Pankhani yopanga mwatsatanetsatane komanso kafukufuku wapamwamba wa sayansi, kusankha m'munsi kwa nsanja yoyandama ya static pressure air ndiyo chinthu chofunikira kudziwa momwe ntchito yake ikuyendera. Maziko olondola a granite ndi maziko a ceramic ali ndi mawonekedwe awoawo, akuwonetsa zabwino ndi mawonekedwe osiyanasiyana pakukhazikika, kukonza molondola, kukhazikika ndi zina zotero.
Kukhazikika: Kukhazikika kwachilengedwe motsutsana ndi kupanga
Pambuyo pakusintha kwanthawi yayitali kwa geological, granite imalumikizidwa kwambiri ndi quartz, feldspar ndi mchere wina, ndikupanga mawonekedwe owoneka bwino komanso ofanana. Pamaso pa kusokonezedwa kugwedera kunja, monga kugwedera amphamvu kwaiye ntchito zida zazikulu mu msonkhano fakitale, m'munsi mwa granite akhoza bwino kutsekereza ndi attenuate, amene angathe kuchepetsa kugwedera matalikidwe a mwatsatanetsatane malo amodzi kuthamanga mpweya akuyandama nsanja ndi oposa 80%, kupereka khola ntchito maziko nsanja kuonetsetsa yosalala kudziwika kayendedwe mu mkulu-mwatsatanetsatane kudziwika. Mwachitsanzo, mu njira yopangira zida za semiconductor chip, maziko okhazikika a granite amatha kuwonetsetsa kuti zida za chip lithography zikuyenda bwino ndikukwaniritsa mawonekedwe apamwamba kwambiri amitundu ya chip.
Chitsulo cha ceramic chimapangidwa ndi kaphatikizidwe kochita kupanga komanso ukadaulo wapamwamba, ndipo kapangidwe kake kamkati kamakhalanso kofanana komanso kamakhala ndi mawonekedwe abwino akugwedera. Pochita ndi kugwedezeka wamba, imatha kupanga malo okhazikika ogwirira ntchito kuti pakhale nsanja yoyandama ya static pressure air. Komabe, poyang'anizana ndi mphamvu zambiri komanso kugwedezeka kosalekeza, mphamvu yake yochepetsera kugwedezeka ndi yotsika pang'ono poyerekeza ndi maziko a granite, ndipo n'zovuta kuchepetsa kusokonezeka kwa kugwedezeka kwa msinkhu womwewo, womwe ukhoza kukhala ndi zotsatira zina pa kayendedwe kapamwamba kwambiri ka nsanja.
Kusungidwa kolondola: kukulitsa kocheperako kwa zabwino zachilengedwe komanso kuwongolera mochita kulondola
Granite imadziwika chifukwa chochepa kwambiri pakukulitsa kutentha, nthawi zambiri pa 5-7 × 10⁻⁶/℃. M'malo osinthasintha kutentha, kukula kwa maziko a granite kumasintha pang'ono. Pankhani ya zakuthambo, pulatifomu yoyendetsera bwino kwambiri ya magalasi a telescope imalumikizidwa ndi maziko a granite, ngakhale kusiyana kwa kutentha pakati pa usana ndi usiku kuli kofunikira, kumatha kuwonetsetsa kuti kulondola kwa lens kumasungidwa pamlingo wa submicron, kuthandiza akatswiri a zakuthambo kuti agwire zowoneka bwino za matupi akutali.
Zida za Ceramic ndizabwino kwambiri potengera kukhazikika kwamafuta, ndipo kuchuluka kwa matenthedwe azinthu zina zadothi zogwira ntchito kwambiri kumatha kukhala kotsika pafupifupi ziro ndipo kumatha kuyendetsedwa ndendende kudzera mukupanga ndi kukonza. Pazida zina zoyezera bwino kwambiri zoyezera kutentha, maziko a ceramic amatha kukhala osasunthika ngati kutentha kukusintha, kuwonetsetsa kulondola kwa kayendedwe ka mpweya woyandama. Komabe, kukhazikika kwake kwanthawi yayitali pakugwiritsa ntchito koyenera kumakhudzidwa ndi zinthu monga ukalamba wakuthupi ndipo ziyenera kutsimikiziridwa mowonjezereka.
Kukhalitsa: Mwala wachilengedwe wolimba kwambiri komanso zinthu zopanga zopanga dzimbiri
Kuuma kwa granite ndikokwera, kuuma kwa Mohs kumatha kufika 6-7, kukana bwino kuvala. Mu zipangizo sayansi labotale, kaŵirikaŵiri ntchito mwatsatanetsatane malo amodzi kuthamanga mpweya zoyandama nsanja, m'munsi mwake mwachisangalalo akhoza bwino kukana kutayika kwa nthawi yaitali mikangano, poyerekeza ndi m'munsi wamba, akhoza kuwonjezera mkombero kukonza nsanja ndi oposa 50%, kuchepetsa ndalama kukonza zipangizo, ndi kuonetsetsa kupitiriza ntchito kafukufuku wa sayansi. Komabe, zinthu za granite ndizowonongeka, pali ngozi yophulika ikakhudzidwa mwangozi.
Chitsulo cha ceramic sichiri cholimba, komanso chimakhala ndi kukana kwambiri kwa dzimbiri. M'madera akumafakitale komwe kuli chiwopsezo cha dzimbiri la mankhwala, monga mapulatifomu olondola a hydrostatic air flotation mu zida zowunikira mankhwala, maziko a ceramic amakana mpweya wowononga kapena zakumwa, kusunga kukhulupirika kwapamwamba ndi makina kwa nthawi yayitali. M'malo ovuta kwambiri monga chinyezi chambiri, kukhazikika kwa maziko a ceramic ndikwabwinoko kuposa maziko a granite.
Mtengo wopangira ndi zovuta pakukonza: vuto lamigodi la miyala yachilengedwe komanso luso laukadaulo la kaphatikizidwe kochita kupanga.
Migodi ndi mayendedwe a granite zopangira ndizovuta, ndipo kukonza kumafuna zida zapamwamba kwambiri ndiukadaulo. Chifukwa cha kuuma kwake kwakukulu, brittleness, kudula, kugaya, kupukuta ndi njira zina zimakhala zosavuta kugwa, ming'alu, kuchuluka kwa zinyalala, zomwe zimapangitsa kuti pakhale ndalama zambiri zopangira.
Kupanga ma Ceramic base kumadalira kaphatikizidwe kapamwamba komanso ukadaulo wowongolera bwino, kuyambira pakukonza zinthu zopangira, kuumba mpaka ku sintering, sitepe iliyonse iyenera kuyendetsedwa bwino. Kufufuza koyambirira ndi chitukuko ndi ndalama zopangira zida ndi zazikulu, zapamwamba zaukadaulo. Komabe, ndi kukulitsidwa kwa kuchuluka kwa kupanga, mtengowo ukuyembekezeka kuchepetsedwa, ndipo uli ndi kuthekera kotsika mtengo pamapulogalamu apamwamba.
Ponseponse, maziko olondola a granite amachita bwino pakukhazikika komanso kukhazikika kwanthawi zonse, pomwe maziko a ceramic ali ndi mwayi wapadera pakusinthasintha kwa kutentha kwambiri komanso kulimba kwa dzimbiri. Kusankhidwa kwa maziko kuyenera kutengera momwe amagwiritsidwira ntchito, momwe chilengedwe chikuyendera komanso bajeti yamtengo wapatali ya nsanja yoyandama ya static pressure air.
