Lapho onjiniyela becacisa imithombo ye-cobalt-60 ye-radiography yezimboni, inzalo, noma imishini yokwelapha umdlavuza, abadingi nje ama-radioisotopes—badinga i-Co-60 elandelekayo, eqinisekisiwe, futhi eqinile ngokomzimba. imithombo. Lowo mehluko ubalulekile. I-"Co 6 factory" ayiyena umhlinzeki ojwayelekile wensimbi eluhlaza ye-cobalt. Ingumkhiqizi onembayo okwazi ukwenza amaphilisi omthombo avaliwe—ngokuvamile avela ku-AMS 5387 cobalt alloy noma ama-superalloy e-T800-grade—amelana nokuhamba ngamabhayisikili ashisayo, ukulimala kwemisebe ye-gamma, kanye nokushaqeka komshini phakathi namashumi eminyaka esevisi. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenzisa indawo eyodwa enjalo e-Qingdao: ethobela i-ISO, ihlanganiswe ngokuqondile, futhi yakhiwe eduze nokulawulwa kwensimbi—hhayi nje ukwenza imishini.
Kungani i-"Co 6 factory" isho okungaphezu kokulingisa noma ukucwenga
Abathengisi abaningi bazibiza ngokuthi “abahlinzeki be-Co 6” ngemva kokuthola ama-pellets e-cobalt kubakhiqizi be-isotope benkampani yangaphandle futhi bawahlanganise ezindlini eziyisisekelo. Leyo ndlela yehluleka ngaphansi kwezimo zomhlaba wangempela. Sibonile amaklayenti ethola imithombo enemifantu emincane odongeni lwe-capsule ngemva kwezinyanga eziyi-18 kuphela zokusetshenziswa ezinhlelweni zokukhipha igazi ezinezinga eliphezulu. Imbangela? Isakhiwo sokusanhlamvu esingaguquki ku-alloy eyisisekelo, ukulawulwa okungekuhle kokwelashwa kokushisa, nokuzinza okunganele kwe-dimensional ngesikhathi sokutywinwa kokushisela. E-QINGDAO QIANGSENYUAN, “imboni ye-Co 6” ibonisa ubunikazi obusuka ekupheleni: ukuthengwa kwempahla eluhlaza okuqinisekisiwe (okuhlanganisa namabhilidi e-AMS 5387 anemibiko yokuhlola egcwele yokugaya), ukutshala imali kwamajiyometri angokwezifiso, ukucutshungulwa kwe-CNC kuya ku-±0.01 mm ukubekezelelana ezindaweni ezibalulekile zokuvala uphawu, kanye nokuhlolwa kwe-helium 97 kwemoto ngayinye ye-ISO 8 egcwele. ukulandeleka—kusuka kunombolo yokuncibilika kuye ekupheleni kokugcina—futhi yonke imithombo ithola ukuqinisekiswa okusebenzayo ngaphansi kokucindezela kokusebenza okulingiswayo nezinga lokushisa.
Amandla amane angaxoxiswana ayikho ifekthri ye-Co 6 engakwazi ukweqa
Imboni yeqiniso ye-Co 6 kufanele ilethe amakhono amane ancike kwelinye—hhayi amathathu, hhayi amahlanu. Ukweqa noma yikuphi ukwethula ingcuphe yokwehluleka kwenkambu:
- Ukuvumelana kwe-Metallurgical kuwo wonke amaqoqo: Imithombo ye-Cobalt-60 ilulaza ngokushesha emingceleni yokusanhlamvu. Siqinisekisa yonke inkatho ye-AMS 5387 sisebenzisa i-optical emission spectroscopy kanye nokuhlaziywa kosayizi wokusanhlamvu kwe-ASTM E112 ngaphambi kokuphonsa. Akukho okuhlukile.
- Ubuqotho be-Dimensional ngaphansi kokuvuvukala kwe-irradiation: Ukuchayeka kwe-Gamma kubangela ukunwetshwa kwe-lattice. Imibhobho yethu esekelwe ku-T800 namapulaki enziwe ngomshini anemikhonto yokudambisa ingcindezi ngamabomu—aqinisekiswa ngokulingisa izinto ezinomkhawulo—bese eguga ku-450°C amahora angu-72 okulethwa ngaphambili ukuze kuzinziswe i-microstructure.
- Ukubekwa uphawu kwe-Hermetic kuqinisekiswe ngaphezu kokuhlolwa okubonakalayo: Ukuhlolwa kwe-weld ebonakalayo kugeja i-porosity engaphansi komhlaba. Zonke izindlu zomthombo we-Co-60 zidlula ukuhlolwa kokuvuza kwe-helium mass spectrometry kokuthi ≤1×10⁻⁹ mbar·L/s—iqine izikhathi eziyishumi kunezimfuneko ze-IAEA SSG-47.
- Ukuthobela i-GD&T yokwethenjelwa kwesixhumi esibonakalayo: Ukungahambi kahle ngesikhathi sokufakwa kudala ukucindezeleka okungalingani ku-capsule. Izindlu zethu zamasilinda ephampu ye-piston kanye nemizimba yama-valve ihlanganisa izici ze-datum ezenziwe ngomshini wokusetha okukodwa ezikhungweni ze-CNC ze-5-axis—akukho ukulungisa kwesibili, alikho iphutha lesitaki.
Lokho amakhasimende akubuzayo ngempela—futhi abangavamile ukukusho ngokuphimisela
"Ingabe ungafanisa ubukhulu bomthombo wethu omdala ncamashi?" Yebo-kodwa lowo akuwona umbuzo wangempela. Ukukhathazeka okungashiwongo ukuthi: "Ingabe lo mthombo omusha uzolingana ne-collimator yethu ekhona ngaphandle kokulungisa kabusha yonke indlela yomugqa?" Siyiphendula ngokuskena izingxenye zefa nge-3D metrology ekhanyayo ehlelekile, bese sikhiqiza amamephu wokuchezuka ngokumelene ne-CAD yegama. Uma umphakeli wangaphambili wekhasimende esebenzise ukusakaza kwesihlabathi kupulaki ye-cobalt alloy, sizobonisa izikena ze-CT zehlangothi necele ezifakazela ukuthi inguqulo yethu yokusakazwa kwe-investimenti iqeda ukuncipha kwangaphakathi kokuncipha eduze kwe-gamma-emitting core. Omunye uvame ukubuza: "Ingabe uyakweseka ukugijima kweziqu ze-batch encane?" Impela—sisebenzisa amaqoqo esibonelo ngaphansi kwezilawuli zenqubo efanayo njengokukhiqiza, okufaka izitifiketi zempahla egcwele namalogi okwelapha ukushisa. Azikho izinqamuleli “zokuhlola kuphela”.
Ukubheka phambili: lapho ukukhiqizwa kwe-Co 6 kuphokophele khona
Umngcele olandelayo awuwona umsebenzi ophakeme—uwukuhlanganisa okuhlakaniphile. Ama-ejensi alawulayo manje adinga imibhalo engamawele edijithali yomthombo ngamunye we-Co-60: hhayi nje izinombolo ze-serial namanani omsebenzi, kodwa amapharamitha akha, amalogi omlando oshisayo, kanye nemiphumela yokuhlola engabhubhisi eshumekwe kumalebula abonakalayo anekhodi ye-QR. I-QINGDAO QIANGSENYUAN isebenzisa ama-matric edatha agcizelelwe nge-laser kuzo zonke izindlu ze-T800, ezixhunyaniswe nezingobo zomlando zamafu ezivikelekile ezinezindlela zokuhlola ezithobela i-ISO 13485 kanye ne-FDA 21 CFR Ingxenye 11. Siphinde siqinisekise izinqubo ezixubile—njenge-post-machining ye-electron-beam yesikhathi sokuphila somthombo obalulekile wokuphinda ucindezelwe kabusha komthombo we-electron-beam. Lokhu akukona ukuthuthuka okuqhubekayo. Ichaza kabusha lokho okulethwa yifekthri ye-Co 6: hhayi nje izingxenye, kodwa isiqinisekiso sokusebenza esiqinisekiswayo ukusuka ekuncibilikeni kuye kumishini.
