Hlau Foams Kev Lag Luam Daim Ntawv Thov Scope thiab Kev Pom Zoo
Hlau ua npuas ncauj yog cov khoom siv hlau hollow tsim los ntawm cov txheej txheem hlau tshwj xeeb, yog li nws muaj zog toughness, hnav, siab tawv hardness, tsis tshua muaj suab nrov, zoo thermal rwb thaiv tsev, thiab lwm yam khoom zoo heev. Tam sim no, daim ntawv thov ntawm cov hlau ua npuas ncauj tau dav thiab dav, dav siv nyob rau hauv ntau yam teb, muaj peev xwm dav thiab muaj kev vam meej yav tom ntej.
Hlau ua npuas ncauj | R & D ntawm Ballistic Protection Systems rau Kev Ua Tsov Rog Niaj Hnub No
Nyob rau hauv lub xyoo pua 21st, nrog cov cuab yeej ua tub rog nce zuj zus, kev ua txhaum cai thiab kev tiv thaiv yuav tsum vam khom rau kev tshawb fawb, muaj zog thiab hnav lub cev armor systems ( kaus mom hlau, ris tsho hauv qab, lub xub pwg nyom, lub ntsej muag lub ntsej muag) kom txwv tsis pub lawv tus kheej los ntawm kev hloov mus rau hauv cov phom loj.
Lub cev armor yog dab tsi uas muaj kev nyab xeeb dua tam sim no uas cov cuab yeej siv tub rog tau nce siab? Qhov tseeb kev tawg yog cov mos txwv undershirts ua nrog cov hlau ua npuas ncauj uas tuaj yeem ua rau cov mos txwv ya zoo siab.
Nws tsis yog ib qho hlau xwb, tab sis yog tsim los ntawm melting aluminium nyob ib ncig ntawm lub pob hlau hollow. Cov hlau ua npuas dej sib xyaw yog ntau dua 70% sib zog dua li cov ntawv hlau tsis tu ncua - thiab nqus tau 80 npaug ntau dua li cov hlau. Lub cev armor yog ua los ntawm cov hlau sib xyaw ua npuas ncauj thiab boron carbide ceramic, thaum lub phaj nraub qaum yog Kevlar.
Daim ntawv thov ntawm Nickel Foam ntawm AEM Hydrogen Generation Electrolyzer
Nickel ua npuas ncauj yog ib qho permeable heev, tsawg-density, peb-dimensional reticulated ua npuas ncauj hlau cov ntaub ntawv, uas yog ib tug tshiab thiab sai tsim cov ntaub ntawv nyob rau hauv tam sim no cov ntaub ntawv kev tshawb fawb. Cov qauv ua npuas dej muab cov nickel hlau ib qho qhib-hlwb qauv, uas muab nws zoo heev permeability thiab tseem ceeb hloov tshav kub thiab dissipation zog.
Nickel ua npuas ncauj yog tsim los ntawm electroplating rau ntawm lub cev pob txha ntawm cov polymers tshwj xeeb nrog peb-seem network qauv, xws li polyurethane, polyester polyurethane thiab lwm yam tshwj xeeb polymers (sponges). Tom qab plating, cov khoom ua npuas dej kawg yog tsim los ntawm kev hlawv tawm ntawm cov khoom siv polymer sab hauv thiab txo cov hlau oxides, thiab yog mechanically shaped los ntawm kev kho cua sov.
Nickel ua npuas ncauj, nrog nws lub teeb yuag thiab cov khoom siv hluav taws xob, yog ib lub tsev tseem ceeb ntawm AEM's hydrogen electrolyzers, muab cov kev daws teeb meem zoo tshaj plaws rau kev tsim hluav taws xob zoo thiab muaj txiaj ntsig zoo.
