Tungsten foil - se e le moo e sebediswa?

Ka lebaka la buka e ikhethang thepa ea lona ea foil tungsten ho atile. E sebelisoa likarolong tse ngata tsa bophelo, ho tloha moriana le ho ipolaea le boenjiniere bo, matla a nyutlelie.

thepa

Ho sa tsotellehe ho botenya nyenyane (ea 0.03-0.09 limilimithara), tungsten foil nang le tsona litšobotsi tse makatse:

• Mocheso ho hanyetsa le mocheso ho hanyetsa. Long bophelo tšebeletso, esita le ka mocheso ho fihlela ho likhato 2500.

• Phahameng compression (tjaleho) karo-karolelano.

• A boleng kgolo ya ho hanyetsa motlakase.

• tlaase haholo mogote tjaleho coefficient.

• Phahameng mocheso kenelle hanyetsa boleng.

• Matla.

• A phahameng lintlha elektrone mohlapo.

• Ha corrode.

• Manganga ho lik'hemik'hale (acid, alkalis, Aqua regia).

• Biologically sireletsehileng.

• E lumelloa ho sebelisa ka libakeng senyang phahameng mocheso le mejaro e phahameng.

Hammoho le melemo e mengata ea lintho tse bonahalang tse o boetse o na go tlhoka mesola lona:

• E hloekileng tungsten ke ho le thata ho fumana, kaha ke ka seoelo haholo.

• The phahameng itseng matla a khoheli.

• Ha thempereichara e tlaase, lintho tse bonahalang tse tla ba brittle.

• Tungsten - capricious mme refractory lihlahisoa tse tala, eo ho leng thata ho sebetsa.

• Production ke khoneha feela ka tlas'a futhumatsang matla ea lihlahisoa tse tala.

Ka lebaka refractoriness, khaello ea lihlahisoa tse tala, mathata ka tsela ea kalafo ea hae ea theko ea lihlahisoa tsa o qetile e phahameng.

ho hlahisoeng

Tungsten foils entsoe ka tšepe e hloekileng. Maqephe a etsoa ka phehella ka a shoa lokisitseng. Ka mor'a moo, tšepe e halefile le theha ka mocheso oa likhato 1500-1700.

Ho sireletsa khahlanong le ho kena moea sebelisa tšepe ntse e chesang sarolohang ka phahameng lebelo. Ha lakane bokima fihla tse 0.6 limilimithara, lebelo sarolohang e fokotsehile. Ho fetisisa maqephe tšesaane fumanoa ka batang sarolohang. Ho holim foil ke le boreleli, sebelisa li matha-in.

Ho tlosa litsila tse teng ho kena moea sebetsa halefile sodium tharollo. Ka mor'a moo, lakane e ile calcined ka ho ba teng ha haedrojene ka mocheso oa likhato tse 1000.

lekala la kopo

Sebetsa foil tungsten (VA ya 0.05 limilimithara ho akarelletsa) libakeng tse ngata. Ka sehloohong har'a bona ke tsena:

• Mechanical boenjiniere.

• Lifofane.

• matla a nyutlelie.

• Indasteri ea oli.

• Lik'hemik'hale indasteri.

• Radiotehnka.

• Motlakase boenjiniere.

• Moriana.

Tungsten foil ka lebaka la ho thepa ea eona e ikhethang e sebediswa e le lithebe mocheso, ea boemo ba leholimo e entsoeng warmers le thepa mocheso phapanyetsano.
