Ungaqinisekisa Kanjani Usayizi Womkhiqizo we-Tungsten Carbide

I-Tungsten carbide iyithuluzi lesibili elinzima kakhulu emhlabeni, ngemuva kwedayimane. I-Tungsten carbide idume ngezakhiwo zayo ezinhle, njengokuqina okuphezulu, ukumelana nokugqokwa, ukumelana nomthelela, nokuqina, ngakho-ke zinhle ukwenziwa zibe yimikhiqizo ehlukene ye-tungsten carbide.

Njengoba sonke sazi, lapho senza umkhiqizo we-tungsten carbide, sihlala sisebenzisa i-powder metallurgy, ehlanganisa ukuhlanganisa nokufaka i-sintering. Futhi njengoba sike sakhuluma ngaphambili, imikhiqizo ye-tungsten carbide izoncipha ngemuva kokucwiliswa. Lokhu kungenxa yokuthi ukugeleza kwepulasitiki kuyanda ngesikhathi sokushisa. Lesi simo sivamile, kodwa-ke, singaletha izinkinga ekukhiqizeni imikhiqizo ye-tungsten carbide. Lokho kusho ukuthi uma sidinga umkhiqizo we-tungsten carbide onobude obungu-16mm, asikwazi ukwenza isikhunta esinobude obungu-16mm futhi siyihlanganise kulowo sayizi ngoba izoba yincane ngemva kokusinsa. Ngakho-ke siqinisekisa kanjani ubukhulu bemikhiqizo ye-tungsten carbide?

Into ebaluleke kakhulu yi-coefficient yokunciphisa.

I-constriction coefficient ingelinye lamanani abonakalayo ajwayelekile kubunjiniyela. Ezinye izinto zivame ukubangela ukuncipha kwevolumu ngenxa yezinguquko zazo, ukushintsha kwezinga lokushisa kwangaphandle, izinguquko zesakhiwo, nokushintsha kwezigaba. I-constriction coefficient ibhekisela esilinganisweni sesilinganiso sokuminyanisa nenani le-constriction factor.

Izinto eziningi zizothinta i-coefficient yokufingqa. Ikhwalithi ye-tungsten carbide powder exutshwe ne-cobalt powder kanye nenqubo yokuhlanganisa izoba nomthelela ku-coefficient yokunciphisa. I-constriction coefficient ingaphinde ithintwe ezinye izidingo zemikhiqizo, njengokwakheka kwempushana exutshwe, ukuminyana kwempushana, uhlobo nenani le-ejenti yokwakha, kanye nokuma nosayizi bemikhiqizo ye-tungsten carbide.

Lapho sikhiqiza imikhiqizo ye-tungsten carbide, sizokwenza isikhunta esihlukile sokuhlanganisa i-tungsten carbide powder. Kubonakala sengathi lapho sihlanganisa imikhiqizo ye-tungsten carbide ngobukhulu obufanayo, singasebenzisa isikhunta esifanayo. Kodwa eqinisweni, asikwazi. Uma sikhiqiza imikhiqizo ye-tungsten carbide ngosayizi ofanayo kodwa amabanga ahlukene, akufanele sisebenzise isikhunta esifanayo ngoba imikhiqizo ye-tungsten carbide emabangeni ahlukene izohluka ngobuningi, okuzothinta i-coefficient ye-constriction. Isibonelo, i-coefficient yokuminyanisa yebanga elivame kakhulu i-YG8 iphakathi kuka-1.17 no-1.26.

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