Lub hom phiaj ntawm txias galvanizing thiab kub galvanizing ntawmhnub ci teeb ncejyog los tiv thaiv corrosion thiab ncua lub neej kev pab cuam ntawm lub hnub ci txoj kev teeb, yog li dab tsi yog qhov txawv ntawm ob?
1. Kev tshwm sim
Cov tsos ntawm txias galvanizing yog du thiab ci. Cov txheej txheem electroplating nrog cov txheej txheem xim passivation feem ntau yog daj thiab ntsuab, nrog xya xim. Cov txheej txheem electroplating nrog cov txheej txheem dawb passivation yog xim dawb, thiab xim me ntsis hauv ib lub kaum ntse ntse ntawm lub hnub ci. Nws yog ib qho yooj yim los tsim "hluav taws xob hlawv" ntawm cov ces kaum thiab cov npoo ntawm cov pas nrig complex, uas ua rau cov zinc txheej ntawm qhov no thicker. Nws yog ib qho yooj yim los tsim tam sim no ntawm lub ces kaum sab hauv thiab tsim nyob rau hauv-tam sim no grey cheeb tsam, uas ua rau cov zinc txheej nyob rau hauv cov cheeb tsam no nyias. Cov pas nrig yuav tsum tsis muaj zinc pob thiab agglomeration.
Cov tsos ntawm kub galvanizing yog me ntsis rougher tshaj qhov txias galvanizing, thiab nws yog silvery dawb. Cov tsos mob yog yooj yim los tsim cov txheej txheem dej cim thiab ob peb tee, tshwj xeeb tshaj yog nyob rau ntawm ib kawg ntawm tus pas nrig.
Zinc txheej ntawm me ntsis ntxhib kub galvanizing yog kaum ob lub sij hawm thicker dua txias galvanizing, thiab nws cov corrosion kuj yog kaum ob lub sij hawm ntawm cov hluav taws xob galvanizing, thiab nws cov nqi yog ib txwm siab dua li ntawm txias galvanizing. Txawm li cas los xij, nyob rau lub sijhawm ntev, kub galvanizing nrog kev tiv thaiv xeb rau ntau tshaj 10 xyoo yuav nrov dua li txias galvanizing nrog kev tiv thaiv xeb tsuas yog 1-2 xyoos.
2. Txheej txheem
Txias galvanizing, tseem hu ua galvanization, yog siv cov khoom siv electrolytic los muab cov pas nrig rau hauv cov tshuaj uas muaj zinc ntsev tom qab degreasing thiab pickling, thiab txuas cov ncej tsis zoo ntawm cov khoom siv electrolytic. Muab ib lub phaj zinc rau ntawm tus pas nrig sab nraud kom txuas mus rau tus ncej zoo ntawm cov khoom siv electrolytic, txuas cov khoom siv hluav taws xob, thiab siv cov kev taw qhia ntawm qhov tam sim no los ntawm tus ncej zoo mus rau tus ncej tsis zoo kom tso ib txheej zinc. ntawm lub workpiece; Kub galvanizing yog tshem tawm cov roj, kua qaub ntxuav, dip tshuaj thiab qhuav lub workpiece, thiab ces muab tso rau hauv lub molten zinc tov rau ib lub sij hawm, thiab ces muab rho tawm.
3. Txheej txheej
Muaj ib txheej ntawm nkig compound ntawm txheej thiab substrate ntawm kub galvanizing, tab sis qhov no tsis muaj kev cuam tshuam zoo rau nws cov corrosion kuj, vim hais tias nws txheej yog ntshiab zinc txheej, thiab cov txheej yog sib xws, tsis muaj pores, thiab tsis yog. yooj yim rau corroded; Txawm li cas los xij, txheej txheej ntawm galvanizing txias yog tsim los ntawm qee cov zinc atoms, uas belongs rau lub cev adhesion. Muaj ntau qhov pores ntawm qhov chaw, thiab nws yooj yim rau kev cuam tshuam los ntawm ib puag ncig thiab corroded.
4. Qhov sib txawv ntawm ob
Los ntawm ob lub npe, peb yuav tsum paub qhov txawv. Zinc nyob rau hauv txias galvanized steel kav yog tau nyob rau hauv chav tsev kub, thaum zinc nyob rau hauv kub galvanizing yog tau ntawm 450 ℃ ~ 480 ℃.
5. Txheej thickness
Lub thickness ntawm txias galvanizing txheej yog feem ntau tsuas yog 3 ~ 5 μ m. Nws yog yooj yim dua rau txheej txheem, tab sis nws cov corrosion kuj tsis zoo heev; Cov txheej kub-dip galvanized feem ntau muaj 10 μ Qhov kev tiv thaiv corrosion ntawm cov tuab ntawm m thiab saum toj no zoo dua, uas yog kwv yees li kaum ob lub sij hawm ntawm qhov txias-galvanized teeb ncej.
6. Nqe sib txawv
Kub galvanizing yog qhov teeb meem ntau dua thiab xav tau hauv kev tsim khoom, yog li qee lub tuam txhab nrog cov cuab yeej qub thiab cov nplai me feem ntau txais yuav txias galvanizing hom hauv kev tsim khoom, uas yog qis dua ntawm tus nqi thiab tus nqi; Txawm li cas los xij,Kub-dip galvanizing manufacturersfeem ntau yog tsim thiab loj hauv nplai. Lawv muaj kev tswj hwm zoo dua qub thiab tus nqi siab dua.
Qhov sib txawv saum toj no ntawm kub galvanizing thiab txias galvanizing ntawm hnub ci txoj kev teeb ncej yog sib koom ntawm no. Yog hais tias lub hnub ci txoj kev teeb ncej yuav tsum tau siv nyob rau hauv cov ntug dej hiav txwv, lawv yuav tsum xav txog cov cua tsis kam thiab corrosion kuj, thiab tsis txhob tsim ib tug khib nyiab project vim yog ib ntus greed.
