I-galvanizing ibhekiselele kubuchwephesha bonyango lomphezulu wokubeka umaleko we-zinc kumphezulu wesinyithi, i-alloy okanye enye into yokudlala i-aesthetic kunye nefuthe lokuthintela umhlwa.Eyona ndlela isetyenziswayo yi-galvanization yediphu eshushu.
IZinc inyibilika ngokulula kwiiasidi kunye nealkali, ngoko ibizwa ngokuba yintsimbi yeamphotropic.Izinc itshintsha kancinane kakhulu emoyeni owomileyo.Kumoya ofumileyo, ifilimu eshinyeneyo yealkaline zinc carbonate yenziwa kumphezulu wezinc. i-hydrogen sulfide kunye ne-Marine atmosphere, i-zinc corrosion resistance ayilunganga, ingakumbi kwiqondo lobushushu eliphezulu kunye nokufuma okuphezulu okuqulethe umoya we-asidi ye-organic, i-zinki yokwaleka kulula ukuyidla. Ubume be-electrode obuqhelekileyo be-zinc yi-0.76V, kwi-matrix yentsimbi, i-zinc yokugqoka i-coating ye-anodic, isetyenziselwa ukuthintela ukubola kwentsimbi, ukusebenza kwayo kokukhusela kunye nobukhulu bokugquma busondelene kakhulu. unyango lwe-passivation, ukuhlambalaza okanye ukugquma nge-arhente yokukhusela ukukhanya, kunokuphucula kakhulu ukukhuselwa kwayo kunye nokuhlobisa.
Ukugquma okubandayo
I-Cold galvanizing, ekwabizwa ngokuba yi-electrogalvanizing, kukusetyenziswa kwezixhobo ze-electrolytic emva kwe-oyile, i-pickling, ityuwa ye-zinc kwisisombululo, kunye nokudibanisa i-electrode engalunganga yesixhobo se-electrolytic, ngokuchasene nepleyiti ye-zinc, edityaniswe kwi-electrode echanekileyo ye-electrolytic. amandla izixhobo, usebenzisa langoku ukusuka elungileyo ukuya negative uya kudipozitha umaleko zinc kumbhobho, umbhobho yokucwenga ebandayo kuqhubekekiswa kuqala emva galvanizing.
Oomatshini bafakwe igalvanized
Kwigubu elijikelezayo elixhotyiswe ngeplating, ibhola yeglasi, umgubo we-zinc, amanzi kunye nomxhasi, ibhola yeglasi njengempembelelo ephakathi ijikeleza kunye negubu, ukukhuhlana kunye nehamile kumphezulu weplating ivelisa amandla asemzimbeni.Ngaphantsi kwesenzo somgqugquzeli weekhemikhali, i-zinc powder edibeneyo "i-welding ebandayo" kwindawo yokugubungela, eyenza i-coat, iyunifomu kunye nenkcazo ecacileyo kunye nobukhulu obuthile.
Ishushu-igalvanized
Eyona ndlela iphambili yokwenza ipleyiti yentsimbi igalele umphezulu yintsimbi eshushu.
Ukutshiza okushushu kwaphuhliswa kwiindlela zakudala kwaye kuneminyaka elikhulu elinamashumi asixhenxe ubudala ukusukela oko kwasetyenziswa kushishino ngo-1836.Nangona kunjalo, ushishino lwezinki olushushu luphuhliswe ngomyinge omkhulu kunye nophuhliso olukhawulezayo lwentsimbi eqengqelekayo eqengqelekayo. kule minyaka ingamashumi amathathu idlulileyo.
Inkqubo yokuvelisa ipleyiti eshushu amazinki ikakhulu ibandakanya: ipleyiti yoqobo pre-plating eshushu dip post-unyango egqitywe yokuhlolwa imveliso, etc.Ngokomkhwa, ngokwendlela yonyango yokwaleka ezahlukeneyo, inkqubo diphu galvanizing eshushu yahlulwe ngaphandle kumgca ngaphandle. kunye ne-annealing yangaphakathi yomgca we-annealing.
