Isisekelo se-granite asiyona nje isisekelo; siyi-stabilizer eyisisekelo ye-metrology enembile kakhulu, amathuluzi omshini, kanye nezinhlelo zokukhanya ezithuthukisiwe. Ekhethwe ngenxa yokuqina kwayo okungokwemvelo, ubulukhuni obuphezulu, kanye nokukhula okuphansi kakhulu kokushisa, isisekelo se-granite enembile, ikakhulukazi esenziwe nge-ZHHIMG® Black Granite enobukhulu obuphezulu (≈3100 kg/m³), iqinisekisa ukuthi ukunemba kwezinga le-nanometer kuyafinyeleleka futhi kuyasimeme. Kodwa-ke, ngisho nesisekelo esizinzile kakhulu sidinga ukunakekelwa ngokucophelela nokunamathela ezimisweni eziqinile ukuze kugcinwe ukusebenza kwaso okuqinisekisiwe phakathi nomjikelezo waso wokuphila isikhathi eside.
Ukufinyelela ukunemba okuhlala isikhathi eside kuqala ngokufakwa nokuphathwa kwemvelo. Ipulatifomu lapho isisekelo se-granite sibekwe khona kumele siqine ngokuphelele, sibe sezingeni, futhi singabi namaphuzu okucindezeleka asendaweni. Noma yikuphi ukungalingani noma ukungazinzi esisekelweni kungadala ukucindezeleka okungalingani ku-granite, kubeke engcupheni ukuthamba kwayo nokuqina kwayo—into esiyinciphisa ngokucophelela ngaphakathi kwamahholo ethu okuhlangana alawulwayo angu-10,000 m². Ngaphezu kwalokho, imvelo ngokwayo kumele ilawulwe. Ukuchayeka emswakama ngokweqile kungaholela ekwandeni kwe-hygroscopic ngaphakathi kwesakhiwo setshe, okungase kubangele ukuguquka, kuyilapho ukusondela emithonjeni yokushisa noma amasimu anamandla kagesi kungaphazamisa izinsimbi ezifakwe esisekelweni. Ukusebenza kahle kudinga indawo eyomile, enomoya omuhle enokushintshashintsha okuncane kwezinga lokushisa.
Ngesikhathi sokusebenza kwansuku zonke, ukuphathwa ngokuqonda kubaluleke kakhulu. Izisekelo zegranite zenzelwe ukuzinza okungaguquki nokuguquguqukayo ngaphansi kwemithwalo yazo elinganisiwe, kodwa azithinteki ekusetshenzisweni kabi. Abasebenzi kumele banamathele ngokuqinile emkhawulweni womthwalo oshiwo wesisekelo, baqinisekise ukuthi isisindo sisatshalaliswa ngokulinganayo ukuvimbela ukugoba kwendawo noma ukuqhekeka kokucindezeleka okungabeka engcupheni imishini efakiwe. Ukuwisa amathuluzi, imithelela ebukhali, noma ukubeka izinto ezisindayo emaphethelweni kungabangela umonakalo ongenakulungiswa ku-geometry yomhlaba ocwengisiswe kakhulu. Uma isisekelo esikhulu segranite kufanele sithuthwe, kufanele kusetshenziswe amathuluzi akhethekile kuphela, anesisindo esilinganiselwe, okwenza ukunyakaza kancane futhi ngamabomu ukugwema ukushaqeka. Ngemva kokuthutha, inqubo yokulungisa kabusha ngokuphelele kanye nokulinganisa iyadingeka ukuze kubuyiselwe ukuzinza kwesisekelo sesisekelo.
Indlela yokulungisa nokuhlanza kumele ibe nembambo ukuze kuvikelwe indawo elinganisiwe. Ukuhlanza njalo kufanele kufake indwangu ethambile neyomile kuphela. Okubaluleke kakhulu, izinto zokuhlanza ezingathathi hlangothi, ezingaboliyo kuphela—ezenzelwe i-granite—ezenzelwe ukususa izinsalela eziqinile. Izinto ezi-acidic noma ze-alkaline zingachoboza indawo ecwebezelisiwe kakhulu, zibhubhise ukuqeda okunembile. Ngaphezu kwalokho, ukuvikelwa ekulimaleni ngokomzimba kubalulekile; amathuluzi ensimbi, ama-probe, noma izinto zokusebenza akufanele neze zidonswe phezu kwendawo. Ezindaweni ezisetshenziswa kakhulu noma ezibekwa njalo izingxenye, ukusebenzisa ama-cushioning pads angaboli kuyindlela elula kodwa ephumelelayo yokuvimbela ukuklwebheka okuncane, ukuqinisekisa ukuthi isisekelo sigcina ubuqotho obudingekayo ukuze kuqinisekiswe iBanga 00/0.
Okokugcina, ubuqotho besikhathi eside besisekelo se-granite buncike esimisweni sokulinganisa esiqinile. Nakuba ukuzinza kwe-granite kuphakeme kunensimbi, ukunemba kobuso kuyawohloka kancane kancane ngenxa yokuguga okuvamile kanye nezinguquko ezincane zemvelo. Kuye ngobukhulu bokusetshenziswa kanye nebanga lokunemba elidingekayo, ukuhlolwa okwenziwa njalo—ngokuvamile kusukela ngekota kuya konyaka—kumele kwenziwe ochwepheshe be-metrology abaqinisekisiwe besebenzisa izinsimbi ezinembe kakhulu, njenge-Renishaw Laser Interferometers noma amazinga e-WYLER Electronic. Amarekhodi aphelele alezi zinsuku zokulinganisa, idatha, kanye nezenzo zokulungisa kubalulekile ekugcineni ukulandeleka kwesisekelo nokufakazela ukufaneleka kwaso okuqhubekayo emisebenzini enembile kakhulu esisekelayo. Ngokunamathela kulezi zinqubo zokusebenza eziqinile, abasebenzisi bangasebenzisa ngokugcwele ukuzinza kwe-ZHHIMG® Granite Base, baqinisekise ukuthi ukuzibophezela kwabo ekuqondeni kuhlala isikhathi eside.
