ʻO ka hana nui o ka pyrolytic carbon coated high purity hard felt ring ʻo ia ka hāʻawi ʻana i ka hana sealing maikaʻi loa a me ka pale wela. Hiki ke hoʻohana 'ia i loko o nā mea wela wela a me nā kaʻina hana, e like me nā kapuahi wela kiʻekiʻe, nā mea puhi ahi, nā kaʻina hana petrochemical, a me nā mea ʻē aʻe. ʻaʻahu.
ʻO ka uhi kalapona Pyrolytic kahi ʻāpana lahilahi o ke kalapona pyrolytic i uhi ʻia ma ka ʻili o ka isostatic maʻemaʻe loagraphite me ka hoʻohana ʻana i ka ʻenehana chemical deposition (CVD). He kiʻekiʻe kiʻekiʻe, maʻemaʻe kiʻekiʻe, a me anisotropicka wela, ka uila, ka magnetic, a me ka waiwai mechanical.
Nā mea nui:
1. He ʻeleʻele ka ʻili a ʻaʻohe pores.
2. Maʻemaʻe kiʻekiʻe, maʻiʻo haumia piha<20ppm,maikaʻi ka ea.
3.ʻO ke kūpaʻa wela kiʻekiʻe, piʻi ka ikaika me ka piʻi ʻana o ka mahana hoʻohana, hiki i ka mea kiʻekiʻe loawaiwai ma 2750 ℃, sublimation ma 3600 ℃.
4.Haʻahaʻa elastic modulus, kiʻekiʻe thermal conductivity, haʻahaʻa haʻahaʻa hoʻonui hoʻonui ʻana,a maikaʻi hoʻi ke kūʻē i ka haʻalulu wela.
5.ʻO ke kūpaʻa kemika maikaʻi, kū i ka waika, alkali, paʻakai, a me nā reagents organik, a loaʻaʻaʻohe hopena i nā metala i hoʻoheheʻe ʻia, slag, a me nā mea ʻino ʻē aʻe. ʻAʻole ia e oxidizenui loa i ka lewa ma lalo o 400 ℃, a me ka nui o ka oxidationpiʻi ma 800 ℃.
6. Me ka hoʻokuʻu ʻole ʻana i kekahi kinoea i nā wela kiʻekiʻe, hiki iā ia ke mālama i kahi ʻōpala o10-7mmHg ma kahi o 1800 ℃.
Hoʻohana huahana:
1. He'e hoohehee no ka evaporation i lokoʻoihana semiconductor.
2. High mana uila puka puka.
3. Palaki e pili ana i ka mea hoʻoponopono voltage.
4. Graphite monochromator no ka X-ray a me ka neutron.
5. Nā ʻano like ʻole o nā substrates graphite a meka uhi ʻana o ka pahu hoʻoheheʻe atomika.
Pyrolytic carbon coating hopena ma lalo o kahi microscope 500X, me ka ʻili paʻa a sila.
