Qhov kub - dip galvanizing txheej txheem ua rau cov scaffolding haum rau txhua hom chaw hnyav.
Kub - dip galvanized scaffolding yog cov khoom scaffolding yog los ntawm kev ua kom haum corrosion- kub galvanizing txheej txheem. Nws cov ntsiab lus zoo yog cov huab cua tiv thaiv thiab lub neej pabcuam ntev
Cov Txheej Txheem Kawm Tseem Ceeb
Kub - dip galvanizing, tseem hu ua kub dip galvanization, yog tus txheej txheem uas cov duab scaffolding yog raus hauv Molten zinc. Ib qho kev hnav khaub ncaws zinc -} Iron co txheej txheej rau saum npoo. Zinc txheej cais hlau los ntawm huab cua thiab ya raws. Nws tseem muab kev tiv thaiv kab mob rau kev tiv thaiv steel corrosion.
Cov txheej txheem tseem ceeb
Pretricatment
Derust, degrease thiab huv scaffolding kav, fasteners thiab lwm yam. Tshem tawm cov nplaim hluav taws thiab oxide kom paub meej zinc txheej adhesion.
Yws
Cov kab ntxuav cov khoom xyaw hauv flux, feem ntau yog kev sib xyaw ntawm zinc chloride thiab ammonium chloride. Ib cov ntaub ntawv ua yeeb yaj kiab tiv thaiv kom tsis txhob muaj oxidation theem nrab ua ntej cov khoom siv nkag mus hauv chav da zinc.
Kub - dip Galvaning
Cov khoom xyaw hauv Molten Zinc ntawm 440 - 460℃rau qee lub sijhawm. Kev tawm tsam metallurgical tshwm sim ntawm zinc thiab sib xyaw ua ke ntawm zinc-hlau txheej thiab cov txheej ntshiab zinc txheej.
Tshaj tawm -} kev kho
Txias thiab passivate Cheebtsam tom qab lawv coj tawm ntawm cov da dej zinc. Tshem tawm cov zinc coodules ntau dhau ntawm cov nplaim los txhim kho coure corrosion tsis kam thiab tsos.
Cov ntsiab lus zoo ntawm cov txheej txheem
Cov txheej muaj cov khaub ncaws tuab zoo nkauj thiab cov kev pab them tag nrho. Nws tuaj yeem qhwv cov txheej txheem ntawm scaffolding xws li sawv, cov ces kaum thiab Welds.
Cov txheej txheej zinc kom khov kho nrog cov hlau, tsis yooj yim kom poob tawm. Nws muaj kev cuam tshuam muaj zog thiab hnav tsis kam.
Nws muab cov tsis tau zoo tshaj plaws corrosion. Nws cov kev pabcuam lub neej nyob rau hauv ib puag ncig hnyav xws li thaj chaw noo nyob sab nraum zoov thiab noo noo} galaxized lossis pleev xim rau scaffolding.
