1. 3.1g/cm³ njupụta: Oke Ọdịdị na-ewulite ntọala na-adịgide adịgide
Njupụta dị elu nke ZHHIMG granite components sitere na nhazi ịnweta ha pụrụ iche na usoro nhazi ala. Granite bụ nke kristal ịnweta dị ka quartz, feldspar na mica jikọtara ọnụ. N'okpuru geological gburugburu ebe obibi nke elu okpomọkụ na elu nrụgide, ndị a mineral kristal na compacted ruo ọtụtụ narị nde afọ, na-akpụ a fọrọ nke nta pore-free ok Ọdịdị (porosity <0.1%). Kọmpat nke a na-enye akụrụngwa nwere uru atọ bụ isi:
Nguzogide iyi pụtara ìhè: Njupụta dị elu pụtara na a na-ahazi atom ndị dị n'elu ihe ahụ, na-eme ka ọ ghara ịdị mfe iyi na ncha n'oge esemokwu ogologo oge ma ọ bụ kọntaktị n'ibu. Dịka ọmụmaatụ, n'iji ụzọ ụgbọ okporo ígwè ziri ezi nke igwe, ihe ndị dị na ZHHIMG granite nwere ike iguzogide ihe karịrị otu nde mmegharị na-emeghachi omume, na-enwe nhụsianya elu nke na-erughị 0.01μm, karịa nke ihe ọdịnala dịka ígwè nkedo. ;

Nguzogide corrosion emelitere: Ọdịdị dị oke egwu na-ewepụta nke ọma mbuso agha nke ihe kemịkal mpụga. Ma ọ bụ acid na alkali reagents, mmanụ ụlọ ọrụ mmepụta ihe ma ọ bụ ikuku iru mmiri, anaghị emetụta nkwụsi ike kemịkalụ nke ZHHIMG granite components. Oke nnabata pH ya bụ 1-14, enwere ike iji ya ogologo oge na gburugburu ebe dị oke egwu na-enweghị mmebi. ;
Nkwụsi ike nke akụkụ dị elu: Ihe ndị dị elu na-enwe mmetụta okpomọkụ dị ala, na-eme ka ọ na-esiri ike ikpo ọkụ ngwa ngwa n'ime akụrụngwa, si otú ahụ na-ebelata nrụgide okpomọkụ nke mgbanwe okpomọkụ kpatara. Ejikọta ya na ọnụọgụ mgbasawanye ọkụ ya dị ka (4-8) × 10⁻⁶ / ℃, a na-achịkwa mgbanwe akụkụ nke akụkụ granite nke ZHHIMG na ọkwa micrometer n'ime oke okpomọkụ nke -40 ℃ ruo 120 ℃, na-eme ka o kwe omume ogologo oge ojiji. ;
Ii. 50GPa Elastic Modulus: Ihe Nlereanya Mechanical nke ijikọ nkwụsi ike na mgbanwe
Igwe ngbanwe na-egosipụta ike ihe nwere ike iguzogide nrụrụ ngbanwe. Module elastic 50GPa nke ZHHIMG granite components na-enyere ha aka igosipụta njirimara nke "ijikọta ike na mgbanwe" mgbe ejiri ibu:
Isi ike dị elu iji guzogide nrụrụ: N'ihu nrụgide dị ogologo oge ma ọ bụ ịma jijiji dị elu site na akụrụngwa dị arọ, modul elastic nke 50GPa na-eme ka a mata na akụkụ ahụ na-enweta nrụrụ dị ntakịrị. Dị ka ọmụmaatụ, na ngwa nke aero engine agụba nyocha nyiwe, na ZHHIMG granite components nwere ike na-akwado nyocha akụrụngwa na-atụ ihe karịrị 2 ton, na flatness mgbanwe na-achịkwa n'ime ± 0.1μm / m, na-ahụ n'ihi na nha nha ruo ọtụtụ iri afọ. ;
Nchekwa nchekwa iji gbochie mgbaji: Igwe ngbanwe dị elu apụtaghị na ihe ahụ na-agbaji agbaji ma ọ bụ sie ike. Ọdịdị kristal ịnweta n'ime granite na-enye ya ikike mgbasa nrụgide pụrụ iche. Mgbe etinyere ya n'ibu mmetụta, ihe ndị ahụ nwere ike chekwaa ike site na ntugharị ntakịrị n'etiti kristal microscopic, na-ezere ịgbasa mgbawa nke nrụgide nrụgide kpatara. Otu ihe nleba anya nke ụlọ ọrụ na-emepụta semiconductor na-egosi n'elu ikpo okwu nke ZHHIMG granite enwebeghị mmebi ọ bụla mgbe emechara ya ọtụtụ iri puku ihe mgbagwoju anya. ;
Iii. Usoro nhazi sayensị sayensị: Mepụta ihe kachasị ike
Na mgbakwunye na uru bara uru nke ihe ahụ, teknụzụ nhazi nke ọma nke ZHHIMG na-ekpughere ikike ịrụ ọrụ nke granite. Site na usoro dị ka magnetorheological polishing na ion beam egweri, elu roughness nke components nwere ike belata na Ra≤0.02μm, na flatness nwere ike iru ± 0.1μm/m. Nhazi nke ọma a dị elu ọ bụghị nanị na-ebelata ntụpọ elu kamakwa ọ na-ezere ogologo ndụ ndụ nke micro-cracks kpatara, na-eme ka arụ ọrụ nke ihe ahụ guzosie ike ruo ogologo oge. ;
Site na njupụta nke 3.1g/cm³ ruo na nkwado modulus nke 50GPa, ZHHIMG granite components na-ewere sayensị ihe dị ka isi ma jikọta ihe ndị sitere n'okike na teknụzụ dị oke ọnụ. Na a ọrụ ndụ nke n'elu 30 afọ, ọ bụghị nanị na budata ebelata-eri nke ngwá nnọchi maka ụlọ ọrụ, ma na-akwalite ọganihu nke nkenke n'ichepụta kwupụta ogologo oge irè na elu pụrụ ịdabere na, na-aghọ a nlereanya nke "otu oge ego, ndụ ogologo uru" na ulo oru ubi. ;
