Aha Dakeluo sitere n'ịkpọ na ịkpọ aha Bekee dacromet nkenke. Ndị ọrụ na-akpọkarị ya Dakeluo ma ọ bụ Dakexiu. N'obodo anyị, a na-akpọ ya mkpuchi zinc na chromium. Ọ bụ mkpuchi mgbochi nrụrụ kemịkal ọhụrụ nke isi ihe mejupụtara ya bụ ntụ zinc, ntụ aluminum, acid chromic na mmiri e wepụrụ ion na ya.

Aha Dakeluo sitere n'ịkpọ na ịkpọ aha Bekee dacromet nkenke. Ndị ọrụ na-akpọkarị ya Dakeluo ma ọ bụ Dakexiu. N'obodo anyị, a na-akpọ ya mkpuchi zinc na chromium. Ọ bụ mkpuchi mgbochi nrụrụ kemịkal ọhụrụ nke isi ihe mejupụtara ya bụ ntụ zinc, ntụ aluminum, acid chromic na mmiri e wepụrụ ion na ya. A pụrụ ikewaa ọrụ nchebe ya ụzọ atọ. Nke mbụ bụ mmetụta mgbochi: iberibe zinc na aluminum na-edobe n'elu ibe ha, na-egbochi mmiri, oxygen na ihe ndị ọzọ na-emebi ngwaahịa Dacromet iru ihe ntọala, si otú ahụ kee ihe mgbochi nchebe. Nke abụọ bụ passivation. N'oge ọgwụgwọ Dacromet, acid chromic na zinc, ntụ aluminum na ihe ntọala na-emeghachi omume, na-emepụta akwa passivation siri ike ma dị nso nke nwere ezigbo nguzogide nrụrụ kemịkal. Nke atọ bụ nchebe cathode. Ọrụ nchebe kachasị mkpa nke mkpuchi zinc, aluminum na chromium bụ ichebe ihe ntọala n'ụzọ cathode, dịka akwa zinc a na-etinye. Tụnyere usoro itinye ọla site na eletrik ọdịnala, a pụrụ ịgụ Dacromet dịka “itinye ọla na-echebe gburugburu”, nke nwere uru dịka nnukwu nguzogide nrụrụ kemịkal, enweghị ịdị agbaji sitere na hydrogen, nguzogide okpomọkụ dị elu, ezigbo ikike ịbanye n'ime oghere, ezigbo njide na ikike ịtinye mkpuchi ọzọ, enweghị mmetọ na enweghị mmerụ gburugburu. Mana “enweghị mmerụ gburugburu” a kpọtụrụ aha na-ezo aka naanị n'enweghị gas mkpofu na mmiri mkpofu n'oge mmepụta, na enweghị mkpa ịgwọ ụdị mkpofu atọ. Ọ pụtaghị na ọ dịghị mmerụ ọ bụla. Nke a bụ n'ihi na mkpuchi Dacromet nwere ụfọdụ chromium, nke nwere nsí nye mmadụ ma nwee ike ịkpata kansa, na-enwekwa nnukwu mmetụta nsí n'ihe ọkụkụ na ụmụ irighiri ndụ. Ya mere, mkpuchi Dacromet na-enweghị chromium aghọwo mkpa mmepe nke ọha mmadụ ugbu a na n'ọdịnihu. Naanị otú a ka a ga-esi belata ọzọ ma ọ bụ wepụ mmerụ nye gburugburu na mmadụ.

Iji belata ma ọ bụ wepụ chromium ka o kwere mee ma debe njirimara isi mkpuchi Dacromet, na ibelata ihe ize ndụ nwere ike ịpụta, ndị teknụzụ nyere mkpuchi Dacromet ọhụrụ na-enweghị chromium. Atụmatụ teknụzụ ya bụ mkpuchi nwere ntụ zinc, ntụ aluminom, ihe mgbaze, ihe enyemaka na ihe na-emepụta fim, tinyere tin. Pasent ibu ihe dị n'ime ya bụ ntụ zinc 20-30%, ntụ aluminom 5-10%, ihe mgbaze 20-30%, ihe enyemaka 5-10%, ihe na-emepụta fim 10-10%. N'ime nke a, mkpuchi Dacromet nwere pasent ibu ndị a: ntụ zinc 20-30%, ntụ aluminom 5-10%, diethylene glycol butyl ether 20-30%, n-butanol 5-10%, resin inorganic 10-20%, tin 5-10%. Ihe mgbaze bụ diethylene glycol butyl ether. Ihe enyemaka bụ n-butanol. Ihe na-emepụta fim bụ resin inorganic. Ntụ zinc dị n'ụdị akpụkpọ nta nwere dayameta micromita 5-25. Ntụ aluminom dịkwa n'ụdị akpụkpọ nta nwere dayameta micromita 5-25. Resin inorganic bụ ọkwa ụlọ ọrụ.

Tụnyere teknụzụ dị adị, mkpuchi Dacromet ọhụrụ a na-enweghị chromium nwere uru ndị a: nhazi emeziri jiri tin na ihe na-emepụta fim dochie chromic acid ọdịnala, wee zere ihe ize ndụ chromium. Tin n'onwe ya anaghị agba nchara, na-eguzogidekwa mmetọ mpụga ma nwee mgbanwe ụfọdụ, nke na-enyere usoro ịkpụzi mkpuchi Dacromet aka. Resin inorganic bụkwa ihe na-echebe gburugburu, na-eri obere ego ma nwee uru mgbasa dị elu.
