Electro galvanizing
Inkcazelo emfutshane:
I-Electro galvanizing: ekwaziwa ngokuba yi-galvanizing ebandayo kushishino, yinkqubo yokwenza iyunifomu, intsimbi eshinyeneyo kunye nebotshwe kakuhle okanye ialloy deposition layer kumphezulu weworkpiece nge electrolysis.
Xa ithelekiswa nezinye iintsimbi, i-zinc inexabiso eliphantsi kwaye kulula ukuyicoca.Lixabiso eliphantsi anti-corrosion electroplated ukutyabeka.Isetyenziselwa kakhulu ukukhusela intsimbi kunye neengxenye zetsimbi, ngokukodwa ukukhusela ukubola kwe-atmospheric, kunye nokuhlobisa.Itekhnoloji yokucoca ibandakanya i-bath plating (okanye i-hanging plating), i-barrel plating (efanele iindawo ezincinci), i-blue plating, i-automatic plating kunye ne-continuous plating (efanele i-wire kunye ne-strip).
uphawu
Injongo ye-electro galvanizing kukuthintela izinto zetsimbi ukuba zingatshatyalaliswa, ukuphucula ukunyanzeliswa kwe-corrosion kunye nobomi benkonzo yensimbi, kunye nokwandisa ukubonakala kokuhlobisa kweemveliso.Intsimbi iya kuthotywa yimozulu, amanzi okanye umhlaba ngokunyuka kwexesha.E-China, i-corrod steel akhawunti malunga nesinye seshumi somthamo wensimbi yonke ngonyaka.Ngoko ke, ukwenzela ukukhusela ubomi benkonzo yentsimbi okanye iinxalenye zayo, i-electro galvanizing isetyenziselwa ukucubungula isinyithi.
Ngenxa yokuba i-zinc akulula ukuyitshintsha emoyeni owomileyo kwaye inokuvelisa ifilimu eyisiseko ye-zinc carbonate kwindawo enomswakama, le filimu inokukhusela iindawo zangaphakathi kumonakalo wokubola.Nangona i-zinc layer yonakaliswa ngezinye izinto, i-zinc kunye nentsimbi iya kudibanisa ukwenza ibhetri encinci emva kwexesha elithile, ukwenzela ukuba i-matrix yensimbi ibe yi-cathode kwaye ikhuselwe.Kugqitywe ekubeni i-electro galvanizing inezi mpawu zilandelayo:
Inokumelana ne-corrosion elungileyo, indibaniselwano entle kunye nefanayo, kwaye akukho lula ukungenwa ngerhasi enomhlwa okanye ulwelo.
Ngenxa yokuba umaleko we-zinc usulungekile, akukho lula ukugrunjwa kwi-asidi okanye kwindawo yealkali.Ukukhusela ngokufanelekileyo umzimba wentsimbi ixesha elide.
Ingasetyenziswa ngemibala eyahlukeneyo emva kwe-chromate passivation.Inokukhethwa ngokokuthanda kwabathengi.I-galvanizing intle kwaye ihombisa.
I-coating ye-zinc ine-ductility enhle kwaye ayiyi kuwa lula ngexesha lokugoba, ukuphatha kunye nempembelelo.
