Ukugrumba ioyile negesi

I-oyile negesi yokubhola isebenzisa iphepha ledayimani elidibeneyo elijikelezileyo
Umatshini wokuhlola ioyile negesi weWuhan Ninestones Superabrasives Co., Ltd usebenzisa i-PDC ejikelezileyo kwaye unokubonelela ngeemveliso ngeenkcukacha ezahlukeneyo ukusuka kwi-5mm ukuya kwi-30mm ububanzi. Ngokweeyantlukwano kukumelana nokuguguleka, ukumelana nempembelelo kunye nokumelana nobushushu kweemveliso zePDC, kukho uthotho lweemveliso ezintlanu eziqhelekileyo ngolu hlobo lulandelayo.

Umfanekiso 1 Imephu yemveliso yePDC ye-polycrystalline diamond compact

Uthotho lwe-GX: iphepha elidityanisiweyo elisemgangathweni wokusebenza ngokubanzi, elenziwe phantsi kweemeko zoxinzelelo oluphezulu (5.5GPa-6.5GPa), ukumelana nokuguguleka okulinganayo kunye nokumelana nempembelelo, ukusebenza okubiza kakhulu, okufanelekileyo ukugrumba kwiindawo ezithambileyo ukuya kweziphakathi kunye neebhithi zokugrumba ezisebenza kakhulu Ukusetyenziswa kwiindawo ezingezizo ezibalulekileyo ezifana namazinyo ancedisayo.
Uthotho lwe-MX: iphepha elidityanisiweyo eliphakathi, elenziwe phantsi koxinzelelo oluphezulu kakhulu (6.5GPa-7.0GPa), elinokumelana nokuguguleka okulinganayo kunye nokumelana nempembelelo, elifanelekileyo ukugrumba kwiindawo ezithambileyo ukuya kweziphakathi eziqinileyo, elizilolayo kakuhle, ngakumbi ezifanelekileyo kwiindawo zokugrumba ngesantya esiphezulu somatshini, likwalungelelana kakuhle neendawo zeplastiki ezifana nelitye lodaka.
Uthotho lwe-MT: Iphepha elidityanisiweyo elimelana nempembelelo ephakathi, ngoyilo lokwenza ngcono isakhiwo somgubo kunye ne-matrix eyahlukileyo kunye nenkqubo yobushushu obuphezulu kunye noxinzelelo oluphezulu, eyenziwe phantsi kweemeko zoxinzelelo oluphezulu kakhulu (7.0GPa-7.5GPa), ukumelana nokuguguleka kuyafana nephepha elidityanisiweyo eliphakathi eliphakathi elisetyenziswa ekhaya. Ukumelana nokuguguleka kuyafana, kwaye ukumelana nokuguguleka kudlula kakhulu inqanaba leemveliso zenqanaba elifanayo. Ifanelekile ukugrumba kwiindlela ezahlukeneyo, ngakumbi iindlela ezinee-interlayers.
Uthotho lwe-X7: amaphepha ahlanganisiweyo apheleleyo aphezulu, enziwe phantsi kweemeko zoxinzelelo oluphezulu kakhulu (7.5GPa-8.5GPa), enokumelana nokuguguleka okuphezulu kakhulu kunye nokumelana okuzinzileyo kwempembelelo, ukumelana nokuguguleka kufikelele kwinqanaba lokuqala lasekhaya, elifanelekileyo kwi-Drilling ephakathi ukuya kwenzima kwiimeko ezahlukeneyo zokusebenza ezintsonkothileyo zezakhiwo, ngakumbi kwizakhiwo zamatye aphakathi kunye nesanti ye-quartz eninzi, i-limestone kunye nee-interlayers.
Uthotho lwe-AX8: iphepha elidityanisiweyo elinoxinzelelo oluphezulu kakhulu, elenziwe phantsi kweemeko zoxinzelelo oluphezulu kakhulu (8.0GPa-8.5GPa), ubukhulu bomaleko wedayimani bumalunga ne-2.8mm, kwaye linokumelana okuphezulu kakhulu kokuguguleka ngenxa yokumelana okuphezulu kwempembelelo. Lifanelekile kwiindlela ezahlukeneyo zokubhola zeFomation, ngakumbi ezifanelekileyo ekubhobheni kwiindawo ezinzima ezifana neendawo eziphakathi kunye neendawo ezidibeneyo.
