Description
Technical field
The utility model relates to building decoration technology field, particularly a kind of acoustics decoration panel possessing electromagnetic radiation shielding function.
Background technology
Contamination of Electromagnetic Wave refers to natural and artificial various electromagnetic interference and the dirt of harmful electromagnetism spoke, the modern large-scale cultural building of arenas, music hall, conference hall etc., be unable to do without all kinds of electric equipment, the electric equipments such as heavy-duty motor, transformer and power transmission line, the electromagnetic field that these electric equipments produce, can produce harsh electromagnetic interference in near-field region, due to the development of broadcast, TV, microwave technology, radio-frequency apparatus power is multiplied, wide frequency range, and influence area is also larger.Ground electromagnetic radiation increases considerably, and the mutual change of Electric and magnetic fields generates electromagnetic waves, and electromagnetic wave, to air-launched or the phenomenon of flood of converging, is called electromagenetic wave radiation (or electromagnetic radiation).Excessive electromagenetic wave radiation just causes the principal element that electromagnetic wave dirt, particularly RF electromagnetic radiation have become Contamination of Electromagnetic Wave environment.
Along with the development of material and cultural life and present information science and technology, everyone at least has a mobile phone at present, answers various information at any time.Viewing and admiring in musical drama performance process; spectators also often can receive calls; the spectators (even the music such as commander performance personnel) being faced to seat week are brought great noise jamming by the sound received calls, the tinkle of bells of mobile phone etc., and the transformer station in theater, music hall, electric equipment etc. can produce stronger electromagnetic radiation and noise jamming.Musical drama, concert are in performance process, spectators and the music such as commander, pianist performance personnel need quiet acoustic environment, and these interference, performing effect will be had a strong impact on, even may cause stopping playing of the music such as commander, pianist performance personnel, also cause being discontented with of spectators and audience.
Therefore each functional space retaining wall such as theater, music hall, studio, auditorium needs enough oise insulation factors to avoid the noise jamming of different spaces.Need ELECTROMAGNETIC RADIATION SHIELDING, to avoid from various electromagnetic interference.In order to prevent and suppress Electromagnetic Interference, shield technology is the basic means suppressing electromagenetic wave radiation.One of them free-revving engine of shielding is limited in specific region emittance, or prevent emittance from entering another specific region.Shielding material is the key of shield effectiveness height.
And in actual cultural building work progress, each functional space generally adopts light-weight brick body of wall interval, as air entrained concrete brick wall body etc., even adopt hollow type light-weight brick body of wall.This will have a strong impact on the indoor noise environment of each functional space, far can not meet the good sound insulation property required for functional space such as theater, music hall, auditorium, studio and ELECTROMAGNETIC RADIATION SHIELDING function.Good performing effect can not be ensured.
Therefore, prior art has yet to be improved and developed.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel acoustics decoration panel possessing electromagnetic radiation shielding function, and the building enclosure body of wall that solve the functional spaces such as theater, music hall, auditorium, studio possesses the problem of good sound insulation property and ELECTROMAGNETIC RADIATION SHIELDING function.Avoid the tinkle of bells of spectators' mobile phone, receive calls etc. sound noise jamming that the spectators at periphery seat music performance personnel such as (even) commanders are brought; The stronger electromagnetic radiation avoiding transformer station, electric equipment etc. to produce and noise jamming.Thus ensure theater, music hall required quiet acoustic environment in performance process, meet the enough oise insulation factors of each functional space retaining wall needs such as studio, auditorium to avoid the requirement of the noise jamming of different spaces.
To achieve these goals, the utility model provides following technical scheme:
Possess an acoustics decoration panel for electromagnetic radiation shielding function, wherein, comprising: a kind of high density bottom sheet material be made up of raw material such as AlSiO3 fiber, GRG powder being positioned at bottom; Also comprise the middle sheet material of a kind of expanded metal be positioned on bottom; Also be included in the hydraulicity composite faces sheet material that the raw material such as alkali resistant glass fiber, low alkalinity cement is made up of different from bottom panel density and hardness on sheet material in the middle of expanded metal.
Described bottom sheet material by AlSiO3 fiber, high strength that GRG powder raw material form, high rigidity and the hydraulicity composite faces sheet material be made up of the raw material such as alkali containing glass fibre, low alkalinity cement, change into production drawing according to the drawing of engineering project, determine every size, carry out mould, then the mode of production of fluid precasting is used, first at mould upper.In process, after the cast of bottom sheet material, put into that particular adhesive is crossed in overall dip-coating, that size is suitable expanded metal on bottom sheet material upper berth, expanded metal is poured into a mould the material of surface layer sheet again, after three kinds of sheet material cast laies, through shaking closely knit process, then heating cure sizing.
Adopt the utility model to possess the acoustics decoration panel of electromagnetic radiation shielding function, owing to adopting the board of two kinds of high density material combinations of different-thickness, according to building element mass law of sound insulation, surface density is larger, and oise insulation factor is larger.Because the sheet material of wherein two kinds of different surface densities exists different resonant frequencies, can avoid causing sound insulation sharply to decline due to frequency resonance.Because coincidence effect is not only relevant with the density of material, also relevant with the condition such as modulus of elasticity, thickness, Poisson's ratio of material.Therefore adopt the material of two kinds of different physical characteristics of different-thickness, make the physical parameters such as the density of this new material, modulus of elasticity, thickness, Poisson's ratio have notable difference, thus this new material coincidence effect is died down, thus improve oise insulation factor.
There is an expanded metal due in the middle of bottom sheet material and surface layer sheet, porous metals plate earthing altogether, so electromagnetic wave is received by expanded metal and is sensed as electric current and imports underground, thus shield electromagnetic width and penetrate.By on-the-spot test, all kinds of mobile phone all can not receive communication signal.
Calculate through oise insulation factor, the thick acoustics decoration panel possessing electromagnetic radiation shielding function of 17mm is about 52dB in the oise insulation factor of 500Hz frequency range.And can extrapolate, the thick oise insulation factor possessing the acoustics decoration panel of electromagnetic radiation shielding function of 17mm is equivalent to the oise insulation factor of 4 pieces of thick common paper surface gypsum boards of 12mm.
Possess the acoustics decoration panel of electromagnetic radiation shielding function, the building enclosure body of wall of the functional space such as theater, music hall, auditorium, studio can not only be made to possess ELECTROMAGNETIC RADIATION SHIELDING function.The enough oise insulation factors of each functional space retaining wall needs such as studio, auditorium can also be met to avoid the requirement of the noise jamming of different spaces.
