Cadmium Hlau Description
Cadmium yog nyob rau hauv cov xim nyiaj-dawb thiab muaj peev xwm ntawm kev siv lub siab polish. Nws yuav luag li mos li tin thiab nws tawm suab nrov thaum khoov ib yam li tin. Cadmium tuaj yeem dov tawm mus rau hauv nplooj ntawv. Cadmium melts thiab boils ntawm qhov kub tsis tshua muaj. Cadmium vapor yog sib sib zog nqus daj thiab monatomic. Cadmium hlau yog ruaj khov hauv huab cua qhuav; ua coated nrog oxide nyob rau hauv cov huab cua noo; kub hnyiab ntawm cua sov kom liab; thiab yog yooj yim soluble nyob rau hauv mineral acids. Kev ua xua tshwm sim los ntawm kev nqus cov plua plav lossis vapor ntawm cadmium.
Feem ntau cov cadmium tsim tau siv los ua electroplating rau steel, hlau, tooj liab, tooj dag, thiab lwm yam alloys los tiv thaiv lawv ntawm corrosion. Cadmium plating tshwj xeeb tshaj yog tiv thaiv kev tawm tsam los ntawm alkali. Cadmium yog lub cev zoo ib yam li zinc tab sis yog softer thiab denser. Cov plated cadmium muaj cov nplej me me dua li cov txheej txheej electro zinc, thiab cov deposits zoo li du thiab sib xws. Yog li ntawd, kev tiv thaiv zoo yog muab los ntawm nyias cadmium txheej, thiab yog li, txawm tias nws cov nqi siab, nws nquag siv rau kev tiv thaiv ntawm precision qhov chaw. Cadmium tsis kam rau cov huab cua hauv hiav txwv kuj zoo dua li zinc.
Daim ntawv thov tseem ceeb ntawm cadmium yog siv los ua cov anode nrog npib tsib xee lossis nyiaj oxide li cathode thiab caustic potash electrolyte nyob rau hauv rechargeable hluav taws xob cia roj teeb rau siv nyob rau hauv dav hlau qhov twg nws txo qhov hnyav, lub neej ntev, thiab ruaj khov thaum cia nyob rau hauv qhov chaw tso tawm. yog ntshaw.
Cadmium ua ke nrog ntau cov hlau hnyav los ua cov hlau. Qhov tseem ceeb tshaj plaws yog bearing alloys thiab low-melting alloys rau brazing. Qhov sib ntxiv ntawm me me ntawm cadmium ntxiv dag zog rau cov hlau hnyav. 1 feem pua ntxiv rau tooj liab nce nws lub zog thiab hardness nrog tsuas yog txo me me hauv hluav taws xob conductivity. Cadmium cov ntaub ntawv solders nrog zoo shear zog thaum alloyed nrog zinc. Raws li nws zoo absorbs thermal neutrons, nws yog siv nyob rau hauv kev tswj rods rau ib co nuclear reactors.
