99.95% amabhawodi wokuxhuma isikulufa se-tungsten ahlanzekile.
Ukukhiqizwa kwe-tungsten ehlanzekile (isb. 99.95%) amantongomane, amawasha, izikulufu namabhawodi kuvame ukubandakanya izinqubo eziyinkimbinkimbi eziklanyelwe ukuqinisekisa ukuthi umkhiqizo osuphelile unezakhiwo ezidingekayo zomzimba namakhemikhali, ikakhulukazi ezisetshenziswa ezinamazinga okushisa aphezulu, ukucindezela okukhulu noma lapho ukugqwala okukhulu. ukumelana kuyadingeka.Okulandelayo ukubuka kabanzi kwale nqubo yokukhiqiza:
Ukukhiqizwa Kwe-Tungsten Powder: Okokuqala, ukuhlanzeka okuphezulu kwe-tungsten powder kulungiswa ngamakhemikhali noma izindlela zomzimba.Lokhu kungase kuhlanganise ukuncishiswa kwe-tungstic acid noma i-tungsten oxide ukuze kukhiqizwe impushana ye-tungsten.
Ukuxuba: Impushana ye-Tungsten ixutshwa nezinto ezingaba ingxubevange kanye/noma izibophezelo ukuze kuthuthukiswe ukucutshungulwa kwayo noma izakhiwo zokugcina.
I-Pelletizing: Ingxube ingase ifakwe i-pelletized ngezinyathelo ezilandelayo zokucindezela.
I-Cold Isostatic Pressing (CIP) noma I-Hot Isostatic Pressing (HIP): Izimpushana ezixubile zicindezelwa ngaphansi kwengcindezi ephezulu ukuze kube nesimo esinqunyiwe.Lesi sinyathelo ngokuvamile senziwa ekamelweni lokushisa (ukucindezela okubandayo), kodwa futhi kungenziwa ngaphansi kwezimo ezishisayo (ukucindezela okushisayo) ukuthuthukisa ukuminyana kanye nezakhiwo zemishini.
I-Sintering: Ingxenye ecindezelwe ifakwa emazingeni okushisa aphezulu ukuze kuncishiswe i-porosity futhi kwandiswe amandla kanye nokuminyana.I-Tungsten ifakwe emanzini emazingeni okushisa aphezulu kakhulu, ngokuvamile angaphezu kuka-1500 ° C.Kwezinye izimo, i-vacuum noma i-protective atmosphere sintering ingase isetshenziselwe ukuvimbela ukwethulwa kokungcola.
Umshini: Ingxenye ye-sintered yenziwa ngomshini njengoba kudingeka ukuze kuzuzwe usayizi wokugcina kanye nokuma.Ukuqina okuphezulu kwe-tungsten kudinga umshini ngamathuluzi we-carbide noma wedayimane.
Ukulungiselela Ubuso: Lokhu kungase kuhlanganise ukupholisha, ukuhlanza noma ukuhlanganisa ukuze kuthuthukiswe ukumelana nokugqwala, ukunciphisa i-coefficient of friction noma ukuthuthukisa ukubukeka.
Ukuhlolwa nokuhlolwa: Umkhiqizo wokugcina uzohlolwa ngokulawulwa kwekhwalithi okuqinile, okuhlanganisa nokuhlolwa kokunemba kobukhulu, ukuminyana, ubulukhuni namandla ukuze kuqinisekiswe ukuthi uhlangabezana nezimfuneko zohlelo oluthile.
Ngenxa yezakhiwo ezikhethekile ze-tungsten, yonke inqubo yokukhiqiza idinga ukulawula okunembile, okuhlanganisa ukuphathwa okuqinile kwezinga lokushisa, ingcindezi kanye nomkhathi.Ngaphezu kwalokho, inqubo yokwenza imishini kanye ne-sintering yemikhiqizo ye-tungsten nayo idinga kakhulu imishini, idinga izinto zokwakha kanye nezingxenye ezimelana namazinga okushisa aphezulu kanye nokugqwala.
Amantongomane ahlanzekile e-tungsten, amawasha, izikulufu namabhawodi adume kakhulu ezimeni ezahlukahlukene zohlelo ezidinga ukusebenza ngokwedlulele ngenxa yezakhiwo zazo eziyingqayizivele zomzimba namakhemikhali.Ngezansi ezinye zezicelo ezijwayelekile zalezi zingxenye ze-tungsten:
I-Aerospace
Emkhathini, izingxenye ze-tungsten zisetshenziswa ezindaweni lapho zingaphansi kwamazinga okushisa aphakeme kakhulu nezingcindezi, njengakumamotho amarokhethi nezinye izingxenye ezibalulekile zemikhumbi-mkhathi.Iphuzu eliphakeme lokuncibilika le-tungsten liqinisekisa ukuthi lezi zingxenye zigcina ubuqotho bazo besakhiwo nokusebenza emazingeni okushisa aphezulu.
Ama-reactors enuzi
Ekusetshenzisweni kobuchwepheshe benuzi, ukuminyana okuphezulu kwe-tungsten kuyenza ibe into efanelekile yokuvikela imisebe.Amantongomane namabhawodi e-Tungsten asetshenziselwa ukuvikela nokuxhuma izingxenye zesakhiwo kuma-reactors enuzi, okunikeza isiqinisekiso esithembekile sokuphepha emisebeni.
Izithando Zokushisa Eziphakeme
Izingxenye ze-Tungsten nazo zisetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezithandweni zokushisa eziphezulu, ikakhulukazi lapho amazinga okushisa aphakeme kakhulu adingeka ekusetshenzisweni kwezinto ezibonakalayo noma ukusabela kwamakhemikhali.Iphuzu eliphezulu lokuncibilika namandla e-tungsten kubaluleke kakhulu ngaphansi kwalezi zimo.
Imishini yezokwelapha
Embonini yezokwelapha, ikakhulukazi ekwelapheni ngemisebe kanye nemishini yokuxilonga, izingxenye ze-tungsten zisetshenziswa kabanzi ngenxa yamakhono azo amahle kakhulu okuvikela imisebe.Amantongomane nama-bolts e-Tungsten aqinisekisa ukuzinza kwesakhiwo semishini ngenkathi evikela opharetha neziguli emisebeni engadingeki.
Ukuhlolwa kwesayensi
Izingxenye ze-Tungsten zivame ukusetshenziswa kumishini yokuhlola enengcindezi ephezulu kanye namazinga okushisa aphezulu emkhakheni wocwaningo lwesayensi, ikakhulukazi ocwaningweni lwesayensi yefiziksi nezinto zokwakha.Ukumelana kwabo namazinga okushisa aphezulu namandla aphezulu kubalulekile empumelelweni yocwaningo.
Izicelo zikagesi nezikagesi
Ukusebenza kahle kukagesi kwe-Tungsten nokumelana nokugqwala kuyenza ibe into ekhethwayo kwezinye izinhlelo zokusebenza zikagesi nezikagesi, isb kuzixhumi zemishini kagesi enamandla amakhulu.
Imboni yokunemba
Kuzinhlelo zokusebenza zezimboni ezinembayo ezidinga ukunemba nokuqina okwedlulele, njengemishini nezinsimbi ezinemba kakhulu, izingxenye ze-tungsten zisetshenziswa kabanzi ukuze zizinze futhi zimelane nokugqokwa kwazo.
Lezi zinhlelo zokusebenza zisebenzisa iphoyinti elincibilikayo le-tungsten eliyingqayizivele, ukuminyana okuphezulu, amandla aphezulu, nezinye izakhiwo ezibonakalayo namakhemikhali, okubonisa indima ebalulekile yezinto ze-tungsten kubuchwepheshe besimanje nezimboni.
