Polycrystalline Diamond Carbide Whakauru Moka Patene PDC mo DTH
CLICK_ENLARGE
Ko te Taimana Polycrystalline (PCD) he taimana waihanga. Ko te taputapu PCD he pai ake te aukati i nga kakahu i roto i nga taonga tino abrasive.
Moka patene whakauru PCD Carbide ka kiia e matou he Moka Paatene PDC, ka whakamahia mo te Bit DTH, RC Bit, Top Hammer Bit. Ka whakamahia aua parapara mo te keri kohatu, te keri me te tirotiro whenua.
He moka Polycrystalline Diamond Compact e kiia ana ko PDC Bit me nga parirau 3-7 mo te ahumahi hinu me te hau. Engari ehara i te korero i konei.
Ko te moka PDC me te PCD carbide he roa ake te roa o te mahi i te moka tungsten carbide, ara, mo te 5-7 te roa ake o te oranga. No reira kei te piki haere te rongonui ki te waahi mahi maina.
