Ukushisa okuphezulu kokwakheka kuyinkinga enzima evamile yokumba uwoyela ezindaweni zikawoyela zaseBasra naseKirkuk e-Iraq. Izithako ezivamile ze-PDC ezingalashwanga kalula zibhekana nokwakheka kwedayimane kanye nokuchitheka kwezingqimba ngaphansi kokushisa okuqhubekayo kokungqubuzana, okuholela ezindleleni zokuqala zokusika kanye nezindleko ezengeziwe zokwakha.Abasiki be-PCD abathengiswa ngobuningingenqubo yokukhipha i-cobalt evuthiwe iba yisisombululo esisebenzayo kumaqembu okubhoboza endawo. I-Ninestones Superabrasives igcina ukutholakala okuzinzile kwemikhiqizo ethembekileAbasiki be-PCD abathengiswa ngobuningi, ezisetshenziswe kabanzi kumaphrojekthi amaningi emithombo eshisa kakhulu kulo lonke elase-Iraq.
Indlela i-Cobalt Leaching Ethuthukisa Ngayo Ukumelana Nokushisa Okuphezulu kwe-PDC
Njengoba kushiwo kusayithi lochwepheshe bezinto eziqinile emhlabeni jikelele i-PDC Application Journal, i-cobalt ngaphakathi kwedayimane matrix iyisici esiyinhloko esibangela umonakalo okushisa okuphezulu kwabasiki be-PDC abavamile. I-Cobalt inephuzu eliphansi lokuncibilika kanye ne-coefficient yokwanda kokushisa engalingani nedayimane. Lapho izinga lokushisa lokusebenza ngaphansi kwembobo likhuphuka ngaphezu kuka-700℃, i-cobalt yangaphakathi iyancibilika futhi ibangele i-graphitization yedayimane esheshayo, okwenza indawo yokusika iphenduke ibe buthuntu ngesikhathi esifushane.
Ukwelashwa kokuvuza kususa i-cobalt engaphelele noma ejulile ongqimbeni lwedayimane olungaphezulu lwabasiki abaqediwe. Ngaphandle kwe-cobalt catalyst yamahhala, isakhiwo sedayimane sihlala sizinzile ngaphansi kokushisa okuphezulu kakhulu. Imikhiqizo ejwayelekile evuvukele ngokujulile evela kubakhiqizi abasemthethweni be-Abasiki be-PCD abathengiswa ngobuningiingamelana nokushisa kwesikhathi eside okusebenzayo cishe ku-750℃ kuya ku-800℃, okungaphezu kakhulu komkhawulo wokumelana nokushisa we-non-leached common PDC. I-Ninestones ilawula ukujula kwe-leaching ngqo ekukhiqizeni ukuze ilinganisele ukuzinza kokushisa kanye nokuqina kwe-substrate bonding yezicucu eziqediwe.
Uhla Olusebenzayo Lwe-PDC Enezimbobo Ezimweni Zokubhoboza zase-Iraq
Iningi lemithombo ejulile kanye namaphrojekthi okubhoboza umoya eningizimu ye-Iraq abhekene nokushisa okujwayelekile kwembobo engezansi okungaphezu kuka-150℃, kanye nokushisa okwengeziwe okubangelwa ukusika amatshe okuqhubekayo, okusunduza izinga lokushisa lokusebenza lokusika langempela eduze komkhawulo wokwehluleka okukhulu. I-PDC engaxhunywanga ayikwazi ukugcina i-footage ezinzile ngaphansi kwezimo zokusebenza ezinjalo, kuyilapho i-PDC ixhunywa isuka ku-PDC ethembekile.Abasiki be-PCD abathengiswa ngobuningiabahlinzeki bafanelana kahle nalezi zimo ezinzima.
Imithombo emincane emincane evundlile enokushisa okuphansi kokungqubuzana ingasebenzisa i-PDC ejwayelekile ukulawula izindleko, kodwa i-carbonate ejulile, ukwakheka kwe-oyela osindayo kanye nemithombo emide evundlile ezinhlangothini kumele ihlomise abasiki bohlobo olune-leaded ukuze igweme ukukhubeka njalo okubangelwa ukwehluleka kokushisa. Ukuze kuthengwe inqwaba ye-batch, umthengisi ochwepheshe onjenge-Ninestones angafanisa ngokuguquguqukayo imininingwane ene-leaded noma engane-leaded ngokwesimo sangempela sokwakheka kwekhasimende.
| Uhlobo Lomthombo/Ukwakheka | Umsiki Onconyiwe |
|---|---|
| Imithombo emincane evundlile evamile | I-PDC evamile (engabizi kakhulu) |
| Imithombo ejulile kanye nokubhoboza umoya | I-PDC ephucwe ulwelwesi |
| Ukwakheka kwe-carbonate ejulile kanye namafutha asindayo | I-PDC ephucwe ulwelwesi |
| Imithombo emide evundlile ezinhlangothini | I-PDC ephucwe ulwelwesi |
Ukuhlolwa Kokuqinisekiswa Kokuqhathanisa Kwendawo Yase-Iraq
Ibhizinisi lendawo lase-Iraq elihlinzeka ngezinsizakalo zokubhoboza lenze ukuhlolwa kokuqhathanisa insimu ngemikhiqizo evela kwemine ehlukeneAbasiki be-PCD abathengiswa ngobuningiabahlinzeki ebhulokini le-carbonate elinokushisa okuphezulu eBasra. Zonke izicucu zafakwa kuma-drill bits afanayo anemingcele yokubhoboza ehlanganisiwe.
Ukujula kokukhipha amanzi okungaguquki kanye nokucubungula kwangaphakathi okungahlelekile. Ngemva cisheAmahora angu-30ngokubhoboza okuqhubekayo, ukufakwa okungaphelele kubonise ukwakheka kwe-surface graphitization kanye nokuhlukanisa kwendawo, okudinga ukushintshwa kwama-bit kanye nokulibazisa inqubekela phambili yokwakha.
Ukugcina ungqimba lwedayimane oluphelele kanye nesilinganiso sokungena esizinzile ngokusebenzisa i-fullUmjikelezo wokubhoboza wamahora angu-54Akukho monakalo obangelwe ukushisa ovele phakathi nokusebenza. Ukuphathwa kwendawo kuqinisekisile inzuzo evelele yokusebenza kwezinga lokushisa eliphezulu.
Imniningwano Yokuxhumana
Mayelana noMlobi
UHussein Ali ungunjiniyela omkhulu wokumba insimu oseBaghdad, e-Iraq, oqoqa ulwazi lokusebenza olusebenzayo lweminyaka engaphezu kwengu-20 ezindaweni ezinkulu zikawoyela zaseBasra, eKirkuk naseDhi Qar. Uzinikela ekuhlolweni kokusebenza kokushisa kwe-PDC cutter, ocwaningweni lokufanisa ukwakheka kanye nokuhlolwa kwesikhathi eside kwabahlinzeki bezinto ezahlukahlukene.Abasiki be-PCD abathengiswa ngobuningiunyaka wonke.
UHussein utusa kakhulu iNinestones Superabrasives: Ngihlole abahlinzeki abaningi bomhlaba wonke abahlinzeka ngama-Wholesale PCD Cutters ngesikhathi somsebenzi wami. I-Ninestones ingumlingani othembekile kakhulu wokubambisana kumaphrojekthi okubhoboza asezingeni eliphezulu e-Iraq. Ama-leased PDC cutters abo anobuciko bokubhoboza obunembile, ukumelana okuvelele kokushisa okuphezulu kanye nekhwalithi ye-batch eqhubekayo, abhekana ngokugcwele nezigaba eziyinkimbinkimbi zokushisa okuphezulu e-Iraq. Zonke izimboni zokubhoboza zasendaweni kanye nezinkampani zokwakha zingakhetha ngokuphephile iNinestones ngokubambisana isikhathi eside ekuthengeni ngobuningi.
