(Kutentha kotentha kwa ceractic yopangidwa ndiWntrustek)

Mwakutero, kutentha kotentha kwa uchimo ndi njira yopumira kwambiri yolimbika. Ngakhale momwe mawonekedwe ake achitsanzo amasiyanasiyana, njira yoyambira ndiyofanana: ufa umadzaza mu ufa pogwiritsa ntchito nkhokwe zapamwamba ndi zotsika pomwe zimakwaniritsidwa.

Matayala, magiya, Zisindikizo, ndi zinthu zina zofunika pamafakitale osiyanasiyana zimatha kupangidwa ndi kachilombo kotentha. Zipangizo kuphatikiza ceramics, ufa wachitsulo, ufa wa polymer, ndi zopangira zomwe ndizovuta kuti ochimwa pogwiritsa ntchito njira zamitundu yogwiritsira ntchito ndioyenera kwambiri njirayi. Ocheza achinyengo amatha kupanga utoto wachitsulo kapena zinthu zophatikizika ndi kachulukidwe kwambiri kuposa kuchimwa.

Ubwino:

• Kulimba kwambiri komanso kulimba

• Khalidwe labwino

• Kuwongolera kolondola

• Mapeto ake

• Kuchepetsa mtengo wopangira

• Kuchepetsa nthawi yochimwa

Ubwino wa owotchera ultering poyerekeza ndi ochimwa kwambiri:

Kuphatikiza pa kutsitsa kuzolowera, kulowa munthawi yomweyo komanso kutsitsa kungachepetse kutentha kwa uchimo, kuchepetsa nthawi yochimwa, komanso kupewa kukula kwa tirigu. Kuchulukitsa kwambiri, mbewu zabwino, komanso mikhalidwe yapamwamba ndi zamagetsi ndizomwe zimapangidwa ndi zinthu zomaliza. Kwambiri, kusindikizidwa kotentha kumatha kupanga zinthu zapamwamba kwambiri zokhala ndi zoyera popanda chifukwa chofuna kuchimwa kapena kupanga zowonjezera. Kulaula kotentha koopsa kungathandizenso kuphatikizidwa kwa zinthu zina zadongo, monga carbides, borbides, bordes, ndi ma natrades, ndizovuta kufotokozera zakuthambo.

Zipangizo zodziwika bwino za ceramic zopangidwa ndi ma slatter ochimwa motentha:

1. Otentha amakanikizidwa boron nitride

Ufa umathiridwa mu nkhungu, kenako adakanikizidwa ndikuchichimwa kuti zipangike BOron Nitride. Imakhala ndi mafuta abwino kwambiri, kutentha kwambiri, komanso mikhalidwe yamagetsi. Ikhozanso kusunga upakati mwake ndi umunthu wake kutentha kwambiri. Ngakhale atasakanikirana ndi Boron nitride ali ndi mphamvu yotsika ndikulimbana ndi kuvala, imakhala ndi kutentha kwambiri, mphamvu zapadera, zokongoletsera zapadera, komanso zoseweretsa zazikuluzikulu, komanso zoseweretsa. Chifukwa imatha kulekerera kutentha kuposa 2000 ° mlengalenga, Boron nitride ndi kutentha kwambiri.
Ma wntrustek amagwiritsa ntchito ukadaulo wapamwamba kwambiri wopitilira muyeso kuti uwonetsetse zopanga zamagetsi, zamagetsi, zamagetsi, komanso mikhalidwe yamafuta. Timapereka katundu wopondera wa Boron, monga a CNARCIVES, ma mbale, zokongoletsedwa, ndodo, machubu, opambana, zowopsa, zotsika mtengo. Titha kuperekabe ceosumiite cerosite ceramic ceramic, kuphatikiza zrbn, snbn, albn, ndi scbn, kuphatikiza pa BN yokwera kwambiri yokwaniritsa zosowa za kasitomala.

2. Hot adakanikiza Boron Carbide B4C

Kukanikiza kotentha ndi njira yolumikizira b4C ufa wambiri mu zinthu zowiritsa, zopangidwa mwapadera pogwiritsa ntchito kukakamizidwa ndi kutentha nthawi imodzi. Kulimbikira kwambiri, malinga ndi ukadaulo wopanda unzake, kumathandizira kugwirizanitsa kwa mbewu komanso kumachepetsa kupatsa chidwi, kumapanga zigawo zina ndi mphamvu zochulukirapo komanso zabwino za neutron.

Kanthu kalikonse ka maofesi otchedwa Boron Carbide (B4C) ndikofunikira kwa madele a nyukiliya 'a neutroni. B4C imapangidwa ndi kutentha kotentha ndipo ili ndi mphamvu yosasinthika, mphamvu yabwino kwambiri, komanso kachulukidwe kamene kamakhala pafupifupi. M'malo obisalira monga magetsi, malo osungira mafuta, ndi machitidwe a zida zanyukiliya, mikhalidweyi ndi yofunikira kuti pakhale kukhulupirika komanso kutchinjiriza.

Mapulogalamu a Nyukiliya:

• Okonda zowongolera ndodo

• Kutchingira mabatani a riyakitala

• Chovala cha Neutron Neutron

• Amagwiritsa ntchito mafuta

3. Yotentha imucon nitride si3n4

SI3n4 ufa ndi zowonjezera zowonjezera (E.g. Pogwiritsa ntchito kutentha ndi kukakamizidwa mbali imodzi, njira yokhazikika yolumikizira siyi imalola kukwapula ndikuchimwa nthawi yomweyo, zomwe zitha kufulumira momwe zidanyamula zolimba ndikupanga zinthuzo.
Poyerekeza ndi si3n4 yochimwa ndi njira zachilendo, SI3n4 Ceramics imakhala ndi makhalidwe abwino, kuphatikizapo kachulukidwe kwambiri, mphamvu yayikulu, komanso nthawi yochepa.

4. Yotentha Cerium Boride Ceb6

Crium Boride ndi chinthu chodziwika bwino chomwe chimadziwika kuti Crium Hexaboride kapena Ceb6. Imakhazikika mu vacuum ndipo imakhala ndi imodzi mwa emsission yapamwamba kwambiri ya electron ndi ntchito yochepa. Zotsatira zake, Cexamu Hexaboride amagwiritsidwa ntchito kwambiri m'matumba otentha kapena capode otentha omwe adapangidwa ndi CerAbori makhiristo.
Ili ndi mawonekedwe ngati kukhazikika mu vacuum, emission emission, ndi ntchito yochepa.

5. Otentha amakanikiza lanthanum hexaboride lab6 

Lanthanum Hexaboride (lab6) ndi mankhwala ochulukirapo omwe ali ndi mawonekedwe apadera. Zinthu zofiirira zamdimazi zimakhumudwa m'madzi ndi hydrochloric acid ndipo zimakhazikika mwapadera mu madongosolo ankhanza ndi masinthidwe.
Lanthanum Boride (lab6) nthawi zambiri amapangidwa pogwiritsa ntchito kutentha kwa ochimwa, makamaka chifukwa chosinthasintha komanso luso labwino kwambiri pakutulutsa ma elekitiro.

Njira yopanga:

Kusakaniza kwapakati-ufa-kuphatikizira-cold tercing scirteing-ozizira ndi kumaliza ntchito

Ma wntrustek wamba a ceramic zinthu zomwe zimapezeka pokonzekera kutentha (HP)
