Hauv kev npaj ntawm semiconductor wafers, kev tu saum npoo yog qhov tseem ceeb kom tshem tawm cov kab mob thiab xyuas kom muaj kev sib raug zoo ntawm cov txheej txheem tom ntej. Sodium cyanide-raws li kev daws teeb meem tuaj yeem ua haujlwm los xaiv cov hlau tsis huv lossis cov khoom seem ntawm qhov chaw wafer, yog li txhim kho qhov zoo thiab kev ua haujlwm ntawm cov khoom siv semiconductor. Txawm li cas los xij, muab cov kev cai huv huv thiab huv huv hauv kev tsim khoom semiconductor, kev siv sodium cyanide yuav tsum tau ua tib zoo tswj thiab ua raws li cov txheej txheem ntxuav kom huv thiab tshem tawm kom tsis txhob muaj cov kab mob sib kis ntawm cov khoom siv semiconductor.

Qhov zoo ntawm Kev Siv Sodium Cyanide

Kev siv sodium cyanide hauv kev lag luam hluav taws xob muaj ntau qhov zoo. Ua ntej, nws lub peev xwm los tsim cov hlau ruaj khov ua kom muaj kev tswj xyuas zoo dua ntawm cov tshuaj tiv thaiv, uas ua rau muaj kev tsim khoom zoo sib xws thiab txhim khu kev qha. Qhov kev sib xws no yog qhov tseem ceeb rau kev tsim cov khoom siv hluav taws xob zoo nrog cov yam ntxwv ua tau zoo.

Thib ob, sodium cyanide-raws li cov txheej txheem feem ntau muab cov hlau zoo tshaj plaws thiab ua tiav saum npoo piv rau lwm cov tshuaj. Cov khaubncaws sab nraud povtseg thiab tsis muaj qhov tsis xws luag ua tiav los ntawm cyanide electroplating tuaj yeem txhim kho cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob, pab txhawb kev ua haujlwm tag nrho thiab lub neej ntawm cov khoom siv.

Kev pheej hmoo thiab kev xav txog kev nyab xeeb

Txawm hais tias nws cov txiaj ntsig, sodium cyanide ua rau muaj kev pheej hmoo loj vim nws cov tshuaj lom heev. Txawm tias me me, raug rau sodium cyanide tuaj yeem ua rau tuag taus vim nws inhibits cellular respiration los ntawm kev khi rau cytochrome oxidase, tiv thaiv cov hlwb los ntawm kev siv oxygen. Hauv qhov chaw tsim khoom siv hluav taws xob, cov txheej txheem kev nyab xeeb nruj yuav tsum nyob hauv qhov chaw los tiv thaiv kev nqus pa, tiv thaiv daim tawv nqaij, lossis kev noj cov tshuaj sodium cyanide.
