Koj puas paub txog kev siv sodium cyanide?

Txawm hais tias sodium cyanide muaj tshuaj lom heev los, nws yog ib yam khoom siv tseem ceeb uas siv tau rau ntau yam lag luam. Tsab xov xwm no tsom mus rau kev piav qhia txog nws cov kev siv.

1. Kev lag luam electroplating

Hauv kev siv tshuab electroplating, Sodium cyanide ua lub luag haujlwm tseem ceeb hauv cov chaw da dej electroplating rau cov hlau xws li tooj liab, nyiaj, cadmium, thiab zinc. Nws ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo ntawm cov txheej electroplated, pab ua kom tiav cov khoom sib xws thiab cov khoom sib txuas. Lub peev xwm ua kom sib xyaw ntawm cyanide ions nrog cov hlau ions hauv cov tshuaj plating tso cai rau kev tswj hwm zoo dua ntawm cov txheej txheem deposition, ua rau cov txheej electroplated du thiab tiv taus corrosion ntau dua.

2. Mechanical Industry

Rau kev lag luam kho tshuab, Sodium Cyanide yog siv los ua tus neeg sawv cev rau ntau hom hlau. Quenching yog ib qho txheej txheem kho cua sov t

ha tuaj yeem txhim kho qhov tawv, lub zog, thiab kev hnav tsis kam ntawm cov hlau. Los ntawm kev siv sodium cyanide hauv cov khoom siv quenching, cov khoom siv kho tshuab ntawm cov hlau tuaj yeem hloov kho kom raug kom ua tau raws li qhov xav tau ntawm ntau yam khoom siv kho tshuab, xws li iav, ncej, thiab cov kabmob.

3. Kev lag luam metallurgical

Ib qho ntawm cov kev siv paub zoo ntawm sodium cyanide yog nyob rau hauv kev rho tawm cov hlau zoo li kub thiab nyiaj. Nyob rau hauv cov txheej txheem cyanidation, sodium cyanide reacts nrog kub los yog nyiaj nyob rau hauv lub ore los ua soluble hlau - cyanide complexes. Cov complexes tuaj yeem raug cais tawm ntawm cov ore matrix, thiab cov hlau muaj txiaj ntsig tau rov qab los ntawm kev siv tshuaj lom neeg lossis electrochemical ntxiv. Txoj kev no tau siv dav hauv kev lag luam mining vim nws cov txiaj ntsig zoo hauv kev rho tawm cov hlau muaj txiaj ntsig los ntawm qib qis ores.

4. Kev lag luam tshuaj

Sodium cyanide yog ib yam khoom siv tseem ceeb hauv kev lag luam tshuaj rau kev tsim ntau yam inorganic cyanides . Piv txwv li, nws yog siv los ua potassium cyanide, calcium cyanide, thiab lwm yam cyanide compounds. Tsis tas li ntawd, nws yog ib qho tseem ceeb precursor rau kev tsim hydrogen cyanide, uas yog ib qho tseem ceeb hauv kev tsim ntau yam organic tshuaj, xws li acrylonitrile, adiponitrile, thiab ntau yam cyanide-muaj polymers.

5. Dye Industry

Hauv kev lag luam dyeing, sodium cyanide koom nrog hauv kev tsim khoom ntawm 三聚氰氯 (cyanuric chloride). Cyanuric chloride yog ib qho tseem ceeb nruab nrab ntawm cov synthesis ntawm ntau yam reactive dyes, uas yog dav siv nyob rau hauv textile dyeing vim lawv zoo heev xim ceev ceev thiab kaj xim. Cov tshuaj tiv thaiv ntawm sodium cyanide nrog rau lwm yam tshuaj nyob rau hauv ib tug series ntawm cov txheej txheem ua rau lub tsim ntawm cyanuric chloride, uas ces koom nyob rau hauv ntxiv tshuaj tiv thaiv los tsim cov dyes molecules.

6. Kev lag luam kws tshuaj

Kev lag luam kws tshuaj kuj ua rau siv sodium cyanide. Nws yog ua hauj lwm nyob rau hauv lub synthesis ntawm tej yam tshuaj intermediates, xws li methyl cyanoacetate thiab diethyl malonate. Cov intermediates no tseem ceeb heev rau kev tsim cov tshuaj ntau yam, suav nrog qee cov tshuaj tua kab mob, tshuaj tiv thaiv kab mob siab, thiab cov tshuaj antineoplastic. Cov tshuaj tiv thaiv tshwj xeeb uas muaj cov sodium cyanide hauv cov tshuaj synthesis yog ua tib zoo tswj xyuas kom zoo thiab kev nyab xeeb ntawm cov khoom siv tshuaj zaum kawg.

7. Kev lag luam Textile

Hauv kev lag luam textile, sodium cyanide muaj ntau yam haujlwm. Nws tuaj yeem siv los ua mordant, uas pab cov dyes ua raws li cov ntaub ntawv zoo dua qub, txhim kho cov xim nrawm thiab xim qhov tob ntawm dyed fabrics. Ntxiv mus, nws kuj yog siv rau hauv cov kua carburizing thiab nitriding txheej txheem ntawm hlau. Cov kua carburizing thiab nitriding tuaj yeem txhim kho qhov tawv tawv thiab hnav - ua haujlwm ntawm cov khoom siv hlau siv hauv tshuab textile, ua kom cov haujlwm du thiab kev ua haujlwm ntev ntawm cov tshuab.

Hauv kev xaus, sodium cyanide, txawm tias nws toxicity, plays lub luag haujlwm tseem ceeb hauv ntau lub lag luam. Txawm li cas los xij, vim nws cov tshuaj toxicity siab, nruj kev nyab xeeb thiab kev tiv thaiv ib puag ncig yuav tsum tau ua raws li thaum lub sijhawm tsim khoom, khaws cia, kev thauj mus los, thiab siv los tiv thaiv kev puas tsuaj rau tib neeg kev noj qab haus huv thiab ib puag ncig.
