Tshaj tawm rau 04-04-2018Dacromet thev naus laus zis yuav siv rau hauv cov txheej txheem ntawm kev tsim khoom thiab kev ua haujlwm.Nrog rau kev sib txuas ntxiv ntawm kev siv thev naus laus zis, Dacromet thev naus laus zis tau dhau los ua haujlwm tau zoo, uas nws daim ntawv thov tau lees paub los ntawm txhua tus.Cia peb qhia rau koj txog kev siv Dacromet ua tshuab.1.Qhov muaj peev xwm corrosion ntawm dacromet txheej thiab cov txheej txheem sib xyaw hauv dej hiav txwv yog qhov tsis zoo nyob rau theem pib, thiab qhov corrosion ntawm cov khoom txheej feem ntau tshwm sim.Hauv particular, cov txheej txheem kev hloov kho saum npoo ntawm cov txheej txheem sib xyaw ua lub luag haujlwm zoo dua hauv kev thaiv cov dej hiav txwv nkag mus rau sab hauv ntawm txheej txheej.
2. Nrog rau kev tsim cov khoom ruaj khov corrosion khoom zaj duab xis txheej rau ntawm qhov chaw tsis muaj chromium-dacromet txheej, corrosion ntawm txheej yog maj mam suppressed kom ncav cuag lub peev xwm ruaj khov, thiab qhov ruaj khov muaj peev xwm ntawm ob yog -0.643 V thiab - 0 ,632v.3.Qhov sib txawv ntawm qhov muaj peev xwm corrosion ntawm peb qhov qhia tau hais tias cov zincizing txheej muaj cov nyhuv muaj zog ntawm kev txi anode ntawm lub hauv paus hlau.Nyob rau hauv cov dej hiav txwv, cov zincizing txheej yuav sai sai thiab cov nyhuv tiv thaiv ntawm txheej ntawm substrate yuav raug txo.4.Dacromet thev naus laus zis yog ib qho kev sib xyaw ua ke thev naus laus zis.Qhia txog cov thev naus laus zis no, Tuam Tshoj tsis tau qhia txog lub ntsej muag sab saum toj Dacromet txheej tshuab uas tau sib tw tib lub sijhawm.Nws pom tias muaj kev tiv thaiv corrosion ntawm cov impedance spectrum thiab tau ruaj khov.Lub vojvoog ntawm ob lub capacitive arcs loj, thiab cov kab tuaj yeem pom kwv yees li, qhia cov yam ntxwv ntawm impedance.Lub sijhawm no, cov tshuaj tiv thaiv corrosion hloov pauv.
