Cov khoom siv
Cadmium yog siv nyob rau hauv electroplating, nyob rau hauv nickelcadmiumstorage roj teeb, raws li ib tug txheej rau lwm cov hlau, nyob rau hauv bearing thiab low-meltingalloys, thiab raws li tswj rods nyob rau hauv nuclear reactors.Cadmium tebchaw muaj ntau yam kev siv, xws li dyeing thiab printing textiles, raws li TV phosphors, thiab pigments. nyob rau hauv semiconductors thiab solarcells.
Cadmium alloyed nrog nyiaj ua ib hom solder nrog lub melting point tsawg. Nws yog siv los koom nrog cov hluav taws xob junctions thiab lwm yam khoom tshwj xeeb hlau. Yuav tsum ceev faj vim nws yog ib yam tshuaj lom. (Faj seeb: Qhov no tsis yog tib yam li cov khoom siv uas siv los koom nrog cov hlau, uas muaj kev nyab xeeb.) Lwm cov cadmium alloys yog siv los tsim cov bearings ntev thiab ua cov txheej nyias rau cov hlau los tiv thaiv corrosion.
Cadmium yog ib tug neutron absorber, ua rau nws siv tau raws li kev tswj rods nyob rau hauv nuclear reactors. Therods raug tsa los qhib lub reactor thiab tom qab ntawd txo qis rau hauv lub reactor kom nqus cov neutronsthat nres lub fission cov tshuaj tiv thaiv.Cadmium, nrog rau cov npib tsib xee, tsim cov nickel-cadmium alloy siv los tsim "nicadbatteries" uas zoo li zoo li qub me me qhuav-cell. roj teeb.
cadmium yog cov tshuaj lom heev. Cadmium feem ntau tuaj yeem pom hauv cov roj teeb.cadmium tsim cov oxide sib thooj thaum cua sov hauv qab oxygen. cadmium ua raws li cov qauv dav dav MX2 thiab yog insoluble (X = F) hauv dej los yog qhia cov dej solubility tsawg.
Ntim Thiab Cia
Ntim:
Ntim hauv1kg ib lub hnab rau kev kuaj,25kg lossis 50kg rau ib lub nruas,los yog raws li koj xav tau.
Lus Cim: Cov tshuaj muaj pes tsawg leeg thiab qhov loj tuaj yeem ua kom zoo los ntawm cov neeg siv khoom xav tau
Cov xwm txheej rau kev ruaj ntseg cia, suav nrog txhua qhov tsis sib xws
Khaws lub thawv kaw kom nruj rau hauv qhov chaw qhuav, txias thiab zoo-ventilated.
Kev Tiv Thaiv Kev Nyab Xeeb
Kev ceev faj rau kev nyab xeeb
Tsis muaj kev sib cuag nrog oxidizing agents. Kaw qhov system, plua plav tawg-pov thawj cov khoom siv hluav taws xob thiab teeb pom kev zoo. Tiv thaiv kom tsis txhob muaj plua plav. Tuav nyob rau hauv qhov chaw zoo ventilated. Hnav khaub ncaws tiv thaiv kom haum. Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag. Tsis txhob tsim cov hmoov av thiab aerosols. Siv cov cuab yeej uas tsis muaj teeb meem. Tiv thaiv hluav taws los ntawm electrostatic tawm chav.
