Hlau ua npuas ncauj: Cov khoom siv hlau tshiab uas yog "muaj zog" thiab "lub teeb yuag".

Hlau ua npuas ncauj muaj cov qauv tshwj xeeb, sib txuas cov yam ntxwv ntawm cov hlau thiab cov khoom ua haujlwm ntawm cov khoom ntxeem tau. Hlau ua npuas ncauj belongs rau cov khoom siv hlau ntxeem tau, cov porosity sab hauv tuaj yeem siab li 90% lossis ntau dua, cov duab zoo li "ua npuas ncauj" lossis "honeycomb", ua txhaum lub tswv yim ntawm cov qauv ntom ntom ntawm cov hlau, ob qho tib si hlau "muaj zog" cov yam ntxwv. thiab npuas "lub teeb" yam ntxwv, yog ib tug tshiab qauv-function kev koom ua ke ntawm hlau cov ntaub ntawv. "Nws rhuav tshem lub tswv yim ib txwm muaj ntawm cov qauv ntom ntom ntawm cov hlau thiab muaj ob qho tib si cov yam ntxwv ntawm cov hlau thiab npuas, uas yog ib hom tshiab ntawm cov khoom siv hlau nrog cov qauv kev ua haujlwm. Vim nws cov qauv tshwj xeeb, cov hlau ua npuas dej tsis tsuas yog khaws cov conductivity, ductility, weldability thiab lwm yam ntxwv ntawm cov khoom siv hlau, tab sis kuj muaj cov khoom ua haujlwm ntawm cov khoom ntxeem tau, xws li lub zog nqus thiab kev co damping, txo suab nrov, electromagnetic shielding, huab cua permeability thiab dej permeability, uas tau nyiam cov neeg tuaj saib thoob plaws hauv cov ntaub ntawv tshawb fawb hauv tsev thiab txawv teb chaws thiab tau siv dav hauv kev lag luam aerospace thiab petrochemical.

Txoj hauv kev tseem ceeb los txheeb xyuas cov hlau ua npuas ncauj yog:
(1) Raws li qhov loj ntawm pore txoj kab uas hla thiab porosity: pore txoj kab uas hla tsawg dua 0.3mm, porosity ntawm 45% thiab 90%, hu ua porous hlau; thiab pore txoj kab uas hla ntawm 0.5-6mm, porosity ntau dua 90%, hu ua hlau ua npuas ncauj;
(2) Raws li tus qauv pore: nws tau muab faib ua cov qauv ntawm cov pore thiab kaw-pore qauv;
(3) Raws li cov txheej txheem kev npaj: thawj zaug npaj los ntawm txoj kev foaming yog hu ua hlau ua npuas ncauj, thiab tom qab ntawd tsim ib qho percolation casting thiab lwm txoj kev npaj tseem hu ua cua tshuab;
(4) Raws li hom matrix: txhuas ua npuas ncauj, npib tsib xee ua npuas ncauj, tooj liab ua npuas ncauj thiab lwm yam. Cov txheej txheem kev npaj, cov txheej txheem kev npaj ib txwm ua kom tau cov hlau ua npuas dej feem ntau yog cov qauv tsis sib xws, thiab 3D luam ntawv tuaj yeem tswj xyuas qhov pore qauv, raws li qhov tseeb los txhawb cov hlau ua npuas ncauj kom nthuav dav daim ntawv thov scenarios, xws li ntxeem tau titanium nyob rau hauv lub kev kho mob, precision instruments thiab lwm yam teb los ua npuas ncauj daim ntawv thov qhov khoob.

Cov qauv-kev ua haujlwm sib xyaw ua ke cov khoom siv, hlau ua npuas ncauj daim ntawv thov kev cia siab yog dav
Hlau ua npuas ncauj ua ke nrog cov qauv thiab kev ua haujlwm: raws li cov khoom siv, hlau ua npuas ncauj muaj cov yam ntxwv ntawm lub teeb yuag thiab lub zog tshwj xeeb; Raws li cov khoom siv ua haujlwm, hlau ua npuas dej muaj ntau yam khoom siv lub cev xws li ntxeem tau, kev co damping, damping, suab-absorbing, soundproofing, tshav kub dissipation, poob siab absorbing, electromagnetic shielding thiab lwm yam. Nrog nws cov khoom tshwj xeeb, hlau ua npuas ncauj tau siv dav hauv kev lag luam thiab kev ua haujlwm siab:
(1) Siv lub teeb yuag thiab cov yam ntxwv ntawm lub zog tshwj xeeb, nws yog siv los ua cov khoom siv hauv dej, cov khoom siv ua kis las (xws li sledges, thiab lwm yam), thiab cov khoom siv ntawm cov tsheb hauv aerospace;
(2) Kev siv cov ntxeem tau, nrog kev tsim cov tshuaj lim dej, rau kev ua kom huv ntawm cov dej siv hauv cov txheej txheem gasification, tsis siv neeg refueling ntawm cov roj bearings, scented decorations, thiab lwm yam.;
(3) kev siv cov kev vibration damping, damping kev ua tau zoo, nrog rau nws cov khoom siv raws li qhov tsis zoo, kev co absorber, xws li kev tsaws iav ntawm lub dav hlau, elevator kis tau tus mob kev nyab xeeb cushions thiab ntau lub thawv, tshwj xeeb tshaj yog cov thawv thauj huab cua, cov cuab yeej siv lub txaj, bases, damping rings, thiab lwm yam;
(4) Kev siv nws cov hluav taws xob tiv thaiv hluav taws xob, lub teeb yuag thiab lub suab zoo heev, lub suab rwb thaiv tsev, tau siv los ua kev lag luam kev lag luam suab rwb thaiv tsev panels, hluav taws xob cov cuab yeej plhaub thiab hluav taws xob tiv thaiv chav tsev.

Hauv cov ntaub ntawv tshwj xeeb, cov hlau ua npuas dej yog dav siv hauv txhuas, npib tsib xee, tooj liab thiab nws cov alloys, cov yam ntxwv tseem ceeb ntawm cov khoom sib txawv matrix thiab daim ntawv thov sib txawv.
(1) Aluminium ua npuas ncauj: Raws li qhov ntxov tshaj plaws tsim ua npuas ncauj hlau cov ntaub ntawv, lub ntsiab kom zoo dua ntawm txhuas ua npuas ncauj nyob rau hauv lub teeb yuag, tshav kub rwb thaiv tsev, suab rwb thaiv tsev, electromagnetic shielding, nqus lub zog, thiab lwm yam., uas yog siv nyob rau hauv cov kev tiv thaiv txheej. ntawm missiles, aircraft thiab lawv cov recycled qhov chaw, thiab kuj yog siv nyob rau hauv lub teb ntawm tsheb tsis, hluav taws xob thiab mechanical vibration damping ntaus ntawv, electromagnetic yoj shielding npog ntawm lub hwj chim mov hauv cov mem tes, thiab lwm yam;
