Anechoic chamber/ semi anechoic chamber

We are recognized as one of the leading manufacturer, exporter and supplier of high quality Anechoic Chamber. The offered chamber is manufactured with the best grade raw material and advanced techniques under the surveillance of our dexterous professionals in line with set industry norms. Our provided chamber is extensively installed in laboratories, auditoriums and other similar places. Moreover, this chamber can be availed by our respected patrons from us t market leading prices.

Technical Scope:

Some of the applications are:

• Broadcasting, Post Production
• Language Laboratories
• calibration
• R& D
• Institution
• Audiometric Rooms

Technical Details:

• The ZXB pyramid absorbing material is a type of electric loss absorbers, and pyramid
• structure is applied to perfectly match radio waves.
• With vertical incidence its wave impedance gradually changes from 377Ω to 2Ω, avoiding reflection on the absorber's surface.
• For those radio waves entering into the absorbing material, with its good electrical
• conductivity, such absorbing material rapidly transforms the electromagnetic energy to
• Ohm energy, thus to attenuate the radio waves.
• Assume the reflectivity of absorber is R, when its thickness wavelength ratio t/λ=0.2, R=-14dB; when t/λ=1, R=-31dB; when t/λ=7,R=-50dB. For detail reflection loss relationship, please refer to the following figure. Absorbing properties,

In line with clients' diverse requirements across the country, we are offering an enormous range of Microwave Absorber. The provided absorber has excellent fire retardant property and is suitable for auditoriums, halls, institutions, etc. Our offered absorber is checked against several parameters of quality by our quality examiners to ensure its flawlessness. This absorber is highly acclaimed in the market owing to its diverse qualitative attributes. Besides, clients can avail this absorber from us at industry leading prices.

Other Details:

Such absorber has good fire-resistant performance, as it is made up of inorganic substances. Tested according to GB/T2406-93Plastic combustion performance test method, the oxygen index method, with oxygen index over 60%, it can meet the requirement of GB8624-1997Flammability of building materials classification method, it is B1 Flame retardant materials. It can withstand high-power irradiation. Under the microwave power irradiation of below 15kw/sqm, it won't take any cooling facilities. The testing of flame ignition & spread, conductance and Internal heat, it shows its performance is superior to the requirements of test I voltage-resistant, test II difficulty of flame ignition and propagation, test III flame-resistant test of Navy laboratory report NRL8093 (1977). Therefore, no matter the irradiation of strong lighting, strong current, flame and strong microwave, it won't bring combustion. It is absolute safety materials, and it can be used in microwave anechoic chambers,, without any fire worries. Adopting such absorber can greatly simplify the anti-fire system in the anechoic chambers. It has been passed the review of some anti-fire safety departments [5].
