Cabanga ungumnikazi wendandatho engasoze yaklwebheka futhi ezohlala yinhle njengosuku osanda kuyithenga ngalo.
I-tungsten ehlanzekile iyinsimbi yensimbi ehlala isikhathi eside kakhulu eyakha ingxenyana encane yoqweqwe lomhlaba (cishe 1/20 ounce ngethoni ngalinye ledwala). I-Tungsten ayenzeki njengensimbi emsulwa emvelweni. Ihlala ihlanganiswe njengenhlanganisela nezinye izinto. Ukumelana okuphakeme nokunemba kukwenza kube ukukhetha okufanele ubucwebe. Insimbi ihlanganiswe ne-nickel binder ephakeme ukukhiqiza ucezu lobucwebe obunzima, obuqinile nolunwaya.
I-Platinum, i-palladium noma izindandatho zegolide zinekhono lokuklwebha, ukufenda nokugoba kalula. Izindandatho ze-Tungsten azigobi futhi zizohlala zibukeka zizinhle njengosuku owaluthenga ngalo okokuqala. I-Tungsten iyinsimbi enzima futhi eqinile. Ungayizwa ikhwalithi esindayo esisindayo ku-tungsten. Uma uhlanganisa isisindo esiqinile nopholishi waphakade we-tungsten ndawonye eringini elilodwa, ukhiqiza uphawu oluphelele lothando lwakho nokuzibophezela.
Amaqiniso Nge-Tungsten:
Uphawu Lwamakhemikhali: W
Inombolo ye-athomu: 74
Indawo yokuqhafaza: 10,220 degrees Fahrenheit (5,660 degrees Celsius)
Ubuningi: ama-ounces angu-11.1 nge-intshi ngayinye eyi-cubic (19.25 g / cm)
Ama-Isotopu: Ama-Isotopu Emvelo Ayisihlanu (cishe amasotopu wokuzenzela angamashumi amabili nanye)
Igama Umsuka: Igama elithi "tungsten" livela kumagama aseSweden athi tung and sten, okusho ukuthi “itshe elisindayo”
Inqubo Yokukhiqiza:
I-Tungsten powder igcwele emasongweni ensimbi aqinile kusetshenziswa inqubo ebizwa ngokuthi i-sintering. Umshini ucindezela uqinisa impuphu ibe indandatho ingenalutho. Iringi iyashiswa esithandweni somlilo ngo-2 200 degrees Fahrenheit (1,200 degrees Celsius). Amaqembu womshado we-tungsten alungele ukuhlala sintering. Kusetshenziswa inqubo eqondile yokuhlunga. Lokhu kuhilela ukudlulisa amandla kagesi ngqo kwindandatho ngayinye. Njengoba ukunyuka kwamanje, iringi ishisa ifike ku-5,600 degrees Fahrenheit (3,100 degrees Celsius), inciphe ibe yindandatho eqinile njengoba impuphu iqumbana.
Indandatho ibe seyakhiwa bese ipholishwa kusetshenziswa amathuluzi edayimane. Okwezindandatho ezinesiliva, igolide, i-palladium, iplatinamu noma okufakwayo komugqa wegane, amathuluzi edayimane amba isiteshi enkabeni yeringi. Insimbi eyigugu ifakwe ngaphakathi eringini ngaphansi kwengcindezi iphinde ipholishwe.
Izindandatho zeTungsten Vs Tungsten Carbide Rings?
Kunomehluko omkhulu phakathi kwendandatho ye-tungsten nendandatho ye-tungsten carbide. I-Tungsten ngesimo sayo esiluhlaza iyinsimbi empunga ephuka futhi kunzima ukusebenza nayo. Insimbi empunga yakhiwa ngokugaywa ibe yimpuphu nokuyihlanganisa nezakhi zekhabhoni nokunye. Konke lokhu kucindezelwe ndawonye ukwakha i-tungsten carbide. Kuyaqabukela uthola indandatho ye-tungsten emsulwa, kepha ikhona. Amasongo e-Tungsten carbide aqinile futhi ayamelana nokuklwebha kunanoma iyiphi enye indandatho.
Esinye sezici ezinkulu kakhulu zeringi ye-tungsten carbide ukuphikisana kwayo ekuqaleni. Kunezinto ezimbalwa kuphela kule planethi ezingaklwebha iringi ye-tungsten efana nedayimane noma okuthile kobulukhuni obulinganayo.
Indandatho yethu ngayinye yetungsten iza newaranti yokuphila engakaze ibonwe. Uma kungenzeka noma yini yenzeke eringini lakho, mane usazise futhi sizoyinakekela.
Ingabe amasongo akho e-tungsten aqukethe i-cobalt?
Lutho neze! Kunamasongo amaningi e-tungsten carbide emakethe aqukethe i-cobalt. Asinayo i-cobalt emasongweni ethu. ICobalt ingxubevange eshibhile abanye abathengisi abaningi abayisebenzisayo ukukhiqiza amasongo e-tungsten. I-cobalt engaphakathi kwezindandatho zayo ithinta uketshezi lwemvelo lomzimba futhi izokona, iphendule indandatho yakho ibe mpunga obuthuntu bese ishiya ibala elinsundu noma eliluhlaza emunweni wakho. Ungakugwema lokhu ngokuthenga eyodwa izindandatho zethu ze-tungsten carbide ezingenayo i-cobalt.
