I-sodium bromideiyinhlanganisela engaphili enefomula yamakhemikhali i-NaBr. Ikhona njengamakristalu e-cubic angenambala noma i-white granular powder, ayinaphunga elinokunambitheka okunosawoti nokubabayo kancane. I-sodium bromide ivame ukumunca umswakama emoyeni bese yakha ama-clumps, yize ingancibiliki. Incibilika kakhulu emanzini, ikhipha isixazululo esingathathi hlangothi, futhi incibilika kancane otshwaleni. Uma isabela ku-sulfuric acid encibilikisiwe, ikhiqiza i-hydrogen bromide. Ngaphansi kwezimo ze-acidic, i-sodium bromide ingancibilikiswa ukuze ikhiphe i-bromine eyisisekelo.
Kubuchwepheshe bezithombe, i-sodium bromide isebenza ngokuyinhloko imisebenzi emibili: njenge-ejenti ezwela ukukhanya kanye ne-ejenti ekhulayo.
Njenge-ejenti ezwela ukukhanya,i-sodium bromideivumela ukuqoshwa kwesithombe ngokusebenzisa ukusabela okubangelwa ukukhanya. Uma ivezwa ekukhanyeni okukhanyayo noma okubonakalayo, i-sodium bromide ibhekana nokusabela kwe-photochemical ukuze yakhe izithombe ezinezimpawu ezithile zethoni. Idlala indima ebalulekile kokubili ekuthwebuleni izithombe zefilimu zendabuko kanye nasekuthathweni kwezithombe zedijithali, ikakhulukazi ekukhiqizweni kwamafilimu ezithombe amnyama namhlophe nombala.
Njenge-ejenti ekhulayo, i-sodium bromide yenza imisebenzi ebalulekile ezinqubweni zokuthuthukiswa kwefilimu. Ngesikhathi sokuthuthukiswa, isabela nama-ion esiliva kuma-emulsions azwela ukukhanya ukuze yakhe i-silver bromide, ngaleyo ndlela iveze izithombe ezifihliwe ezithombeni ezibonakalayo. Lolu hlelo lokusebenza luvumela abathwebuli bezithombe ukuthi bathole ukucaca okuthuthukisiwe kanye nemininingwane emincane ezithombeni zabo. Ngaphezu kwalokho, ukwanda okulawulwayo kokuhlushwa kwama-ion e-bromide kusiza ukuvimbela ukuncibilika kwama-halide esiliva angavezwanga, ngaleyo ndlela kulawula izinga lokuthuthukiswa futhi kuvimbele izinguquko zamakhemikhali ezingadingeki.
Ngamafuphi, izindima ezimbili ze-sodium bromide ekuzweleni izithombe nasekuthuthukisweni kwezithombe zibe yisisekelo sobuchwepheshe bezithombe, okwenza kube lula ukuthwebula nokwethula izithombe ezibonakalayo.
Sihlinzekai-sodium bromide(isithombe sebanga) ngentengo efanelekile, isiqinisekiso sekhwalithi. Sicela uvakashele iwebhusayithi yethu www.toptionchem.com ukuthola ulwazi olwengeziwe. Uma unesidingo, sicela ungangabazi ukuxhumana nathi.
