Qhathanisa nensimbi ejwayelekile,insimbi ekhethekileInamandla aphezulu kanye nobunzima, izakhiwo ezibonakalayo, izakhiwo zamakhemikhali, ukwenziwa kwe-biocomp, ukusebenza kwenqubo. Kephainsimbi ekhethekileinezici ezithile ezihlukile zensimbi ejwayelekile. Ngensimbi ejwayelekile abantu abaningi baqonda ngokwengeziwe, kepha ngezimpawu zeinsimbi ekhethekile, abantu abaningi bathi badideke kakhudlwana. Ngakho-ke, lesi sihloko esilandelayo sigxile kwizici zeama-special nsimbi.
Izici zensimbi ekhethekile:
Qhathanisa nensimbi ejwayelekile,insimbi ekhethekileInezici zobumsulwa obuphezulu, ukufana okuphezulu, isakhiwo se-Ultra-sihle nokunemba okuphezulu:
(1)Ubumsulwa obukhulu.Okuqukethwe yigesi kanye nokufakwa (kufaka phakathi ukufakwa kwensimbi ngephuzu eliphansi lokuncibilika) ngensimbi kungancishiswa. Lapho ubumsulwa bensimbi bukhuphuka bube ngomkhawulo othile, hhayi kuphela izakhiwo zangempela zensimbi ezingathuthukiswa kakhulu, kepha futhi nezindawo ezintsha zensimbi zinganikezwa. Isibonelo, okuqukethwe kwe-oxygen entanjeni kwensimbi kuncishiswa kusuka ku-30 ​​× 10-6 kuye ku-5 × 10-6, futhi impilo evuthayo inyuswa izikhathi ezingama-30. Ama-auntenituc auntenituc steanless steanless anivikelekile ekucindezelekeni kokugqwala lapho okuqukethwe kwe-phosphorus kuncishiswa ku-3 × 10-6. Ekupheleni kwekhulu lama-20, izinga lokuhlanzeka (10) lensimbi elingatholwa ngokukhiqizwa kwabantu abaningi yile: hydrogen ≤1, i-oxygen ≤10, i-pulfur ≤10, i-nitrogen ≤15, phosphorus

(2) ukufana okuphezulu.Ukuhlukaniswa kokwakheka kwensimbi kuholela ekwakhekeni okungalingani nezakhiwo zensimbi, okungenye yezizathu ezibalulekile zokwehluleka kokuqala kwezingxenye zensimbi nobunzima bokusebenzisa ngokuphelele izici ezingaba khona. Ubuchwepheshe bokukhiqiza banamuhla kufanele benze ukufana kwensimbi Finyelela: Ukuguquguquka kwe-Harture ye-Harderable yemoto ye-Hartiable ye-± 3HRC; Okuqukethwe yikhabhoni, i-nickel, molybdenum ≤ ± 0.01%, kanye ne-manganese kanye chromium ≤ ± 0.02% alawulwa ngokunembile. Usayizi wokusanhlamvu wensimbi ngemuva kokuqala ukujulaka kuyinto eyindilinga futhi usayizi 000 000 0.2 μm. Izakhiwo zemishini zensimbi engamelana nezinyembezi ze-lamitated
(3) Isakhiwo se-Ultra-Fine.Ukuqiniswa kwe-estra-Fine-Fine-FiceSture kuwukuphela kwendlela yokuqinisa ongakhulisa amandla wensimbi ngaphandle kokuncipha noma ukukhulisa kancane ubunzima. Isibonelo, lapho usayizi wokusanhlamvu wamandla aphezulu wensimbi afc77 acwengekile kusuka ku-60μM kuya ku-2.3 μm, i-Fracture Gutiveness Kic inyuka kusuka ku-100 kuye ku-220MPA · · am. Ukushisa okufudumele kwe-Embrittlement lokushisa kwepuleti lensimbi eboshwe nge-nuclear reactoror transsure Pressure Vessel ngu-150 ~ 250 ℃ ngenkathi insimbi ethosiwe enhle ingu-50 ~ 70 ℃. Lapho usayizi we-carbide ongenayo insimbi ulungile ku-≤0.5μm, impilo ethwala izothuthukiswa kakhulu.
(4) Ukunemba okuphezulu. Ama-special nsimbikufanele ibe nekhwalithi enhle ebusweni nokubekezelelana okuncane. Ukunemba kwe-Hot Roll Rolled Rood kufinyelela ku-
