Tungsten muaj cov yam ntxwv ntawm lub siab melting point thiab muaj zog tiv thaiv arc yaig, thaum tooj liab muaj cov hluav taws xob zoo heev thiab thermal conductivity. Kev sib xyaw ua ke ntawm tooj liab thiab tungsten ua cov khoom sib txuas tsis tsuas yog muaj kev tiv thaiv zoo rau arc yaig tab sis kuj zoo heev hluav taws xob thiab thermal conductivity. Nws yog dav siv hauv SF6 siab -voltage circuit breakers los txuas thiab txiav tam sim no. Kab lus no feem ntau yog qhia txog txoj kev npaj tshiab rau Horn Contact Wolfram cov ntaub ntawv.
Vuam hmoov, siab -purity npib tsib xee pob thiab dej muab tso rau hauv lub pob zeb rau pob zeb. Cov tungsten hmoov tom qab lub pob milling yog ua tiav qhuav, annealed, zoo li tus, pre-sintered, thiab tooj liab ntawv infiltration kho. Tom qab ntawd, cov khoom siv Tungsten Contacts tuaj yeem tau txais. Qhov sib piv ntawm txhua cov khoom siv raw thiab cov pob zeb milling tsis muaj raws li hauv qab no: qhov hnyav piv ntawm siab -purity npib tsib xee pob rau tungsten hmoov yog 4 mus rau 10: 1; tus nqi ntawm cov dej yog xam raws li 120 mus rau 150 ml ntawm dej ib 1 kg ntawm tungsten hmoov; lub sijhawm milling pob yog 12 txog 48 teev.
Lub hauv paus ntsiab lus ntawm lub pob milling txheej txheem
Los ntawm pob milling tungsten hmoov, siab -purity npib tsib xee pob thiab dej nyob rau hauv ib qho piv txwv rau ib lub sij hawm tshwj xeeb, ntawm ib sab tes, cov npib tsib xee uas hnav los ntawm qhov siab - purity npib tsib xee thaum lub sij hawm lub pob milling txheej txheem tuaj yeem ncaj qha mus rau hauv cov hmoov tungsten, ua kom tiav cov ntsiab lus ntawm cov nickel ntxiv thiab cov ntsiab lus ntawm lub pob zeb. Tungsten Contact Rivets cov khoom ntawm qhov ntsuas no yog raws nraim 0.1 txog 1.0% ntawm tag nrho qhov hnyav ntawm tungsten hmoov; Ntawm qhov tod tes, qhov nyuaj ntawm tungsten hais yog ntau dua li siab -purity npib tsib xee cov khoom, thiab lawv tuaj yeem sib cuag thiab sib tsoo, thiab cov nickel hnav los ntawm cov pob npib tsib xee tuaj yeem npog qhov sib npaug ntawm cov khoom tungsten, txhim kho cov nyhuv sintering ntawm tungsten skele.
Kev ceev faj rau txoj kev tsim khoom
Yuav kom txo tau impurity introduction, lub purity ntawm cov nickel pob yuav tsum muaj ntau tshaj los yog sib npaug zos rau 99.9%, thiab txoj kab uas hla yuav tsum yog φ6 mus rau φ30 hli;
Daim ntawv tooj liab yuav tsum tau muab tso rau hauv cov txheej txheem melting infiltration, thiab tus nqi thiab qhov sib piv ntawm daim ntawv tooj liab thiab tungsten hmoov tuaj yeem txiav txim siab raws li qhov tshwj xeeb ntawm Cov Khoom Siv Hluav Taws Xob tungsten Contact Rivets los npaj.
Qhov zoo ntawm txoj kev npaj
Nws tuaj yeem tuaj yeem ntxiv cov hmoov npib tsib xee thaum lub pob milling, thiab cov hmoov npib tsib xee tuaj yeem sib npaug hauv cov hmoov tungsten, uas ua rau cov qauv hlau tsis sib xws ntawm Tungsten Point Contact khoom, thaum muaj kev tiv thaiv zoo rau arc yaig thiab lub zog txhua yam ntawm qhov kub thiab txias.
Cov Khoom Pom Zoo
Raws li aforementioned advanced manufacturing txheej txheem, lubHorn Hu rau Wolframcov khoom peb tau tshaj tawm nruj me ntsis ua raws li cov qauv zoo rau qib siab - cov ntaub ntawv tiv tauj. Nws yog tsim los ntawm cov khoom siv tungsten zoo heev thiab muaj cov khoom zoo heev -kub tsis kam, arc yaig tsis kam, thiab conductive thiab tshav kub-cov khoom siv hluav taws xob. Cov qauv zoo ib yam thiab ruaj khov, thiab nws tuaj yeem siv rau hauv ntau yam khoom siv hluav taws xob xws li siab - cov khoom siv hluav taws xob hluav taws xob, hluav taws xob hluav taws xob, thiab cov relays. Nws tuaj yeem txhim kho kev ntseeg siab thiab kev pabcuam lub neej ntawm cov khoom siv, thiab ua tau raws li cov kev cai siv nruj ntawm kev lag luam rau kev ua haujlwm siab -kev ua tau zoo tungsten- raws li kev sib cuag.
tiv tauj peb
Peb zoo siab tos txais txhua tus neeg siv khoom tshiab thiab qub los tham txog cov khoom lag luam txhua lub sijhawm thiab tso koj daim ntawv xaj rau kev yuav khoom!
