Uma uzwa 'izinkonzo zokuphonsa i-wax ezilahlekile,' izingqondo eziningi zigxumela kubucwebe obuyinkimbinkimbi noma izingcezu zobuciko. Leso isithombe esivamile, kodwa emkhakheni wezimboni, isilo esihluke ngokuphelele. Kuncane mayelana ne-filigree ethambile futhi okuningi mayelana nokukhiqiza ubuqotho obuphezulu, izingxenye eziyinkimbinkimbi ngokuvamile ezingenziwa nganoma iyiphi enye indlela. Ubuchwepheshe bangempela abukho nje ekuncibilikeni kwensimbi; kusekulawuleni lonke iketango—kusuka ekuzinzeni kohlangothi lwephethini ye-wax ukuya ekungeneni kwegobolondo kanye nokwelashwa kokushisa kokugcina. Amaklayenti amaningi afika ecabanga ukuthi kuyindlela elula yokufaka imishini, kodwa ukubekezelela ukunqwabelana kusuka ku-wax kuya ensimbi kuyi-saga ngokwayo.
Umnyombo Wenqubo: Konke Kusemininingwaneni
Ake sikhulume ngengcina. Akuwona wonke ama-wax omjovo adalwe alingana. Ukuze uthole i-turbine blade, udinga inhlanganisela ecishe ibe nguziro ukushwabana kanye nokuqina okuphezulu ukuze ubambe lawo maphrofayili e-airfoil. Ngomzimba we-valve ojwayelekile, i-wax evamile, eyongayo isebenza. Inketho lapha isho yonke into ezansi nomfula. Ngibone amaphrojekthi aya eceleni ngoba i-wax ikhethwe ngezindleko, okuholela ekuqhekekeni kwegobolondo ngesikhathi se-dewax noma ukuqedwa kwensimbi okungamukeleki. Kuyisinqumo esiyisisekelo abaningi abangasinaki.
Isigaba sokwakha amagobolondo yilapho ubuciko buhlangana nesayensi. Akukhona nje ukucwilisa kanye ne-stuccoing. I-slurry viscosity, umswakama wendawo yokomisa kanye nezinga lokushisa, usayizi wezinhlamvu ze-stucco nokusabalalisa - ungqimba ngalunye luwushintsho olulawulwayo. Igobolondo elincanyana kakhulu lingase liphuke ngesikhathi lithela; bukhulu kakhulu, futhi kungavimbela ukuphuma kwegesi, kubangele i-porosity. Sake saba neqeqebana le-pump impeller lapho abalandeli bokomisa bezingalinganiswe kahle, kwakha i-gradient yomswakama. Umphumela? Amagobolondo abebukeka elungile kodwa abe namandla angaguquki, okuholela ku-30%. Ukulungiswa bekuyinto evamile kodwa kubucayi: ukulungisa kabusha izilawuli zemvelo nokusebenzisa ukuhlola okuvamile.
Bese kufika ukutubeka nokuthela. Yilapho 'i-wax elahlekile' yenzeka khona ngempela. Umjikelezo wesithando somlilo kufanele uqede ngokuphelele i-wax ngaphandle kokuqhekeka igobolondo le-ceramic. Ukushesha kakhulu, nokushaqeka okushisayo kwenza umonakalo. Ukuthela ngokwako, ikakhulukazi ama-alloys afana ne-nickel-based noma i-cobalt-based superalloys, umdanso onembile wezinga lokushisa nesivinini. Awugcini nje ngokugcwalisa isikhunta; ulawula ukuqiniswa ukuze unciphise ukuhlukaniswa nokuklebhuka okushisayo.
Izinto Ezibalulekile: Akuyona Nje Insimbi
Lokhu kuyiphuzu elikhulu lokuhlukanisa. Isitolo esithi siphatha insimbi engagqwali singase sisebenze kahle ku-304 noma 316. Kodwa uma ungena endaweni yezinsimbi ezingenasici eziyi-duplex, noma amamaki aqinisa imvula njengo-17-4PH, yonke inqubo idinga ukulungiswa. Idizayini yesistimu yokungena, izinga lokushisa lokuthulula, ukwelashwa kokushisa kwangemuva kokusakazwa—konke kuqondene ngqo nensimbi yengxubevange.
