Njengoba "amazinyo embonini", i-carbide enosimende isetshenziswa kabanzi embonini yezempi, i-aerospace, ukucutshungulwa kwemishini, i-metallurgy, ukumba uwoyela, amathuluzi ezimayini, ezokuxhumana ngogesi, ezokwakha neminye imikhakha. Ngokuthuthuka kwezimboni ezansi nomfula, isidingo semakethe se-carbide enosimende siyaqhubeka nokukhula. Ngokuzayo, ukukhiqizwa kwezikhali nemishini yobuchwepheshe obuphezulu, inqubekelaphambili yesayensi nobuchwepheshe obusezingeni eliphezulu, kanye nokuthuthukiswa okusheshayo kwamandla enuzi kuzokwandisa kakhulu isidingo semikhiqizo ye-carbide enosimende enokuqukethwe kobuchwepheshe obuphezulu nokuzinza kwekhwalithi ephezulu. I-carbide enosimende ingabuye isetshenziselwe ukwenza amathuluzi okumba amatshe, amathuluzi okumba, amathuluzi okumba, amathuluzi okulinganisa, amathuluzi okugaya insimbi, ama-bearings anemba, ama-nozzles, isikhunta sehadiwe, njll.

Iyini i-carbide enosimende? I-carbide enosimende iyingxubevange eyenziwe ngezinhlanganisela eziqinile zezinsimbi eziphikisayo nezinsimbi ezibophayo ngokusebenzisa i-powder metallurgy. Kungumkhiqizo we-metallurgy oyimpushana owenziwe ngempushana engusayizi we-micron we-high-hardness refractory metal carbides (i-tungsten carbide-WC, i-titanium carbide-TiC) njengengxenye eyinhloko, i-cobalt (Co) noma i-nickel (Ni), i-molybdenum (Mo) njenge i-binder, efakwe esithandweni somlilo noma esithandweni sokunciphisa i-hydrogen. Inochungechunge lwezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokugqoka, amandla amahle nokuqina, ukumelana nokushisa, nokumelana nokugqwala. Ikakhulukazi, ubulukhuni bayo obuphezulu nokumelana nokugqoka kuhlala kungashintshile ngisho nasezingeni lokushisa elingu-500 ° C, futhi kusenobunzima obuphezulu ku-1000 ° C. Ngasikhathi sinye, ngokuthuthukiswa kobuchwepheshe bokumboza, ukumelana nokugqokwa nobulukhuni bamathuluzi e-carbide esimende kwenze ukugxuma okugqamile.

I-Tungsten iyingxenye ebalulekile yezinto zokusetshenziswa kwe-carbide enosimende, futhi ngaphezu kwe-80% ye-tungsten iyadingeka ekuhlanganiseni kwe-carbide enosimende. I-China iyizwe elinezinsiza ze-tungsten ezicebe kakhulu emhlabeni. Ngokusho kwedatha ye-USGS, izinqolobane zomhlaba ze-tungsten ore ngonyaka ka-2019 zazingaba amathani ayizigidi ezi-3.2, lapho izinqolobane ze-tungsten ore zaseChina zazingamathani ayizigidi eziyi-1.9, ezibalelwa cishe ku-60%; kunezinkampani eziningi zasekhaya ezikhiqiza i-tungsten carbide, njenge-Xiamen Tungsten Industry, i-China Tungsten High-tech, i-Jiangxi Tungsten Industry, i-Guangdong Xianglu Tungsten Industry, i-Ganzhou Zhangyuan Tungsten Industry, njll. bonke bangabakhiqizi abakhulu be-tungsten carbide, kanye nokuhlinzeka. kwanele.

I-China yizwe elikhiqiza kakhulu i-carbide enosimende emhlabeni. Ngokwezibalo ze-China Tungsten Industry Association, engxenyeni yokuqala ka-2022, amabhizinisi kazwelonke embonini ye-carbide akhiqize amathani angama-23,000 e-carbide enosimende, okuwukukhula konyaka ngo-0.2%; bathole iholo lebhizinisi elikhulu lama-yuan ayizigidi eziyizinkulungwane eziyi-18.753, okuwukukhula konyaka ngo-17.52%; futhi bathole inzuzo yama-yuan ayizigidi eziyizinkulungwane ezingu-1.648, okuwukukhula konyaka ngo-22.37%.

Izindawo ezidingekayo zemakethe ye-carbide enosimende, njengezimoto zamandla amasha, ulwazi lwe-elekthronikhi nokuxhumana, imikhumbi, ubuhlakani bokwenziwa, i-aerospace, amathuluzi omshini we-CNC, amandla amasha, isikhunta sensimbi, ukwakhiwa kwengqalasizinda, njll., zisakhula ngokushesha. Kusukela ngo-2022, ngenxa yomthelela wezinguquko esimweni samazwe ngamazwe njengokuqina kwezingxabano zesifunda, amazwe e-EU, isifunda esibalulekile sokukhiqizwa nokusetshenziswa kwe-carbide yomhlaba wonke, abone ukwanda okukhulu kwezindleko zamandla okukhiqiza i-carbide kanye nezindleko zabasebenzi. ngenxa yokukhuphuka kwentengo yamandla. I-China izoba umthwali obalulekile wokudluliswa kwemboni yayo ye-carbide enosimende.
