abstract
Niaj hnub no, cov khoom siv hluav taws xob muaj nyob txhua qhov chaw hauv peb lub neej, thiab tus yuam sij rau lawv txoj kev ntseeg siab thiab kev ua tau zoo nyob hauv ib qho me me -tungsten tiv tauj. Nyob rau hauv lub ntiaj teb no ntawm cov khoom siv hluav taws xob, tungsten kev sib cuag yog ua ib tug kiv puag ncig, coj peb ib tug ntau txhim khu kev qha thiab zoo hluav taws xob kev.
Khoom Description
Tungsten tiv tauj hauv cov khoom siv hluav taws xob tsis yog tsuas yog cov ntsiab lus sib cuag tab sis kuj yog cov neeg saib xyuas tam sim no. High-purity tungsten hu tau txais kev hwm rau lawv cov khoom zoo: cov khoom zoo xws li cov ntsiab lus siab melting, qis evaporation tus nqi, thiab cov hluav taws xob zoo thiab thermal conductivity ua rau lawv cov khoom muaj nqis hauv cov khoom siv hluav taws xob.
Piv nrog rau cov ntsiab lus kev sib cuag, tungsten kev sib cuag muaj cov txiaj ntsig zoo hauv lub neej voj voog. Nws qhov kev ua tau zoo ruaj khov ua rau lub voj voog ib txwm muaj kev sib cuag zoo, thiab yuav tsis muaj kev ua haujlwm tsis zoo vim kev hloov pauv ntau zaus. Qhov no txhais tau hais tias kev ruaj ntseg thiab kev pab cuam lub neej ntawm cov khoom siv hluav taws xob tau txhim kho zoo heev.
Niaj hnub tswj cov khoom siv hluav taws xob, xws liAC contactors, electromagnetic relays, hluav taws xob hloov hluav taws xob, thiab lwm yam., txhua tus cia siab rau cov khoom siv hluav taws xob zoo. Tungsten tiv tauj tsis yog tsuas yog ua tau raws li cov kev cai nruj ntawm cov khoom siv hluav taws xob rau kev sib cuag tab sis kuj tuaj yeem tiv nrog ntau qhov chaw ua haujlwm thiab ntau zaus kom ntseeg tau tias cov cuab yeej ua haujlwm ruaj khov.
Arcing yog ib qho teeb meem tshwm sim hauv kev siv cov khoom siv hluav taws xob, uas tuaj yeem ua rau kev ua haujlwm tsis zoo, kev sib cuag tsis ua haujlwm, thiab txawm tias hluav taws kub ntawm cov khoom siv cuam tshuam. Tungsten hu, nrog rau lawv superior corrosion kuj thiab siab melting point, zoo daws cov teeb meem arcing thiab xyuas kom ruaj khov ntawm cov khoom siv hluav taws xob.
Cov ntsiab lus
Nyob rau hauv lub tshav pob ntawm cov khoom siv hluav taws xob, nruam innovation yog tsav cov kev kawm ntawm cov khoom siv. Raws li ib qho ntawm cov kev tsim kho tshiab, tungsten kev sib cuag tau ua rau lub sijhawm tuaj txog ntawm cov khoom siv hluav taws xob tshiab. Nyob rau lub sijhawm no, peb tuaj yeem siv cov khoom siv hluav taws xob muaj kev ntseeg siab thiab txaus siab rau qhov yooj yim coj los ntawm cov khoom siv hluav taws xob zoo thiab muaj txiaj ntsig zoo.
