Amacandelo e-acoustic eyenziwe nge-Yadina melamine foam kwaye igqunywe ngefoyile ye-aluminiyam okanye amalaphu angangeni manzi angalukwanga asetyenziswa kunyango lwengxolo yamagumbi enjini yomkhosi wasemanzini.Abavelisi abaxhasa iinqwelomoya baye basebenzisa igwebu lemelamine ukugcwalisa izihlalo zenqwelomoya.Ukongeza ekuthatheni ithuba lokufunxa isandi esigqwesileyo kunye neempawu zokubuyiswa komlilo, izihlalo zenqwelomoya ezinegwebu lemelamine zikhaphukhaphu kakhulu kunezihlalo zesintu.Ukusebenzisa izihlalo ezininzi kwinqwelomoya yongeza ukonga ubunzima obuninzi.Ngokobalo lomenzi wenqwelomoya, ekubeni ubunzima besihlalo buncitshiswe nge-50% ukuya kwi-70%, iindleko zepetroli ezigciniweyo zinokuhlawula iindleko zokutshintsha isihlalo kwiinyanga ezimbini, ezisa inzuzo ephindwe kabini kwezoqoqosho kunye nokusingqongileyo kwinqwelomoya. .
Ubuninzi obuphantsi kunye neempawu eziphezulu zokufunxa isandi se-Yadina melamine foam nazo ziyenza ibe luncedo kwibala lokubhabha.Izixhobo ze-acoustic ezenziwe nge-Yadina melamine foam kwaye zigqunywe nge-aluminium foil zisetyenziswa kwindawo yokuhlawula i-rocket launcher.Ukuseta okunjalo kunokunciphisa uxinzelelo lwe-acoustic, olunokukhusela kakuhle izixhobo ezibuthathaka kakhulu kunye nezixhobo zothutho, ezifana neesathelayithi ezenziweyo.Amacandelo e-acoustic eyenziwe nge-Yadina melamine foam kwaye igqunywe ngefoyile ye-aluminiyam okanye amalaphu angangeni manzi angalukwanga asetyenziswa kunyango lwengxolo yamagumbi enjini yomkhosi wasemanzini.I-Yadina melamine foam, njengento ephantsi yoxinano lwe-thermal kunye nezixhobo zokunciphisa ingxolo (i-thermal conductivity 0.034w/(mk), i-B1 level flame retardant), isetyenziswe ngokubanzi kwizihlalo zokuhamba ngeenqwelomoya, iikhabhinethi zeenqanawa zabakhweli, amagumbi eenjini zokulwa, i-liquefaction yobushushu obuphantsi. iinqwelomoya kunye neesathelayithi.Indalo ekhanyayo kakhulu ye-Yadina melamine foam (6-12kg/m³) yehlisa ubunzima bekhabhathi xa iyonke ngelixa inciphisa ingxolo.Njengemveliso engeyo-fibrous, akusayi kubakho kuchithwa kwefiber ngexesha lokubhabha.I-foam ye-melamine igcwele ngaphakathi kwi-cabin cavity, engadlali nje indima esebenzayo yokufudumala ukushisa, kodwa inokumelana nokushisa okuphezulu kwe-240 ° kunye nokushisa okuphantsi kwe-200 °, kwaye inokugcina ukuqina kwayo.Yeyona nto ibalaseleyo yokunciphisa ingxolo yenqwelomoya kunye nemathiriyeli yokugquma ubushushu.
