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, maʻamau 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 ke kiʻekiʻe 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.
