Lanthanum-cerium alloy
Khoom Description
Lanthanum-cerium alloy, tseem hu ua lub ntiaj teb tsis tshua muaj lanthanum-cerium alloy, yog cov hlau tsis tshua muaj hauv ntiaj teb lanthanum thiab cerium ua cov khoom tseem ceeb. Nws muaj lub zog siab, siab corrosion kuj, kub stability, zoo ductility thiab thermal expansion zog. Yog li ntawd, nws yog dav siv nyob rau hauv aerospace, nkoj, tsheb, electronics, tshuaj lom neeg kev lag luam thiab lwm yam teb.
Lanthanum-cerium alloys muaj ntau yam, tshwj xeeb tshaj yog nyob rau hauv lub zog siab thiab kub ib puag ncig. Nws tuaj yeem siv los ua oxide yaj electrolytic hlwb, reactors, high-temperature pipes, hydraulic thooj voos kheej kheej thiab bearings, nrog rau cov cav thiab combustion chambers rau spacecraft thiab missiles. Tsis tas li ntawd, lanthanum-cerium alloy tseem tuaj yeem siv los tsim cov tshuaj catalysts, cov khoom sib nqus, aluminium alloy thiab lwm yam khoom.
Lanthanum-cerium alloy muaj cov khoom zoo heev, nws lub zog, kev tiv thaiv corrosion, kub stability thiab zoo thermal expansion zog ua rau nws dav siv nyob rau hauv kub kub thiab phem tej yam kev mob. Nyob rau tib lub sijhawm, nws kuj yog ib qho tsis tshua muaj lub ntiaj teb alloy, yog li nws tau dav siv hauv kev ua lag luam ntawm cov ntaub ntawv tsis tshua muaj hauv ntiaj teb.
1. Txhim kho qhov zoo ntawm cov hlau: lanthanum-cerium alloy yog cov khoom siv dav siv hlau, uas tuaj yeem txhim kho cov hlau zoo, txhim kho cov tawv tawv, tawv, ductility thiab corrosion tsis kam ntawm cov hlau, kom cov hlau muaj cov khoom siv zoo dua qub thiab ua haujlwm ntev. .
2. Kev ua kom huv ntawm cov hlau: lanthanum-cerium alloy tuaj yeem txo cov ntsiab lus ntawm leej faj, phosphorus, oxygen thiab lwm yam impurities hauv cov hlau, ua lub luag haujlwm huv hauv cov txheej txheem ntawm cov hlau smelting, txhim kho cov purity ntawm cov hlau, ua kom cov hlau ntshiab dua.
3. Txhim kho roj efficiency: lanthanum-cerium alloy tuaj yeem siv los ua ib feem ntawm lub tsheb catalyst los txhim kho kev siv roj thiab kev tiv thaiv ib puag ncig ntawm lub tsheb emissions, thiab txo cov pa phem ntawm cov pa tawm mus rau ib puag ncig.
4. Rau vuam: lanthanum-cerium alloy plays lub luag haujlwm ntawm flux hauv cov txheej txheem vuam, uas tuaj yeem txhim kho qhov vuam zoo thiab ua haujlwm zoo thiab txo qhov nyuaj ntawm cov txheej txheem vuam.
5. Rau cov iav kho qhov muag: lanthanum-cerium alloy tuaj yeem siv los ua ib qho ntxiv rau cov iav kho qhov muag kom ua rau lub ntsej muag refractive, kev xa tawm thiab qhov ci ci ntawm iav, thiab txhim kho kev ua haujlwm thiab kev pab cuam lub neej ntawm cov khoom siv kho qhov muag.
Lanthanum-cerium alloy yog ib qho tseem ceeb ntawm cov khoom siv alloy, feem ntau yog siv hauv cov nram qab no:
1, hlau thiab hlau smelting: lanthanum-cerium alloy ua ib qho zoo heev deoxidizer thiab alloying tus neeg sawv cev, tuaj yeem siv dav hauv hlau thiab hlau smelting, zoo txhim kho cov hlau zoo, txo cov nqi tsim khoom.
2. Petrochemical kev lag luam: Raws li ib tug active catalyst, lanthanum-cerium alloy muaj peev xwm txhawb lub hydrocracking thiab hloov kho cov tshuaj tiv thaiv ntawm roj thiab natural gas, yog li zoo heev txhim kho cov tshuaj tiv thaiv efficiency thiab cov khoom purity.
3. Kev lag luam tsheb: Vim tias lanthanum-cerium alloy muaj qhov hnav tsis zoo, kub ruaj khov thiab oxidation tsis kam, nws yog dav siv hauv kev tsim cov tsheb cav, xws li piston, valve, intake manifold thiab lwm yam.
4. Cov ntaub ntawv sib nqus: lanthanum-cerium alloy tseem tuaj yeem siv los ua cov khoom siv hlau nplaum tseem ceeb, uas yog siv rau hauv kev sib nqus nco, lub cev muaj zog, lub tshuab hluav taws xob, sensor thiab lwm yam.
Hauv luv luv, daim ntawv thov dav ntawm lanthanum-cerium alloy tuaj yeem ua kom txoj kev loj hlob ntawm ntau lub lag luam, coj peb yooj yim dua thiab tsim kom muaj txiaj ntsig kev lag luam.
