Idiphu eshushu yokugalela ipleyiti yentsimbi ikwabizwa ngokuba yi- hot dip galvanizing.I-Zinc ingots iyancibilika kwiindawo ezitshatyalaliswayo kwaye ezinye izinto ezincedisayo zongezwa kwi-galvanizing yediphu eshushu.Emva koko iinxalenye zegridi zensimbi zifakwe kwi-tank ye-galvanizing kwaye i-galvanizing layer ifakwe kwi-plate yensimbi.Amandla ediphu eshushu galvanizing kuxhomekeke ukumelana nomhlwa, kunye nokuncamathela kunye nobulukhuni sheet amazi ngcono.Ubungakanani bepleyiti yentsimbi emva kokufakwa kwegalvanizing.Ngoko ke lo ngumlinganiselo jikelele we-zinc.
Ukubunjwa kwediphu eshushu yomaleko wegalvanizing yenziwe ngumaleko wediphu otshisayo, owenziwe nge-iron zinc alloy phakathi kwentsimbi ye-matrix kunye nomgangatho ococekileyo we-zinc.Ubume be-workpiece yenziwe ngumaleko we-iron zinc alloy kwidiphu eshushu, ukuze i-iron kunye ne-zinc ecocekileyo yomaleko ichukumise.Xa i-workpiece yentsimbi intywiliselwa kwisisombululo se-zinc etyhidiweyo, i-zinc yokuqala kunye nentsimbi (umzimba) yenziwa kwi-interface.Le yikristale eyenziwe ngeeathom ze-zinc kwintsimbi yentsimbi eyomeleleyo.Xa iiathom zesinyithi ezimbini zidityanisiwe, amandla omxhuzulane phakathi kweeathom mancinane kakhulu.
Ngaloo ndlela, xa izinc yanele ekunyibilikeni okuqinileyo, ezi athom zimbini zezinc neiron ziyahlakazeka enye kwenye.Iiathom ze-zinc kwi-matrix ye-iron zifuduselwa kwi-lattice ye-matrix, kwaye izinto ze-iron zenziwe ngokuthe ngcembe zibe yi-alloys.Ukubunjwa kwe-zinc yentsimbi kunye ne-intermetallic compound FeZn13 kwisisombululo se-zinc etyhidiweyo kunye nezantsi kweshiti elitshisayo le-galvanized lingasetyenziswa njenge-zinc slag.Umaleko we-zinc ococekileyo owenziwe ngesisombululo se-zinc leaching yikristale enehexagonal.
Xa ubushushu busebenza kwiqondo lokushisa elifanayo kunye nobushushu obufanayo bugcinwe, ubungakanani bentsimbi echithweyo ayifani.Malunga nama-500, ilahleko yentsimbi iyanda kakhulu ngokongezwa kweqondo lobushushu kunye nokugquma.Iphantsi okanye iphezulu kune-480 ~ 510c, kwaye ilahleko ye-epitaxial iron ihamba kancinci, kwaye kunzima ukubamba ubude bexesha.Ke ngoko, wonke umntu uyakubiza i-480 ~ 510c indawo enyibilikayo embi.
Kulo luhlu lweqondo lokushisa, isisombululo se-zinc sigxininiswe kakhulu kwi-workpiece kunye nesitya se-zinc, kwaye isinyithi silahlekile kwi-560 degrees Celsius ukongeza ngokucacileyo, kwaye i-zinc iya kuba yi-iron substrate ngaphezu kwe-660 degrees Celsius, i-zinc slag iya kongezwa. ngokukhawuleza, i-plating ayinakusetyenziswa.Ngoko ke, i-electroplating yenziwa kuluhlu lwama-430 ~ 450 degrees Celsius.
