Emhlabeni we-ultra-precision metrology, ithuluzi lokulinganisa i-granite aliyona nje ibhulokhi elisindayo letshe; iyindinganiso eyisisekelo okwahlulelwa ngayo zonke ezinye izilinganiso. Ukunemba kokugcina kohlangothi—okuzuzwe kububanzi be-micron kanye ne-sub-micron—kuqala kudala ngaphambi kwenqubo yokugcina, yokuqwayiza ngokucophelela. Kodwa yiziphi izinqubo zokuqala ezabeka ngempela isisekelo sokunemba okunjalo okungenakuqhathaniswa? Iqala ngezigaba ezimbili ezibucayi, eziyisisekelo: ukukhethwa okuqinile kwempahla ye-granite eluhlaza kanye nenqubo yokusika enembayo ephezulu esetshenziselwa ukuyilolonga.
Ubuciko Nesayensi Yokukhetha Izinto
Akuwona wonke ama-granite adalwe alingana, ikakhulukazi uma umkhiqizo wokugcina kufanele usebenze njengethuluzi lokulinganisa elizinzile, lereferensi njengepuleti elingaphezulu, i-tri-square, noma i-straight edge. Inqubo yokukhetha ingeyesayensi ejulile, igxile ezintweni ezibonakalayo ezingokwemvelo eziqinisekisa ukuzinza kobukhulu phakathi namashumi eminyaka.
Sifuna ngokukhethekile izinhlobo zegwadle ezimnyama ezixinene kakhulu. Umbala ukhombisa ukugcwala okuphezulu kwamaminerali aminyene, amnyama, njenge-hornblende, kanye nesakhiwo sokusanhlamvu esicolekile. Lokhu kuqamba akuxoxiswana ngakho ukuze kwenziwe umsebenzi onemba ngezizathu ezibalulekile ezimbalwa. Okokuqala, i-Low Porosity kanye ne-High Density yikona okubalulekile: isakhiwo esiqinile, esiqinile sinciphisa i-void yangaphakathi futhi sikhulise ukuminyana, okuhumusha ngokuqondile izici eziphakeme zokumanzisa ngaphakathi. Lo mthamo ophezulu wokumanzisa ubalulekile ekudlidlizeni komshini okumunca ngokushesha, ukuqinisekisa ukuthi indawo yokulinganisa ihlala izinzile ngokuphelele. Okwesibili, okokusebenza kufanele kubonise I-Coefficient Ephansi kakhulu Yokwanda Kwe-Thermal (COE). Lesi sakhiwo sibalulekile, njengoba sinciphisa ukunwetshwa noma ukusifinyela ngokushintshashintsha kwezinga lokushisa okuvamile endaweni yokulawula ikhwalithi, iqinisekisa ukuthi ithuluzi ligcina ubuqotho balo bobukhulu. Okokugcina, igwadle elikhethiwe kufanele libe namandla acindezelayo aphezulu kanye Nokusabalalisa Amaminerali Okufanayo. Lokhu kufana kuqinisekisa ukuthi okokusebenza kuphendula ngokubikezela ngesikhathi sokusikwa okulandelayo futhi, okubaluleke kakhulu, isigaba esibalulekile sokudonsa ngesandla, okusivumela ukuthi sizuze futhi sibambe ukubekezelelana kwethu okudingayo.
Inqubo Yokusika Okunembe Kakhulu
Uma ibhulokhi efanelekile isikhishiwe ekwalini, isigaba sokuqala sokubumba—ukusika—kuyinqubo yezimboni eyinkimbinkimbi eklanyelwe ukunciphisa ukucindezeleka kwezinto futhi ibeke isiteji sokuqeda ukunemba okukhulu. Izindlela zokusika ezijwayelekile zamatshe akwanele; ukunemba kwegwadle kudinga amathuluzi akhethekile.
Indlela yamanje yesimanje yokusikwa kwebhulokhi ye-granite enkulu yi-Diamond Wire Saw. Le ndlela ithatha indawo yezindwani eziyindilinga zendabuko ngeluphu eqhubekayo yekhebula lensimbi enamandla amakhulu eshumekwe namadayimane ezimboni. Ukusetshenziswa kwale ndlela kunikeza izinzuzo ezihlukile: kuqinisekisa Ukucindezeleka Okuncishisiwe Nokushisa ngoba isaha yentambo yedayimane isebenza ngokuqhubekayo, ukunyakaza okunezinhlangothi eziningi, okusabalalisa amandla okusika ngokulinganayo kuyo yonke into. Lokhu kunciphisa ubungozi bokwethula ingcindezi eyinsalela noma imifantu emincane ku-granite—ingozi evamile nge-single-pass, izindlela zokusika ezinomthelela omkhulu. Okubi kakhulu, inqubo ivamise ukuba manzi, kusetshenziswa ukugeleza kwamanzi njalo ukupholisa ucingo nokususa uthuli lwegwadle, ngaleyo ndlela kuvinjwe umonakalo wendawo oshisayo ongafaka engcupheni ukuzinza kwesikhathi eside kwento. Le nqubo iqhubeka ivumela Ukusebenza Nesikali, okuvumela ukubunjwa okunembile kwamabhulokhi amakhulu-okudingekayo kumapuleti angaphezulu efomethi enkulu yegwadle noma izisekelo zomshini-ngokulawula okungakaze kubonwe ngaphambili, okuhlinzeka ngejiyomethri yokuqala enembile enciphisa kakhulu isikhathi nokumosha kwezinto ezibonakalayo ezihilelekile ezigabeni zokugaya ezimahhadlahhadla.
Ngokugxila ngokungaphezi ekukhethweni kwezinto eziminyene kakhulu, ezinzile nasekusebenziseni amasu okusika athuthukile, okunciphisa ingcindezi, siqinisekisa ukuthi ithuluzi ngalinye le-ZHHIMG lokulinganisa igwadle lakhiwe ngekhwalithi engokwemvelo edingekayo ukuze kukale usayizi onembe kakhulu emhlabeni. Ukweqa ngokucophelela okulandelayo kuyisenzo sokugcina kuphela senqubo yokukhiqiza eklanywe ngokucophelela.
