Yintoni ekufuneka ihlawulwe ngaphambi kokuba i-galvanizing wire?

Ucingo olufakwe igalvanizedyenziwe ngomgangatho ophantsi wekhabhoni yentsimbi yocingo intonga, eshushu ifakwe igalvanized emva kokuzoba, ukuchola, ukususwa komhlwa, ubushushu obuphezulu be-annealing.Icutshungulwa ngokupholisa kunye nezinye iinkqubo zobuchwepheshe.Ucingo oluyigalvanized lwahlulwe lwaba lucingo olushushu lwegalvanized kunye negalvanized wire.I-galvanized iron wire inokuqina okulungileyo kunye nokuqina, kwaye umxholo ophezulu we-zinc unokufikelela kwi-300g / m2.Ineempawu zokugquma kwe-zinc engqindilili kunye nokumelana nomhlwa okuqinileyo.

Yintoni ekufuneka iqwalaselwe phambi kokuba i-galvanizing iucingo lwezinki?
Xa kuthelekiswa nezinye iinkqubo ze-galvanizing, iimfuno zokucoca ucingo lwensimbi ephantsi kwekhabhoni phambi kokuba i-galvanizing iphantsi.Nangona kunjalo, kwimeko yangoku yokufuna rhoqo ukuphucula umgangatho we-zinc coating, ezinye izinto ezincinci ezingcolisayo eziziswe kwindawo yokuhlambela ngokucacileyo ziye zaba yingozi.Ngenxa yokuba ukucoca i-coating ye-zinc kuchitha ixesha elininzi kunye nokunciphisa imveliso, kubaluleke kakhulu ukucoca ngokufanelekileyo i-substrate kwaye uyihlambulule ngokufanelekileyo phambi kwe-electroplating.
Iziphene ezinjengomaleko wemaski yobuso kunye nokufakwa komphezulu kunokufunyanwa kwaye kuphathwe ngetheknoloji eqhelekileyo ukusuka kumphezulu wangaphandle womaleko obekiweyo wocingo olwenziwe ngamazimba phambi kokugalela;Ugwebu olugqithisileyo lwenziwa ngokuzisa isepha kunye ne-saponifiable fat surfactant ebhafini.Izinga eliphakathi lokubunjwa kwegwebu lisenokungabi nabungozi.Inani elikhulu lamancinci amancinci amancinci kwi-tank liquid linokuzinzisa umaleko we-foam.Kusebenza ngokufanelekileyo ukususa izinto ezisebenzayo eziphezu komhlaba ngokwenza i-mat ngekhabhoni esebenzayo okanye ukwenza i-foam ingazinzi ngokuhluza;Amanye amanyathelo nawo kufuneka athathwe ukunciphisa ukuqaliswa kwe-surfactant.Ukuqaliswa kwezinto eziphilayo kunokunciphisa kakhulu isantya se-electroplating.Nangona ifomyula yeekhemikhali ifanelekile kwizinga eliphezulu lokubeka, ubukhulu bokwambathisa abukwazi ukuhlangabezana neemfuno emva kokuba izinto eziphilayo zingeniswa, ngoko ke ikhabhoni esebenzayo ingasetyenziselwa ukunyanga isisombululo sokuhlambela.
