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

Khetho ea terata e ntle ka ho fetisisa bakeng sa ntho ea ho futhumatsa e 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 tsa ho futhumatsa liindasteri tse kang 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 motlakase 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.
