Iposwe kwi 2018-11-12I-Dacromet coating, eyaziwa ngokuba yi-zinc flake coating, inenzuzo yokuba le yokugqibela ayinakufezekiswa xa kuthelekiswa ne-electro galvanized kunye ne-hot dip galvanizing techniques.Ukwaleka kwe-zinc flake kunezi nzuzo zilandelayo:
#1.Ukumelana nomhlwa okungaqhelekanga
Ukukhuselwa kwe-electrochemical elawulwayo ye-zinc, impembelelo yokukhusela i-zinc / i-aluminium sheets kunye ne-self-repairing effect ye-chromate yenza ukuba i-Dacromet yokugqoka ixhathise kakhulu kwi-corrosion xa i-Dacromet yokugqoka ivavanywa kwi-spray yetyuwa engathathi hlangothi.Kuthatha malunga neeyure ezili-100 ukukhwela i-1um yokwambathisa, ephindwe ka-7-10 engcono kunonyango lwendabuko lwegalvanizing.Uvavanyo olungathathi hlangothi lwesitshizi setyuwa lunokuhlala ngaphezulu kweeyure ze-1000 (ukwambathisa ngobunzima be-8um okanye ngaphezulu), kwaye enye nangaphezulu, oku akunakwenzeka ngeeleya zegalvanized kunye nediphu eshushu.
#2.Ukumelana nobushushu obugqwesileyo
Ekubeni i-polymer ye-chromic acid e-Dakoro ayinayo amanzi e-crystal kunye ne-melting point ye-aluminium / i-zinc sheet iphezulu, i-coating ine-high-temperature resistance corrosion resistance.Ingubo ye-Dacromet inobushushu bokumelana nokushisa kwe-300 ° C. Ingasetyenziselwa ngokuqhubekayo ixesha elide kwi-250 ° C. Ukuxhatshazwa kwayo kwe-corrosion kuphantse kuchaphazeleke, kwaye ifilimu ye-passivation ebusweni bomgangatho we-zinc ye-electroplated ichithwa ngeenxa zonke. I-70 ° C, kwaye ukuxhathisa ukubola kukuhla ngokukhawuleza.
#3.Akukho brittleness ye-hydrogen
Ngethuba lokunyangwa kwezobugcisa be-Dacromet, akukho kuhlamba i-asidi, i-electrodeposition, i-electric de-oiling, njl., kwaye akukho mpendulo ye-electrochemical ye-hydrogen evolution ebangelwa yinkqubo ye-electro-galvanizing, ngoko ke izinto eziphathekayo aziyi kubangela ukukhutshwa kwe-hydrogen.Ngoko ke ifanelekile ngokukodwa ukuphatha iindawo ezilastiki kunye nezixhobo zokusebenza zamandla aphezulu.
#4.Ukulungelelaniswa kakuhle
Ukubonakala kwengubo yeDacromet yisilivere-grey kunye nokubambelela kakuhle kwi-substrate kunye neengubo ezahlukeneyo.Ingasetyenziselwa njengoluhlu oluphezulu okanye njenge-primer yeengubo ezahlukeneyo.Iimpendulo ze-Electrochemical zenzeka phakathi kwesinyithi ngenxa yomahluko onokuthi ubekho.Kwimigangatho yegalvanized, zombini i-iron-based kunye ne-aluminium-based layers ziyakwazi ukumelana ne-electrochemically kwaye zinciphisa kakhulu ukuxhathisa ukubola.Kwi-Dacromet anti-corrosion layer, ekubeni i-anti-corrosion isekelwe kwi-chromic acid passivation kunye nokulawulwa kwedini lokukhuselwa kwe-scaly zinc layer, akukho mhlwa we-electrochemical wenziwa, ngoko ukusetyenziswa kwe-Zn kugxininisekile kwi-corrosion ye-Al icinezelwe.
#5.Permeability egqwesileyo
I-Dacromet yonyango lwe-fluid inokungena kwi-tight joint of the workpiece ukuze yenze i-rust-proof coating.Ukuba indlela yokusetyenziswa kwe-electroplating isetyenzisiweyo, indawo yangaphakathi yelungu le-tubular ayinzima kakhulu ngenxa yempembelelo yokukhusela.Nangona kunjalo, ngenxa yokuba unyango lwe-Dacromet lusetyenziswa ngokutyabeka kwaye lukwazi ukungena kakuhle, lunokusetyenziswa ekuphuculeni amandla okuthintela umhlwa ngaphakathi nangaphandle.
#6.Akukho ungcoliseko
Xa i-electroplating zinc, kukho ingxaki yokukhutshwa kwamanzi amdaka aqukethe i-zinc, i-alkali, i-chromic acid, njl., eya kubangela ukungcola okukhulu.Ubushushu be-zinc dip eshushu buphezulu, kwaye umphunga we-zinc okhutshiweyo kunye ne-HCL ziyingozi kwimpilo yabantu.Uninzi lwemveliso ye-zinc eshushu yangoku kufuneka iqhutywe kude neendawo zasedolophini nasezilalini.Inkqubo yeDacromet yenze intsimi entsha yokukhusela isinyithi.Ngenxa yokuba unyango lwe-Dacromet luyinkqubo evaliweyo, izinto eziguquguqukayo ngexesha lokubhaka ikakhulu zimanzi, aziqukethe ezinye izinto ezinobungozi ezilawulwayo, kwaye azikho ukungcoliswa kwendalo.
