Izinto ezimbini ezibalulekileyo zeRaw ye-PDC Cutters

I-PDC cutter luhlobo lwemathiriyeli enzima kakhulu edibanisa idayimani ye-polycrystalline kunye ne-tungsten carbide substrate kubushushu obuphezulu kunye noxinzelelo.

I-PDC Cutter yasungulwa okokuqala nguMbane oMthendeleko (GE) kwi-1971. I-PDC Cutters yokuqala ye-oyile kunye ne-gas imboni ye-oyile yenziwa kwi-1973 kwaye emva kweminyaka eyi-3 yovavanyo kunye novavanyo lwentsimi, ibonakaliswe kakhulu ngakumbi kunezenzo ezityumzayo ze-carbide. amaqhosha amaqhosha ukuze angeniswe ngokorhwebo ngo-1976.

I-PDC Cutters zenziwe nge-tungsten carbide substrate kunye ne-synthetic diamond grit. I-diamond kunye ne-carbide substrate ikhula kunye ngeebhondi zeekhemikhali phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu.

Izinto ezibaluleke kakhulu ze-PDC cutters ziyi-diamond grit kunye ne-carbide substrate.

1. Igrit yedayimani

Igrit yedayimani yeyona nto iphambili ekrwada kubasiki bePDC. Ngokwemichiza kunye neempawu, idayimani eyenziwe ngumntu iyafana nedayimane yendalo. Ukwenza igrit yedayimani kubandakanya inkqubo elula yekhemikhali: ikhabhoni eqhelekileyo ifudunyezwa phantsi koxinzelelo oluphezulu kakhulu kunye nobushushu. Enyanisweni, ukwenza idayimani akulula.

I-Diamond grit ayizinzile kangako kumaqondo obushushu aphezulu kunedayimane yendalo, nangona kunjalo. Ngenxa yokuba i-metallic catalyst ebanjelwe kulwakhiwo lwegrit inezinga eliphezulu lokwandiswa kwe-thermal kunedayimani, ukwandiswa kokwahluka kubeka iibhondi zedayimane ukuya kwi-diamond phantsi kwe-chear kwaye, ukuba imithwalo iphezulu ngokwaneleyo, ibangela ukusilela kweebhondi. Ukuba iibhondi zisilela, iidayimani zilahleka ngokukhawuleza, ngoko ke iPDC ilahlekelwa bubulukhuni kunye nokubukhali kwayo kwaye ingasebenzi. Ukuthintela ukusilela okunjalo, abasiki bePDC kufuneka zipholiswe ngokwaneleyo ngexesha lokomba.

2. I-Carbide substrate

I-Carbide substrate yenziwe nge-tungsten carbide. I-Tungsten carbide (ifomula yeekhemikhali: WC) yikhemikhali yekhemikhali equkethe i-tungsten kunye ne-athomu ye-carbon. Eyona ndlela isisiseko ye-tungsten carbide ngumgubo ongwevu ocolekileyo, kodwa unokucinezelwa kwaye wenze iimilo ngokucinezela kunye nokuntywila.

I-Tungsten carbide isetyenziswa kakhulu emigodini kwimibhobho yokwembiwa kwehamile ephezulu, iihamile zomngxuma ophantsi, ii-roller-cutters, iitshiseli zekhuba ezinde, iipeki zokucheba ezinde, ukuphakamisa izixhobo ezikruqulayo, kunye noomatshini abadika itonela.

I-Zzbetter inolawulo olungqongqo lwemathiriyeli ekrwada yegrit yedayimane kunye ne-carbide substrate. Ukwenza i-PDC cutter oilfield yokugrumba, sisebenzisa idayimane evela kumazwe angaphandle. Kwakhona kufuneka siyiqhekeze kwaye siyibumbe kwakhona, senze ubungakanani be-particle size ifanane. Kwakhona kufuneka sihlambulule izinto zedayimani. Sisebenzisa iLaser Particle Size Analyzer ukuhlalutya ukuhanjiswa kobungakanani besuntswana, ubunyulu, kunye nobukhulu kwibhetshi nganye yedayimane yomgubo. Sisebenzisa iipowders ezinyulu ezikumgangatho ophezulu ezinamabakala afanelekileyo ukuvelisa i-tungsten carbide substrates.

E-Zzbetter, sinokunika uluhlu olubanzi lwabasiki abathile.
