Igranite yinto eguquguqukayo nehlala ixesha elide esetyenziswe kangangeenkulungwane kwiindlela ezahlukeneyo zokusebenza, ukusuka kwizakhiwo ukuya kwimifanekiso eqingqiweyo. Amandla ayo endalo kunye nokumelana nokuguguleka kwayo kuyenza ilungele izixhobo ezichanekileyo kwizicelo zemetrology.
Izixhobo zegranite ezichanekileyo zisetyenziswa kakhulu kwizicelo ze-metrology ngenxa yokuzinza kwazo okugqwesileyo kunye nokuchaneka kwazo. I-Granite's low thermal expansion coefficient kunye nokuqina okuphezulu kwenza ukuba ibe yinto efanelekileyo yokwenza izixhobo zokulinganisa ngokuchanekileyo ezifana namaqonga, ii-angle plates kunye neerula. Ezi zixhobo zibonelela ngesiseko esizinzileyo nesithembekileyo sezixhobo zokulinganisa, ukuqinisekisa iziphumo ezichanekileyo neziphindaphindwayo.
Enye yezona nzuzo ziphambili zokusebenzisa izinto zegranite ezichanekileyo kwizicelo zemetrology kukukwazi kwazo ukugcina uzinzo olulinganayo ngokuhamba kwexesha. Ngokungafaniyo nezinye izinto, igranite ayigobi okanye iguquguquke lula, ukuqinisekisa ukuba imilinganiselo ihlala ihambelana kwaye ithembekile. Oku kubaluleke kakhulu kumashishini afana neenqwelo moya, iimoto kunye nemveliso, apho imilinganiselo echanekileyo ibaluleke kakhulu kulawulo lomgangatho kunye nokuthobela imigangatho yoshishino.
Ukongeza ekuzinzeni kwazo, izinto zegranite ezichanekileyo zibonelela ngeempawu ezintle zokudambisa ukungcangcazela, nto leyo ibalulekileyo kwizicelo zemetrology njengoko nokungcangcazela okuncinci kunokuchaphazela ukuchaneka kokulinganisa. Oku kwenza igranite ibe yinto efanelekileyo yokwenza iqonga lokulinganisa elizinzileyo nelithembekileyo, ukuqinisekisa ukuba imilinganiselo ayichaphazeleki ziimeko zangaphandle.
Ukongeza, ukumelana kwendalo kwegranite nokugqwala kunye nokuguga kwenza ukuba ibe lukhetho oluhlala ixesha elide nolungabizi kakhulu kwiindlela zokulinganisa. Ukuqina kwayo kuqinisekisa ukuba iindawo ezichanekileyo ezenziwe ngegranite zinokumelana nokusetyenziswa kakhulu kunye neemeko ezinzima zokusingqongileyo ngaphandle kokuphazamisa ukuchaneka kwazo.
Ngamafutshane, izinto zegranite echanekileyo zifanelekile kwizicelo zemetrology ngenxa yokuzinza kwazo okugqwesileyo, ukuchaneka, kunye nokuqina. Njengoko iimfuno zokuchaneka kokulinganisa kunye nokuthembeka ziqhubeka zisanda kumashishini, ukusetyenziswa kwegranite kwimetrology kusenokwenzeka ukuba kusasazeka ngakumbi, nto leyo eya kuseka udumo lwayo njengezinto ezikhethwayo zobunjineli bokuchaneka.
