PDC A I ʻole PCD DRILL BIT ?He aha ka ʻokoʻa?
ʻO ka bit drill PDC ʻo ia hoʻi ʻo Polycrystalline Diamond Cutter core bit
ʻO nā pūnāwai mua loa he mau lua wai, nā lua pāpaʻu i ʻeli ʻia e ka lima ma nā wahi i kokoke aku ai ka wai i ka ʻili, maʻa mau me nā pā pōhaku a i ʻole nā paia lāʻau.
Hana ʻia ʻo PDC ma ka hui ʻana i kekahi mau papa o nā daimana polycrystalline (PCD) me kahi papa o ka liner carbide cemented i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe.
ʻO nā PDC kekahi o nā mea paʻa loa o nā mea hana daimana.
ʻO ka PCD wale nō ke ʻano o ka Polycrystalline Diamond :
Hana ʻia ʻo PCD ma o ka sintering ʻana i nā kristal daimana hoʻokahi micro-nui ma ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe.
ʻO ka PCD ka paʻakikī haʻihaʻi maikaʻi a me ke kūpaʻa wela maikaʻi, a hoʻohana ʻia i ka hana ʻana i nā ʻāpana drill geological.
Loaʻa i ka PDC ka maikaʻi o ke kūpale kiʻekiʻe o ke daimana me ka paʻakikī maikaʻi o ka carbide.
