Kushandiswa kweSodium Cyanide muIndasitiri Yemagetsi

Mukukurumidza kushanduka indasitiri yemagetsi, zvinhu zvakasiyana-siyana zvemakemikari zvinoita basa rinokosha mukugadzira. Pakati pavo, sodium cyanide (NaCN), kunyangwe ine muchetura zvakanyanya, yakawana chaiyo uye yakakosha mashandisirwo nekuda kweiyo yakasarudzika makemikari zvimiro. Iyi blog positi inoongorora mukushandiswa kwakasiyana kwe Sodium Cyanide mukati mechikamu chemagetsi, kuratidza mabasa ayo, zvakanakira, uye njodzi dzakabatana.

Chemical Properties uye Reactivity yeSodium Cyanide

Sodium cyanide ivhu jena, rakasimba rekristaro rinonyungudika zvakanyanya mumvura. Reactivity yaro inobva pakuvapo kweiyo cyanide ion (CN⁻), iyo inoumba magadzirirwo akagadzikana ane simbi dzakawanda. Hunhu uhwu hunoita kuti ive chinhu chakakosha mukugadzirisa makemikari akawanda, kunyanya ayo anosanganisira kugadzirwa kwesimbi - chinhu chakakosha pakugadzira magetsi.

Electroplating: A Primary Application

Imwe yeanonyanya kuzivikanwa maapplication e Sodium cyanide muindasitiri yemagetsi iri mukati electroplating. Electroplating inzira yekuisa simbi yakatetepa pane substrate uchishandisa magetsi. Muchirevo chechinyorwa chino, sodium cyanide inoshanda seyakaomesesa mumiriri mumabhati e electroplating.

Kana ichishandiswa mugoridhe, sirivha, uye copper electroplating, sodium cyanide inoumba yakagadzikana metal-cyanide complexes. Aya macomplexes anodzora kuburitswa kwesimbi ion mubhati re electroplating, kuve nechokwadi cheyunifomu uye yepamusoro-mhando yesimbi kuiswa pamusoro pezvinhu zvemagetsi. Semuyenzaniso, mukugadzirwa kwezvibatanidza, maswichi, uye akadhindwa edunhu mabhodhi (PCBs), chidimbu chitete chegoridhe kana sirivheri plating chinogona kuwedzera conductivity, kuderedza ngura, uye kugadzirisa kusimba kwese kwezvikamu. Kushandiswa kwesodium cyanide mumabhati e electroplating inobvumira kunyatso kudzora pamusoro pekukora uye kuumbwa, kusangana nezvinoda kuomesesa zveindasitiri yemagetsi.

Semiconductor Kugadzira

Sodium cyanide inoitawo basa mune zvimwe zvikamu zvekugadzira semiconductor. Kunyangwe iyo semiconductor indasitiri inonyanya kuvimba neakasiyana siyana emakemikari akasarudzika uye maitiro, sodium cyanide inogona kushandiswa mune mamwe pre-kurapa uye kuchenesa matanho.

Mukugadzirira kwema semiconductor wafers, kucheneswa kwepamusoro kwakakosha kubvisa zvinosvibisa uye kuve nechokwadi chekunamatira kwakakodzera kwezvikamu zvinotevera. Sodium cyanide-based solutions inogona kushandiswa kunyungudutsa tsvina yesimbi kana zvisaririra pamusoro pewafer, nekudaro ichivandudza kunaka uye kushanda kwemidziyo yesemiconductor. Nekudaro, zvichipihwa hutsanana hwakasimba uye kuchena zvinodiwa mukugadzira semiconductor, kushandiswa kwesodium cyanide kunofanirwa kudzorwa nekuchenjerera uye kuteverwa nekunyatsosuka uye decontamination maitiro kudzivirira chero kusvibiswa kunogona kuitika kweanonzwisa semiconductor zvinhu.

Zvakanakira Kushandisa Sodium Cyanide

Kushandiswa kwesodium cyanide muindasitiri yemagetsi kunopa zvakati wandei zvakanakira. Chekutanga, kugona kwayo kuumba yakagadzika simbi complexes inogonesa kutonga kuri nani pamusoro pekuita kwemakemikari, zvichikonzera kuenderana uye kwakavimbika maitiro ekugadzira. Kusawirirana uku kwakakosha pakugadzira zvigadzirwa zvemagetsi zvemhando yepamusoro zvine maitiro akafanana ekuita.

Kechipiri, sodium cyanide-yakavakirwa maitiro anowanzo kupa epamusoro simbi kuiswa uye kupedzisa kwepamusoro zvichienzaniswa nemamwe makemikari. Iwo akatsetseka uye asina hurema-isina simbi akaturikidzana anowanikwa kuburikidza necyanide electroplating anogona kukwidziridza emagetsi uye emuchina zvivakwa zvemagetsi zvikamu, zvichibatsira mukushanda kwese uye hupenyu hwezvishandiso.

Njodzi uye Dziviriro Kufunga

Pasinei nemabhenefiti ayo, sodium cyanide inoisa njodzi dzakakura nekuda kwekunyanyisa kwayo muchetura. Kunyangwe mune zvidiki zvishoma, kuratidzwa kune sodium cyanide kunogona kuuraya sezvo ichidzivirira kufema kwemasero nekusunga ku cytochrome oxidase, kudzivirira masero kubva kushandisa oxygen. Munzvimbo yekugadzira zvemagetsi, mapuroteni akasimba ekuchengetedza anofanirwa kunge ari munzvimbo yekudzivirira inhalation, kubata ganda, kana kupinza sodium cyanide.

Zvivako zvekugadzira zvinobata sodium cyanide zvinofanirwa kuve nematanho akazara ekuchengetedza, anosanganisira akakodzera masystem emhepo, midziyo yekudzivirira yevashandi (PPE) yevashandi, uye zvirongwa zvekupindura emergency. Pamusoro pezvo, kutonga kwemarara kwakakosha kuve nechokwadi chekuti marara ane sodium cyanide inobatwa uye kuraswa zvakachengeteka kudzivirira kusvibiswa kwezvakatipoteredza. Nekuda kwenjodzi idzi, kune kukura kuri kuita muindasitiri kutsvaga mamwe makemikari nematanho anogona kuwana mhedzisiro yakafanana pasina huturu hwakabatana.

Zveramangwana Remangwana

Nekushushikana kuri kuwedzera pamusoro pezvakatipoteredza uye kuchengetedzeka kwevanhu, indasitiri yemagetsi inogara ichitsvaga dzimwe nzira dzakachengeteka kune sodium cyanide. Kuedza kutsvagisa kwakanangana nekugadzira isiri-cyanide electroplating yekugezera uye nzira dzekurapa dzepamusoro dzinogona kupa mashandiro akafanana. Semuyenzaniso, mamwe asiri ecyanide plating tekinoroji anoshandisa organic complexing agents kana mamwe makemikari maumbirwo kuti awane simbi deposition.

Nekudaro, kutsiva sodium cyanide zvachose inoramba iri dambudziko nekuda kweiyo yakasarudzika zvivakwa yainopa. Mune ramangwana rinoonekwa, nepo kushandiswa kwesodium cyanide kungaderera, zvinokwanisika kuramba uine niche kuvapo muindasitiri yemagetsi, kunyanya mumashandisirwo ayo mabhenefiti ekuita kwakaoma kudzokorora nezvimwe zvinhu. Vagadziri vanozoda kuenzanisa pakati pekusimudzira mabhenefiti esodium cyanide uye kuita kuchengetedzwa kwakasimba uye kuchengetedzwa kwezvakatipoteredza.

Mukupedzisa, sodium cyanide yakaita mupiro wakakura kuindasitiri yemagetsi kuburikidza nekushandisa kwayo mukugadzira electroplating uye semiconductor. Nepo huturu hwayo huchida kungwarira kubata uye kwakasimba kuchengetedza mapuroteni, yakasarudzika makemikari zvimiro zvakaita kuti ive chinhu chakakosha mune mamwe maitiro ekugadzira. Sezvo indasitiri ichienda kune mamwe maitiro akasimba uye akachengeteka, remangwana resodium cyanide mumagetsi rinoenderana nekuvandudzwa kwedzimwe nzira dzinoshanda uye kugona kubata njodzi dzakabatana nemazvo.
