1.What yog alloy b?
Txhais ntawm alloy b: Alloy B yog ib lo lus dav dav rau ib hom Nickel - Molybdenum alloys. Nws cov xeeb ceem tseem ceeb yog nws cov zog tiv thaiv kom txo qis acid corrosion, thiab nws tuaj yeem ua kom muaj kev ua tau zoo hauv ib puag ncig xws li hydrochloric acid thiab sulfuric acid. Tus sawv cev raug yog hastellloy b alloy, uas yog dav siv hauv kev lag luam tshuaj thiab lwm daim teb.
2.What yog hastellloy b3?
Hastelloy b3 yog ib qho Austenic Ni - Mo alloy nrog Asme Qib N10675. Nws nominal muaj pes tsawg leeg yog 65ni - 29. 5mo - 2 fe 1. Nws tau ua tau zoo heev rau hydrochloric acid acid corrosion ntawm ntau yam kev ua thiab muaj cov sulphion acid, accic acid, formic acid, thiab phosphoric acid. Nws yog npib tsib xee - raws li siab - qhov kub thiab yog cov khoom siv tshiab, thiab yog cov khoom siv tshiab txhim kho ntawm Hastelloy B2. Nws txhim kho lub thermal ruaj thiab corrosion tsis kam ntawm cov khoom, thiab tseem txhim kho qhov kub - ua thiab txias - ua cov khoom.
3.What yog sib npaug rau hastelloy b3?
Tsis muaj cov ntaub ntawv zoo ib yam li qub, tab sis qee cov npe menyuam yaus - raws li cov khoom sib xws, xws li qee cov yam ntxwv tshwj xeeb, thiab lawv yuav tsum tau xaiv raws li cov kev thov tshwj xeeb.
4.What yog qhov sib txawv ntawm hastelloy b3 thiab b2?
Tshuaj Muaj Tshuaj: Hastelloy B2 muaj qhov yooj yim ntawm npib tsib xee (NI), Molybdenum cov ntsiab lus ntawm txog 26% thiab cov hlau hlau ntawm 2% {}}}%. Hastelloy B3 tseem ceeb txo cov hlau thiab cov ntsiab lus carbon tsawg dua lossis sib npaug ntawm 1%), thiab ntxiv rau 1%. {%) Kom txhim kho oxidation tsis kam.
Corrosion Kuj: B2 Ua tau zoo hauv nruab nrab - concmor acid (20% {3}}%) thiab nws cov kev ua kom muaj qhov kub thiab txias) lossis ib puag ncig muaj oxidizing impurities. Thiab nws yog nquag nquag ua kom sov - cuam tshuam cheeb tsam corrosion tom qab vuam. B3 tau txhim kho kom zoo dua hauv cov kev sib tham no. Piv txwv li, nyob rau hauv ib tug npau 10% hydrochloric tus nqi ntawm B3 yog li 1\/3 ntawm tias B2, thiab nws muaj ntau cov xeb khov kho tsis kam rau hauv cov kua qaub sib xyaw uas muaj oxidizing ions.
Cov Khoom Siv Neeg Kho Tshuab: Cov khoom siv tshuab ntawm ob lub alloys zoo sib xws. Lub zog tensile nyob rau hauv chav tsev kub yog ob qho tib si tshaj 700mpa, thiab lub elongation yog li 40% {2}}%. Tab sis b3 tau me ntsis siab dua - lub zog kub thiab muaj peev xwm tswj tau zoo dua ruaj khov hauv qab 400 degree.
Kev ua tau zoo: Cov kub - ua haujlwm ntau ntawm B3 yog dav (900 degree {{} {yog nqaim (1000 degree {6}} degree). Thaum ua haujlwm txias, ob qho tib si B2 thiab B3 yuav tsum tau them sai sai rau B3 me me qis dua rau kev ua kom txias - cov khoom sib xyaw. Tsis tas li ntawd, lub tshuab luam ntawv ntawm b3 yog me ntsis zoo dua li B2, thiab lub cuab tam lub neej tuaj yeem txuas ntxiv los ntawm kwv yees li 15% {15}}%.
Daim Ntawv Thov Kev Pab Cuam: B2 yog tsim nyog rau kev txo ib puag ncig ntawm cov ntsuas kub qub lossis nruab nrab dua lossis muaj kev sib npaug nrog 80 degree), xws li qis dua - degree), xws li qis dua li 80 degree), xws li qhov qis dua - degree), xws li cov kua muag hydrochloric acid cia khoom thiab acetic acid cov khoom siv ntau lawm. B3 yog dav siv nyob rau hauv ib puag ncig corrosive ruaj khov, xws li evaporators ntawm siab -} kav dej qab zib acid (thiab leej faj - muaj cov khoom siv roj thiab roj ntau lawm.
