Emikhakheni yokukhiqiza ephezulu kanye nobunjiniyela bokunemba, impilo yesevisi yezingxenye zemishini ihlobene ngqo nokuzinza kokukhiqiza kanye nezindleko zokusebenza. Izingxenye ze-granite ze-ZHHIMG, ezinobukhulu obuphezulu kakhulu obungu-3.1g/cm³ kanye ne-modulus enwebekayo evelele engu-50GPa, zidlule emikhawulweni yezinto zendabuko, zafinyelela impilo yesevisi engaphezu kweminyaka engama-30 futhi zaba "isilinganiso sokuphila isikhathi eside" ekusetshenzisweni kwezimboni. Izimiso zesayensi yezinto ezibonakalayo ngemuva kwayo zembula ukuxhumana okujulile phakathi kokusebenza nokuqina.
1. 3.1g/cm³ ukuminyana: Isakhiwo esiqinile sakha isisekelo esiqinile
Ubuningi obukhulu bezingxenye ze-granite ze-ZHHIMG buvela ekwakhekeni kwazo okuyingqayizivele kwamaminerali kanye nenqubo yokwakheka kwe-geological. I-granite yakhiwe kakhulu ngamakristalu amaminerali njenge-quartz, i-feldspar kanye ne-mica ahlanganiswe eduze. Ngaphansi kwendawo ye-geological yokushisa okuphezulu kanye nokucindezela okuphezulu, lawa maminerali aqine futhi aqine amakhulu ezigidi zeminyaka, akha isakhiwo esiminyene esicishe singabi nama-pore (ama-porosity < 0.1%). Lokhu kuqina kunikeza izingxenye izinzuzo ezintathu eziyinhloko:
Ukumelana nokuguguleka okuvelele: Ubuningi obukhulu busho ukuthi ama-athomu angaphezulu kwezinto ahlelwe eduze, okwenza kube lula ukuguga nokuklwebheka ngesikhathi sokungqubuzana isikhathi eside noma ukuthintana ngomshini. Isibonelo, ekusetshenzisweni kwezinsimbi zokuqondisa amathuluzi omshini onembile, izingxenye zegranite ze-ZHHIMG zingamelana nokunyakaza okuphindaphindayo okungaphezu kwesigidi, ngokulahlekelwa kokunemba kobuso okungaphansi kuka-0.01μm, okudlula kakhulu lokho kwezinto zendabuko ezifana nensimbi ephonswe.
Ukumelana nokugqwala okuthuthukisiwe: Isakhiwo esiminyene sihlukanisa ngempumelelo ukuhlasela kwezinto zamakhemikhali zangaphandle. Kungakhathaliseki ukuthi yi-reagents ye-asidi ne-alkali, amabala kawoyela wezimboni noma umoya omanzi, ukuqina kwamakhemikhali kwezingxenye ze-granite ze-ZHHIMG akuthinteki. Ububanzi bayo bokubekezelela i-pH bungu-1-14, futhi ingasetshenziswa isikhathi eside ezindaweni ezimbi kakhulu ngaphandle kokugqwala.
Ukuqina kobukhulu obuthuthukisiwe: Izinto eziqinile kakhulu zinokuqhutshwa kokushisa okuphansi, okwenza kube nzima ukuthi ukushisa kusabalale ngokushesha ngaphakathi kwengxenye, ngaleyo ndlela kunciphisa ukugcwala kokucindezeleka kokushisa okubangelwa izinguquko zokushisa. Kuhlanganiswe ne-coefficient yayo yokwanda kokushisa ephansi njenge-(4-8) ×10⁻⁶/℃, izinguquko zobukhulu bezingxenye ze-granite ze-ZHHIMG zihlala zilawulwa ezingeni le-micrometer ngaphakathi kobubanzi bokushisa obuqala ku--40 ℃ kuya ku-120℃, okuqinisekisa ukunemba kokusetshenziswa kwesikhathi eside.
Ii. I-50GPa Elastic Modulus: Isimangaliso Semishini Sokuhlanganisa Ukuqina Nokuguquguquka
I-modulus elastic ibonisa ikhono lento yokumelana nokuguquguquka kwe-elastic. I-modulus elastic engu-50GPa yezingxenye ze-granite ze-ZHHIMG izenza zikwazi ukukhombisa isici "sokuhlanganisa ukuqina nokuguquguquka" lapho zithwalwa imithwalo:
Ukuqina okuphezulu kokumelana nokuguquguquka: Lapho ubhekene nokucindezela okunzima kwesikhathi eside noma ukudlidliza okuphezulu okuvela emishinini esindayo, i-modulus ye-elastic ye-50GPa iqinisekisa ukuthi ingxenye idlula kuphela ekuguqukeni okuncane kakhulu kwe-elastic. Isibonelo, ekusetshenzisweni kwamapulatifomu okuhlola ama-blade enjini ye-aero, izingxenye ze-granite ze-ZHHIMG zingasekela imishini yokuhlola enesisindo esingaphezu kwamathani ama-2, futhi ukushintshashintsha kwe-flatness kulawulwa ngaphakathi kwe-±0.1μm/m, okuqinisekisa ukunemba kokulinganisa amashumi eminyaka.
Ukucindezeleka kokuvimba ukuze kuvinjelwe ukuphuka: I-modulus enwebekayo ephezulu akusho ukuthi into iyaphuka noma iqinile. Isakhiwo sekristalu yamaminerali ngaphakathi kwe-granite siyinika amandla ahlukile okusabalala kokucindezeleka. Uma ingaphansi kwemithwalo yokushaywa, izingxenye zingavimba amandla ngokusebenzisa ukuhamba okuncane phakathi kwamakristalu amancane, zigweme ukusabalala kwemifantu okubangelwa ukugcwala kokucindezeleka. Ukulinganisa kwangempela kwenkampani ethile yokukhiqiza i-semiconductor kukhombisa ukuthi ipulatifomu yokuthwala i-granite ye-ZHHIMG ayizange ilimale ngenxa yokushaywa yimishini okungamashumi ezinkulungwane.
Iii. Amasu Okucubungula Esayensi: Khulula Amandla Aphezulu Ezinto Ezisetshenziswayo
Ngaphezu kwezinzuzo ezingokwemvelo zale nto, ubuchwepheshe bokucubungula obunembile kakhulu be-ZHHIMG buveza amandla okusebenza kwe-granite. Ngokusebenzisa amasu anjengokupholisha kwe-magnetorheological kanye nokugaya imisebe ye-ion, ubulukhuni bomphezulu wezingxenye bungancishiswa bube yi-Ra≤0.02μm, futhi ubuthabala bungafinyelela ku-±0.1μm/m. Lokhu kucubungula okunembile kakhulu akugcini nje ngokunciphisa amaphutha omphezulu kodwa futhi kugwema ukuncishiswa kokuphila okubangelwa yimifantu emincane, okuvumela ukusebenza kwento ukuthi kusebenze ngokuzinzile isikhathi eside.
Kusukela esisekelweni sobuningi obungu-3.1g/cm³ kuya ekusekelweni kwe-modulus kwe-50GPa, izingxenye ze-granite ze-ZHHIMG zithatha isayensi yezinto ezibonakalayo njengengqikithi futhi zihlanganisa ngokujulile izakhiwo zemvelo nobuchwepheshe obusezingeni eliphezulu. Njengoba isikhathi senkonzo singaphezu kweminyaka engama-30, akugcini nje ngokunciphisa kakhulu izindleko zokushintsha imishini yamabhizinisi, kodwa futhi kukhuthaza ukuthuthuka kokukhiqiza ngokunemba ukuze kusebenze isikhathi eside kanye nokuthembeka okuphezulu, kube yisibonelo "sokutshalwa kwezimali kanye kanye, izinzuzo zokuphila konke" emkhakheni wezimboni.
