Katundu ndi Kugwiritsa Ntchito Sodium Cyanide, Mankhwala Oopsa Kwambiri

Sodium cyanide (NaCN) ndi mankhwala oopsa kwambiri omwe amadziwika chifukwa chakupha komanso kusiyanitsa Chemical katundu. Nkhaniyi delves mu thupi ndi mankhwala makhalidwe a Sodium cyanide ndikuwunika ntchito zake zosiyanasiyana, ndikuwunikiranso kufunikira kwa chitetezo ndi kuwongolera malamulo.

Zomangamanga ndi Zachilengedwe

Sodium cyanide ndi yoyera, yolimba ngati kristalo yomwe imafanana ndi mchere wamchere m'mawonekedwe. Amasungunuka kwambiri m'madzi, ndipo amatha kupanga njira yomveka bwino komanso yopanda mtundu. Kusungunuka kumeneku kumathandizira kufalikira kwake mwachangu m'malo amadzi, komwe kumawonjezera kawopsedwe ake. Ndi malo osungunuka a 563.7 ° C ndi malo otentha a 1496 ° C, Sodium Cyanide zimasonyeza kukhazikika kwa kutentha kwapamwamba pansi pazikhalidwe zabwinobwino.

Mwamwayi, sodium cyanide imathamanga kwambiri. Imalekanitsa m'madzi kuti itulutse ma cyanide ions (CN-), omwe amachititsa kuti pakhale poizoni. Ikakhudzana ndi zidulo, sodium cyanide imachita mwamphamvu kupanga hydrogen cyanide (HCN), mpweya wotentha kwambiri komanso wapoizoni kwambiri. Izi zimabweretsa chiopsezo chachikulu, chifukwa ngakhale kuchuluka kwa asidi kumatha kuyambitsa kutulutsa kwakufa kwa hydrogen cyanide. Kuphatikiza apo, sodium cyanide imatha kuchitapo kanthu ndi zitsulo zosiyanasiyana kupanga zitsulo zolimba za cyanide, zomwe zimagwiritsidwa ntchito m'mafakitale angapo.

Mapulogalamu a Industrial

Ngakhale kuti ili ndi poizoni wambiri, sodium cyanide imagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana. Chimodzi mwazinthu zofunikira kwambiri za sodium cyanide ndi m'makampani amigodi, makamaka pakuchotsa golide ndi siliva. Njirayi, yomwe imadziwika kuti cyanidation, imaphatikizapo kusungunula zitsulo zamtengo wapatali kuchokera ku miyala yawo pogwiritsa ntchito njira yothetsera sodium cyanide. Ma cyanide ions amapanga zinthu zosungunuka ndi golide ndi siliva, zomwe zimapangitsa kuti azipatukana ndi matrix ore. Njirayi ndi yothandiza kwambiri komanso yogwiritsidwa ntchito kwambiri chifukwa chotha kuchotsa zitsulo kuchokera kuzitsulo zotsika kwambiri, zomwe zimapangitsa kuti pakhale ndalama zothandizira ntchito zazikulu zamigodi.

Sodium cyanide imapezanso ntchito mumakampani opanga ma electroplating. Amagwiritsidwa ntchito ngati chothandizira kuti akhazikitse ayoni azitsulo m'malo osambira a electroplating. Popanga ma complex olimba okhala ndi ayoni achitsulo, sodium cyanide imawonetsetsa kuti chitsulocho chikhale chokhazikika komanso chokhazikika pagawo lapansi, zomwe zimapangitsa kuti pakhale zinthu zapamwamba kwambiri zama electroplated. Izi ndizofunikira makamaka popanga zodzikongoletsera, zida zamagalimoto, ndi zida zamagetsi, pomwe chitsulo chosalala komanso chokhazikika chimafunikira.

M'makampani opanga mankhwala, sodium cyanide imagwira ntchito ngati chinthu chofunikira kwambiri popanga zinthu zosiyanasiyana zachilengedwe komanso zachilengedwe. Amagwiritsidwa ntchito popanga mankhwala, mankhwala ophera tizilombo, utoto, ndi mankhwala ena. Mwachitsanzo, sodium cyanide imagwiritsidwa ntchito popanga ma cyanohydrins, omwe ndi ofunikira kwambiri popanga mankhwala ndi agrochemicals. Komabe, chifukwa cha kawopsedwe kake, malamulo okhwima otetezedwa ndi njira zogwirira ntchito ziyenera kutsatiridwa mukamagwiritsa ntchito sodium cyanide popanga mankhwala.

Chitetezo ndi Kuwongolera Malamulo

Chifukwa cha kawopsedwe kake, sodium cyanide imayenera kulamulidwa mwamphamvu m'maiko ambiri. Kagwiridwe, kasungidwe, ndi kayendetsedwe ka sodium cyanide amayendetsedwa mwamphamvu kuti asawonekere mwangozi komanso kuipitsidwa ndi chilengedwe. Ogwira ntchito ya sodium cyanide akuyenera kuphunzitsidwa mwapadera ndi kuvala zida zodzitetezera (PPE), kuphatikiza magolovesi, magalasi, ndi zopumira. Pakatayika kapena kutulutsidwa, njira zoyankhira mwachangu komanso zoyenera ziyenera kuchitidwa kuti muchepetse chiopsezo chowonekera komanso kuwonongeka kwa chilengedwe.

Pomaliza, sodium cyanide ndi chinthu chapoizoni kwambiri koma chofunikira kwambiri m'mafakitale chomwe chili ndi mawonekedwe apadera komanso makemikolo. Ntchito zake mumigodi, electroplating, ndi kaphatikizidwe ka mankhwala zimawonetsa kufunikira kwake m'mafakitale osiyanasiyana. Komabe, kawopsedwe wowopsa wa sodium cyanide amafunikira miyeso yolimba yachitetezo ndikuwongolera kuti ateteze thanzi la anthu komanso chilengedwe. Pamene mafakitale akupitirizabe kudalira sodium cyanide, kufufuza kosalekeza ndi ntchito zachitukuko zikuyang'ana pa kupeza njira zotetezeka komanso kukonza ndondomeko za chitetezo kuti achepetse kuopsa kwa ntchito yake.
