• Hlau
Nickel 200 / 201 Cov yam ntxwv zoo li cas?
• Muaj peev xwm tiv taus ntau yam tshuaj txo qis
• Cov tshuaj tiv thaiv zoo heev rau alkalies alkalies
• Muaj hluav taws xob zoo hluav taws xob
• Cov tshuaj tiv thaiv zoo heev ua rau cov dej distilled thiab ntuj
• Kev tawm tsam ntawm kev daws teeb meem ntsev nruab nrab thiab alkaline
• Muaj peev xwm ua tau ntawm fluorine qhuav
• Cov khoom siv dav siv los txhawm rau quav dej qab ntsev
• Cov cua sov zoo, hluav taws xob thiab magnetostrictive zog
• Ua rau muaj qee qhov tsis kam nrog hydrochloric thiab sulfuric acids ntawm qhov ntsuas kub thiab qhov ntau
Ob Nickel 200 thiab 201 muaj kev txhim kho corrosion nyob rau hauv kev txo qis thiab nruab nrab xov xwm zoo li hauv oxidizing atmospheres tau muab rau cov xov xwm oxidizing tso cai rau kev tsim cov zaj yeeb yaj kiab oxide. No cov yeeb yaj kiab oxide tso nyiaj rau cov ntaub ntawv ua tau zoo heev hauv kev muaj peev xwm hauv thaj chaw caustic. Kev xeb nyob hauv ob qho chaw hauv hiav txwv thiab nyob deb nroog yog qhov tsawg heev. Cov ua haujlwm ntawm Nickel 200 / 201 rau xeb los ntawm dej distilled thiab ntuj yog qhov zoo heev. Ntxiv rau nws kuj tseem muab cov kev pabcuam zoo nyob rau hauv ntws hiav txwv dej txawm nyob ntawm kev nrawm, tab sis nyob rau qhov kawg lossis nrawm heev hiav txwv dej loj hauv zos nres yuav tshwm sim nyob rau hauv fouling muaj sia lossis lwm yam tso nyiaj. Hauv cov txheej txheem dej kub qhov twg lub chav muaj cov pa roj carbon dioxide thiab huab cua nyob rau hauv qee qhov feem ntau, kev xeb yuav pib thaum pib siab tab sis yuav poob qis nrog lub sijhawm yog tias cov neeg nyiam ua rau tsim cov yeeb yaj kiab tiv thaiv.
Nickel 200 feem ntau raug txwv rau kev pabcuam hauv qhov kub thiab txias hauv qab 600 ° F. Thaum kub dua Nickel 200 cov khoom lag luam tuaj yeem raug teeb meem los ntawm graphitization uas tuaj yeem ua rau muaj kev cuam tshuam loj heev. Thaum ua haujlwm kub yuav tsum siab tshaj li 600 ° F, cov ntsiab lus carbon yuav tsis zoo. Cov pa roj carbon tsawg dua ntawm Nickel 201 ua rau cov khoom tsis haum rau graphitization thiab vim li ntawd cov ntsiab lus tsawg dua embrittlement. Nickel 200 & 201 tau pom zoo rau kev tsim cov hlab ntsha siab thiab cov khoom siv hauv ASME Boiler thiab Siab Hlab Vaum Seem Code VIII, Kev faib tawm 1. Nickel 200 tau pom zoo rau kev pabcuam siab txog 600 ° F thaum Nickel 201 raug pom zoo rau kev pabcuam txog 1 230 ° F. Melting point yog 2615-2635 ° F.
