Tayada Raqiiska ah ee ASTM siman
Faahfaahinta Alaabta
Xagasha birta oo simanbaararka waxaa inta badan loo isticmaalaa codsiyada dhismaha iyo injineernimada si ay u bixiyaan taageero qaabdhismeed iyo xoojinta.Baararkan waxaa sida caadiga ah laga sameeyaa birta kaarboonka ama birta aan la taaban karin, iyaga oo siinaya xoog sare, adkeysi, iyo iska caabin daxalka.
Erayga "isku mid" waxa uu tilmaamayaa in labada lugood ee baarka xagasha ay yihiin dherer siman oo ay sameeyaan xagal 90-degree ah.Tani waxay ka dhigeysaa mid ku habboon in loo isticmaalo qaab-dhismeedka, xargaha, taageerada, iyo qaybaha kala duwan ee qaabdhismeedka.
Xaglahaan baararka waxaa lagu soo saaraa cabbirro iyo cabbirro caadi ah, taasoo ka dhigaysa kuwo ku habboon codsiyo kala duwan.Si sahal ah ayaa loo alxan karaa, loo jari karaa, loo leexin karaa, loona farsamayn karaa si ay ugu habboonaato shuruudaha mashruuca ee gaarka ah.
Intaa waxaa dheer, baararka xagasha birta ah ee siman ayaa laga heli karaa dhumucyo kala duwan iyo ballacyo kala duwan si ay u daboolaan baahiyaha kala duwan ee qaadista iyo naqshadaha qaabdhismeedka.
Waxaa muhiim ah in la ogaado in cabbirka gaarka ah iyo faahfaahinta dulqaadku ay ku kala duwanaan karaan iyadoo lagu saleynayo heerarka gobolka ama kuwa caalamiga ah, sidaas darteed waxaa lagu talinayaa in la hubiyo qeexitaannada la xiriira darajada gaarka ah iyo nooca xagasha birta ah ee looga baahan yahay mashruucaaga.

Astaamaha
Kaarboon bir xagal siman, oo sidoo kale loo yaqaanno birta xagasha kaarboon, waxay leedahay astaamo dhowr ah oo muhiim ah oo ka dhigaya mid ku habboon codsiyada qaabdhismeedka iyo dhismaha ee kala duwan:
Xoog iyo Waarta: Birta kaarboon waxa lagu yaqaanaa awood sare iyo adkeysi, taas oo ka dhigaysa mid ku haboon bixinta taageerada qaabdhismeedka mashaariicda dhismaha.
Kala duwanaansho: Birta birta xagal siman waa wax badan waxaana loo isticmaali karaa codsiyo kala duwan, oo ay ku jiraan qaab-dhismeedyo, iyo taageero
Xagasha 90-Degree: Sida magacaba ka muuqata, birta xagal le'eg waxay leedahay laba lugood oo dherer isku mid ah oo isku xira xagal 90-degree ah, taasoo bixisa xasilooni iyo taageero qaab dhismeedyo kala duwan.
Weldability: Kaarboon xagal siman oo bir ah ayaa si fudud loo alxan karaa, taas oo u oggolaanaysa abuurista qaabab adag iyo naqshado la habeeyey.
MashiinkaBirta kaarboonku guud ahaan way fududahay in la makiinado, taas oo awood u siinaysa samaynta baararka xagasha si ay u buuxiso shuruudaha mashruuca ee gaarka ah.
Iska caabinta daxalka: Iyada oo ku xidhan darajada gaarka ah iyo dhamaadka, kaarboon xagal siman birta ayaa laga yaabaa inay bixiso iska caabbinta daxalka ee gudaha iyo dibadda codsiyada.
Codsiga
Q235B waa shay caadi ahaan loo isticmaalo xaglaha birta, codsiyadeeduna way kala duwan yihiin sababtoo ah sifooyinka iyo sifooyinka birta Q235B.Qaar ka mid ah codsiyada caadiga ah ee xaglaha birta ee Q235B waxaa ka mid ah:
DhismahaXaglaha birta ee Q235B ayaa si weyn loogu isticmaalaa mashaariicda dhismaha ee taageerada qaabdhismeedka, qaabka, iyo xoojinta sababtoo ah xooggooda sare iyo cimri dhererkooda.
Kaabayaasha dhaqaalahaXaglahan birta ah waxaa laga heli karaa mashaariicda kaabayaasha sida buundooyinka, darbiyada haynta, iyo dhismooyinka kale ee injineernimada madaniga ah halkaas oo loo baahan yahay qaybo dhisme oo adag.
Mashiinada iyo Qalabka: Q235B xaglaha birta ah waxaa loo isticmaalaa in wax soo saarka ee mishiinada, frames qalabka, iyo qaab-dhismeedka taageero ay sabab u tahay awoodda ay u qaadaan culaysyo culus oo ay bixiyaan xasilooni.
Farsamaynta: Iyada oo ay weldability iyo machinability, xagal Q235B birta waxaa inta badan loo isticmaalaa in biraha biraha si ay u abuuraan qaybo qaab-dhismeedka habaysan iyo shirarka codsiyada kala duwan.
ACodsiyada qaab dhismeedka iyo qurxintaXaglaha birta ee Q235B waxaa loo isticmaali karaa qaab dhismeed iyo nashqado qurxin si ay u soo jiidato bilicdooda iyo taageerada qaabdhismeed ee dhismaha wejiyada, walxaha qurxinta, iyo qaabdhismeedka farshaxanka.
Codsiyada WarshadahaXaglahan birta ah waxay ka helayaan goobaha warshadaha ee dhismayaal, goobo, taageerooyin, iyo kaabayaasha kale ee looga baahan yahay xarumaha warshadaha.
Iyada oo ay ugu wacan tahay kala duwanaanshaheeda iyo xooggeeda, xaglaha birta ee Q235B waa qaybo muhiim ah oo ka mid ah codsiyada kala duwan ee warshadaha oo dhan, iyaga oo ka dhigaya door caan ah ujeedooyinka qaabdhismeedka iyo dhismaha.
Baakadaha & Rarista
Birta xagasha ayaa guud ahaan loo baakadeeyay si habboon iyadoo loo eegayo cabbirkeeda iyo miisaankeeda inta lagu jiro gaadiidka.Hababka baakadaha caadiga ah waxaa ka mid ah:
Duub: Birta xagasha yar waxaa badanaa lagu duuduubaa bir ama cajalad caag ah si loo hubiyo badbaadada iyo xasiloonida alaabta inta lagu jiro gaadiidka.
Baakadaha birta xagasha galvanized: Haddii ay tahay birta xagasha galvanized, alaabta baakadaha aan biyuhu lahayn iyo qoyaanka, sida filim caag ah oo aan biyuhu lahayn ama kartoon aan qoyaanka ilaalinayn, ayaa badanaa loo isticmaalaa si looga hortago oxidation iyo daxalka.
Baakadaha alwaax: birta xagasha cabirkeedu ka weyn yahay ama miisaankiisu waa lagu baakadeeyay alwaax, sida saqafka alwaax ama kiis alwaax ah, si loo bixiyo taageero iyo ilaalin weyn.
