PDC, kapena polycrystalline diamondi yaying'ono, odula tsopano asanja masewera pogulitsa ndalama. Zida zodula izi zasintha ukadaulo wobowola mwa kugwiritsa ntchito bwino ntchito komanso kuchepetsa mtengo. Koma kodi odula PDC adachokera kuti, kodi zidatchuka bwanji?
Mbiri ya odula ma PDC imayambiranso zaka 1950 Ma dayamondi awa adapangidwa ndi zojambulajambula ku zovuta zambiri komanso kutentha kwambiri, ndikupanga zinthu zomwe zinali zovuta kuposa diamondi yachilengedwe. Ma diamondi opangidwa mwachangu adatchuka m'mafakitale, kuphatikizapo kubowola.
Komabe, pogwiritsa ntchito ma diamondi opangira mabowo anali ovuta. Ma diamondi nthawi zambiri amasweka kapena deach kuchokera ku chida, kuchepetsa mphamvu yake ndikufuna m'malo pafupipafupi. Kuti tithene ndi vutoli, ofufuza adayamba kuyesa kuphatikiza diamondi yopanga ndi zida zina, monga cangsten Carbide, kuti apange chida chokhacho chodula.
Mu 1970s, odula Oyambirira a PDC adapangidwa, wopangidwa ndi diamondi yolumikizira yolumikizira campride granger. Izi zimagwiritsidwa ntchito poyambirira popanga mabizinesi, koma zopindulitsa zawo zimawonekera m'mafuta ndi mafuta ogwiritsira ntchito mafuta. Odula PDC adapereka mwachangu komanso moyenera kubowola kwambiri, ndikuchepetsa mtengo ndikuwonjezera zokolola.
Monga ukadaulo unakhala bwino, kudula ma PDC kunachulukirachulukira, ndi mapangidwe atsopano ndi zida zowonjezera zolimba komanso zothandiza. Masiku ano, odula a PDC amagwiritsidwa ntchito pobowola ndalama zambiri, kuphatikizapo kubowola kwa ma geothermal, migodi, kumanga, ndi zina zambiri.
Kugwiritsa ntchito odula a PDC kwadzetsanso kupita patsogolo kwa maluso okumba, monga kubowola kopingasa komanso kubowola poyambira. Njirazi zidatheka chifukwa chowonjezera ndi kulimba kwa odulira PDC, kulola kuti muchepetse kutentha.
Pomaliza, odulira PDC ali ndi mbiri yodziwika bwino yomwe ikuchitika m'Chitukuko cha miyala ya miyala ya ma 1950. Chisinthiko ndi chitukuko chawo zadzetsa kupita patsogolo kwakukulu pakukumba, kukonza bwino, kuchepetsa ndalama, ndikuwonjezera ntchito zosiyanasiyana. Monga momwe ndalama zokulira mwachangu komanso zothandiza kwambiri zokulemera, zikuwonekeratu kuti kudula PDC lidzakhala gawo lofunikira kwambiri la msika wobowola.
