Aluminium ua npuas ncauj zoo ib yam li daim txhuam cev thiab yog lub npe hu ua universal hlau, nrog ib tug tsawg ntom thiab lub teeb yuag, siv raws li ib tug tiv thaiv txheej rau qhov chaw tsheb, resistant rau compression thiab muaj peev xwm tiv taus hluav taws xob vim hluav taws xob impulses. Nws yog cov khoom siv hlau tshiab ua los ntawm foamed aluminium alloy.

Raws li dav siv zog-absorbing cov ntaub ntawv tiv thaiv, daim ntawv thov ntawm aluminium foam sandwich (AFS) panels tseem txwv los ntawm lub inherently tsawg mechanical zog ntawm cov tub ntxhais ua npuas ncauj. Kev koom ua ke ntawm coppercoated carbon fibers (Cf) tau ua pov thawj tias muaj txiaj ntsig zoo hauv kev txhim kho cov khoom siv ntawm txhuas ua npuas ncauj.

Txawm li cas los xij, kev nkag siab ntawm nws cov txheej txheem foaming thiab microstructure tseem txwv. Hauv kev ua haujlwm no, AFS thiab Cf / AFS tau tsim los ntawm kev ntim cov hmoov hlau metallurgy. Tus cwj pwm foaming ntawm AFS thiab Cf / AFS thaum kub siab yog nyob rau hauv situ pom siv synchrotron hluav taws xob X-ray imaging technology los soj ntsuam cov nyhuv ntawm Cf ntawm npuas nucleation, kev loj hlob, thiab ua npuas ncauj stability. Tsis tas li ntawd, macroscopic pore loj faib, microscopic microstructure, thiab compressive mechanical zog ntawm AFS thiab Cf / AFS tau soj ntsuam. Cov txiaj ntsig tau pom tias qhov muaj nyob ntawm Cf ua rau muaj txiaj ntsig zoo ntawm cov nucleation, txhim kho cov foaming stability, thiab tiv thaiv kev tsim ntawm cov npuas loj hauv zos thaum lub sij hawm ntxov nucleation thiab kev loj hlob. Lub caij no, Cf/AFS nthuav tawm cov pore diameters zoo dua thiab tsawg dua pore tsis xws li AFS. Kev faib tawm ntawm Cf nrog zoo wettability raws lub pore phab ntsa tiv thaiv kua zaj duab xis rupture thiab txo coalescence. Qhov kev sim compression qhia tau hais tias, piv rau AFS, lub zog compressive thiab lub zog nqus ntawm Cf / AFS tau nce li ntawm 40.6% thiab 84.8%, feem.

Aluminium ua npuas ncauj sandwich panels tau dhau los ua neeg nyiam nyob hauv ntau qhov kev lag luam vim lawv cov khoom tshwj xeeb thiab ntau yam kev siv. Cov vaj huam sib luag no muaj cov khoom siv sib sib zog nqus (xws li txhuas ua npuas ncauj) sandwiched ntawm ob daim ntawv nyias nyias. Qhov kev tsim kho tshiab no ua rau cov khoom siv tsis yog tsuas yog hnav, tab sis kuj muaj zog, ruaj thiab corrosion-resistant. Hauv qhov blog no, peb yuav ua tib zoo saib ntawm kev siv thiab cov txiaj ntsig ntawm aluminium foam sandwich panels, thiab lawv qhov cuam tshuam rau kev lag luam sib txawv.

Tam sim no, feem ntau ntawm kev pom zoo tsim yog kom txo lub cev qhov hnyav tsis txo qhov kev ua haujlwm ntawm lub cev, nyob rau hauv ib qho xwm txheej kom nrhiav tau txoj hauv kev zoo dua ntawm kev thauj khoom, thiaj li tsim tau lub cev zoo dua qub; Nyob rau tib lub sijhawm, ntau cov ntaub ntawv tshiab thiab cov thev naus laus zis tshiab kuj pab txo qhov hnyav ntawm lub cev, tom qab ntawd, ua ke hauv qab no kom nkag siab txog qhov zoo thiab qhov tsis zoo ntawm cov khoom siv sib sib zog nqus nws!

Hlau ua npuas ncauj tau txais kev saib xyuas hauv ntau yam kev lag luam vim nws lub teeb yuag thiab lub zog muaj zog. Tuam Tshoj Beihai Composites Co., Ltd. yog ib qho ntawm cov ua lag luam ntawm cov hlau ua npuas ncauj thiab lub tuam txhab yog nyob rau hauv pem hauv ntej ntawm kev tsim cov ntaub ntawv tshiab rau ntau yam kev siv.

Hlau ua npuas ncauj yog cov khoom siv hlau nrog cov khoom tshwj xeeb, uas muaj ob qho tib si hlau thiab ua npuas ncauj, li no lub npe hlau ua npuas ncauj. Yog li, yog hlau ua npuas ncauj yog hlau?

Hlau ua npuas ncauj tau dhau los ua neeg nyiam nyob hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb thiab kev siv. Ib qho ntawm cov khoom tseem ceeb ntawm cov hlau ua npuas ncauj yog nws cov porosity, uas ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov khoom siv thiab tsim nyog rau kev siv sib txawv. Hauv qhov blog no, peb yuav ua tib zoo saib lub tswv yim ntawm porosity hauv cov hlau foams thiab tshawb xyuas qhov nws txhais tau li cas hauv ntau yam kev siv.

Copper ua npuas ncauj yog ua nthwv dej nyob rau hauv roj teeb technology vim nws cov yam ntxwv tshwj xeeb. Nws yog lub npe hu rau nws qhov chaw siab thiab zoo heev thermal thiab hluav taws xob conductivity, uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv roj teeb. Txawm li cas los xij, tseem muaj qee qhov tsis meej pem txog nws cov khoom siv hluav taws xob thiab seb nws puas yog cov khoom tsim nyog siv rau hauv cov roj teeb. Hauv qhov blog no, peb yuav tshawb xyuas cov khoom siv hluav taws xob ntawm tooj liab ua npuas ncauj thiab nws lub luag haujlwm tseem ceeb hauv kev siv roj teeb yav tom ntej.

Aluminium ua npuas ncauj yog ib qho khoom siv ntxim nyiam uas tau dhau los ua neeg nyiam nyob hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb thiab ntau yam txiaj ntsig. Los ntawm ua lub teeb yuag thiab muaj zog rau cov khoom siv thermal thiab acoustic zoo heev, aluminium ua npuas ncauj tau ua pov thawj tias yog cov khoom tseem ceeb rau ntau daim ntawv thov. Hauv tsab xov xwm no, peb yuav tshawb txog cov txiaj ntsig ntawm txhuas ua npuas ncauj thiab yuav ua li cas nws tuaj yeem hloov kho txoj kev peb tsim thiab tsim ntau yam khoom.

Ib qho ntawm cov teeb meem tseem ceeb nyob ib puag ncig tooj liab ua npuas ncauj yog nws cov conductivity, ntau yam khoom siv thiab ntau yam. Hauv qhov blog no, peb yuav tshawb txog cov khoom ntawm tooj liab ua npuas ncauj, nws cov khoom siv hluav taws xob, thiab nws cov kev siv ntau yam.
