Birta aan lahayn Birta
Sharaxaada Alaabta
Shayga birta ah ee birta ah waa qayb xagal ah oo birta ah.Waxaa loo isticmaali karaa in lagu beddelo noocyo kala duwan oo macdanta ah iyo kuwa aan biraha ahayn, sida alumina, carbide silicon, ciid quartz, kuul dhalo ah, iwm.
Xabagta birta ah ee birta ah waxaa inta badan loo isticmaalaa nadiifinta dusha sare, ka saarista rinjiga iyo baabi'inta biraha aan birta ahayn iyo alaabta birta ah, samaynta qallafsanaanta dusha sare, sidaas darteed gaar ahaan ku habboon prereatment dusha ka hor daahan.Marka la barbar dhigo kuwa aan biraha ahayn, birta birta ah waxay kaa caawinaysaa yaraynta kharashaadka hawlgalka iyo sii deynta siigada iyo hagaajinta jawiga shaqada.
Birta birta ah waxay leedahay nolol adeeg dheer iyo hufnaan sare oo qarxin ah, fududaynta habka qarxinta, badbaadinta kharashka, gaaritaanka tayada qarxinta xasilloon, qallafsanaanta isku midka ah iyo muuqaalka.
