Kev txias dov puas tuaj yeem txhim kho corrosion kuj ntawm SPA-H weathering steel phaj?

 

Txias dov tsis tuaj yeem txhim kho qhovinherent atmospheric corrosion kujntawm SPA-H weathering steel phaj. Qhov kev ua haujlwm tseem ceeb no yog txiav txim siab los ntawm cov hlau ruaj khov Cu / Cr / P alloy muaj pes tsawg leeg thiab corrosion- tiv taus nag lossis daus, thaum txias dov tsuas yog chav tsev - qhov kub ntawm lub cev deformation txheej txheem uas tsis hloov cov tshuaj muaj pes tsawg leeg los yog patina - tsim cov txheej txheem ntawm cov hlau.

 

Txias dov tshem tawm cov nplai zeb ntxhib thiab oxide txheej ntawm qhov kub - dov SPA-H nto, tsim kom du, tsis xws luag -dawb nto. Qhov no optimizes lubuniformity ntawm thawj patina tsimnyob rau hauv thaum ntxov theem ntawm sab nraum zoov raug, tsis txhob localized uneven oxidation tshwm sim los ntawm nto defects, thiab xyuas kom meej cov kev tiv thaiv patina hlob tsis tu ncua nyob rau hauv tag nrho cov phaj nto.

 

Txawm nrog tus nto du los ntawm txias dov, lubntev -lub sij hawm atmospheric corrosion tus nqintawm txias-rolled SPA-H (0.01–0.03 mm/xyoo) thiab qhov ceev, ruaj khov, thiab kev tiv thaiv kev ua tau zoo ntawm cov tsim patina yog tag nrho raws li kub-rolled SPA-H, tsis muaj kev txhim kho tseem ceeb los tiv thaiv- cuam tshuam corrosion.

 

Txias dov tsis tuaj yeem nthuav dav qhov cuam tshuam rau thaj tsam ntawm SPA-H. Txias-rolled SPA-H tseem muaj cov tsis zoo corrosion kuj nyob rau hauv hnyav marine / ntsev- tsuag, siab-kub humid, thiab acid/alkali corrosive ib puag ncig, tib yam li kub- dov SPA-H.
