Name: Zirconium tube pas nrig
Zirconium alloy tubular material is made from zirconium metal and other metals. Due to the excellent nuclear properties and corrosion resistance of zirconium, zirconium alloy tube rods are often used for nuclear fuel assemblies and in-stack structures in water-cooled reactors and are an important nuclear material. Pure zirconium tubular rods are mainly used in the manufacture of chemical equipment, as they are expensive and not yet used in large quantities. The chemical composition of the commonly used zirconium pipe rods and their applications are shown in the table, among which zirconium-tin alloy pipe rods are used more often.
1) Zirconium muaj kev sib raug zoo nrog cov roj cua, nws pib hnov mob nrog cov pa, hydrogen thiab nitrogen nyob ib ncig ntawm 200, 300 thiab 400 ° C feem, thiab reacts sai heev ntawm qhov kub dua, yog li melting thiab casting, Kev kho cua sov yuav tsum tau nqa tawm hauv lub tshuab nqus tsev. Thaum ua cov txheej txheem cua sov tau nqa tawm hauv huab cua, kev tiv thaiv kom raug yuav tsum tau ua thiab lub sijhawm ua haujlwm ntawm qhov kub siab yuav tsum tau luv.
(2) Zirconium muaj qhov siab coefficient ntawm kev sib txhuam nrog cov pwm thiab yooj yim ua raws li cov pwm nto; qhov ua kom sov ntawm cov yas deformation yog qhov tseem ceeb, thiab cov txheej txheem lubrication zoo yuav tsum tau ua rau kev ua tiav.
(3) Kev ua haujlwm tshwj xeeb muaj qhov cuam tshuam ntau dua ntawm kev ua tau zoo ntawm cov khoom. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev tswj hwm cov khoom tiav ua ntej kev ua kom txias thiab txheej txheem kho cua sov kom tau raws li qhov xav tau ntawm kev siv.
(4) Qhov tseeb qhov tseeb thiab qhov zoo ntawm lub raj thiab kab ntawv yog siab heev. Yog li ntawd, cov txheej txheem txheej txheem yuav tsum muaj qhov ua tau zoo, tsim pwm thiab tsim khoom yuav tsum yog qib siab thiab tsim nyog
