Chisinthiko cha Odula PDC

Padziko lonse lapansi zobowola, chisinthiko cha PDC (polycrystalline diamondi complect) chakhala chikuyenda bwino pamakampani a mafuta ndi mafuta. Kwa zaka zambiri, odula a PDC ali ndi zosintha kwambiri pakupanga ndikugwira ntchito, kukonza magwiridwe awo ndikuwonjezera nthawi yawo kutalika kwawo.

Poyamba, odula a PDC adapangidwa kuti apereke njira yodalirika komanso yothandiza kwambiri kuyika ma cangsten. Adangodziwitsidwa koyamba m'ma 1970 ndipo mwachangu adatchuka chifukwa chokhoza kuthana ndi kutentha kwambiri komanso zovuta pakugunda kozama. Komabe, kudula koyambirira kwa PDC kunali kochepa ndi mikhalidwe yawo yopanda pake ndipo amakonda kupsinjika ndi kusweka.

Monga ukadaulo wopita patsogolo, opanga adayamba kuyesa zinthu zatsopano ndi kapangidwe kosintha magwiridwe antchito a PDC. Chimodzi mwazinthu zofunikira kwambiri chinali kuyambitsa kwa gawo lokhazikika la peimondi (tsp). Izi kudula diamondi ya diamondi yambiri ndipo imatha kupirira ngakhale kutentha kwambiri ndi zovuta kuposa zodulira za PDC.

Kupambana kwina kwakukulu muukadaulo wa PDC Dution kunali kuyambitsa kwa osakanizidwa. Izi zimaphatikizira kulimba kwa PDC ndi mphamvu ya cangsten kuti apange chida chodulira chomwe chingathetse kugwiritsa ntchito mabotolo omwe angagwiritse ntchito kwambiri.

M'zaka zaposachedwa, tikupita patsogolo m'matedi opanga alola kuti chilengedwe cha ma geometies azidula pa PDC. Izi zadzetsa chitukuko cha ma cutters apadera omwe amapangidwira kuti agwiritse ntchito ndalama zapadera, monga kubowola kwazowongolera ndi kuthamanga kwambiri / kutentha kwambiri.

Chisinthiko cha odula PDC chakhudza kwambiri malonda ndi mafuta. Ndi kuthekera kwawo kupirira mikhalidwe yowopsa komanso yokhazikika kuposa zida zodula, zodula za PDC zachuluka kuti zikuyendetse bwino komanso kuchepetsedwa. Monga momwe ukadaulo wokubadwira ukupitilirabe, mwina tiwona zochitika zina mu kapangidwe ka PDC Duter Ground.

Pomaliza, odula PDC abwera mtunda wautali kuchokera pakumayambiridwa kwa ma 1970. Kuyambira m'masiku awo oyambirirawo ngati njira yokhazikika yolumikizira ma cangsten carbide, pakukula kwa ma cutiter opanga omwe amapangidwa kuti azithamangitsanso kubowola kwina, kusinthika kwa kusintha kwa PDC sikunafupikitsidwe. Makampani opanga mafuta ndi gasi akupitiliza kusinthika, odula a PDC mosakayikira amatenga mbali yovuta poyendetsa bwino ntchito ndi zokolola zobowola.
