Aluminium ua npuas ncauj yog tsim los ntawm kev ntxiv additives rau ntshiab txhuas los yog txhuas alloy los ntawm cov txheej txheem foaming, thiab muaj cov yam ntxwv ntawm cov hlau thiab npuas tib lub sijhawm. Cov txheej txheem tsim khoom yog xa cov molten aluminium alloy mus rau lub thawv foaming, txhaj roj los ua cov kua ua npuas dej, thiab tom qab cov kua ua npuas dej khov, nws yuav tsim cov duab uas yuav tsum tau ua.

Aluminium ua npuas ncauj kev ua haujlwm

1. Lub teeb yuag

Qhov ceev yog 0.2 ~ 0.4g / cm3, uas yog hais txog 1/10 ntawm qhov ceev ntawm txhuas, 1/20 ntawm qhov ceev ntawm titanium, 1/30 ntawm qhov ntom ntawm hlau, 1/30 ntawm qhov ntom ntawm cov hlau, thiab 1/3 ntawm qhov ntom ntawm ntoo.

2, suab absorption

Thaum lub suab nkag mus rau hauv cov npuas dej, nws yuav diffusely reflected thiab cuam tshuam rau ib leeg, kom lub suab zog hloov mus rau hauv lub zog cua sov thiab lub suab tsis muaj zog.

Piv nrog rau lwm cov ntaub ntawv suab-absorbing, qhov tsawg zaus nqus dej ua tau zoo heev, ntxiv rau qee qhov me me kab noj hniav, cov nyhuv nqus suab zoo dua, thiab nws tuaj yeem siv tau ntau zaus.

Piv txwv li: ua ntej kev kho lub suab sab hauv tsev, phab ntsa yog ua los ntawm cov cement nyuaj heev. Tom qab chav tsev yog pasted nrog 10 hli tuab npuas aluminium panels rau lub suab nqus thiab txo suab nrov kho, lub suab nqus tuaj yeem txo lub suab nrov los ntawm 20-30dB.

3. Suab rwb thaiv tsev

Nws tuaj yeem sib xyaw nrog lwm cov khoom siv suab rwb thaiv tsev. Vim lub suab nqus ntawm foamed aluminium, lub suab rwb thaiv tsev tuaj yeem txhim kho ntxiv.

4. Kev tiv thaiv hluav taws

Nws muaj hluav taws kub zoo. Lub melting point ntawm txhuas yog 660 ℃, thiab cov foamed aluminium pib mos (vim nws tsis tuaj yeem ris nws tus kheej qhov hnyav), tab sis nws tsis tau yaj mus txog 800 ℃.

Thaum tsis muaj kev quab yuam sab nraud, nws yuav tsis deform txawm tias raug kub ntawm 780 ℃, thiab yuav tiv taus qhov kub thiab txias dua li cov khoom siv suab nrov.

Tsis tas li ntawd, foamed aluminium yog cov khoom uas tsis yog-combustible thiab yuav tsis tsim cov pa phem xws li yas thiab lwm yam ntaub ntawv.

5. Electromagnetic shielding

Nws muaj kev ua tau zoo ntawm electromagnetic shielding kev ua tau zoo thiab kuj muaj cov yam ntxwv ntawm lub suab nrov.

Nws yog qhov tsim nyog tshaj plaws rau kev ua lub qab nthab thiab phab ntsa ntawm cov khoom siv hluav taws xob hauv chav ua hluav taws xob tiv thaiv cov ntaub ntawv.

6, Zoo zog nqus thiab buffering
Thaum lub siab nce mus txog qhov taw tes tawm, cov npuas diaphragm deforms, tsis tu ncua deforming txheej los ntawm txheej, thiab npuas tawg, ua rau lub compression deformation zoo, yog li absorbing lub zog cuam tshuam thiab qhia cov nyhuv cushioning zoo.

7, yooj yim rau txheej txheem

Nws yog ib qho yooj yim rau kev ua txhua yam, xws li txiav, drilling, khoov thiab embossing.

Lub rooj tsavxwm ua npuas ncauj tuaj yeem txiav rau hauv qhov sib txawv thiab qhov ntau thiab tsawg nrog cov saw, uas tuaj yeem yooj yim drilled thiab riveted, kuj tuaj yeem khoov thiab embossed, thiab tuaj yeem txuas rau ib leeg nrog cov nplaum.

8. Kev tsim kho yooj yim

Lub teeb nyhav, tuaj yeem ntsia tau manually, tshwj xeeb tshaj yog tsim rau qab nthab, phab ntsa, ru tsev thiab lwm qhov chaw siab.

Vim qhov yooj yim ntawm kev ua, kev sib txuas thiab riveting tuaj yeem ua tau, thiab nws yooj yim rau kev sib txuas nrog lwm cov qauv.

Yog li ntawd, nws yooj yim rau kev tsim kho ntawm qhov chaw thiab kev teeb tsa ua ke.

9, cov nyhuv kho kom zoo nkauj saum npoo yog qhov zoo

Siv cov txheej txheem tshwj xeeb, sab nrauv tuaj yeem pleev xim rau xim.

Txheej hardly puas nws lub suab-absorbing nyhuv.

10, tuaj yeem siv los ua cov qhaub cij

Bonding aluminium, tooj liab, titanium thiab lwm daim hlau nyias ntawm ob sab los ua ib lub phaj sandwich, uas tuaj yeem ua rau lub teeb yuag thiab lub zog siab, uas tuaj yeem siv los ua cov khoom siv nrog kev ua haujlwm zoo.
