Acquire the soundproof effect data of siding position；As siding be mounted on build a wall with bricks or alloy sheets on when, pass through decibel detector point
Not Ce Liang sound source and through the sound decibel after masonry walls or alloy sheets, the two, which is subtracted each other, can export masonry walls or alloy sheets
Soundproof effect；
Preferably, passing through frequency and/or soundproof effect under the various environment that the various sidings of acquisition are installed to establish big number
According to library.In large database concept, corresponding frequency and/or soundproof effect data may bring up by input environment parameter, make data
It obtains more simple and efficient.
Above-mentioned layering foam device is as shown in Figure 1, the capping 20 including cavity 10 and its both ends connection and back cover 30；Its
In：
10 side wall of the cavity is made of at least two pieces of heating boards；Each heating board, the hair for covering 20 and back cover 30
Hot temperature is controlled respectively by central control system.
Preferably, 10 side wall of the cavity is made of the first heating board 11 and the first heating board 12 being arranged below；Institute
The space for stating capping 20 and the formation of the first heating board 11 is the upper layer for being layered foam device, temperature T1；30 He of the back cover
The space that second heating board 12 is formed is the lower layer for being layered foam device, temperature T2；First heating board 11, second is sent out
Hot plate 12, capping 20 and back cover 30 are made of electrically conductive exothermic material, such as copper, iron and aluminium；First heating board 11, second
Heating board 12, capping 20 and back cover 30 control control heating temperature by central control system；Central control system is computer visitor
Family end or other intelligent operation clients.By being layered the foaming of foam device, make the hair of layering foam device the upper and lower
It is different to steep temperature, to the different layered structure of the pore size for the every aspect that foams out (as shown in Figure 2).
Further, 12 side wall of the heating board is equipped with cooling chamber 13；The cooling chamber 13 is connect with refrigerating plant 40.Drop
Warm chamber 13 is looped around on 12 side wall of heating board, and cooling chamber 13 is connect with 40 pipeline of refrigerating plant；Refrigerating plant 40 is controlled with center
System communication connects；Refrigerating plant 40 is to prepare thermantidote, including but not limited to air-conditioning；The cold air that refrigerating plant 40 is prepared
Entered in cooling chamber 13 by pipeline.When central control system controls temperature T2 sizes, central control system controls heating board
12 stop fever, and control refrigerating plant 40 and prepare cold air and be conducted in cooling chamber 13；By cold air come regulation heating plate
12 temperature, to carry out fast cooling adjusting to temperature T2.
The preparation method of heat preservation and soundproof PVC sidings provided by the invention is determined by the acquisition of environmental parameter, can make this
It is more targeted to invent the heat preservation and soundproof PVC sidings prepared；The heat preservation and soundproof PVC walls prepared by being layered foam device
Plate has layering porous structure, the pore size on every aspect different；It can be to different frequencies by being layered porous structure siding
The sound wave of rate is effectively completely cut off, to make siding provided by the invention have excellent soundproof effect.
Although more herein used the terms such as cavity, heating board, capping and back cover, use is not precluded
The possibility of other terms.The use of these items is only for more easily describe and explain the essence of the present invention；Them
Any one of the additional limitations is construed to all to disagree with spirit of that invention.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, it will be understood by those of ordinary skill in the art that：Its according to
So can with technical scheme described in the above embodiments is modified, either to which part or all technical features into
Row equivalent replacement；And these modifications or replacements, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
