Inkqubela phambili kwimveliso ye-sodium cyanide ukusuka ekuqhekekeni kweoli ekhanyayo e-China

intshayelelo

The Inkqubo yokuqhekeka kweoli ekhanyayo kuba Isodium cyanide imveliso kudala enye yeendlela eziphambili e-China, accounting phezu 60% umthamo wemveliso iyonke Isodium cyanide elizweni. Kwiminyaka yakutshanje, kunye neenzame zikarhulumente wase-China eziqinisiwe kwimveliso yokhuseleko lweekhemikhali eziyingozi kunye nokubekwa kweliso kokusingqongileyo, uphuculo olubonakalayo luye lwabonwa kuzo zombini izikali zezixhobo zemveliso kunye nokulunga kokusingqongileyo kule nkqubo yemveliso.

Ukuqhubela phambili kwisiGaba seMveliso kunye nokuLungelana nokuSingqongileyo

Ezinkudlwana - Izibonelelo zeMveliso yesiKhala

Umlinganiselo wemveliso yenkqubo yokuqhekeka kweoli ekhanyayo iye yanda. Kusakhiwa izityalo ezinkulu, ezinganyusi nje ukusebenza kakuhle kwemveliso kodwa zikwavumela ulawulo olungcono lwemithombo. Olu fakelo lwemilinganiselo emikhulu luyilwe ngeengqikelelo zobunjineli eziphucukileyo, ziqinisekisa inkqubo yokuvelisa ezinzileyo neqhubekayo. Umzekelo, izityalo zanamhlanje zinamagumbi okusabela alungeleyo anokuphatha umthamo omkhulu we-oyile ekhanyayo kunye ne-reactants, ekhokelela kwizivuno eziphezulu. sodium cyanide.

Ukomelezwa kokuSingqongileyo

Ukucuthwa "kweNkunkuma eziNtathu"

Ngokwamkelwa kobuchwepheshe obuphambili kunye nezixhobo, isixa "senkunkuma emithathu" (inkunkuma yegesi, amanzi amdaka, kunye nenkunkuma eqinileyo) eyenziwe ngexesha lenkqubo yokuvelisa iyancipha kakhulu. Ii-reactors zokuqhekeka kwesizukulwana esitsha zixhotyiswe ngegesi ephuculweyo - iinkqubo zokucoca. Ezi nkqubo zinokususa ngokufanelekileyo iigesi eziyingozi njengehydrogen i-cyanide kunye neeoksidi zenitrogen ezivela kwigesi yokukhupha, ukunciphisa ungcoliseko lomoya. Ngokumalunga nokucocwa kwamanzi amdaka, ukuhluzwa okuphezulu kunye neendlela zokunyanga iikhemikhali zisetyenziswa. Amanzi amdaka avela kwinkqubo yokuvelisa aphathwa ukuze ahlangabezane nemigangatho engqongqo yokusingqongileyo ngaphambi kokuba akhululwe, ukunciphisa impembelelo kwimithombo yamanzi. Ngokumalunga nenkunkuma eqinileyo, iinkqubo ezintsha ziye zaphuhliswa ukuze kusetyenziswe ngokutsha okanye ukulahla ngokukhuselekileyo iimveliso zendalo, nto leyo enciphisa ngakumbi ubume bendalo esingqongileyo.

Ukugcinwa kobutyebi

Ukugcinwa kwemithombo kwakhona ibe yinto ephambili yenkqubo ephuculweyo yokuqhekeka kweoli. Ubushushu obuphezulu - iinkqubo zokubuyisela zifakwe kwizityalo zokuvelisa zanamhlanje. Ezi nkqubo zinokubamba kwaye ziphinde zisebenzise ubushushu obuveliswa ngexesha lenkqubo yokuqhekeka, ukunciphisa ukusetyenziswa kwamandla ngokubanzi. Ukongeza, ii-catalysts ezisebenzayo ngakumbi ziyasetyenziswa, ezingakhawulezi nje ukukhawulezisa izinga lokusabela kodwa ziphucule izinga lokusetyenziswa kwemathiriyeli ekrwada. Ngenxa yoko, i-oyile encinci yokukhanya kunye nezinye i-reactants ziyadingeka ukuvelisa umlinganiselo ofanayo we-sodium cyanide, ukufezekisa ukugcinwa kwemithombo ebalulekileyo.

Impembelelo yeMimiselo eQilileyo

Ukuqiniswa kokhuseleko kunye nemithetho yokusingqongileyo ibe yeyona nto iphambili ekuphuculeni oku. Urhulumente waseTshayina ukhuphe uluhlu lwemigaqo-nkqubo kunye nemigangatho yokuqinisekisa ukuveliswa okukhuselekileyo kweekhemikhali ezinobungozi kunye nokukhusela indalo. Amashishini emveliso kufuneka atyale imali kubuchwepheshe obuphambili kunye nezixhobo zokuhlangabezana nezi mfuno zolawulo. Ukungathobeli kusenokukhokelela kwizohlwayo eziqatha, kuquka izohlwayo, ukumiswa kwemveliso, okanye ukuvalwa kweshishini. Ke ngoko, ukuze kugcinwe ukukhuphisana kwabo kunye nophuhliso lwexesha elide, amashishini alwamkele ngenkuthalo uphuculo lwetekhnoloji kunye nokuphuculwa kwenkqubo.

isiphelo

Ukuqukumbela, inkqubo yokuqhekeka kweoli ekhanyayo ye Ukuveliswa kwe-sodium cyanide e-China kuye kwenzeka utshintsho oluphawulekayo kwiminyaka yakutshanje. Ukuphuculwa komlinganiselo wemveliso kunye nobuhlobo bendalo esingqongileyo, kunye nolondolozo lwemithombo, ayizompendulo kuphela kuxinzelelo lolawulo kodwa nokubonakaliswa kwephulo loshishino lophuhliso oluzinzileyo. Njengoko itekhnoloji iqhubela phambili kwaye iimfuno zolawulo ziba ngqongqo ngakumbi, kulindeleke ukuba le nkqubo yemveliso iqhubeke nokuvela, ifikelela kumanqanaba aphezulu okhuseleko, ukhuseleko lokusingqongileyo, kunye nokusetyenziswa kobutyebi.
