Electrogalvanizing VS. I-Hot-dip Galvanizing

Ngokwezibalo, insimbi ilula ukugqwala emoyeni, emanzini okanye emhlabeni, kunye nelahleko yonyaka ebangelwa yi-akhawunti ye-corrosion malunga ne-1/10 yemveliso yensimbi epheleleyo. Ukuze wenze umphezulu we-fasteners ube nemisebenzi ekhethekileyo kwaye ubanike imbonakalo yokuhlobisa, ngokuqhelekileyo baphathwa nge-electrogalvanizing.

Electrogalvanizing

I-Electrogalvanizing yinkqubo efaka i-zinc coating kwintsimbi okanye intsimbi ngokusebenzisa umbane. Umgaqo ubandakanya ukucwiliswa kwenxalenye ukuba ifakwe kwisisombululo esinezinc ions. Xa umsinga wombane udlula kwi-electrolyte, i-zinc ions iyancitshiswa kumphezulu we-cathode, ibeka umaleko omncinci we-zinc ecocekileyo. Ubunzima kunye nokufana kwengubo kunokulawulwa ngokuchanekileyo ngokulungelelanisa ixesha lenkqubo, ukuxinana kwangoku, kunye nokubunjwa kwe-electrolyte. Le ndlela ivumela ukugqitywa okuqaqambileyo, okugudileyo, kunye nobuhle, kunye neengubo eziqhelekileyo ukusuka kwi-5 ukuya kwi-30 micrometers.

Iimpawu zokusebenza kweengubo zombane ze-electrogalvanized zibandakanya ukunamathela ngokugqwesileyo kwisiseko sesinyithi, ukubonelela ngokumelana ne-corrosion efanelekileyo, ngakumbi kwiindawo ezinobundlobongela obuncinci. Ubukhulu obufanayo kunye nokulawulwa buqinisekisa ukubonakala okuhambelanayo, okwenza kube yinto efanelekileyo kwiindawo apho kufuneka ukugqiba umgangatho ophezulu. Nangona kunjalo, ukugquma okucekethekileyo kuthetha ukuba i-electrogalvanizing ayinako ukubonelela ngenqanaba elifanayo lokhuseleko lomatshini njenge-galvanizing yediphu eshushu, kwaye inokuba sesichengeni somonakalo ovela kwi-abrasion kunye neempembelelo. Nangona kunjalo, inkqubo iyaziwa ngokukwazi ukuvelisa isohlwayo, kwanokwaleka okwandisa ukubukeka kwemveliso egqityiweyo.

Iinkalo ezibandakanyekayo kwi-electrogalvanizing ziya ziba zibanzi ngakumbi. Ukusetyenziswa kweemveliso ze-fastener kuye kwasasazeka kwimveliso yoomatshini, i-electronics, izixhobo ezichanekileyo, iikhemikhali, ezothutho, i-aerospace, njl., ezibaluleke kakhulu kuqoqosho lwelizwe.

I-Hot-dip galvanizing

I-Hot-dip galvanizing yinkqubo yokukhusela umhlwa apho intsimbi ecociweyo kwaye ilungisiwe okanye izakhi zentsimbi zintywiliselwa kwibhafu ye-zinc etyhidiweyo malunga ne-450 ° C (842 ° F). I-zinc iphendula ngentsimbi, yenze uluhlu lwezinki-iron alloy layers phezu kwentsimbi, ilandelwa ngumaleko we-zinc ecocekileyo. Le bhondi ye-metallurgical yenza i-coating ehlala kwaye ibambelele ngokuqinileyo. Ubukhulu bengubo ye-zinc buzilawula kwaye ngokubanzi buvela kwi-45 ukuya kwi-275 micrometers, kuxhomekeke kubukhulu bezinto ezisisiseko. Ixesha lokucwiliswa kunye nesantya sokupholisa emva kokususwa kwindawo yokuhlambela kunokuchaphazela ukubonakala kunye nokuthungwa kwengubo yokugqibela, edla ngokukhokelela kwipatheni ye-spangled okanye i-crystalline.

Iimpawu zokusebenza zeengubo ezishushu zediphu ziquka ukuqina okukhethekileyo kunye nokumelana nokubola kwexesha elide, elinokuhlala amashumi eminyaka nakwimimandla enzima. Ingqimba ye-zinc engqingqwa inika ukhuseleko oluluqilima kumonakalo owenziwe ngoomatshini, njengemikrwelo kunye ne-abrasions, kwaye isebenza njenge-anode yedini, i-corroding ekhethwayo ukukhusela intsimbi engaphantsi. I-coating nayo inokumelana nobushushu obuhle, nangona inokuchatshazelwa ngamaqondo aphezulu kakhulu. Ukubonakala kokuqala okukhanyayo, okwentsimbi ye-grey yengubo kuya kuba nesimo sezulu ngokuhamba kwexesha kwi-matte grey patina, engayithobeli iimpawu zayo zokukhusela. Ukongezelela, inkqubo ixabisa kakhulu kwizinto ezinkulu kunye ezinzima, njengoko inika isisombululo esihlala ixesha elide esifuna ukulungiswa okuncinci.

I-Hot-dip galvanizing isetyenziswa ngokubanzi kwizicelo ezahlukeneyo, ngakumbi ezo zibandakanya izakhiwo zangaphandle kunye neziseko zophuhliso, apho ukuvezwa kweempawu kubalulekile. Idla ngokusetyenziswa kwintsimbi yolwakhiwo, iibhulorho, iindlela zokugada uhola wendlela, iipali eziluncedo, kunye nezinye izinto zokwakha. Le ndlela ikwadume kakhulu ekwenzeni izixhobo zolimo, oomatshini boshishino, kunye neenkqubo zothutho, kuquka imizila kaloliwe kunye nezikhongozeli zokuthumela ngenqanawa. Ngenxa yesakhono saso sokubonelela ngesiphelo esiqinileyo, esihlala sihleli, kunye nokwamkeleka ngobuhle, igalvanizing eshushu yedip lukhetho olukhethwayo kuso nasiphi na isicelo esifuna ukhuseleko oluthembekileyo noluhlala ixesha elide ngokuchasene nomhlwa.
