Kusanthula ubwino ndi kuipa kogwiritsa ntchito maziko a granite kuti pakhale njira yolondola yoyendetsera mpweya wosasunthika.

Choyamba, ubwino wa maziko a granite
Kulimba kwambiri komanso kutentha pang'ono
Kuchuluka kwa granite ndi kwakukulu (pafupifupi 2.6-2.8 g/cm³), ndipo modulus ya Young imatha kufika 50-100 GPa, yoposa kwambiri ya zipangizo wamba zachitsulo. Kulimba kwakukulu kumeneku kumatha kuletsa kugwedezeka kwakunja ndi kusintha kwa katundu, ndikuwonetsetsa kuti chitsogozo choyandama cha mpweya chikhale chosalala. Nthawi yomweyo, coefficient yowonjezereka ya granite ndi yotsika kwambiri (pafupifupi 5×10⁻⁶/℃), 1/3 yokha ya aluminiyamu, pafupifupi palibe kusintha kwa kutentha m'malo osinthasintha kutentha, makamaka yoyenera ma laboratories otentha nthawi zonse kapena malo opangira mafakitale omwe ali ndi kusiyana kwakukulu kwa kutentha pakati pa usana ndi usiku.

Kuchita bwino kwambiri kwa damping
Kapangidwe ka granite ka polycrystalline kamapangitsa kuti ikhale ndi mawonekedwe achilengedwe ochepetsera chinyezi, ndipo nthawi yochepetsera kugwedezeka imakhala yofulumira nthawi 3-5 kuposa ya chitsulo. Pakukonza molondola, imatha kuyamwa bwino kugwedezeka kwa ma frequency monga kuyambitsa ndi kuyimitsa kwa mota, kudula zida, ndikupewa kukhudzidwa ndi kulondola kwa malo oyendetsera nsanja yosuntha (mtengo wamba mpaka ± 0.1μm).

Kukhazikika kwa nthawi yayitali
Pambuyo pa zaka mazana ambiri za njira za geological zomwe zinapanga granite, kupsinjika kwake kwamkati kwatulutsidwa kwathunthu, osati monga zinthu zachitsulo chifukwa cha kupsinjika kotsalira komwe kumachitika chifukwa cha kusintha pang'onopang'ono. Deta yoyesera ikuwonetsa kuti kusintha kwa kukula kwa maziko a granite kuli kochepera 1μm/m mkati mwa zaka 10, zomwe zili bwino kwambiri kuposa za chitsulo chopangidwa kapena zitsulo zolumikizidwa.

Yosagwira dzimbiri komanso yopanda kukonza
Granite mpaka asidi ndi alkali, mafuta, chinyezi ndi zinthu zina zachilengedwe zimakhala ndi kulekerera kwamphamvu, palibe chifukwa chopaka wosanjikiza wotsutsana ndi dzimbiri nthawi zonse monga maziko achitsulo. Pambuyo popera ndi kupukuta, kuuma kwa pamwamba kumatha kufika pa Ra 0.2μm kapena kuchepera, komwe kungagwiritsidwe ntchito mwachindunji ngati malo onyamulira a njanji yoyendetsera mpweya kuti muchepetse zolakwika zosonkhanitsira.

Chachiwiri, zofooka za maziko a granite
Kuvuta kwa kukonza ndi vuto la mtengo
Granite ili ndi kuuma kwa Mohs kwa 6-7, komwe kumafuna kugwiritsa ntchito zida za diamondi popera molondola, kugwira ntchito bwino kwa zinthu zachitsulo ndi 1/5 yokha. Kapangidwe kovuta ka mchira wa dovetail, mabowo opangidwa ndi ulusi ndi zina zomwe zimapangitsa kuti mtengo wake ukhale wokwera, ndipo nthawi yokonza zinthu ndi yayitali (mwachitsanzo, kukonza nsanja ya 2m×1m kumatenga maola opitilira 200), zomwe zimapangitsa kuti mtengo wonse ukhale wokwera ndi 30%-50% kuposa nsanja ya aluminiyamu.

Kuopsa kwa kusweka kwa brittle
Ngakhale mphamvu yokakamiza imatha kufika 200-300MPa, mphamvu yokoka ya granite ndi 1/10 yokha ya iyo. Kusweka kosalimba kumachitika mosavuta mukakhudzidwa kwambiri, ndipo kuwonongeka kumakhala kovuta kukonza. Ndikofunikira kupewa kupsinjika kwambiri kudzera mu kapangidwe kake, monga kugwiritsa ntchito kusintha kozungulira kwa ngodya, kuwonjezera kuchuluka kwa malo othandizira, ndi zina zotero.

Kulemera kumabweretsa zoletsa pa dongosolo
Kuchuluka kwa granite ndi kuwirikiza kawiri kuposa aluminiyamu, zomwe zimapangitsa kuti kulemera konse kwa nsanjayo kukwere kwambiri. Izi zimapangitsa kuti mphamvu yogwiritsira ntchito ikhale yofunikira kwambiri, ndipo magwiridwe antchito amatha kukhudzidwa ndi mavuto a inertia m'malo omwe amafunika kuyenda mwachangu (monga tebulo la lithography wafer).

Zinthu zogwiritsidwa ntchito popanga zinthu
Kugawa kwa tinthu ta mchere mu granite yachilengedwe kumayang'ana mbali, ndipo kuuma ndi kuchuluka kwa kutentha kwa malo osiyanasiyana kumasiyana pang'ono (pafupifupi ± 5%). Izi zitha kuyambitsa zolakwika zosafunikira pa nsanja zolondola kwambiri (monga malo ocheperako), zomwe ziyenera kukonzedwa mwa kusankha zinthu mosamala komanso kuchiza homogenization (monga calcination yokwera kwambiri).
Monga gawo lalikulu la zida zamafakitale zolondola kwambiri, nsanja yoyandama ya mpweya wosasunthika imagwiritsidwa ntchito kwambiri popanga zinthu za semiconductor, kukonza kuwala, kuyeza molondola ndi zina. Kusankha zinthu zoyambira kumakhudza mwachindunji kukhazikika, kulondola komanso moyo wautumiki wa nsanjayo. Granite (granite yachilengedwe), yokhala ndi mawonekedwe ake apadera, yakhala chinthu chodziwika bwino pamaziko a nsanja zotere m'zaka zaposachedwa.
