tungsten muaj qhov kub siab tshaj plaws melting point, yog li nws yuav yaj tsuas yog thaum muaj cov nqi hluav taws xob ntau dhau los ntawm lub voj voog. Tab sis rau qis qis ntawm tam sim no uas tseem yuav ua rau muaj kev phom sij rau cov khoom siv yuav tsis raug txiav tawm los ntawm tungsten fuse. Yog li nws tsis tuaj yeem siv rau hauv fuse hlau.
Vim li cas tungsten tsis siv los ua fuse hlau chav kawm 10?
tungsten tsis yog siv los ua fuse xaim vim nws muaj lub siab melting pointthiab yog tias peb siv nws qhov tseeb lub fuse yuav tsis ua haujlwm thiab nyob rau hauv cov ntaub ntawv ntawm high voltage lub qhov muag teev thiab Cov khoom siv yuav tau fused.
Vim li cas tungsten siv hauv xaim?
Tungsten hlau yog siv los ua cov cua sov hlau vim tsuas yog tungsten muaj qhov melting point ntau tshaj 3,400 degrees Celsius, uas yog qhov siab tshaj plaws melting point ntawm cov hlau, nrog rau qhov kub thiab txias tsis kam, corrosion kuj, thermal expansion coefficient tsawg, zoo winding kev ua tau zoo, tsis sagging thiab lwm yam …
Vim li cas tungsten hlau tsis siv hauv fuse hlau tab sis lub teeb?
Tungsten yog cov hlau uas nws cov ntsiab lus melting siab heev. Nws yog siv nyob rau hauv qhov muag teev vim hais tias tungsten yuav tsis ntes hluav taws nyob rau hauv lub teeb. Tab sis nws tsis yog siv nyob rau hauv fuse xov tooj vim fuse xov hlau xav tau ib qho qis melting point. … Fuse hlau yuav tsum muaj qhov qis melting, thaum dhau tam sim no ntws, cov hlau melts thiab Circuit Court tawg.
Vim li cas Nichrome tsis siv hauv qhov muag?
Nichrome hlau, ib qho hlau ntawm nickel thiab chromium, thiab feem ntau hlau (los yog lwm yam khoom)yog qhov zoo rau kev ua cov cua sov tab sis tsis yog lub teeb. Ntawm qhov ntsuas voltages, nichrome yuav ci txiv kab ntxwv-liab, tsis yog lub ci dawb uas xav tau rau kev teeb pom kev zoo. Yog tias koj nce qhov hluav taws xob kom tau txais cov xim ci dua, lub nichrome yuav kub hnyiab (kub.)
