Mokhoa oa ho Recycle Tungsten Carbide Tools

Tungsten carbide e boetse e tsejoa e le tungsten alloy, carbide e entsoeng ka samente, alloy e thata le tšepe e thata. Lisebelisoa tsa Tungsten carbide li ntse li tsebahala haholo indastering ea sejoale-joale ho tloha ka bo-1920. Ka tikoloho, ho nchafatsoa ha lihlahisoa tsa tungsten carbide ho ka baka litšenyehelo le matla a senyehileng. Ho ka ba le mokhoa oa 'mele kapa mokhoa oa lik'hemik'hale. Mokhoa oa 'mele hangata ke ho qhaqha lisebelisoa tsa tungsten carbide tse lahliloeng likotoana, tseo ho leng thata ho li hlokomela le ho bitsa chelete e ngata ka lebaka la boima bo boholo ba lisebelisoa tsa tungsten carbide. Kahoo, lisebelisoa tsa ho seha li-tungsten carbide hangata li fumaneha ka mekhoa ea lik'hemik'hale. 'Me mekhoa e meraro ea lik'hemik'hale e tla hlahisoa---zinc recovery, electrolytic recovery, le ho ntšoa ka oxidation.

Ho tsosolosoa ha Zinc

Zinc ke mofuta oa ntho ea lik'hemik'hale e nang le nomoro ea athomo ea 30, e nang le lintlha tse qhibilihang tsa 419.5 ℃ le lintlha tse belang tsa 907 ℃. Ts'ebetsong ea ho hlaphoheloa ha zinki, lisebelisoa tsa ho seha li-tungsten carbide li kenngoa ka har'a zinki e qhibilihisitsoeng tlas'a tikoloho ea 650 ho isa ho 800 ℃ pele. Ts'ebetso ena e etsahala ka khase ea inert seboping sa motlakase. Kamora hore zinki e hlaphoheloe, zinki e tla tšeloa tlas'a mocheso oa 700 ho isa ho 950 ℃. Ka lebaka la ho hlaphoheloa ha zinki, phofo e tsosolositsoeng e batla e tšoana le phofo ea moroetsana ka tekanyo.

Electrolytic Recovery

Ts'ebetsong ena, sekontiri sa cobalt se ka qhibiliha ka ho sebelisa electrolyzing lisebelisoa tsa ho itšeha tsa tungsten carbide ho khutlisa tungsten carbide. Ka ho hlaphoheloa ha electrolytic, ho ke ke ha e-ba le tšilafalo ho tungsten carbide e tsosolositsoeng.

Ho ntšoa ka Oxidation

1. Tungsten carbide scrap e lokela ho cheka ka ho kopanngoa le li-oxidizing agents ho fumana tungsten ea sodium;

2. Sodium tungsten e ka phekoloa ka metsi le phihlelo filtration le pula ho tlosa litšila ho fumana hloekisitsoeng sodium tungsten;

3. Tungsten ea sodium e hloekisitsoeng e ka arajoa ka reagent, e ka qhibilihang ka har'a motsoako oa lintho tse phelang, ho fumana mefuta ea tungsten;

4. Eketsa tharollo ea ammonia e nang le metsi a metsi ebe o ntša hape, re ka fumana tharollo ea ammonium poly-tungstate;

5. Ho bonolo ho fumana kristale ea ammonium para-tungstate ka ho evaporating tharollo ea ammonium poly-tungstate;

6. Ammonium para-tungstate e ka calcined ebe e fokotsoa ke hydrogen ho fumana tšepe ea tungsten;

7. Ka mor'a ho pata tšepe ea tungsten, re ka fumana tungsten carbide, e ka etsoang ka lihlahisoa tse fapaneng tsa tungsten carbide.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
