Kuwunika kwaubwino ndi kuipa kogwiritsa ntchito maziko a granite kuti azitha kukhazikika bwino papulatifomu ya mpweya woyandama.

Choyamba, ubwino wa granite m'munsi
High kuuma ndi otsika matenthedwe mapindikidwe
Kuchulukana kwa granite ndikwambiri (pafupifupi 2.6-2.8 g/cm³), ndipo modulus ya Young imatha kufika 50-100 GPa, kupitilira zida zachitsulo wamba. Kukhazikika kwapamwamba kumeneku kumatha kulepheretsa kugwedezeka kwakunja ndi kusinthika kwa katundu, ndikuwonetsetsa kukhazikika kwa kalozera woyandama mpweya. Panthawi imodzimodziyo, mzere wowonjezera wowonjezera wa granite ndi wotsika kwambiri (pafupifupi 5 × 10⁻⁶/℃), 1/3 yokha ya aloyi ya aluminiyamu, pafupifupi palibe matenthedwe amtundu wa kutentha kwa kutentha kwa kutentha, makamaka oyenera ma laboratories otentha nthawi zonse kapena zochitika za mafakitale ndi kusiyana kwakukulu kwa kutentha pakati pa usana ndi usiku.

Wabwino damping ntchito
Mapangidwe a polycrystalline a granite amapangitsa kuti azikhala ndi mawonekedwe achilengedwe, ndipo nthawi yochepetsera kugwedezeka ndi nthawi 3-5 mwachangu kuposa chitsulo. M'kati mwa makina olondola, amatha kuyamwa bwino kugwedezeka kwapang'onopang'ono monga kuyambika ndi kuyimitsa galimoto, kudula zida, ndikupewa kutengera kumveka kwa malo olondola a nsanja yosuntha (mtengo wake mpaka ± 0.1μm).

Kukhazikika kwanthawi yayitali
Pambuyo pazaka mazana mamiliyoni azaka za geological process zomwe zidapangidwa ndi granite, kupsinjika kwake kwamkati kwatulutsidwa kwathunthu, osati ngati zida zachitsulo chifukwa cha kupsinjika kotsalira komwe kumachitika chifukwa chakusintha pang'onopang'ono. Deta yoyesera imasonyeza kuti kusintha kwa kukula kwa maziko a granite ndi osachepera 1μm / m pazaka 10, zomwe ziri bwino kwambiri kuposa zitsulo zotayidwa kapena zitsulo zopangidwa ndi zitsulo.

Zosagwirizana ndi dzimbiri komanso zosakonza
Granite ku asidi ndi alkali, mafuta, chinyezi ndi zinthu zina zachilengedwe zimakhala ndi kulolerana kwamphamvu, palibe chifukwa chobvala wosanjikiza odana ndi dzimbiri nthawi zonse monga maziko achitsulo. Pambuyo akupera ndi kupukuta, pamwamba roughness angafikire Ra 0.2μm kapena zochepa, amene angagwiritsidwe ntchito mwachindunji monga kubala pamwamba pa mpweya zoyandama kalozera njanji kuchepetsa zolakwa msonkhano.

Chachiwiri, zoperewera za granite maziko
Kukonza zovuta ndi vuto la mtengo
Granite ili ndi kuuma kwa Mohs kwa 6-7, kumafuna kugwiritsa ntchito zida za diamondi pogaya mwatsatanetsatane, kukonza bwino ndi 1/5 yokha yazitsulo. Zovuta dongosolo la dovetail poyambira, mabowo ulusi ndi mbali zina za mtengo processing ndi mkulu, ndi mkombero processing ndi yaitali (mwachitsanzo, processing wa 2m × 1m nsanja amatenga maola oposa 200), chifukwa mu mtengo wonse ndi 30% -50% apamwamba kuposa nsanja zotayidwa aloyi.

Chiwopsezo cha Brittle fracture
Ngakhale mphamvu yopondereza imatha kufika 200-300MPa, kulimba kwa granite ndi 1/10 yokha. Kuphulika kwa Brittle ndikosavuta kuchitika pansi pa zovuta zambiri, ndipo kuwonongeka kumakhala kovuta kukonza. Ndikofunikira kupewa kupsinjika kwapakatikati kudzera pamapangidwe ake, monga kugwiritsa ntchito kusintha kozungulira kozungulira, kuwonjezera kuchuluka kwa malo othandizira, ndi zina.

Kulemera kumabweretsa malire a dongosolo
Kachulukidwe ka granite ndi kuwirikiza 2.5 kuposa aloyi ya aluminiyamu, zomwe zimapangitsa kuti pakhale kulemera kwakukulu kwa nsanja. Izi zimayika chofunika kwambiri pa mphamvu yonyamula katundu wothandizira, ndipo ntchito yowonjezereka ingakhudzidwe ndi mavuto a inertia pazochitika zomwe zimafuna kuyenda mofulumira (monga tebulo laling'ono la lithography).

Zinthu za anisotropy
Kugawa kwa tinthu tating'onoting'ono ta granite zachilengedwe ndikolowera, ndipo kuuma ndi kukulitsa kutentha kwa malo osiyanasiyana kumasiyana pang'ono (pafupifupi ± 5%). Izi zitha kuyambitsa zolakwika zosawerengeka zamapulatifomu olondola kwambiri (monga ma nanoscale positioning), omwe amayenera kukonzedwa ndi kusankha kokhazikika kwa zinthu ndi chithandizo cha homogenization (monga kuwerengera kutentha kwambiri).
Monga chigawo chapakati cha zida zotsogola kwambiri zamafakitale, pulatifomu yolondola ya static pressure air yoyandama imagwiritsidwa ntchito kwambiri popanga semiconductor, kukonza kwa kuwala, kuyeza mwatsatanetsatane ndi magawo ena. Kusankhidwa kwa zinthu zoyambira kumakhudza mwachindunji kukhazikika, kulondola komanso moyo wautumiki wa nsanja. Granite (mwala wachilengedwe), wokhala ndi mawonekedwe ake apadera, wakhala chinthu chodziwika bwino pamapulatifomu oterowo m'zaka zaposachedwa.
