Birta aan daxalka lahayni waa ka badan tahay birta u adkaysata daxalka.Birta aan la taaban karin waxaa badanaa loo doortaa walxo badan oo loogu talagalay codsiyo badan sababtoo ah xooggeeda, caabbinta daxalka iyo awoodda la qabsiga xaaladaha gaarka ah.
304 304L 316 316L Alaab-qeybiyeyaal saxan bir ah oo Shiinaha
Birta aan daahin 304 waa heerka ugu isticmaalka badan ee birta ah.Waa bir aan lahayn chromium-nickel austenitic oo leh kaarboon yar oo xoogaa ka sarreeya chromium iyo nikkel marka loo eego nooca AISI 301 iyo 302. Fasalka 304 aad buu u dhuuban yahay marka uu jiro xaalad la daboolay.Waxay leedahay sifooyin heerkul sare oo wanaagsan iyo sidoo kale adayg wanaagsan heerkulka hooseeya.Waxay si fiican ugu habboon tahay alxanka iyo halka alaabta la dhammeeyey ay tahay inay iska caabiyaan noocyada daxalka ee aadka u daran.

Tani ma khusayso oo keliya noocyada kala duwan ee kiimikaad ee ka samaysan birta aan birta lahayn, laakiin sidoo kale dahaarka kala duwan iyo daawaynta dusha sare ee la marsado iyadoo ku xidhan dhamaadka loogu talagalay isticmaalka alaabta.
Fasalka 2B waa mid ka mid ah daawaynta dusha sare ee inta badan la isticmaalo ee warshadaha birta ah.Waa qayb-milicsi, siman oo lebbisan, in kastoo aanay ahayn muraayad.Diyaarinta dusha sare waa tallaabada ugu dambeysa ee habka: xaashida birta ayaa marka hore la sameeyay iyadoo la riixayo inta u dhexeysa duubabka meesha foornada.Ka dib waa la jilciyaa iyadoo la tirtirayo ka dibna dib ayaa loo gudbiyaa iyada oo loo marayo duubo.
Si meesha looga saaro wasakhowga dusha sare, dusha sare waa mid aashito ah oo u dhexaysa polishing rollers dhowr jeer si loo gaaro dhumucda la rabo.Waxay ahayd baaskii ugu dambeeyay ee horseeday dhammaystirka 2B.
2B waa dhamaystirka caadiga ah ee buundooyinka birta ah ee caadiga ah, oo ay ku jiraan 201, 304, 304 L, iyo 316 L. Caannimada 2B polishing, marka lagu daro dhaqaale ahaan iyo adkaysi badan oo daxalka, waxay ku jirtaa fududaynta in lagu nadiifiyo giraangiraha maro iyo xarun.
Caadi ahaan, birta dhammayn ee 2B waxaa loo isticmaalaa habaynta cuntada, qalabka wax lagu dubto, weelasha, haamaha kaydinta, iyo qalabka dawooyinka oo buuxiya heerarka USDA ee warshadahan.
Habkani maaha mid la aqbali karo marka badeecada ugu dambeysa ay tahay xalka la isku duro ama otic.Tani waa sababta oo ah dulduleelo ama jeebab ayaa ku samaysan kara oogada birta ah.Banaanadahani waxay ku dabin karaan wasakhda ka hoosaysa dusha sare ama birta.Ugu dambeyntii, walxahan ajnabiga ah way baxsan karaan oo sumayn karaan alaabta.Electropolishing dusha sare ayaa ah habka ugu habboon ee lagu taliyay ee hagaajinta simanaanta dusha sare ee codsiyadan.
Electropolishing waxay u shaqeysaa iyadoo la isticmaalayo kiimikooyin iyo koronto si ay u nadiifiso meelaha sare ee dusha birta ah.Xataa iyada oo warshad lagu dabaqay Dahaarka Smooth 2B, dusha sare ee birta aan lahayni uma muuqan doonto mid siman marka la weyneeyo.
Celceliska qallafsanaanta (Ra) waxa loo isticmaalaa in lagu tilmaamo simannaanta birta oogada, waana isbarbardhigga celceliska faraqa u dhexeeya dhibcaha hoose iyo kuwa sare ee dusha sare muddo ka dib.
Caadi ahaan, warshada birta cusub ee ahama ee leh dhamaystirka 2B waxay leedahay qiime Ra inta u dhaxaysa 0.3 micron (0.0003 mm) ilaa 1 micron (0.001 mm) iyadoo ku xidhan dhumucdiisu ( dhumucdiisuna tahay).Dusha sare ee Ra waxaa lagu dhimi karaa 4-32 micro-inji iyadoo la isticmaalayo korantada saxda ah, iyadoo ku xiran sifooyinka birta.
Dhammaadka fasalka 2B waxaa lagu gaaraa in lagu cadaadiyo walxaha laba rullaluistemadka.Hawl-wadeennada qaarkood waxay u baahan yihiin dayactirka jardiinka ka dib dib-u-habaynta ama hagaajinta markabka ama qalabka kale.
Inkasta oo dhamaystirka dusha sare ee laga helo makaanikada ama korantada aan si sahlan loo soo saari karin, waxay noqon kartaa mid aad u dhow, gaar ahaan marka la eego qiyamka Ra.Natiijadu tahay daawaynta saxda ah ee korantada, xitaa waxqabadka ka sii wanaagsan marka la eego farsamaynta walxaha ayaa la gaari karaa marka loo eego daawaynta dusha sare ee 2B ee asalka ah.
Sidaa darteed, qiyaasta 2B waxaa loo tixgelin karaa bar bilow wanaagsan.Dahaarka 2B waxay leeyihiin faa'iidooyin si fiican loo yaqaan waana kuwo dhaqaale.Waxaa lagu sii wanaajin karaa elektropolishing si loo dhammeeyo jilicsanaanta, heerarka sare iyo faa'iidooyinka muddada dheer ee kala duwan.
