SPA-H weathering zitsulo dzenje gawo, Corden Zitsulo mbale
1. Kufotokozera kosavuta:
SPA-Hnyengo yachitsulo, yomwe imadziwikanso kuti atmospheric corrosion-resistant steel, imatanthauza mtundu wa low-aloyichitsulo champhamvu kwambiri
okhala ndi zinthu zochepa za alloying, mtengo wotsika, komanso kukana bwino kwa dzimbiri mumlengalenga. The chachikulu alloying
zinthu ndi Cu, P, Cr, Ni, Si, Mn, V, RE, etc. Pa ntchito weathering zitsulo, wandiweyani ndi zolimba Ufumuyo zoteteza filimu.
Zopangira dzimbiri zimapangika pang'onopang'ono pamtunda kuti ziteteze mpweya, madzi ndi zinthu zina zowononga mumlengalenga
kupitilira kuwononga gawo lapansi, kotero kuti kuchuluka kwa dzimbiri kumachepetsedwa kwambiri poyerekeza ndi chitsulo cha carbon. . Chifukwa cha mphamvu zake zazikulu ndi
mtengo wololera, mtengo wopanga ndi wotsika kwambiri kuposa chitsulo chosapanga dzimbiri. SPA-H wamkulu muyezo ndi: JISG3125-2015.

4. Kugwiritsa ntchito:
1) SPA-H ndi chitsulo chanyengo chopangira chidebe, kudula ndi kuwotcherera. SPA-H imagwiritsidwa ntchito makamaka pazotengera zazombo,
milatho yachitsulo, zombo ndi akasinja kuti mupewe dzimbiri mumlengalenga.
2) Chitsulo cha SPA-H chimagwiritsidwa ntchito kwambiri popanga zotengera. Makampani opanga zotengera ali ndi mbiri yoposa
Zaka 50 padziko lapansi. Zaka 30 zapitazo, zotengera za dziko langa zinalibe kanthu. Kuyambira kukonzanso ndi kutsegula, dziko langa
ntchito yomanga madoko komanso mayendedwe otengera zinthu zapitilira kukula. Makamaka m'zaka zaposachedwa, mayiko akukumana nawo
mkhalidwe wa “chotengera chimodzi ndi chovuta kuchipeza.
5. Mfundo yolimbana ndi dzimbiri:
Chitsulo chikakumana ndi kuwala kwa dzuwa ndi mphepo, kukana kwa dzimbiri ndikofunikira kwambiri. Pambuyo powonjezera phosphorous, mkuwa, chromium,
nickel ndi zinthu zina zowunikira zitsulo, filimu yowuma komanso yolimba yoteteza idzapangidwa pamwamba pa zinthu zamkuwa, zomwe
amatha kugwira ntchito inayake yoteteza.
