Kwimimandla yokwenziwa kwemveliso ephezulu kunye nobunjineli obuchanekileyo, ubomi benkonzo yezixhobo bunxulumene ngokuthe ngqo nokuzinza kwemveliso kunye neendleko zokusebenza. Izixhobo zegranite ze-ZHHIMG, ezinobunzima obuphezulu be-3.1g/cm³ kunye ne-modulus ebalaseleyo ye-50GPa, zidlule kwimida yezixhobo zemveli, zifikelela kubomi benkonzo obungaphezulu kweminyaka engama-30 kwaye zaba "yindlela yokulinganisa ubomi obude" kwizicelo zoshishino. Imigaqo yesayensi yezinto ezisetyenzisiweyo emva kwayo ityhila unxibelelwano olunzulu phakathi kokusebenza kunye nokuqina.
1. 3.1g/cm³ uxinano: Isakhiwo esixineneyo sakha isiseko esiqinileyo
Uxinano olukhulu lwezixhobo zegranite ze-ZHHIMG luvela kulwakhiwo lwazo olulodwa lwezimbiwa kunye nenkqubo yokwakheka kwejoloji. Igranite yenziwe kakhulu ziikristale zezimbiwa ezifana ne-quartz, i-feldspar kunye ne-mica ezidityaniswe ngokusondeleyo. Phantsi kwendawo yobushushu obuphezulu kunye noxinzelelo oluphezulu, ezi zimbiwa ziye zaqina zaza zaqina kangangeminyaka engamakhulu ezigidi, zenza isakhiwo esixineneyo esiphantse singabi nazimbobo (i-porosity < 0.1%). Oku kuqina kunika izixhobo iingenelo ezintathu eziphambili:
Ukumelana nokuguguleka okugqwesileyo: Uxinano oluphezulu luthetha ukuba iiathom ezikumphezulu wezinto zilungelelaniswe ngokusondeleyo, nto leyo eyenza ukuba zingagugi kwaye zingakrweleki ngexesha lokungqubana kwexesha elide okanye ukudibana koomatshini. Umzekelo, ekusebenziseni iireyile zesikhokelo somatshini ochanekileyo, izinto zegranite zeZHHIMG zinokumelana neentshukumo ezingaphezulu kwesigidi eziphindaphindayo, kunye nokulahleka kokuchaneka komphezulu okungaphantsi kwe-0.01μm, okungaphezulu kakhulu kwezinto zemveli ezifana nesinyithi esityhidiweyo.
Ukumelana nokugqwala okwandisiweyo: Isakhiwo esixineneyo sikwahlukanisa ngempumelelo ukuhlaselwa kwezinto zangaphandle zeekhemikhali. Nokuba zi-reagents ze-asidi kunye ne-alkali, amabala eoyile yemizi-mveliso okanye umoya ofumileyo, ukuzinza kweekhemikhali zezinto zegranite ze-ZHHIMG akuchaphazeleki. Uluhlu lwayo lokunyamezela i-pH yi-1-14, kwaye ingasetyenziswa ixesha elide kwiindawo ezixineneyo ngaphandle kokugqwala.
Uzinzo oluphuculweyo lobukhulu: Izinto ezinobunzima obuphezulu zine-thermal conductivity ephantsi, nto leyo eyenza kube nzima ukuba ubushushu busasazeke ngokukhawuleza ngaphakathi kwecandelo, ngaloo ndlela kunciphisa uxinzelelo lobushushu olubangelwa kukutshintsha kobushushu. Xa zidityaniswe ne-thermal expansion coefficient yayo ephantsi njenge (4-8) × 10⁻⁶/℃, utshintsho lobukhulu bezinto ze-granite ze-ZHHIMG luhlala lulawulwa kwinqanaba le-micrometer ngaphakathi kobubanzi bobushushu obuphakathi kwe--40 ℃ ukuya kwi-120℃, ukuqinisekisa ukuchaneka kokusetyenziswa kwexesha elide.
Ii. I-50GPa Elastic Modulus: Ummangaliso Womatshini Wokudibanisa Ukuqina Nokuguquguquka
I-elastic modulus ibonisa amandla ezinto zokumelana nokuguquguquka kwe-elastic. I-50GPa elastic modulus yezinto ze-granite ze-ZHHIMG izenza zikwazi ukubonisa uphawu "lokudibanisa ukuqina kunye nokuguquguquka" xa zithwalwa yimithwalo:
Ukuqina okuphezulu ukumelana nokuguquka: Xa kukho uxinzelelo olunzima lwexesha elide okanye ukungcangcazela okuphezulu okuvela kwizixhobo ezinzima, i-elastic modulus ye-50GPa iqinisekisa ukuba icandelo lidlula kuphela ukuguqulwa okuncinci kwe-elastic. Umzekelo, ekusebenziseni amaqonga okuhlola iibhloko ze-aero enjini, izixhobo zegranite ze-ZHHIMG zinokuxhasa izixhobo zokuhlola ezinobunzima obungaphezulu kweetoni ezi-2, kwaye umahluko wokuthe tyaba ulawulwa ngaphakathi kwe-±0.1μm/m, ukuqinisekisa ukuchaneka komlinganiselo kangangamashumi eminyaka.
Uxinzelelo lwe-buffering ukuthintela ukwaphuka: I-modulus ephezulu ethambileyo ayithethi ukuba izinto zibuthathaka okanye ziqinile. Ulwakhiwo lwekristale yeminerali ngaphakathi kwegranite luyinika amandla ahlukileyo okusasazeka koxinzelelo. Xa iphantsi kwemithwalo yempembelelo, izinto zinokuthintela amandla ngokusebenzisa ukufuduka okuncinci phakathi kweekristale ezincinci, ziphephe ukusasazwa kweentanda okubangelwa kukuxinana koxinzelelo. Umlinganiselo wokwenyani weshishini elithile lokuvelisa i-semiconductor ubonisa ukuba iqonga le-granite le-ZHHIMG alizange lichaphazeleke nakuphi na ukonakala kwesakhiwo emva kokuhlaselwa ngamawakawaka okushukunyiswa koomatshini.
Iindlela Zokusebenza Kwesayensi: Khulula Amandla Okugqibela Ezinto Ezisetyenziswayo
Ukongeza kwiingenelo ezisisiseko zezinto ezisetyenzisiweyo, iteknoloji yokucubungula ngokuchanekileyo kwe-ZHHIMG iphinda ikhuphe amandla okusebenza kwe-granite. Ngokusebenzisa iindlela ezifana nokupholisha kwe-magnetorheological kunye nokugaywa kwe-ion beam, uburhabaxa bomphezulu wezinto bunokwehliswa bube yi-Ra≤0.02μm, kwaye uburhabaxa bunokufikelela kwi-±0.1μm/m. Olu lungiso luchanekileyo alugcini nje ngokunciphisa iziphene zomphezulu kodwa lukwathintela ukuncitshiswa kobomi obubangelwa kukuqhekeka okuncinci, okuvumela ukusebenza kwezinto ukuba kusebenze ngokuzinzileyo ixesha elide.
Ukususela kwisiseko soxinano lwe-3.1g/cm³ ukuya kwinkxaso ye-modulus ye-50GPa, izinto zegranite ze-ZHHIMG zithatha isayensi yezinto njengeyona nto iphambili kwaye zidibanisa ngokunzulu iipropati zendalo kunye netekhnoloji yanamhlanje. Ngobomi benkonzo obungaphezulu kweminyaka engama-30, ayinciphisi nje kuphela iindleko zokutshintshwa kwezixhobo kumashishini, kodwa ikwakhuthaza ukuqhubela phambili ukwenziwa kwemveliso ngokuchanekileyo ukuya ekusebenzeni ixesha elide kunye nokuthembeka okuphezulu, ibe yimodeli "yotyalo-mali oluqala kube kanye, iingenelo zobomi bonke" kwicandelo lemizi-mveliso.
