Dab tsi 's Silver Point rau hloov thiab lub qhov rooj?

Silver point yog qhov chaw sib tiv tauj ntawm cov khoom seem hauv cov txheej txheem ntawm kev hloov. Ua ntej, nyob ntawm seb qhov loj ntawm kev sib cuag, qhov loj dua qhov zoo. Secondly, nyob ntawm seb cov khoom, muaj peb hom khoom: silver-nickel alloy, silver-cadmium alloy thiab dawb huv nyiaj.

Silver-nickel alloy yog ib qho khoom siv zoo rau tam sim no. Nws muaj hluav taws xob ua kom zoo, nyuaj thiab tsis yooj yim rau oxidize thiab xeb.

Silver-cadmium alloy hu kuj zoo nyob hauv lwm yam, tab sis cadmium belongs rau heavy co. Nyob rau hauv ib tes, cadmium yog teeb meem rau tib neeg lub cev, ntawm qhov kev tes, nyiaj fusion tsis zoo tagnrho. Cov tshuaj me me me me yuav ua rau ntawm qhov chaw ntu, thiab yuav tau rub tawm thaum hluav taws xob.

Pure silver yog tsis haum rau cov neeg. Nws muaj hluav taws xob zoo, tab sis nws yog mos thiab yooj yim rau oxidize (xws li nyiaj hniav nyiaj hniav nyiaj yuav tig dub tom qab ntev). Kev ntxhib los mos mos, muaj kev sib txuas ntau ntawm tus tes hloov qhov yuav hloov tau; oxidation xeb, cov conductivity yuav muaj ntau zuj zus, xeb yog yooj yim rau cua sov, nws yog ib qho yooj yim mus hlawv cov neeg.
