Kev siv tseem ceeb ntawm Beryllium yog dab tsi?

Beryllium muaj peev xwm tshaj plaws los xa cov X-rays thiab hu ua "hlau iav".Nws cov alloys yog irreplaceable cov tswv yim hlau cov ntaub ntawv nyob rau hauv aviation, aerospace, tub rog, electronics, nuclear zog thiab lwm yam teb.Beryllium bronze yog ib qho elastic alloy nrog kev ua tau zoo tshaj plaws ntawm cov tooj liab alloys.Nws muaj qhov zoo ntawm thermal conductivity, hluav taws xob conductivity, tshav kub tsis kam, hnav tsis kam, corrosion kuj, tsis-sib nqus, me elastic lag, thiab tsis muaj sparks thaum cuam tshuam.Nws yog dav siv hauv kev tiv thaiv lub teb chaws, Cov Khoom Siv, cov twj paj nruag, khoos phis tawj, tsheb, khoom siv hauv tsev thiab lwm yam lag luam.Beryllium-tooj ​​liab-tin alloys yog siv los tsim cov springs uas ua haujlwm ntawm qhov kub thiab txias, uas tswj tau zoo elasticity thiab toughness nyob rau hauv liab kub, thiab beryllium oxide yuav siv tau raws li tshav kub-resistant fillers rau high-temperature thermocouples.

Thaum pib, vim tias cov tshuab smelting tsis yog raws li tus qauv, cov smelted beryllium muaj impurities, uas yog nkig, nyuaj rau txheej txheem, thiab yooj yim rau oxidize thaum rhuab.Yog li ntawd, ib qho me me ntawm beryllium tsuas yog siv tau rau hauv cov xwm txheej tshwj xeeb, xws li siv hauv X-ray raj.Lub teeb-hloov cov qhov rais me me, qhov chaw ntawm lub teeb neon, thiab lwm yam. Tom qab ntawd, daim ntawv thov ntawm beryllium tshwm nyob rau hauv dav thiab tseem ceeb ntawm cov teb tshiab - tshwj xeeb tshaj yog cov tsim ntawm beryllium tooj liab alloy - beryllium bronze.
Raws li peb txhua tus paub, tooj liab yog softer dua hlau, thiab nws elasticity thiab tsis kam mus corrosion tsis muaj zog.Tab sis tom qab ntxiv qee qhov beryllium rau tooj liab, tooj liab cov khoom hloov pauv loj heev.Tshwj xeeb, beryllium bronze muaj 1 txog 3.5 feem pua ​​​​ntawm beryllium muaj cov khoom siv zoo heev, txhim kho hardness, zoo elasticity, siab corrosion kuj, thiab hluav taws xob conductivity.Tshwj xeeb, cov springs ua los ntawm beryllium bronze tuaj yeem compressed ntau pua lab zaus.

Lub indomitable beryllium bronze yog siv los tsim cov kev sojntsuam hauv hiav txwv tob thiab submarine cables, uas yog qhov tseem ceeb heev rau kev tsim cov peev txheej marine.Lwm qhov tseem ceeb ntawm npib tsib xee-muaj beryllium bronze yog tias nws tsis muaj teeb meem thaum ntaus.Yog li ntawd, qhov no feature yog heev pab tau rau explosives factories.Vim tias cov khoom siv hluav taws xob thiab cov khoom tawg tau ntshai heev ntawm hluav taws, xws li cov khoom tawg thiab cov detonators, lawv yuav tawg thaum lawv pom hluav taws.Hlau hammers, xyaum thiab lwm yam cuab yeej feem ntau emit sparks thaum lawv siv, uas yog heev txaus ntshai.Undoubtedly, nickel-muaj beryllium bronze yog cov khoom tsim nyog tshaj plaws los ua cov cuab yeej no.

Nickel-muaj beryllium bronze tsis nyiam cov hlau nplaum thiab tsis yog magnetized los ntawm magnetic teb, ua rau nws yog ib qho khoom zoo heev rau cov hlau nplaum tiv thaiv qhov chaw.Tsis tas li ntawd, nyob rau hauv xyoo tsis ntev los no, beryllium, uas muaj ib tug me me lub ntiajteb txawj nqus, siab zog thiab zoo elasticity, tau siv los ua ib daim iav rau high-precision TV faxing, thiab cov nyhuv yog zoo heev, vim hais tias nws tsuas siv sij hawm ob peb feeb. xa ib daim duab.

Beryllium tau tsis paub "tus neeg me" hauv cov peev txheej tau ntev, thiab tsis tau txais kev saib xyuas ntau los ntawm tib neeg.Tab sis nyob rau xyoo 1950, beryllium cov peev txheej tau tig mus thiab dhau los ua cov khoom kub rau cov kws tshawb fawb.

Txhawm rau kom tso tawm ntau lub zog los ntawm lub nucleus, cov kws tshawb fawb yuav tsum tau foob pob hluav taws xob nrog lub zog loj, kom lub nucleus sib cais, ib yam li kev foob pob hluav taws tawg nrog cov phom phom thiab ua rau lub foob pob tawg.Lub "cannonball" siv los tua cov nucleus hu ua neutron, thiab beryllium yog ib qho zoo heev "neutron source" uas tuaj yeem muab ntau cov neutron cannonballs.Hauv atomic boiler, tsuas yog neutrons "ignite" tsis txaus.Tom qab ignition, nws yog tsim nyog los ua kom nws tiag tiag "hluav taws thiab hlawv".
