Cov khoom siv aluminium tshiab yog ib hom tshiab ntawm cov khoom siv hlau uas siv cov txheej txheem tshwj xeeb los sau cov npuas rau hauv cov txhuas yaj, thiab siv cov txheej txheem tsim nyog los khaws cov npuas hauv cov yaj los ua cov qauv roj-cov khoom sib xyaw los ntawm kev ua kom txias. Raws li cov txheej txheem sib txawv ntawm cov roj filling, cov ntaub ntawv tshiab txhuas ua npuas ncauj tuaj yeem muab faib ua cov xov tooj ntawm tes kaw thiab qhib-cell aluminium ua npuas ncauj. Qhov kev ua tau zoo ntawm cov khoom siv ua npuas ncauj tshiab feem ntau yog nyob ntawm nws qhov pore qauv tsis xws li porosity, pore txoj kab uas hla, los ntawm porosity, pore hom, qhov chaw tshwj xeeb, thiab lwm yam, thiab nws qhov pore qauv tsis yog nyob ntawm cov txheej txheem kev npaj. Yog li ntawd, kev npaj technology ntawm txhuas ua npuas ncauj tau dhau los ua kev tshawb fawb hotspot nyob rau hauv cov ntaub ntawv tshiab.
Muaj ntau cov txheej txheem kev npaj rau cov ntaub ntawv tshiab txhuas ua npuas ncauj, thiab cov khoom lag luam tseem ceeb ntawm cov ntaub ntawv txhuas ua npuas ncauj tshiab yog qhov tseem ceeb hauv: yaj foaming txoj kev, yaj tshuab txoj kev thiab hmoov metallurgy txoj kev:
1. Kev npaj ntawm cov ntaub ntawv tshiab aluminium ua npuas ncauj los ntawm yaj foaming txoj kev yog muab faib ua smelting, yaj pretreatment, yaj viscosity nce, additive stirring, thermal rwb thaiv tsev foaming, txias, txiav, ntawv tom qab ua, cia, ntim thiab lwm yam txheej txheem. Txhua txoj kev siv cov khoom siv hlau tsis muaj tshuaj lom thiab tsis muaj mob, uas tuaj yeem paub txog 100% rov ua dua ntawm cov khoom pov tseg thiab cov khoom siv rov ua dua tshiab.
2. hmoov metallurgy yog sib tov aluminium hmoov thiab foaming agent hmoov thiab compress kom tau ib tug preform nrog ib tug airtight qauv. Thaum tshav kub kub lub preform kom decompose tus neeg sawv cev foaming tso pa roj, yuam lub preform nthuav kom tau foamed aluminium. Piv nrog rau lwm txoj kev, cov hmoov hlau metallurgy txoj kev tuaj yeem siv ntau yam ntawm cov khoom siv hlau, uas yog qhov zoo los txhim kho cov khoom siv ntawm cov ntaub ntawv aluminium tshiab, thiab tuaj yeem ncaj qha tsim cov khoom nrog cov duab nyuaj.
3. Cov txheej txheem yaj yaj yog thawj zaug ntxiv SiC, Al2O3, thiab lwm yam rau cov hlau molten, thiab disperse nws uniformly kom lub viscosity ntawm yaj, thiab ces tshuab roj (xws li nitrogen, inert gas, thiab lwm yam) rau lub hauv qab ntawm cov hlau molten, nyob rau hauv cov hlau molten Tom qab tsim ib tug loj tus naj npawb ntawm pores, nws txias thiab solidifies. Cov txheej txheem yaj tshuab tuaj yeem paub qhov kev npaj tas mus li ntawm cov ntaub ntawv txhuas ua npuas ncauj tshiab, nrog cov khoom siv yooj yim, tus nqi qis, thiab cov khoom tswj tau qhov porosity.
