Nsanja ya granite, monga chida chothandizira kuyeza ndi kukonza molondola, kukonza molondola kumakhudza mwachindunji mtundu wa ntchito. Zotsatirazi zikupereka dongosolo lokonza mwadongosolo lomwe limakhudza kuwongolera chilengedwe, kukonza tsiku ndi tsiku komanso kuwerengera akatswiri kuti zitsimikizire kuti nsanjayo imasunga kulondola kwa nanometer kwa nthawi yayitali.
1. Kuwongolera Zachilengedwe: Pangani chotchinga choteteza molondola
Kusamalira kutentha ndi chinyezi
Kutentha kwa malo ogwirira ntchito kuyenera kukhazikika pa 20±1℃. Kusintha kulikonse kwa 1℃ kumayambitsa kusintha kwa kutentha kwa nsanja ya granite pa 0.5-1μm/m. Dongosolo lotenthetsera lokhazikika likhoza kuyikidwa mu workshop kuti mpweya woziziritsa mpweya usapumire mwachindunji pa nsanjayo.
Chinyezi chiyenera kulamulidwa pakati pa 40% ndi 60%. Chinyezi chochuluka chingayambitse dzimbiri mosavuta pazigawo zachitsulo, pomwe chinyezi chochepa kwambiri chingayambitse kusokonezeka kwa magetsi osasinthasintha poyesa.
Kudzipatula kwa kugwedezeka
Nsanjayo iyenera kusungidwa kutali ndi zinthu zogwedera monga makina opondaponda ndi makina opera. Ndikofunikira kusunga mtunda woposa mamita atatu kuchokera ku zida zogwedera.
Ngati kugwedezeka sikungathe kupewedwa, zoziziritsa mpweya zomwe zimayamwa mpweya zimatha kuyikidwa pansi pa nsanjayo kuti zichepetse kugwedezeka kwa chilengedwe pa kusalala kwa nsanjayo (zomwe zingachepetse kugwedezeka kwakunja ndi zoposa 80%).
2. Kusamalira Tsiku ndi Tsiku: Kuyang'anira mosamala kuyambira kuyeretsa mpaka chitetezo
Kuyeretsa pamwamba
Kuchotsa fumbi: Pukutani pamwamba ndi chikopa cha nswala kapena nsalu yopanda ulusi mbali imodzi tsiku lililonse kuti tinthu ta fumbi (≥5μm) tisakandane papulatifomu. Madontho ouma akhoza kupukutidwa pang'onopang'ono ndi ethanol yosasungunuka (yoyera ≥99.7%). Zosungunulira zamphamvu monga acetone siziyenera kugwiritsidwa ntchito.
Kuchotsa mafuta: Ngati yakhudzana ndi madontho a mafuta, ipukuteni ndi chotsukira chopanda mafuta chochepetsedwa, kenako itsukeni ndi madzi oyeretsedwa ndipo iume bwino kuti mafuta amchere asalowe m'mabowo ang'onoang'ono a nsanjayo.
Chitetezo cha katundu ndi kugundana
Mphamvu yonyamula katundu ya nsanja iyenera kuyendetsedwa mkati mwa 70% ya katundu woyesedwa (mwachitsanzo, pa nsanja ya 1000kg, ndikulimbikitsidwa kuti katunduyo akhale ≤700kg) kuti apewe kusintha kosatha komwe kumachitika chifukwa cha kuchuluka kwa katundu m'deralo.
N'koletsedwa kwambiri kukhudza zida zogwirira ntchito pa nsanja. Mukamagwira zida, valani magolovesi ofewa kuti zinthu zakuthwa zisakanda pamwamba (kukanda kozama kuposa 20μm kudzakhudza kuyeza kwa njira yowunikira).
3. Kulinganiza Akatswiri: Chimake cha kusunga kulondola kwasayansi
Kukhazikitsa kwa kayendedwe ka calibration
Zochitika zachizolowezi zogwiritsira ntchito: Linganizani kamodzi pa kotala iliyonse ndikugwiritsa ntchito laser interferometer kuti muwone kuphwanyika (ndi kulondola kwa ±0.5μm/m).
Kugwiritsa ntchito pafupipafupi kapena malo ovuta: Kuyesa mwezi uliwonse, poyang'ana kwambiri madera omwe kutentha kumakhudza kutentha (monga m'mphepete mwa nsanja pafupi ndi malo otentha).
Kukonza pambuyo pa calibration
Ngati kupotoka kwa flatness kwapezeka (monga > ± 1μm/m), kuyenera kuphwanyidwa ndikukonzedwa ndi katswiri waluso pogwiritsa ntchito ufa wa W1.5 micro-powder. Kudzipukuta nokha ndi sandpaper ndikoletsedwa kwambiri.
Pambuyo poyesa, deta iyenera kulembedwa ndikusungidwa, ndipo njira yochepetsera kulondola kwa nsanja iyenera kukhazikitsidwa kuti idziwiretu zofunikira pakukonza pasadakhale.
4. Kusunga ndi Kuyendera: Pewani kutayika kobisika kolondola
Mfundo zazikulu zosungiramo zinthu kwa nthawi yayitali
Mukasunga, iyenera kuphimbidwa ndi chivundikiro chosanyowa komanso chopanda fumbi. Pansi pake payenera kuthandizidwa ndi mfundo zitatu (malo ochirikiza ali pa 2/9 ya kutalika kwa nsanjayo) kuti apewe kupindika kochitika chifukwa cha mphamvu yokoka (pulatifomu ya mita imodzi ikhoza kugwa ndi 0.3μm chifukwa cha chithandizo cha mfundo imodzi chomwe chimatenga nthawi yayitali).
Sinthani malo a malo othandizira nsanja nthawi zonse (mwezi uliwonse) kuti mupewe kukakamizidwa kwanthawi yayitali.
Ndondomeko yoteteza mayendedwe
Kuyenda patali: Kukulunga ndi thovu loletsa kugwedezeka, kulumikiza mkati mwa chimango cholimba, ndikusunga kuthamanga mkati mwa 2g.
Kuyenda mtunda wautali: Iyenera kupakidwa vacuum ndikudzazidwa ndi nayitrogeni wouma. Ikafika, iyenera kusiyidwa kwa maola 24 mpaka kutentha kufika pamlingo woyenera musanayipatule kuti madzi oundana asakhudze kulondola.
5. Kuneneratu Zolakwika: Njira Zodziwira Mavuto Oyambirira
Kuyang'ana maso: Yang'anani pamwamba nthawi zonse ndi galasi lokulitsa la 40x. Ngati mwapeza mikwingwirima yosalekeza kapena kunyezimira kochepa, izi zitha kusonyeza kuchepa kwa kulondola.
Kuzindikira mawu: Dinani pa nsanja pang'onopang'ono. Ngati mawu amveka mokweza (nthawi zambiri ayenera kukhala omveka bwino), pakhoza kukhala ming'alu yaying'ono mkati. Siyani kugwiritsa ntchito nthawi yomweyo kuti muzindikire.
Kudzera mu dongosolo lokonza ili, nsanja ya granite ya ZHHIMG® imatha kusunga kusalala kwa ±1μm/m kwa zaka 10, komwe ndi nthawi yayitali kuposa nthawi yolondola ya nsanja zomwe sizikusamalidwa bwino. Kafukufuku wasonyeza kuti pambuyo poti fakitale ina ya semiconductor yagwiritsa ntchito njira iyi, kuchuluka kwa kuwerengera kwa nsanja kunachepetsedwa ndi 50%, ndipo ndalama zosamalira pachaka zinapulumutsidwa ndi ma yuan oposa 150,000.
