Detailed description of the invention
In order to understand the present invention better, illustrate content of the present invention further below in conjunction with embodiment, but content of the present invention is not only confined to the following examples.
Embodiment 1
Radiation proof acoustical board as shown in Figure 1 and Figure 2, the wire gauze 2 comprising two-layer first polyester fiber board 1 and be compounded between two-layer first polyester fiber board 1.Two-layer first polyester fiber plate thickness is equal; The thick 0.2mm of wire gauze, mesh wire diameter 0.2mm, mesh shape is rhombus, mesh-density 20 orders/inch; Acoustical board surface is also compounded with the second polyester fiber board 3 of sinusoidal wave structure, and it is 7mm that described second polyester fiber board 3 comprises the thick of sinusoidal wave.Sinusoidal wave wave bottom width is 80mm, and the percentage that on the second polyester fiber board, 3 all sinusoidal wave wave bottom width sums account for the second polyester fiber board 3 length is 40%; It is 15mm that acoustical board comprises the thick of sinusoidal wave on the second polyester fiber board 3.
Embodiment 2
Radiation proof acoustical board as shown in Figure 1 and Figure 2, the aluminum fiber net 2 comprising two-layer first polyester fiber board 1 and be compounded between two-layer first polyester fiber board 1.Two-layer first polyester fiber board 1 thickness is equal; The thick 0.8mm of aluminum fiber net, surface density 1.7kg/m
2, mesh wire diameter 0.2mm, mesh shape is rhombus, mesh-density 12 orders/inch; Acoustical board surface is also compounded with the second polyester fiber board 3 of sinusoidal wave structure, and it is 8mm that described second polyester fiber board 3 comprises the thick of sinusoidal wave.Sinusoidal wave wave bottom width is 100mm, and the percentage that on the second polyester fiber board 3, all sinusoidal wave wave bottom width sums account for the second polyester fiber board 3 length is 60%; It is 25mm that acoustical board comprises the thick of sinusoidal wave on the second polyester fiber board 3.
The preparation method of embodiment 1,2 radiation proof acoustical board is: wire lath is preheated to 214 DEG C, is placed between two piece of first polyester fiber board, and pressurize 0.1 standard atmospheric pressure, keeps 10 seconds, obtain radiation proof acoustical board.
By chip detecting equipment, be placed in area and be about 10m
2instrument in, due between instrument with device channels only a wall every the sound insulation of, original wall body not, cause room noise and electric field, environmental requirement that magnetic field intensity all can not meet apparatus installation.
Owing to relating to noise reduction and radiation-resistant requirement, employ above-mentioned radiation proof acoustical board in room transformation, be specially:
1. inner wall surface Installation of New Type compound radiation proof acoustical board between device channels periphery wall and instrument, because space in device channels is originally little, in order to conserve space, wherein the NEW TYPE OF COMPOSITE radiation proof acoustical board of device channels adopts subsides wall method (and chamber of not leaving a blank between former metope) to construct, and acoustical board thickness is 25mm.Inner wall surface acoustical board thickness 15mm between instrument, and cavity 30mm between body of wall.
2. because existing equipment corridor and instrument standoff wall sound insulation factor are inadequate, for increasing sound insulation further, the body of wall that is connected with device channels between instrument installs 5mm gypsum plank additional, gypsum plank adopts keel connect radiation proof acoustical board that pavement thickness is 15mm, cavity 30mm after plate.
3. before and after transforming, noise monitoring has been carried out about the detection requirement of room noise by " standard for acoustic environmental quality " (GB3096-2008), monitoring result shows, after improvement project completion, between instrument, room noise A sound level reduces about 7 ~ 8dB (A), C sound level reduces 5 ~ 6dB (C), meet producer require not higher than the requirement of 60dB (C).Before and after transformation, indoor electromagnetic radiation level monitoring between instrument has been carried out by " electromagnetic radiation protection regulation " (GB8702-1988) requirement, monitoring result shows, after improvement project completion, indoor average field intensity, magnetic field intensity reduces about 96% before comparatively transforming, (namely as thought that indoor electric magnetic field causes by external environment, then the radiation-resistant glass value of whole engineering is about 14dB, owing to still having door and window, ceiling etc. transformations, so the radiation-resistant glass value of 20dB can not be reached), after transformation, indoor environment meets the requirement of apparatus installation.
