Birta Xagalka Kaarboon Sare ee Birta
Qaabka/Xajmiga:G12-G150 Φ0.1mm-2.8mm
Faahfaahinta Alaabta:
Bir kaarboon xagal sare oo bir ah ayaa laga soo saaray toogashada birta kaarboonka sare.Tallaabooyin bir ah oo la jajabiyey si ay u sameysmaan qaab granular ah oo ka dibna u dabcay saddex adag oo kala duwan (GH, GL iyo GP) si ay u daboolaan codsiyada kala duwan.Birta kaarboonka sare ee birta ah ayaa si weyn loogu isticmaalaa warbaahin ahaan si loo dhimo qaybaha birta ka hor inta aan dahaadhka la saarin.

Tallaabooyinka Habaynta:
Codsiyada:
Birta Kaarboon Sare ee Grit GP:Leh adayga ugu hooseeya inta u dhaxaysa 40 ilaa 50 HRC waxaana sidoo kale loo qaddariyaa tallaal xagal ah, sababtoo ah barafku wuxuu heli doonaa qaab wareegsan inta uu nool yahay.Waxaa inta badan loo isticmaalaa mashiinada qarxinta giraangiraha waxayna natiijooyin wanaagsan ku leedahay warshadaha aasaaska sababtoo ah waxay si dhakhso ah u nadiifisaa iyadoo ay yar tahay kor u kaca kharashka dayactirka iyo xirashada qaybaha mashiinka.GP-ga waxa loo isticmaalaa nadiifinta, nadiifinta iyo soo saarida.
Sare ee Kaarboon Steel Grit GL:Leh qallafsanaan dhexdhexaad ah inta u dhaxaysa 50 ilaa 60 HRC.Waxaa loo adeegsadaa mashiinnada qaraxa giraangiraha ah iyo qolalka qaraxa waxayna si gaar ah ugu habboon tahay goynta culus iyo shuruudaha diyaarinta dusha sare.In kasta oo GL uu yahay mid adag, waxa kale oo uu lumiyaa qaabkeeda xagal inta lagu jiro qarxinta rasaasta.
Sare Kaarboon Steel Grit GH: Adaggu ugu badnaan wuxuu u dhexeeyaa 60 ilaa 64 HRC.Waxa ay xagal ku ahaanaysaa isku dhafka hawlgalka, sidaas darteedna waxay ku habboon tahay shuruudaha xoqidda dusha sare.GH waxaa badanaa lagu isticmaalaa qolalka qaraxa (qalabka fidinta toogashada hawada la cadaadiyo
