Polycrystalline Diamond Carbide Fa'aofi le PDC Button Bit mo le DTH
CLICK_ENLARGE
Polycrystalline Diamond (PCD) o se taimane gaosia. O meafaigaluega PCD e maua ai le fa'aofuofu sili atu i mea e sili ona abrasive.
PCD Carbide insert button bit matou taʻua o le PDC Button Bit, e masani ona faʻaaogaina mo le DTH Bit, RC Bit, Top Hammer Bit. O fasimea ia e fa'aaogaina mo le eliina o ma'a, eli ma su'esu'ega fa'afanua.
O loʻo i ai le isi Polycrystalline Diamond Compact bit lea e taʻua foi o le PDC Bit ma 3-7 apaau mo le suauʻu ma le kesi. Ae e le o tatou talanoa iinei.
O le PDC bit ma PCD carbide e sili atu le umi o lona olaga nai lo le tungsten carbide bit, o lona uiga, e tusa ma le 5-7 taimi umi le olaga. O lea ua atili ai ona ta'uta'ua i nofoaga o galuega eli.
