Sebaka sa ts'ebeliso ea tungsten

Tungsten e tsejoang hape e le wolfram, ke ntho ea lik'hemik'hale e nang le letšoao la W le nomoro ea athomo ke 74. Ke tšepe e ikhethang e nang le mefuta e mengata ea tšebeliso ea theknoloji ea morao-rao. Tungsten tšepe ke tšepe e thata le e sa tloaelehang. E ka fumanoa feela lefatšeng ka metsoako ea lik'hemik'hale. Boholo ba metsoako ea eona ea lik'hemik'hale ke tungsten oxide 'me boholo ba merafo ea tungsten e fumanoe Chaena. Haholo-holo liprofinseng tsa Hunan le Jiangxi. Ka lebaka la boemo ba eona bo phahameng ba ho qhibiliha, boima bo phahameng, khanyetso e ntle ea kutu, tsamaiso e ntle ea motlakase, le conductivity ea mocheso, e fetohile e 'ngoe ea lisebelisoa tsa bohlokoa ka ho fetisisa tse sebetsang indastering ea kajeno. E sebelisoa haholo ho alloy, elektroniki, lik'hemik'hale, bongaka le mafapha a mang.

1. Lefapheng la li-alloys tsa Industrial

Metallurgy ea phofo ke mokhoa oa ho hlahisa lihlahisoa tsa tungsten sintered. Tungsten phofo ke thepa e tala ea bohlokoa ka ho fetisisa le sebaka sa ho qala sa lihlahisoa tsa liminerale tsa tungsten. Tungsten phofo e entsoe ka ho besoa le ho futhumatsa tungsten oxide moeeng oa hydrogen. Bohloeki, oksijene le boholo ba likaroloana li bohlokoa haholo bakeng sa ho lokisa phofo ea tungsten. E ka kopanngoa le lisebelisoa tse ling ho etsa li-alloys tse fapaneng tsa tungsten.

Carbide e entsoeng ka samente e thehiloeng ho Tungsten carbide:

Tungsten carbide hangata e sebelisoa ho kopanya le litšepe tse ling ho ntlafatsa ts'ebetso ea eona. Metsoako ea tšepe e kenyelletsa cobalt, titanium, tšepe, silevera le tantalum. Sephetho ke hore tungsten carbide-based cemented carbide e na le khanyetso e phahameng ea ho apara le thepa e phahameng ea refractory. Li sebelisoa haholo-holo ha ho etsoa lithulusi tsa ho itšeha, lisebelisoa tsa merafo, ho taka terata, joalo-joalo. Lihlahisoa tsa carbide tse entsoeng ka samente tse thehiloeng ho Tungsten li ratoa esita le ho feta tšepe e sa hloekang ka lebaka la ho thatafala ha tsona le ho hanyetsa ho senyeha ha tsona. E ka sebelisoa haholo lits'ebetsong tsa kaho ea khoebo, lisebelisoa tsa elektroniki, ho etsa lisebelisoa tsa indasteri, lisebelisoa tse sireletsang mahlaseli a kotsi, le indasteri ea sefofane.

Alloy e thibelang mocheso le ho sebetsa:

Sebaka se qhibilihang sa tungsten ke sona se phahameng ka ho fetisisa har'a litšepe tsohle, 'me boima ba eona ke ba bobeli ho feta daemane. Ka hona, hangata e sebelisoa ho hlahisa li-alloys tse thibelang mocheso le ho apara. Mohlala, li-alloys tsa tungsten le litšepe tse ling tse refractory (tantalum, molybdenum, hafnium) hangata li hlahisoa likarolo tse matla joalo ka li-nozzles le lienjine tsa lirokete. 'Me li-alloys tsa tungsten, chromium, le carbon li atisa ho sebelisoa ho hlahisa likarolo tse matla le tse sa senyeheng, tse kang li-valve tsa lienjene tsa lifofane, mabili a turbine, joalo-joalo.

2. Lefapheng la lik'hemik'hale

Metsoako ea tungsten hangata e sebelisoa ho hlahisa mefuta e itseng ea lipente, li-inks, litlolo le lintho tse etsang hore motho a khone ho etsa lintho tse etsang hore a be le lintho tse etsang hore a be le lintho tse ngata tse etsang hore a be le lintho tse ngata tse etsang hore motho a be le lintho tse ngata tse khathollang. Ka mohlala, tungsten oxide e ’mala oa boronse e sebelisoa ha ho penta, ’me hangata ho sebelisoa calcium kapa magnesium tungsten ho etsa phosphors.

3. Lefapheng la sesole

Lihlahisoa tsa Tungsten li 'nile tsa sebelisoa ho nkela lisebelisoa tsa uranium sebakeng sa loto le tse senyehileng ho etsa lihlooho tsa ntoa ka lebaka la thepa ea tsona e se nang chefo le tšireletso ea tikoloho, e le ho fokotsa tšilafalo ea thepa ea sesole tikolohong ea tikoloho. Ho phaella moo, tungsten e ka etsa hore ts'ebetso ea ntoa ea lihlahisoa tsa sesole e phahame ka lebaka la boima ba eona bo matla le khanyetso e ntle ea mocheso o phahameng.

Tungsten e ka sebelisoa eseng feela libakeng tse ka holimo empa hape le ho tsamaisa, matla a athomo, kaho ea likepe, indasteri ea likoloi le mafapheng a mang. Haeba u thahasella tungsten kapa u na le lipotso ka eona. Ka kopo ikopanye le rona hona joale.
