Description

Technical Field

[0001] The utility model relates to the technical field of wave-absorbing materials, in particular to a high-sized microwave darkroom corridor wave-absorbing structure. Background Art

[0002] Absorbent materials are placed in the corridors of large microwave anechoic chambers. Absorbent materials are materials that absorb or significantly attenuate electromagnetic energy received by their surfaces, thereby reducing electromagnetic interference. Absorbent materials in microwave anechoic chamber corridors must meet various requirements, such as load-bearing capacity and energy absorption, to ensure the overall performance of the microwave anechoic chamber. Furthermore, they are generally larger in size.

[0003] Currently, polyurethane sponge absorbing materials are commonly used in wooden boxes as microwave darkroom walkway absorbing materials. Although the current microwave darkroom absorbing materials have sufficient load-bearing capacity, their wave absorption and energy absorption are greatly affected by the wooden boxes; other soft walkway absorbing materials are not load-bearing enough.

[0004] There are other microwave darkroom absorbing materials that are split into integral shapes, and the height will be limited. Generally, they can only be made into 200-300 mm high aisle absorbing materials. For the higher-sized 500 mm high aisle absorbing materials, the shaping will be restricted. Utility Model Content

[0005] The utility model mainly solves the technical problems that polyurethane sponge absorbing materials are currently commonly used in wooden boxes as microwave darkroom walkway absorbing materials, but the wave absorption and energy absorption are greatly affected by the wooden boxes, and other microwave darkroom absorbing materials are split into integral shapes, which will limit the height. A high-sized microwave darkroom walkway absorbing structure is proposed, which is a relatively high-sized walkway absorbing material with both load-bearing and absorption properties.

[0006] The utility model provides a high-size microwave darkroom walkway absorbing structure, comprising: a bottom layer, an absorbing layer, a filling layer and a top layer arranged in sequence from bottom to top;

[0007] The bottom layer is a polypropylene flat plate absorbing material, and a plurality of grooves are provided on the bottom layer;

[0008] The absorbing layer is made of polypropylene absorbing material; the absorbing layer adopts a plurality of pyramidal structures, and the bottom of each pyramidal structure is inserted into the groove of the bottom layer;

[0009] The filling layer is a polypropylene split-type material, and the top layer is a polypropylene flat plate material.

[0010] Preferably, the overall height of the bottom layer, the absorbing layer, the filling layer and the top layer is greater than 500 mm.

[0011] Preferably, the filling layer is inserted into the absorbing layer.

[0012] Preferably, the filling layer and the top layer are made of white polypropylene material.

[0013] Preferably, the filling layer and the top layer are fixedly connected.

[0014] Preferably, the plurality of pyramidal structures are distributed in a matrix pattern on the bottom layer.

[0015] Preferably, the top of the pyramidal structure is ridged or pointed;

[0016] The shape of the filling layer is adapted to the shapes of the multiple pyramid-shaped structures.

[0017] Preferably, when the top of the pyramidal structure adopts a corrugated shape, the transverse corrugated pyramidal structures and the longitudinal corrugated pyramidal structures are staggered.

[0018] The utility model provides a high-sized microwave darkroom walkway absorbing structure, in which the bottom layer and the absorbing layer are made of polypropylene material, and polypropylene has excellent mechanical and electrical properties. The bottom layer with absorbing properties and the pyramidal structure absorbing material absorb electromagnetic waves and ensure the absorbing performance; the polypropylene split-type and pyramidal structures without absorbing properties inserted in the middle are matched, and then combined with the top layer of polypropylene flat material to form a whole, which plays a supporting role and ensures the load-bearing capacity. The polypropylene flat bottom layer and the polypropylene absorbing layer are formed separately, which can make the pyramidal structure larger in size and can produce high-sized products. Inserting the pyramidal structure into the bottom layer can ensure that the two fit closely and increase the load-bearing capacity. The high-sized microwave darkroom walkway absorbing structure of the utility model is a higher-sized walkway absorbing material with both load-bearing and absorbing properties, and can be widely used in the paving of microwave darkroom walkways.

[0022] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, rather than all of its contents.

[0023] like Figure 1-3 As shown, an embodiment of the present invention provides a high-sized microwave darkroom walkway absorbing structure, comprising: a bottom layer 1, an absorbing layer 2, a filling layer 3 and a top layer 4 arranged in sequence from bottom to top.

[0024] The bottom layer 1 is a polypropylene flat plate absorbing material, and a plurality of grooves are provided on the bottom layer 1;

[0025] The absorbing layer 2 is made of polypropylene absorbing material; the absorbing layer 2 adopts a plurality of pyramidal structures, and the bottom of each pyramidal structure is inserted into the groove of the bottom layer 1;

[0026] The filling layer 3 is a polypropylene split material, and the filling layer 3 is inserted into the absorbing layer 2 .

[0027] The top layer 4 is made of a polypropylene flat plate material. Specifically, the filling layer 3 and the top layer 4 are made of white polypropylene material. The filling layer 3 and the top layer 4 are fixedly connected.

[0028] The overall height of the bottom layer 1, the absorbing layer 2, the filling layer 3 and the top layer 4 is greater than 500 mm.

[0029] On the basis of the above scheme, multiple pyramidal structures are distributed in a matrix on the bottom layer 1. The top of the pyramidal structure adopts a corrugated or pointed shape; the shape of the filling layer 3 is adapted to the shape of the multiple pyramidal structures. When the top of the pyramidal structure adopts a corrugated shape, the horizontal corrugated pyramidal structures and the vertical corrugated pyramidal structures are staggered (such as Figure 2 shown).

[0030] A non-absorbing white polypropylene split material (filling layer 3) is inserted into the gaps within the polypropylene absorbing material's pyramidal structure (absorbing layer 2), forming a tight fit and providing support. The top layer 4, a non-absorbing white polypropylene flat plate, evenly distributes force between the filling layer 3 (split polypropylene) and the absorbing layer 2 (pyramid structure), forming the walkway board into a single unit and increasing its load-bearing capacity.

[0031] The utility model relates to a high-sized microwave darkroom walkway absorbing structure, wherein the bottom layer 1 and the absorbing layer 2 are made of polypropylene, which has excellent mechanical and electrical properties. The bottommost absorbing layer 1 and the pyramidal absorbing material absorb electromagnetic waves, ensuring the absorbing performance. The non-absorbing polypropylene split-type and pyramidal structures inserted in the middle are matched, and together with the top 4 polypropylene flat plate materials, they form a whole, play a supporting role, and ensure the load-bearing capacity. The polypropylene flat plate bottom layer 1 and the polypropylene absorbing layer 2 are formed separately, which can make the pyramidal structure larger in size and can produce high-sized products. Inserting the pyramidal structure into the bottom layer 1 can ensure a close fit between the two and increase the load-bearing capacity. The utility model relates to a high-sized microwave darkroom walkway absorbing structure, which is a high-sized walkway absorbing material with both load-bearing and absorbing performance.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications to the technical solutions described in the above embodiments, or equivalent replacement of some or all of the technical features therein, do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
