Kuthunyelwe ku 2018-11-12I-Dacromet coating, eyaziwa nangokuthi i-zinc flake coating, inenzuzo yokuthi lokhu kokugcina akukwazi ukufezwa uma kuqhathaniswa namasu avamile okugcoba ama-electro galvanized kanye ne-hot dip galvanizing.I-Zinc flake coating inezinzuzo ezilandelayo:
#1.Ukumelana nokugqwala okungajwayelekile
Ukuvikelwa kwe-electrochemical okulawulwayo kwe-zinc, umphumela wokuvikela wamashidi we-zinc/aluminium kanye nomthelela wokuzilungisa we-chromate kwenza i-Dacromet coating imelane kakhulu nokugqwala lapho ukufakwa kwe-Dacromet kuhlolwa kusifutho sikasawoti esingathathi hlangothi.Kuthatha cishe amahora angu-100 ukunamathisela i-1um yokugqoka, engcono izikhathi ezingu-7-10 kunokwelashwa okujwayelekile kokufaka ama-galvanizing.Ukuhlolwa kwesifutho sikasawoti okungathathi hlangothi kungahlala amahora angaphezu kuka-1000 (ukumbozwa ngogqinsi oluyi-8um noma ngaphezulu), kanti okunye kuphakeme kakhulu, lokhu akwenzeki ngezingqimba ezifakwe uthayela nediphu elishisayo.
#2.Ukumelana nokushisa okuhle kakhulu
Njengoba i-polymer ye-chromic acid e-Dakoro-coated ingenawo amanzi ayikristalu futhi iphuzu lokuncibilika kweshidi le-aluminium/zinc liphezulu, ukumboza kunokumelana nokugqwala okuhle kakhulu kwezinga lokushisa.I-Dacromet yokugqoka inokushisa kokumelana nokushisa kwe-300 ° C. Ingasetshenziswa ngokuqhubekayo isikhathi eside ku-250 ° C. Ukumelana kwayo nokugqwala cishe akuthinteki, futhi ifilimu ye-passivation ebusweni bengqimba ye-zinc electroplated ibhujiswa nxazonke. 70 ° C, futhi ukumelana nokugqwala kwehla kakhulu.
#3.Ayikho i-hydrogen brittleness
Ngesikhathi sokwelashwa kwezobuchwepheshe kwe-Dacromet, akukho ukugeza kwe-asidi, i-electrodeposition, i-electric de-oiling, njll., futhi akukho ukusabela kwe-electrochemical of hydrogen evolution okubangelwa inqubo ye-electro-galvanizing, ngakho-ke impahla ngeke ibangele i-hydrogen embrittlement.Ngakho-ke ifaneleka ngokukhethekile ukuphatha izingxenye ezinwebekayo kanye nama-workpieces anamandla aphezulu.
#4.I-goodrecoatability
Ukubonakala kwe-Dacromet coating isiliva-grey ngokunamathela okuhle ku-substrate kanye nezingubo ezihlukahlukene.Ingasetshenziswa njengesendlalelo esiphezulu noma njenge-primer yezingubo ezihlukahlukene.Ukusabela kwe-electrochemical kwenzeka phakathi kwezinsimbi ngenxa yomehluko ongaba khona.Ezingqimbeni ezifakwe uthayela, zombili izingqimba ezisekelwe ku-iron nezisekelwe ku-aluminium azikwazi ukumelana namakhemikhali e-electrochemical futhi zinciphisa kakhulu ukumelana nokugqwala.Okwe-Dacromet anti-corrosion layer, njengoba i-anti-corrosion isekelwe ku-chromic acid passivation kanye nokuvikelwa komhlatshelo okulawulwayo kongqimba lwe-scaly zinc, akukho ukugqwala kwe-electrochemical okukhiqizwa, ngakho-ke ukusetshenziswa kwe-Zn kucindezelwe ukugqwala kwe-Al kucindezelwe.
#5.I-permeability enhle kakhulu
Uketshezi lokwelapha lwe-Dacromet lungangena ekuhlanganyeleni okuqinile kwendawo yokusebenza ukuze kwakheke ukugqwala okungangeni.Uma indlela ye-electroplating isetshenziswa, indawo engaphakathi yelungu le-tubular ayigxiliwe neze ngenxa yomphumela wokuvikela.Kodwa-ke, ngenxa yokuthi ukwelashwa kwe-Dacromet kusetshenziswa ngokugqoka futhi kunokungena kahle, kungasetshenziswa ukuthuthukisa ikhono lokuvimbela ukugqwala ngaphakathi nangaphandle.
#6.Akukho ukungcola
Lapho i-electroplating zinc, kunenkinga yokukhipha indle equkethe i-zinc, i-alkali, i-chromic acid, njll., okuzodala ukungcola okukhulu.Izinga lokushisa le-hot dip zinc liphezulu, kanti umhwamuko we-zinc okhululiwe kanye ne-HCL kuyingozi empilweni yomuntu.Iningi lokukhiqizwa kwe-zinc yokushisa kwamanje kufanele kwenziwe kude nezindawo zasemadolobheni nezasemaphandleni.Inqubo ye-Dacromet idale insimu entsha yokuvikela ukugqwala kwensimbi.Ngenxa yokuthi ukwelashwa kwe-Dacromet kuyinkqubo evaliwe, izinto eziguquguqukayo phakathi nenqubo yokubhaka ngokuyinhloko zingamanzi, aziqukethe ezinye izinto eziyingozi ezilawulwayo, futhi azinakho ukungcoliswa kwemvelo.
