PDC lossis PCD DRILL BIT?YUAV UA LI CAS?
PDC laum me ntsis txhais tau tias Polycrystalline Pob Zeb Diamond Cutter core ntsis
Cov qhov dej ntxov tshaj plaws yog cov dej qhov dej, qhov tob tob khawb los ntawm txhais tes hauv cov cheeb tsam uas lub rooj dej tuaj txog ntawm qhov chaw, feem ntau yog cov masonry lossis ntoo phab ntsa hauv ob sab phlu.
PDC yog tsim los ntawm kev sib txuas ib co txheej ntawm polycrystalline pob zeb diamond (PCD) nrog ib txheej ntawm cemented carbide liner ntawm qhov kub thiab txias.
PDCs yog cov nruj tshaj plaws ntawm tag nrho cov khoom siv pob zeb diamond.
PCD tsuas txhais tau tias Polycrystalline Pob Zeb Diamond:
PCD feem ntau yog tsim los ntawm sintering ntau micro-size ib pob zeb diamond crystals ntawm qhov kub thiab txias.
PCD muaj qhov zoo ntawm cov pob txha toughness thiab zoo thermal stability, thiab yog siv los ua geological laum khoom.
PDC muaj qhov zoo ntawm pob zeb diamond lub siab hnav tsis kam nrog carbide zoo toughness.
