I. Ngwa isi nke sodium Cyanide na ụlọ ọrụ eletrọnịkị

1.Metal elu ọgwụgwọ na Electroplating

Sodium cyanide bụ ihe dị mkpa na omenala Eletriki usoro, karịsịa na n'ichepụta nke e biri ebi sekit mbadamba (PCBs) na njikọ, ebe ọ na-eji maka elu ọgwụgwọ nke ọla dị ka ọla kọpa, gold, na ọlaọcha. Site na ihe mgbagwoju anya nke sodium cyanide, a na-enweta ntinye nke ion metal nke otu, na-eme ka nkwekọrịta na eletrik eletrik nke mkpuchi. Dịka ọmụmaatụ, n'ime usoro nhazi micro-hole nke PCB dị elu, sodium cyanide nwere ike ịchịkwa ọnụ ọgụgụ nke ọla kọpa nke ọma, na-ezere nhụsianya mkpirisi mkpirisi ma ọ bụ oghere oghere.

2.Semiconductor Device Manufacturing

Na mmepụta mgbawa semiconductor, a na-eji sodium cyanide mee ihe maka nhicha na etching nke elu wafer. Dị ka ọmụmaatụ, mgbe silicon wafer polishing, sodium cyanide ngwọta nwere ike wepu metal fọdụrụnụ na-egbochi mkpirisi okirikiri. Na mgbakwunye, enwere ike iji ihe na-ebelata ike ya maka ọgwụgwọ elu nke ụfọdụ semiconductors (dị ka GaAs), na-emeziwanye arụmọrụ ngwaọrụ.

3.Battery na Energy Nchekwa Technology

Na njikọ nke ihe electrode dị mma maka batrị lithium-ion na batrị nickel-metal hydride batrị, enwere ike iji sodium cyanide mee ihe dị ka ihe mgbagwoju anya iji nyere aka ịhazi morphology na nha nha nke metal precursors, si otú ahụ kwalite ikike batrị na ndụ okirikiri. Dịka ọmụmaatụ, na usoro nkwadebe nke ihe electrode ternary positive (dị ka NCM), mmeghachi omume nchikota nke metụtara sodium cyanide nwere ike ịkwalite nkesa ahụ.

4.Ezigharị ihe mkpofu eletrọnịkị

N'ịgwọ ihe mkpofu eletrọnịkị, enwere ike iji sodium cyanide mee ka ọla dị oke ọnụ ahịa dị ka ọla edo na ọlaọcha si na bọọdụ sekit . Ikike mgbagwoju anya ya na-enyere ọla ndị dị oke ọnụ ahịa kewaa n'ụdị nke cyanide complexes, na-eme ka ọ dị ọcha na-esote.

II. Ihe ịma aka nka na nka na gburugburu ebe obibi chere ihu na Sodium Cyanide

1.High toxicity Risk na Safety Control

Sodium cyanide na-egbu egbu nke ukwuu (ihe dị n'etiti LD50 na-egbu egbu bụ naanị 6.4 mg/kg), na kọntaktị na uzuzu ya ma ọ bụ ihe ngwọta ya site na akpụkpọ ahụ, iku ume, ma ọ bụ ntinye na mberede nwere ike ịnwụ. Ụlọ ọrụ eletrọnịkị kwesịrị inwe ngwa nchebe siri ike, usoro ọgwụgwọ mmiri mkpofu, na usoro mmeghachi omume mberede, na-ebute mmụba dị ukwuu na ụgwọ ọrụ. Na mgbakwunye, ọtụtụ mpaghara gburugburu ụwa (dị ka European Union na China) mejuputa usoro ikike maka ojiji nke cyanides, na-amachikwa oke ngwa ya.

2. Mmetọ gburugburu ebe obibi na ihe egwu gburugburu ebe obibi

Ọ bụrụ na a na-ewepụ mmiri mkpofu nke nwere cyanide ozugbo na-enweghị ọgwụgwọ nke ọma, hydrogen cyanide (HCN) ga-emepụta site na ire ere n'ime mmiri anụ ahụ, na-etinye ihe ize ndụ nye ihe ndị dị ndụ na mmiri na ahụike mmadụ. Usoro ọgwụgwọ ọdịnala (dị ka usoro alkaline chlorination) chọrọ nnukwu ihe oxidants ma nwee ike mepụta mmetọ nke abụọ (dịka ngwaahịa sitere na chlorine). Ya mere, ụlọ ọrụ eletrọnịkị kwesịrị itinye ego dị elu n'ịwulite ụlọ ọrụ ọgwụgwọ mmiri dị elu.

3.Technical bottlenecks nke nnọchi

Ọ bụ ezie na teknụzụ electroplating na-enweghị cyanide (dị ka iji ihe mgbagwoju anya dị ka EDTA na citrates) enweela ọganihu, ha enweghị ike dochie anya sodium cyanide zuru oke n'ihe gbasara àgwà mkpuchi (dị ka otu na adhesion) na nhazi usoro. Dịka ọmụmaatụ, itinye teknụzụ ntinye ọla edo na-enweghị cyanide na njikọ elektrọn ka nwere nsogbu nke nguzogide kọntaktị dị oke elu, nke na-egbochi nkwalite ya.

4.Regulatory na Social Pressures

Na-amụba zuru ụwa ọnụ mmata nke gburugburu ebe obibi, nlekọta nke Cyanides site na mba dị iche iche n'ụwa na-aghọwanye ndị siri ike. Dịka ọmụmaatụ, ụkpụrụ EU's REACH depụtara sodium cyanide dị ka ihe nwere oke nchegbu (SVHC), na-achọ ka ụlọ ọrụ nye ụzọ ọzọ. Ọchịchọ ndị ahịa chọrọ "ngwaahịa eletrọnịkị na-acha akwụkwọ ndụ akwụkwọ ndụ" na-amanyekwa ndị na-emepụta ihe ka ha gbanwee gaa na usoro mmepụta dị nchebe.
