Ukukhiqizwa kwe-Tungsten Carbide Powder

I-Tungsten carbide powder iyisisetshenziswa esiyinhloko sokukhiqiza imikhiqizo ye-tungsten carbide. Ezinye izici zingase zithenge i-tungsten carbide powder ngokuqondile, kanti ezinye zingase ziphinde zisetshenziswe kwabanye. I-tungsten carbide powder ayitholakali ngokuqondile emvelweni. Akhiqizwa uchungechunge lwenqubo. Kulesi sihloko, ukukhiqizwa kwe-tungsten carbide powder kuzoba isingeniso esifushane.

Ukukhiqiza

I-Tungsten carbide iqukethe inani elilinganayo le-tungsten ne-carbon. Ukukhiqiza i-tungsten carbide, i-tungsten trioxide kufanele ifakwe i-hydrogenated futhi incishiswe kuqala. Kule nqubo, singathola i-tungsten powder namanzi awuketshezi. Khona-ke i-tungsten powder kanye nekhabhoni izocindezelwa ngaphansi kwengcindezi yangaphandle ngesilinganiso esilinganayo imvukuzane. Ibhulokhi elicindezelweyo lizofakwa epanini legraphite futhi lishisiswe libe ngaphezu kuka-1400℃ esithandweni sokungeniswa esinomfudlana we-hydrogen. Ngokukhuphuka kwezinga lokushisa, ama-moles angu-2 e-tungsten azosabela nge-1mole ye-carbon futhi akhiqize i-W2C. Futhi-ke i-tungsten elinganayo ne-carbon izosabela futhi i-tungsten carbide izokhiqizwa. Ukusabela kwangaphambili kwenzeka ngaphambi kwalokhu kwakamuva ngoba izinga lokushisa lokusabela kwangaphambili liphansi. Njengamanje, kukhona i-W, W2C, kanye ne-WC eningi ekhona esithandweni. Zizosabela ngaphansi kwamazinga okushisa aphezulu. Ngemuva kokuthi inqubo isiqediwe, singathola i-tungsten carbide powder.

Ukusabela kwamakhemikhali okuyinhloko imi kanje:

WO3 + 3H2 → W + 3H2O

2W + C = W2C

W + C = WC

Isitoreji

I-tungsten carbide powder ingcono igcinwe ku-vacuum packing futhi igcinwe ekamelweni elipholile nelomile.

Isicelo

I-Tungsten carbide powder isetshenziselwa ukukhiqizwa kwemikhiqizo ye-tungsten carbide. I-tungsten carbide powder, exutshwe nengxenye ethile yezibophezelo izololongwa futhi ifakwe emikhiqizweni ehlukene ye-tungsten carbide ezosetshenziswa ezisetshenziswa ezahlukene. I-Tungsten carbide powder ingenziwa ibe izinkinobho ze-tungsten carbide ukuze zisetshenziswe ezimayini, izikhonkwane ze-tungsten carbide ze-HPGR, izinti ze-tungsten carbide zokukhiqiza izigayo zokugcina, kanye ne-tungsten carbide burr yokusika nokugaya ezinye izinto.

Kusukela kulesi sihloko, singakwazi ukukhiqizwa kwe-tungsten carbide powder, okuwumkhiqizo wemikhiqizo eminingi ye-tungsten carbide nama-tungsten alloys. Ngakho-ke ukugcina i-tungsten carbide powder ngokufanelekile kubalulekile ukuqinisekisa ukuthi imikhiqizo ye-tungsten carbide ingakwazi ukugcina ukusebenza kwayo.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
