Vim muaj cov khoom zoo nuclear thiab corrosion kuj ntawm zirconium,polished zirconium pas nrigfeem ntau yog siv rau hauv cov khoom siv hluav taws xob nuclear thiab cov qauv sab hauv ntawm cov dej-txias reactors thiab yog cov ntaub ntawv tseem ceeb ntawm nuclear. Zirconium rods feem ntau yog siv los tsim cov khoom siv tshuaj. Lub zirconium pas nrig yog cov nyiaj dawb-dawb electroplating hlau, uas yog ib qho yooj yim los tsim ib tug oxide zaj duab xis rau saum npoo, uas yog ci thiab zoo ib yam li cov hlau thiab corrosive. Thaum qhov kub thiab txias, nws tuaj yeem hnov mob nrog cov ntsiab lus tsis yog xim hlau thiab ntau lub ntsiab lus hlau los tsim cov khoom sib xyaw ua ke. Cov pas nrig zirconium muaj cov yas zoo thiab yooj yim rau kev ua tiav rau hauv ib lub phaj, uas tuaj yeem rub mus rau hauv ib lub zirconium hlau, thiab tseem tuaj yeem ua rau hauv cov khoom siv, thiab lwm yam. Thaum tungsten yog rhuab, nws tuaj yeem nqus tau cov pa oxygen ntau. , hydrogen, nitrogen, thiab lwm yam gases, thiab yog siv los ua hydrogen cia khoom.

Zirconium, ib qho khoom tseem ceeb, feem ntau muaj nyob rau hauv qhov xwm txheej ntawm cov zaub mov. Cov ntsiab lus tsis raug ntawm tungsten nyob rau hauv lub ntiaj teb crust qib 20th, ntau dua li cov hlau xws li tooj liab, lead, npib tsib xee, thiab zinc, tab sis nws yog hu ua cov hlau tsis tshua muaj vim yog kev sib piv ntawm cov txheej txheem tsim khoom. Complex thiab tsis yooj yim rau rho tawm hauv kev lag luam. Tsis tas li ntawd, ntawm ntau tshaj 40 hom plutonium deposits pom, tsuas muaj li ntawm 10 hom kev lag luam mining nqi, thiab tsuas yog ob hom plutonium thiab plaub-sided pyramids yog siv rau kev tsim khoom. Zirconium muaj ntau yam kev siv. Zirconium suav txog li 3 feem pua rau 4 feem pua thiab feem ntau yog siv hauv ceramics thiab cov ntaub ntawv refractory nyob rau hauv daim ntawv ntawm zirconium silicate thiab zirconium oxide. Ib feem ntawm daim ntawv thov no suav nrog ntau dua 90 feem pua ntawm zirconium noj. Tsis tas li ntawd, zirconium muaj cov khoom siv hluav taws xob zoo heev, yog li lub thermal neutron absorption cross-section me me, tsuas yog 0.1810-28. Ib qho tseem ceeb ntawm kev siv zirconium thiab nws cov alloys yog cov khoom siv roj thiab lwm yam khoom siv rau cov reactors nuclear. Yog li ntawd, kev tshawb fawb thiab kev loj hlob ntawm zirconium thiab zirconium alloys yog ze ze rau txoj kev loj hlob ntawm nuclear fais fab kev lag luam. Lawv tau pib siv rau cov nkoj siv hluav taws xob nuclear, thiab tom qab ntawd lawv tau nquag tsim rau cov chaw tsim hluav taws xob nuclear.
Zirconium pas nrig yog cov hlau ua haujlwm nrog kev sib raug zoo rau cov pa oxygen, yog li kev tiv thaiv oxide zaj duab xis hauv huab cua ntawm chav tsev kub yuav tsim cov yeeb yaj kiab oxide tiv thaiv, uas ua rau tungsten thiab nws cov alloys muaj kev tiv thaiv corrosion zoo heev. Tungsten muaj zog corrosion kuj muaj zog tsis kam mus rau ntau hom tin-hom xov xwm, thiab muaj cov khoom siv hluav taws xob thiab hluav taws xob hloov pauv, nrog rau cov txiaj ntsig zoo, ua rau nws yog cov khoom siv zoo heev hauv kev lag luam petrochemical niaj hnub no.
Cov ntshiab zirconium rods tsim los ntawm Baoji Yusheng tuam txhab yog dav siv nyob rau hauv lub siab hlab ntsha, tshav kub exchangers, kav, tso tsheb hlau luam, shafts, mixers thiab lwm yam mechanical khoom, li qub, twj tso kua mis, sprayers, tais, riam phom, ntauwd linings, thiab lwm yam txheej txheem los tiv thaiv corrosion. khoom siv. Raws li kev txheeb cais, nws tau ua tiav nyob rau hauv daim ntawv ntawm zirconium (los yog daim txhuam cev zirconium) thiab tom qab ntawd ua tiav rau hauv zirconium alloy, uas yog tsim rau cov khoom siv hluav taws xob nuclear lossis kev lag luam. Nyob rau hauv cov nqe lus ntawm kev ua theem nyuaj thiab technology, cov hlau kev lag luam saw yog nyob rau hauv ib tug kuj zoo.
