Soo-saare Shiinees ah oo Cimilada u adkeysanaysa Taarikada Dhismaha ee Qurxinta
(1) Bir cimiladu sareeyso
Birta qaab dhismeedka iska caabinta cimilada sare waa in lagu daro qadar yar oo naxaas ah, fosfooraska, chromium, iyo nikkel birta si ay u sameeyaan lakab ilaalin dusha sare ee biraha wadajirka ah si loo hagaajiyo waxqabadka birta ee ka hortagga daxalka atmospheric.Waxa kale oo aad ku dari kartaa qadar yar oo molybdenum ah, niobium, Cutubyada sida vanadium, titanium iyo zirconium waxay sifeyn karaan miraha, hagaajinta sifooyinka farsamada ee birta, hagaajinta xoogga iyo adkaanta birta, waxay yareeyaan heerkulka kala-guurka ee jajaban, oo waxay sameeyaan iska caabin fiican oo jab jaban.
(2) Birta cimilada ee qaab dhismeedka alxanka
Walxaha lagu daray birta, marka laga reebo fosfooraska, asal ahaan waxay la mid yihiin birta qaab dhismeedka iska caabinta cimilada sare, waxayna leeyihiin shaqo isku mid ah, waxayna hagaajiyaan waxqabadka alxanka.
Isticmaalka birta qaab dhismeedka iska caabinta cimilada sare ayaa ka wanaagsan birta iska caabinta cimilada ee qaab dhismeedka alxanka ah sababtoo ah iska caabinta daxalka atmospheric.Waxaa inta badan loo isticmaalaa dabin, jeexjeexid iyo alxanka qaybaha dhismeed ee baabuurta, weelasha, dhismayaasha, munaaradaha iyo dhismayaasha kale.Marka loo isticmaalo sida qaybaha qaabdhismeedka alxanka, dhumucda birta waa in aanay ka badnaan 16mm.Birta u adkeysata cimilada ee qaab dhismeedka alxanka ayaa leh wax qabad alxanka oo ka wanaagsan birta qaab dhismeedka u adkeysaneysa cimilada sare, waxaana inta badan loo isticmaalaa qeybaha qaab dhismeedka alxanka ee buundooyinka, dhismayaasha iyo dhismooyinka kale.
Fiiro gaar ah: waxaan bixinaa adeeg habayn, dhammaan tuubada birta waxay ku xiran tahay naqshaddaada si aad u soo saarto.
