1. Peb lub Hoobkas nyob hauv Luoyang City, Henan Province. Luoyang yog thaj chaw tsim khoom rau tungsten thiab molybdenum mines, yog li peb muaj qhov zoo ntawm qhov zoo thiab tus nqi;
2. Peb lub tuam txhab muaj cov kws tshaj lij nrog ntau tshaj 15 xyoo kev paub, thiab peb muab cov kev daws teeb meem thiab cov lus qhia rau txhua tus neeg siv khoom xav tau.
3. Tag nrho peb cov khoom raug soj ntsuam nruj ua ntej xa tawm.
4. Yog tias koj tau txais cov khoom tsis raug, koj tuaj yeem tiv tauj peb kom them rov qab.
1. Kev npaj khoom siv

3. Daim ntawv thov ntawm tungsten rods nyob rau hauv lub tshav pob ntawm electronics: Vim lawv zoo heev conductivity thiab thermal stability, tungsten rods kuj muaj ib tug tseem ceeb daim ntaub ntawv nyob rau hauv lub tshav pob ntawm electronics. Tungsten rods tuaj yeem siv los tsim cov khoom siv semiconductor, electrodes, thiab emitters.
1. Thermal stress: Thaum lub tungsten pas nrig yog rhuab mus rau qhov kub siab, nws yuav raug thermal stress, uas yuav ua rau nws khoov los yog warp. Qhov no tuaj yeem tshwm sim yog tias tus pas nrig tsis tau txais kev txhawb nqa zoo lossis raug hloov pauv sai.
2. Cov khoom siv qaug zog: Tungsten rods yuav muaj kev qaug zog ntawm cov khoom siv tom qab siv qhov kub thiab txias rau lub sijhawm ntev. Qhov no tuaj yeem ua rau cov khoom tsis muaj zog, ua rau nws yooj yim rau khoov lossis warp.
3. Kev ua kom txias tsis txaus: Yog tias tus pas nrig tungsten tsis ua kom txias zoo tom qab siv, cov cua sov tuaj yeem khaws cia thiab txuas ntxiv mus rau deform thaum lub caij txias, ua rau khoov.
4. Mechanical puas tsuaj: Yog hais tias tus pas nrig tungsten raug rau cov neeg kho tshuab kev ntxhov siab lossis cuam tshuam thaum siv, micro-cracks lossis lwm yam kev puas tsuaj tuaj yeem tshwm sim, uas ua rau khoov tom qab hlawv.
1. Xaiv qhov tsim nyog tungsten pas nrig
Xaiv cov khoom tsim nyog thiab cov lus qhia tshwj xeeb thaum siv tungsten rods. Cov xwm txheej sib txawv yuav tsum tau siv cov kev qhia tshwj xeeb thiab qhov ntev ntawm tungsten rods.
2. Tswj qhov kub thiab txias
Thaum cua sov tungsten rods, nws yog ib qho tseem ceeb uas yuav tsum tswj qhov kub thiab txias rau lub sij hawm cua sov kom tsis txhob muaj qhov kub thiab txias heev los yog lub sij hawm cua sov ntev.
3. Tsis txhob ncab ntau dhau
Thaum siv cov tungsten rods, yuav tsum tau zam kev ncab ntau dhau, thiab hloov txoj kev vuam los yog lwm yam txheej txheem tuaj yeem txiav txim siab.
