Kusiyana pakati pa PDC ndi PCD

PDC ndi PCD onse ndi zida zatsopano zolimba kwambiri. Kodi pali kusiyana kotani pakati pawo?

PCD (Polycrystalline Diamond) amapangidwa kuchokera ku grit ya diamondi. Grit ya diamondi yasakanizidwa pansi pa kupanikizika kwakukulu, kutentha kwakukulu pamaso pa chitsulo chothandizira. PCD ili ndi kuuma kwambiri, kukana kuvala, komanso kutenthetsa kwa diamondi, zomwe zimapangitsa PCD kukhala chinthu choyenera kupanga zida zodulira. Zida za PCD (monga PCD insert ndi PCD blades) zimatha kusindikiza zinthu zonse zopanda chitsulo monga zomwe zimagwiritsidwa ntchito popanga matabwa, chipboards, HDF, ndi matabwa a laminated. PCD ikugwiritsidwa ntchito m'makampani opanga magalimoto kupanga zida za aluminiyamu ndi zida zonse zopepuka monga mapulasitiki opangidwa ndi kaboni fiber (CFRP), ma composites achitsulo (MMC), ndi milu yomanga ndege.

PDC (Polycrystalline Diamond Compact) amatanthauza polycrystalline diamondi gulu kapena yaying'ono, chomwe ndi chida cholimba kwambiri pakati pa zida zonse za diamondi. Amapangidwa pophatikiza zigawo zina za diamondi za polycrystalline (PCD) ndi gawo la simenti ya carbide pa kutentha kwambiri komanso kuthamanga kwambiri. Kutentha kuli mozungulira 1400 ~ 1700 ℃, ndipo kupanikizika kuli pafupi 6-7 GPA. Aloyi ya cobalt iliponso ndipo imagwira ntchito ngati chothandizira kuti sintering. Cobalt imathandizira kugwirizana kwa carbide ndi diamondi. PDC ili ndi zabwino zake zokana kuvala kwa diamondi ndi kulimba kwabwino kwa carbide.

Ubwino Wachikulu wa PDC

High kuvala kukana

Kukana kwakukulu

Kukhazikika kwamafuta apamwamba

Moyo wogwira ntchito wa odula a PDC ukuwonjezeka ndi nthawi zopitilira 6 ~ 10

Kuchepetsa kuchulukirachulukira kwa nthiti zobowola komanso kuchuluka kwa ogwira ntchito.

Chifukwa cha magwiridwe antchito apamwamba, odula a PDC amagwiritsidwa ntchito kwambiri pazinthu zotsatirazi:

PDC yamafuta ndi gasi imakhala ngati nkhope, geji, ndi zodulira zosunga zobwezeretsera

PDC bits pobowola geothermal

PDC bits pobowola madzi

PDC bits pobowola molunjika

Kuno ku zzbetter, Timapereka mawonekedwe ndi kukula kwa odula a PDC.

Mawonekedwe a zzbetter PDC Cutter

1. Wodula PDC wokhazikika

2. Bulu la PDC lozungulira

3. Parabolic PDC batani, kutsogolo batani

4. Conical PDC batani

5. Odula PDC Square

6. Odula PDC osakhazikika

Ngati mukufuna zodula za PDC ndipo mukufuna zambiri ndi zambiri, mutha KULAMBIRA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZENI MAIL pansi pa tsambali.
