Farqiga u dhexeeya birta goynta bilaashka ah 1215 iyo 11SMn30 birta

Birta goynta bilaashka ah waxa loola jeedaa birta daawaha ah ee ku daraysa xaddi go'an oo ah hal ama in ka badan curiyayaasha goynta bilaashka ah sida baaruudka, fosfooraska, rasaasta, kaalshiyamka, selenium, tellurium, iwm si loo horumariyo farsamaynteeda.Iyada oo otomaatig ah, xawaaraha sare iyo saxda ah ee goynta, aad bay muhiim u tahay in loo baahdo birta si ay u yeelato mashiin wanaagsan, taas oo inta badan loo isticmaalo ka shaqaynta mashiinnada goynta tooska ah.Kuwa soo socdaa waxay diiradda saarayaan faraqa u dhexeeya 1215 birta goynta bilaashka ah iyo 11SMn30 birta goynta bilaashka ah.

1215 Birta Goynta Bilaashka ah

1215 waa nooc ka mid ah birta goynta fudud ee taxanaha heerka ASTM/AISIBI ee Ameerika.1215 birta goynta bilaashka ah waa shay deegaanka u fiican oo aan ku jirin sunta rasaasta ama walxaha waxyeelada u leh deegaanka.Waxay leedahay sifooyin goyn oo wanaagsan waxayna ku habboon tahay biraha guud ee korantada, qalabka goynta, iyo qaybaha guud.
