetic shielding effectiveness of magnetic field (100kHz) about 80dB; of the electric field (10MHz) of about 130dB; 1GHz plane wave of about 105dB, 10GHz about 95dB. 2) Conductive Rubber: usually used in electromagnetic shielding requirements also need to have a higher moisture sealing applications. Structure on the strip material and shape materials two. Strip material is divided into two kinds of hollow and solid core (see figure).
