Mokhoa oa ho sebelisa Tungsten Carbide

Tungsten carbide (WC) ke motsoako oa lik'hemik'hale oa tungsten le carbon ka tekanyo ea stoichiometric ea 93.87% tungsten le 6.13% carbon. Leha ho le joalo, indastering lentsoe lena hangata le bolela tungsten carbides e entsoeng ka samente; sehlahisoa sa metallurgical se entsoeng ka sintered se entsoeng ka lithollo tse ntle haholo tsa tungsten carbide e hloekileng e tlanngoeng kapa e kopantsoeng hammoho ka har'a matrix ea cobalt. Boholo ba lithollo tsa tungsten carbide bo tloha ho ½ ho isa ho 10 microns. Likahare tsa cobalt li ka fapana ho tloha ho 3 ho isa ho 30%, empa hangata li tla tloha ho 5 ho isa ho 14%. Boholo ba lijo-thollo le litaba tsa cobalt li etsa qeto ea tšebeliso kapa tšebeliso ea ho qetela ea sehlahisoa se felileng.

Carbide e entsoeng ka samente ke e 'ngoe ea litšepe tsa bohlokoahali, lihlahisoa tsa tungsten carbide tse sebelisoang haholo ho etsa lisebelisoa tsa ho itšeha le ho etsa lisebelisoa, liboro, li-abrasives, likotoana tsa majoe, li-dies, rolls, ornance le lisebelisoa tsa ho roala holim'a metsi. Tungsten carbide e bapala karolo ea bohlokoa ntlafatsong ea indasteri. Kaofela rea ​​tseba hore tungsten ke mofuta oa thepa e ke keng ea nchafatsoa. Litšobotsi tsena li etsa hore tungsten carbide scrap e be e 'ngoe ea litlholisano tse ntle ka ho fetisisa tsa ho e sebelisa hape.

Tsela ea ho tsosolosa tungsten ho tloha tungsten carbide? Ho na le mekhoa e meraro Chaena.

Hajoale, ho na le mefuta e meraro ea ts'ebetso ea carbide e entsoeng ka samente le ts'ebetso ea ho nchafatsa e sebelisoang haholo lefatšeng, ke mokhoa oa ho qhibiliha oa zinki, mokhoa oa ho qhibiliha ha elektronike, le mokhoa oa ho phunya ka mochini.

1. Mokhoa oa ho qhibilihisa zinki:

Mokhoa oa ho qhibilihisa zinki ke ho eketsa zinki mochesong oa 900 ° C ho etsa motsoako oa zinki-cobalt pakeng tsa cobalt le zinki ka har'a litšila tse samenteng carbide. Mocheso o itseng oa mocheso, zinki e ntšoa ka vacuum distillation ho etsa motsoako o kang oa seponche ebe oa siloa, oa hlongoa le ho siloa hore e be phofo e tala. Qetellong, lihlahisoa tsa carbide tse entsoeng ka samente li lokiselitsoe ho latela mokhoa o tloaelehileng. Leha ho le joalo, mokhoa ona o na le lisebelisoa tse kholo tsa thepa, litšenyehelo tse phahameng tsa tlhahiso, le tšebeliso ea matla, 'me ho thata ho tlosa zinki ka ho feletseng, ho fella ka boleng bo sa tsitsang ba sehlahisoa (ts'ebetso). Ho feta moo, zinki e sebelisoang e le dispersant e kotsi 'meleng oa motho. Ho boetse ho na le bothata ba tšilafalo ea tikoloho ho sebelisoa mokhoa ona.

2. Mokhoa oa ho qhala:

Mokhoa oa ho qhibiliha ka motlakase ke ho sebelisa sesebelisoa se loketseng sa leaching ho qhaqha "cobalt" ea tšepe ka har'a litšila tse entsoeng ka carbide ka har'a tharollo ea leaching tlas'a ts'ebetso ea ts'ebetso ea motlakase ebe o e sebelisa ka lik'hemik'hale hore e be phofo ea cobalt, e tla qhibiliha. Li-blocks tsa scrap alloy tsa binder lia hloekisoa.

Ka mor'a ho sila le ho sila, phofo ea tungsten carbide e fumanoa, 'me qetellong, sehlahisoa se secha sa carbide se entsoeng ka samente se etsoa ho latela mokhoa o tloaelehileng. Le hoja mokhoa ona o na le litšobotsi tsa boleng bo botle ba phofo le lintho tse fokolang tse sa hloekang, o na le bofokoli ba ho phalla ha nako e telele, lisebelisoa tse rarahaneng tsa electrolysis, le ts'ebetso e fokolang ea litšila tsa tungsten-cobalt tse entsoeng ka carbide e nang le cobalt e kholo ho feta 8%.

3. Mokhoa oa setso oa ho silakanya mochini:

Mokhoa oa setso oa ho phunya mochini ke motsoako oa ho phunya ka letsoho le ka mochini, 'me carbide e entsoeng ka samente e kentsoeng ka letsoho e kentsoe leboteng le kahare ka poleiti e entsoeng ka samente ea carbide le mochini o silafatsang o nang le libolo tsa samente tse boholo bo boholo. E pshatleha hore e be phofo ka ho sisinyeha le ho (rola), ebe mobu o kolobileng o fetoha motsoako, 'me qetellong o etsoa lihlahisoa tsa carbide tse entsoeng ka samente ho ea ka mokhoa o tloaelehileng. Mofuta ona oa mokhoa o hlalosoa sehloohong se reng "Recycling, Regeneration, and Utilization of Waste Cemented Carbide". Le hoja mokhoa ona o na le melemo ea ts'ebetso e khutšoanyane le lichelete tse fokolang tsa thepa, ho bonolo ho kopanya litšila tse ling ka thepa, 'me litaba tsa oksijene tsa thepa e tsoakiloeng li phahame, tse nang le tšusumetso e tebileng ho boleng ba lihlahisoa tsa alloy,' ha e khone ho finyella litlhoko tsa litekanyetso tsa tlhahiso, 'me esale e le Ho phaella moo, katleho ea ho senya e tlaase haholo,' me ka kakaretso e nka lihora tse ka bang 500 tsa ho roala le ho sila, 'me hangata ho thata ho finyella botle bo hlokahalang. Ka hona, mokhoa oa phekolo ea tsosoloso ha o e-s'o atolosoe le ho sebelisoa.

Haeba u batla ho tseba haholoanyane ka ho phatloha ha abrasive, amohela ho ikopanya le rona bakeng sa lintlha tse lingion.
