SPA-H weathering simbi hollow chikamu, Corden Steel ndiro
1. Tsanangudzo iri nyore:
SPA-Hweathering simbi, inozivikanwawo seatmospheric corrosion-resistant steel, inoreva rudzi rwepasi-.alloysimbi yakakwirira-yakasimba
ine hushoma hwezvinhu zvinosanganiswa, mutengo wakaderera, uye yakanaka inodzivirira ngura mumhepo. The main alloying
zvinhu zviri Cu, P, Cr, Ni, Si, Mn, V, RE, etc. Panguva yekushandiswa kwesimbi yemamiriro ekunze, firimu rinodzivirira uye rakasimba rakanyatsobatanidzwa.
corrosion zvigadzirwa zvichaumbwa zvishoma nezvishoma pamusoro kudzivirira okisijeni, mvura uye imwe corrosion media mumhepo kubva
kuwedzera corroding substrate, kuitira kuti chiyero chekuora chideredze zvakanyanya kana chichienzaniswa nekabhoni simbi. . Nekuda kwesimba rayo rakakwirira uye
mutengo unonzwisisika, mutengo wekugadzira wakaderera zvakanyanya pane simbi isina tsvina. SPA-H yepamusoro chiyero ndeye: JISG3125-2015.

4. Application:
1) SPA-H isimbi yemamiriro ekunze yekugadzira midziyo, kucheka uye kupinza. SPA-H inonyanya kushandiswa kumidziyo yengarava,
mabhiriji esimbi, zvikepe uye matangi kudzivirira ngura yemuchadenga.
2) SPA-H weathering simbi inonyanya kushandiswa kugadzira midziyo. Indasitiri yekutakura midziyo ine nhoroondo inodarika
50 makore munyika. Makore makumi matatu apfuura, kutakura kwemidziyo yenyika yangu kwakanga kuchiri kusina. Kubva pakuvandudzwa nekuvhurwa, nyika yangu
kuvakwa kwechiteshi uye kutakura kwemidziyo zvakaramba zvichikura. Kunyanya mumakore achangopfuura, nzanga yepasi rose yakatarisana
mamiriro e“mudziyo mumwe wakaoma kuwana.
5. Corrosion resistance principle:
Kana simbi ichiiswa kuchiedza chezuva nemhepo, kusaonda kwayo kunonyanya kukosha. Mushure mekuwedzera phosphorus, mhangura, chromium,
nickel uye zvimwe zvinoteedzera zvinhu kune simbi, dense uye yakasimba inodzivirira firimu ichaumbwa pamusoro pezvinhu zvemhangura, izvo.
inogona kutamba imwe basa rekudzivirira.
