SAW foam wedge absorbing material
Product description:
The SAW foam cone-splitting absorbing material is suitable for the constricted darkroom, the side wall of the tapered darkroom, the side wall of the RCS radar scattering cross section test table, the canopy floor and other parts, directing the energy to the rear wall for absorption and reducing the scattering to the static area.
Surface treatment options:
Weather-resistant sheath foam pyramid saw-wp
Ordinary SAW foam split cone absorbing material cover waterproof cover, with excellent waterproof characteristics;At the same time with wear resistance, aging resistance;Suitable for outdoor and other harsh test environment.
Product description:
SAW foam cone-splitting absorbing material is made of high quality and high density polyurethane foam, which is processed by molding, impregnating, drying, surface treatment and other processes.
Electrical properties:
Polyurethane foam is a kind of material with the best absorbing effect in microwave wide band because of its small parameters, small surface reflection and bulk absorption.
Flame retardant:
It meets the requirements of NRL8093, gb8624-b2, din4102-b2, iso11925-2, UL94 and other standards.Oxygen index ≥28%;Operating temperature: -50℃~80℃, up to 100℃ in a short time;
The power capacity is 1KW/m, short 1.5kw /m.
Environmental protection:
Inorganic raw materials, non-toxic and odorless, no harmful gas release, strictly controlled from the source;The finished products meet the RoHS environmental requirements of the European Union;The finished product is halogen-free;The formaldehyde emission of finished products reached the standard of gb18580-2001e1.The air quality in the dark room meets the GB/ t18883-2002 limited standard.
Physical properties:
The impregnation is uniform and the absorbing components adhere firmly.Appearance color uniform and customizable color;High consistency of specifications, beautiful appearance, not hanging tip;Soft, strong mechanical extrusion resistance, resilient.
Application:
Construction of microwave anechoic chamber, absorbing screen, microwave anechoic chamber for various purposes;Materials of different types, heights and structures can be selected flexibly according to the shape, performance requirements and different parts of the anechoic chamber.According to the customer demand design performance optimization;Under specific circumstances, such as outdoor requirements, can choose the relevant surface treatment model.
The SAW foam coning absorbing material can increase in weight by approximately 25% compared to SA at the same height;At high frequencies, the ratio of the height of the material to the working wavelength is d/ >8.In parallel, the performance deteriorates by about 10dB.At large Angle oblique incidence, the scattering is smaller than SA.In the low frequency band, the performance is better than that of the same height SA, and the height is smaller than SA when the same performance is achieved.
SAW bubbles PiZhui absorbing materials with good flame retardant performance, product meet the U.S. navy lab report NRL8093 Ⅰ (1977) test, withstand voltage test Ⅱ difficult, the spread of flame and the experiment Ⅲ smoldering requirements, its high oxygen index, and through the fire simulation experiment, and lasting flame retardant effect.Operating temperature -50℃~80℃, short time 100℃~120℃.Power capacity 1KW/m, short 1.5KW/m.
SAW foam cone-absorbing materials have good environmental performance, all raw materials meet the requirements of environmental protection, the main chemical ingredients are non-toxic, at the same time, the unique advanced formula of inorganic flame retardant, no volatilization, no odor and no toxicity, long-term use of flame retardant performance is stable without decline.
The surface is usually light blue, but other colors can also be customized.The shape of the wedge is neat, beautiful and clean, flexible and flexible.
Through arch method (dual antenna power reflection method), space standing wave method and coaxial reflection method and other tests, and in the authority of the third party testing institutions for independent testing.
