Iintlobo eziqhelekileyo zothintelo lwesandi

Ngokokwahlulwa kwezixhobo, isithintelo sesandi sinokwahlulwa sibe ngamacandelo alandelayo: isithintelo sesandi sesinyithi (izivalo zentsimbi, i-aluminium foam), isithintelo sesandi sekhonkrithi (ikhonkrithi ekhaphukhaphu, ikhonkrithi ephezulu), isithintelo sesandi sePC, isithintelo sesandi se-FRP, njl.

Xa kuthelekiswa nezinye izinto eziqhelekileyo zokufunxa isandi, ezifana noboya beglasi kunye ne-asbestos, i-foam ye-aluminium ineempawu zokuzixhasa, ukumelana nobushushu obuphezulu, akukho kukhutshwa kweegesi eziyingozi, ukufunxa umswakama ophantsi kunye nokumelana nemozulu elungileyo. Inamandla amakhulu. Isizukulwana esitsha sezinto ezifunxa isandi. Ngoko ke, isetyenziswa ngokubanzi kwintsimi yokunciphisa ingxolo yezithuthi kunye nobunjineli bokukhuselwa kwendalo, njengokuveliswa kwezithintelo zomsindo ophezulu, iindonga ezithatha isandi, njl.

Izinto ezilungileyo zesithintelo sesandi se-aluminium foam

Ugwebu lwe-aluminiyam lwenziwa ngokongeza izongezo kwi-aluminiyam esulungekileyo okanye ingxubevange ye-aluminiyam kwaye emva koko kuqhutywe inkqubo yogwebu. Ngelo xesha, ineempawu zetsimbi kunye neebhubhu. Ludidi olutsha lwemathiriyeli efunxa isandi esinentunja.

Uncedo lwezithintelo zesandi se-aluminium foam ikakhulu ziquka le miba ilandelayo:

1. Ukusebenza okugqwesileyo kokufunxa isandi

Isithintelo sesandi se-aluminium foam sinomsebenzi ozinzileyo wokufunxa isandi, i-coefficient ye-avareji yokulinganisa isandi sikhulu kune-0.64, kwaye i-coefficient yokunciphisa ingxolo imalunga ne-NRC0.75. Emvuleni okanye emva kokufunxa uthuli, i-coefficient yokufunxa isandi ayiyi kutshintsha, ehlangabezana neemfuno ze-acoustic zokuthintela izandi zendlela.

2. Kulula ukuyifaka

Isithintelo sesandi se-aluminium se-foam senziwe nge-aluminium ecocekileyo, kwaye ibhodi ye-aluminium ye-foam yokufunxa isandi inokubonakaliswa ngokuthe ngqo kwi-atmosphere, ngaphandle kwesidingo somgangatho wobumanzi, i-anti-corrosion layer kunye ne-filler, njl., kwaye kulula, kwaye kulula. ukufaka.

3. Kulula ukugcina kunye nobomi obude

Iiphaneli ze-aluminiyam ezifunxa isandi ziyakwazi ukuhlambeka njengeglasi, kwaye zinokuzicoca ngokwazo ngemvula yendalo. Nokuba uthuli luqokelelana, aluyi kuchaphazela kakubi ukusebenza kwayo kwe-acoustic, kodwa luya kuphucula ukusebenza kwesandi esiphakamileyo. Kwangaxeshanye, inokumelana nemozulu entle, ukumelana nokugqwala kunye nokumelana nokuguga, kwaye ubomi benkonzo bunokufikelela kwiminyaka engaphezu kwama-30.

4. Imbonakalo eyenziwe ngokwezifiso, uhlaza kunye nokukhuselwa kwendalo

Umphezulu we-foam ye-aluminium unokutshizwa nge-fluorocarbon, kwaye umbala unokwenziwa ngokwezifiso ngokweemfuno zomsebenzisi; i-aluminiyam i-foam i-A1 i-fireproof, eluhlaza kunye nongcoliseko, kwaye ayiyi kukhulula izinto ezinobungozi kumaqondo okushisa aphezulu, kwaye ingaphinda isetyenziswe ngokupheleleyo kwaye isetyenziswe kwakhona.

Isakhiwo esiqhelekileyo somqobo wesandi se-aluminium foam

1. "Iphaneli ye-aluminiyam yogwebu efunxa isandi + ipaneli yangasemva yentsimbi"

Ibhodi ye-aluminium ye-foam ehlanganisiweyo ye-sound-absorbing board isetyenziswe ngokuthe ngqo njengepaneli (i-breaking load> 1000N, umphezulu unokuthwala umthwalo we-1500N / m2; ukuphambuka 0.089

2. “Iphaneli yealuminiyam eqholiweyo + iphaneli yealuminiyam yogwebu efunxa isandi + ipaneli yangasemva yentsimbi”

Ibhodi edibeneyo ye-aluminium ye-foam isetyenziswe njengomgangatho wesandwich ophakathi, ngoko i-foam ye-aluminium ingaba ngu-5mm-7mm ubukhulu, obungenayo impembelelo kumthamo wokufunxa isandi kunye nokunciphisa iindleko; ibhodi ye-aluminium ye-foam ehlanganisiweyo ye-sound-absorbing ibhodi ine-coefficient yokufunxa isandi se-0.75, enokuthi ihlangabezane neemfuno ze-viaducts zasezidolophini kuluhlu lwe-200-4000Hz I-coefficient yokufunxa isandi efunwa ngumgangatho wesithintelo sesandi singenza i-cavity ye-resonant malunga ne-50mm, ephucula ngakumbi isiphumo sesandi sokufunxa malunga ne-3dB.

3. “Iphaneli + umzimba oxutyiweyo ofunxa isandi (i-aluminiyam ugwebu + nezinye izinto ezifunxa isandi) + iphaneli yomqolo”

Ngenxa yokuba ubukhulu bepaneli ye-aluminium ye-foam efunxa isandi, amandla angcono kunye nefuthe lokukhusela isandi, kodwa imizimba ephezulu kunye nesezantsi efunxa isandi ikakhulu idlala indima yokufunxa isandi. IYante Material Technology (Luoyang) Co., Ltd. inokwamkela uyilo olukhethekileyo lomqolo webhodi yomqolo yeepaneli ezifunxa isandi + iipaneli ezicekethekileyo zealuminium ezinogwebu kunye nezinye izinto ezifunxa isandi ukwenza imizimba efunxa isandi + iipaneli zeendlela ezahlukeneyo okanye imathiriyeli ngokwe ezona zidingo zabasebenzisi, ukubonelela abasebenzisi ngesikimu soyilo lwephaneli yolwandiso olufunxa isandi esijoliswe kuko.

Isithintelo sesandi se-aluminium foam

I-coefficient ye-absorption coefficient ye-aluminium i-foam engenanto ibhodi ingaphezulu kwe-0.45, kwaye i-coefficient yokuxutywa kwesandi inokufikelela ngaphezu kwe-0.75 emva kwe-perforation kunye nokunyanzeliswa.

Inokumelana nemozulu elungileyo kwaye inokusetyenziswa kakhulu ezindleleni, koololiwe nakwimibhobho kamasipala wasezidolophini.

Ukongeza, izithintelo zesandi se-aluminium amagwebu zinokusetyenziselwa iindonga ezithe nkqo phantsi kwemigangatho yeqonga lezikhululo ze-subway kunye neendonga ezihambelanayo zetonela, amacala aphezulu kunye namabini eetonela zesikhululo, ulawulo lwesikhululo kunye namagumbi ezixhobo, iinqaba zokupholisa zesikhululo kunye ne-air shafts, kunye ne-subway. Izithulisi zokungenisa umoya, ukothuka kunye nokunciphisa ingxolo kwiindawo zokugcina zikaloliwe, amagumbi angavakaliyo, iKTV, iithiyetha, amadama okuqubha angaphakathi, ibhola yomnyazi. amabala emidlalo kunye namanye amabala.
