Iziqukathi Eziphephile Zokugcina I-Sodium Cyanide

Sodium i-cyanide iyinhlanganisela yamakhemikhali anobuthi kakhulu futhi eyingozi esetshenziswa kakhulu ezinqubweni ezehlukene zezimboni, njengokukhipha igolide nesiliva, i-electroplating, kanye nokuhlanganiswa kwamakhemikhali. Ngenxa yobuthi bayo obedlulele namandla ezingozi zemvelo nokuphepha, ukugcinwa okufanele kubaluleke kakhulu. Ukukhetha ilungelo Iziqukathi zokugcina kuyisici esibalulekile sokuqinisekisa ukuphathwa ngokuphephile kanye nokuvinjwa I-sodium cyanide. Lesi sihloko sihlola izinhlobo zezinto ezingasetshenziswa ngokuphepha ukuze zigcinwe I-Sodium Cyanide.

Ukuqonda Izakhiwo Ze-Sodium Cyanide

I-sodium cyanide (NaCN) iyisiqinile esimhlophe, esincibilika emanzini noma impushana ene-alimondi ebabayo - njengephunga. Isebenza kakhulu futhi ingadala ubungozi obubalulekile. Lapho ithintana namanzi, ama-asidi, noma izinsimbi ezithile, ingakhipha igesi ye-hydrogen cyanide, enobuthi obudlulele futhi engabulala ngisho nasezintweni ezincane. Ukwengeza, iyi-ejenti yokunciphisa enamandla futhi ingasabela ngobudlova ngama-oxidizing agents. Lezi zakhiwo zidinga ukuthi iziqukathi zokugcina zikhethwe ngokucophelela ukuze kuvinjelwe noma yikuphi ukusabela okungafuneki futhi kuqinisekiswe ubuqotho bezinto ezigciniwe. i-sodium cyanide.

Izidingo zokulawula ze-Sodium Cyanide Storage

Ngaphambi kokuhlolisisa izinto ezifanele zeziqukathi, kubalulekile ukwazi ngohlaka lokulawula olulawula ukugcinwa kwe-sodium cyanide. Emazweni amaningi, kunemithetho eqinile ebekiwe yokulawula ukuphathwa, ukugcinwa, kanye nokuthuthwa kwale nto eyingozi. Le mithethonqubo ivamise ukucacisa izidingo ezimayelana nokwakheka kweziqukathi, ukulebula, nokuhambisana namakhemikhali. Isibonelo, iziqukathi kufanele zilebulwe ngokucacile njengeziqukethe i-sodium cyanide, kanye nezixwayiso zengozi ezifanele. Ukuthobela le mithetho akusona nje isibopho esingokomthetho kodwa futhi kubalulekile ekugcineni ukuphepha emsebenzini nokuvikela imvelo.

Izinto Ezifanelekile Zesitsha

Insimbi engagqwali

Insimbi engagqwali iyisinqumo esidumile sokugcina i-sodium cyanide, ikakhulukazi kuzilungiselelo zezimboni. Ibanga 304 kanye ne-316 izinsimbi ezingenasici zivame ukusetshenziswa. Insimbi engagqwali inikeza ukumelana nokugqwala okuhle kakhulu, okubalulekile njengoba izixazululo ze-sodium cyanide zingagqwala, ikakhulukazi uma kukhona umswakama. Okuqukethwe kwe-chromium kunsimbi engagqwali kwakha isendlalelo se-oxide ye-passive ngaphezulu, okuvimbela insimbi ukuthi ingasabeli nge-cyanide. Nokho, kubalulekile ukuqaphela ukuthi insimbi engagqwali ingase ingafaneleki ukugcina i-sodium cyanide kuzo zonke izimo. Ezimweni ezine-acidic kakhulu noma lapho uthintana nokungcola okuthile, ukumelana nokugqwala kwensimbi engagqwali kungaba sengozini. Ukuhlolwa njalo kweziqukathi ezingenasici - zensimbi zezimpawu zokugqwala kuyadingeka ukuze kuqinisekiswe ubuqotho bazo obuqhubekayo.

I-High - Density Polyethylene (HDPE)

Iziqukathi ze-HDPE nazo zisetshenziselwa kakhulu ukugcina i-sodium cyanide. I-HDPE i-polymer ye-thermoplastic enokumelana okuhle kwamakhemikhali, okuhlanganisa ukumelana namakhemikhali amaningi njenge-sodium cyanide. Ilula, kodwa inamandla futhi ihlala isikhathi eside. Iziqukathi ze-HDPE azisebenzi ne-sodium cyanide ngaphansi kwezimo ezijwayelekile zokugcinwa, okuzenza zibe inketho ephephile. Abuye angabizi kakhulu uma kuqhathaniswa nezinye izinto zokwakha, okuwenza abe yinketho ekhangayo ekusebenzeni kwezikali ezincane noma ukugcina amanani amancane e-sodium cyanide. Iziqukathi ze-HDPE ziza ngobukhulu obuhlukahlukene kanye nokwakheka, okuhlanganisa izigubhu, amabhodlela, namathangi, okuhlinzeka ngokuguquguquka kwezinketho zokugcina.

I-Polypropylene (PP)

I-Polypropylene enye impahla yepulasitiki engasetshenziselwa ukugcina i-sodium cyanide. Inezici ezifanayo zokumelana namakhemikhali ku-HDPE futhi ilula futhi ihlala isikhathi eside. Iziqukathi ze-polypropylene zivame ukusetshenziselwa ukugcina izinhlobo eziqinile neziwuketshezi ze-sodium cyanide. Bangakwazi ukumelana nokushisa okuhlukahlukene, okuzuzisa ukugcinwa kwezimo ezihlukahlukene zemvelo. Njenge-HDPE, i-polypropylene ayisebenzi nge-sodium cyanide, iqinisekisa ukuqukatha okuphephile kwamakhemikhali.

Ingilazi - Insimbi Enomugqa

Ingilazi - iziqukathi zensimbi ezinomugqa zihlanganisa amandla ensimbi nokumelana kwamakhemikhali engilazi. Ingaphakathi lesitsha limbozwe ungqimba lwengilazi, olunikeza umgoqo ongenayo phakathi kwensimbi ne-sodium cyanide. Lokhu kwenza iziqukathi zensimbi ezinengilazi zimelane kakhulu nokugqwala nge-sodium cyanide. Zivame ukusetshenziselwa ukugcina imiqulu emikhulu ye-sodium cyanide emisebenzini yezimboni. Kodwa-ke, zibiza kakhulu kunezinye izinketho futhi zidinga ukuphathwa ngokucophelela ukuvimbela ukulimala kolwelwesi lwengilazi. Uma ulayini lwengilazi luklwetshiwe noma luqhekekile, lungafaka engozini ubuqotho besiqukathi futhi kuholele ekuvuzeni okungase kube khona noma ukusabela nge-substrate yensimbi.

I-Nickel - Alloys Asekelwe

Kwezinye izinhlelo zokusebenza ezikhethekile, ama-alloys asekelwe ku-nickel angasetshenziswa ukugcina i-sodium cyanide. Ama-alloys afana ne-Hastelloy ne-Inconel anikeza ukumelana nokugqwala okukhethekile ezindaweni zamakhemikhali ezinokhahlo, kuhlanganise nalezo ezihlanganisa i-sodium cyanide. Lawa ma-alloys angakwazi ukumelana namazinga okushisa aphezulu kanye nokusabela kwamakhemikhali anolaka kangcono kunezinye izinto eziningi. Nokho, ayabiza futhi angase angadingeki kuzo zonke izimo zokulondoloza. Ama-alloys asekelwe ku-nickel ngokuvamile asetshenziswa ezimbonini lapho izimo ezimbi kakhulu noma izidingo zesitoreji sesikhathi eside zidinga izinga eliphezulu kakhulu lokumelana namakhemikhali.

Idizayini Yesitsha nezici Zokuphepha

Kungakhathaliseki ukuthi iyiphi into ekhethiwe, iziqukathi zokugcina i-sodium cyanide kufanele zibe nezici ezithile zokuklama ukuthuthukisa ukuphepha. Zonke iziqukathi kufanele zivalwe ngokuqinile ukuze kuvinjelwe ukuphuma kwanoma iyiphi igesi ye-hydrogen cyanide engakhiqizwa ngenxa yokusabela komswakama noma okunye ukungcola. Kufanele futhi zenzelwe ukumelana nokuphathwa okuvamile nezingcindezi zokuhamba ngaphandle kokuqhekeka noma ukuvuza. Ukwengeza, iziqukathi kufanele zifakwe izinhlelo ezifanele zokukhipha umoya ukuze kuncishiswe noma yikuphi ukunqwabelana kwengcindezi okungenzeka ngesikhathi sokugcina. Lokhu kubaluleke kakhulu uma kungenzeka kube khona ukusabela kwamakhemikhali ngaphakathi kwesitsha esingase sikhiqize igesi.

Isiphetho

Ukukhetha into efanelekile yesiqukathi yokugcina i-sodium cyanide kubalulekile ekuqinisekiseni ukuphepha nokuvikela ukungcoliswa kwemvelo. Insimbi engagqwali, i-HDPE, i-polypropylene, ingilazi - insimbi enomugqa, kanye nama-alloys asekelwe ku-nickel konke okukhethwa kukho okusebenzayo, ngayinye inezinzuzo zayo nokucatshangelwa kwayo. Lapho ukhetha isiqukathi, kubalulekile ukucabangela izici ezifana nenani le-sodium cyanide okufanele ligcinwe, indawo yokugcina (okuhlanganisa izinga lokushisa, umswakama, namandla okuxhumana namanye amakhemikhali), kanye nezindleko. Ngokuhlola ngokucophelela lezi zici futhi zithobelane nezidingo zokulawula, izimboni zingagcina ngokuphephile i-sodium cyanide futhi zinciphise ubungozi obuhlobene naleli khemikhali enobuthi obuphezulu.
