Embodiment
A kind of transparent space absorber of the present invention is made up of sounding board 1, transparent microperforated panel (film) 2 and hanging piece 3.Transparent microperforated panel 2 and sounding board 1 are made by transparent material.Sounding board 1 plays the skeleton supporting role, constitutes microperforated panel (film) resonance sound-absorbing structure with transparent microperforated panel (film) 2 simultaneously.
By adjusting the structure of transparent microperforated panel (film) and transparent sounding board 1, obtain different cavity resonator structures: triangle resonator cavity, polygon resonator cavity, cylindrical cavity, semicircle resonator cavity, conical resonator cavity, triangular taper resonator cavity, rectangular pyramid shape resonator cavity etc. are multi-form, the corresponding transparent space absorber that the different structure form is arranged: rectangular configuration, ship shape structure, trapezium structure, wedge shape structure, cylindrical structural, semicircular structure, conical structure, triangular pyramidal structure, rectangular pyramid shape structure etc.Can be made into different size and multi-form transparent space absorber according to on-the-spot different situations, reach the width that increases sound sucting band or adapt to noise abatement under various different frequencies, the environment.
Wherein, the cavity depth of the thickness of the micropore size of transparent microperforated panel (film) 2, percentage of perforation, material and resonance sound-absorbing structure influences the acoustical absorption coefficient of microperforated panel resonance sound-absorbing structure; Microperforated panel is thin more, helps the absorbing high-frequency noise more; The aperture is more little, material is thick more, and absorption band is wide more; Percentage of perforation big (within the specific limits), cavity are more little, help the absorbing high-frequency noise; Cavity is dark more, material is thin more, helps absorbing low frequency noise more, and the absorption band broad.Therefore select the structure and the different cavity depths of the different thickness of transparent microperforated panel (film) 2, the number of plies, aperture, percentage of perforation, sounding board 1, just can control the absorption resonance peak of microperforated panel (film) resonance sound-absorbing structure, make transparent space absorber in wider frequency, obtain good acoustically effective.
The method for making of transparent space absorber of the present invention is characterized in that it may further comprise the steps:
1, processing sounding board.
The blanking of sounding board is finished on the CNC machining center:
The following available CNC shearing machine of sounding board material thickness 3mm shears, and thickness adopts the electric saw blanking greater than more than the 3mm.The attention blanking need be put suitably pre-allowance, and process needs protect sheet material, prevents that plate surface from scratching.
Fixing on the mould that designs in advance with shearing good PC plate, be warmed up to 133～142 ℃ of preheatings after, carry out hot-formingly, after cooling, obtain the sounding board of moulding.To protect plate surface in the time of processing, prevent surface tear.
2, process transparent microperforated panel (film).
The processing of transparent microperforated panel (film) is finished on numerical control device:
Configure punching parameters such as percentage of perforation, aperture, pitch-row, thickness of slab on request; On the supporting autoloader plane of numerical control punching machine (punching should make mould, anchor clamps in advance, towards pin) or multi-head numerical control Gao Su machine or multiple head laser tapping and plugging machine; And all have the hard place that contacts all will protect with flexible material with sheet material adding man-hour; Prevent to add and produce the plate surface scuffing man-hour; It is even to add man-hour cloth hole, and blind hole can not be arranged.
3, the oven dry of sounding board, transparent microperforated panel (film) is bonding again after handling and finishing in baking oven.
Sounding board and transparent microperforated panel (film) be bonded in specific drying in oven after carry out, baking temperature is controlled at 121 ℃ and removes moisture content, carries out bonding typing when reducing to 45 ℃ then, obtains needed cavity resonator structure.Also to protect in the time of processing, prevent surface tear the sheet material face.
4, the transparent space absorber moulding in airtight intensive ultraviolet lighting case after the typing.
Transparent space absorber after the bonding typing advances prefabricated hermetic type intensive ultraviolet lighting case, carries out the ultraviolet ray irradiation, and the wavelength of UV-lamp is 305nm, by the operation instruction requirement control time of uv glue.Uv glue is all curable no shadow glue of a kind of low concentration, the high grade of transparency, high rigidity, ultraviolet light or visible light, have easy to use, curing rate is fast, bonding strength is big, transmittance is high, do not see advantages such as any glue-line is bonding, handling safety.All need in the type-approval process its surface is protected.
Because transparent space absorber hangs in the air, sound wave can incide the suspended absorber surface from different perspectives, and its acoustically effective is attached on the rigid plane much better than identical sound absorber in fact.The micropore of transparent microperforated panel (film) itself has enough acoustic resistances, when sound wave incides the transparent space absorber surface, friction through the micropunch edge, acoustic energy is converted into heat energy and is consumed or is converted into energy of vibration along the transmission transfer of transparent microperforated panel (film) surface, thereby reduces reverberation time and sound pressure level.
Transparent space absorber of the present invention, mainly utilize the sound absorption of transparent microperforated panel (film) resonance sound-absorbing structure, need not use other acoustic absorbant, therefore can be used on other material or the unaccommodated place of structure, require the occasion of degree of purification height, transparent daylighting when handling as environment such as high temperature, humidity, corrosive gas, high velocity air or sound absorption.Its Theoretical Calculation and measured value simple in structure, sound absorption characteristics is very approaching simultaneously.
Transparent space absorber of the present invention, inside also can be according to the needs of finishing, and portion is provided with illuminating lamp and polychromy lamp within it.
