Weerayaasha fidsan ee birta ah ee culus
Sharaxaada
Dhaqdhaqaaqyada fidsan waxaa loo isticmaalaa in lagu kordhiyo dusha sare ee lowska ama madaxa xiraha si ay u faafiyaan xoogga isku dhufashada aag weyn.Waxay noqon karaan kuwo faa'iido leh marka ay ku shaqeynayaan qalab jilicsan iyo godad qaabaysan oo weyn ama aan caadi ahayn.
Cabbirka dhaqida waxa ay tilmaamaysaa cabbirka daloolka magaciisu yahay oo ku salaysan cabbirka furka.Dhexroorkeeda dibadda (OD) had iyo jeer waa ka weyn yahay.Baaxadda iyo OD waxaa badanaa lagu qeexaa inch jajab ah, in kasta oo inch tobanle la isticmaali karo.Dhumucdiisuna waxay caadi ahaan ku taxan tahay jajab tobanle inkasta oo aynu inta badan u beddelno inch jajab si ay ugu habboonaato.
Fasalka 2-dhaqdhaqaaqyada fidsan waa in lagu isticmaalo oo keliya Fasalka 2 ee biraha koofiyada hex-ga ah - isticmaal weel adag oo fidsan oo leh Fasalka 5 iyo 8 furayaasha.Sababtoo ah Fasalka 2-aad weeliyayaasha fidsan waxay ka samaysan yihiin bir kaarboon oo jilicsan oo hooseeya, waxay "soo saari doonaan" (cadaadi, koob, foorarsi, iwm.) iyagoo hoos imanaya qiyamka qulqulka sare ee sida caadiga ah la xidhiidha furayaasha Fasalka 5 iyo 8.Natiijo ahaan, waxaa hoos u dhici doona xoogga isku-xidhka marka ay dhaqdu soo baxdo.
Dhaqdhaqaaqyada fidsan ayaa caadi ahaan laga helaa agabyo kala duwan oo ay ka mid yihiin aluminium, naxaas, naylon, naxaas silikoon, bir aan dahsoon iyo birta.Birta aan dahaadhka lahayn ama aan dahaadhka lahayn, ee loo yaqaan "dhammaystirka cad," looma daawayn dusha sare si looga hortago miridhku aan ahayn dahaarka khafiifka ah ee saliidda si loogu ilaaliyo ku meel gaadhka ah.Sidaa awgeed, dhamaystirka guud ee birta ayaa ah dahaadhida zinc iyo galvanizing kulul.
CODSIGA
Iyada oo loo marayo naqshadooda, hantida qaybinta ee mashiinnada nadiifka ah waxay ka hortagi karaan nooc kasta oo waxyeello ah oo ku yimaada sagxadaha la soo ururiyey.Makiinada fidsan waxay leedahay oog dhuuban oo fidsan oo dalool dhexda kaga yaal.Dhaqdhaqaaqa noocaan ah wuxuu taageero siiya maro yar oo madaxa ah.
Dhaqdhaqaaqa birta madow-oxide ayaa si khafiif ah u adkaysta daxalka meelaha qalalan.Mashiinnada birta ah ee Zinc-plated waxay u diidaan daxalka meelaha qoyan.Madow ultra-corrosion u adkaysta-dahaarka leh birta dhaqida iska caabiya kiimikada oo u adkeysan 1,000 saacadood oo cusbo buufin ah.
