Tungsten Export Controls tsis yog tag nrho txwv
tungsten export tswj tsis tau hais txog tag nrho cov kev txwv tsis pub xa tawm tab sis koom nrog kev tswj hwm tus qauv rau cov khoom tshwj xeeb tungsten. Cov neeg xa tawm ntawm cov khoom no yuav tsum tau thov kev tso cai los ntawm cov kws tshaj lij kev lag luam ntawm Lub Xeev Pawg Saib Xyuas Kev Lag Luam raws li Txoj Cai Tswjfwm Nthuav Tawm thiab Cov Txheej Txheem ntawm Kev Tswj Xyuas Kev Tshaj Tawm ntawm Cov Khoom Siv Dual. Kev xa tawm tsuas yog tso cai raws li kev ua raws cai thiab kev pom zoo.
Muaj peev xwm cuam tshuam rau Kev Lag Luam Hauv Tsev
Raws li cov ntaub ntawv los ntawm Tungsten-Molybdenum Huab Kev Lag Luam Platform, kev xa tawm ntawm ammonium paratungstate (APT), tungsten trioxide, thiab tungsten carbide account rau ib qho tseem ceeb ntawm tag nrho tungsten xa tawm:
- APT xa tawm hauv 2023 thiab 2024 yog kwv yees li 803 tons thiab 782 tons, raws li, txhua tus accounting txog li 4% ntawm tag nrho cov tungsten xa tawm.
- Tungsten trioxide xa tawm yog kwv yees li 2,699 tons hauv 2023 thiab 3,190 tons hauv 2024, nce ntawm 14% mus rau 17% ntawm tag nrho cov khoom xa tawm.
- Tungsten carbide xa tawm yog kwv yees li 4,433 tons hauv 2023 thiab 4,147 tons hauv 2024, tuav ib feem ntawm kwv yees li 22%.
Kev siv ntawm tungsten export tswj yuav ua rau cov khoom no nruj me ntsis saib xyuas thiab pom zoo cov txheej txheem, muaj feem cuam tshuam rau qee qhov kev lag luam xa tawm. Txawm li cas los xij, muab qhov txwv tsis pub tshaj ntawm cov khoom tswj hwm hauv tag nrho cov khoom xa tawm tungsten, tag nrho cov cuam tshuam rau kev lag luam tungsten hauv tsev cov khoom siv-xav tau zoo thiab cov nqi sib txawv yuav tsum yog tsawg. Txoj cai no kuj tseem yuav txhawb kom cov tuam txhab tsom mus rau kev tsim kho thev naus laus zis thiab cov khoom lag luam zoo kom ua tau raws li kev xav tau ntawm kev lag luam hauv tsev thiab thoob ntiaj teb.
Lub tswv yim tseem ceeb ntawm tungsten
Tungsten lub siab melting point, hardness, conductivity, thiab corrosion kuj ua rau nws indispensable nyob rau hauv lub ntiaj teb no kev lag luam. Hauv kev tsim cov hlau, tungsten txhim kho lub zog, toughness, thiab hnav tsis kam, dav siv hauv tshuab thiab kev tsim kho. Hauv cov khoom siv hluav taws xob, nws yog cov khoom siv tseem ceeb rau cov khoom siv, cov khoom siv hluav taws xob sib txuas, thiab cov filaments ib txwm muaj. Nyob rau hauv aerospace, tungsten alloys yog ib qho tseem ceeb rau cov cav tov thiab foob pob ua ntxaij nozzles, txhawb kev tshawb nrhiav chaw. Tub rog, tungsten alloys yog qhov tseem ceeb rau cov cuab yeej cuab yeej cuab tam, cov khoom siv foob pob hluav taws, thiab cov cuab yeej cuab tam, cuam tshuam ncaj qha rau kev tiv thaiv lub tebchaws. Ua kom muaj kev ruaj ntseg hauv tsev tungsten yog qhov tseem ceeb rau kev ruaj ntseg hauv tebchaws.
Kev cuam tshuam luv luv thiab ntev
Nyob rau lub sijhawm luv luv, kev tswj hwm kev xa tawm yuav txo qis Tuam Tshoj cov khoom siv tungsten rau kev lag luam thoob ntiaj teb, muaj peev xwm cuam tshuam qhov kev xav tau ntawm cov khoom siv ntev ntev thiab tsav tsheb thoob ntiaj teb cov nqi tungsten nce siab vim qhov kev thov qis qis. Nyob rau lub sijhawm ntev, cov kev tswj xyuas no yuav txhawb kev txhim kho kev lag luam, txhawb R & D kev nqis peev, kev siv peev txheej zoo, thiab kev tsim cov khoom muaj txiaj ntsig zoo los txhim kho Tuam Tshoj txoj kev cuam tshuam hauv kev lag luam tungsten.
Ntiaj teb no Tungsten Statistics
Raws li USGS, thoob ntiaj teb tungsten reserves nyob rau hauv 2023 yog kwv yees li 4.4 lab tons, nce 15.79% xyoo-rau-xyoo, nrog Tuam Tshoj accounting rau 52.27% (2.3 lab tons). Ntiaj teb no tungsten ntau lawm yog 78,000 tons, nqis 2.26%, nrog Tuam Tshoj pab 80.77% (63,000 tons). Suav cov ntaub ntawv kev lis kev cai qhia txog ntau yam tungsten xa tawm, suav nrog tungsten ores, tungstic acid, tungsten trioxide, tungsten carbides, thiab ntau yam khoom tungsten. Xyoo 2024, Tuam Tshoj tau xa tawm 782.41 tons ntawm APT (qis 2.53%, 4.06% ntawm tag nrho cov khoom xa tawm), 3,189.96 tons ntawm tungsten trioxide (nce 18.19%, 16.55% ntawm tag nrho cov khoom xa tawm), thiab 4,146.76 tons ntawm tungsten 5% ntawm tag nrho 2.6% carb. exports).
