Zirconium muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv thaiv corrosion los ntawm feem ntau cov organic acids, inorganic acids, muaj zog alkalis thiab qee cov ntsev molten. Yog li ntawd, qee qhov tseem ceeb hauv qhov chaw corrosive tuaj yeem siv zirconium los txhim kho lawv lub neej kev pab. Corrosion-resistant zirconium alloys yog Zr702, Zr704, Zr705 thiab Zr706 alloys. Cov muaj pes tsawg leeg ntawm Zr702 alloy yog ze rau cov ntshiab zirconium, feem ntau ntxiv me me ntawm O, H thiab N ntsiab lus. Nws muaj siab corrosion kuj tab sis tsis tshua muaj neeg kho tshuab zog. Zr702 alloy yog high-purity zirconium alloy nrog zoo corrosion kuj thiab txhua yam khoom.
1. Cov ntsiab lus
Zr702 alloy yog tsim los ntawm zirconium (Zr) thiab me me ntawm hlau (Fe), chromium (Cr), countersun (Hf) thiab lwm yam. Nws cov tshuaj muaj pes tsawg leeg yog raws li nram no:
Zirconium (Zr): Cov ntsiab lus feem ntau yog nruab nrab ntawm 99.2% thiab 99.7%, uas yog cov khoom tseem ceeb ntawm cov hlau, muab cov alloy zoo heev corrosion kuj thiab tshuaj stability.
Hlau (Fe): Cov ntsiab lus yog tswj hauv qab no 0.02%. Ntxiv hlau tuaj yeem txhim kho lub zog thiab hardness ntawm alloy.
Chromium (Cr): Cov ntsiab lus yog tswj hauv qab no 0.05%. Ntxiv chromium alloy tuaj yeem ua rau oxidation tsis kam, tshwj xeeb tshaj yog corrosion kuj rau oxidizing media.
Countersunk (Hf): Cov ntsiab lus feem ntau yog tsawg dua 4%. Qhov sib ntxiv ntawm countersunk tuaj yeem txhim kho corrosion kuj thiab kub tsis kam ntawm alloy.
2. Cov yam ntxwv zoo heev
Qhov zoo ntawm Zr702 alloy yog qhov tseem ceeb ntawm nws cov corrosion kuj, tshuaj stability thiab txhua yam khoom. Nws muaj kev tiv thaiv corrosion zoo thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv ntau yam corrosive media. Nws yog resistant rau muaj zog acids, muaj zog alkalis, oxidation thiab lwm yam corrosion. Nyob rau tib lub sij hawm, lub siab-purity zirconium tivthaiv muab cov alloy zoo heev tshuaj stability, thiaj li hais tias nws muaj peev xwm tswj stability thiab kev ntseeg tau thaum lub sij hawm kev kho mob tshuaj. Tsis tas li ntawd, Zr702 alloy kuj muaj cov khoom siv zoo, nrog rau lub zog siab, zoo ductility thiab cuam tshuam lub zog, uas ua rau nws ua tau raws li qhov xav tau ntawm engineering ntawm ntau qhov chaw.
3. Daim ntawv thov teb
Ua ntej tshaj plaws, nws yog dav siv nyob rau hauv kev lag luam tshuaj, tshwj xeeb tshaj yog nyob rau hauv kev tsim khoom nyob rau hauv deteriorating xov xwm. Nws tuaj yeem tswj tau ntau yam muaj zog acids, alkalis thiab tiv thaiv corrosion thaum tsim khoom xws li reactors, tso tsheb hlau luam, kub exchangers, kav dej thiab li qub.
Qhov thib ob, Zr702 alloy kuj yog ib qho khoom siv zoo tshaj plaws hauv kev lag luam nuclear. Vim nws cov hluav taws xob zoo thiab kev tiv thaiv corrosion, nws tuaj yeem siv los tsim cov khoom siv hluav taws xob nuclear, cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv hluav taws xob pov tseg.
Tsis tas li ntawd, hauv kev tsim khoom siv kho mob, Zr702 alloy kuj muaj ntau yam kev siv. Nws muaj biocompatibility zoo thiab corrosion kuj thiab tuaj yeem siv los tsim cov pob qij txha, kev cog hniav thiab lwm yam khoom siv kho mob corrosion-resistant.
Thaum kawg, hauv kev lag luam aerospace, lub zog siab thiab corrosion kuj ntawm Zr702 alloy ua rau nws yog ib qho khoom tseem ceeb. Nws tuaj yeem siv los tsim cov tshuab dav hlau qhov chaw, turbines thiab cov qauv siv dav hlau, thiab lwm yam.
Peb lub tuam txhab tuaj yeem muab cov khoom lag luam siab purity zirconium xws liZirconium Zr702 Disc, Zr702 Hlau Qwsthiab Zirconium TIG Hlau, thiab lawv txhua tus tau lees paub los ntawm ISO cov chaw soj ntsuam zoo. Tau kawg, peb tuaj yeem muab lwm yam khoom siv hlau tsis muaj hlau. Yog tias koj txaus siab rau kev txiav txim, thov xa email rau peb.
