Mu ma laboratories apamwamba kwambiri padziko lonse lapansi, kaya ndi kuzindikira zipangizo za nanoscale, kuwunika molondola kwa zigawo zowunikira, kapena kuyeza kwa microstructure ya ma semiconductor chips, pali zofunikira kwambiri pa kulondola ndi kukhazikika kwa zizindikiro zoyezera. Granite straightedge, yokhala ndi magwiridwe antchito abwino kwambiri, yakhala chisankho choyamba cha ma laboratories ambiri. Poyerekeza ndi malo owonetsera achitsulo chachikhalidwe, kukhazikika kwake kolondola kumatha kukwezedwa mpaka 300%, zomwe zimachokera ku umboni wozama wasayansi ndi kutsimikizira kothandiza.
1. Katundu wa zinthu ndi amene amatsimikizira kulondola kwa zinthu
Chitsulo chopangidwa ndi chitsulo, monga chinthu chodziwika bwino cha pamwamba, ngakhale chili ndi kulimba kwake, chili ndi zolakwika zake. Kuchuluka kwa kutentha kwake ndi pafupifupi 12 × 10⁻⁶/℃. Pansi pa kusintha kwa kutentha komwe kumachitika mu labotale (monga kusiyana kwa kutentha kwa 5℃ komwe kumachitika chifukwa cha kuyambika ndi kuyimitsidwa kwa ma air conditioner), pamwamba pa chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo cha mita imodzi kutalika kumatha kusintha mawonekedwe a 60μm. Kuphatikiza apo, pali kapangidwe ka graphite mkati mwa chitsulo chopangidwa ndi chitsulo. Kugwiritsa ntchito kwa nthawi yayitali kumakhala ndi kupsinjika, zomwe zimapangitsa kuti pang'onopang'ono kusalala kwa malo ofunikira kuchepe. Mtundu uwu wa kusintha kwa kutentha ndi kusintha kwa kapangidwe kake kungayambitse kusintha kwadongosolo mu deta yoyezera, zomwe zimakhudza kwambiri kulondola kwa zotsatira zoyesera.
Mosiyana ndi zimenezi, kuchuluka kwa kutentha kwa granite straightedge ndi (4-8) ×10⁻⁶/℃, komwe ndi kochepera gawo limodzi mwa magawo atatu a chitsulo chopangidwa. Pansi pa kusiyana komweko kwa kutentha kwa 5℃, kusintha kwa kukula kwa granite straightedge yautali wa mita imodzi ndi 20-40 μm yokha. Granite imapangidwa ndi crystallization ya mchere monga quartz ndi feldspar. Ili ndi kapangidwe kolimba komanso kofanana ndipo palibe vuto la kupsinjika kwamkati. Pambuyo pa zaka mabiliyoni ambiri za njira za geological, granite yakalamba mwachilengedwe ndipo sidzasintha ngati chitsulo chopangidwa pakapita nthawi, kuonetsetsa kuti malo ofunikira akhazikika kwa nthawi yayitali kuchokera ku chinthucho.
Chachiwiri, ukadaulo wokonza zinthu umakwaniritsa kulondola kwambiri
Pakukonza malo ofotokozera chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo, chifukwa cha kuchepa kwa zinthu zomwe zili mkati mwake, kulondola kwa kusalala nthawi zambiri kumatha kufika ± 5-10 μm. Kuphatikiza apo, pamwamba pa chitsulo chopangidwa ndi ...
Granite straightedge imagwiritsa ntchito ukadaulo wopukutira wolondola kwambiri ndipo imaphatikizidwa ndi ukadaulo wapamwamba wowongolera manambala. Kusalala kwake kumatha kulamulidwa mkati mwa ± 1-3 μm, ndipo zinthu zina zapamwamba zimatha kufika ± 0.5μm. Kuuma kwake pamwamba kumafika 6 mpaka 7 pa sikelo ya Mohs, ndipo kukana kwake kutopa ndi kuwirikiza katatu mpaka kasanu kuposa chitsulo chopangidwa. Sichikanda kapena kusweka mosavuta. Ngakhale mutagwiritsa ntchito nthawi yayitali, kulondola kwa pamwamba pa granite straightedge kumatha kukhalabe kokhazikika, kuchotsa kufunikira kowunikira ndi kukonza pafupipafupi, kuchepetsa kwambiri mtengo wogwiritsidwa ntchito ndi labotale komanso nthawi.
III. Kusinthasintha kwa chilengedwe kumatsimikizira kuti muyeso wake ndi wokhazikika
Malo ochitira kafukufuku ndi ovuta komanso osinthika. Zinthu monga chinyezi, kugwedezeka, ndi kusokonezeka kwa ma elekitiromagineti zonse zimatha kukhudza kulondola kwa muyeso. Malo ofotokozera chitsulo chopangidwa ndi ...
Granite straightedge ndi chinthu chosakhala chachitsulo, chosakhala ndi maginito komanso chosayendetsa magetsi, ndipo sichingasokoneze zida zamagetsi. Kuchuluka kwake koyamwa madzi ndi kochepera 0.1%, ndipo kumathabe kugwira ntchito bwino pamalo omwe ali ndi chinyezi chambiri. Kuphatikiza apo, mphamvu zapadera za granite zimatha kuyamwa bwino kugwedezeka kwa chilengedwe ndikuchepetsa kusokonezeka kwakunja. Mwachitsanzo, mu labotale pafupi ndi zida zazikulu ndi zida, granite straightedge imatha kuchepetsa mphamvu yopitilira 90% mkati mwa sekondi imodzi, pomwe pamwamba pa chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chimatenga masekondi atatu mpaka asanu. Izi zimathandiza granite straightedge kupereka chizindikiro chokhazikika choyezera ngakhale m'malo ovuta.
Zinayi. Deta yeniyeni imatsimikizira ubwino wa magwiridwe antchito
Laboratory yodziwika bwino yapadziko lonse lapansi ya semiconductor idachitapo mayeso oyerekeza kwa nthawi yayitali pa malo owunikira chitsulo chopangidwa ndi granite: Pa nthawi yoyesera yomwe idatenga masiku 30 ndikupitilira maola 8 tsiku lililonse, cholakwika choyezera cha zida zogwiritsa ntchito malo owunikira chitsulo chopangidwa ndi granite chinafika ±45μm. Zipangizo zogwiritsa ntchito granite straightedge zili ndi cholakwika choyezera cha ±15μm yokha, ndipo kusintha kwa kukhazikika kolondola kuli kokwera kufika 300%. Zotsatira zoyesera zofananazi zatsimikiziridwa mobwerezabwereza m'ma laboratories apamwamba m'magawo osiyanasiyana monga sayansi ya zida ndi uinjiniya wa optical, zomwe zikuwonetsanso kusasinthika kwa granite straightedge pakuyesa kolondola kwambiri.
Pomaliza, granite straightedge yapambana kwambiri pamwamba pa chitsulo chosungunuka chifukwa cha ubwino wake katatu wa zinthu zakuthupi, ukadaulo wokonza zinthu komanso kusinthasintha kwa chilengedwe. Kusintha kwake kwa 300% pakukhazikika kolondola sikungopereka muyezo wodalirika wa ma laboratories komanso kumayika maziko olimba a chitukuko cha kafukufuku wasayansi wamakono komanso ukadaulo wopanga zinthu molondola. Ichi ndiye chifukwa chachikulu chomwe ma laboratories apamwamba padziko lonse lapansi ali ndi ma granite straightedges osankhidwa.
