Dab tsi yog qhov txawv ntawm chromium zirconium tooj liab, alumina tooj liab thiab liab tooj liab?
Vim tooj liab muaj hluav taws xob thiab thermal conductivity, zoo heev corrosion kuj, thiab yog ib qho yooj yim rau txheej txheem thiab manufacture, nws yog dav siv nyob rau hauv niaj hnub kev lag luam. Tom ntej no, cia peb qhia luv luv txog qhov sib txawv ntawm chromium zirconium tooj liab, alumina tooj liab, thiab tooj liab liab.
Chromium Zirconium tooj liab
Chromium zirconium tooj liab yog cov khoom siv hlau nrog cov tshuaj formula ntawm CuCrZr, hardness ntawm HRB78-83, thiab conductivity ntawm 43ms / m. Chromium zirconium tooj liab muaj cov yam ntxwv ntawm cov hluav taws xob zoo, thermal conductivity, siab hardness, hnav tsis kam, tawg tsis kam, tawg tsis kam thiab kub softening.
Chromium zirconium copper (CuCrZr) is composed of three metals. It has high hardness, good wear resistance and explosion resistance, and high softening temperature (hardness>75 PAB; Tom qab khaws cia ntawm 550 degree rau 2 teev, cov dej txias txias yuav tsum tsis pub tsawg dua 15% ntawm qhov qub hardness. % lossis siab dua; qhov nruab nrab conductivity ntawm peb lub ntsiab lus ntsuas nrog ib tug eddy tam sim no conductivity meter yog ntau tshaj los yog sib npaug rau 44MS / M) thiab muaj zoo tawg kuj. Nws yog cov khoom siv vuam zoo. Cov qhab nia muaj xws li QCr1-0.15, QCr0.6-0.4, QCr0.5, C18150, C18200, thiab lwm yam.
Nws muaj zog thiab hardness, hluav taws xob thiab thermal conductivity, zoo hnav tsis kam thiab hnav-txo cov khoom. Tom qab kev laus kev kho mob, lub hardness, lub zog, hluav taws xob conductivity thiab thermal conductivity yog ho txhim kho, thiab nws yog ib qho yooj yim mus weld. Nws yog dav siv nyob rau hauv lub cev muaj zog commutators, chaw welders, seam welders, taub qab welder electrodes, thiab lwm yam uas yuav tsum tau muaj zog, hardness, conductivity, thiab conductive ncoo nyob rau hauv high kub. Lub txim hluav taws xob tuaj yeem siv los ua hluav taws xob etch ib daim iav zoo tagnrho. Nyob rau tib lub sijhawm, nws muaj kev ua tau zoo upright thiab tuaj yeem ua tiav cov teebmeem xws li thinning uas nyuaj rau kev ua tiav nrog cov ntshiab tooj liab. Nws ua tau zoo ntawm cov khoom siv nyuaj xws li tungsten steel.
Thaum lub sij hawm vuam, cov electrode poob yog me me, vuam ceev ceev, thiab tag nrho cov nqi vuam yog tsawg. Nws yog tsim nyog raws li ib tug electrode-txog yeeb nkab haum rau lub fusion vuam tshuab, tab sis nws cov kev ua tau zoo ntawm electroplated workpieces yog nruab nrab. Nws yog dav siv nyob rau hauv ntau yam ntaub ntawv rau vuam, tiv tauj cov lus qhia, hloov kev sib cuag, pwm blocks, thiab vuam tshuab auxiliary pab kiag li lawm nyob rau hauv machinery manufacturing industries xws li tsheb, maus taus, thiab chim ua (cov kaus poom).
Alumina tooj liab
Vim tias muaj txhuas oxide, aluminium oxide tooj liab tsis lo rau lub electrode thaum vuam workpieces nrog coatings (xws li zinc plating, npib tsib xee plating).
Nyob rau tib lub sijhawm, qhov kub kub softening ntawm alumina tooj liab yog li ntawm 1000 degrees, thaum lub hardness tus nqi ntawm chromium zirconium tooj liab pib poob sharply ntawm txog 400 degrees. Lub softened electrode muaj kev cuam tshuam zoo rau qhov zoo ntawm cov vuam vuam.
Alumina tooj liab (tseem hu ua dispersion-strengthened tooj liab), conductivity Ntau dua los yog sib npaug rau 80% IACS, softening kub Ntau dua los yog sib npaug rau 900 degree. Nws muaj cov khoom ntawm lub zog siab, siab conductivity thiab kub softening.
Kev sib xyaw ua haujlwm zoo hauv txhua yam, nws muaj ntau qhov chaw welds thaum lub sijhawm vuam. Thaum vuam galvanized daim hlau thiab txhuas daim hlau, lub electrode lub neej yog ob peb zaug ntev dua li cov chromium zirconium tooj liab zoo tib yam, uas txo lub sij hawm downtime los kho electrodes thiab txhim kho efficiency. Lub efficiency ntawm tsis siv neeg vuam ntau lawm kab. Thaum alumina tooj liab siv los vuam coated hlau, cov electrode tsis yooj yim deformed, tsis ua raws, muaj me me kev sib cuag sparks, tsis tig dub, muaj zoo nkauj solder pob qij txha thiab tsis muaj teeb meem dents, qhia nws superior welding kev ua tau zoo.
Tooj
Tooj liab yog ib yam khoom yooj yim ntawm tooj liab, yog li lub npe vim nws cov xim liab-liab. Liab tooj liab yog ib hom tooj liab ntshiab. Feem ntau nws tuaj yeem suav hais tias yog tooj liab ntshiab. Nws muaj cov hluav taws xob zoo conductivity thiab plasticity, tab sis tsis muaj zog thiab hardness. Nws muaj cov khoom siv hluav taws xob zoo heev, thermal conductivity, ductility thiab corrosion kuj.
Cov hluav taws xob conductivity thiab thermal conductivity ntawm tooj liab liab yog qhov thib ob tsuas yog nyiaj, thiab nws tau siv dav hauv kev ua cov khoom siv hluav taws xob thiab thermal conductive. Kev siv cov tooj liab liab yog dav dua li cov hlau ntshiab. Txhua xyoo, 50% ntawm tooj liab yog electrolytically purified rau hauv ntshiab tooj liab thiab siv nyob rau hauv kev lag luam hluav taws xob. Cov tooj liab liab hais ntawm no yuav tsum yog cov ntshiab heev, muaj ntau tshaj 99.95% tooj liab. Ib qho me me ntawm impurities, tshwj xeeb tshaj yog phosphorus, arsenic, txhuas, thiab lwm yam, yuav txo tau qhov conductivity ntawm tooj liab. Nws yog tsuas yog siv los ua cov khoom siv hluav taws xob xws li cov tshuab hluav taws xob, tsheb npav, cables, switchgear, thiab transformers, nrog rau cov khoom siv thermal conductive xws li cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob, cov kav dej, thiab cov khoom siv hluav taws xob ntawm lub hnub ci.
