1. Khoom piav qhia
Tantalum muaj kev ruaj ntseg ntawm chav tsev kub, me me linear expansion coefficient, zoo ductility, siab thermal conductivity, thiab zoo kub-kub lub zog thiab processability. Kev tiv thaiv corrosion ntawm tantalum yog zoo dua li ntawm titanium, zirconium, thiab niobium. Ntxiv nrog rau fuming sulfuric acid, hydrofluoric acid, thiab lwm yam xov xwm, corrosion kuj ntawm tantalum nyob rau hauv feem ntau industrial acids yog zoo heev. Tantalum tsis hnov tsw rau thais thiab tsis nquag rau hauv zos corrosion xws li corrosion qaug zog. Hom corrosion yog uniform corrosion. Yog li ntawd, tantalum yog tsuas yog siv nyob rau hauv petrochemical khoom nyob rau hauv daim ntawv ntawmtantalum composite steel phajthiab cov txheej txheem hauv ob sab phlu.
2. Khoom nta
Tom qab ntau qhov kev ntsuam xyuas, daim duab schematic ntawm kev sib raug zoo ntawm qhov sib txuas ntawm qhov kub thiab txias t thiab thickness h ntawm cov txheej txheem sib xyaw yog tsim, raws li qhia hauv daim duab 2. Fig. 2 Qhov kev sib raug zoo ntawm qhov kub thiab txias cladding tuaj yeem pom los ntawm cov daim duab: ① Thaum h Tsawg dua los yog sib npaug rau 2.0mm, lub interface steel melts, thiab cov khoom hlau diffuses rau hauv cov vuam, ua rau tawg. ② Thaum h ＞ 2. Txhawm rau tiv thaiv weld tawg thaum lub sij hawm vuam, peb txoj hauv qab no tau txais yuav:
① Ua kom lub thickness ntawm cladding. ② Txo qhov kub ntawm qhov interface. ③ Sib cais tantalum weld los ntawm steel puag. Txoj Kev 1 yuav nce tus nqi tsim khoom, thiab qhov ua tau yog dav dav. Txoj Kev 2 tuaj yeem ua kab ib txheej ntawm lwm cov hlau (xws li tooj liab) nrog kev kub ceev ceev ntawm qhov sib cuam tshuam, thiaj li hloov cov cua sov tsim thaum lub sij hawm vuam mus rau ib puag ncig. Vim qhov zoo thermal conductivity ntawm tooj liab, txoj kev ntawm padding tooj liab ntawm tantalum liner vuam taw tes yog ib zaug siv, tab sis txoj kev no yog heev cumbersome thiab undesirable. Txoj Kev 3 yog qhov ncaj thiab yooj yim, uas kuj tseem ceeb hauv daim ntawv.
3. Peb qhov zoo
Tam sim no, lub tuam txhab muaj tantalum composite steel phaj ua cov kab ntau lawm, nrog 20 senior engineers, 50 engineers, thiab 260 cov kws tshaj lij. Lub tuam txhab muaj kev ua haujlwm siab heev, muaj zog technical force, ruaj khov thiab zoo heev, khoom xa tuaj raws sijhawm, thiab lub koob npe nrov. Lub tuam txhab nyob rau ntawm No. 8, Ticheng Road, lub loj tshaj plaws nonferrous hlau puag nyob rau hauv Tuam Tshoj (Tuam Tshoj lub Titanium City), nyob ze rau Xibao Road, nrog heev yooj yim mus thauj.
4. FAQ
Cov ntsiab lus tseem ceeb ntawm cov txheej txheem tantalum
Kev nthuav dav thiab vuam
Hlau tantalum yog rhiab heev rau impurity immersion, yog li nws muaj kev xav tau siab rau qhov chaw vuam. Thaum rhuab saum 300 degree, hydrogen, oxygen, nitrogen thiab lwm yam gases nyob rau hauv cov huab cua yuav hnov mob hnyav nrog tantalum los ua nkig tebchaw; Nyob rau tib lub sijhawm, tantalum tseem yuav hnov mob nrog silicon, carbon, thiab boron los tsim cov nkig, txo nws cov plasticity thiab toughness. Yog li ntawd, kev tswj cov vuam ib puag ncig yuav tsum tau xav txog. Tsis tas li ntawd, vim qhov sib txawv ntawm thermal expansion coefficients ntawm tantalum tshav kub pauv cov hlab thiab cov ntawv raj tom qab qhov kub thiab txias, nws yog ib qho yooj yim kom txo tau lub zog rub tawm ntawm expansion pob qij txha. Thaum welding, nws yog ib qho tsim nyog yuav tau xav txog kev tiv thaiv lub inert gas channel nyob rau sab nraum qab ntawm welded sib koom [2]. Tantalum vuam qhov chaw yuav tsum huv si, tsis muaj plua plav thiab tsis muaj pa luam yeeb; Welders yuav tsum khaws lawv tej khaub ncaws, khau, thiab kaus mom kom huv si; Tantalum vuam qhov chaw yuav tsum tau muab faib ua qhov chaw ywj pheej kom tsis txhob muaj kev sib tsoo nrog kev cob qhia steel.
