Ezweni le-metrology enembile kakhulu, ithuluzi lokulinganisa i-granite aliyona nje ibhloko elisindayo letshe; liyindinganiso eyisisekelo lapho zonke ezinye izilinganiso zahlulelwa khona. Ukunemba kokugcina kobukhulu—okufinyelelwe kububanzi be-micron kanye ne-sub-micron—kuqala isikhathi eside ngaphambi kwenqubo yokugcina, ecophelelayo yokuhlanganisa. Kodwa yiziphi izinqubo zokuqala ezibeka isiteji sokunemba okungenakuqhathaniswa okunjalo? Kuqala ngezigaba ezimbili ezibalulekile, eziyisisekelo: ukukhethwa okuqinile kwezinto ze-granite eluhlaza kanye nenqubo yokusika enembile kakhulu esetshenziswa ukuyibumba.
Ubuciko Nesayensi Yokukhetha Izinto Ezibonakalayo
Akuyona yonke i-granite edalwa ngokulinganayo, ikakhulukazi lapho umkhiqizo wokugcina kufanele usebenze njengethuluzi lokulinganisa elizinzile, elisezingeni lokubhekisela njengepuleti elingaphezulu, isikwele esi-tri, noma umphetho oqondile. Inqubo yokukhetha ingokwesayensi kakhulu, igxile ezicini zomzimba eziqinisekisa ukuzinza kobukhulu phakathi namashumi eminyaka.
Sifuna ngokukhethekile izinhlobo zegranite emnyama enobukhulu obuphezulu. Umbala ubonisa ukugcwala okuphezulu kwamaminerali aminyene, amnyama, njenge-hornblende, kanye nesakhiwo sezinhlamvu ezincane. Lokhu kwakheka akunakuxoxiswana ngakho ngomsebenzi onembile ngezizathu eziningana ezibalulekile. Okokuqala, i-Porosity Ephansi kanye ne-High Density kubaluleke kakhulu: isakhiwo esiqinile, esinobukhulu obuncane sinciphisa izikhala zangaphakathi futhi sandisa ubuningi, okuhunyushwa ngqo ezicini zokunciphisa umswakama zangaphakathi eziphakeme. Lo mthamo wokunciphisa umswakama ophezulu ubalulekile ekumunceni ngokushesha ukudlidliza komshini, ukuqinisekisa ukuthi indawo yokulinganisa ihlala izinzile ngokuphelele. Okwesibili, izinto kumele zibonise i-Coefficient Ephansi Kakhulu Yokukhulisa Ukushisa (i-COE). Lesi sici sibalulekile, njengoba sinciphisa ukwanda noma ukufinyela ngokushintshashintsha kwezinga lokushisa okuvamile endaweni yokulawula ikhwalithi, okuqinisekisa ukuthi ithuluzi ligcina ubuqotho balo obulinganayo. Okokugcina, igranite ekhethiwe kumele ibe namandla aphezulu okucindezela kanye nokuSasazwa Kwamaminerali Okufanayo. Lokhu kufana kuqinisekisa ukuthi izinto ziphendula ngokubikezela ngesikhathi sokusika okulandelayo futhi, okubaluleke kakhulu, isigaba esibalulekile sokubopha ngesandla, okusivumela ukuthi sifinyelele futhi sibambe ukubekezelelana kwethu okudingakalayo kokuthamba.
Inqubo Yokusika Enembile Kakhulu
Uma ibhulokhi eluhlaza efanelekile isikhishiwe edwaleni, isigaba sokuqala sokubumba—ukusika—yinqubo yezimboni eyinkimbinkimbi eyenzelwe ukunciphisa ukucindezeleka kwezinto futhi ibeke isiteji sokuqedela ngokunemba okukhulu. Izindlela zokusika ngokhuni ezijwayelekile azanele; i-granite enembile idinga amathuluzi akhethekile.
Indlela yamanje yobuchwepheshe bokusika amabhlogo e-granite amakhulu yi-Diamond Wire Saw. Le ndlela ithatha indawo yama-blade ajwayelekile ayindilinga ngomjikelezo oqhubekayo wekhebula lensimbi elinamandla aphezulu elifakwe amadayimane ezimboni. Ukusetshenziswa kwale ndlela kunikeza izinzuzo ezihlukile: kuqinisekisa Ukucindezeleka Okuncishisiwe Nokushisa ngoba i-diamond wire saw isebenza ngokunyakaza okuqhubekayo, okuqondiswe ngezindlela eziningi, okusabalalisa amandla okusika ngokulinganayo kuyo yonke into. Lokhu kunciphisa ingozi yokungenisa ukucindezeleka okusele noma imifantu emincane ku-granite—ingozi evamile ngezindlela zokusika ezithinta kakhulu. Okubaluleke kakhulu, inqubo ivame ukuba manzi, isebenzisa umfudlana wamanzi oqhubekayo ukupholisa intambo nokususa uthuli lwe-granite, ngaleyo ndlela kuvinjelwe umonakalo wokushisa wendawo ongalimaza ukuzinza kwesikhathi eside kwezinto. Le ndlela ivumela nokusebenza kahle kanye nokulinganisa, okuvumela ukwakheka okunembile kwamabhlogo amakhulu—adingekayo kumapuleti aphezulu noma izisekelo zomshini—ngokulawula okungakaze kubonwe, okuhlinzeka nge-geometry yokuqala enembile enciphisa kakhulu isikhathi kanye nokuchitha kwezinto ezihilelekile ezigabeni zokugaya ezinzima ezilandelayo.
Ngokugxila ngokungaphezi ekukhetheni izinto eziqinile neziqinile ezinhle kakhulu kanye nokusebenzisa amasu okusika athuthukile, anciphisa ukucindezeleka, siqinisekisa ukuthi wonke amathuluzi okulinganisa i-granite e-ZHHIMG akhiqizwa ngekhwalithi edingekayo yokulinganisa ubukhulu obunembile kakhulu emhlabeni. Ukuhlanganisa ngokucophelela okulandelayo kuyisenzo sokugcina enqubweni yokukhiqiza eklanywe ngokucophelela.
