Soo bandhig

Birta Corten, sidoo kale loo yaqaan birta cimilada,korten steel waa isku-darka birta dahabka ah ee soo saari kara muuqaal deggan oo miridhku u eg haddii cimiladu soo gaarto. Muuqaalkan miridhku cidhiidhiga ah ayaa ka ilaalin doona daxalka kale ee walxaha birta cimilada.

Sababtoo ah ku darida Cu, Ni, Cr iyo walxaha kale ee alloying, qalabka birta cimilada ma aha oo kaliya inay leeyihiin iska caabin aad u fiican, laakiin sidoo kale waxay leeyihiin faa'iidooyin ductility, qaabeynta, goynta, weldability, caabbinta kulaylka, xirashada caabbinta iyo dhinacyo kale.

Tilmaamid

AHL CORTENwaxay soo saartaa xaashida, gariiradda, tuubada iyo qaybta cimilada ee alaabta birta ilaa EN, JIS iyo ASTM. Birta Ahl-corten waxay ku timaadaa cabbirro kala duwan waana doorashada ugu fiican ee raadinta qaababka casriga ah iyo kuwa rusticka ah.

Halkan waxaa ah qaar ka mid ah darajooyinka caadiga ah ee saxan birta cimiladu, iyo qaar kale oo lagu yaqaan caabbinta daxalka oo tayo sare leh iyo muuqaal wanaagsan ka dib daxalka. Sida Qaaxada 1979 ee 09CUPcrni-a.

Adeegyada: daawaynta hore ee miridhku, foorarsiga, goynta, alxanka, riixida, feeray, naqshadeynta dalabka.

Waa maxay sababta loo isticmaalo birta corten?
1. Birta cimilada oo leh caabbinta daxalka xooggan ayaa aad ugu habboon deegaanka dibadda;

2. Birta cimiladu ma laha kharash dayactir ah, nolol adeeg oo dheer iyo 100% dib loo warshadayn karo;

3. Lakabka miridhku bunni ee guduudan ayaa ka dhigaya muuqaalka gaarka ah ee birta cimilada si fiican ugu dhex milmay booska.
