Kulwakhiwo oluchanekileyo lweqonga lomoya loxinzelelo lwestatic, ukhetho lwesiseko ludlala indima eqinisekileyo ekusebenzeni ngokubanzi kweqonga. Isiseko sokuchaneka kwegranite kunye nesiseko sensimbi esityhidiweyo sineempawu zabo, kwaye kukho ukungafani okucacileyo kwimilinganiselo ephambili efana nokuzinza, ukugcinwa ngokuchanekileyo, ukuqina kunye neendleko.
Okokuqala, ukuzinza: i-dense yendalo kunye nesakhiwo sesinyithi
Emva kwezigidi zeminyaka yotshintsho lwejoloji, igranite idityaniswe ngokusondeleyo nequartz, i-feldspar kunye nezinye iiminerali ukwenza ulwakhiwo oluxineneyo nolufanayo. Ebusweni bokuphazamiseka kwangaphandle, okufana nokungcangcazela okunamandla okuveliswa kukusebenza kwezixhobo ezikhulu kwindawo yokusebenzela yasefektri, isiseko segranite sinokuvala ngokufanelekileyo kwaye sithomalalise ngokuthembela kulwakhiwo lwaso lwekristale oluntsonkothileyo, olunokunciphisa i-vibration amplitude yoxinzelelo oluchanekileyo lwe-static iqonga lomoya elidadayo ngaphezulu kwe-80%, libonelela ngokusebenza okuzinzileyo kwelitye lembombo ngexesha lokuchongwa okanye ukuchongwa okuphezulu kweqonga. Ngokomzekelo, kwinkqubo ye-photolithography yokuvelisa i-chip ye-elektroniki, ukubonakaliswa okuchanekileyo kweepateni ze-chip kuqinisekisiwe.
Isiseko sentsimbi etyhidiweyo sifakwe kwi-iron-carbon alloy, kwaye igraphite yangaphakathi isasazwa kumaphepha okanye kwiinkalo. Nangona inamandla athile okuntywila, ukufana kwayo kolwakhiwo akulunganga xa kuthelekiswa negranite. Xa ujongana noxinzelelo oluphezulu kunye nokungcangcazela okuqhubekayo, kunzima kwisiseko sentsimbi etyhidiweyo ukunciphisa ukuphazamiseka kwe-vibration kwinqanaba eliphantsi elifanayo njengesiseko segranite, esinokukhokelela ekuphambukeni okuncinci ekuhambeni kweqonga elichanekileyo loxinzelelo lwe-static lomoya elidadayo, elichaphazela ukusebenza ngokuchanekileyo kweqonga kwimisebenzi echanekileyo.
Okwesibini, ukugcinwa ngokuchanekileyo: izibonelelo zendalo zokwandiswa okuphantsi kunye nomngeni wokutshintsha kwe-thermal yensimbi.
I-Granite iyaziwa ngokuba yi-coefficient ephantsi kakhulu yokwandiswa kwe-thermal, ngokuqhelekileyo kwi-5-7 × 10⁻⁶/℃. Kwimeko yokuguquguquka kweqondo lobushushu, ubungakanani besiseko sokuchaneka kwegranite kutshintsha kancinci kakhulu. Kwinkalo ye-astronomy, iqonga elichanekileyo le-hydrostatic air float yokulungiswa kakuhle kwelensi yeteleskopu idityaniswe nesiseko segranite, nokuba umahluko weqondo lobushushu phakathi kwemini nobusuku ubalulekile, inokuqinisekisa ukuba ukuchaneka kokubeka ilensi kugcinwa kwinqanaba le-submicron, inceda izazi ngeenkwenkwezi ukuba zibambe amandla afihlakeleyo wemizimba ekude.
I-coefficient yokwandiswa kwe-thermal yensimbi etyhidiweyo iphezulu, ngokubanzi i-10-20 × 10⁻⁶/℃. Xa iqondo lobushushu litshintsha, ubungakanani besiseko sentsimbi etyhidiweyo butshintsha ngokucacileyo, nto leyo ekulula ukubangela ukuguqulwa kwe-thermal yeqonga elichanekileyo loxinzelelo lwe-static lomoya odadayo, okukhokelela ekunciphiseni kokuchaneka kwentshukumo yeqonga. Kwinkqubo yokugaya i-lens ye-optical optical-sensitive-sensitive, ukuguqulwa kwesiseko sensimbi etyhidiweyo phantsi kwefuthe lokushisa kunokubangela ukuphambuka kokuchaneka kokugaya kwe-lens ngaphaya koluhlu oluvumelekileyo kwaye kuchaphazele umgangatho welensi.
Okwesithathu, ukuqina: ubunzima obuphezulu belitye lendalo kunye nokukhathala kwesinyithi
Ubunzima be-Granite buphezulu, ubunzima be-Mohs bunokufikelela kwi-6-7, ukuchasana kakuhle kokugqoka. Kwilabhoratri yezenzululwazi yezinto ezisetyenziswa rhoqo, iqonga lokudada lomoya oluchanekileyo oluchanekileyo, isiseko sayo segranite sinokuxhathisa ngempumelelo ilahleko yexesha elide, xa kuthelekiswa nesiseko esiqhelekileyo, inokwandisa umjikelo wokugcinwa kweqonga ngaphezulu kwama-50%, ukunciphisa iindleko zokugcina izixhobo, kunye nokuqinisekisa ukuqhubeka komsebenzi wophando lwezenzululwazi. Nangona kunjalo, izinto zegranite zincinci, kwaye kukho umngcipheko wokuqhekeka xa kuchaphazeleka ngengozi.
Isiseko sentsimbi sinobunzima obuthile kwaye akulula ukuphuka xa sithwala amandla athile empembelelo. Nangona kunjalo, kwinkqubo ye-high frequency reciprocating movement of precision static pressure air floating platform for an long time, intsimbi ephosiweyo ithanda ukudinwa umonakalo, okubangela utshintsho kwisakhiwo sangaphakathi, esichaphazela ukuchaneka kwentshukumo kunye nokuzinza kweqonga. Ngexesha elifanayo, isinyithi esityhidiweyo sixhomekeke kwi-rust kunye ne-corrosion kwiindawo ezinomswakama, ukunciphisa ukuqina kwayo, ngokuchaseneyo, isiseko se-granite ekuchaseni ukubola singcono.
Okwesine, iindleko zokuvelisa kunye nobunzima bokucubungula: ukumbiwa kwamatye endalo kunye nemingeni yokucubungula kunye nenkqubo yokuphosa isinyithi
Ukumbiwa kunye nokuthuthwa kwezixhobo zegranite zintsonkothile, kwaye ukusetyenzwa kufuna izixhobo eziphezulu kakhulu kunye nobuchwepheshe. Ngenxa yokuqina kwayo okuphezulu, i-brittleness, ukusika, ukuguba, ukugulisa kunye nezinye iinkqubo zivame ukudilika, iintanda, isantya esiphezulu se-scrap, okubangela iindleko eziphezulu zokuvelisa.
Isiseko sentsimbi senziwa ngenkqubo yokuphosa ekhulileyo, umthombo obanzi wemathiriyeli ekrwada kunye nexabiso eliphantsi. Ngokusebenzisa isikhunta sinokufikelela kwimveliso yobuninzi, ukusebenza kakuhle kwemveliso. Nangona kunjalo, ukuze kufezekiswe ukuchaneka okuphezulu kunye nokuzinza njengesiseko segranite, inkqubo yokuphosa kunye neemfuno zasemva kokulungiswa zingqongqo kakhulu, zifuna ukuchaneka komatshini kunye nonyango lokuguga, njl., kwaye iindleko ziya kunyuka kakhulu.
Isishwankathelo, isiseko sokuchaneka kwegranite sineenzuzo ezibalulekileyo kwimiba yesicelo seqonga elichanekileyo loxinzelelo lwe-static air float efuna ukuchaneka okuphezulu, ukuzinza kunye nokumelana nokunxiba; Isiseko sensimbi esityhidiweyo sineenzuzo ezithile kwiindleko kunye nokuqina, kwaye zifanelekile kwizihlandlo apho iimfuno zokuchaneka zincinci, ukuphishekela ukusetyenziswa kweendleko kunye ne-vibration kunye neqondo lokushisa lizinzile.
