Zirconium Alloy: Zr702 VS Zr705

Zr702 thiab Zr705

Lub ntsiabzirconium(Zr, 40) yog nyob rau hauv Pawg 4 thiab Lub Sijhawm 5 ntawm lub sijhawm teem sijhawm. Nws yog ib tug silver-grey hlau nrog impressive zog thiab corrosion kuj. Cov ntawv thov rau zirconium suav nrog cov khoom siv hluav taws xob, cov kav dej thiab cov fittings, lub twj tso kua mis thiab lub valve, lub tshuab hluav taws xob nuclear, lub hom phiaj sputtering, thiab lwm yam.

Muaj ob lub ntsiab ntawm corrosion-resistant zirconium alloys: Zr702 thiab Zr705, uas yog haum rau ntau yam tshuaj.

Zr702 yog zirconium alloy uas muaj 99.2% zirconium thiab 0.2% hydrogen. Kuj tseem hu ua Zircaloy-2, nws tau dav siv hauv cov ntawv siv hluav taws xob ua cov khoom siv rau cov pas nrig roj. Zr702 muaj kev tiv thaiv corrosion zoo heev thiab tsis tshua muaj neutron absorption, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau nuclear reactors.

Zr705 yog tsim los ntawm 95.5% zirconium, 2.0% niobium, 1.5% tin thiab 0.15% oxygen. Kuj tseem hu ua Zircloy-4, nws yog feem ntau siv hauv kev lag luam tshuaj lom neeg, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov ntaub ntawv raug kub thiab corrosive ib puag ncig.
