Tungsten yog ntxiv rau hlau rau ntau yam laj thawj:

1. Ua kom muaj zog: Tungsten nce qhov hardness thiab hnav tsis kam ntawm cov hlau, ua rau nws tsim nyog rau cov ntawv thov uas cov hlau yuav tsum tau tiv taus siab hnav thiab tsim kua muag.

2. Txhim kho lub zog: Tungsten pab ua kom lub zog thiab lub zog ntawm cov hlau, ua rau nws tsim nyog siv rau hauv cov ntawv thov kev ntxhov siab xws li cov cuab yeej txiav, laum cov khoom thiab cov hlau kub ceev.

3. Kev ruaj ntseg kub kub: Tungsten pab txhim kho qhov kub thiab txias stability ntawm steel, ua rau nws haum rau cov kev siv uas steel xav tau kev tswj nws cov neeg kho tshuab zog ntawm qhov kub thiab txias.

Zuag qhia tag nrho, qhov sib ntxiv ntawm tungsten rau hlau txhim kho nws cov khoom tag nrho, ua rau nws tsim nyog rau ntau yam kev lag luam.

Tungsten daim hlauyog siv nyob rau hauv ntau daim ntawv thov kev lag luam vim nws cov khoom tshwj xeeb. Qee qhov kev siv rau tungsten phaj suav nrog:

1. Radiation shielding: Vim yog tungsten lub siab ceev thiab muaj peev xwm nqus tau hluav taws xob, tungsten daim hlau yog siv los tiv thaiv hluav taws xob hauv kev kho mob thiab kev lag luam ib puag ncig.

2. High-temperature furnace Cheebtsam: Vim nws lub siab melting point thiab kub tsis kam, tungsten daim hlau yog siv los tsim high-temperature furnaces thiab cua sov ntsiab.

3. Aerospace thiab tiv thaiv daim ntawv thov: tungsten daim hlau yog siv nyob rau hauv aerospace thiab tiv thaiv kev lag luam rau cov khoom uas yuav tsum tau muaj zog, hardness thiab kub tsis kam.

4. Hluav taws xob tiv tauj: Vim nws cov conductivity siab thiab tsis kam mus rau arc yaig, tungsten daim hlau yog siv rau hluav taws xob tiv tauj thiab electrodes.

5. Thaum tshav kub kub dab dej: Vim lub siab thermal conductivity ntawm tungsten, tungsten daim hlau yog siv los ua cov dab dej kub hauv kev siv hluav taws xob thiab semiconductor.

Zuag qhia tag nrho, cov paib tungsten tau muaj nuj nqis rau lawv lub siab ntom ntom, ua rau muaj kev sib haum xeeb, ua rau lawv haum rau ntau yam kev siv khoom lag luam thiab kev lag luam.

Tungsten suav hais tias tsis muaj kev nyab xeeb rau kev sib cuag nrog zaub mov. Tungsten yog cov hlau hnyav thiab thaum nws muaj ntau daim ntawv thov kev lag luam vim nws cov khoom tshwj xeeb, nws tsis tsim nyog siv rau hauv cov khoom noj khoom haus lossis cov khoom sib cuag. Kev noj tungsten tuaj yeem ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv, vim tias ntau dhau ntawm tungsten thiab lwm yam hlau hnyav tuaj yeem ua rau muaj teeb meem kev noj qab haus huv ntau.

Yog li ntawd, nws yog ib qho tseem ceeb los xyuas kom meej tias tungsten lossis tungsten-muaj cov ntaub ntawv tsis tuaj yeem nkag mus rau hauv cov khoom noj los yog cov khoom noj khoom haus. Cov koom haum tswj hwm xws li US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA) muaj cov lus qhia thiab cov kev cai nruj me ntsis kom ntseeg tau tias muaj kev nyab xeeb ntawm cov khoom uas tuaj yeem cuam tshuam nrog zaub mov.
