Ukwenzaintambo ye-tungsten kuyinqubo eyinkimbinkimbi, enzima.Inqubo kumele ilawulwe ngokuqinile ukuze kuqinisekiswe i-chemistry efanele kanye nezakhiwo ezifanele zomzimba zocingo oluphelile.Ukusika amakhona kusenesikhathi ngenqubo yokunciphisa amanani entengo kungaholela ekusebenzeni kabi komkhiqizo oqediwe.Ungaqiniseka ukuthi izintambo ezivela ku-'Forgedmoly' zenziwe ngokuqhubekayo zafika ezingeni eliphezulu kakhulu futhi zizosebenza kahle ngokuqhubekayo.

Ukucwenga i-tungsten ensimbi angeke kwenziwe ngokuncibilikiswa kwendabuko kusukela ngaleso sikhathii-tungsteninephuzu lokuncibilika eliphakeme kunanoma iyiphi insimbi.I-Tungsten ikhishwa ku-ore ngochungechunge lokusabela kwamakhemikhali.Inqubo ngqo iyahlukahluka ngomkhiqizi kanye nokwakheka kwe-ore, kodwa insimbi iyachotshozwa bese yosiwe futhi/noma ithunyelwe ngokuhlukahluka kwamakhemikhali, imvula, nokuwashwa ukuze kutholwe i-ammonium paratungstate (APT).I-APT ingathengiswa ngokwezentengiselwano noma iqhubeke icutshungulwe ibe yi-tungsten oxide.I-tungsten oxideingagazingwa emkhathini we-hydrogen ukuze idale impushana ye-tungsten emsulwa ngamanzi njengomkhiqizo ovelayo.I-Tungsten powder iyindawo yokuqala yemikhiqizo yokugaya i-tungsten, kuhlanganise nocingo.

Manje njengoba sinempushana ye-tungsten ehlanzekile,silwenza kanjani ucingo?

1. Ukucindezela
I-Tungsten powderiyahlungwa futhi ixutshwe.Isibopho singengezwa.Inani elinqunyiwe liyakalwa bese lilayishwa esikhunjeni sensimbi esilayishwa emshinini wokunyathelisa.Impushana ihlanganiswe ibe yibha ehlangene, kodwa entekenteke.Isikhunta siyahlukaniswa futhi ibha iyasuswa.Isithombe lapha.

2. Ukwethula
Ibha entekenteke ifakwa esikebheni sensimbi esiphikisayo futhi ilayishwe esithandweni esinomoya we-hydrogen.Izinga lokushisa eliphezulu liqala ukuhlanganisa izinto ndawonye.I-Material cishe i-60% - 70% yokuminyana okugcwele, nokukhula okuncane noma akukho okusanhlamvu.

3. I-Sintering Egcwele
Ibha ilayishwa ebhodleleni elikhethekile lokwelapha elipholile ngamanzi.Ugesi uzodluliswa kubha.Ukushisa okukhiqizwa yilokhu kwamanje kuzobangela ibha ukuthi iminyene ibe ngu-85% kuya ku-95% wokuminyana okugcwele futhi inciphe ngo-15% noma ngaphezulu.Ukwengeza, amakristalu e-tungsten aqala ukwakheka ngaphakathi kwebha.

4. Ukushwibeka
Ibha ye-tungsten isiqinile manje, kodwa ibhibhana kakhulu ezingeni lokushisa legumbi.Ingenziwa ithambile ngokukhuphula izinga lokushisa layo libe phakathi kuka-1200°C kuya ku-1500°C.Kuleli zinga lokushisa, ibha ingadluliswa nge-swager.I-swager iyisisetshenziswa esinciphisa ububanzi benduku ngokuyidlulisa ku-dayisi eklanyelwe ukubethela induku cishe ngemivimbo engu-10,000 ngomzuzu.Ngokuvamile i-swager izonciphisa ububanzi cishe ngo-12% ngokudlula ngakunye.Ukuguquguquka kwelula amakristalu, kwakha isakhiwo esine-fibrous.Nakuba lokhu kuyinto efiselekayo kumkhiqizo oqediwe we-ductility namandla, ngalesi sikhathi induku kufanele ikhululwe ukucindezeleka ngokushisa kabusha.Ukushwibeka kuyaqhubeka kuze kube yilapho induku iphakathi kwamayintshi angu-.25 no-.10.

5. Umdwebo
Izintambo ezigoqiwe ezingaba amayintshi angu-.10 manje zingadonswa nge-dies ukuze kwehliswe ububanzi.Ucingo luyagcotshwa futhi ludonswe nge-dies of tungsten carbide noma idayimane.Ukuncishiswa okuqondile kobubanzi kuncike kumakhemikhali aqondile kanye nokusetshenziswa kokugcina kocingo.Njengoba ucingo ludonswa, imicu iyaphinda ibe yinde futhi amandla aqine ayakhula.Ezigabeni ezithile, kungase kudingeke ukuba unqamule ucingo ukuze uvumele ukucutshungulwa okwengeziwe.Intambo ingadwetshwa kahle njengamasentimitha angu-.0005 ububanzi.

Lokhu ukwenza lula kwenqubo eyinkimbinkimbi, elawulwa ngokuqinile.Uma udinga ulwazi oluningiliziwe noma unemibuzo sicela usithinte.
