Mitundu ya Ma Dayamondi

Mtundu wa diamondi womwe umagwiritsidwa ntchito popera ndi kupukuta zakumwa umakhudza kwambiri magwiridwe antchito a chinthu chomaliza. Ma diamondi a mafakitale amagawidwa m'magulu achilengedwe ndi opanga, ndipo chilichonse chimapangidwa m'njira zosiyanasiyana.

Ufa wa diamondi wachilengedwe nthawi zambiri umapangidwa kuchokera ku diamondi zamtengo wapatali, zomwe, ngakhale sizili zoyenera pamtengo wa miyala yamtengo wapatali, nthawi zambiri zimagwiritsidwa ntchito m'mafakitale. Komabe, diamondi zachilengedwe ndizosowa ndipo zimatha kusiyanasiyana ndi zinthu zachilengedwe.

Ma diamondi opangidwaKumbali ina, zimapangidwa kudzera mu njira zotentha kwambiri/kupanikizika kwambiri. Njirayi imaphatikizapo kugwiritsa ntchito chothandizira chachitsulo kuti chisinthe graphite kukhala diamondi, yomwe nthawi zambiri imatchedwa kuti single-crystal diamond abrasives. Ubwino wa diamondi zopangidwa izi umasiyana kwambiri, kuyambira kuyera kwambiri mpaka kuchuluka kwa kuipitsidwa kwambiri. Single-crystal diamond micro-powder imapangidwa ndi kuphwanya tinthu ta diamondi kenako n’kupanga micronizing ya ufawo, zomwe zimapangitsa kuti ugwiritsidwe ntchito kwambiri.

Mtundu wina wa dayamondi yopangidwa umapangidwa mwa kuphulitsa mabomba omwe amazunguliridwa ndi ndodo za graphite. Kutentha kwakukulu ndi kupanikizika kwa kuphulikako kumasintha graphite kukhala diamondi ya polycrystalline, nthawi zambiri zimapangitsa kuti ma diamondi akhale ochepa kuposa ma micron 10, zomwe zimafunikanso ma micronization kuti zigwiritsidwe ntchito popera ndi kupukuta. Ngakhale kuti ma diamondi a polycrystalline sagwiritsidwa ntchito kwambiri monga ma diamondi a single-crystal, nthawi zambiri amakhala okwera mtengo kwambiri.

Kuphatikiza apo, ma nano-diamondi amapangidwa m'malo olamulidwa mwa kuphulitsa mabomba apulasitiki. Kuphulikako kumapanga zotsalira zokhala ndi ma diamondi ochepa otsika, omwe amadziwika kuti nano-diamonds. Pambuyo poyeretsa ndi kufalitsa, ma nano-diamondi awa nthawi zambiri amakhala ndi ma micron ochepera 1. Ngakhale kuti kupanga kwawo sikovuta kwambiri kuposa kwa ma single-crystal kapena polycrystalline diamondi, sikufanana ndi momwe ma micron akuluakulu amagwirira ntchito popera ndi kupukuta.

Pakati pa zinthu zonse zomwe zimakhudza momwe zinthu zamadzimadzi zimagayidwira komanso kupukutidwa, kukula kwa tinthu tating'onoting'ono n'kofunika kwambiri. Kukula kwa tinthu tating'onoting'ono kumadalira kuchuluka kwa zinthu zomwe zachotsedwa komanso kuuma kwa pamwamba kapena kuchuluka kwa kukanda komwe kumachitika. Ma diamondi onse a kristalo imodzi ndi a polycrystalline amatha kuyesedwa kutengera kukula kwapakati komanso kuchuluka kwa kulekerera.

Ngati mukufuna zinthu zapamwamba za diamondi, funsani Boreas kuti muwongolere luso lanu lopanga ndi mtundu wa zinthu!
