I. Ngwa isi nke sodium Cyanide na ụlọ ọrụ eletrọnịkị

1.Metal elu ọgwụgwọ na Electroplating

Sodium cyanide bụ ihe dị mkpa na usoro Electroplating ọdịnala , ọkachasị n'imepụta bọọdụ sekit ebipụtara (PCBs) na njikọ, ebe a na-eji ya agwọ ọla dị ka ọla kọpa, ọlaedo, na ọlaọcha. Site na ọrụ mgbagwoju anya nke sodium cyanide, enwere ike nweta ndoputa otu ion ígwè, na-ahụ na njikọta na ike eletriki nke mkpuchi ahụ dị. Dịka ọmụmaatụ, na usoro metallization obere oghere nke PCBs dị elu, sodium cyanide nwere ike ijikwa ọnụego nkwụnye nke ọla kọpa nke ọma, na-ezere ntụpọ sekit dị mkpụmkpụ ma ọ bụ nke mepere emepe.

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 nwere nnukwu nsí (ọnụọgụ LD50 nke na-egbu egbu bụ naanị 6.4 mg/kg), ma ọ bụrụ na ị metụ uzuzu ma ọ bụ ihe ngwọta ya site na akpụkpọ ahụ, iku ume, ma ọ bụ iri ihe mberede nwere ike ibute ọnwụ. Ụlọ ọrụ eletrọniki kwesịrị inwe ngwa nchebe siri ike, usoro ọgwụgwọ mmiri mkpofu, na usoro nzaghachi mberede, nke na-ebute mmụba dị ukwuu na ọnụ ahịa ọrụ. Na mgbakwunye, ọtụtụ mpaghara gburugburu ụwa (dịka European Union na China) na-etinye usoro ikike maka iji cyanides , na-egbochi oke ojiji 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

Ka mmata zuru ụwa ọnụ gbasara nchekwa gburugburu ebe obibi na-abawanye, nlekọta nke Cyanide site n'aka mba dị iche iche gburugburu ụwa na-aghọwanye ihe siri ike. Dịka ọmụmaatụ, iwu REACH nke EU depụtara sodium cyanide dị ka ihe na-echegbu onwe ya nke ukwuu (SVHC), nke chọrọ ka ụlọ ọrụ nye ngwọta ndị ọzọ. Ọchịchọ ndị ahịa maka "ngwaahịa eletrọniki akwụkwọ ndụ akwụkwọ ndụ" na-amanyekwa ndị nrụpụta ka ha gbanwee gaa na usoro mmepụta dị nchebe.

III. Atụmatụ nzaghachi ụlọ ọrụ na Ọdịnihu Ọdịnihu

1.Technological Innovation: Imepe Green Alternative Usoro

• Teknụzụ Elektroplating Na-enweghị Cyanide : Ndị nchọpụta na-enyocha ojiji nke ihe ndị na-eme ka ihe dị mgbagwoju anya dị na bio (dịka chitosan) ma ọ bụ mmiri ionic iji dochie cyanide, na-ebelata nsí.

• Usoro Akọrọ : Iji teknụzụ akọrọ dịka ndoputa anwụrụ ọkụ (PVD) ma ọ bụ ndoputa anwụrụ ọkụ kemịkalụ (CVD) belata ịdabere na ihe ndị na-eme ka mmiri mmiri jupụta.

• Mmepụta Nka : Ime ka paramita electroplating ka mma site na algọridim AI iji belata ojiji nke sodium cyanide ebe ị na-eme ka mmepụta ngwaahịa ka mma.

2.Circular Economy and Resource Recycling

Ụlọ ọrụ eletrọnịkị na-eji nwayọọ nwayọọ ewebata usoro nlekọta mechiri emechi. A na-eji teknụzụ dị ka nkewa akpụkpọ ahụ na mgbanwe ion iji megharịa cyanides na ion metal n'ime mmiri ahịhịa, na-enwetaghachi ihe onwunwe. Dịka ọmụmaatụ, onye na-emepụta PCB na-ebute ụzọ enwetala ọnụọgụ nrụgharị sodium cyanide nke karịrị 90%, na-ebelata oke oriri na mmetọ.

3.Atumatu na Industrial Collaboration

Gọọmenti nwere ike ịgba ụlọ ọrụ ume ka ha nabata usoro ndụ akwụkwọ ndụ site na mkpali ụtụ isi, enyemaka R&D, na atumatu ndị ọzọ, ma n'otu oge ahụ kwalite nhazi ụkpụrụ ụlọ ọrụ (dịka "Usoro nchịkwa maka njikwa mmetọ nke ngwaahịa ozi eletrọnịkị kpatara"). Na mgbakwunye, ụlọ ọrụ dị na mgbago elu na mgbada nke agbụ ụlọ ọrụ (dị ka ndị na-ebubata ihe na ndị na-emepụta akụrụngwa) kwesịrị ime ka mmekorita sie ike ijikọ ọnụ mepụta ihe ngwọta ọzọ na-egbu egbu.
