Isikhokelo esiBanzi kwi-Sodium Cyanide: Ukuthengwa, uThutho, kunye neeNqaku eziPhambili zobuGcisa

Intshayelelo: Sodium Cyanide 

Sodium i-cyanide, njengento ebalulekileyo ekrwada kwindawo yoshishino, isetyenziswa kakhulu kumashishini afana nemigodi yegolide, i-electroplating, kunye namayeza. Nangona kunjalo, ubutyhefu bayo obuphezulu kunye nokubola okunamandla kuyenza ibe yikhemikhali esemngciphekweni omkhulu. Singathenga njani ngokukhuselekileyo, sithuthe, kwaye sisebenzise Isodium cyanide phantsi kwemeko yokuthotyelwa? Eli nqaku liza kukunika isikhokelo sobuchwephesha ukusuka kumbono wenkqubo epheleleyo ukukunceda uphephe imingcipheko kunye nokuqinisekisa ukhuseleko lwemveliso.

I. Ukuthengwa kweSodium Cyanide

1. Cacisa iNjongo yokuThenga kwaye Uphelise usetyenziso olungekho mthethweni

Isodium cyanide yikhemikhali eyityhefu kakhulu elawulwa ngokungqongqo ngurhulumente. Ukusetyenziswa ngokusemthethweni yeyona nto ifunekayo ukuze kuthengwe. Umzekelo:

• Ukumbiwa kweGolide: Isetyenziswe kwinkqubo ye-cyanidation leaching yokukhutshwa kwegolide;

• Umzi mveliso wokwenza i-Electroplating: Njengommeli wonyango wesinyithi;

• Uphando lweLebhu: Isetyenziswe kwiimvavanyo ezithile zemichiza.

Amanyathelo aphambili:

• Ukubonelela ngezatifikethi zesiqinisekiso seshishini (ilayisensi yeshishini, ilayisenisi yemveliso, njl.);

• Ngenisa inkcazo eneenkcukacha yosetyenziso kunye nesicwangciso sobungakanani;

• Yamkela uphononongo lokuthotyelwa kwamasebe afanelekileyo.

2. Isikrini ababoneleli abasemthethweni kunye noLawulo lwemingcipheko kuMthombo

Kubalulekile ukukhetha abaniki-nkonzo abasesikweni abanelayisenisi yokushishina ngemichiza eyingozi. Uyakwazi ukusikrini ngokusebenzisa la majelo alandelayo:

• Amaqonga agunyazisiweyo: anjengeZiko lokuRhweba leMichiza yaseTshayina kunye neqonga le-e-commerce leekhemikhali eziyingozi;

• Iingcebiso kuShishino: Qhagamshelana noontanga bakho okanye imibutho yoshishino ukuze ufumane uluhlu lwababoneleli abathembekileyo.

Amanqaku oQinisekiso:

• Amaxwebhu esiqinisekiso somthengisi (ilayisensi yeshishini, isiqinisekiso sokhuseleko, njl.);

• Imigangatho yomgangatho wemveliso (efana ne-GB19268-2023 Specification for Packaging of Solid Cyanides).

3. Ukulungiswa kweMpatho yeSicelo: Iinkcukacha zimisela iMpumelelo okanye ukungaphumeleli

Iimfuno zokuvunywa kwe Ukuthengwa kweSodium Cyanide ziyahluka kancinci kwimimandla eyahlukeneyo, kodwa ezi zixhobo zilandelayo zihlala zifunwa ukuba zingeniswe:

• Isicelo sokuthenga (kubandakanywa ukusetyenziswa, ubuninzi, iimeko zokugcina);

• Inkqubo yolawulo lokhuseleko lweshishini kunye nesicwangciso sokusabela kwimeko kaxakeka;

• Izatifikethi zoqeqesho lokhuseleko lwamachiza kubasebenzi.

II. Ukuthuthwa kweSodium Cyanide

1. Izixhobo zoThutho kunye neNgcaciso yokuPakisha

• ISodium Cyanide eqinile: Sebenzisa iveni evaliweyo. Ukupakishwa kufuneka kuhambelane nomgangatho we-GB19268-2023, kwaye iilebhile ezilumkisayo ezifana "netyhefu kakhulu" kunye "ne-corrosive" kufuneka ziphawulwe;

• Ulwelo lweSodium Cyanide: Sebenzisa ilori yetanki ekhethekileyo. Isikhongozeli kufuneka singanyangeki kuxinzelelo kwaye singavuzi, kwaye sixhotyiswe ngesixhobo sokunqanda unxunguphalo.

2. Amanyathelo oKhuseleko lwezoThutho

• Ukuchongwa kwemoto: Xhoma uphawu lothutho lwempahla eyingozi kwaye ufake inkqubo yokubeka iGPS;

• Ulwabiwo lwabasebenzi: Ukulawulwa yikhapha eqinisekisiweyo kulo lonke uhambo, kwaye ukuthuthwa komntu oyedwa akuvumelekanga;

• UCwangciso lweNdlela: Gwema iindawo ezixineneyo kunye neendawo zokukhusela umthombo wamanzi, kwaye uqhube ngexesha elichaziweyo.

3. Isicwangciso sokuPhendula ngoNgxamiseko: Zilungiselele iimeko zikaNgxamiseko

• Unyango lokuvuza: Phuma isihlwele ngokukhawuleza, yimboze ngesanti okanye i-soda ash, kwaye ungayichukumisi ngokuthe ngqo;

• Impendulo yoMlilo: Sebenzisa isicima somlilo esomileyo kwaye ugweme ukudibanisa ne-nitrate kunye ne-acids;

• UQeqesho rhoqo: Lungiselela i-drill yokulinganisa ingozi yezothutho kanye ngekota ukuphucula amandla okuphendula ngokukhawuleza.

III. Isikhokelo sobuGcisa seSodium Cyanide: Ukusetyenziswa okuKhuselekileyo kunye nokuPhendula ngeNgozi

1. UKhuseleko loBuqu kunye neNgcaciso yokuSebenza

• Izixhobo Ezikhuselayo: Nxiba isuti enye echasene netyhefu, iiglavu zerabha, kunye nemaski echasene netyhefu enobuso obugcweleyo;

• Inkqubo yokusebenza:

• Ukulinganisa ngokuchanekileyo idosi ukuphepha inkcitho;

• Coca ngokucokisekileyo izixhobo emva kokusebenza ukuthintela iintsalela;

• Akuvumelekanga ukutya, ukusela, okanye ukutshaya kwindawo yotyando.

2. UkuPhathwa kweeNgozi eziNgxamisekileyo

• Ukutyhefa kwabasebenzi:

1. Dlulisela kwindawo yokuphefumula ngokukhawuleza kwaye ugcine umgudu wokuphefumula ungaphazamiseki;

2. Faka i-3% ye-sodium nitrite (10-15ml) + i-25% isisombululo se-glucose (40ml);

3. Emva koko faka i-50% ye-sodium thiosulfate (20-50ml) yokukhupha.

• Ukuvuza kokusingqongileyo:

• Vala isiza kwaye unciphise izinto ezine-asidi ngekalika;

• Qokelela izinto ezivuzayo kwaye uphathise iziko lobungcali ukuba lizichithe.

isiphelo

Ukuthengwa, ukuthuthwa, kunye nokusetyenziswa kwe sodium cyanide ziiprojekthi ezicwangcisiweyo ezifuna ukuqhutywa ngengqikelelo "yokuthintela kuqala, indibaniselwano yothintelo kunye nolawulo". Ngophononongo olungqongqo lwesiqinisekiso, ukusebenza ngokusemgangathweni, kunye nokulungela unxunguphalo, amashishini akakwazi nje ukunika umdlalo opheleleyo kwixabiso leshishini lemveliso. Isodium cyanide kodwa kwanokunciphisa iingozi zokhuseleko ngowona mlinganiselo mkhulu.
