Saxan Bir ah oo AR400 ah

Sawirka La Soo Bandhigay ee Saxanka Birta ah ee AR400

Sharaxaad Gaaban:

Saxanka birta ah ee u adkaysta abrasion-ka (AR) waa saxan bir ah oo kaarboon sare leh. Taas macnaheedu waa in AR ay adag tahay sababtoo ah ku darista kaarboonka, waana mid samaysan kara oo u adkaysta cimilada sababtoo ah daawaha lagu daray.

Codsiyada Saxanka Birta ee Abrasion u adkaysta

● Taarikada AR235 waxaa loogu talagalay in lagu isticmaalo xirashada dhexdhexaadka ah halkaas oo ay bixiso iska caabin xirasho oo wanaagsan marka loo eego birta kaarboonka qaab-dhismeedka.
● AR400 waa saxanno bir ah oo u adkaysta xoqidda sare, kuwaas oo kulaylka lagu daweeyay oo si fiican u adkaysta. Awoodaha sameynta iyo agabka la isku qurxiyo oo la hagaajiyay.
● AR450 waa saxan u adkaysta xoqidda oo loo isticmaalo codsiyo kala duwan halkaas oo la doonayo xoog ka weyn kan AR400.
● Taarikada AR500 waxay ku habboon yihiin macdan qodista, kaymaha iyo codsiyada dhismaha.
● AR600 waxaa loo isticmaalaa meelaha aadka u duugoobay sida ka saarista guud, qodista, iyo soo saarista baaldiyada iyo meydadka duugoobay.
Saxanka birta ah ee u adkaysta xoqidda (AR) waxaa badanaa lagu sameeyaa xaalad la duubay. Noocyadan/darajooyinkan alaabada birta ah waxaa si gaar ah loogu sameeyay cimri dheer oo adeeg ah xaaladaha adag. Badeecadaha AR waxay ku habboon yihiin codsiyo kala duwan oo ku saabsan meelaha sida macdan qodista/goynta, qalabka wax lagu qaado, maaraynta agabka iyo dhismaha, iyo dhaqdhaqaaqa dhulka. Naqshadeeyayaasha iyo hawl wadeennada warshadda waxay doortaan birta saxanka AR marka ay ku dadaalayaan inay kordhiyaan cimriga adeegga ee qaybaha muhiimka ah, iyo inay yareeyaan miisaanka cutub kasta oo la geliyo adeegga. Faa'iidooyinka isticmaalka birta saxanka u adkaysta xirashada ee codsiyada ku lug leh saameynta iyo/ama taabashada simbiriirixan ee walxaha xoqidda waa kuwo aad u weyn.

Taarikada birta ah ee u adkaysta xoqidda guud ahaan waxay bixiyaan iska caabin wanaagsan oo ku wajahan xoqidda iyo saameynta. Kaarboonka badan ee ku jira dahaarka ayaa kordhiya adkaanta iyo adkeysiga birta, taasoo ka dhigaysa agab ku habboon codsiyada u baahan saameyn sare ama iska caabin xoqid sare. Waa suurtagal in la helo adkeysi sare oo leh bir kaarboon sare, birtuna waxay yeelan doontaa iska caabin wanaagsan oo ku wajahan gelinta. Si kastaba ha ahaatee, heerka xirashadu wuxuu noqon doonaa mid degdeg ah marka la barbar dhigo saxanka dahaarka ee kulaylka lagu daweeyay sababtoo ah birta kaarboon sare waa mid jilicsan, sidaa darteed walxaha si fudud ayaa looga jeexi karaa dusha sare. Natiijo ahaan, birta kaarboon sare looma isticmaalo codsiyada xirashada sare.
