I-PDC, okanye i-polycrystalline yedayisi, ii-cutters ziye zaba ngumdlalo we-gamering kwishishini lokuqhuba. Ezi zixhobo zisikiweyo ziguqule itekhnoloji yokumba ngokucutha ngokukhulisa ukusebenza kunye nokunciphisa iindleko. Kodwa bavela phi i-PDC amathayi, kwaye badume njani?
Imbali ye-PDC ihla i-PDC ibuyela kwi-1950s xa kwakuqala iidayimani zokuqala. Ezi dayimani zaveliswa ngokuthoba igrafu ukuya kwiingcinezelo eziphakamileyo kunye namaqondo obushushu, ukudala umbandela omkhulu kunedayimane yendalo. Iidayimani zokwenziwa ngokukhawuleza zathandwa kakhulu zathandwa kwizicelo zemveliso, kubandakanya ukuqhuba.
Nangona kunjalo, ukusebenzisa iidayimani ze-syntichetic ekuqhayiseni kwakunzima. Iidayimani ziya kuqhekeza okanye zinciphise kwesi sixhobo, zinciphisa ukusebenza kwalo kwaye zifune ukutshintshwa rhoqo. Ukulungisa le ngxaki, abaphandi baqala ukuzama ukudibanisa iidayimani ze-syntichetic kunye nezinye izinto, ezinjenge-tungsten ye-tungsten, ukwenza isixhobo esiqinileyo nesifanelekileyo sokusika.
Ngeminyaka yee-1970, zaphuhliswa ii-PDC zokuqala ze-PDC, eziqukethwe ngumaleko wedayimani kwi-sungsten ye-tungsten carbide. Aba basiki basetyenziswa ekuqaleni kwishishini lemigodi, kodwa izibonelelo zabo ngokukhawuleza babonakala kwizicelo zeoyile nakwiigesi. Ii-PDC ezisikiweyo ezinikwa ukuqhuba ngokukhawuleza kunye nokucutha ngakumbi, ukunciphisa iindleko kunye nokwandisa imveliso.
Njengoko itekhnoloji iphuculwe, abasikisi be-PDC baba bahambile, benoyilo olutsha kunye nezixhobo ezikhulisa ukuqina kwazo kunye nokungagqibeki. Namhlanje, ukusika ii-PDC kusetyenziswa kuluhlu olubanzi lwezicelo zokuntywila, kubandakanya ukuqhuba kwe-geothermal, imigodi, ukwakhiwa, nangaphezulu.
Ukusetyenziswa kwee-CDC ze-PDC kukwakhokelela kwinkqubela phambili kwiindlela zokuqhuba, njengokuqhuba ngokuthe tye kunye nokugrumba ngokusondeza. Ezi ndlela zenziwa zinokwenzeka ngokunyuka ngokukuko kunye nokuqina kwe-pdc cutters, zivumela ukuqhuba ngokuthe ngqo kunye nokulawulwa.
Ukuqukumbela, ukusika i-PDC inembali etyebileyo yokuthandana nophuhliso lweedayimani ze-1950s. Ukuzivelela kwabo kunye nophuhliso kuye kwakhokelela kwinkqubela phambili ebalulekileyo kwitekhnoloji yokuqhuba, ukuphucula ukusebenza ngokufanelekileyo, ukunciphisa iindleko, kunye nokwandisa uluhlu lwezicelo. Njengoko imfuno yokuqhuba ngokukhawuleza nangokufanelekileyo ngakumbi iyaqhubeka ikhula, kucacile ukuba abasiki be-PDC baya kuhlala bebaluleke kakhulu kumzi mveliso wokuqhuba.
