Polycrystalline Pob Zeb Diamond (PCD) yog pob zeb diamond hluavtaws. PCD cov cuab yeej muab kev hnav zoo tshaj plaws hauv cov ntaub ntawv abrasive heev.
PCD Carbide ntxig khawm me ntsis peb hu nws PDC Button Bit, feem ntau yog siv rau DTH Bit, RC ntsis, Sab saum toj rauj ntsis. Cov khoom siv no yog siv rau kev khawb pob zeb, mining thiab tshawb nrhiav geological.
Muaj lwm qhov Polycrystalline Pob Zeb Diamond Compact me ntsis uas tseem hu ua PDC Bit nrog 3-7 tis rau kev lag luam roj thiab roj. Tab sis nws tsis yog peb tham ntawm no.
PDC me ntsis nrog PCD carbide muaj ntau lub neej ua haujlwm ntev dua li tungsten carbide me ntsis, piv txwv li, txog 5-7 lub sijhawm ntev dua lub neej. Yog li nws tau txais ntau thiab nrov nyob rau hauv mining worksite.
