Kodi Mukunyalanyaza Kulondola kwa Nanometer Yanu? Udindo Wofunika Kwambiri wa Kusamalira ndi Kukonza Granite Surface Plate Yoyenera

Mbale ya pamwamba pa granite ndiye malo ofunikira kwambiri pakuwunika kwa zinthu. Komabe, kukhulupirika kwa chizindikiro chimenecho—kaya ndi chitsanzo chowunikira chokhazikika kapena chinthu cholondola kwambiri monga mbale yakuda ya granite Series 517—kumadalira chisamaliro chokhwima. Kwa akatswiri a za metrology ndi akatswiri owongolera khalidwe, mafunso awiri akadali ofunika kwambiri: Kodi chotsukira bwino kwambiri cha granite pamwamba pa mbale ndi chiyani, ndipo njira yofunika kwambiri yowunikira pamwamba pa mbale ya granite iyenera kuchitika kangati?

Malo ozungulira bwino a pamwamba pa mbaleyo amakhala osavuta kuipitsidwa ndi fumbi la chilengedwe, zotsalira za mafuta, ndi tinthu tating'onoting'ono tomwe timayatsidwa kuchokera ku zinthu zogwirira ntchito. Zonyansazi, ngati sizikusamalidwa, zimalowa mu granite yokhala ndi ming'alu, zomwe zimapangitsa kuti iwonongeke msanga komanso kuti isasweke. Kugwiritsa ntchito njira yoyeretsera yolakwika—monga zochotsera mafuta m'mafakitale wamba kapena mankhwala okhala ndi tinthu tating'onoting'ono toyamwa—kungawononge malowo mwachangu kuposa momwe amagwiritsidwira ntchito. Ichi ndichifukwa chake kusankha chotsukira granite pamwamba pa mbale sikungatheke kukambirana.

Chotsukira bwino kwambiri cha granite surface plate ndi chomwe chinapangidwa kuti chinyamule ndikuyimitsa tinthu tating'onoting'ono popanda kusiya filimu kapena kupukuta granite. Akatswiri nthawi zonse ayenera kufunsa katswiri wotsukira granite surface plate SDS (Safety Data Sheet) kuti atsimikizire kuti chinthucho chili ndi pH-neutral, sichili ndi poizoni, komanso chilibe mankhwala osungunuka achilengedwe (VOCs) omwe angasiye zotsalira. Chotsukira chapamwamba chimathandiza kuchotsa zodetsa ndipo, chikaphatikizidwa ndi nsalu yoyera, yopanda utoto, chimabwezeretsa pamwamba pa chinthucho kuti chikhale chokonzeka kuyeza, ndikusunga mwachindunji kulondola kwa mbaleyo. ZHHIMG®, pozindikira kuti magwiridwe antchito abwino kwambiri amayamba ndi malo oyera, akugogomezera gawo lofunika kwambiri ngati gawo la malangizo ake athunthu okhudza moyo wa chinthucho.

Kupatula kuyeretsa tsiku ndi tsiku, kutsimikiziranso nthawi ndi nthawi kuti mbaleyo ndi yopyapyala—kulinganiza pamwamba pa mbale ya granite—n'kofunika kwambiri. Ngakhale pakakhala nyengo yabwino, kusinthasintha kwa chilengedwe, kutentha, ndi njira zosapeŵeka zogwiritsira ntchito zimapangitsa kuti pamwamba pakhale kuphwanyika pang'ono. Ndondomeko yowunikira iyenera kutsimikiziridwa kutengera mtundu wa mbaleyo (monga, mbale za Giredi 00 zimafuna kuyang'aniridwa pafupipafupi kuposa Giredi B) ndi kuchuluka kwa momwe zimagwiritsidwira ntchito.

Mukafuna kuwerengera mbale ya granite pamwamba pa matabwa pafupi ndi ine, onetsetsani kuti wopereka chithandizo akugwiritsa ntchito zida zotsatizana motsatira miyezo ya dziko, monga ma interferometer a laser otsatizana ndi ma level amagetsi, monga zida zolondola kwambiri zomwe zimagwiritsidwa ntchito ndi magulu a akatswiri a ZHHIMG®. Kuwerengera kwenikweni kumapitirira kufufuza kosavuta; kumaphatikizapo kukonzanso kwa akatswiri kuti abwezeretse mbaleyo ku kulekerera kwake koyambirira kovomerezeka, njira yomwe imafuna luso lapadera lomwe akatswiri aluso a ZHHIMG® achita kwa zaka zambiri.

Kuphatikiza apo, chitetezo panthawi yomwe simugwiritsa ntchito n'chofunika kwambiri. Chophimba cha granite pamwamba pake—chopangidwa ndi chinthu chokhuthala, chosawononga—chimagwira ntchito ziwiri: chimateteza pamwamba pake ku zinthu zodetsa mpweya ndipo chimagwira ntchito ngati chotetezera kutentha pang'ono, kuteteza mbaleyo ku kusintha kwadzidzidzi kwa kutentha. Njira yosavuta imeneyi imachepetsa kwambiri ntchito yoyeretsa ndikuwonjezera nthawi pakati pa ntchito zofunika zobwezeretsanso.

Pomaliza, kukwaniritsa ndi kusunga kulondola kwambiri ndi kudzipereka komwe kumapitirira pa kugula koyamba mbale yapamwamba kwambiri. Mwa kusankha mosamala chotsukira mbale ya granite yoyenera, kutsatira ndondomeko yokhazikika yowunikira mbale ya granite, komanso kugwiritsa ntchito njira zoyenera zodzitetezera, opanga amaonetsetsa kuti maziko awo a metrology akhalabe malo odalirika komanso ofunikira padziko lonse lapansi kwa zaka zikubwerazi.
