Tlhahiso ea Tungsten Carbide Powder

Tungsten carbide powder ke thepa e tala e ka sehloohong ho hlahisa lihlahisoa tsa tungsten carbide. Lintlha tse ling li ka reka phofo ea tungsten carbide ka kotloloho, 'me tse ling li ka sebelisoa hape ho tsoa ho tse ling. Tungsten carbide phofo ha e fumanehe ka ho toba ka tlhaho. Li hlahisoa ka letoto la ts'ebetso. Sehloohong sena, tlhahiso ea tungsten carbide phofo e tla ba kenyelletso e khutšoanyane.

Tlhahiso

Tungsten carbide e na le palo e lekanang ea tungsten le carbon. Ho hlahisa tungsten carbide, tungsten trioxide e lokela ho ba hydrogenated le ho fokotseha pele. Ts'ebetsong ena, re ka fumana phofo ea tungsten le metsi a metsi. Ebe phofo ea tungsten le carbon li tla hatelloa tlas'a khatello ea ka ntle ka tekanyo e lekanang ea mole. Sebaka se hatelitsoeng se tla behoa holim'a pane ea graphite ebe se futhumatsoa ho feta 1400 ℃ ka sebōping sa induction se nang le molapo oa hydrogen. Ka ho eketseha ha mocheso, li-moles tse 2 tsa tungsten li tla itšoara ka 1mole ea carbon le ho hlahisa W2C. 'Me joale tungsten e lekanang le carbon e tla itšoara' me tungsten carbide e tla hlahisoa. Karabelo ea pele e etsahala pejana ho ea ho qetela hobane mocheso oa karabelo ea pele e tlase. Ka nako ena, ho na le W, W2C, le WC tse ngata tse teng ka seboping. Li tla itšoara tlas'a mocheso o phahameng. Kamora hore ts'ebetso e phethe, re ka fumana phofo ea tungsten carbide.

Karabelo e kholo ea lik'hemik'hale ke e latelang:

WO3 + 3H2 → W + 3H2O

2W + C = W2C

W + C = WC

Polokelo

Tungsten carbide powder e molemo ho bolokoa ka har'a sephutheloana sa vacuum le ho bolokoa ka phapusing e pholileng le e omileng.

Kopo

Tungsten carbide phofo e sebelisetsoa ho etsa lihlahisoa tsa tungsten carbide. Tungsten carbide powder, e kopantsoeng le karolo e itseng ea li-binders e tla bōptjoa ebe e tšeloa ka har'a lihlahisoa tse fapaneng tsa tungsten carbide tse tla sebelisoa lits'ebetsong tse fapaneng. Tungsten carbide powder e ka etsoa ka likonopo tsa tungsten carbide bakeng sa ts'ebeliso ea morafo, lithupa tsa tungsten carbide bakeng sa HPGR, lithupa tsa tungsten carbide bakeng sa ho etsa limmapa, le tungsten carbide burr ho seha le ho sila lisebelisoa tse ling.

Ho tsoa sehloohong sena, re ka tseba tlhahiso ea phofo ea tungsten carbide, e leng thepa e tala ea lihlahisoa tse ngata tsa tungsten carbide le li-alloys tsa tungsten. Kahoo ho boloka tungsten carbide phofo ka nepo ho bohlokoa ho netefatsa hore lihlahisoa tsa tungsten carbide li ka boloka tšebetso ea tsona.

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.
