Los ntawm sab laug, Polish tus thawj coj loj Adam Joks thiab US Army Colonel Ken Braeger hais lus thaum sawv ntawm lub tank M-1A2 Abrams uas yog ib feem ntawm Abrams Operations Summit ntawm Bucierz Range, Drawsko Pomorskie, Poland thaum Lub Plaub Hlis 28, 2022.

Muaj qhov laj thawj zoo nws yuav siv sij hawm ntau lub hlis-txawm tias qhov zoo dua ntawm ib xyoos - rau Ukraine kom tau txais thawj 31 M-1A2 Abrams tso tsheb hlau luam los ntawm Tebchaws Meskas.
Tsheb-tsim General Dynamics Land Systems yuav tsum tshem tawm cov uranium los ntawm cov tso tsheb hlau luam ces sib pauv hauv tungsten. Ob leeg hlau tuaj yeem ua teeb meem.
Nws yuav siv sij hawm rau lub hlis rau GDLS los tsim ib lub M-1A2 ntawm tsoom fwv-muaj tank Hoobkas hauv Lima, Ohio. Lub tuam txhab tsim tsuas yog peb "tshiab" tso tsheb hlau luam ib lub lim tiam, siv los ua lub hauv paus ntawm txhua tus ntawm ntau txhiab tus nyiaj seem M-1s zaum ntawm US Army arsenals. Txhua tus muaj ib tug depleted-uranium mesh nyob rau hauv lawv armor mix.
Depleted uranium yog ib qho byproduct ntawm kev lag luam nuclear. Hauv Tebchaws Meskas, nws poob rau hauv kev saib xyuas ntawm US Department of Energy - thiab raug rau DOE cov cai uas txwv tsis pub xa tawm.
Tsis yog txhua tus pom zoo rau kev xa tawm-txiav txwv yog tsim nyog. Raws li deb rov qab li xyoo 1986, US General Accounting Office-tam sim no Tsoom Fwv Teb Chaws Saib Xyuas Kev Ua Haujlwm- nug txog cov cai. "DOE yuav tsum muaj peev xwm tsim kho lub hom phiaj ntau dua uas yuav tso cai rau kev hloov pauv tau zoo dua thaum ua tau raws li cov hom phiaj tsis muaj kev vam meej," GAO khavtheeb.
Tshwj tsis yog thiab kom txog thaum cov kev cai hloov pauv, M-1 yuav tsum poob nws cov uranium depleted, thiab tau txais ib yam dab tsi los hloov nws, ua ntej US tsoom fwv yuav muag los yog pub lub tank txawv teb chaws.
Ib yam dab tsi yog tungsten. Cov hlau tawv heev uas yog tus yuam sij rau Asmeskas cov khoom xa tawm. Thaum Tebchaws Meskas muag M-1s rau nws cov phoojywg-Iraq, Saudi Arabia, Australia, Taiwan thiab Poland txhua tus yog cov neeg siv khoom tsis ntev los no-nws them GDLS, thiab tsuas GDLS, kom cov khoom tungsten rau hauv cov hlau "pockets" nyob rau pem hauv ntej ntawm M-1's turret thiab kuj, ntawm qee cov qauv, nyob rau pem hauv ntej ntawm lub hull.
Txoj haujlwm yuav siv sijhawm. Nws tsis pab tias General Dynamics Land Systems muaj kev ywj pheej ntawm kev lag luam. "GDLS tam sim no tsuas yog tus paub txog kev cog lus nrog cov cuab yeej tsim nyog ruaj ntseg thiab cov khoom tsim nyog tsim nyog muaj peev xwm txhawb nqa kev teeb tsa cov cuab yeej sib cais rau hauv Abrams lub tank sib ntaus sib tua loj," tsoomfwv Meskas tau sau tseg hauv ib qho kev txiav txim siab tsis ntev los no ntawm ib daim ntawv cog lus ib leeg rau lub tuam txhab.
Nws tsis paub meej tias tungsten-armored M-1s muaj qhov cuam tshuam rau cov yeeb ncuab hluav taws ntau dua li cov uranium-armored M-1s.
Ob leeg yog hlau heev dense, tom qab tag nrho. Hlau muaj qhov ceev ntawm ib ncig ntawm yim grams ib cubic centimeter. Uranium thiab tungsten ob qho tib si taw rau qhov ntsuas ntawm qhov hnyav 19 grams rau cubic centimeter.
Qhov tsis tau txhais hais tias koj yuav npog tag nrho lub tank hauv ob qho tib si ntawm cov xim nyiaj xim hlau. Thaum pib, ob qho tib si hlau yog nyuaj los ntawm. Depleted uranium yog ib qho khoom siv nuclear. Lub sijhawm no tungsten los ntawm cov mines me me uas ploj lawm, ntau yam nyob hauv Suav teb.
Tsis tas li ntawd, cov uranium depleted nyiam combust nyob rau hauv tej yam kev mob - thiab nws tsuas yog cov xov tooj cua thiab tshuaj lom txaus uas nws sawv cev rau kev nyab xeeb kev nyab xeeb thaum nws hlawv.
Tungsten rau nws feem yog ntom tab sis nkig. Nws zoo li tawg ntawm kev cuam tshuam. Thaum Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv Tebchaws Meskas tau tshawb xyuas tungsten txheej armor rov qab rau xyoo 1960, nws tau poob siab. "Kev siv lub ntsej muag nyuaj [tungsten] tsis zoo li qhov tsim nyog rau kev txhim kho kev ua tau zoo ntawm cov cuab yeej cuab tam," cov neeg sim qhia.
Nws tsis yog vim tsis muaj qhov laj thawj uas cov neeg tsim khoom siv armor nyiam folded depleted uranium thiab tungsten rau hauv ncuav mog qab zib zoo li armor sib tov uas. kuj suav nrog ceramics thiab hlau - thiab zoo li muaj cov hlau nyob sab nraud. Ukrainian M-1s, zoo li tag nrho cov Tsis yog-Asmeskas M-1s, yuav ua kom pom qhov no tungsten-ntawm-hauv-hauv-sab armor sib xyaw.
Lawv yuav muaj tuam txhab. Yam tsawg kawg ntawm qee qhov German tsim Leopard 2 tanks tias lub teb chaws Yelemees, Poland, Norway, Canada thiab lwm lub tebchaws tau cog lus rau Ukraine kuj muaj tungsten nyob rau hauv lawv cov armor.
