I-FOAM Industry Innovation |Yintoni i-Acoustic Foam

Ngokwendalo, amalulwane asebenzisa i-echolocation ye-ultrasonic ukufumana amaxhoba abo, kwaye kwangaxeshanye, ixhoba liye lavelisa ukhuseleko - ezinye iinundu zinokufunxa ngokufanelekileyo amaza e-ultrasonic ngokusebenzisa izakhiwo ezintle kumaphiko azo ukuphepha izibonakaliso ezivakalayo ezibonisa indawo yazo.Eli lixesha lokuqala izazinzulu zifumanisa imathiriyeli ye-acoustic kwindalo.Nangona amaphiko enundu ejolise kumaza e-ultrasonic (i-vibration frequency inkulu kune-20,000 Hz), imigaqo yabo yokufunxa isandi iyahambelana nazo zonke iintlobo zezinto ezifunxa isandi esizibonayo ebomini bethu, kodwa le yokugqibela Lungisa uyilo olufanayo ukuya rhoqo. ibhendi (20Hz-20000Hz) ngokuhambelana nokuva kwabantu.Namhlanje, makhe sithethe ngezixhobo ze-foam ezinxulumene ne-NVH.

Isandi sisuka kungcangcazelo lwento, kwaye sisisenzeko samaza esisasazeka ngesixhobo esiphakathi kwaye sinokuqondwa lilungu elivavanyayo lomntu.I-NVH ibhekisa kwingxolo (ingxolo), ukungcangcazela (ukungcangcazela) kunye noburhabaxa (uburhalarhume), apho ingxolo kunye nokungcangcazela zezona ziviwa ngokuthe ngqo kuthi, ngelixa uburhabaxa besandi busetyenziswa ikakhulu ukuchaza umbono womzimba womntu wokungcangcazela kunye nengxolo. .ukuziva ungakhululekanga.Ekubeni ezi zintathu zivela ngexesha elinye kwi-vibration yomatshini kwaye azikwazi ukwahlula, zihlala zifundwa kunye.

Njengoko kubonisiwe kumzobo ongezantsi, xa isandi singeniswa kwizinto eziphathekayo okanye kumphezulu wecandelo lolwakhiwo lwe-acoustic, inxalenye yamandla omsindo ibonakaliswe, inxalenye yayo ingena kwizinto eziphathekayo, kwaye inxalenye yayo ifunnwe yinto, leyo kukungqubuzana phakathi kwesandi kunye nendawo ejikelezileyo ngexesha losasazo okanye impembelelo yesixhobo.Ukungcangcazela, inkqubo apho amandla esandi aguqulwa abe bubushushu kwaye alahleke.Ngokuqhelekileyo, nawuphi na umbandela unokufunxa kwaye ubonakalise isandi, kodwa umlinganiselo wokufunxa nokucamngca wahluka kakhulu.

Izinto ze-NVH zohlulwe kakhulu zibe ziindidi ezimbini: izixhobo ezifunxa isandi kunye nezixhobo zokukhusela isandi.Xa isandi sesandi singena kwizinto ezifunxa isandi, siya kubangela ukuba umoya kunye nemicu ekwisixhobo singcangcazele, yaye amandla esandi aya kuguqulwa abe ngamandla obushushu yaye inxalenye yawo iya kutyiwa, kanye njengokubetha isipontshi ngesixhobo sokutshiza. inqindi.
Isixhobo sokugquma isandi sisixhobo esisetyenziselwa ukuthintela ingxolo, njengenqindi elibetha ikhaka kwaye liyithintele ngokuthe ngqo.Izinto zokugquma isandi zixinene kwaye azinaporeshi, kwaye kunzima ukuba amaza omsindo angene ngaphakathi, kwaye uninzi lwamandla omsindo abonakaliswa ngasemva, ukuze kufezekiswe isiphumo sokugquma isandi.

Izinto ezixutywe ne-foam ezine-porous structure zineenzuzo ezikhethekileyo ekufunxeni isandi.Izinto eziphathekayo ezinokwakheka kwe-microporous ezixineneyo zide zibe nefuthe elihle lokugquma isandi.Amagwebu e-acoustic e-NHV aqhelekileyo aquka i-polyurethane, i-polyolefin, i-rubber resin, kunye neglasi.I-Foam, i-foam yensimbi, njl., ngenxa yeempawu ezahlukeneyo zezinto ngokwazo, umphumo wokuxutywa kwesandi kunye nokunciphisa ingxolo kuya kuhluka.

I-polyurethane foam

Isixhobo se-Polyurethane foam sinesakhiwo saso sothungelwano esisodwa, esinokufunxa isixa esikhulu samandla angenayo amaza omsindo ukuze sifezekise isiphumo esilungileyo sokufunxa isandi, kwaye kwangaxeshanye sinobuxhakaxhaka obuphezulu kunye nomsebenzi olungileyo wokubhafa.Nangona kunjalo, amandla e-foam ye-polyurethane eqhelekileyo aphantsi, kwaye isiphumo sokugquma isandi sibi, kwaye ukusebenza kwayo kokufunxa isandi kuya kuncipha ngokuhamba kwexesha.Ukongezelela, ukutshisa kuya kuvelisa igesi enetyhefu, engenabuhlobo kwimekobume.

XPE/IXPE/IXPP polyolefin imathiriyeli yogwebu

I-XPE/IXPE/IXPP, i-chemically cross-linked/electronic cross-linked polyethylene/polypropylene foam material, inesandi sendalo sokufunxa, i-thermal insulation, i-cushioning kunye nokukhuselwa kwendalo, kunye nesakhiwo sayo sangaphakathi esilungileyo se-bubble esizimeleyo silungile ukugquma isandi kunye nokunciphisa ingxolo.Ukusebenza okugqwesileyo.

ugwebu lwerabha

Irabha enegwebu yinto efanelekileyo ye-NVH, kunye nezinto ezifana ne-silicone, i-ethylene-propylene-diene rubber (EPDM), irabha ye-nitrile-butadiene (NBR), i-neoprene (CR), kunye ne-styrene-butadiene rubber (SBR) ingcono kuneyangaphambili. izixhobo ezimbini., Ubuninzi buphezulu, kwaye ingaphakathi ligcwele i-voids encinci kunye nezakhiwo ezivulekileyo, ekulula ukufunxa amandla omsindo, kunzima ukungena, kunye nokunciphisa amaza omsindo.

i-melamine resin foam

I-Melamine resin foam (i-melamine foam) yeyona nto ibalaseleyo efunxa isandi.Inenkqubo yesakhiwo segridi enemigangatho emithathu enemivulo eyaneleyo.I-vibration idliwe kwaye ifakwe, kwaye i-wave ebonakalisiweyo inokupheliswa ngokufanelekileyo ngexesha elifanayo.Kwangaxeshanye, ineenzuzo ezininzi ezisebenzayo kunye nezilungelelanisiweyo kunezixhobo zemveli zefoam ngokwemiqathango yokuncipha komlilo, ukugqunywa kobushushu, ubunzima bokukhanya kunye nokumila kokulungiswa.
aluminiyam yogwebu

Yongeza izongezo kwi-aluminiyam esulungekileyo etyhidiweyo okanye ialloyi ye-aluminiyam kwaye uyithumele kwibhokisi enogwebu, ugalele igesi ukwenza ugwebu olulwelo, kwaye uqinise igwebu elulwelo ukwenza imathiriyeli yesinyithi.Inesakhono sokugquma isandi esilungileyo, kwaye ukusebenza kwesandi kuthathe ixesha elide ngokwentelekiso, ubomi benkonzo obusebenzayo bunokufikelela kwiminyaka engama-70, kwaye inokuphinda isetyenziswe kwaye isetyenziswe kwakhona nge-100%.
iglasi yogwebu

Yimathiriyeli yeglasi engeyiyo eyentsimbi eyenziwe ngeglasi eyaphukileyo, i-ejenti enogwebu, izongezo ezilungisiweyo kunye ne-accelerator enegwebu, njl.njl., emva kokuba icoliwe kwaye ixutywe ngokulinganayo, emva koko inyibilika kubushushu obuphezulu, igwebu kwaye ifakwe i-annealed.

Kubomi bokwenyani, kuhlala kungekho nto inokufunxa ngokupheleleyo amaza esandi kwiibhendi zamaza ahlukeneyo, kwaye akukho nto inokusebenza ngokungenasiphako kwizicelo.Ukuze sifezekise isiphumo esingcono sokufunxa isandi, sihlala sibona indibaniselwano yale magwebu e-acoustic angasentla kunye nabo kunye neentlobo zokufunxa isandi / izixhobo zokugquma isandi ukwenza izinto ezahlukeneyo ze-foam ezidityanisiweyo, kwaye ngaxeshanye ukufikelela kwisiphumo. ukufunxwa kwesandi semathiriyeli kunye nolwakhiwo lokufunxa isandi, ukufezekisa ukusebenza kwesandi sokufunxa kwezixhobo kwiibhendi zamaza ahlukeneyo amatyeli aphezulu kunye namaza aphantsi.Umzekelo, inkqubo ehlanganisiweyo ye-acoustic foam kunye neenkqubo ezahlukeneyo ezingalukwanga zingasebenzisa ngokupheleleyo isakhiwo esikhethekileyo esine-dimensional ezintathu zokugqibela ukunciphisa ngokufanelekileyo ukungcangcazela kwamaza omsindo, ukudala amathuba angenasiphelo okufunxa isandi kunye nokunciphisa ingxolo;) I-foam sandwich layer composite material, amacala amabini elulusu adityaniswe nekhabhon fiber eqinisiwe imathiriyeli, enobulukhuni obuphezulu bomatshini kunye namandla empembelelo eyomeleleyo, ngaloo ndlela ifezekisa ukothuka okungcono kunye nokunciphisa ingxolo.

Okwangoku, izixhobo ze-foam ze-NVH zisetyenziswa ngokubanzi kwezothutho, ubunjineli bokwakha, ukunciphisa ingxolo yoshishino, ukuveliswa kwezithuthi kunye nezinye iindawo.

Ezothutho

ulwakhiwo lwezothutho lwasezidolophini lwelizwe lam lungene kwinqanaba lophuhliso olukhawulezayo, kwaye ukuphazamiseka kwengxolo okunjengeemoto, oololiwe, ukuhamba ngololiwe ezidolophini, noololiwe bemaglev kuye kwatsala ingqalelo ebanzi.Kwixesha elizayo, i-acoustic foam kunye nezixhobo zayo ezidibeneyo zinamandla amakhulu okusebenza kwi-insulation yesandi kunye nokunciphisa ingxolo yeendlela ezihamba phambili kunye nokuhamba kwedolophu.
