Eletriki galvanized:
Steel dị mfe nchara na ikuku, mmiri ma ọ bụ ala, ma ọ bụ ọbụna mebie kpamkpam.Ọnwụ ígwè kwa afọ n'ihi corrosion na-akpata ihe dị ka 1/10 nke mmepụta ígwè dum.Tụkwasị na nke ahụ, iji nye elu ngwaahịa ígwè na akụkụ dị iche iche ọrụ pụrụ iche, mgbe ị na-enye ha ọdịdị mara mma, a na-emekarị ha site na electro-galvanizing.
① Ụkpụrụ:
Ebe ọ bụ na zinc adịghị mfe ịdịgasị iche na ikuku akọrọ, na ikuku iru mmiri, elu nwere ike ịmepụta ihe nkiri carbonate dị nnọọ ukwuu, nke nwere ike ichebe ime ya nke ọma, agaghịkwazi corrosion.
② Njirimara arụmọrụ:
1. Ihe mkpuchi zinc dị oke, na kristal dị mma, ịdị n'otu na enweghị porosity, yana ezigbo nguzogide corrosion;
2. The zinc oyi akwa enwetara site electroplating bụ dịtụ ọcha, na corrodes nwayọọ nwayọọ na alụlụ nke acid, alkali, wdg, na ike n'ụzọ dị irè na-echebe ígwè mkpụrụ;
3. Ihe mkpuchi zinc na-agafe chromic acid ka ọ bụrụ ọcha, agba, akwụkwọ ndụ akwụkwọ ndụ agha, wdg, nke mara mma na ịchọ mma;
4. N'ihi na mkpuchi zinc nwere ezigbo ductility, ọ nwere ike ịmepụta ya site na ịkụ ọkpọ oyi, ntụgharị, na-ehulata, wdg na-emebighị mkpuchi ahụ.
③ Oke ngwa:
Site na mmepe nke mmepụta sayensị na nkà na ụzụ, ubi ndị na-etinye aka na ụlọ ọrụ electroplating na-abawanye ụba.Ka ọ dị ugbu a, ngwa nke electro-galvanization agbasawo na ngalaba mmepụta na nyocha dị iche iche.
galvanized na-ekpo ọkụ:
ⅠNchịkọta:
N'ime usoro mkpuchi nke matrix ígwè dị iche iche na-echebe, ntinye ọkụ dị oke mma.Ọ bụ na steeti ebe zinc bụ mmiri mmiri, mgbe a dịtụ mgbagwoju physics, kemịkalụ, ọ bụghị naanị a thicker ọcha zinc oyi akwa bụghị naanị plated na ígwè, kamakwa a zinc-ferrous oyi akwa.Usoro plating a abụghị naanị nwere njirimara na-eguzogide corrosion nke eletriki galvanization, kamakwa n'ihi oyi akwa zinc iron alloy.Ọ nwekwara ike iguzogide zinc electroplated.Ya mere, nke a plating usoro kwesịrị ekwesị karịsịa maka a ike corrosive gburugburu ebe obibi dị ka a dịgasị iche iche nke siri ike acid, alkaline alụlụ.
ⅡỤkpụrụ:
Igwe galvanized na-ekpo ọkụ na-ekpo ọkụ bụ zinc na mmiri mmiri dị elu, a na-emepụta ya site na nzọụkwụ atọ:
1. A na-agbaze elu nke dabeere na ígwè site na ngwọta zinc iji mepụta usoro zinc-ferrous;
2. Zinc ion na alloy oyi akwa na-n'ihu diffused na mkpụrụ na-etolite a zinc ígwè intercollation oyi akwa;
3. A na-ejikọta elu nke ihe mkpuchi alloy na akwa zinc.
Ⅲ.Njirimara arụmọrụ:
(1) Nwere akwa akwa akwa akwa zinc dị ọcha na-ekpuchi n'elu nchara, nke na-ezere kọntaktị nke matrix ígwè site na ngwọta corrosion ọ bụla iji chebe matriks nchara site na corrosion.N'ime ikuku zuru oke, elu nke akwa zinc na-etolite akwa akwa akwa zinc oxide dị nro na nke na-akpachi anya, bụ nke siri ike ịme mmiri na mmiri, ya mere ígwè ígwè ahụ na-arụ ọrụ nchebe.
(2) Na ígwè-zinc alloy oyi akwa, jikọtara na ok, na mmiri nnu humex ikuku na ulo oru ikuku gosiri pụrụ iche corrosion iguzogide;
(3) Ebe ọ bụ na nchikota siri ike, zinc-iron na-solubilized, ọ nwere ike iyi na-eguzogide;
(4) Ebe ọ bụ na zinc nwere ezigbo ductility, ihe mkpuchi alloy na-ejikọta ya na otu nchara, ya mere akụkụ ndị na-ekpo ọkụ na-ekpo ọkụ nwere ike ịbụ oyi-plated, mpịakọta, brushed, curved, na ihe ndị ọzọ na-enweghị imebi mkpuchi;
(5) Mgbe galvanization na-ekpo ọkụ nke ígwè finisse, ọ dị ka ọgwụgwọ annealing, nke nwere ike imeziwanye ihe ndị na-arụ ọrụ nke ígwè ígwè matriks, wepụ nchekasị nke ịkpụzi ịgbado ọkụ, nke bara uru maka ịgbanye onye nhazi ígwè.
(6) Elu nke iberibe mgbe galvanization na-ekpo ọkụ na-egbuke egbuke ma mara mma.
(7) Igwe akwa zinc dị ọcha bụ akwa akwa galvanized plastik-plastic-plated na galvanized na-ekpo ọkụ, nke dị nso na zinc dị ọcha, ductility, ya mere ọ na-agbanwe.
ⅣOke ngwa:
Ngwa nke na-ekpo ọkụ na-ekpo ọkụ ghanelyly mmepe nke ụlọ ọrụ mmepụta ihe na ọrụ ugbo.Ya mere, ngwaahịa gared na-ekpo ọkụ bụ ụlọ ọrụ mmepụta ihe (dịka ngwá ọrụ kemịkal, nhazi mmanụ, nchọpụta mmiri, nhazi ígwè, nnyefe ọkụ eletrik, ụgbọ mmiri, wdg), ọrụ ugbo (dịka: ifesa), ihe owuwu (dị ka nnyefe mmiri na gas). waya set Tube, scaffolding, ụlọ, wdg), akwa mmiri, njem, wdg e ji mee ihe na a ọnụ ọgụgụ nke na-adịbeghị anya.
Ebe ọ bụ na ngwaahịa galvanized na-ekpo ọkụ na-ekpo ọkụ nwere ọdịdị mara mma, arụmọrụ na-eguzogide corrosion dị mma, ngwa ngwa ya na-abawanye ụba.
