Aluminium foamed yog tsim los ntawm kev ntxiv additives rau ntshiab txhuas los yog txhuas alloy los ntawm cov txheej txheem foaming, thiab muaj ob qho tib si hlau thiab npuas cov yam ntxwv. Nws muaj tsawg ntom ntom, lub peev xwm nqus tau muaj peev xwm, cov hluav taws xob muaj zog, kev ua kom muaj zog, yooj yim, nruab nrog yooj yim, thiab siab txoj kev raug, txheej txheej tuaj yeem nqa tawm.

Aluminium foamed yog ib yam tshiab ntawm lub teeb hlau khoom tsim los ntawm aluminium alloy foaming. Nws muaj tsawg ntom ntom thiab lub zog muaj zog. Nws muaj ntau yam zoo heev xws li lub suab nqus thiab suab rwb thaiv tsev, lub zog nqus thiab cushioning, nplaim hluav taws kub thiab tawg-pov thawj. Nws yog dav siv nyob rau hauv tub rog aerospace, rail transit, nkoj manufacturing, thiab lwm yam khoom teb. Ntawm qhov "Top Ten Feem Ntau Cov Khoom Muaj Peev Xwm Tshiab nyob rau yav tom ntej" xaiv los ntawm cov xov xwm txawv teb chaws, cov khoom siv txhuas ua npuas dej tau nyob rau thib rau.

Peb tuaj yeem kho ua npuas ncauj aluminium profiles nrog ntau yam apertures, thicknesses thiab cov kev cai raws li kev tsim qauv.

1. Cov yam ntxwv ua tau zoo

① Lub teeb yuag: Qhov ntom yog 0.1-0.4 npaug ntawm cov xim hlau;

② Kev nruj nruj: nws txoj kev nruj nruj yog 1.5 npaug ntawm cov hlau;

③ High damping shock absorption kev ua tau zoo thiab cuam tshuam lub zog nqus tus nqi:damping kev ua tau zoo yog5-10lub sij hawm ntawm hlau aluminium. Porosity Thaum cov txhuas ua npuas ncauj nrog tus nqi ntawm 84% yog deformed los ntawm 50%, nws tuaj yeem nqus tau ntau dua 2.5MJ / cm3 ntawm lub zog.

④ Zoo acoustic muaj nuj nqi: 1. Suab rwb thaiv tsev kev ua tau zoo (kaw cell): Thaum lubsuab yoj zaus yog nyob nruab nrab ntawm 800-4000HZ, Lub suab rwb thaiv tsev coefficient ntawm kaw-cell aluminium ua npuas ncauj yog siab dua 0.9. 2. Kev ua haujlwm ntawm lub suab (micro los ntawm qhov thiab los ntawm qhov): Thaum lub suab nthwv dej zaus nyob nruab nrab ntawm 125-4000HZ, qhov siab tshaj plaws suab nqus coefficient ntawm lub qhov txhuas ua npuas dej tuaj yeem ncav cuag 0.8, thiab qhov nruab nrab suab nqus coefficient ntawm octave band. tshaj 0.4.

⑤ Kev ua haujlwm zoo ntawm electromagnetic shielding: thaum electromagnetic yoj zaus nyob nruab nrab ntawm 2.6-18GHZ, electromagnetic, qhov shielding npaum li cas tuaj yeem ncav cuag 60-90dB.

⑥ Cov khoom zoo thermal: Lub thermal conductivity ntawm kaw-cell aluminium ua npuas ncauj nrog ib tug porosity ntawm 80-90% yog 0.3-1W / m # 8226; k, sib npaug rau marble. Lub qhov los ntawm lub qhov txhuas ua npuas dej muaj qhov ua tau zoo thaum tshav kub kub dissipation nyob rau hauv yuam convection tej yam kev mob vim lub interconnection ntawm pores.

⑦ tsis hlawv thiab muaj cua sov zoo. □ Zoo corrosion kuj, huab cua tsis kam, tsis muaj noo noo nqus, tsis muaj kev laus, Tsis muaj tshuaj lom.

⑧ Cov txheej txheem yooj yim: yooj yim rau kev txiav, drilling, thiab cementing; nws tuaj yeem khoov rau hauv qhov xav tau los ntawm molding; nws tuaj yeem siv cov xim organic lossis Inorganic yog siv rau kev kho deg; nws tuaj yeem pleev xim rau ntawm ob sab los tsim ib lub teeb loj loj, siab-rigidity board. Tam sim no qhov loj me: 600x1200x5 / 10MM, 500x1000x5 / 10MM.

⑨ Yooj yim rau nruab: Cov khoom siv aluminium foamed tuaj yeem ntsia tau rau ntawm qhov chaw siab yam tsis muaj cov cuab yeej nqa khoom, xws li: qab nthab, phab ntsa thiab ru tsev, thiab lwm yam., tuaj yeem txuas thiab kho los ntawm kev siv tshuab lossis ncaj qha nrog cov ntsia hlau, lossis lawv tuaj yeem txuas thiab kho los ntawm kev siv tshuab lossis ncaj qha nrog cov ntsia hlau, lossis lawv tuaj yeem ua tau. muab tso rau ntawm phab ntsa lossis qab nthab nrog cov nplaum.

⑩ Cov qauv "sandwich" tsim los ntawm nyias hlau phaj-aluminium ua npuas ncauj-cov phaj hlau nyias tau txais txiaj ntsig zoo ntawm txhuas ua npuas ncauj sib txawv thiab siab khoov lub zog, tuaj yeem siv los ua cov khoom siv hauv tsev tshiab, cov khoom siv zoo ntawm cov khoom dov, lwm.

2. Cov yam ntxwv zoo

• Qhov loj aperture yog 0.3-7mm;
• Siab thiab tswj tau porosity: 63% -90%;
• Qhov chaw tshwj xeeb yog 10-45cm2 / cm3;
• Diversified cell qauv; kaw cell, los ntawm cell thiab micro los ntawm cell aluminium ua npuas ncauj;
• Qhov sib xyaw thiab pore qauv ntawm cov txheej txheem hlau yog tswj tau, uas tuaj yeem hloov mus rau qhov sib txawv xav tau.

3. Scope ntawm daim ntawv thov

Cov khoom siv suab nrov thiab suab rwb thaiv tsev: aluminium foamed tuaj yeem siv rau kev tswj lub suab nrov ntawm lub nroog lub teeb rails, elevated highways, underground tunnels, mechanical equipment, and improvement of acoustic room, multi-function halls and other indoor sound effects. Lub suab-absorbing aluminium ua npuas ncauj yog glued mus rau lub pob zeb los yog steel qauv thiab tsim rau ntawm ob sab ntawm viaducts thiab lub teeb rails raws li loj-scale suab-absorbing phab ntsa, uas yuav txo tau lub suab nrov hauv nroog. Lub suab rwb thaiv tsev aluminium foamed tuaj yeem siv rau kev sib cais suab nrov hauv chav tsev computer, tshuab thiab khoom siv, thiab cov chaw tsim kho sab nraum zoov, thiab daws tau ntau yam kev txwv ntawm cov khoom siv suab nrov tam sim no xws li iav ntaub plaub thiab asbestos.

4. Cov chaw thov

aluminium foamed tuaj yeem tsim cov khoom tsim nyog los ntawm kev hloov nws qhov ntom ntom thiab pore qauv. Qhov no yog qhov ntxim nyiam ntawm cov khoom siv tshwj xeeb no. Yog li ntawd, nws yog dav siv nyob rau hauv ntau lub teb.
