Pazinthu zopanga zinthu zapamwamba kwambiri komanso uinjiniya wolondola, moyo wautumiki wa zigawo za zida umagwirizana mwachindunji ndi kukhazikika kwa kupanga ndi ndalama zogwirira ntchito. ZHHIMG zida za granite, zokhala ndi kachulukidwe kopitilira muyeso wa 3.1g/cm³ komanso zotanuka modulus ya 50GPa, zadutsa malire a zida zachikhalidwe, ndikukhala ndi moyo wautumiki wazaka zopitilira 30 ndikukhala "chizindikiro cha moyo wautali" pamafakitale. Mfundo zasayansi zomwe zimachokera kumbuyo zimawulula kugwirizana kwakukulu pakati pa magwiridwe antchito ndi kulimba. ku
1. 3.1g/cm³ kachulukidwe: Kapangidwe kakakulu kamamanga maziko olimba
Kuchulukana kwakukulu kwa zigawo za granite za ZHHIMG zimachokera ku mapangidwe awo apadera a mchere komanso mapangidwe a geological. Granite imapangidwa makamaka ndi makristasi amchere monga quartz, feldspar ndi mica kuphatikiza kwambiri. Pansi pa chilengedwe cha kutentha kwambiri komanso kuthamanga kwambiri, mcherewu wasungunuka ndikuphatikizana kwazaka mazana mamiliyoni ambiri, ndikupanga mawonekedwe owoneka bwino opanda pore (porosity <0.1%). Kuphatikizika uku kumapereka zigawo zomwe zili ndi zabwino zitatu zazikulu:
Kukaniza Kuvala Kwapadera: Kuchulukana kwakukulu kumatanthauza kuti maatomu omwe ali pamalopo amakonzedwa bwino, zomwe zimapangitsa kuti zisavalidwe komanso kukandana pakakangana kwanthawi yayitali kapena kukhudzana ndi makina. Mwachitsanzo, pakugwiritsa ntchito njanji zowongolera zida zamakina, zida za granite za ZHHIMG zimatha kupirira kusuntha kopitilira miliyoni miliyoni, ndikutayika kwapamwamba kosakwana 0.01μm, kupitilira zida zakale monga chitsulo choponyedwa. ku
Kulimbana ndi dzimbiri: Kuchulukana kwake kumalekanitsa bwino kuukira kwa zinthu zakunja za mankhwala. Kaya ndi asidi ndi ma reagents a alkali, madontho amafuta am'mafakitale kapena mpweya wonyowa, kukhazikika kwamankhwala kwa ZHHIMG zida za granite sikukhudzidwa. Mtundu wake wolekerera pH ndi 1-14, ndipo ukhoza kugwiritsidwa ntchito kwa nthawi yayitali m'malo ovuta kwambiri popanda dzimbiri. ku
Kukhazikika kwapang'onopang'ono: Zida zamphamvu kwambiri zimakhala ndi matenthedwe otsika, zomwe zimapangitsa kuti zikhale zovuta kuti kutentha kumabalalike mwachangu mkati mwa chigawocho, potero kumachepetsa kupsinjika kwa kutentha komwe kumachitika chifukwa cha kusintha kwa kutentha. Kuphatikizidwa ndi coefficient yake yowonjezera kutentha yotsika ngati (4-8) × 10⁻⁶/℃, kusintha kwapang'onopang'ono kwa zigawo za granite za ZHHIMG nthawi zonse kumayang'aniridwa pamlingo wa micrometer mkati mwa kutentha kwa -40 ℃ mpaka 120 ℃, kuonetsetsa kuti kugwiritsidwa ntchito kwa nthawi yaitali kukhale kolondola. ku
Ii. 50GPa Elastic Modulus: Chodabwitsa Chamakina Chophatikiza Kukhazikika ndi Kusinthasintha
Elastic modulus imawonetsa kuthekera kwazinthu kukana kusinthika kwa zotanuka. 50GPa zotanuka modulus ya ZHHIMG zida za granite zimawathandiza kuwonetsa mawonekedwe a "kuphatikiza kulimba ndi kusinthasintha" akalemedwa:
Kukhazikika kwakukulu kuti muthe kukana mapindikidwe: Poyang'anizana ndi kukakamizidwa kwanthawi yayitali kapena kugwedezeka kwamphamvu kuchokera ku zida zolemera, modulus zotanuka za 50GPa zimawonetsetsa kuti gawolo limangowonongeka pang'ono. Mwachitsanzo, pakugwiritsa ntchito nsanja zoyendera tsamba la injini ya aero, zida za granite za ZHHIMG zimatha kuthandizira zida zowunikira zolemera matani awiri, ndipo kusinthasintha kwake kumayendetsedwa mkati mwa ± 0.1μm/m, kuwonetsetsa kuyeza kwake kwazaka zambiri. ku
Kupanikizika kwapang'onopang'ono kuti mupewe kusweka: Modulus yotalikirana kwambiri sikutanthauza kuti zinthuzo ndi zolimba kapena zolimba. Mapangidwe a ma kristalo amchere mkati mwa granite amamupatsa mphamvu yapadera yobalalika. Zikachulukidwa ndi katundu, zidazo zimatha kusungitsa mphamvu kudzera pakusuntha pang'ono pakati pa makhiristo ang'onoang'ono, kupewa kufalitsa ming'alu chifukwa cha kupsinjika. Muyezo weniweni wamakampani opanga ma semiconductor akuwonetsa kuti nsanja ya ZHHIMG yonyamulira granite sinawonongeke chifukwa chogwedezeka ndi masauzande ambiri. ku
Iii. Njira Zopangira Sayansi: Tsegulani Kuthekera Kwambiri kwazinthu
Kuphatikiza pa zabwino zomwe zidalipo, ukadaulo wa ZHHIMG wotsogola kwambiri umawonetsanso kuthekera kwa granite. Kupyolera mu njira monga magnetorheological kupukuta ndi ion mtengo akupera, pamwamba roughness wa zigawo zikuluzikulu akhoza kuchepetsedwa Ra≤0.02μm, ndi flatness akhoza kufika ± 0.1μm/m. Kukonzekera kolondola kwambiri kumeneku sikungochepetsa zolakwika zapamtunda komanso kumapewa kuchepetsedwa kwa moyo komwe kumachitika chifukwa cha ming'alu yaying'ono, zomwe zimapangitsa kuti zinthuzo zizigwira ntchito kwa nthawi yayitali. ku
Kuchokera pa kachulukidwe maziko a 3.1g/cm³ kupita ku modulus thandizo la 50GPa, ZHHIMG zida za granite zimatengera sayansi yazinthu ngati maziko ndikuphatikiza kwambiri zachilengedwe ndiukadaulo wapamwamba kwambiri. Ndi moyo utumiki wa zaka zoposa 30, izo osati kwambiri kuchepetsa mtengo wa zipangizo m'malo mabizinesi, komanso amalimbikitsa patsogolo kupanga mwatsatanetsatane kwa mphamvu yaitali ndi kudalirika mkulu, kukhala chitsanzo cha "ndalama kamodzi, phindu moyo" m'munda mafakitale. ku
