Dab tsi yog qhov zoo ntawm corrosion-resistant alloy khoom
Corrosion-resistant alloys feem ntau tsis tuaj yeem siv rau hauv qhov chaw corrosive nrog lub zog txo qis lossis kev ua haujlwm siab sealing (anoxic ib puag ncig), thiab kev ua haujlwm ntawm cov khoom tau hloov kho tas li, thiab lawv tau siv dav, thiab muaj ntau lub tuam txhab tsim khoom, yuav ua li cas. xaiv Cov chaw tsim khoom uas haum rau koj yog kev tshawb fawb.Ntawm qhov tod tes, kev paub yuav tsum tau txiav txim siab txog tus nqi, thiab lwm yam yuav tsum tau txiav txim siab zoo, xws li seb cov chaw tsim khoom puas raug tswj thiab seb qhov kev pab cuam tom qab muag puas tau lav.
Corrosion Resistant Alloy
Dab tsi yog hom ntawm corrosion resistant alloys?
1. Corrosion ntawm stainless hlau
Feem ntau yog hais txog qhov zoo tib yam 300 series stainless hlau 304, 316L, 317L, thiab lwm yam uas tiv taus atmospheric lossis seawater corrosion;austenitic stainless hlau 904L, 254SMO nrog muaj zog corrosion kuj;duplex steel 2205, 2507, thiab lwm yam.;corrosion-resistant alloys uas muaj CU 20 alloy, thiab lwm yam.
2. Base corrosion-resistant alloy
Feem ntau Hastelloy alloy thiab NI-CU alloy, thiab lwm yam. Txij li thaum cov hlau NI nws tus kheej muaj lub ntsej muag-centered cubic qauv, nws crystallographic stability enables nws kom haum ntau alloying ntsiab dua FE, xws li CR, MO, thiab lwm yam., thiaj li mus cuag tau tsis kam Lub peev xwm ntawm ntau qhov chaw;Nyob rau tib lub sijhawm, npib tsib xee nws tus kheej muaj peev xwm tiv thaiv corrosion, tshwj xeeb tshaj yog muaj peev xwm tiv thaiv kev ntxhov siab los ntawm chloride ions.Nyob rau hauv qhov muaj zog reductive corrosion ib puag ncig, complex sib xyaw acid ib puag ncig, thiab cov kev daws teeb meem uas muaj halogen ions, npib tsib xee-raws li corrosion-resistant alloys sawv cev los ntawm Hastelloy muaj qhov zoo ntawm cov hlau tsis muaj hlau.
3.Hastelloy belongs rau npib tsib xee-molybdenum-chromium-hlau-tungsten npib tsib xee-raws li alloy.Nws yog ib qho ntawm feem ntau corrosion-resistant niaj hnub hlau cov ntaub ntawv.Nws yog tsuas yog resistant rau ntub chlorine, ntau yam oxidizing chlorides, chloride ntsev daws, sulfuric acid thiab oxidizing ntsev, thiab muaj zoo corrosion kuj nyob rau hauv qis kub thiab nruab nrab kub hydrochloric acid.Yog li ntawd, nyob rau hauv peb lub xyoos dhau los, nws tau dav siv nyob rau hauv hnyav corrosive ib puag ncig, xws li tshuaj lom neeg kev lag luam, petrochemical kev lag luam, flue roj desulfurization, pulp thiab ntawv, ib puag ncig tiv thaiv thiab lwm yam industrial teb.Cov ntaub ntawv corrosion ntau yam ntawm Hastelloy alloys yog qhov raug, tab sis lawv tsis tuaj yeem siv raws li cov lus qhia tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv qhov chaw tsis paub, thiab cov ntaub ntawv yuav tsum raug xaiv tom qab kuaj.Tsis muaj Cr hauv Hastelloy txaus los tiv thaiv corrosion hauv qhov chaw oxidizing, xws li kub concentrated nitric acid.Kev tsim cov hlau no feem ntau yog rau cov txheej txheem tshuaj ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv lub xub ntiag ntawm cov kua qaub sib xyaw, xws li cov yeeb nkab tawm ntawm flue gas desulfurization system.
