Mu bijyanye n'inganda zigezweho n'ubuhanga bugezweho, igihe cyo gukora ibikoresho gifitanye isano itaziguye n'uburyo ibikoresho bihagaze neza n'ikiguzi cyo gukora. Ibice bya granite bya ZHHIMG, bifite ubucucike buri hejuru cyane bwa 3.1g/cm³ na modulus nziza ya 50GPa, byarenze imipaka y'ibikoresho gakondo, bigera ku gihe cyo gukora cy'imyaka irenga 30 kandi biba "igipimo cyo kuramba" mu nganda. Amahame y'ubumenyi bw'ibikoresho inyuma yabyo agaragaza isano iri hagati y'imikorere n'uburambe.
1. Ubucucike bwa 3.1g/cm³: Inyubako nini yubaka urufatiro rurambye
Ubucucike bwinshi bw'ibice bya granite bya ZHHIMG buturuka ku miterere yabyo yihariye y'amabuye y'agaciro n'uburyo bwo gushinga imiterere y'ubutaka. Granite igizwe ahanini n'amabuye y'agaciro nka quartz, feldspar na mica bihujwe cyane. Mu rwego rw'ibidukikije by'ubushyuhe bwinshi n'umuvuduko mwinshi, aya mabuye y'agaciro yamaze imyaka amagana ahinduka kristali kandi akomera, akora imiterere y'ubucucike butagira imyenge myinshi (porosity < 0.1%). Ubu bucucike buha ibice ibyiza bitatu by'ingenzi:
Ubudahangarwa budasanzwe bwo kwangirika: Ubucucike bwinshi busobanura ko atome ziri ku buso bw'ibikoresho zitondetse neza, bigatuma zidasaza cyangwa ngo zikubitwe mu gihe cy'igihe kirekire cyangwa gukoranaho n'imashini. Urugero, mu ikoreshwa ry'ibyuma biyobora ibyuma by'imashini, ibice bya granite bya ZHHIMG bishobora kwihanganira ingendo zirenga miliyoni zisubiranamo, hamwe n'igihombo cy'ubuso kiri munsi ya 0.01μm, kirenze kure icy'ibikoresho gakondo nk'icyuma gishongeshejwe.
Ubudahangarwa bw’ubukonje: Imiterere y’ubukonje igabanya byinjira mu bintu byo hanze bya shimi. Byaba ari aside na alkali, ibizinga bya peteroli mu nganda cyangwa umwuka utose, ubudahangarwa bw’ibinyabutabire bya ZHHIMG granite ntabwo bugira ingaruka. Ingano ya pH yayo ni 1-14, kandi ishobora gukoreshwa igihe kirekire ahantu habi cyane hatabayeho ubukonje.
Gukomera mu buryo buhanitse: Ibikoresho bifite ubucucike bwinshi bifite ubushobozi buke bwo gutwara ubushyuhe, bigatuma ubushyuhe butiyongera vuba mu gice, bityo bikagabanya uburemere bw'ubushyuhe buterwa n'impinduka z'ubushyuhe. Hamwe n'uburyo bwo kwaguka kw'ubushyuhe buri hasi nka (4-8) × 10⁻⁶/℃, impinduka z'ibice bya granite bya ZHHIMG zigenzurwa buri gihe ku rugero rwa mikorometero mu bushyuhe buri hagati ya -40 ℃ na 120 ℃, bigamije kwemeza ko ikoreshwa ry'igihe kirekire ari ukuri.
Ii. 50GPa Elastic Modulus: Igitangaza cya Mekaniki cyo guhuza Uburimbane n'Ubworoshye
Modulus ya elastic igaragaza ubushobozi bw'ikintu mu kurwanya impinduka za elastic. Modulus ya elastic ya 50GPa y'ibice bya granite bya ZHHIMG ibafasha kugaragaza imiterere yo "guhuza uburimbane n'ubworoherane" iyo bashyizwe mu biremereye:
Uburimbane bwinshi bwo kurwanya impinduka: Mu gihe cy'umuvuduko mwinshi cyangwa guhindagura kw'ibikoresho biremereye igihe kirekire, modulus ya elastic ya 50GPa ituma igice kigira impinduka ntoya cyane. Urugero, mu ikoreshwa ry'ibikoresho byo kugenzura ibyuma bya moteri, ibice bya granite bya ZHHIMG bishobora gushyigikira ibikoresho byo kugenzura bipima toni zirenga 2, kandi ihindagurika ry'ubugari rigenzurwa muri ± 0.1μm/m, bigatuma ibipimo biba byiza mu gihe cy'imyaka ibarirwa muri za mirongo.
Guhagarika kugira ngo hirindwe kuvunika: Uburyo bworoshye bwo gukurura ntibusobanura ko ibikoresho bicika intege cyangwa bikomeye. Imiterere ya kristu iri muri granite iha ubushobozi bwo gukwirakwiza stress. Iyo ishyizwe mu bintu biremereye, ibice bishobora guhagarika ingufu binyuze mu kwimuka guto hagati ya kristu ntoya, birinda gukwirakwira kw'imivuniko iterwa no gukomereka. Igipimo nyacyo cy'ikigo kimwe cy'inganda zikora ibikoresho bya semiconductor kigaragaza ko urubuga rwa ZHHIMG granite rutigeze rwangirika nyuma yo gukomeretswa n'ibintu ibihumbi mirongo.
Iii. Ubuhanga mu Gutunganya Ibikoresho mu Buhanga: Kuramo Ubushobozi Busesuye bw'Ibikoresho
Uretse ibyiza by’ibikoresho, ikoranabuhanga rya ZHHIMG ryo gutunganya neza cyane rirushaho gukuramo ubushobozi bw’umusaruro wa granite. Binyuze mu buryo nka magnetorheological polishing na ion beam grinding, ubukana bw’ibice bishobora kugabanuka kugera kuri Ra≤0.02μm, kandi ubugari bushobora kugera kuri ±0.1μm/m. Ubu buryo bwo gutunganya neza cyane ntibugabanya gusa inenge zo ku buso ahubwo bunarinda ubukana bw’igihe kirekire buterwa n’udusimba duto, bigatuma imikorere y’ibikoresho ikomeza gukoreshwa neza mu gihe kirekire.
Kuva ku rufatiro rw'ubucucike bwa 3.1g/cm³ kugeza ku nkunga ya modulus ya 50GPa, ibice bya granite bya ZHHIMG bifata siyansi y'ibikoresho nk'ishingiro kandi bigahuza cyane imiterere karemano n'ikoranabuhanga rigezweho. Bifite ubuzima bw'imyaka irenga 30, ntibigabanya gusa ikiguzi cyo gusimbuza ibikoresho ku bigo, ahubwo binateza imbere iterambere ry'inganda zikora neza mu rwego rwo kugira umusaruro urambye no kwizerwa cyane, bikaba icyitegererezo cy'"ishoramari rimwe, inyungu z'ubuzima bwose" mu rwego rw'inganda.
