Ukuveliswa kweTungsten Carbide Powder

I-tungsten carbide powder yeyona nto iphambili ekuveliseni iimveliso ze-tungsten carbide. Ezinye izinto zinokuthenga i-tungsten carbide powder ngokuthe ngqo, kwaye ezinye zinokuphinda zisetyenziswe kwabanye. I-tungsten carbide powder ayifumaneki ngokuthe ngqo kwindalo. Ziveliswa ngoluhlu lwenkqubo. Kule nqaku, ukuveliswa kwe-tungsten carbide powder kuya kuba sisingeniso esifutshane.

Imveliso

I-tungsten carbide iqulethe inani elilinganayo le-tungsten kunye nekhabhoni. Ukuvelisa i-tungsten carbide, i-tungsten trioxide kufuneka ibe yi-hydrogenated kwaye iyancipha kuqala. Kule nkqubo, sinokufumana umgubo we-tungsten kunye namanzi angamanzi. Emva koko i-tungsten powder kunye nekhabhoni iya kucinezelwa phantsi koxinzelelo lwangaphandle kwi-mole ratio elinganayo. Ibhloko ecinezelweyo iya kufakwa kwipani yegraphite kwaye ifudunyezwe ukuya ngaphezulu kwe-1400 ℃ kwisithando somlilo esine-hydrogen stream. Ngokunyuka kweqondo lokushisa, i-2 moles ye-tungsten iya kusabela kunye ne-1mole yekhabhoni kwaye ivelise i-W2C. Kwaye ke i-tungsten elinganayo kunye nekhabhoni iya kusabela kwaye i-tungsten carbide iya kuveliswa. Indlela yokusabela yangaphambili yenzeke ngaphambi kwexesha kuneyamva kuba iqondo lobushushu lempendulo yangaphambili lisezantsi. Okwangoku, kukho i-W, i-W2C, kunye ne-WC eninzi ekhoyo kwiziko. Ziya kusabela phantsi kwamaqondo obushushu aphezulu. Emva kokuba inkqubo igqityiwe, sinokufumana i-tungsten carbide powder.

Eyona ndlela yokusabela kwikhemikhali yile ilandelayo:

WO3 + 3H2 → W + 3H2O

2W + C = W2C

W + C = WC

Ugcino

I-tungsten carbide powder ingcono igcinwe kwi-vacuum packing kwaye igcinwe kwigumbi elipholileyo nelomileyo.

Isicelo

I-tungsten carbide powder isetyenziselwa ukuveliswa kweemveliso ze-tungsten carbide. I-tungsten carbide powder, exutywe kunye nomlinganiselo othile wezibophelelo ziya kubunjwa kwaye zifakwe kwiimveliso ezahlukeneyo ze-tungsten carbide eziza kusetyenziswa kwizicelo ezahlukeneyo. I-tungsten carbide powder inokwenziwa ibe ngamaqhosha e-tungsten carbide ukuze asetyenziswe kwimigodi, ii-tungsten carbide studs ze-HPGR, ii-tungsten carbide rods zokuvelisa ii-end Mills, kunye ne-tungsten carbide burr yokusika kunye nokugawula ezinye izixhobo.

Ukususela kweli nqaku, siyakwazi ukuveliswa kwe-tungsten carbide powder, eyona nto inqabileyo yezinto ezininzi ze-tungsten carbide kunye ne-tungsten alloys. Ke ukugcina i-tungsten carbide powder ngokufanelekileyo kubalulekile ukuqinisekisa ukuba iimveliso ze-tungsten carbide zinokugcina ukusebenza kwazo.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
