Tlhahiso ea Sehlahisoa
Joaloka tšepe e se nang ferrous, tungsten e na le matla a phahameng haholo le boima.Ka lebaka la likarolo tsena tsa 2.Main, tungsten carbide e nang le boima bo phahameng le ho hanyetsa ho apara ka matla ho sebelisitsoe lisebelisoa tsa ho itšeha le lisebelisoa tsa merafo ka tekanyo e kholo.
Tungsten ke tšepe e refractory e nang le ntlha e phahameng ka ho fetisisa ea ho qhibiliha.Limetale tse akaretsang tse nang le ntlha e qhibidihang ho feta 1650 ℃ le sebaka se itseng sa polokelo le sebaka se qhibidihang ho feta sebaka se qhibidihang sa zirconium (1852 ℃) se bitswa dimetale tse refractory.Litšepe tse tloaelehileng tse refractory ke tungsten, tantalum, molybdenum, niobium, hafnium, chromium, vanadium, zirconium le titanium.E le tšepe e refractory, molemo oa bohlokoa ka ho fetisisa oa tungsten ke hore e na le matla a matle a mocheso o phahameng le ho hanyetsa ho hotle ha kutu ho litšepe tse qhibilihisitsoeng tsa alkali le mouoane.E hlaha feela ka holimo ho 1000 ℃.Molybdenum le tungsten li na le thepa e ts'oanang haholo, sebaka se belang se hlahelletseng le motlakase oa motlakase, li-coefficient tse nyane tsa mela ea ho futhumatsa mocheso, 'me ho bonolo ho sebetsa ho feta tungsten.
Thermal conductivity ea tšepe ea molybdenum [135 watts / (m · open)] e sebetsa hantle ka mocheso o itseng [0.276 kJ / (kg · bula)], e leng se etsang hore e be khetho ea tlhaho khahlanong le ho tsosoa ha mocheso le mokhathala oa mocheso.Sebaka sa ho qhibiliha ha eona ke 2620 ℃, ea bobeli ho tungsten le tantalum, empa boima ba eona bo tlase haholo, kahoo matla a eona a khethehileng (matla / density) a maholo ho feta tungsten, tantalum le lisebelisoa tse ling, tse sebetsang haholoanyane lits'ebetsong tse nang le litlhoko tse boima tsa boima.Molybdenum e ntse e na le matla a holimo ho 1,200 ℃.
Likarolo tse ka Sehloohong
Tungsten e na le ntlha e phahameng ea ho qhibiliha, khatello ea mouoane e tlase haholo, le sekhahla se senyenyane sa mouoane.Thepa ea lik'hemik'hale ea tungsten e tsitsitse haholo, ha e sebetse ka moea le metsi ka mocheso oa kamore, e ke keng ea qhibiliha ka hydrochloric acid, sulfuric acid, nitric acid le alkali solution.Qhibiliha ka metsing a borena le motsoako oa nitric acid le hydrofluoric acid.Ka mocheso o phahameng, o ka kopana le chlorine, bromine, iodine, carbon, nitrogen, sulfur, empa eseng ka hydrogenation.Sebaka se qhibilihang sa tungsten se fihla ho 3410 ℃, se ntseng se e-na le matla a holimo hoo e ka bang 1300 ℃, athe alloy e thehiloeng ho tungsten le eona e na le matla a holimo hoo e ka bang 1800 ℃ 'me e na le khanyetso e ntle ea mocheso.
Sesebelisoa sa Sehlahisoa
Ka lebaka la matla a phahameng a tungsten, boima bo phahameng, ka hona, e fetohile lisebelisoa tse loketseng ho etsa li-alloys tse phahameng tsa matla a khoheli, Lisebelisoa tsena tse phahameng tsa matla a khoheli li arotsoe ka W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag le lihlooho tse ling tse kholo, mofuta ona oa motsoako o na le2.Main Featuress ea karo-karolelano e phahameng, matla a phahameng, matla a matla a ho monya mahlaseli, conductivity e kholo ea mocheso, coefficient e nyane ea katoloso ea mocheso, conductivity e ntle ea motlakase, weldability le processability e ntle, E sebelisoa haholo sebakeng sa sefofane, sefofane, sesole, ho cheka oli, lisebelisoa tsa motlakase, meriana le tse ling. liindasteri, joalo ka ho etsa lihlomo, sinki ea mocheso, hamore ea ho laola lets'oao le lisebelisoa tsa ho ikopanya tse kang sesebelisoa sa thipa, sekhechana sa potoloho, li-electrode tsa welding, jj.
Sebaka sa elektronike
Tungsten e na le polasetiki e matla, lebelo le lenyenyane la mouoane, sebaka se phahameng sa ho qhibiliha le bokhoni bo matla ba ho ntša elektrone, kahoo tungsten le li-alloys tsa eona li sebelisoa haholo indastering ea phepelo ea motlakase le motlakase.Mohlala, terata ea tungsten e na le lebelo le khanyang le bophelo bo bolelele ba ts'ebeletso, ka hona e sebelisoa haholo ha ho etsoa li-bulb filament tse fapaneng, joalo ka lebone la incandescent, lebone la iodine ea tungsten, terata ea tungsten le eona e ka sebelisoa ho etsa cathode e chesang e otlolohileng. heke ea elektronike oscillator tube le mefuta e fapaneng ya liletsa tsa elektronike ka lehlakoreng thermal cathode hitara.The2.Main Featuress ea tungsten etsa hore e boetse e loketse bakeng sa TIG tjheseletsa le lisebelisoa tse ling eleketrode bakeng sa mosebetsi o tšoanang.
Indasteri ea lik'hemik'hale
Metsoako ea Tungsten e sebelisoa hangata e le li-catalysts le mebala e sa bonahaleng, joalo ka tungsten disulfide e sebelisoa joalo ka setlolo le catalyst ho peterole ea maiketsetso, bronze tungsten oxide e sebelisoa litšoantšong, calcium kapa magnesium tungsten hangata e sebelisoa ho phosphors.
Libaka tse ling
Hobane tungsten e tšoana le khalase ea boryl silicate, e sebelisetsoa ho etsa litiiso tsa khalase kapa tsa tšepe.Tungsten e na le kutlo e tlase mme e sebelisetsoa ho etsa mabenyane a khauta a tungsten a hloekileng.Ho feta moo, tungsten e boetse e sebelisoa meriana ea mahlaseli, 'me lisebelisoa tse ling li tla sebelisa terata ea tungsten.
