Ke terata e ntle ka ho fetisisa ea ho futhumatsa element?

Ho khethoa ha terata e ntle ka ho fetisisa bakeng sa ntho ea ho futhumatsa ho itšetlehile ka litlhoko tse khethehileng tsa kopo. Leha ho le joalo, lisebelisoa tse ling tse tloaelehileng tse sebelisoang ho futhumatsa likarolo li kenyelletsa:

1. Nickel-chromium alloy: Alloy ea nickel-chromium e sebelisoa haholo linthong tse futhumatsang ka lebaka la ho hanyetsa haholo, ho hanyetsa oxidation e ntle, le ho hanyetsa mocheso o phahameng. Hangata e sebelisoa lisebelisoa tsa ntlo tse kang li-toaster, li-dryer le lionto.

2. Kanthal: Kanthal ke tšepe ea tšepe-chromium-aluminium alloy e tsejoang ka matla a eona a mocheso o phahameng, ho hanyetsa oxidation e ntle, le bophelo bo bolelele ba tšebeletso. E sebelisoa hangata lits'ebetsong tse futhumatsang tsa indasteri joalo ka li-kilns, libopi le lionto tsa indasteri.

3. Tungsten: E tsebahala ka sebaka sa eona sa ho qhibiliha se phahameng haholo, tungsten e sebelisoa lits'ebetsong tse hlokang mocheso o phahameng haholo, joalo ka libopi tsa mocheso o phahameng le lits'ebetso tse khethehileng tsa indasteri.

4. Molybdenum: Molybdenum ke ntho e 'ngoe e nang le ntlha e phahameng ea ho qhibiliha le ho hanyetsa hantle ho senya le oxidation, e leng se etsang hore e tšoanelehe bakeng sa lisebelisoa tsa mocheso o phahameng oa mocheso ka likopo tse khethehileng.

Mohala o motle ka ho fetisisa bakeng sa sesebelisoa sa ho futhumatsa o itšetlehile ka lintlha tse kang mocheso o lakatsehang oa ho sebetsa, tikoloho eo e tla sebelisoa ho eona, le litlhoko tse khethehileng tsa ho futhumatsa tsa kopo. Ntho e 'ngoe le e' ngoe e na le melemo le mefokolo ea eona, kahoo khetho e lokela ho ipapisa le litlhoko tse khethehileng tsa tšebeliso e reretsoeng ea ho futhumatsa.

Na molybdenum ke conductor e ntle ea mocheso?

Molybdenum e nkuoa e le mochini o motle oa mocheso, leha e sa tsamaise mocheso hantle joalo ka litšepe tse ling joalo ka koporo kapa aluminium. Thermal conductivity ea molybdenum mocheso oa kamore e ka bang 138 W/m·K, e ka tlaase ho koporo (hoo e ka bang 401 W/m·K) le aluminium (hoo e ka bang 237 W/m·K).

Leha ho le joalo, mocheso oa mocheso oa molybdenum o ntse o le holimo ha o bapisoa le lisebelisoa tse ling tse ngata, haholo-holo mocheso o phahameng. Sena se etsa hore molybdenum e be khetho e nepahetseng bakeng sa lits'ebetso tse hlokang ho fetisoa ha mocheso o phahameng oa mocheso, joalo ka lisebelisoa tsa ho futhumatsa, libopi tsa mocheso o phahameng le mekhoa e meng ea tsamaiso ea mocheso.

Ho phaella ho conductivity ea mocheso, molybdenum e na le lintho tse ling tsa bohlokoa tse kang sebaka se phahameng sa ho qhibiliha, ho hanyetsa oxidation, le matla a matle a mochine mocheso o phahameng, e leng se etsang hore e be lisebelisoa tse fapaneng bakeng sa mefuta e sa tšoaneng ea mocheso o phahameng.

Phekolo ea mocheso bakeng sa molybdenum ke efe?

Hangata molybdenum e phekoloa mocheso ho ntlafatsa thepa ea eona ea mochine le ho imolla khatello ea kelello ka hare. Ts'ebetso ea kalafo ea mocheso bakeng sa molybdenum hangata e kenyelletsa ho futhumatsa, mokhoa o laoloang oa ho futhumatsa le ho pholisa. Mehato e khethehileng ea kalafo ea mocheso bakeng sa molybdenum e ka kenyelletsa:

1. Anealing: Molybdenum e atisa ho kenngoa mochesong o phahameng, hangata ho tloha ho 1,800 ho isa ho 2,200 degrees Celsius (3,272 ho 3,992 degrees Fahrenheit). Boitsebiso bo tšoaroa ka mocheso ona ka nako e itseng ho lumella recrystallization le kholo ea lijo-thollo, e thusang ho imolla khatello ea kelello ka hare le ho ntlafatsa ductility.

2. Pholiso e laoloang: Ka mor'a ts'ebetso ea annealing, molybdenum e pholile butle-butle ho mocheso oa kamore ka mokhoa o laoloang ho thibela ho thehoa ha khatello e ncha ea ka hare le ho boloka microstructure e lakatsehang.

Mekhahlelo e ikhethileng ea ts'ebetso ea kalafo ea mocheso, ho kenyelletsa mocheso, nako le sekhahla sa ho pholisa, li khethoa ho ipapisitsoe le thepa e hlokahalang ea mochini le litlhoko tse ikhethileng tsa kopo.

Ka kakaretso, phekolo ea mocheso ea molybdenum e ikemiselitse ho ntlafatsa microstructure ea eona le thepa ea mochine ho netefatsa hore e loketse lisebelisoa tsa mocheso o phahameng joalo ka tlhahiso ea lisebelisoa tsa ho futhumatsa, likarolo tsa sebōpi le lisebelisoa tse ling tse khethehileng tsa indasteri.
