Hana ʻia ʻo PDC Bit Cutter

Kapa ʻia ka mea ʻoki bits PDC he Polycrystalline Diamond Compact Cutter.ʻO kēia mea synthetic he 90-95% daimana maʻemaʻe a hana ʻia i loko o nā compacts i hoʻonohonoho ʻia i loko o ke kino o ka bit. ʻO nā mahana friction kiʻekiʻe i hana ʻia me kēia mau ʻano bits i hopena i ka polycrystalline daimana i haki ʻia a ua hopena kēia i ka hoʻomohala ʻana o Thermally Stable Polycrystalline Diamond - TSP Diamond.

Hoʻokumu ʻia ʻo PCD (Polycrystalline Diamond) i loko o kahi kaʻina hana kiʻekiʻe kiʻekiʻe ʻelua. ʻO ka pae mua o ke kaʻina hana, ʻo ia ka hana ʻana i nā kristal daimana artificial ma ka hōʻike ʻana i ka graphite, i mua o kahi Cobalt, nickel, a me ka hao a manganese catalyst/solution, i ke kaomi ma luna o 600,000 psi. I kēia mau kūlana, hiki koke mai nā kristal daimana. Eia naʻe, i ke kaʻina hana o ka hoʻololi ʻana i ka graphite i daimana, aia ka nui shrinkage, kahi e kahe ai ka catalyst/solvent ma waena o nā crystals e hana ana, e pale ana i ka hoʻopaʻa ʻana i waena a no laila ua hana ʻia kahi pauka aniani daimana mai kēia ʻāpana o ke kaʻina hana.

I ka lua o ke kaʻina hana, hana ʻia ka PCD blank a i ʻole ka 'cutter' e kahi hana sintering wai. ʻO ka pauka daimana i hoʻokumu ʻia i ka pae mua o ke kaʻina hana ua hui pū ʻia me ka catalyst/binder a ʻike ʻia i nā mahana ma luna o 1400 ℃ a me nā kaomi o 750,000 psi. ʻO ke kumu nui o ka sintering, ʻo ia ka hoʻoheheʻe ʻana i nā kristal daimana ma ko lākou mau ʻaoʻao, nā kihi, a me nā wahi o ke kaomi kiʻekiʻe i hoʻokumu ʻia e kahi kiko a i ʻole ka pili ʻana. Hoʻopili ʻia kēia me ka ulu ʻana o ka epitaxial o nā daimana ma nā maka a ma nā wahi o ke kihi pili haʻahaʻa ma waena o nā kristal. Hoʻokumu kēia kaʻina hoʻoulu hou i nā paʻa daimana-i-diamond ʻoiaʻiʻo me ka ʻole o ka mea hoʻopaʻa wai mai ka ʻāpana pili. Hoʻokumu ka mea hoʻopili i kahi pūnaewele mau o nā pores, e noho pū ana me kahi pūnaewele mau o ka daimana. 90-97 vol.%.

Inā makemake kekahi i ka mea hoʻopili i hoʻopaʻa ʻia kahi PCD i hoʻopaʻa kemika i kahi pani tungsten carbide, hiki ke kiʻi ʻia kekahi a i ʻole nā ​​​​mea paʻa a pau no ka PCD mai ka pāpaʻi tungsten carbide e pili ana ma ka hoʻoheheʻe ʻana a me ka hoʻokuʻu ʻana i ka mea hoʻopili cobalt mai ka carbide tungsten.

Inā makemake ʻoe i nā mea ʻoki PDC a makemake ʻoe i nā ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole ka leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
