Aikace-aikacen Sodium Cyanide a cikin Masana'antar Electroplating

Electroplating wani muhimmin tsari ne a masana'antar masana'antu, wanda ya haɗa da ajiye wani ɗan ƙaramin ƙarfe na bakin ciki akan saman kayan aikin ƙarfe ta hanyar lantarki. Wannan tsari ba wai kawai yana haɓaka juriya na lalata na ƙarfe ba amma kuma yana inganta yanayin kyawun sa da ingancin saman. Sodium cyanide, wani abu mai guba sosai amma mai yawan sinadarai, yana taka muhimmiyar rawa a cikin Girkawa masana'antu.

Tushen Electroplating

Electroplating dogara ne a kan ka'idar electrolysis. A cikin saitin na'urar lantarki, kayan aikin ƙarfe da za a sanyawa an sanya su ne cathode, yayin da ƙarfe da za a ajiye ana amfani da shi azaman anode. Dukansu cathode da anode suna nutsewa a cikin wani bayani na electrolyte wanda ya ƙunshi ions na ƙarfe na plating karfe. Lokacin da wutar lantarki ta wuce ta hanyar electrolyte, ions na ƙarfe a cikin bayani suna jawo hankalin cathode (workpiece) kuma an ajiye su a samansa, suna samar da bakin ciki, nau'i na nau'i na plating karfe.

Matsayin Sodium Cyanide a cikin Electroplating

Sodium cyanide (NaCN) ana amfani dashi ko'ina a cikin electroplating azaman a Wakilin Complexing. Yana da ikon samar da barga gidaje tare da ions karfe daban-daban. A cikin mahallin electroplating, waɗannan ƙarfe - cyanide complexes suna da fa'idodi da yawa:

1. Ingantattun Ingantattun Plating: Karfe - Cyanide complexes kafa ta sodium Cyanide taimako a cimma wani ƙarin uniform da santsi karfe shaida a kan workpiece surface. Alal misali, a cikin wutar lantarki na jan karfe, hadaddun jan karfe - cyanide yana tabbatar da cewa an ajiye ions na jan karfe daidai gwargwado, wanda ya haifar da wani nau'i mai yawa kuma mai ma'ana. Wannan yana da mahimmanci ga aikace-aikace inda mutuncin farantin da aka ɗora yana da mahimmanci, kamar a cikin masana'antar lantarki don sanya masu haɗawa.

2. Ingantaccen Rufewa: Amfanin sodium cyanide a cikin maganin electrolyte yana inganta ikon jefar da wanka na plating. Ƙarfin jifa yana nufin ikon plating bayani don saka wani uniform Layer na karfe a kan workpiece, ko da a kan hadaddun - siffa sassa tare da recesses da protrusions. Ƙarfe-cyanide complexes zai iya isa ga duk sassa na workpiece yadda ya kamata, yana tabbatar da cikakken ɗaukar hoto. Wannan yana da fa'ida sosai a masana'antu kamar kera motoci, inda sassan da ke da rikitattun geometries ke buƙatar a sanya su don kariya ta lalata.

3. Bargawar Plating Bath: Sodium cyanide yana taimakawa wajen kiyaye kwanciyar hankali na wanka na lantarki. Yana sarrafa ƙaddamar da ions ƙarfe na kyauta a cikin maganin, yana hana samuwar ajiyar ƙarfe wanda ba shi da kyau - manne ko rashin inganci. Ta hanyar samar da barga masu ƙarfi, yana ba da damar ƙarin sarrafawa da daidaiton tsari na lantarki.

Takamaiman Aikace-aikace na Sodium Cyanide a cikin Electroplating

1. Rufe Copper: A cikin electroplating na jan karfe, Sodium cyanide ana amfani da shi don samar da hadaddun jan karfe - cyanide. Wannan yana da mahimmanci musamman a lokacin da ake sakawa a kan abubuwan da ake amfani da su kamar su zinc - alloy die - simintin gyare-gyare. Zinc - alloy die - Ana amfani da simintin gyare-gyare sosai a masana'antar kayan ado, zippers, da ƙananan sassa na inji. Tun da zinc - gami yana da saukin kamuwa da lalata a cikin maganin plating acid, ana amfani da tsarin jan karfe na cyanide - tsarin plating sau da yawa azaman mataki na farko. Layer na jan karfe da aka ajiye ta amfani da cyanide - mai dauke da electrolyte yana kare sinadarin zinc - gami daga yanayin acidic na tsarin plating na gaba, kamar nickel plating, kuma yana inganta mannewar Layer nickel.

2. Plating Azurfa: Ana kuma amfani da sinadarin sodium cyanide wajen sarrafa wutar lantarki ta azurfa. Azurfa - cyanide complexes an kafa su a cikin electrolyte, wanda ke ba da damar ajiyar azurfa mai santsi da haske. Azurfa - abubuwan da aka ɗora ana amfani da su a cikin masana'antar kayan ado, kera kayan tebur, da lambobin lantarki. Amfani da sodium cyanide a cikin azurfa electroplating tabbatar da wani high - quality gama, tare da azurfa Layer da kyau kwarai reflectivity da lalata juriya.

3. Sanya zinc: Ko da yake an yi ƙoƙari don haɓaka hanyoyin da ba - cyanide zinc - tsarin plating ba, a wasu lokuta, ana amfani da wutar lantarki na cyanide - tushen zinc. Gilashin zinc - cyanide da aka kafa tare da taimakon sodium cyanide suna ba da ikon jefawa mai kyau kuma suna ba da izinin shigar da tukwane na tutiya na uniform. Zinc plating ana amfani da shi sosai don kariyar lalata ƙarfe da abubuwan ƙarfe, kamar a cikin gine-gine da masana'antar kera motoci.

La'akari da Lafiya

Duk da fa'idodi da yawa a cikin electroplating, sodium cyanide abu ne mai matuƙar guba. Yana sakin iskar hydrogen cyanide idan ya hadu da acid ko ruwa. Sabili da haka, dole ne a samar da tsauraran matakan tsaro a cikin wuraren da ake amfani da su na lantarki da ke amfani da sodium cyanide:

1. Kulawa da Ma'ajiya Mai Kyau: Sodium cyanide ya kamata a adana shi a cikin amintacce, wuri mai kyau, nesa da acid da danshi. Dole ne a horar da ma'aikatan da ke sarrafa sodium cyanide a cikin hanyoyin kulawa da kyau, gami da amfani da kayan kariya na mutum kamar safar hannu, tabarau, da kariyar numfashi.

2. Shirye-shiryen Amsa Gaggawa: Ya kamata tsire-tsire masu amfani da wutar lantarki su sami cikakkun tsare-tsare na amsa gaggawa idan akwai zubewar haɗari ko sakin sodium cyanide. Ya kamata waɗannan tsare-tsare sun haɗa da hanyoyin ƙaura daga yankin, kawar da cyanide, da ba da taimakon likita ga ma'aikatan da abin ya shafa.

3. Kariya na muhalli: Ruwan datti daga hanyoyin sarrafa lantarki da ke ɗauke da sodium cyanide dole ne a kula da shi yadda ya kamata don cire cyanide kafin a fitar da shi cikin muhalli. Hanyoyin magani na iya haɗawa da sinadarai oxidation, wanda ke canza cyanide zuwa ƙananan mahadi masu cutarwa.

A ƙarshe, sodium cyanide yana taka muhimmiyar rawa a cikin masana'antar lantarki, yana ba da damar samar da samfura masu inganci, masu ɗorewa, da ƙayatarwa. Koyaya, dole ne a kula da amfani da shi a hankali don tabbatar da amincin ma'aikata da kare muhalli. Kamar yadda fasaha ta ci gaba, ana ƙoƙarin haɓaka madadin, ƙananan matakai masu guba don electroplating, amma a halin yanzu, sodium cyanide ya kasance muhimmin sashi a yawancin aikace-aikacen lantarki.
