Cov khoom siv hluav taws xob dawb tooj liab thiab hluav taws xob dawb tooj liab
Dab tsi yog cov khoom tseem ceeb ntawm hluav taws xob dawb tooj liab? Hluav taws xob cupronickel yog ib tug precision kuj alloy ua los ntawm cupronickel. Hluav taws xob dawb tooj liab muaj qhov tshwj xeeb thermoelectric zog xws li loj resistivity, me me kub coefficient ntawm tsis kam thiab loj thermal electromotive quab yuam, yog li nws yog feem ntau siv nyob rau hauv kev tsim cov khoom siv hluav taws xob!
Dab tsi yog cov khoom tseem ceeb ntawm hluav taws xob dawb tooj liab?
Hluav taws xob dawb tooj liab kuj hais txog dawb tooj liab rau precision tsis kam alloys, uas muaj zoo thermoelectric zog. BMn{{0}} manganese tooj liab, BMn40-1.5 constantan, BMn43-0.5 constantan thiab tshiab constantan siv manganese es tsis txhob npib tsib xee (tseem hu ua nickel-free manganese dawb tooj liab , muaj 10.8 ~ 12.5% manganese, 2.5 ~ 4.5% aluminium, 1.0 ~ 1.6%) yog manganese cupronickels nrog cov ntsiab lus manganese sib txawv. Manganese cupronickel yog cov hlau tsis muaj zog.
Hom alloy no muaj siab resistivity thiab tsis tshua muaj kub coefficient ntawm resistivity, thiab yog haum rau ua tus qauv kuj tivthaiv thiab precision kuj Cheebtsam. Nws yog cov khoom siv rau kev tsim cov cuab yeej hluav taws xob precision, rheostats, meters, precision resistors, strain gauges, thiab lwm yam. Constantan thiab cocoan muaj peev xwm ua kom muaj cua sov siab thiab tuaj yeem siv los ua cov thermocouples thiab cov nyiaj them poob haujlwm.
Qhov txawv ntawm tooj liab dawb thiab hluav taws xob dawb tooj liab
Cupronickel yog tooj liab-raws li alloy nrog npib tsib xee ua lub ntsiab hlau alloy. Nws tuaj yeem muab faib ua cov qauv cupronickel thiab hluav taws xob cupronickel raws li nws siv. Cov qauv tooj liab dawb (B18, B30, BZn15-20, thiab lwm yam) yog cov yam ntxwv ntawm cov khoom siv tshuab siab, kev ua haujlwm siab, tsis tshua muaj corrosion kuj, zoo weldability, thiab kub thiab txias kuj. Nws feem ntau yog siv los tsim cov khoom kub kub. thiab cov khoom ua haujlwm hauv cov xov xwm corrosive heev. Hluav taws xob dawb tooj liab (BMn40-1.5, BMn3-12, thiab lwm yam) muaj cov khoom siv hluav taws xob tshwj xeeb xws li kev tiv thaiv loj, me me kub coefficient ntawm kev ua hauj lwm thiab cov thermoelectromotive quab yuam loj, thiab yog siv dav hauv kev tsim khoom ntawm cov cuab yeej hluav taws xob.
Dawb tooj liab rau precision kuj alloys (hluav taws xob dawb tooj liab) muaj zoo thermoelectric zog. BMn{{0}} manganese tooj liab, BMn40-1.5 constantan, BMn43-0.5 constantan thiab tshiab constantan siv manganese es tsis txhob npib tsib xee (tseem hu ua nickel-free manganese dawb tooj liab , muaj 10.8 ~ 12.5% manganese, 2.5 ~ 4.5% txhuas, 1.0 ~ hlau 1.6%) yog manganese cupronickels nrog cov ntsiab lus manganese sib txawv. Manganese cupronickel yog cov hlau tsis muaj zog. Hom alloy no muaj siab resistivity thiab tsis tshua muaj kub coefficient ntawm resistivity, thiab yog haum rau ua tus qauv kuj tivthaiv thiab precision kuj Cheebtsam. Nws yog cov khoom siv rau kev tsim cov cuab yeej hluav taws xob precision, rheostats, meters, precision resistors, strain gauges, thiab lwm yam. Constantan thiab cocoan muaj peev xwm ua kom muaj cua sov siab thiab tuaj yeem siv los ua cov thermocouples thiab cov nyiaj them poob haujlwm.
Dab tsi yog cov khoom tseem ceeb ntawm hluav taws xob dawb tooj liab? Ntawm cov tooj liab alloys, tooj liab dawb muaj kev tiv thaiv corrosion zoo heev thiab yooj yim rau cov duab, txheej txheem thiab vuam. Nws yog dav siv los ua corrosion-resistant structural qhov chaw hauv nkoj tsim, roj av, tshuaj lom neeg kev lag luam, kev tsim kho, hluav taws xob fais fab, precision instruments, khoom kho mob, suab paj nruas tsim thiab lwm yam departments. . Qee cov tooj liab dawb kuj muaj cov khoom siv hluav taws xob tshwj xeeb thiab tuaj yeem siv los ua cov khoom tiv thaiv, cov khoom siv thermocouple thiab cov nyiaj them nyiaj xaim. Tsis yog kev lag luam dawb tooj liab yog siv los ua cov khoom siv dai kom zoo nkauj.
