Umehluko phakathi kwe-PDC ne-PCD

I-PDC ne-PCD zombili ziyizinto ezintsha eziqinile. Uyini umehluko phakathi kwabo?

I-PCD (i-Polycrystalline Diamond) yenziwe ngegrit yedayimane. Igrit yedayimane ihlanganiswe ngaphansi kwezimo ezinomfutho ophezulu, nezinga lokushisa eliphezulu phambi kwensimbi ye-catalytic. I-PCD inobulukhuni obedlulele, ukumelana nokugqokwa, kanye nokuguquguquka okushisayo kwedayimane, okwenza i-PCD ibe into efanelekile yokwenza amathuluzi okusika. Amathuluzi e-PCD (njenge-PCD insert kanye nama-PCD blades) angakwazi umshini zonke izinto ezingezona ayoni njengalezo ezisetshenziswa embonini yokwenza ukhuni, ama-chipboards, i-HDF, namabhodi aminated. I-PCD isetshenziswa embonini yezimoto ukukhiqiza izingxenye ze-aluminium nazo zonke izinto ezingasindi ezifana ne-carbon fiber reinforced plastic (CFRP), izinhlanganisela ze-metal matrix (MMC), kanye nezitaki zokwakhiwa kwezindiza.

I-PDC (I-Polycrystalline Diamond Compact) ibhekisela kuyinhlanganisela yedayimane ye-polycrystalline noma ehlangene, okuyithuluzi eliqinile kunazo zonke phakathi kwazo zonke izinto zamathuluzi edayimane. Yenziwa ngokuhlanganisa ezinye izingqimba zamadayimane e-polycrystalline (PCD) nongqimba lwe-carbide substrate enosimende ekushiseni okuphezulu nokucindezela okukhulu. Izinga lokushisa lizungeze i-1400 ~ 1700 ℃, futhi ingcindezi izungeze i-6-7 GPA. I-cobalt alloy ikhona futhi isebenza njenge-catalyst yenqubo ye-sintering. I-cobalt isiza ukubopha i-carbide nedayimane. I-PDC inezinzuzo zokumelana nokugqoka okuphezulu kwedayimane nokuqina okuhle kwe-carbide.

Izinzuzo Eziyinhloko ze-PDC

Ukumelana nokugqoka okuphezulu

Ukumelana nomthelela ophezulu

Ukuzinza okuphezulu kokushisa

Impilo yokusebenza yabasiki be-PDC ikhuphuka izikhathi ezingaphezu kwe-6 ~ 10

Yehlisa imvamisa yokushintshwa kwezingcezu zokumba kanye namandla okusebenza kwabasebenzi.

Ngenxa yokusebenza kwabo okuphezulu, abasiki be-PDC basetshenziswa kabanzi kulezi zici ezingezansi:

Izicucu ze-PDC zikawoyela negesi njengobuso, igeji, nezisiki eziyisipele

Izingcezu ze-PDC zokumba i-geothermal

Izingcezu ze-PDC zokumba umthombo wamanzi

Izingcezu ze-PDC zokumba isiqondiso

Lapha kwa-zzbetter, Sinikezela ngomumo obanzi nobubanzi be-PDC cutters.

Umumo we-zzbetter PDC Cutter

1. Umsiki we-PDC oyisicaba

2. Inkinobho ye-PDC eyindilinga

3. Inkinobho ye-Parabolic PDC, inkinobho yangaphambili

4. Inkinobho ye-Conical PDC

5. Abasiki be-PDC abayisikwele

6. Abasiki be-PDC abangajwayelekile

Uma unentshisekelo kubasiki be-PDC futhi ufuna ulwazi olwengeziwe kanye nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE I-IMEYILI ezansi nekhasi.
