Ukukhethwa kwezinto eziyisisekelo kudlala indima ebalulekile ekwakhiweni kwamamojula okunyakaza okunembile kakhulu. Izisekelo zokunemba kwe-granite kanye nezisekelo zokuphonsa amaminerali, njengezinketho ezimbili eziyinhloko, ngayinye inezici ezihlukile ezihluke kakhulu ngokuya ngokuzinza, ukugcinwa kokunemba, ukuqina, kanye nezindleko.
Ukuzinza: Ukuqina kwemvelo uma kuqhathaniswa nezinto ezihlanganisiwe zokwenziwa
Ngemva kwezigidi zeminyaka yokuguqulwa kwejiyoloji, i-granite yakha isakhiwo esiminyene kakhulu nesifanayo ngokubopha kwemvelo kwe-quartz, i-feldspar, kanye nezinye izimbiwa. Ezindaweni zezimboni lapho imishini emikhulu ikhiqiza khona ukudlidliza okunamandla, isakhiwo esiyinkimbinkimbi se-crystalline se-granite sinciphisa ngempumelelo lokhu kuphazamiseka, sinciphise ubukhulu bokudlidliza obudluliselwa kumamojula okunyakaza okuhamba ngokunemba okuphezulu emoyeni ngaphezu kuka-80%. Lokhu kuqinisekisa ukusebenza okubushelelezi ngesikhathi sokucubungula noma imisebenzi yokuhlola ngokunemba okuphezulu, njengokwenza amaphethini anembile ama-chip kagesi ezinqubweni ze-photolithography.
Izisekelo zokubumba amaminerali zakhiwe ngezinhlayiya zamaminerali ezixutshwe nezihlanganisi ezikhethekile, okuholela esakhiweni sangaphakathi esifanayo esinezakhiwo ezinhle zokudambisa ukudlidliza. Ngenkathi zihlinzeka nge-buffering ephumelelayo yokudlidliza okujwayelekile futhi zidala indawo yokusebenza ezinzile yamamojula okunyakaza okuntantayo emoyeni, ukusebenza kwazo ngaphansi kokudlidliza okunamandla aphezulu nokuqhubekayo kuphansi kancane kunokwezisekelo ze-granite. Lo mkhawulo ungase wethule ukungalungi okuncane ekusetshenzisweni okunembe kakhulu.
Ukugcinwa Kokunemba: Ukukhula okuphansi kwemvelo uma kuqhathaniswa nokufinyela okulawulwayo
I-Granite idume nge-coefficient yayo ephansi kakhulu yokwanda kokushisa (ngokuvamile 5–7 × 10⁻⁶/°C). Ngisho nasezindaweni ezinokuguquguquka okukhulu kokushisa, izisekelo zokunemba kwe-granite zibonisa izinguquko ezincane kakhulu. Isibonelo, ekusetshenzisweni kwezinkanyezi, amamojula okunyakaza okuqondile okusekelwe ku-granite aqinisekisa ukunemba kokubeka ilensi ezingeni le-submicron kuma-telescope, okuvumela izazi zezinkanyezi ukuthi zithwebule imininingwane eyinkimbinkimbi yezidalwa zasezulwini ezikude.
Izinto zokubumba amaminerali zingakhiwa ukuze zithuthukise futhi zilawule izici zokunwetshwa kokushisa, kufezwe ama-coefficient afana noma aphansi kunalawo e-granite. Lokhu kuzenza zifaneleke imishini yokulinganisa ukunemba okuphezulu ezwela izinga lokushisa. Kodwa-ke, ukuzinza kwesikhathi eside kokunemba kwazo kuhlala kungaphansi kokuqinisekiswa ngenxa yezici ezifana nokuguga kwe-binder, okungaholela ekusebenzeni okunciphile ngokuhamba kwesikhathi eside kokusetshenziswa.
Ukuqina: Ukuqina okuphezulu kwetshe lemvelo uma kuqhathaniswa nezinhlanganisela ezingakhathali
Ubulukhuni obuphezulu be-Granite (isikali se-Mohs: 6–7) bunikeza ukumelana okuhle kakhulu nokuguguleka. Emalabhorethri esayensi yezinto zokwakha, izisekelo ze-granite zamamojula okunyakaza asetshenziswa njalo emoyeni aqondile kakhulu amelana nokungqubuzana okude okuvela kuma-slider, okwandisa imijikelezo yokulungisa ngaphezu kuka-50% uma kuqhathaniswa nezisekelo ezivamile. Naphezu kwale nzuzo, ukuqhekeka kwe-granite kubeka ingozi yokuphuka lapho kushayisana ngengozi.
Izisekelo zokuphonsa amaminerali zibonisa izakhiwo ezinhle kakhulu zokulwa nokukhathala, zigcina ubuqotho besakhiwo ngesikhathi sokunyakaza okuphindaphindwayo okuqhubekayo kwamamojula antantayo emoyeni anembile kakhulu. Ngaphezu kwalokho, zibonisa ukumelana nokugqwala kwamakhemikhali okuthambile, okuthuthukisa ukuqina ezindaweni ezigqwala kancane. Kodwa-ke, ezimweni ezimbi kakhulu njengomswakama ophezulu, i-binder ngaphakathi kwezisekelo zokuphonsa amaminerali ingase yonakale, ibeke engcupheni ukuqina kwayo konke.
Izindleko Zokukhiqiza Nobunzima Bokucubungula**: Izinselele zokukhishwa kwamatshe emvelo uma kuqhathaniswa nezinqubo zokubumba ezenziwe ngokwenziwa
Ukumbiwa kwe-granite kanye nokuthuthwa kwayo kuhilela izinto eziyinkimbinkimbi, kuyilapho ukucubungula kwayo kudinga imishini namasu athuthukile. Ngenxa yobunzima bayo obukhulu kanye nokuqhekeka, imisebenzi efana nokusika, ukugaya, kanye nokupholisha ivame ukuholela emananini aphezulu ezinto ezilahliwe, okunyusa izindleko zokukhiqiza.
Ngokuphambene nalokho, ukukhiqizwa kwezisekelo zokubumba amaminerali kudinga isikhunta nezinqubo ezithile. Nakuba ukuthuthukiswa kwesikhunta kokuqala kubangela izindleko ezinkulu, ukukhiqizwa kwenqwaba okulandelayo kuba yinzuzo ngokwezomnotho uma isikhunta sesizinzile.
