Izinhlobo ezijwayelekile zokuthiba umsindo

Ngokusho kokuhlukaniswa kwezinto zokwakha, isithiyo somsindo singahlukaniswa ngezigaba ezilandelayo: isithiyo somsindo wensimbi (izivalo zensimbi, igwebu le-aluminium), isithiyo somsindo kakhonkolo (ukhonkolo ongasindi, ukhonkolo onamandla aphezulu), umgoqo womsindo we-PC, umgoqo womsindo we-FRP, njll.

Uma kuqhathaniswa nezinye izinto ezivamile zokumunca umsindo, ezifana noboya bengilazi kanye ne-asbestos, i-aluminium Foam inezici zokuzisekela, ukumelana nokushisa okuphezulu, akukho ukukhululwa kwamagesi ayingozi, ukumuncwa komswakama ophansi kanye nokumelana nesimo sezulu esihle. Inamandla amakhulu. Isizukulwane esisha sezinto ezimunca umsindo. Ngakho-ke, isetshenziswa kabanzi emkhakheni wokunciphisa umsindo wethrafikhi kanye nobunjiniyela bokuvikela imvelo, njengokukhiqizwa kwezithiyo zomsindo ezisebenza kahle kakhulu, izindonga ezibamba umsindo, njll.

Izinzuzo ze-aluminium foam sound barrier

Igwebu le-aluminium lakhiwa ngokwengeza izithasiselo ku-aluminium ehlanzekile noma ingxubevange ye-aluminiyamu bese kwenziwa inqubo yokwenza amagwebu. Ngesikhathi esifanayo, inezici zensimbi nama-bubbles. Iwuhlobo olusha lwempahla emunca umsindo enezimbotshana.

Izinzuzo zezithiyo zomsindo we-aluminium foam ikakhulukazi zihlanganisa izici ezilandelayo:

1. Ukusebenza okuhle kakhulu kokumunca umsindo

Isithiyo somsindo wegwebu le-aluminium sinokusebenza kokumunca komsindo okuzinzile, isilinganiso se-coefficient yokumuncwa sikhulu kuno-0.64, futhi i-coefficient yokunciphisa umsindo imayelana ne-NRC0.75. Emvuleni noma ngemva kokumunca uthuli, i-coefficient yokumunca umsindo ngeke ishintshe, ehlangabezana nezidingo ze-acoustic zemingcele yomsindo womgwaqo.

2. Kulula ukufaka

Isithiyo somsindo we-aluminium foam senziwe nge-aluminium ehlanzekile, futhi ibhodi le-aluminium foam elibamba umsindo lingavezwa ngokuqondile emkhathini, ngaphandle kwesidingo sesendlalelo somswakama-umswakama, ungqimba oluphikisana nokugqwala kanye nokugcwalisa, njll., futhi kulula, futhi kulula. ukufaka.

3. Kulula ukuyigcina nempilo ende

Amaphaneli amunca umsindo we-aluminium Foam ayasheka njengengilazi, futhi angazihlanza ngokwawo emvuleni yemvelo. Noma ngabe uthuli lunqwabelana, ngeke kuthinte kabi ukusebenza kwalo kwe-acoustic, kodwa luzothuthukisa ukusebenza kokumuncwa komsindo wemvamisa ephezulu. Ngesikhathi esifanayo, inokumelana nesimo sezulu esihle, ukumelana nokugqwala nokumelana nokuguga, futhi impilo yesevisi ingafinyelela eminyakeni engaphezu kwengu-30.

4. Ukubukeka ngokwezifiso, ukuvikelwa okuluhlaza kanye nemvelo

Ingaphezulu legwebu le-aluminium lingafuthwa nge-fluorocarbon, futhi umbala ungenziwa ngokwezifiso ngokuya ngezidingo zomsebenzisi; igwebu le-aluminium alikwazi ukusha, eliluhlaza okotshani futhi alingcolisi, futhi ngeke likhiphe izinto eziyingozi emazingeni okushisa aphezulu, futhi lingagaywa kabusha ngokuphelele futhi lisetshenziswe kabusha.

Isakhiwo esivamile sesithiyo somsindo we-aluminium foam

1. "iphaneli ye-aluminium Foam emunca umsindo + iphaneli yensimbi yangemuva"

Ibhodi le-aluminium eliyinhlanganisela ye-foam elihlanganisa umsindo lisetshenziswa ngokuqondile njengephaneli (i-breaking load> 1000N, indawo engaphezulu ingathwala umthwalo we-1500N/m2; ukuphambuka 0.089

2. “Iphaneli ye-aluminium enembobo eboshiwe + iphaneli emunca umsindo yegwebu le-aluminium + iphaneli yensimbi yasemuva”

Ibhodi eliyinhlanganisela ye-aluminium foam lisetshenziswa njengesendlalelo sesangweji esiphakathi, ngakho-ke igwebu le-aluminium lingaba ubukhulu obuyi-5mm-7mm, obungenawo umthelela kumthamo wokumunca umsindo futhi lehlise izindleko; ibhodi le-aluminium eliyinhlanganisela yegwebu elimunca umsindo line-coefficient yokumunca umsindo engu-0.75, engahlangabezana nezidingo zama-viaducts asemadolobheni ebangeni elingu-200-4000Hz I-coefficient yokumunca umsindo edingwa yizinga lokuvimbela umsindo lingakha imbobo ezwakalayo ecishe ibe ngu-50mm, okuthuthukisa ngokwengeziwe umphumela wokumunca womsindo cishe ngo-3dB.

3. “Iphaneli + umzimba oyinhlanganisela omunca umsindo (igwebu le-aluminum + nezinye izinto ezimunca umsindo) + iphaneli yangemuva yesikhala”

Uma kubhekwa iqiniso lokuthi ukuqina kwephaneli ye-aluminium Foam emunca umsindo, kuba ngcono amandla nomsindo wokuvala umsindo, kodwa imizimba emunca umsindo ephezulu nephansi idlala indima yokumunca umsindo. I-Yante Material Technology (Luoyang) Co., Ltd. ingakwazi ukusebenzisa umklamo okhethekile we-backboard cavity yamaphaneli abamba umsindo + amaphaneli amancane e-aluminium foam nezinye izinto ezimunca umsindo ukuze zakhe imizimba emunca umsindo + izakhiwo zamaphaneli amafomu ahlukene noma izinto zokwakha ngokusho izidingo zangempela zabasebenzisi, ukuhlinzeka abasebenzisi ngohlelo oluhlosiwe lwephaneli yephaneli yokumunca umsindo wocansi.

Isithiyo somsindo we-aluminium foam

I-coefficient yokumuncwa komsindo yebhodi elingenalutho legwebu le-aluminium ingaphezulu kuka-0.45, futhi i-coefficient yokumunca umsindo ingafinyelela ngaphezu kuka-0.75 ngemva kokubhobozwa nokucindezelwa.

Inokumelana nesimo sezulu esihle futhi ingasetshenziswa kakhulu emigwaqweni, ezitimeleni nasezindleleni zikamasipala zasemadolobheni.

Ngaphezu kwalokho, izithiyo zomsindo we-aluminium foam zingasetshenziselwa izindonga eziqondile ngaphansi konqenqema lwesiteji seziteshi zesitimela esingaphansi nezindonga ezihambisanayo zomhubhe, izinhlangothi ezingaphezulu nezimbili zemigudu yesiteshi, amagumbi okuphatha esiteshini kanye nemishini, imibhoshongo yokupholisa phansi esiteshini kanye nemigodi yomoya, kanye nomgwaqo ongaphansi komhlaba. Izithulisi zokungenisa umoya, ukushaqeka nomsindo ezidepho zesitimela esihamba ngaphansi komhlaba, amagumbi angazwakali, i-KTV, amatiyetha, amachibi okubhukuda angaphakathi, ibhola lomnqakiswano izinkundla nezinye izinkundla.
