Aluminium ua npuas ncauj yog tau los ntawm kev sib tov aluminium alloy hmoov nrog cov khoom sib cais thaum lub sij hawm cua sov thiab gasification. Nws muaj cov yam ntxwv ntawm lub teeb yuag, siab porosity thiab siab tshwj xeeb thaj chaw. Nws muaj ob qho tib si cov yam ntxwv ntawm cov ntaub ntawv hlau thiab ua npuas ncauj, thiab muaj kev cuam tshuam tsis zoo, muaj zog tshwj xeeb, kub tsis kam, muaj zog hluav taws kub, thiab tseem muaj zog electromagnetic shielding thiab filtering zog. Niaj hnub no, peb yuav qhia txog xya qhov kev ua tau zoo ntawm txhuas ua npuas ncauj kuaj kom meej.

1. Kev tshuaj xyuas ntawm txhuas ua npuas ncauj - kev ntsuas kev ua tau zoo
Qhov loj tshaj cov qauv ntawm txhuas ua npuas ncauj yog tias nws muaj ntau qhov pores sab hauv, uas ua rau nws lub teeb nyob rau hauv qhov hnyav thiab muaj zog tshwj xeeb. Vim hais tias ntawm cov yam ntxwv no, txhuas ua npuas ncauj ua qhov zoo tshaj plaws sandwich muab tub lim rau sandwich composite panels, uas zoo heev txhim kho lub deformation hom ntawm cov khoom sib xyaw nyob rau hauv load, kom nws khoov tsis kam, compressive zog, thiab suab nrov absorbability muaj peev xwm zoo tuaj. kev txhim kho zoo. Piv nrog rau cov tsoos honeycomb sandwich khoom, cov khoom siv aluminium foamed zoo txo ​​tus nqi thiab kov yeej qhov tsis zoo ntawm anisotropy ntawm honeycomb sandwich khoom.

2. Kev soj ntsuam ntawm cov khoom siv txhuas ua npuas dej - kev soj ntsuam ntawm lub zog nqus kev ua haujlwm
Cov txheej txheem los ntawm kev quab yuam mus rau compression ntawm cov khoom ua npuas ncauj yog muab faib ua peb theem, thawj theem yog elastic deformation theem. Tom qab raug kev ntxhov siab, cov pores sab hauv ntawm cov khoom siv aluminium foamed undergo recoverable elastic deformation. Qhov thib ob theem yog shaping platform theem. Thaum lub zog txhua yam ntawm cov khoom siv foamed aluminium nce mus txog qib irrecoverable, nws nkag mus rau theem shaping deformation. Lub sijhawm no, cov pores sab hauv raug deformation xws li tawm los thiab nkag, thiab thaum kawg tawg tag. Thaum lub degree ntawm lub cev qhuav dej mus txog qhov kev sib cuag ntawm lub opposite pore phab ntsa, nws nkag mus rau lub thib peb theem: lub densification theem. Yog li ntawd, tom qab lub txhuas ua npuas ncauj yog raug rau siab, nws undergoes ib tug tshwj xeeb compression deformation cwj pwm. Nyob rau hauv tus txheej txheem, lub siab yog hloov mus rau hauv lub peev xwm ntawm ua npuas ncauj deformation, uas zoo absorbs lub zog ntawm qhov cuam tshuam quab yuam.

3. Kev soj ntsuam ntawm txhuas ua npuas ncauj - kev soj ntsuam kev ua haujlwm poob siab
Foamed aluminium muaj cov khoom damping siab, 5 mus rau 10 npaug ntawm cov ntshiab txhuas. Cov yam ntxwv no muaj feem xyuam rau qhov porosity, pore loj thiab load-strain amplitude ntawm aluminium npuas nws tus kheej. Qhov siab dua qhov porosity, qhov me me ntawm qhov pore loj thiab qhov loj dua qhov load-strain amplitude, qhov zoo dua qhov damping ntawm aluminium npuas.

Thaum cov khoom siv aluminium foamed raug rau cov kev ntxhov siab sab nraud, vim qhov tsis sib xws ntawm qhov pores, qhov sib txawv ntawm qhov quab yuam kuj tsis sib xws, yog li ntawd lub zog ntawm lub cev raug hloov mus rau kev ntxhov siab, uas siv cov kev ntxhov siab sab nraud thiab hloov mus rau hauv thermal zog hauv lub cev. foamed aluminium khoom. Raws li cov yam ntxwv ntawm cov khoom siv foamed aluminium, foamed aluminium cov ntaub ntawv dhau los ua cov khoom zoo heev absorbing. Xws li lub tsheb bumpers, tsaws iav ntawm spaceships, thiab lwm yam.

4. Aluminium ua npuas ncauj kuaj - lub suab nqus kev ua tau zoo tsom xam
Qhov tshwj xeeb pore qauv ntawm cov khoom siv aluminium ua npuas ncauj ua rau nws muaj suab nrov zoo. Thaum lub suab dhau los ntawm qhov pore, nws ua rau lub suab nrov hauv qhov pore, thiab kev sib txhuam nrog lub pore phab ntsa tsim hluav taws xob hluav taws xob, thiab lub zog hluav taws xob yog dissipated los ntawm txhuas, yog li lub pore qauv ntawm foamed aluminium khoom zoo. absorbs lub suab nrov. Lub suab nqus kev ua tau zoo ntawm cov khoom siv foamed aluminium nce nrog qhov nce ntawm porosity, txo qhov pore loj thiab nce ntawm cov khoom thickness. Raws li lub suab nqus cov khoom ntawm txhuas ua npuas ncauj, nws yog dav siv hauv xov tooj cua kaw studios thiab cov khoom siv hauv chaw ua haujlwm tsis siv neeg.

5. Kev soj ntsuam ntawm txhuas ua npuas ncauj - tsom xam ntawm electromagnetic shielding kev ua tau zoo
Kev tshawb fawb thiab kev sim qhia tau hais tias cov khoom siv foamed aluminium muaj qhov zoo electromagnetic shielding kev ua tau zoo. Thaum lub high-frequency magnetic teb dhau los ntawm lub npuas, ib tug eddy tam sim no magnetic teb yog generated nyob rau hauv lub npaus, uas tshem tawm qhov qub magnetic teb. Raws li qhov kev ua tau zoo no, cov khoom siv aluminium foamed yog siv rau hauv chav tsev khoom siv hluav taws xob thiab cov khoom siv hluav taws xob,

Hauv cov ntaub thaiv npog rau cov khoom siv hluav taws xob.

6. Kev soj ntsuam ntawm cov khoom siv txhuas ua npuas dej - kev tsom xam ntawm kev sib pauv cua sov thiab thermal rwb thaiv tsev kev ua haujlwm
Vim tias cov khoom siv txhuas ua npuas dej muaj ntau cov npuas huab cua nrog lub peev xwm hloov hluav taws xob me me, nws cov thermal conductivity tsis siab npaum li cov txhuas, tab sis nws zoo dua li cov yas foamed. Nws cov thermal conductivity cuam tshuam los ntawm porosity, thiab qhov siab dua qhov porosity, qhov ua rau thermal conductivity tsis zoo. Nyob rau hauv ntuj convection tej yam kev mob, tshav kub dissipated los ntawm tshav kub pauv ntawm cov roj los yog kua thiab lub pore phab ntsa. Qhov no ua rau aluminium ua npuas ncauj zoo sib pauv cua sov lossis cov khoom siv cua sov. Piv txwv li, lub tshuab deicing yog ntsia rau pem hauv ntej ntawm lub dav hlau tis, thiab cov roj rhuab los yog cov tshuaj tiv thaiv kab mob yog ejected los ntawm foamed aluminium khoom kom ua tiav lub hom phiaj ntawm deicing.

7. Aluminium ua npuas ncauj - pom kev ua tau zoo tsom xam
Vim lub permeability ntawm txhuas ua npuas ncauj, nws yuav siv tau raws li ib tug zoo lim cov ntaub ntawv nyob rau hauv lom thiab tshuaj lom neeg teb. Cov pores nyob rau hauv cov khoom ua npuas ncauj aluminium muaj qhov zoo lim thiab sib cais ntawm cov pa roj los yog kua, thiab tuaj yeem lim cov khoom cua.
