Izakhiwo zamakhemikhali ze-tungsten carbide

I-Tungsten carbide (WC) iwuhlobo lwe-alloy eqinile, eyakhiwe ngekhabhoni nezakhi ze-tungsten kuhlanganiswe ngokuqinile.Amakhemikhali ayo azinzile, futhi akulula ukusabela ngomoya, i-asidi, i-alkali nokunye ekamelweni lokushisa.Ngaphezu kwalokho, i-tungsten carbide nayo inephuzu eliphakeme lokuncibilika nobulukhuni, obuvumela ukuthi igcine ukusebenza okuhle kakhulu ekushiseni okuphezulu nasezindaweni ezicindezelayo.

Izakhiwo ezingokomzimba ze-tungsten carbide

Izici ezibonakalayo ze-tungsten carbide zifaka phakathi ukuminyana, ubulukhuni, ukuguquguquka kokushisa, njll. Ukuminyana kwayo kucishe kube ngu-15.6g/cm³, futhi ukuqina kungokwesibili kuphela kwedayimane, kufika ku-2800-3500MPa.Ngaphezu kwalokho, i-tungsten carbide ibuye ibe nokuhamba kahle kwe-thermal kanye nokufakwa kukagesi, ukuze isetshenziswe kabanzi emazingeni okushisa aphezulu kanye nezinto zikagesi eziphezulu, ama-semiconductors neminye imikhakha.

Indlela yokulungiselela i-tungsten carbide

Izindlela eziyinhloko zokulungiselela i-tungsten carbide yindlela ye-electrochemical, indlela yokunciphisa nokunye.Indlela ye-Electrochemical iwukusebenzisa i-electrolysis ye-tungsten yensimbi ne-carbon, ukuze iphendule ngaphansi kwezimo ezithile ukukhiqiza i-tungsten carbide.Umgomo wokunciphisa uwukusabela i-WO-₃ nge-carbon emnyama ezingeni lokushisa eliphezulu ukuze kwakhiwe i-tungsten carbide.Lezi zindlela zingafinyelela ukukhiqizwa okukhulu ukuze kuhlangatshezwane nezidingo zemboni.

Inkambu yesicelo se-Tungsten carbide

I-Tungsten carbide inezinhlobonhlobo zezicelo, okuhlanganisa i-electronics, izindiza, izimoto nokunye.Emkhakheni we-electronics, i-tungsten carbide isetshenziswa njengamathuluzi okusika i-carbide, amathuluzi okusika, njll., ukuthuthukisa ukusebenza kahle kokucubungula.Emkhakheni wezindiza, i-tungsten carbide ingasetshenziswa ukwenza izingxenye zenjini yendiza, izingxenye zesakhiwo sezindiza, njll., ukuthuthukisa izinga lokushisa eliphezulu nokumelana nokugqoka.Emkhakheni wezimoto, i-tungsten carbide isetshenziselwa ukwenza izingxenye zenjini, amagiya, njll., ukuthuthukisa ukumelana nokuguga nokumelana nokugqwala.

Izinzuzo ze-tungsten carbide

Izinzuzo ze-tungsten carbide ziboniswa ikakhulukazi kulezi zici ezilandelayo:

1. Ukumelana nokugqwala kokushisa okuphezulu: I-Tungsten carbide isengakwazi ukugcina izakhiwo zamakhemikhali ezinzile ngaphansi kwemvelo yokushisa okuphezulu, futhi akulula ukuba i-oxidized futhi igqwale.

2. Ukumelana ne-oxidation: I-Tungsten carbide akulula ukuyikhipha ekushiseni okuphezulu, futhi ingamelana ngokuphumelelayo nokuguguleka kwe-oxidation.

3. Amandla aphezulu nobulukhuni: I-Tungsten carbide inobunzima obuphezulu namandla, ingamelana nokucindezeleka okuphezulu kanye nemvelo ephezulu yomthwalo.

4. Ukumelana nokugqokwa okuhle: I-Tungsten carbide inokumelana okuhle nokugqokwa futhi ingamelana ngokuphumelelayo nokungqubuzana nokugqoka.

Ukungalungi kwe-tungsten carbide

Nakuba i-tungsten carbide inezinzuzo eziningi, futhi inezinye izinto ezimbi.Okokuqala, ukucubungula kwe-tungsten carbide kunzima futhi kudinga imishini ekhethekile nezinqubo.Okwesibili, intengo ye-tungsten carbide iphakeme kakhulu, ekhawulela ukusetshenziswa kwayo kwezinye izinkambu.Ngaphezu kwalokho, ukumelana nomthelela we-tungsten carbide akubi, kuntekenteke, kudinga ukunaka.

Umkhuba wokuthuthukiswa kwesikhathi esizayo we-tungsten carbide

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, i-tungsten carbide inamandla amakhulu okuthuthukiswa esikhathini esizayo.Okokuqala, izinhlobo ezintsha zezinto ze-tungsten carbide zihlale zithuthukiswa, njenge-nano tungsten carbide, i-composite tungsten carbide, njll., ezinokusebenza okungcono kanye nohlu olubanzi lwezinhlelo zokusebenza.Okwesibili, izindlela ezintsha zokulungiselela nobuchwepheshe nazo ziyavela, njengokufakwa komhwamuko wamakhemikhali, ukuthuthukiswa kwe-plasma, njll., okungalungisa izinto ezisezingeni eliphezulu ze-tungsten carbide ngempumelelo.

Indlela yokusebenzisa i-tungsten carbide ngokunengqondo

Ukuze sisebenzise i-tungsten carbide ngokunengqondo, kufanele siqale siqonde izakhiwo nezici zayo, futhi sikhethe okulungile kwe-tungsten carbide ngokwezidingo ezahlukahlukene zohlelo lokusebenza.Okwesibili, kufanele sinake ukukhethwa kobuchwepheshe bokucubungula, sigweme ukucubungula ngokweqile kanye nokwelashwa okushisa okuphezulu, ukuze kugcinwe ukusebenza nokuzinza kwe-tungsten carbide.Ngaphezu kwalokho, kufanele sinake ukuvikelwa kwemvelo kanye nezindaba zokuphepha, futhi sinciphise ukuphehlwa kukadoti nomthelela emvelweni ngangokunokwenzeka.

Ngamafuphi, i-tungsten carbide iyinto enokusetshenziswa okubanzi namandla okuthuthuka kwesikhathi esizayo, futhi amathemba okusebenza kwayo emikhakheni ehlukahlukene abanzi.Ngocwaningo oluqhubekayo kanye nokusungula izinto ezintsha, siyaqiniseka ukuthi sizosebenzisa kangcono le nto enhle kakhulu esikhathini esizayo futhi sibambe iqhaza ekuthuthukisweni komphakathi wesintu.
