Kwinkalo yokwenziwa ngokuchanekileyo kunye nophando oluphambili lwezenzululwazi, ukhetho olusisiseko lweqonga loxinzelelo lwe-static oluchanekileyo lomoya odadayo yeyona nto iphambili yokumisela ukusebenza kwayo. Isiseko se-granite esichanekileyo kunye nesiseko se-ceramic sineempawu zabo, ezibonisa iingenelo ezahlukeneyo kunye neempawu ekuzinzeni, ukugcinwa ngokuchanekileyo, ukuhlala njalo njalo.
Uzinzo: Ubume bendalo xa kuthelekiswa nokwenziwa
Emva kotshintsho olude lwe-geological, i-granite idityaniswe ngokusondeleyo yi-quartz, i-feldspar kunye nezinye iiminerali, zenza isakhiwo esixineneyo nesifanayo. Ebusweni bokuphazamiseka kokungcangcazela kwangaphandle, okufana nokungcangcazela okuqinileyo okuveliswe kukusebenza kwezixhobo ezinkulu kwindawo yokusebenzela yasefektri, isiseko segranite sinokubhloka ngokufanelekileyo kwaye sithomalalise, esinokunciphisa i-vibration amplitude yoxinzelelo oluchanekileyo lwe-static iqonga lomoya elidadayo ngaphezulu kwe-80%, libonelela ngesiseko esizinzileyo sokusebenza kwiqonga lokuqinisekisa ukubonwa komgangatho ochanekileyo okanye ukuchongwa okuphezulu. Ngokomzekelo, kwinkqubo ye-lithography yokwenziwa kwe-chip ye-semiconductor, isiseko se-granite esizinzile sinokuqinisekisa ukusebenza ngokuchanekileyo kwezixhobo ze-chip lithography kunye nokufezekisa ukuchaneka okuphezulu kweempawu ze-chip.
Isiseko se-ceramic senziwe nge-artificial synthesis kunye ne-teknoloji ephezulu, kwaye isakhiwo sayo sangaphakathi siyafana kwaye sineempawu ezintle zokudambisa i-vibration. Xa ujongana nokungcangcazela ngokubanzi, kunokudala indawo yokusebenza ezinzileyo yoxinzelelo oluchanekileyo lweqonga lomoya elidadayo. Nangona kunjalo, ebusweni bamandla aphezulu kunye nokunyakaza okuzinzileyo, amandla ayo okunciphisa i-vibration angaphantsi kancinci kunesiseko se-granite, kwaye kunzima ukunciphisa ukuphazamiseka kwe-vibration kwinqanaba eliphantsi elifanayo, elinokuthi libe nempembelelo ethile kwintshukumo ye-ultra-precision yeqonga.
Ukugcinwa ngokuchanekileyo: ukwandiswa okuphantsi kweenzuzo zendalo kunye nokulawulwa kokwenziwa kokuchaneka
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-static yoxinzelelo lomoya lokulungelelaniswa kakuhle kwelensi yeteleskopu idityaniswe nesiseko segranite, nokuba umahluko wobushushu phakathi kwemini nobusuku ubalulekile, inokuqinisekisa ukuba ukuchaneka kokumiswa kwelensi kugcinwa kwinqanaba le-submicron, inceda izazi ngeenkwenkwezi ukuba zibambe amandla afihlakeleyo wemizimba ekude.
Izixhobo ze-Ceramic zigqwesileyo malunga nokuzinza kwe-thermal, kwaye i-coefficient yokwandiswa kwe-thermal yezinye ii-ceramics ezisebenza kakhulu zinokuba ziphantsi malunga ne-zero kwaye zinokulawulwa ngokuchanekileyo ngokuqulunqwa kunye nenkqubo. Kwezinye izixhobo zokulinganisa ubushushu obuphezulu obuchanekileyo, isiseko se-ceramic sinokugcina ubungakanani obuzinzile xa ubushushu buguquka, ukuqinisekisa ukuchaneka kokuhamba kweqonga elichanekileyo le-static yoxinzelelo lomoya. Nangona kunjalo, ukuzinza kwayo kokuchaneka kwexesha elide kwizicelo eziphathekayo kuchaphazeleka yimiba efana nokuguga kwezinto kwaye kufuneka kuqinisekiswe ngakumbi.
Ukuqina: Ubulukhuni obuphezulu belitye lendalo kunye nokugqwala kwezixhobo zokwenziwa zokwenziwa
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 salo 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 zinobunkunkqele, kukho umngcipheko wokugqabhuka xa kuchaphazeleke ngengozi.
Isiseko se-ceramic asinzima nje kuphela, kodwa sinokumelana nokugqwesa okugqwesileyo. Kwiindawo zemizi-mveliso apho kukho umngcipheko wokubola kweekhemikhali, ezifana nokuchaneka kwamaqonga e-hydrostatic air flotation kwizixhobo zokuhlola imveliso yeekhemikhali, iziseko ze-ceramic zixhathisa iigesi ezitshabalalisayo okanye ulwelo, ukugcina ingqibelelo yomhlaba kunye neepropathi zoomatshini ixesha elide. Kwimeko-bume egqithisileyo efana nokufuma okuphezulu, ukuzinza kwesiseko se-ceramic kungcono kunesiseko segranite.
Iindleko zokuvelisa kunye nobunzima bokuqhuba: umceli mngeni wokumbiwa kwelitye lendalo kunye nomda wobuchwephesha wokudityaniswa kokwenziwa
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.
Ukwenziwa kwesiseko se-Ceramic kuxhomekeke kwi-synthesis ephezulu kunye nobuchwepheshe obuchanekileyo bokusebenza, ukusuka ekulungiseleleni izinto ezikrwada, ukubumba ukuya kwi-sintering, inyathelo ngalinye lifuna ukulawulwa ngokuchanekileyo. Uphando lwakwangoko kunye nophuhliso kunye notyalo-mali lwezixhobo mkhulu, umda wobugcisa uphezulu. Nangona kunjalo, kunye nokwandiswa komlinganiselo wemveliso, ixabiso lilindeleke ukuba lincitshiswe, kwaye linamandla angabizi kakhulu kwizicelo eziphezulu.
Ngokubanzi, iziseko ezichanekileyo zegranite zisebenza kakuhle ekuzinzeni ngokubanzi kunye nokuqina okuqhelekileyo, ngelixa iziseko ze-ceramic zineenzuzo ezizodwa ekuguquguqukeni kobushushu obugqithisileyo kunye nokuqina kwe-corrosion. Ukukhethwa kwesiseko kufuneka kusekelwe kwimeko yesicelo esithile, iimeko zokusingqongileyo kunye neendleko zohlahlo lwabiwo-mali lweqonga elichanekileyo le-static yoxinzelelo lomoya.
