Corten qib a?
Corten qib A, tseem raug xa mus rau hauv Astm A242 hom 1 thiab feem ntau yog pawg neeg siv hluav taws xob, yog qhov siab {}} allo illionance rau nws cov kev tiv thaiv zoo rau cov atmospheric corrosion.
Thaum raug rau sab nraum zoov tej xwm txheej, corten ib daim ntawv ruaj khov, tiv thaiv cov yeeb yaj kiab oxide - feem ntau hu ua alub moo plaubCov. Qhov no patina tshwm sim li ib tug xeb {{1} Zoo li saum npoo tab sis ua haujlwm raws li kev thaiv npog, tiv thaiv ntxiv corrosion los ntawm cov khoom.
Vim tias qhov no tus kheej - Tiv thaiv cov yam ntxwv, Corten A
Nws muaj peev xwm tiv thaiv noo noo, kev ua qias tuaj, sib txawv ntawm huab cua txias, thiab huab cua kev kho huab cua ua haujlwm qis dua nws txoj kev ua haujlwm lub neej.
Qhov kev sib xyaw ua ke ntawm cov nqi tswj kav ntev, thiab visually striking tsos ua rau corten nrov hauv ob qho chaw thiab kev ua kom zoo nkauj.
