Ubushuhe buhamye Polycrystalline Diamond Bit Cutter
Ubushuhe buhamye Polycrystalline Diamond Bit Cutter
Ubushuhe buhamye bwa polycrystalline ya diamant biti yatangijwe mugihe wasangaga ibyuma bya PDC bitemwa rimwe na rimwe mugihe cyo gucukura. Uku kunanirwa kwatewe nihungabana ryimbere ryatewe no kwaguka gutandukanye kwa diyama nibikoresho.
Cobalt nigikoresho gikoreshwa cyane mubicuruzwa bya PCD byacumuye. Ibi bikoresho bifite coefficente yumuriro yo kwaguka 1,2 x 10 ^ -5 deg. C ugereranije na 2.7 x 10 ^ -6 kuri diyama. Kubwibyo cobalt yaguka vuba kurusha diyama. Nkuko ubushyuhe bwinshi bwikibiriti buzamutse hejuru ya 730 deg C guhangayikishwa nimbere biterwa nigipimo gitandukanye cyo kwaguka biganisha kumeneka rikomeye hagati yimiterere, gukata macro, no kunanirwa byihuse.
Ubu bushyuhe buri hejuru cyane yubushyuhe bwo kuboneka hepfo ya boreho (mubisanzwe 100 deg C kuri 8000 ft). Zikomoka ku guterana kwatewe nigikorwa cyo kogosha ibyo bice bitema urutare.
Ubu bushyuhe bwa 730 deg C bwerekanye inzitizi zikomeye zo kunoza imikorere ya PCD ikata.
Ababikora bakoze ubushakashatsi mugutezimbere ubushyuhe bwumuriro wibyuma kandi ibyuma bya diyama biti bya polycrystalline bihamye.
Utubuto twa bits duhagaze neza mubushyuhe bwo hejuru kuko bober ya cobalt yakuweho kandi ibi bikuraho imihangayiko yimbere iterwa no kwaguka gutandukanye. Kubera ko ibyinshi mu bihuza bifitanye isano, kuvura kwagutse hamwe na acide birashobora gusohoka hafi yabyo. Isano iri hagati ya diyama yegeranye ntishobora kugira ingaruka, igumana 50-80% yingufu zamasezerano. PCD yamenetse ihagaze neza mubushuhe cyangwa kugabanya ikirere kugera kuri dogere 1200 ariko bizamanuka kuri 875 deg C imbere ya ogisijeni.
Byaragaragaye ko niba ibikoresho bya cobalt bishobora gukurwa mu cyuho cy’ingano, ituze ry’ubushyuhe bw’amenyo ya PDC rizanozwa cyane ku buryo biti ishobora gucukura neza mu buryo bukomeye kandi butera ubwoba. Ubu buryo bwo kuvanaho cobalt bwongera imbaraga zo kwambara amenyo ya PDC muburyo bukomeye bwangiza kandi bikagura intera ikoreshwa ya bits ya PDC.
Kubindi bisobanuro kubyerekeye abakata PDC, murakaza neza kudusura kuri www.zzbetter.com
