Izikhongozeli eziKhuselekileyo zokuGcina iSodium Cyanide

Sodium i-cyanide yikhompawundi yeekhemikhali eziyityhefu kakhulu kwaye enobungozi esetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zemizi-mveliso, njengokutsalwa kwegolide kunye nesilivere, i-electroplating, kunye ne-chemical synthesis. Ngenxa yobutyhefu obugqithisileyo kunye nokubakho komngcipheko wokusingqongileyo kunye nokhuseleko, ukugcinwa okufanelekileyo kubaluleke kakhulu. Ukukhetha ekunene Izinto zokugcina ngumba obalulekileyo wokuqinisekisa ukuphathwa ngokukhuselekileyo kunye nokubanjwa Isodium cyanide. Eli nqaku liphonononga iintlobo zezixhobo ezinokuthi zisetyenziswe ngokukhuselekileyo ukugcina Isodium cyanide.

Ukuqonda iiPropati zeSodium Cyanide

I-sodium cyanide (NaCN) imhlophe, i-soluble water-soluble solid or powder kunye ne-almond ekrakra-njengevumba. Isebenza kakhulu kwaye inokubangela umngcipheko omkhulu. Xa idibana namanzi, iiasidi, okanye iintsimbi ezithile, inokukhupha igesi yehydrogen cyanide, enetyhefu egqithisileyo kwaye enokubulala nakwindawo encinci. Ukongezelela, i-ejenti yokunciphisa eyomeleleyo kwaye inokusabela ngobundlobongela kunye ne-oxidizing agents. Ezi zakhiwo zifuna ukuba izikhongozeli zokugcina zikhethwe ngononophelo ukuthintela nakuphi na ukusabela okungafunekiyo kunye nokuqinisekisa ukuthembeka kwezinto ezigciniweyo. sodium cyanide.

Iimfuno zoLawulo lweSodium Cyanide Storage

Ngaphambi kokuba uphonononge kwimathiriyeli yesikhongozeli esifanelekileyo, kubalulekile ukuba uqaphele inkqubo-sikhokelo yolawulo elawula ukugcinwa kwesodium cyanide. Kumazwe amaninzi, kukho imigaqo engqongqo yokulawula ukuphathwa, ukugcinwa, nokuthuthwa kwale nto iyingozi. Le migaqo ihlala ichaza iimfuno malunga noyilo lwesikhongozeli, iilebhile, kunye nokuhambelana nemichiza. Umzekelo, izikhongozeli kufuneka zibhalwe ngokucacileyo njengezinesodium cyanide, kunye nezilumkiso ezifanelekileyo zengozi. Ukuthotyelwa kwale mimiselo akuyomfuneko yomthetho kuphela kodwa kukwabalulekile ekugcineni ukhuseleko kwindawo yokusebenza nokukhusela okusingqongileyo.

Izinto ezifanelekileyo zesikhongozeli

Yenziwe ngentsimbi eshayinayo

Insimbi engenasici lukhetho oludumileyo lokugcina i-sodium cyanide, ngakumbi kwiindawo zoshishino. IBakala 304 kunye ne-316 iintsimbi ezingenasici zisetyenziswa ngokuqhelekileyo. Intsimbi engatyiwayo inika ukuxhathisa okugqwesileyo kokutya, nto leyo ibalulekileyo njengoko izisombululo zesodium cyanide zinokugqwesa, ngakumbi xa kukho ukufuma. Isiqulatho sechromium kwintsimbi engenasici senza umaleko we-oxide we-passive kumphezulu, uthintela isinyithi ukuba singasabeli ngecyanide. Nangona kunjalo, kubalulekile ukuba uqaphele ukuba insimbi engenasici ayinakufaneleka ukugcina i-sodium cyanide kuzo zonke iimeko. Kwiindawo ezine-acidic kakhulu okanye xa udibana nokungcola okuthile, ukuxhathisa kwe-corrosion yensimbi engenasici kunokuphazamiseka. Ukuhlolwa rhoqo kwee-stainless-container zetsimbi zeempawu zokubola ziyimfuneko ukuze kuqinisekiswe ukuthembeka kwazo okuqhubekayo.

I-Polyethylene eNxina kakhulu (HDPE)

Izikhongozeli zeHDPE zikwasetyenziswa kakhulu ukugcina i-sodium cyanide. I-HDPE yipolymer ye-thermoplastic enokumelana neekhemikhali ezilungileyo, kuquka ukuxhathisa kwiikhemikhali ezininzi ezifana ne-sodium cyanide. Ikhaphukhaphu, ukanti yomelele kwaye yomelele. Izikhongozeli ze-HDPE azinakuphinda zisebenze kunye ne-sodium cyanide phantsi kweemeko eziqhelekileyo zokugcina, okwenza kube yinto ekhuselekileyo. Zikwangabizi kakhulu xa kuthelekiswa nezinye izinto, nto leyo ezenza zibe lukhetho olunomtsalane kwimisebenzi emincinci okanye yokugcina imiyinge emincinci yesodium cyanide. Izikhongozeli ze-HDPE ziza ngobukhulu obuhlukeneyo kunye neemilo, kubandakanywa amadubhu, iibhotile kunye namatanki, ukubonelela ukuguquguquka kwiinketho zokugcina.

Iipolypropylene (PP)

Ipolypropylene yenye imathiriyeli yeplastiki engasetyenziselwa ukugcina i-sodium cyanide. Ineempawu ezifanayo zokumelana neekhemikhali kwi-HDPE kwaye ilula kwaye iqinile. Izikhongozeli zePolypropylene zihlala zisetyenziselwa ukugcina zombini iindlela eziqinileyo kunye nezilulwelo zesodium cyanide. Ziyakwazi ukumelana noluhlu olubanzi lwamaqondo okushisa, oluyinzuzo yokugcina kwiimeko ezahlukeneyo zokusingqongileyo. Njenge-HDPE, i-polypropylene ayisebenzi kunye ne-sodium cyanide, iqinisekisa ukugcinwa okukhuselekileyo kweekhemikhali.

Iglasi - Intsimbi enemigca

Iglasi - izikhongozeli zetsimbi ezinemigca zidibanisa amandla entsimbi kunye nokumelana neekhemikhali zeglasi. Umgangatho wangaphakathi wesitya ufakwe kwiglasi yeglasi, enika umqobo we-inert phakathi kwentsimbi kunye ne-sodium cyanide. Oku kwenza ukuba izikhongozeli zentsimbi ezineglasi zikwazi ukumelana nomhlwa yisodium cyanide. Zihlala zisetyenziselwa ukugcina umthamo omkhulu we-sodium cyanide kwizicelo zamashishini. Nangona kunjalo, zibiza kakhulu kunezinye iinketho kwaye zifuna ukuphathwa ngononophelo ukuthintela umonakalo kwilayini yeglasi. Ukuba i-glass lining ikrwelwe okanye iqhekeziwe, inokuthi ibeke esichengeni intembeko yesikhongozeli kwaye ikhokelele ekuvuzeni okunokwenzeka okanye ukusabela nge-substrate yentsimbi.

I-Nickel-based Alloys

Kwezinye izicelo ezikhethekileyo, i-nickel-based alloys ingasetyenziselwa ukugcina i-sodium cyanide. I-alloys ezifana ne-Hastelloy kunye ne-Inconel zibonelela ngokumelana ne-corrosion ekhethekileyo kwiindawo ezinobume bekhemikhali ezirhabaxa, kubandakanywa nezo zibandakanya i-sodium cyanide. Ezi ngxubevange ziyakwazi ukumelana nobushushu obuphezulu kunye neekhemikhali ezinobunkunkqele zokusabela ngcono kunezinye izinto ezininzi. Nangona kunjalo, zibiza kakhulu kwaye zisenokungabi yimfuneko kuzo zonke iimeko zokugcina. I-nickel-based alloys idla ngokusetyenziswa kumashishini apho iimeko ezinzima okanye iimfuno zokugcina ixesha elide zifuna inqanaba eliphezulu lokuxhathisa imichiza.

Uyilo lwesikhongozeli kunye neempawu zoKhuseleko

Kungakhathaliseki ukuba yintoni into ekhethiweyo, izitya zokugcina i-sodium cyanide kufuneka zibe neempawu ezithile zokuyila ukunyusa ukhuseleko. Zonke izikhongozeli kufuneka zitywinwe ngokuqinileyo ukuthintela ukubaleka kwayo nayiphi na igesi yehydrogen cyanide enokuthi iveliswe ngenxa yeentshukumo zokufuma okanye ezinye izinto ezingcolisayo. Kufuneka kwakhona ziyilelwe ukumelana nokuphathwa okuqhelekileyo kunye noxinzelelo lwezothutho ngaphandle kokuqhekeka okanye ukuvuza. Ukongeza, izikhongozeli kufuneka zixhotyiswe ngeenkqubo ezifanelekileyo zokukhupha umoya ukuphelisa naluphi na uxinezeleko olunokuthi lwenzeke ngexesha logcino. Oku kubaluleke ngakumbi ukuba kunokwenzeka ukuba kubekho ukusabela kweekhemikhali ngaphakathi kwesikhongozeli esinokuvelisa igesi.

isiphelo

Ukukhetha imathiriyeli efanelekileyo yokugcina i-sodium cyanide kubalulekile ekuqinisekiseni ukhuseleko kunye nokuthintela ukungcoliseka kwendalo. Insimbi engenasici, i-HDPE, i-polypropylene, i-glass-lined steel, kunye ne-nickel-based alloys yizo zonke iinketho ezinokubakho, nganye ineenzuzo zayo kunye nokuqwalaselwa kwayo. Xa ukhetha i-container, kubalulekile ukuqwalasela izinto ezifana nobuninzi be-sodium cyanide ekufuneka igcinwe, indawo yokugcina (kubandakanya ubushushu, ukufuma, kunye nokudibana nezinye iikhemikhali), kunye neendleko. Ngokuphonononga ngononophelo ezi zinto kunye nokuthobela iimfuno zolawulo, amashishini anokugcina ngokukhuselekileyo i-sodium cyanide kwaye anciphise iingozi ezinxulumene nale khemikhali inetyhefu kakhulu.
