Tshaj tawm rau 29-04-2019Dacromet's thev naus laus zis muaj cov txiaj ntsig zoo uas cov tsoos plating tsis tuaj yeem sib tw, thiab nws nrawm nrawm rau kev lag luam thoob ntiaj teb.Tom qab ntau tshaj 20 xyoo ntawm kev txhim kho thiab kev txhim kho tas mus li, Dacromet thev naus laus zis tau tam sim no tsim cov txheej txheem kho kom tiav, uas yog siv dav hauv kev kho cov khoom siv hlau.
Cov yam ntxwv tseem ceeb ntawm chrome-dawb ntsuab txheej
Thickness: 1. Lub thickness ntawm cov txheej yog 6-12 microns, thiab lub thickness ntawm cov txheej nrog cov txheej txheej yog 10-15 microns.2, anaerobic brittle: txheej txheej tsis xav tau pickling lossis plating.3. Kev tshem tawm ntawm kev hem thawj ntawm ob chav hlau corrosion: Lead tshem tawm cov bimetallic corrosion ntawm zinc-aluminium lossis zinc-hlau uas feem ntau tshwm sim hauv zinc txheej.4. Solvent resistance: Cov txheej txheem inorganic muaj cov kuab tshuaj zoo heev.5, tshav kub tsis kam: cov txheej muaj ntau cov ntawv hlau, uas tuaj yeem ua hluav taws xob.6, corrosion resistance Performance: ntsev tsuag tshuaj ntsuam 240-1200 teev 8, adhesion kev ua tau zoo: zoo dua zinc chromium txheej (Dacro txheej).
Kev ua tau zoo ib puag ncig: 1, tsis muaj chromium: tsis muaj cov chromium (xws li trivalent thiab hexavalent) 2, tsis muaj cov tshuaj lom: tsis muaj nickel, cadmium, lead, antimony thiab mercury.
Chrome-dawb ntsuab txheej los tiv thaiv corrosion txoj kev
Cov nyhuv shielding: 1. Cov scaly zinc-aluminium hmoov zoo heev txhim kho kev nkag mus ntawm corrosive media.2, yin thiab yang kev tiv thaiv: zinc li anode txi los tiv thaiv cov hlau los ntawm corrosion.3. Passivation: Hlau oxides qeeb lub bimetallic corrosion ntawm zinc thiab hlau substrates.4, kho tus kheej: cov pa thiab carbon dioxide nyob rau hauv cov huab cua react nrog zinc nyob rau saum npoo ntawm txheej los tsim zinc oxide thiab zinc carbonate.Txij li thaum lub ntim ntawm zinc oxide thiab zinc carbonate yog loj dua tib cov nyiaj zinc, thaum nws tsiv mus rau qhov chaw puas lawm, nws tuaj yeem ua rau cov nyhuv kho.
