ASTM B708 ​​e netefatsa joang hore foil ea Tantalum ea Bohloeki bo Phahameng?

Vacuum-arc le mekhoa ea ho qhibiliha ea electron-beam bakeng sa foil ea tantalum

Leeto la ho ea foil ea tantalum e hloekileng haholo le qala ka mekhoa e tsoetseng pele ea ho qhibiliha. ASTM B708 ​​e bolela mekhoa e 'meli ea mantlha ea ho hlahisa li-ingots tsa tantalum: ho qhibiliha ha vacuum-arc le ho qhibiliha ha electron-beam. Mekhoa ena e rarahaneng e thusa ho tlosa litšila le ho netefatsa bohloeki bo phahameng ka ho fetisisa ba sehlahisoa sa ho qetela.

Ho qhibiliha ha vacuum-arc ho kenyelletsa ho theha arc ea motlakase pakeng tsa eleketrode e ka sebelisoang le crucible ea koporo e pholileng ka metsi sebakeng sa vacuum. Ts'ebetso ena ka katleho e felisa litšila tse fetohang 'me e hlahisa ingot e teteaneng, e homogeneous. Sepakapaka sa vacuum se thibela tšilafalo ea likhase tsa sepakapaka, se fellang ka tantalum e hloekileng ka ho ikhethang.

Ka lehlakoreng le leng, ho qhibiliha ha elektrone-beam ho sebelisa lebone le tsepamisitsoeng la lielektrone ho qhibilihisa tantalum ka phaposing ea vacuum. Mokhoa ona o fana ka taolo e nepahetseng holim'a ts'ebetso ea ho qhibiliha 'me o lumella hore ho khethoe mouoane oa litšila tse nang le lintlha tse tlaase tse belang ho feta tantalum. Sephetho ke ingot ea ultra-pure e nang le litšila tse fokolang.

Mekhoa ena ka bobeli e bapala karolo ea bohlokoa ho fihlelleng maemo a phahameng a bohloeki a hlokoang ke ASTM B708. Tekanyetso e laela taolo e tiileng holim'a tikoloho e qhibilihang le liparamente, ho netefatsa hore li-ingots tsa tantalum tse hlahisoang li fihlela litlhoko tse thata tsa bohloeki bakeng sa lesela la tantalum Tlhahiso.

Mephato R05200 le R05400: Sebopeho le likopo

ASTM B708 ​​e hlalosa limaraka tse peli tse fapaneng tsa foil ea tantalum: R05200 le R05400. Limaraka tsena li fapana ka litlhoko tsa tsona tsa ho qaptjoa 'me li etselitsoe likopo tse itseng.

Kereiti ea R05200 ke kereiti e tloaelehileng ea foil ea tantalum, e ithorisang ka bohloeki ba bonyane ba 99.9%. Kereiti ena e loketse mefuta e mengata ea lits'ebetso, ho kenyelletsa lisebelisoa tsa ts'ebetso ea lik'hemik'hale, li-heaters tsa mocheso le li-anode tsa capacitor. Bohloeki bo phahameng ba R05200 bo netefatsa khanyetso e ntle ea kutu le ts'ebetso e tšepahalang libakeng tse hlokang.

Kereiti ya R05400, eo hape e tsejwang e le foil ya tantalum e phahameng, e isa bohlweki boemong bo latelang ka bonyane ba 99.95% ya dikahare tsa tantalum. Sehlopha sena sa Ultra-pure se etselitsoe lits'ebetso tse hlokang bohloeki le ts'ebetso e phahameng ka ho fetesisa. R05400 e fumana tšebeliso ea lisebelisoa tsa morao-rao tsa elektronike, tlhahiso ea semiconductor, le lisebelisoa tse khethehileng tsa bongaka moo esita le lits'ila tsa morao-rao li ka bang le liphello tse kholo.

ASTM B708 ​​e hlakisa ka hloko maemo a tšilafalo a lumelletsoeng bakeng sa mephato ka bobeli, e akaretsa lintho tse kang khabone, oksijene, naetrojene, haedrojene, le litšila tse fapaneng tsa tšepe. Ka ho fokotsa litšila tsena ka thata, tekanyetso e netefatsa hore foil ea tantalum e boloka thepa ea eona e ikhethang mme e sebetsa ka ts'epo lits'ebetsong tsa bohlokoa.

Khetho pakeng tsa R05200 le R05400 e itšetlehile ka litlhoko tse khethehileng tsa kopo. Leha R05200 e fana ka ts'ebetso e ntle haholo bakeng sa lits'ebeliso tse ngata, R05400 e fana ka moeli o eketsehileng oa bohloeki bakeng sa maemo a boima haholo. Tlhaloso e hlakileng ea ASTM B708 ​​ea limaraka tsena e lumella baenjiniere le bahlahisi ho khetha tse nepahetseng lesela la tantalum bakeng sa litlhoko tsa bona ka kholiseho.

Bohlokoa ba ho latela ASTM B708 ​​lits'ebetsong tsa bohloeki bo phahameng

Ho khomarela ASTM B708 ​​ke ntho ea bohlokoa ho netefatsa boleng le ho tšepahala ha foil ea tantalum bakeng sa lits'ebetso tsa bohloeki bo phahameng. Tekanyetso ena e sebetsa e le motheo oa bahlahisi, barekisi, le basebelisi ba ho qetela ka mokhoa o ts'oanang, e fana ka puo e tloaelehileng le litebello tsa tlhahiso le ts'ebetso ea tantalum foil.

E 'ngoe ea lintlha tsa bohlokoa tsa ASTM B708 ​​ke litlhoko tsa eona tsa tlhahlobo tse felletseng. Tekanyetso e laela tlhahlobo e matla ea lik'hemik'hale ho netefatsa sebopeho le bohloeki ba foil ea tantalum. Sena se kenyelletsa mekhoa e kang inductively coupled plasma mass spectrometry (ICP-MS) le glow discharge mass spectrometry (GDMS) ho bona le ho lekanya litšila tse maemong a tlase haholo.

Teko ea 'mele ke karolo e' ngoe ea bohlokoa ea ho latela ASTM B708. Tekanyetso e totobatsa litlhoko tsa matla a ho tsitsa, matla a tlhahiso, le bolelele, ho netefatsa hore foil ea tantalum e na le thepa ea mochini e hlokahalang bakeng sa lits'ebetso tse reriloeng. Ntle le moo, mamello ea boholo bo laoloa ka thata, e netefatsang botsitso le ts'epahalo lits'ebetsong tsa tlhahiso tse sebelisang foil ea tantalum.

Bakeng sa liindasteri tse itšetlehileng ka foil ea tantalum e hloekileng haholo, ho latela ASTM B708 ​​ho fana ka melemo e mengata ea bohlokoa:

• Tiisetso ea boleng: Tekanyetso e fana ka moralo o tiileng bakeng sa taolo ea boleng, ho fokotsa kotsi ea bofokoli ba thepa kapa ho se lumellane.
• Ho pheta-pheta: Ka ho khomarela ASTM B708, bahlahisi ba ka hlahisa lihlopha tse tsitsitseng tsa foil ea tantalum, ho netefatsa ts'ebetso e tšepahalang ho pholletsa le tlhahiso ea tlhahiso.
• Traceability: Tekanyetso e hloka litokomane tse qaqileng, tse lumellang hore ho be le ts'ebetso e felletseng ea lesela la tantalum ho tloha ho lihlahisoa tse tala ho ea ho sehlahisoa se felileng.
• Ntlafatso ea ts'ebetso: Litlhoko tse thata tsa bohloeki tsa ASTM B708 ​​li thusa baenjiniere ho sutumelletsa meeli ea ts'ebeliso ea foil ea tantalum, ba tseba hore ba ka itšetleha ka thepa e ikhethang ea thepa.

Lits'ebetsong tsa bohloeki bo phahameng joalo ka tlhahiso ea semiconductor, lisebelisoa tsa sefofane, le lisebelisoa tse tsoetseng pele tsa bongaka, esita le litšila tse motsotso li ka ba le litlamorao tse mpe. ASTM B708 ​​e sebetsa e le tšireletso ea bohlokoa, e netefatsang hore foil ea tantalum e kopana le litekanyetso tse hlokahalang bakeng sa mahlale ana a tsoetseng pele.

Ho feta moo, ho latela ASTM B708 ​​ho thusa khoebo le tšebelisano ea lefats'e ka har'a liindasteri tse sebelisang foil ea tantalum e hloekileng haholo. Kananelo ea machaba ea maemo a lefats'e e fana ka sebaka se tloaelehileng sa litšupiso bakeng sa barekisi le bareki lefatšeng ka bophara, ho lokisa mekhoa ea ho reka le ho khothaletsa boqapi ho pholletsa le meeli.

Ha mahlale a ntse a tsoela pele ho hatela pele le ho sutumelletsa meeli ea mahlale a lintho tse bonahalang, karolo ea ASTM B708 ​​ho netefatsa hore foil ea tantalum e hloekile e ba ea bohlokoa le ho feta. Tekanyetso e fetoha hammoho le litlhoko tsa indasteri, e kenyelletsang mekhoa e mecha ea tlhahlobo le litlhoko tsa tlhoekiso ho fihlela litlhoko tse ntseng li hola tsa lits'ebetso tse tsoetseng pele.

Qetellong, ASTM B708 ​​e eme e le bopaki ba bohlokoa ba bohlokoa ba ho emisa tlhahiso ea thepa e hloekileng haholo. Ka ho theha litlhokahalo tse matla bakeng sa ts'ebetso ea ho qhibiliha, sebopeho le tlhahlobo ea foil ea tantalum, tekanyetso ena e netefatsa hore thepa ena e makatsang e ka tsoela pele ho nts'etsapele boqapi le tsoelo-pele ho pholletsa le mefuta e mengata ea liindasteri.

Bakeng sa ba batlang foil ea boleng bo holimo ea tantalum e kopanang kapa e fetang litekanyetso tsa ASTM B708, ba se ke ba sheba hole le Baoji Freelong New Material Technology Development Co., Ltd. Joaloka moetsi ea ka sehloohong oa litšepe tse khethehileng le lialloi, re motlotlo ka ho fana ka foil ea tantalum ea premium-grade e fihlelang litlhoko tse thata ka ho fetisisa tsa liindasteri tsa theknoloji e phahameng.
