Isicelo se-Tungsten carbide kanye ne-Synthesis Method

Izakhiwo zomzimba kanye namakhemikhali wei-tungsten carbidei-crystalline powder emnyama emnyama.Ukuminyana okuhlobene ngu-15.6(18/4℃), indawo encibilikayo ngu-2600℃, indawo yokubilisa ingu-6000℃, ubulukhuni be-Mohs bungu-9. I-Tungsten carbide ayincibiliki emanzini, i-hydrochloric acid noma i-sulfuric acid, kodwa incibilika kungxube ye-nitric acid kanye i-hydrofluoric acid.I-Tungsten carbide ingasabela ngobudlova nge-fluorine ekamelweni lokushisa futhi ifakwe i-oxidized ku-tungsten oxide lapho ishiswa emoyeni.Ku-1550～1650℃, i-tungsten metal powder ingenziwa nge-chemistry eqondile ne-carbon black noma ku-1150 ℃, i-tungsten powder ingenziwa ngokusabela nge-carbon monoxide.

I-Application Tungsten carbide (WC) iyingxenye ebalulekile ye-chemicalbook ye-carbide enosimende nezinsimbi zensimbi, ezinobunzima obuphezulu, ukumelana nokugqoka okuphezulu kanye nokuqina okuhle kakhulu kokuphuka, okwaziwa ngokuthi "amazinyo emboni", kumathuluzi okumba, amathuluzi okusika, isikhunta esinembayo. , amathuluzi ezimayini, izinaliti zokunyathelisa, izinhlamvu zezempi zokubhoboza izikhali kanye neminye imikhakha iye yasetshenziswa kabanzi.

I-Tungsten carbide isetshenziswa emishinini yezimboni, amathuluzi okusika, ama-abrasives, izinhlamvu zokubhoboza izikhali nobucwebe.Idume kakhulu kunensimbi engagqwali ngenxa yobulukhuni bayo obumangalisayo nokumelana nokugqoka.Isetshenziselwa ukukhiqiza imikhiqizo yokugaya, kuhlanganise nokugaya nokugaya.Kuhlanganisa nokuthambekela kokuqwala izintaba, izigxobo zokushushuluza kanye nama-cleats.Ngokuyinhloko isetshenziswa ngendlela ye-carbide.
