Li-Carbides tse fapaneng

Leha tungsten carbide e bapala karolo ea bohlokoa 'marakeng oa indasteri, li-carbide tse ling tse ngata li teng liindastering tse fapaneng. Sehloohong sena, o tla tseba mefuta e fapaneng ea li-carbides. Ke:

1. Boron carbide;

2. Silicon carbide;

3. Tungsten carbide;

Boron carbide

Boron carbide ke motsoako oa kristale oa boron le carbon. Ke mofuta oa thepa e entsoeng ka maiketsetso e thata haholo e le hore e ka sebelisoa haholo lihlahisoa tse chefo le tse sa senyeheng, lisebelisuoa tse kopantsoeng tse bobebe, hape li ka sebelisoa ho lithupa tsa taolo bakeng sa tlhahiso ea matla a nyutlelie.

Joaloka thepa ea indasteri, boron carbide e na le thepa e ngata. E na le boima ba Mohs ba 9 ho isa ho 10, hape ke e 'ngoe ea lisebelisoa tse thata ka ho fetisisa. Ka boima bo joalo bo phahameng le boima bo tlaase, boron carbide e ka sebelisoa e le ntho e matlafatsang bakeng sa aluminium sesoleng. Ho hanyetsa ha eona ho phahameng ho entse hore ho khonehe ho fumana lits'ebetso e le lisebelisoa tsa li-nozzles tse phatlohang le litiiso tsa pompo. Boron carbide e ka sebelisoa e le abrasive ka mokhoa o phofshoana ka har'a abrading e ntle ea lihlahisoa tsa tšepe le tsa ceramic. Leha ho le joalo, ka mocheso o tlase oa oxidation oa 400-500 ° C, boron carbide ha e khone ho mamella mocheso oa litšepe tsa ho sila tse thata.

Silicon carbide

Silicon carbide ke motsoako oa kristale oa silicon le carbon. E ile ea fumanoa ka 1891 ke moqapi oa Amerika. Ebe silicon carbide e sebelisoa e le thepa ea bohlokoa bakeng sa li-sandpaper, mabili a silang le lisebelisoa tsa ho seha. Eseng ho fihlela indasteri ea sejoale-joale ea silicon carbide e fumanoa e sebelisoa likarolong tse sa sebetseng bakeng sa lipompo esita le lienjineri tsa rocket, joalo-joalo.

Pele ho sibolloa boron carbide, silicon carbide e ne e le thepa e thata ka ho fetisisa. E boetse e na le litšobotsi tsa ho robeha, conductivity e phahameng ea mocheso, matla a mocheso o phahameng, katoloso e tlaase ea mocheso, le ho hanyetsa karabelo ea lik'hemik'hale.

Tungsten carbide

Tungsten carbide ke sesebelisoa se tsebahalang ka ho fetesisa indastering ea sejoale-joale, e nang le phofo ea tungsten carbide le phofo e itseng ea cobalt kapa nickel e le setlamo. Tungsten carbide ke ntho e teteaneng e bohlooho bo bobebe. Ho fapane ho qhibiliha ka ntlha e phahameng ea ho qhibiliha. Tungsten carbide e na le boima bo phahameng, ho hanyetsa ho roala, ho hanyetsa tšusumetso, ho hanyetsa ho tsieleha, le matla 'me e ka sebetsa nako e telele. 'Me tungsten carbide e ka etsoa ka libopeho le mefuta e sa tšoaneng ea lihlahisoa tsa tungsten carbide, tse kang li-buttons tsa tungsten carbide, li-tungsten carbide, li-tungsten carbide strips, tungsten carbide strips, tungsten carbide balls, tungsten carbide valves le tungsten carbide punch pins. Li sebelisoa haholo liindastering tsa morao-rao, tse kang merafo, khase, oli, ho itšeha, ho etsa thepa, ho laola maro, joalo-joalo.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
