Kwiminyaka yakutshanje, itekhnoloji yokomba ihambele phambili kakhulu, kwaye enye yezinto ezintsha eziqhuba olu tshintsho sisisiki sePDC. I-PDC, okanye i-polycrystalline diamond compact, abasiki luhlobo lwesixhobo sokomba esisebenzisa indibanisela yedayimane kunye ne-tungsten carbide ukuphucula ukusebenza kunye nokuqina. Aba basiki baye banda kakhulu kwishishini leoli kunye negesi kunye nezinye izicelo zokomba.
Abasiki bePDC benziwa ngokufaka amasuntswana edayimani kwi-tungsten carbide substrate kumaqondo obushushu aphezulu kunye noxinzelelo. Le nkqubo idala into enzima kakhulu kwaye ingagugi ngaphezu kwezinto eziqhelekileyo zokugaya. Isiphumo sisisiki esikwaziyo ukumelana namaqondo obushushu aphezulu, uxinzelelo, kunye ne-abrasion kunezinye izinto zokusika, ezivumela ukugrumba ngokukhawuleza nangokufanelekileyo.
Izibonelelo zabasiki bePDC zininzi. Okokuqala, banokucutha ixesha lokomba kunye neendleko ngokuvumela ukugrumba ngokukhawuleza nangokufanelekileyo. Abasiki bePDC nabo abafanelwanga kukunxiba kunye nokonakala, nto leyo enciphisa isidingo sokutshintshwa rhoqo kunye nokugcinwa. Oku kongela iinkampani ixesha kunye nemali ekuhambeni kwexesha.
Olunye uncedo lwabasiki bePDC kukuguquguquka kwabo. Zingasetyenziswa kwiinkqubo ezahlukeneyo zokomba, kubandakanya ukomba ioyile nerhasi, ukugrumba i-geothermal, imigodi kunye nokwakhiwa. Zikwahambelana nobuchule obahlukeneyo bokomba, njengokugrumba ngokujikelezayo, ukugrumba okuya ngakulo, kunye nokugrumba okuthe tyaba.
Ukusetyenziswa kwee-PDC cutters kuye kwakhokelela ekunciphiseni impembelelo yokusingqongileyo. Ukugrumba ngokukhawuleza nangobuchule kuthetha ixesha elincinci elichithwe kwindawo, nto leyo enciphisa umthamo wamandla kunye nemithombo efunekayo. Ukongeza, abasiki bePDC abafane babangele umonakalo kwindawo engqongileyo, njengokubunjwa kwamatye kunye nemithombo yamanzi angaphantsi komhlaba.
Ukuthandwa kwabasiki bePDC kulindeleke ukuba kuqhubeke ukukhula kwiminyaka ezayo. Ngapha koko, imakethi yehlabathi yabasiki bePDC kulindeleke ukuba ifikelele kwi-1.4 yeebhiliyoni zeedola ngo-2025, iqhutywa kukunyuka kwemfuno evela kumzi-mveliso we-oyile negesi kunye nezinye izicelo zokomba.
Ukuqukumbela, abasiki bePDC baye baguqula itekhnoloji yokomba ngokusebenza kwabo okuphezulu, ukuqina, ukuguquguquka, kunye neenzuzo zokusingqongileyo. Njengoko imfuno yezi zixhobo zokusika iqhubeka nokunyuka, kuyacaca ukuba abasiki bePDC balapha ukuze bahlale kwaye baya kuqhubeka nokudlala indima ebalulekileyo ekuqhubeleni phambili ishishini lokomba.
