Sodium Bromide (Chithunzi Cha Gulu)

Sodium bromideNdi chinthu chosapangidwa ndi zinthu zachilengedwe chomwe chili ndi formula ya mankhwala ya NaBr. Chimapezeka ngati makhiristo opanda mtundu kapena ufa woyera wa granular, wopanda fungo lokoma la mchere komanso lowawa pang'ono. Sodium bromide imakonda kuyamwa chinyezi kuchokera mumlengalenga ndikupanga machubu, ngakhale kuti sichisungunuka. Chimasungunuka kwambiri m'madzi, chimapereka yankho losalowerera, komanso chimasungunuka pang'ono mu mowa. Chikaphatikizidwa ndi sulfuric acid yochepetsedwa, chimapanga hydrogen bromide. Pakakhala acidity, sodium bromide imatha kusungunuka kuti itulutse elemental bromine.

Mu ukadaulo wa zithunzi, sodium bromide imagwira ntchito ziwiri makamaka: ngati chinthu chothandizira kuwala komanso ngati chinthu chothandizira kukula.

Monga wothandizira kuwala kwa dzuwa,sodium bromidezimathandiza kujambula zithunzi kudzera mu kuwala. Ikayang'aniridwa ndi ultraviolet kapena kuwala kooneka, sodium bromide imadutsa mu kuwala kwa photochemical kuti ipange zithunzi zokhala ndi mawonekedwe enieni a tonal. Imagwira ntchito yofunika kwambiri mu kujambula mafilimu achikhalidwe komanso kujambula kwa digito, makamaka popanga mafilimu akuda ndi oyera ndi amitundu yosiyanasiyana.

Monga chinthu chomwe chimapanga, sodium bromide imagwira ntchito yofunika kwambiri popanga filimu. Pakupanga, imagwira ntchito ndi ma ayoni asiliva mu emulsions omwe amalandira kuwala kuti apange siliva bromide, zomwe zimapangitsa kuti zithunzi zobisika ziwonekere. Pulogalamuyi imalola ojambula zithunzi kuti azitha kuwonekera bwino komanso tsatanetsatane wabwino pazithunzi zawo. Kuphatikiza apo, kuwonjezeka kwa ma ayoni a bromide kumathandiza kuletsa kusungunuka kwa ma halide asiliva osawonekera, potero kuwongolera kuchuluka kwa chitukuko ndikuletsa kusintha kwa mankhwala kosafunikira.

Mwachidule, ntchito ziwiri za sodium bromide pakupanga zithunzi ndi kupanga zithunzi zakhala zofunika kwambiri paukadaulo wazithunzi, zomwe zimathandiza kujambula ndi kuwonetsa zithunzi.

Timaperekasodium bromide(chithunzi cha giredi) ndi mtengo wabwino, chitsimikizo cha khalidwe. Chonde pitani patsamba lathu la www.toptionchem.com kuti mudziwe zambiri. Ngati muli ndi zofunikira, chonde musazengereze kulumikizana nafe.
