1. Hais lus nta:
Kev ua haujlwm ntawm lub suab nrov: Lub kaw-cell ua npuas ncauj aluminium phaj tuaj yeem perforated los ua lub suab haum lub suab nrog lub suab nrov txaus. Thaum qhib tus nqi yog 1% ~ 3%, lub suab nqus tau siab tshaj plaws. Lub suab nqus tus nqi ntsuas los ntawm txoj kev yoj sawv ntsug yog nyob rau hauv thaj tsam ntawm 1000Hz txog 2000Hz, thiab lub suab nqus tau nce mus txog 40% txog 80%.
Suab rwb thaiv tsev ua npuas ncauj aluminium: suab rwb thaiv tsev board ua los ntawm ua npuas ncauj aluminium sandwich vaj huam sib luag, 20mm tuab, suab rwb thaiv tsev: 20 ~ 40dB.
2. Huab cua tsis kam:
Corrosion tsis kam: raug rau cov huab cua hauv hiav txwv rau ib xyoos, tsis pom qhov txawv txav; nyob rau hauv cov txheej txheem nrawm nrawm, cov tshuaj tsuag dej ntsev tshuaj tsuag tsis muaj qhov txawv txav rau 2 xyoos; nws qhia tau hais tias corrosion kuj ntawm foamed aluminium yog zoo heev.
Tsis muaj dej noo: Qhov nqus noo noo ntawm foamed aluminium yog 0.0%. Tsis muaj noo noo nqus, thiab tsis muaj degradation ntawm acoustic kev ua tau zoo vim cov av noo.
Thaum tshav kub kub-resistant / non-combustible zog: Foamed aluminium softens ntawm qhov kub ntawm 600 ° C, thiab yog ib yam khoom uas tsis-combustible.
Rwb thaiv tsev kev ua tau zoo: Lub thermal conductivity ntawm foamed aluminium yog 0.25 ~ 0.62W / mK, uas yog sib npaug rau cov marble, thiab muaj kev rwb thaiv tsev zoo.
Thermal stability: Lub linear expansion coefficient ntawm foamed aluminium yog 1.934 * 10 ℃, uas yog sib npaug rau pob zeb, thiab nws tsis yooj yim rau deformed los ntawm tshav kub.
3. Mechanical zog:
Mechanical zog: compressive zog: 3 txog 17 MPa; flexural zog: 3-15 MPa; tensile zog: 2-7 MPa;
Cushioning kev ua tau zoo: Lub zog nqus tuaj yeem ncav cuag 8J / cm3 ~ 30J / cm3, thiab cov foamed aluminium tuaj yeem nqus tau lub zog los ntawm kev deformation, uas yog ib qho zoo heev cuam tshuam rau lub zog nqus khoom.
4. Machining kev ua tau zoo:
Aluminium ua npuas ncauj yog dav siv nyob rau hauv ntau yam teb. Nws yog cov khoom ntxeem tau, lub teeb thiab nyiaj-dawb hlau nrog cov yam ntxwv zoo ntawm kev ua haujlwm yooj yim. Nws tuaj yeem saws, txiav, npaj, milled, thiab lwm yam, thiab tuaj yeem ua tau yooj yim rau hauv daim hlau thiab strips. Bars thiab ntau yam tshwj xeeb-puab qhov chaw.
5. Kev tiv thaiv ib puag ncig ntsuab:
Non-toxic: Aluminium ua npuas ncauj yog cov khoom sib xyaw ua ke ntawm cov hlau thiab qhov pores, uas tsis muaj tshuaj lom thiab yuav tsis dim pa phem ntawm qhov kub thiab txias.
Recyclable: Cov khoom siv tshuaj tseem ceeb ntawm txhuas ua npuas ncauj yog aluminium alloys thiab lawv cov oxides, uas tuaj yeem ua 100% rov ua dua yam tsis muaj kuab paug rau ib puag ncig.
Electromagnetic shielding: Electromagnetic shielding (hauv qab 200MHz) shielding electromagnetic shielding 90dB, nrog zoo heev electromagnetic shielding kev ua tau zoo.
6. Cov khoom thov teb
Vim nws cov khoom tshwj xeeb, cov khoom siv txhuas ua npuas dej tuaj yeem siv dav hauv aerospace, aviation, high-speed tsheb ciav hlau, tsheb ciav hlau hauv nroog, shipbuilding, high-speed rail, kev tsim kho, tunnels thiab suab barriers raws txoj kev. kev poob siab, siab nqus ntawm lub zog cuam tshuam, siab electromagnetic shielding kev ua tau zoo, zoo heev tshav kub rwb thaiv tsev, kub tsis kam, hluav taws kub tsis kam thiab tsis-combustibility. Nws muaj qhov tshwj xeeb ib puag ncig tus phooj ywg.
Kev ua haujlwm tsis zoo: Kev sim los ntawm Lub Tsev Haujlwm ntawm Lub Xeev Lub Zog Physics, Suav Academy ntawm Kev Tshawb Fawb, qhov kev sib txhuam sab hauv Q-1 ntawm ua npuas ncauj aluminium ncav cuag 6 × 10-3.
