Galvanized kav yuav categorized rau hauv kub-dip galvanized steel kav thiab txias-galvanized steel kav, nrog rau tom kawg maj mam phased tawm.
Kub-dip Galvanized Steel Pipes
Kub-dip galvanizing yuav reacting molten hlau nrog ib tug hlau matrix los tsim ib tug alloy txheej, li no integrating lub matrix thiab txheej. Cov txheej txheem tsim cov kav dej kub-dip galvanized pib nrog pickling cov kav hlau kom tshem tawm cov hlau oxide ntawm lawv qhov chaw. Tom qab pickling, cov kav dej raug ntxuav hauv lub tank dej uas muaj ammonium chloride, zinc chloride, los yog sib tov ntawm ob qho tib si, thiab tom qab ntawd muab tso rau hauv lub tank kub-dip galvanizing.
Cov kav dej kub-dip galvanized steel kav ua rau lub cev thiab tshuaj lom neeg cov tshuaj tiv thaiv ntawm cov hlau matrix thiab cov tshuaj molten galvanizing, tsim cov corrosion-resistant, nruj txheej txheej zinc-hlau alloy txheej. Cov txheej txheej hlau no sib txuas ua ke nrog cov zinc txheej ntshiab thiab cov hlau matrix, muab cov kav dej nrog qhov zoo xws li txheej txheej, muaj zog adhesion, thiab kev pab lub neej ntev.
Cold-Galvanized Steel Pipes
Txias galvanizing, tseem hu ua electro-galvanizing, ua rau qhov tsawg kawg nkaus galvanizing tus nqi ntawm tsuas yog 10-50g / m2, ho inferior nyob rau hauv corrosion kuj rau kub-dip galvanized kav. Txhawm rau kom ntseeg tau tias qhov zoo, feem ntau lub npe nrov galvanized yeeb nkab manufacturers tsis txhob siv electro-galvanizing (txias galvanizing). Tsuas yog cov tuam txhab me me nrog cov cuab yeej siv tsis tu ncua txais cov qauv no, feem ntau muab cov kav dej ntawm tus nqi qis dua. Lub zinc txheej ntawm txias-galvanized steel kav yog nws tus kheej txheej ntawm cov hlau matrix. Vim nws cov thinness, zinc txheej tsuas yog ua raws li cov hlau matrix thiab nws yooj yim rau tev tawm, ua rau tsis zoo corrosion kuj. Yog li ntawd, cov kav dej txias-galvanized steel tau raug txwv tsis pub siv los ua cov kav dej thiab cov kav dej hauv cov chaw nyob tshiab.
Cov txheej txheem ntau lawm ntawm Galvanized kav
Cov txheej txheem tsim khoom tshwj xeeb ntawm galvanized steel kav yog tsis pub lwm tus paub ntawm cov tuam ntxhab. Txawm li cas los xij, ib qho kev qhia dav dav tuaj yeem muab tau: a. Round steel npaj; b. Cua sov; c. Kub-dov thiab tho; d. Txiav lub taub hau; e. Pickling; f. Sib tsoo; g. Lubricating; h. Txias dov; i. Degreasing; j. Kev kho cua sov; k. Ncaj nraim; l. Txiav cov kav dej; m. Re-pickling; n. Kev soj ntsuam zaum kawg.
