Weathering hlau, lub npe tag nrho ntawm cov uas yog "atmospheric corrosion resistant steel", tshwj xeeb yog tsim nyog rau kev tsim cov qauv txheej txheem hauv ib puag ncig hnyav. Piv nrog dog dig steel, cov hlau huab cua muaj qhov tseem ceeb sib txawv hauv kev tsim cov qauv, cov yam ntxwv ua tau zoo thiab daim ntawv thov kev ua haujlwm.
1. Kev sib txawv
Zoo tib yam hlau:
Mas muaj cov hlau thiab carbon, ib qho me me ntawm manganese, silicon thiab lwm cov ntsiab lus yuav raug ntxiv los txhim kho kev ua haujlwm lossis cov khoom siv neeg. Muaj tsawg dua alloy cov ntsiab lus thiab tsis muaj corrosion tshwj xeeb tsis kam.
Weathering Hlau:
Ntxiv qhov tsim nyog ntawm tooj liab (Cu), phosphorus (p), chromium (CR), npib tsib) thiab lwm yam alternal cov hlau. Cov alloy cov ntsiab lus txhim kho lub peev xwm los tiv thaiv corrosion los ntawm cov tshuaj lom neeg nyob rau hauv lub ntuj ib puag ncig los ntawm kev tsim ntawm cov yeeb yaj kiab dense ntawm cov duab.
2. Qhov sib txawv hauv cov ntawv thov teb
Zoo tib yam hlau:Dav siv rau cov laj thawj dav dav hauv cov vaj loog xws li cov tuam tsev, txuas hniav, thiab tsheb.
Weathering Hlau:Vim nws cov kev ua haujlwm zoo heev thiab kev saib xyuas me me, nws yog qhov tsim nyog rau kev siv hauv cov tsheb ciav hlau, cov tsheb ciav hlau, thiab qhib-huab cua vaj.
