Model No.: Waveguide Seal0001
Radar Antenna Feeder System Waveguide Sealing Window, Radar Phase Shifter Polarizing Film with Fluorophlogopite
Ideal neutron reflection experiment background material ------ fluorine crystal mica flakes
The mosaic of molybdenite is less than 0.25 degrees, it can absorb multi-band light beam, and because it does not contain (OH) helium, it will not appear dark phenomenon in the neutron reflection experiment, and it has an absolute advantage compared with natural mica. It is an ideal neutron reflection experimental background material.
Has been applied to military radar (microwave section, millimeter wave band) high-performance high-frequency material - fluoride crystal Mica Sheet
The dielectric constant of the fluorite mica is: 4.3 ε, and the dielectric loss is (1 44)×10 −4 tgr. Because of its low dielectric loss, stable dielectric constant, non-aging, non-breakable, easy to debug. It was selected by China Electronics Technology Group Nanjing 14 for sealing window of radar antenna feeder system. The Haomi band (Ka band) replaces the import, reducing the cost by as much as 10 times. The microwave section (C-band, L-band) replaces low-performance materials such as natural mica and PTFE, which overcomes the problems of aging and deformation of PTFE, high dielectric loss of natural mica, and improves overall machine performance.
Selected by China Electronics Technology Group Xi'an 39th and other units for radar polarizer phase shifter. Instead of quartz glass, metal and other low-performance materials, it overcomes the problems of fragile quartz glass and difficult to adjust the metal.
Fluorocrystalline mica is suitable for high-frequency environments of high-end equipment.
Its chemical formula is KMg3(AlSi3O10)F2 and does not contain (OH) hydrazine. Its texture is very pure and its electrical properties are very good. The volume resistivity is 1015 to 1016 Ω•cm (approximately 1000 times higher than that of natural mica); the electric breakdown strength is 185 to 238 kV/mm, which is 10 times that of PTFE; and the dielectric constant is 5.6 ε. The dielectric loss is: (1 ~ 4) × 10-4 tgδ. Can work in the 1100°C environment for a long time. Its melting and crystallization temperature is 1375°C. Hot and cold change stability is also very good. The five Guangzhou Saibao Laboratories (National
Level Test Center) Tested at -40°C to 70°C for 10 cycles, all qualified.
Because of its high-frequency dielectric loss, low dielectric loss, stable dielectric constant, non-aging, non-breakable, and easy to debug. It is the first choice material for high-tech media.
In 2004, our company has just launched fluoride crystal mica (also known as Fluorphlogopite Mica, artificial mica), which was selected by the China Electronics Science and Technology Group Nanjing No. 14 Research Institute and other units for Radar Antenna Feeder System Sealing Window (media film), and has continued Used so far. The millimeter-wave band (Ka-band) replaces imports and the cost is reduced by a factor of 10. The microwave band (C-band, L-band) replaces low-performance materials such as natural mica and polytetrafluoroethylene, which overcomes the aging and deformation of PTFE. The loss of natural mica is high and the overall performance is improved.
Selected by China Electronics Technology Group Xi'an No. 39 Research Institute and other units for radar polarizer polarizers. Instead of quartz glass, metal and other low-performance materials, it overcomes the problems of fragile quartz glass and difficult to adjust the metal.
