Da'da-adkeynta birta bir-qaadka birta
Sharraxaadda Gaaban:
Da'da adag, oo sidoo kale loo yaqaan adkaynta roobka, waa hanaan kulayl kuleyl ah oo hagaajinaya xoogga iyo adkeynta alloy-yada qaarkood, oo ay ku jiraan steel-ka-adag. xoojiya maaddada.
Da'da-adag ee birta bir-qaadka birta ah ee baarka:
Dembiyada ayaa ah qaybo bir ah oo u muuqda hannaanka dhaxalka, halkaas oo aaladda la kululeeyo ka dibna lagu dhajiyo ama lagu dhajiyo caabbinta birta ee la doonayo. , saliida iyo gaaska, iyo inbadan oo caloosha u qaabeeysan yihiin nooc bir ah oo bir ah oo caadiyan leh qaab dheer, oo si la mid ah ayaa loo adeegsadaa codsiyada meesha joogtada ah, dhererka tooska ah. ayaa loo baahan yahay, sida dhismaha dhismayaasha ama sida ashyaa'da ceeriin loogu talagalay howsha dheeriga ah.

Waa maxay mucjidada roobka ee xargaha saliidaha ah?
Roobab adag oo jilicsan oo bir ah, oo inta badan loo yaqaan 'ph bir bir aan lahayn, "waa nooc bir bir ah oo aan caadi ahayn oo marayo hannaan loo yaqaan' roog '. Hawshani waxay kor u qaadaa astaamaha farsamada ee maaddada, gaar ahaan xooggiisa iyo adag. Xadhiga ugu badan ee roobka ee ugu adag ee bir bir aan caadi ahayn waa17-4 ph(ASTM A705 Fasalka 630), laakiin fasalada kale, sida 15-5 pH iyo 13-5 ph, oo ay sidoo kale ku dhacaan qaybtaan oo ah walxaha sida chromium-ka, nikkel, naxaas, iyo mararka qaar aluminium. Intaa waxaa ku daraya arrimood ee albaabada ah waxay sare u qaadeysaa sameynta samaynta roobabku inta lagu gudajiro nidaamka daaweynta kuleylka.
Sidee loo cadaydo roobab bir ah oo bir ah?
Da'da adag ee xargaha saqafka daran waxay ku lug leedahay hanaan saddex tallaabo ah. Markii hore, maaddada waxaa lagu sameeyaa xal xalka heerkulka heerkulka ah, halkaas oo atomyada qurbaha lagu mideeyo, sameynta xalka hal-wejiga. Tani waxay keenaysaa sameynta nucleic iyo "aagag" oo birta ku yaal. Intaa ka dib, qaboojinta degdegga ah waxay dhacdaa xadka xadka jilicsan, oo abuuraya xalka adag ee adag ee loo yaqaan 'stor adag' ee dowlad-ku-meel-gaar ah. Tallaabada ugu dambaysa, xalka ugu dambeeya, xalka sare ee loo yaqaan 'inter finalatedated step step', xalka sare ee lagu dhejiyo heerkulka dhexe, roobka. Qoraalka ayaa markaa lagu hayaa gobolkaan ilaa ay ka dhacdo adkaansho. Xaddidaynta da'da ee guuleysata waxay u baahan tahay halabuurka alkolada inuu ku dhexjiro xadka xarkaha, hubinta waxtarka hawsha.
Waa maxay noocyada birta roobabku u adkaadeen?
Sheles-ka-hakinta roobka ayaa ku yimaada noocyo kala duwan, oo kasta oo loogu talagalay inuu buuxiyo wax qabad gaar ah iyo shuruudaha dalabka. Noocyo caan ah waxaa ka mid ah 17-4 ph, 15-4 ph, 13-8 ph, 17-7 ph, a-286, caadada 450, caado ahaan 630 (17-4 phMod), iyo caado nijaarka 455. Steelloni waxay bixiyaan isku darka xoog sare, iska caabbinta sare, iyo adkeyn, oo ka dhigaya ku habboon aerospace, gawaarida, baabuurta, iyo kiimikada, iyo kiimikada. Xulashada birta adkeynta roobka ayaa kuxiran qodobbada sida jawiga arjiga, waxqabadka maaddada, iyo faahfaahinta wax soo saarka.
