AR400 Birta birta ah

Sharaxaad Gaaban:

Saxan bir ah oo adkaysi u leh abrasion (AR) waa saxan bir ah oo kaarboon ah oo sarreeya. Tani waxay ka dhigan tahay in AR ay adag tahay marka lagu daro kaarboonka, iyo qaabaysan oo cimilada u adkeysanaya sababtoo ah alwaaxyada lagu daray.

Codsiyada saxanka u adkaysta nabarka

● Taarikada AR235 waxaa loogu talagalay codsiyada xirashada dhexdhexaadka ah halkaasoo ay ka bixiso iska caabbinta xirashada oo soo hagaagtay marka loo eego qaab dhismeedka kaarboonka.
AR400 waa taargooyin bir ah oo u adkaysta nabarka kuwaas oo kulaylka lagu daweeyay oo muujinaya adkeyn. Awoodaha samaynta iyo arooska oo la hagaajiyay.
AR450 waa saxan u adkaysta nabarka oo loo isticmaalo codsiyo kala duwan halkaasoo xoog wax yar ka weyn laga rabo AR400.
● Taarikada AR500 waxay ku habboon yihiin macdanta, kaymaha iyo codsiyada dhismaha.
AR600 waxaa laga isticmaalaa meelaha dharka aadka u sarreeya sida ka saarista wadarta guud, macdanta, iyo samaynta baaldiyada iyo maydadka xidhashada.
Saxan bir ah oo iska caabin ah (AR) ayaa sida caadiga ah lagu sameeyaa xaalada sida duuban. Noocyada noocaan ah ee alaabta saxanka birta ah ayaa loo sameeyay si gaar ah nolosha adeegga muddada dheer ee xaaladaha adag. Alaabooyinka AR waxay ku habboon yihiin codsiyada kala duwan ee meelaha sida macdan qodista/dharka dhagaxa, maraakiibta, maaraynta alaabta iyo dhismaha, iyo dhaqdhaqaaqa dhulka. Naqshadayaasha iyo hawl wadeenada warshaduhu waxay doortaan birta saxanka ah ee AR marka ay ku dadaalayaan inay kordhiyaan nolosha adeega qaybaha muhiimka ah, oo ay yareeyaan miisaanka qayb kasta oo adeega la geliyo. Faa'iidooyinka ku jira adeegsiga birta birta ah ee xidhashada u adkaysata ee codsiyada ku lug leh saamaynta iyo/ama taabsiinta taabashadu waa mid aad u weyn.

Taarikada birta daawaha u adkeysata ee abrasive waxay guud ahaan bixiyaan iska caabin wanaagsan simbiriirinta iyo saamaynta Maaddooyinka sare ee kaarboonka ee daawaha waxay kordhisaa adkaanta iyo adkaanta birta, taas oo ka dhigaysa qalab ku habboon codsiyada u baahan saameyn sare ama iska caabin sare. Waxaa suurtogal ah in lagu helo qallafsanaan sare leh bir kaarboon sare leh, birta waxay yeelan doontaa iska caabin wanaagsan oo ah dhexgalka. Si kastaba ha ahaatee, heerka xidhiddu wuxuu noqon doonaa mid degdeg ah marka la barbar dhigo kulaylka lagu daweeyaa saxan daawaha sababtoo ah birta kaarboon sare waa jajaban, si qayb ka mid ah si fudud ayaa laga jeexjeexi karaa dusha sare. Natiijo ahaan, birta kaarboonka sare looma isticmaalo codsiyada xidhashada sare.
