Emkhakheni wokukhiqiza wezimboni, umshini wokulinganisa onama-three-coordinate (CMM) uyithuluzi elibalulekile lokufeza ukuhlolwa okunembile kobukhulu kanye nokuhlolwa kokubekezelela isimo nesikhundla, futhi ukunemba kwawo kokulinganisa kuthinta ngqo ikhwalithi yomkhiqizo. Amapulatifomu okunemba kwe-granite, ngokusebenza kwawo okuvelele, abe yisinqumo esiyisisekelo esifanele semishini yokulinganisa onama-three-coordinate, enikeza iziqinisekiso ezithembekile zokutholwa okunembile kakhulu.
1. Ukunemba okuphezulu kakhulu kanye nokuqina
Amapulatifomu okunemba kwe-granite anokuqina okuhle kakhulu kanye ne-coefficient ephansi kakhulu yokwanda kokushisa, okuyi-(4-8) ×10⁻⁶/℃ kuphela. Endaweni yezimboni eyinkimbinkimbi neguquguqukayo, noma ngabe izinga lokushisa liyashintshashintsha, ushintsho lobukhulu bepulatifomu alunamsebenzi, okugwema ngempumelelo amaphutha okulinganisa abangelwa ukuguqulwa kokushisa. Okwamanje, isakhiwo sangaphakathi sekristalu se-granite siminyene. Ngemuva kwezigidigidi zeminyaka yesenzo se-geological, ukucindezeleka kwangaphakathi sekuqediwe ngokwemvelo, futhi ngeke kube nokuguquguquka kokuguga. Lokhu kuqinisekisa ukuzinza kwesikhathi eside kwereferensi yokulinganisa futhi kugcina ukunemba kokubeka kanye nokunemba kokubeka okuphindaphindwayo komshini wokulinganisa ohlanganisa ama-three-coordinate ezingeni eliphezulu ngaso sonke isikhathi.
Okwesibili, ukusebenza okuhle kakhulu kokulwa nokudlidliza kanye nokunciphisa umswakama
Ukudlidliza okubangelwa ukusebenza kwamathuluzi omshini kanye nokuqala nokuma kwemishini endaweni yokukhiqiza kungaphazamisa ukunemba kokutholwa komshini wokulinganisa onezinhlanganisela ezintathu. I-Granite inezakhiwo ezinhle kakhulu zokudambisa, enesilinganiso sokudambisa esifinyelela ku-0.05-0.1, esinganciphisa ngokushesha amandla okudlidliza kwangaphandle. Lapho ukudlidliza kwangaphandle kudluliselwa epulatifomu, i-granite ingacindezela ukudlidliza ngesikhathi esifushane, inciphise ukuphazamiseka kokudlidliza ngesikhathi senqubo yokulinganisa, iqinisekise ukunemba kokuxhumana phakathi kwe-probe yokulinganisa kanye nobuso be-workpiece, futhi yenze idatha yokulinganisa ibe neqiniso futhi ithembeke kakhudlwana.
Okwesithathu. Ubulukhuni obuphezulu kanye nokumelana nokuguguleka
I-Granite inobunzima obungu-6 kuya ku-7 esikalini se-Mohs, ubuningi obusukela ku-2.7 kuya ku-3.1g/cm³, kanye nokumelana okuhle kakhulu nokuguguleka kwendawo. Ngesikhathi sokusetshenziswa isikhathi eside komshini wokulinganisa onama-three coordinate, ukulayisha nokukhipha njalo izinto zokusebenza kanye nokunyakaza kwama-probe okulinganisa akuvamile ukubangela ukuguguleka ebusweni bepulatifomu ye-granite. Ngisho nangemva kweminyaka yokusetshenziswa, indawo yepulatifomu isakwazi ukugcina ukuthamba nokushelela okuhle, yandisa ngempumelelo impilo yesevisi enembile kakhulu yomshini wokulinganisa onama-three coordinate futhi inciphise izindleko zokulungisa imishini.
Okwesine, ukuzinza okuqinile kwamakhemikhali
Ezindaweni zokukhiqiza zezimboni, kuvame ukuba nezinto zamakhemikhali ezifana noketshezi lokusika namafutha okugcoba, kanti ezinye zingase zihambisane namagesi agqwalisayo. I-Granite inezakhiwo zamakhemikhali ezizinzile, ububanzi obukhulu bokubekezelela i-pH (1-14), ingamelana nokuguguleka kwezinto zamakhemikhali ezivamile, futhi ayithambekeli ekugqwaleni noma ekugqwaleni. Lesi sici asivikeli nje kuphela ipulatifomu ngokwayo kodwa futhi siqinisekisa indawo yokusebenza ehlanzekile yomshini wokulinganisa onezixhumanisi ezintathu, ukuvimbela ukunemba kokulinganisa kanye nokuphila kwenkonzo yemishini ukuthi ingathinteki ukungcola kwamakhemikhali.
Amapulatifomu okunemba kwe-granite, anezinzuzo zawo zokunemba okuphezulu, ukuzinza okuphezulu, ukumelana nokudlidliza, ukumelana nokuguguleka kanye nokuqina kwamakhemikhali, ahlinzeka ngesisekelo esiqinile sokutholakala okunembile kwemishini yokulinganisa enama-three coordinate futhi adlala indima engenakuphikiswa ekuxhumaneni kokulawula ikhwalithi yokukhiqiza kokunemba kwesimanje.
