The low frequency adsorbed film is the structure of the miscellaneous periodical metal wire of mask plastic clip after drying；
The protective film is opaque.
The above-mentioned wall construction for the detection of product electromagnetic performance, the multilayer that the wall is glass, tinfoil is cross-linked
Structure, outermost layer and innermost layer are glassy layer.
The above-mentioned wall construction for the detection of product electromagnetic performance, the week of metal wire in high frequency adsorbed film and low frequency adsorbed film
It is with carbon protective film.
The above-mentioned wall construction for the detection of product electromagnetic performance, the protective film are sandwiched between carbon dust layer for two sheet glass
Structure.
The above-mentioned wall construction for the detection of product electromagnetic performance, the figure of metal wire is circle in the low frequency adsorbed film
Shape, rectangular, rectangle or diamond structure.
Advantageous effect：
Firstth, since wall construction of the present invention for the detection of product electromagnetic performance includes wall, high frequency adsorbed film, low frequency
Adsorbed film and protective film, and high frequency adsorbed film and low frequency adsorbed film are the structure of the miscellaneous metal wire of mask plastic clip after drying, thoroughly
Overturn the division between traditional screened room and absorbing material, so overturn screened room and absorbing material discrete design, ferrite and
The traditional design mode of sponge absorber discrete design, therefore can realize the thickness for reducing wall；
Secondth, due in wall construction of the present invention for the detection of product electromagnetic performance, finding periodical metal wire structure
Have the function of to adsorb low-frequency electromagnetic wave, and ferrite is replaced using the miscellaneous periodical metal wire structure of mask plastic clip after drying, because
This can reduce wall mass；
In third, the wall construction detected due to the present invention for product electromagnetic performance, aperiodic metal wire structure is found
Have the function of to adsorb frequency electromagnetic waves, and absorb instead of sponge using the miscellaneous aperiodic metal wire structure of mask plastic clip after drying
Body replaces pyramidal structure, therefore can reduce cost of manufacture using planar structure, reduces wall thickness；
4th, since in wall construction of the present invention for the detection of product electromagnetic performance, wall weight and thickness subtract simultaneously
It is small, therefore installation procedure can also be simplified.
Description of the drawings
Fig. 1 is structure diagram of the present invention for the wall construction specific embodiment one of product electromagnetic performance detection.
Fig. 2 is structure diagram of the present invention for the wall construction specific embodiment two of product electromagnetic performance detection.
In figure：1 wall, 2 high frequency adsorbed films, 3 low frequency adsorbed films, 4 protective films.
Specific embodiment
The specific embodiment of the invention is described in further detail below in conjunction with the accompanying drawings.
Specific embodiment one
The wall construction for the detection of product electromagnetic performance of the present embodiment, structure diagram are as shown in Figure 1.The wall knot
Structure from outside to inside, includes successively：
Wall 1, high frequency adsorbed film 2, low frequency adsorbed film 3 and protective film 4；
The wall 1 is opaque；
The high frequency adsorbed film 2 is the structure of the miscellaneous aperiodic metal wire of mask plastic clip after drying；
The low frequency adsorbed film 3 is the structure of the miscellaneous periodical metal wire of mask plastic clip after drying；
The protective film 4 is opaque.
Specific embodiment two
The wall construction for the detection of product electromagnetic performance of the present embodiment, structure diagram are as shown in Figure 2.The wall knot
Structure from outside to inside, includes successively：
Wall 1, low frequency adsorbed film 3, high frequency adsorbed film 2 and protective film 4；
The wall 1 is opaque；
